Stuart Kauffman has, in recent writings, developed a thought-provoking and influential argument for strong emergence. The outcome is his Theory of the Adjacent Possible (TAP). According to TAP, the biosphere constitutes a non-physical domain qualitatively distinct from the physical domain. The biosphere exhibits strongly emergent properties such as agency, meaning, value and creativity that cannot, in principle, be reduced to the physical. In this paper, I argue that TAP includes various (explicit or implicit) metaphysical commitments: commitments to (1) (...) scientific realism, (2) downward causation and teleology, and (3) modal realism. If TAP is to hang together as the kind of robust philosophical thesis it evidently aspires to be, it needs an account – an account that is currently absent – of its metaphysical commitments. It is however unclear how such an account can be developed since various dilemmas present themselves when one explores how subscribers to TAP might do so. (shrink)

Most causal discovery algorithms in the literature exploit an assumption usually referred to as the Causal Faithfulness or Stability Condition. In this paper, we highlight two components of the condition used in constraint-based algorithms, which we call “Adjacency-Faithfulness” and “Orientation- Faithfulness.” We point out that assuming Adjacency-Faithfulness is true, it is possible to test the validity of Orientation- Faithfulness. Motivated by this observation, we explore the consequence of making only the Adjacency-Faithfulness assumption. We show that the familiar PC algorithm (...) has to be modified to be correct under the weaker, Adjacency-Faithfulness assumption. The modified algorithm, called Conservative PC (CPC), checks whether Orientation- Faithfulness holds in the orientation phase, and if not, avoids drawing certain causal conclusions the PC algorithm would draw. Howtion: ever, if the stronger, standard causal Faith-. (shrink)

Attempts to ‘naturalize’ phenomenology challenge both traditional phenomenology and traditional approaches to cognitive science. They challenge Edmund Husserl’s rejection of naturalism and his attempt to establish phenomenology as a foundational transcendental discipline, and they challenge efforts to explain cognition through mainstream science. While appearing to be a retreat from the bold claims made for phenomenology, it is really its triumph. Naturalized phenomenology is spearheading a successful challenge to the heritage of Cartesian dualism. This converges with the reaction against Cartesian thought (...) within science itself. Descartes divided the universe between res cogitans, thinking substances, and res extensa, the mechanical world. The latter won with Newton and we have, in most of objective science since, literally lost our mind, hence our humanity. Despite Darwin, biologists remain children of Newton, and dream of a grand theory that is epistemologically complete and would allow lawful entailment of the evolution of the biosphere. This dream is no longer tenable. We now have to recognize that science and scientists are within and part of the world we are striving to comprehend, as proponents of endophysics have argued, and that physics, biology and mathematics have to be reconceived accordingly. Interpreting quantum mechanics from this perspective is shown to both illuminate conscious experience and reveal new paths for its further development. In biology we must now justify the use of the word “function”. As we shall see, we cannot prestate the ever new biological functions that arise and constitute the very phase space of evolution. Hence, we cannot mathematize the detailed becoming of the biosphere, nor write differential equations for functional variables we do not know ahead of time, nor integrate those equations, so no laws “entail” evolution. The dream of a grand theory fails. In place of entailing laws, a post-entailing law explanatory framework is proposed in which Actuals arise in evolution that constitute new boundary conditions that are enabling constraints that create new, typically unprestatable, Adjacent Possible opportunities for further evolution, in which new Actuals arise, in a persistent becoming. Evolution flows into a typically unprestatable succession of Adjacent Possibles. Given the concept of function, the concept of functional closure of an organism making a living in its world, becomes central. Implications for patterns in evolution include historical reconstruction, and statistical laws such as the distribution of extinction events, or species per genus, and the use of formal cause, not efficient cause, laws.

The article raises the question of the theoretical and cognitive foundations of sociological observation in the system-communication theory of Niklas Luhmann. Observation of society in its entirety is possible only from within itself, and therefore its observer (sociologist, artist, writer, moralist, politician or participant in a social movement) is necessarily included in the observed object itself. This circumstance gives rise to the paradox of self-applicability or self-reference in their social specification, since generalizing statements about society, if they claim to (...) be universal in description, are always applicable to the statements themselves. It is substantiated that the paradoxes of self- applicability and self-reference, without receiving their resolution, are never- theless performatively realized both in social reality itself and in its theoretical representation, and ensure the function of the social system — reflection of the system and the possibility of comparing one’s own observation resources with the methods of observation of adjacent communication systems. Following logic of self-observation, social theory is supplemented by a self-referential theoretical complex (sub-discipline), called “Self-Descriptions” (the fifth book of N. Luhmann’s fundamental work “Societies of Society”). This additional theory specializes in reconstructing the semantics of the concept of society, how society — in its communications, religion, mass media, art, politics, but today primarily in the optics of science — looked and looks at itself. Such inclu- sion of “Self-Description” (“shorthand”, “scene description”) in the corpus of social theory, as its integral and equal part with the function of describing the formation, semantics and theoretical resources of the theory of society itself, has become an important theoretical innovation in the field of social theory.

In this paper we study the problem of a possibility to use quantum observables to describe a possible combination of the order effect with sequential reproducibility for quantum measurements. By the order effect we mean a dependence of probability distributions on the order of measurements. We consider two types of the sequential reproducibility: adjacent reproducibility ) and separated reproducibility). The first one is reproducibility with probability 1 of a result of measurement of some observable A measured twice, one (...) A measurement after the other. The second one, \, is reproducibility with probability 1 of a result of A measurement when another quantum observable B is measured between two A’s. Heuristically, it is clear that the second type of reproducibility is complementary to the order effect. We show that, surprisingly, this may not be the case. The order effect can coexist with a separated reproducibility as well as adjacent reproducibility for both observables A and B. However, the additional constraint in the form of separated reproducibility of the \ type makes this coexistence impossible. The problem under consideration was motivated by attempts to apply the quantum formalism outside of physics, especially, in cognitive psychology and psychophysics. However, it is also important for foundations of quantum physics as a part of the problem about the structure of sequential quantum measurements. (shrink)

This chapter tackles a number of problems surrounding the emergence and formation of complex societies in the central Andes, principally on the north and central coasts of Peru and their adjacent highlands. While chronology itself will form part of the discussion, there is general agreement in envisaging this process as taking place over a period of some three millennia between c.3000 bc and the beginning of our era. The focus here is on the earlier part of this ‘block’ of (...) time, namely from before 3000 bc to c.1000 bc, or in chronological terms from the Middle Archaic to Middle Formative. The factors that lead to complexity include important changes in social structure and economic systems, but also probable movements and concentrations of populations, against a linguistic background taken into account despite the obvious difficulties in defining it at these time-depths.

The triumph of scientific materialism in the Seventeenth Century not only bifurcated nature into matter and mind and primary and secondary qualities, as Alfred North Whitehead pointed out in Science and the Modern World. It divided science and the humanities. The core of science is the effort to comprehend the cosmos through mathematics. The core of the humanities is the effort to comprehend history and human nature through narratives. The life sciences can be seen as the zone in which the (...) conflict between these two very different ways of comprehending the world collide. Evolutionary theory as defended by Schelling developed out of natural history, but efforts have been made to formulate neo-Darwinism through mathematical models. However, it is impossible to eliminate stories from biology. As Stuart Kauffman argued, mathematical models attempt to pre-state all possibilities, but in evolution there can be adjacent possibles that can be embraced by organisms but cannot be pre-stated. To account for such actions it is necessary to tell stories. Mathematics provides analytic precision allowing long chains of deductions, but tends to deny temporal becoming and cannot do justice to the openness of the future, while narratives focus on processes and events, but lack exactitude that would provide precise deductions and predictions. In advancing mathematics adequate to life, Robert Rosen argued that living beings as anticipatory systems must have models of themselves, and strove to develop a form of mathematics able to model life itself. It has been convincingly argued that narratives are central to human self-creation and they are lived out before being explicitly told. Their models of themselves are first and foremost, stories or narratives. If this is the case, might not living beings as biological entities be characterized by proto-stories or narratives in their models of themselves? Biosemiotics, largely inspired by C.S. Peirce, provides a bridge between mathematical and narrative comprehension, conceiving them as different forms of semiosis. The study of life through biosemiotics could reveal how mathematics and narratives can be understood in relation to each other. This could have implications for how we understand science and the humanities and their relationship to each other. In this paper I will examine work in theoretical biology that might advance these efforts. (shrink)

In strict opposition to the prevailing positivist conception of nature as senseless and deprived of meaning Jakob von Uexküll claimed that a certain planmässigkeit was operative in nature. This idea however might be taken to mean that organic evolution is not itself a creative process but a gradual, if majestic, unfolding of Nature's own master plan. Such an idea would threaten to restore determinism in the center of biological theory, and this would seriously contradict the vision of biosemiotics shared by (...) most of its proponents. It lies at the heart of biosemiotics and of Peircean cosmological philosophy that indeterminacy is primary, that “habit taking” or interpretation are real processes in the world, and therefore that belief in the law of necessity is unfounded. It is suggested that Uexküllian planmässigkeit is in fact reconcilable with a modern non-deterministic understanding. In a certain sense the Umwelten of animals have indeed developed in accordance to a natural planmässigkeit, but this is a plan that incessantly traps life in certain strategic choices and in the same time diversifies the dimensionality of options for dealing with these choices, i. e. “the adjacent possible” in the terms of Stuart Kauffman.

It should now be recognized that codes are central to life and to understanding its more complex forms, including human culture. Recognizing the ‘conventional’ nature of codes provides solid grounds for rejecting efforts to reduce life to biochemistry and justifies according a place to semantics in life. The question I want to consider is whether this is enough. Focussing on Eigen’s paradox of how a complex code could originate, I will argue that along with Barbieri’s efforts to account for the (...) origins of life based on the ribosome and then to account for the refined codes through a process of ambiguity reduction, something more is required. Barbieri has not provided an adequate account of emergence, or the basis for providing such an account. I will argue that Stanley Salthe has clarified to some extent the nature of emergence by conceptualizing it as the interpolation of new enabling constraints. Clearly, codes can be seen as enabling constraints. How this actually happens, though, is still not explained. Stuart Kauffman has grappled with this issue and shown that it radically challenges the assumptions of mainstream science going back to Newton. He has attempted to reintroduce real possibilities or potentialities into his ontology, and argued that radically new developments in nature are associated with realizing adjacent possibles. This is still not adequate. What is also involved, I will suggest, utilizing concepts developed by the French natural philosopher Gilbert Simondon, is ‘transduction’ as part of ‘ontogenesis’ of individuals in a process of ‘individuation’, that is, the emergence of ‘individuals’ from preindividual fields or milieux.

Abstract.Stuart Kauffman's work on complexity and self‐organization echoes ideas found in writings of C. S. Peirce and G. W. F. Hegel. Included in these common threads are the understanding of science as historical narrative, the recognition of emergence as a phenomenon associated with complex systems, and the appreciation of agency as an emergent property that serves as both a creative and determining force in evolution.

This paper proposes a prolegomenal model for the mechanisms through which new styles and schools of art – Cubism or conceptual art, for example – undergo the catalytic, evental transition from potential to actual. The model proposed herein, of fine art as a complex adaptive system that emerges and grows in a manner analogous to that of certain specific forms of biological organization, is predicated on a shift from the residual traces of Greenbergian disciplinary and mediumistic differentiation – grounded in (...) an analytic autonomy – to modes of interaction and aesthetic signal exchange emergent from an autopoietic autonomy – a systemic process of autocatalysis and transformation similar to the recursively generative feedback relations seen in cell metabolism and in ecosystems. This conceptual recalibration leads to a model of artistic eventalization and change that algorithmically unfolds from the adjacent possible as an emergent phenomenon, analogous to the aggregative and spontaneous, self-organizational swarm behavior seen in the flocking of birds or the schooling of fish, applied here to schools of art.

We classify a sharp phase transition threshold for Friedman’s finite adjacent Ramsey theorem. We extend the method for showing this result to two previous classifications involving Ramsey theorem variants: the Paris–Harrington theorem and the Kanamori–McAloon theorem. We also provide tools to remove ad hoc arguments from the proofs of phase transition results as much as currently possible.

adjacent phrases, but they typically lack the ability to perform the kind of long-distance reorderings possible with syntax-based systems. In this paper, we present a novel hierarchical phrase reordering model aimed at improving non-local reorderings, which seamlessly integrates with a standard phrase-based system with little loss of computational efficiency. We show that this model can successfully handle the key examples often used to motivate syntax-based systems, such as the rotation of a prepositional phrase around a noun phrase. We (...) contrast our model with reordering models commonly used in phrase-based systems, and show that our approach provides statistically significant BLEU point gains for two language pairs: Chinese-English (+0.53 on MT05 and +0.71 on MT08) and Arabic-English (+0.55 on MT05).

The placenta invades the adjacent uterus and controls the maternal immune system, like a cancer invades surrounding organs and suppresses the local immune response. Intriguingly, placental and cancer cells are globally hypomethylated and share an epigenetic phenomenon that is not well understood – they fail to silence repetitive DNA sequences that are silenced in healthy somatic cells. In the placenta, hypomethylation of retrotransposons has facilitated the evolution of new genes essential for placental function. In cancer, hypomethylation is thought to (...) contribute to activation of oncogenes, genomic instability, and retrotransposon unsilencing; the latter, we postulate, is possibly the most important consequence. Activation of placental retrotransposon-derived genes in cancer underpins our hypothesis that hypomethylation of these genes drives cancer cell invasion. This alludes to an interesting paradox, that while placental retrotransposon-derived genes are essential for promoting early hominid life, the same genes promote disease-susceptibility and death through cancer. Placental and cancer cells fail to silence retrotransposons that are normally silenced in healthy tissues. This has created new genes that are essential for placental function, yet they are also expressed in cancer. We hypothesize that active retrotransposons are a double-edged sword, contributing both adaptive and deleterious functions to biology. (shrink)

This article describes an adjacency-pair organized course of action in the institutional context of customers calling an electronics repair facility to request the status of equipment they have previously sent in for repair. Relative to the majority of adjacency-pair sequences described in previous research, this course of action is rare in that it is essentially composed of three turns, including status solicitation, status response, and acceptance/rejection of status response. After defending this finding, we situate and discuss its significance relative to (...) prior research – in both ordinary and institutional contexts – on adjacency-pair sequence organization, including implications for sequence-based relevance rules, such as preference organization. Finally, we outline a possible general explanation for why some initiating actions set in motion essentially three-turn courses of action, and offer a candidate example in ordinary conversation.

What is it for something to have a nature? And what is it for law to have a nature? Analysis of the concept of law has often been taken to be a search for the essential features of law, but it is not clear that the nature of a phenomenon or artifact is better explained by its essential features than by its common ones. And it is not clear that necessary truths have more explanatory value than typical truths. Especially -- (...) but not necessarily - if we recognize the possibility that law is a cluster concept, the value of explaining the widespread but not strictly necessary features of law in explaining law itself becomes more apparent. The jurisprudential project of differentiating law from other social phenomena is an important one, but the distinction may be a fuzzy one and not susceptible either to sharp demarcation or to specification of essential features of law that will assist in differentiation. But if we inquire into what typically or usually or almost always characterizes law rather than what necessarily characterizes it, we may make genuine progress in distinguishing law from the social phenomena to which it is adjacent but with which it is not congruent.

Torres, Against Longtermism Philosophers,1 2 psychologists,3 4 politicians5 and even some tech billionaires6 have sounded the alarm about artificial intelligence (AI) and the dangers it may pose to the long-term future of humanity. (...) Some believe it poses an existential risk (X-Risk)7 to our species, potentially causing our extinction or bringing about the collapse of human civilisation as we know it. The above quote from philosopher Will MacAskill captures the key tenets of ‘longtermism’, an ethical standpoint that places the onus on current generations to prevent AI-related—and other—X-Risks for the sake of people living in the future.1 2 Developing from an adjacent social movement commonly associated with utilitarian philosophy, ‘effective altruism’, longtermism has amassed following of its own. Its supporters argue that preventing X-Risks is at least as morally significant as addressing current challenges like global poverty. However, critics are concerned that such a distant-future focus will sideline efforts to tackle the many pressing moral issues facing humanity now.8 9 Indeed, according to ‘strong’ longtermism,10 future needs arguably should take precedence over present ones. In essence, the claim is that there is greater expected utility to allocating available resources to prevent human extinction in the future than there is to focusing on present lives, since doing so stands to benefit the incalculably large number of people in later generations who will far outweigh existing populations.1 Taken to the extreme, this view suggests it would be morally permissible, or even required, to actively neglect, harm or destroy large swathes of humanity as ….

Dominant approaches to punishment tend to downplay the socio-emotional dimension of perpetrators. This attitude is inconsistent with the body of evidence from social and affective neuroscience and its adjacent disciplines on the crucial role of emotions and emotion-related skills coupled with positive social stimuli in promoting prosocial behavior. Through a literature review of these studies, this article explores and assesses the implications that greater consideration of emotional and social factors in sentencing and correctional practices might have for conventional punitive (...) approaches to crime. It argues that proper attention to these factors within the judgment of offending can challenge the tenets of dominant punitive ideologies and responses to crime. It further emphasizes the higher rationality and effectiveness of a paradigm of justice that aims for the social reintegration of perpetrators through a path to self-reform and change that is based on relational and inclusionary processes in the least confining environments possible to still ensure public safety. Hence, this article supports the pursuit of social rehabilitation as the ultimate goal of criminal justice. (shrink)

In this study, we use a conversation analysis framework to understand the systematic organization of interactions in Periscope live video streams, and its crucial features: the talking heads orientation for the video stream, in common with video-mediated communication; the expectation that the streamer should attend to all messages as much as possible; the ‘loose’ organization of viewers’ responses to streamers’ turn-at-talk, as in multi-party chats. We also identify a distinctive design for streamers’ responses to messages, the ‘read-aloud and respond’ (...) practice. These distinctive features are oriented to the highly asymmetrical communicative affordances of Periscope streams. Without precluding other forms of Periscope-based activities, this systematic organization of talk and messages, coupled with the affordances of the application, favors a basic mode of topic initiation resting on a typical and minimal adjacent pair: viewer’s noticing/streamers’ reading and responding. We argue that the particular salience of this organization of topic initiation may account for the emergence of the dominant kind of use for Periscope streams, that is, the online public exposure of youth to strangers in order to elicit some conversation.

On the one hand, it is often assumed that the Rubber Hand Illusion (RHI) is constrained by a structural body model so that one cannot implement supernumerary limbs. On the other hand, several recent studies reported illusory duplication of the right hand in subjects exposed to two adjacent rubber hands. The present study tested whether spatial constraints may affect the possibility of inducing the sense of ownership to two rubber hands located side by side to the left of the (...) subject's hand. We found that only the closest rubber hand appeared both objectively (proprioceptive drift) and subjectively (ownership rating) embodied. Crucially, synchronous touch of a second, but farther, rubber hand disrupted the objective measure of the RHI, but not the subjective one. We concluded that, in order to elicit a genuine RHI for multiple rubber hands, the two rubber hands must be at the same distance from the subject's hand/body. (shrink)

A close look at the Jesuit and Catholic recusant network that existed in the English midlands yields a pathway to the Chandos portrait of Shakespeare. The portrait is traced from the 3rd Duke of Chandos to Grafton Manor, seat of the Shrewsbury earls and a principal Jesuit center in the Jesuit district comprising Worcestershire and Warwickshire created in 1623. The article finds that during Shakespeare’s lifetime, Grafton Manor was owned by a Catholic recusant member of the Talbot family with ownership (...) ties to Welbeck Abbey located in the small township of Holbeck, Nottinghamshire; the parish of Holbeck included Welbeck Abbey and the adjacent Holbeck Hall, which was owned by the family that sheltered Edmund Campion and which served later as home to a major Jesuit library and as a shelter for Jesuits themselves. Keeping in mind Shakespeare’s indebtedness to North family writings as source material for the plays, the article finds that the provenance of an unpublished manuscript by George North which influenced Shakespeare, the manuscript’s content, and George North’s circle of acquaintances lead directly to Edmund Campion and the Pierrepont family that sheltered him before his execution by the crown in 1581. The article shows ties of the George North manuscript to Welbeck Abbey, ties of the North family to the nearby Wroxton Abbey, and possible ties of the alleged painter of the Chandos portrait to the North family at Wroxton Abbey. The article is written in response to the recently published book by Dennis McCarthy and June Schlueter on the discovery of an unpublished manuscript written by George North that they believe inspired Shakespeare. Further shown through parallel language and thought that George North in writing A Brief Discourse likely drew material from Campion’s Histories of Ireland, including material that eventually led to the episodes on Jack Cade in 2 Henry VI and the Merlin prophecy in King Lear—all before Campion’s Histories was absorbed by Holinshed’s Chronicles and ultimately absorbed by Shakespeare. The article, utilizing research by an eminent Jesuit historian showing a personally advantageous relationship between George North’s patron, the Queen’s favored Sir Christopher Hatton, and the Jesuit William Crichton, traces the Shakespeare First Folio discovered on the Isle of Bute in 2016 back through time to the North family and ultimately to the Jesuit Crichton. In consideration of a probable biographical relationship between Shakespeare and Hatton, another connection between Shakespeare and the Jesuits is revealed. Lastly, the article details textual support for the author’s previous research showing a relationship between the writings of the Jesuit John Floyd and the Shakespearean canon—hinting that Shakespeare assisted the Jesuits.

According to the most important objection to the existence of moral beauty, true judgements of moral beauty are not possible as moral judgements require being motivated to act in line with the moral judgement made, and judgements of beauty require not being motivated to act in any way. Here, I clarify the argument underlying the objection and demonstrate that it does not show that moral beauty does not exist. I present two responses: namely, that the beauty of moral beauty (...) does not lie in the moral goodness per se (the ‘adjacent properties’ response), and that only a dispositional motivation to act is required for the moral judgements that are typically made as part of judgements of moral beauty, whereas aesthetic judgements only rule out state motivations to act (the ‘equivocation of motivation required’ response). In addressing the objection, I show how moral beauty is consistent with disinterestedness, and so should be accepted more widely; also clarifying where the beauty in moral beauty resides, and how the moral–aesthetic distinction should be drawn.

In lieu of an abstract, here is a brief excerpt of the content:76. A REFUTATION OF HUME'S THEORY OF CAUSALITY1 Given Hume's conceptions of space and time, which I take to be fundamental to his theory of causality, it is not always possible to meet all of those conditions definitive of the cause-effect relation, i.e., those "general rules, by which we may know when" objects really 2 are "causes or effects to each other" (T. 173). To show this, it (...) will be necessary, first, to give a very brief exposition of Hume's conceptions of space and time, with regard chiefly to their implications for the nature of motion. Then, after briefly summarizing his views on the nature of the cause-effect relation, I shall proceed immediately to my objection. It should be noted first, however, that, if one instance of a cause-effect relation can be found to which Hume's analysis will not apply, that, presumably, would be sufficient to refute his theory. I shall not here repeat all of Hume's arguments for the indivisibility of space and time. Suffice it to say, he takes it to be fairly obvious that each must consist of a finite number of indivisible points or moments, each of which is distinct, and therefore separate, from every other, and, in the case of time, none of which ever "co-exist." Only one of his arguments for the indivisibility of space need concern us here. The argument is brief: The infinite divisibility of space implies that of time, as is evident from the nature of motion. If the latter, therefore, be impossible, the former must be equally so. (T. 31) The argument here seems, roughly, to be this: the motion of an object can be described only by giving its positions at various times (the nature of motion). If, therefore, an object, such as a ball moving along a line AB, can be assigned an infinite number of positions taken between A and B (the infinite divisibility of space), 77. the time taken to traverse AB must also be infinite, i.e., must consist of an infinite number of instants. But the finite time taken to traverse the distance AB is not infinitely divisible; therefore, neither is the line AB. This argument, of course, relies upon the assumption that, in traversing the line AB, the ball will occupy each of the points (whether finite or infinite) of which it consists. The argument can also be turned around so as to derive the finite divisibility of time from that of space. Here, too, it must be assumed that the ball occupies each of those instants which constitute the time taken to traverse the line AB. It thus seems clear that, on Hume's view, the ball's motion can be neither more nor less divisible than the space and time it takes to move. x In its motion from A to B, then, the ball will occupy first one, then another of the points lying between A and B until finally it has occupied them all and has moved from A to B. But, in saying that it will occupy first one and then another, we are saying nothing more than that it successively occupies a series of points, and, insofar as its occupation of these different points is successive, it takes time. We are in a position, then, to define motion (at least motion along a straight line) as "the successive occupation of adjacent, linearly ordered points or places." Now, this is very different from the usual conception of motion. The ball's motion between any two adjacent points is not a moving from one to the other. It is simply its being in the one place at one instant and its being in the other place at the next. It is not a continuous motion, but the occupation of discrete places at different times. It is, as it were, a series of instantaneous leaps. This interpretation, if it is accurate, may also serve to account for Hume's ill-understood propensity for 78. referring to cause and effect as objects rather than as events. Events must, on Hume's view of time at least, be essentially static. Unlike those... (shrink)

The spread of Islam from the Arabian Peninsula to the North Africa and al-Andalus in the west, to the Chinese borders and the Indian Subcontinent in the east, helped Muslims to establish close contact with many different cultures. One of the consequences of this is that both the increase in scientific accumulation and the emergence of new needs in military, financial and similar aspects accelerated the studies on geography. Islamic geographers of the first period, not only did they describe the (...) cities to which they travelled but also they depicted the cities about which they could collect data. These first works, which can be considered as a kind of written maps, have some common features, although they are written in different geographies and revealed by different schools. One of these common points is the terminology that they used in depictions of cities. This terminology suggests that there was a common city typology among Muslim geography scholars that stands out in the depiction of cities. In this study, particularly we will try to answer a number of questions such as what the concepts of authors are and what they mean and the relationship between these concepts by examining the uses of authors in their works.SummaryThe depictions of settlements which were designated as madīna in the works of the medieval Muslim geographers have some common characteristics. One of them is the terminology used by the authors in depictions of cities. In this study, particularly I tried to answer a number of questions such as what the concepts of authors are and what they mean and the relationship between these concepts by examining the uses of authors in their works. Then, a common city typology which is prominent in the depiction of cities among the Muslim geography scholars has been put forward. The structural elements that are considered to constitute this typology also revealed the topographic elements of a city at that time.The cities conquered by muslims had a great impact on the emergence of the terminology used by Muslim geographers in depicting cities. I can say that especially Persian influence; the cities in Iran, Khurāsān which were captured from the Sāsānians and Mā Warāʾ al-Nahr districts was effective. However, geography writers did not restrict using this terminology for only these regions, they also had continued to use in depiction of other regions such as North Africa and al-Andalus. This means that a common language and terminology emerged and started to be used.Geography authors point to five main elements that I have examined in separate titles while describing Islamic cities that they called "madīna". These are kuhandiz, shahristān, rabad, the part so-called “the adjacent agricultural fields / agricultural fields surrounded by wall” by us and the last part rustāq connected to main city center. Depending on ways of development of cities, these elements sometimes developed from inside to out, in other words from center to environment, sometimes surrounded by independent walls and sometimes adjacent to each other. However, a city did not have to have all these elements at the same time. This situation was totally related to development level of city, and the cities which had all these elements were the military, administrative and economically developed centers of the period. From the methodical point of view, it should be noted that the examples given in the study were selected from among the other cities in order to ensure that to understand the subject in best way and ensure that the silhouette on the city typology is seen better. Because it is possible to find examples of each element in all city depictions of Islamic geography writers. Kuhandiz, shahristān/madīna, and rustāq are the elements that can be seen in the pre-Islamic period. It is possible to think of the Islamic period as a period in which these words were conceptualized, new madīnas and rabads were formed, surrounded by walls and rabads were gradually transformed into madīnas. In geography texts, it is seen that there is a concept confusion between kuhandiž and buildings named qalʿa, ḥiṣār and ḥiṣn. However, as some writers hade tried to emphasize, "kuhandiz" had been using for these structures which were previously known as fortress (especially ḥiṣn or qalʿa) due to their proportion to shahristāns / madīnas of city centers, and were notably seen in the regions of Khurāsān and Mā Warāʾ al-Nahr. Kuhandižs represent the centers of pre-Islamic cities and were continued to be used for the same purpose in the early Islamic period. But, these old areas were gradually abandoned due to the development of new parts of settlement under Muslim administration. Shahristāns were residential areas where the majority of people lived. With the Islamic period, the word “shahristān” had been terminologically changed to “madīna” and use of this concept by scientific circles was gradually disappeared in time. At this point, it is one of the issues to be considered in the examination of geography works that the use of “madīna” in Arabic both for the concept of the city in which we examine the structural elements in this article, and for “shahristān” which is one of the elements of the city.As it is understood from the geographical texts, madīna was continued to be established by Muslims in cities for centuries. These are also examples of change in cities as a result of development and housing activities after the conquests. However, we don’t have much information in the geography works about the cities which had more than one shahristān /madīna before the inhabit of Muslims. As far as we can reach, the only example in our resources with multiple madīnas/shahristān belonging to the pre-Islamic period is Bukhara.As in the developed cities of the period such as Bukhara, Samarqand, Marw and Balkh, it is seen a generaly circular fortification wall which usually surrounded main center of cities including kuhandizs, madīnas/ shahristān and mostly later rabads. So, it is more appropriate to consider the areas between these walls and other parts of city (kuhandiz, shahristān/madīna, rabad) as an independent element because of the fact that they were lands with determined borders and were defined by separate concepts. I have used “adjacent agricultural area” for this element for now. Thus, this area constitutes one of the structural elements of the cities.Rustāqs were parts of Persian-Sāsānian urbanization and land administration, and had continued to be partially implemented during the Islamic period. They were the source of livelihood of the cities from foundation stage and were an indispensable tool of the society based on agriculture in that ages. Depending on size, the cities could have dozens of them. As can be seen in the case of Balkh, the rustāḳs especially connected to the big city centers were not composed of one or several villages. Moreover, these rustāqs could contain big settlements called madīna which were their centers. (shrink)

How people learn chunks or associations between adjacent items in sequences was modelled. Two previously successful models of how people learn artificial grammars were contrasted: the CCN, a network version of the competitive chunker of Servan‐Schreiber and Anderson [J. Exp. Psychol.: Learn. Mem. Cogn. 16 (1990) 592], which produces local and compositionally‐structured chunk representations acquired incrementally; and the simple recurrent network (SRN) of Elman [Cogn. Sci. 14 (1990) 179], which acquires distributed representations through error correction. The models' susceptibility to (...) two types of interference was determined: prediction conflicts, in which a given letter can predict two other letters that appear next with an unequal frequency; and retroactive interference, in which the prediction made by a letter changes in the second half of training. The predictions of the models were determined by exploring parameter space and seeing howdensely different regions of the space of possible experimental outcomes were populated by model outcomes. For both types of interference, human data fell squarely in regions characteristic of CCN performance but not characteristic of SRN performance. (shrink)

This paper is concerned with the moral justification for palliative sedation until death. Palliative sedation involves the intentional lowering of consciousness for the relief of untreatable symptoms. The paper focuses on the moral problems surrounding the intentional lowering of consciousness until death itself, rather than possible adjacent life-shortening effects. Starting from a Kantian perspective on virtue, it is shown that continuous deep sedation until death (CDS) does not conflict with the perfect duty of moral self-preservation because CDS does (...) not destroy capacities for agency. In addition, it is argued that CDS can frustrate the imperfect duty of self-cultivation by reducing consciousness permanently. Nevertheless, there are cases where CDS is morally acceptable, namely, cases where the agent has already permanently lost the possibility for free action in advance of sedation—for example, due to excruciating and ongoing pain. Because the latter can be difficult to diagnose properly, safeguards may be needed in order to prevent the application of CDS for the wrong reasons. (shrink)

This study on the cambium of Pinus sylvestris L. examines the intrusive growth of fusiform cambial initials and its possible contribution to the tangential and radial expansions of the cambial cylinder. The location and extent of intrusive growth of the fusiform initials were determined by microscopic observations and by mathematical modeling. In order to meet the required circumferential expansion of the cambial cylinder, the fusiform initials grow in groups by means of a symplastic rather than intrusive growth, leaving no (...) room for the assumption that intrusive growth of the initials takes place between radial walls and has a direct role in the increase of the cambial circumference. Therefore, it is postulated that the fusiform initials grow intrusively between the tangential walls of the neighboring initials and their immediate derivatives and not between the radial walls of the adjacent initials as per common belief.

Bailey Willis was the second major American geologist to undertake reconnaissance research in China--in the years 1903-04. Together with the stratigrapher Eliot Blackwelder, topographer Harvey Sargent, and guide Li Shan, he travelled first in Shandong Province, then from Peking to Xian, thence across the mountains into Sichuan, and then by river via the Yangzi Gorges to Shanghai. It was hoped that they would discover the primeval ancestor of trilobites in China, but the search proved unsuccessful. Willis's stratigraphic findings are described, (...) as are his structural interpretations of what he observed in China. His work in China gave rise to some unfounded speculations about the possible causes of lateral Earth movements, due to rocks of different densities being adjacent to one another in the Earth's crust. These ideas were followed by several other 'theories of the Earth' during Willis's later career, some of which were also probably related to his experiences in China. He seemingly practised the formulation of 'multiple working hypotheses'. The paper also discusses the influence of Willis's survey and stratigraphic work on the subsequent development of Chinese geology, with particular attention given to the various meanings of the term 'Sinian System'. Mention is made of later work in China on Lower Cambrian stratigraphy. (shrink)

This essay deals with metaphilosophical issues, i.e., different ways of “doing philosophy” and their possible applications for the formulation of a properly Brazilian philosophy. The arguments are drawn from questions that constitute the instigating and pertinent book by Gonçalo Palácios entitled De como fazer filosofia sem ser grego, estar morto ou ser gênio. In order to problematize the increasingly explored question of whether there is a Brazilian philosophy, firstly, I interact with some problems raised in the mentioned work, such (...) as academic philosophical practice, its attachment to the exegesis of works consecrated by tradition, and the consequent subdivision between history of philosophy and “philosophizing” through specific problems of national reality. Next, I articulate some elements that allow us to characterize a specifically Brazilian philosophy. To carry out this characterization, it is essential to critically articulate the relationship between philosophy teaching, in both school and academic level, with the philosophical tradition and its adjacent concepts.

In lieu of an abstract, here is a brief excerpt of the content:Generational Timescapes and Biotic Kinship in Omar El Akkad's American WarMichael Boyden (bio)References to future generations and how they might be impacted by decisions in the present abound in climate change communication—from scholarship dealing with the energy transition and climate control, to international agreements, and to public debates in civil society generally. One oft-noted reason why generational views are so frequently invoked in such contexts is that they serve (...) to make tangible otherwise intractable problems so vast in proportion that they tend to confound conventional ways of allocating ethical responsibilities and considerability. Conjuring the ways in which our choices and actions affect the quality of life of concrete individuals to whom we are connected by means of kinship ties awakens the present generation's sense of obligation toward the future.As a number of scholars have noted, however, generational views might also hamper our ability to work toward the kind of sustained transformation of the global economy that is required to ensure that Earth remains inhabitable in the future. In philosophy, political science, and adjacent fields, critiques of generational discourse have revolved around the limitations of governing models of ethics, as in discussions of Derek Parfit's "repugnant conclusion" (388) and in efforts to find new models of distributive justice that depart from utilitarian and contractualist approaches.1 In turn, scholars working in the interdisciplinary frameworks of critical posthumanism and queer feminism have attempted to rethink notions of kinship in ways that consider the ethical value of the nonhuman world and identities not grounded in biological kinship.2In this article, I argue that climate change fiction has the potential to [End Page 11] dramatize the conflicting valences of generational discourse—in ways that less layered, nonfictional narratives often fail to do—and in doing so points up the possibility of conceiving of environmental ethics in a different, less kinship-based fashion. Using Omar El Akkad's American War (2017) as my tutor text, I will argue that this novel presents a potent critique of the kind of generational discourse prevalent in debates about global warming today.My analysis is meant to show how El Akkad's novel, which adopts a markedly transcultural perspective that questions Western exceptionalism, brings out the limitations of—and visualizes alternatives to—the generational schemes through which the consequences of anthropogenic climate change are rendered intelligible. At the same time, I suggest, the novel offers pathways toward conceiving an ecocentric ethical framework that does not reproduce the anthropocentric assumptions of generational discourse.Climate Change and Generational DiscourseI start by defining more closely what we mean when we talk about generations. Political scientist Jonathan White has usefully distinguished three strands of generational views that tend to blend into each other in recent debates on climate change but that deserve to be kept analytically separate. The first of these is the genealogical understanding of generations, which pertains to familial "relations between individuals in their specificity" (765). This genealogical conception of generations has been with us for a long time. It is present, for instance, in biblical texts and classical historiography, which invoke family bonds to justify a given social order. Genealogical views are equally present, however, in modern evolutionary thinking and in the ordinary understanding of the generations of a family. The second strand identified by White is the sociological understanding of generations, which refers to "social groups defined by an apparent unity of ideas and attributes, irrespective of personal ties" (765). Sociological generations convey differences between young and old, or progressive and backward-looking forces, in times of societal transformation. Scholars trace this sociological conception of generations back to the nineteenth century, when the forces of industrialism and nationalism [End Page 12] magnified experiential divergences among social groups. Finally, White considers philosophical generations, which refer to "a society at different moments of existence" (765). Here, we may think of postrevolutionary contexts, when the clock is figuratively turned to zero and a new understanding of the social order emerges. Contrary to genealogical and sociological schemes, such philosophical generations are not grounded in a specific empirical formation; rather, they constitute a conceptual formula for organizing the (long-term) future.What makes generational...

In lieu of an abstract, here is a brief excerpt of the content:The Noble Impermanence of WaystationsMiriam Rowntree (bio)In the Austin-Bergstrom International Airport (ABIA), adjacent to Gate 14, a screen announces that boarding to Equestria is on time. The description below this announcement includes transport “through a portal to a parallel dimension” and a “harmonious sparkly” atmosphere. An attractive destination. Esquestria’s capital, Canterlot, offers castles, dragons, and, of course, ponies. As the heart of the My Little Pony universe, Canterlot (...) boasts a fantastical utopia. Gate ∞, as it is called (because its erstwhile home, Gate 13, is an unlucky number), imaginatively whisks weary travelers away to other fantastical destinations. Using a commonplace ticket machine or kiosk, travelers answer a series of whimsical questions and receive a ticket to a utopian destination that the machine has personally matched to the traveler for their mythical utopia. Doesn’t everyone want to go to lands of unicorns, ponies, or other such magic?The installation titled “Interimaginary Departures” draws upon 120 destinations drawn from various media, literature, and games, including Harry Potter, The Chronicles of Narnia, and The Wizard of Oz.1 Even the carpet is inspired by the rabbits of Watership Down. Artist Janet Zweig describes her art [End Page 570] installation as designed to “create generative situations in public settings” and Gate ∞ does invite possibility as it is situated in a portal askew to the portals of the real in the terminal. Gate ∞ boldly crosses a border wall at 7 degrees (fig. 1, p. 572), heightening the boundaries between the real and the unreal. The chairs, a trashcan, and a book are caught between worlds, a wall slicing through them. Although Zweig cites China Mieville’s The City and the City (2009) as inspiration for her art installation, for me, the juxtaposition of the “interimaginary” and the real calls to mind Olga Tokarczuk’s book Flights (2007).2 While Zweig’s kiosk personally recommends Equestria (fig. 2, p. 573), ABIA is itself merely a waystation on my own trip between Texas and Rome.Tom McAllister’s review of Flights in the Washington Post describes the book as “beautifully fragmented,” not unlike Zweig’s “Interimaginary Departures” which relies on structural fragmentation of a space to exemplify the interposition of the imaginary and the real.3 This book captivated me from the first strange narrative when I tried to read it several years ago. However, I found it difficult to finish the first time as the stories in each section (there are no chapters) moved rapidly from one place, person, idea, and time to the next. McAllister says that “the disconnectedness is part of the point; they are fragments of people’s lives, a patchwork of personal experience, secondhand observation and imagination. Each story appears, draws our attention and then fades as the narrator finds her way to a new hotel, a new airport.” Perhaps the disconnectedness is the point, but I have found that Tokarczuk also infuses the sections with a sense that “there exists in the world’s coordinate system a perfect point where time and space reach an agreement” (4). Like Zweig’s “Interimaginary Departures,” that agreement is found in movement and the waystations toward that right time and place.Destination: RomeI settle into my seat next to my two daughters. Our flight will land in Rome at 8:00 am tomorrow. I have prepared them for what this means for our bodies. Jet lag is no joke.

In lieu of an abstract, here is a brief excerpt of the content:Rhetoric, Reflection, and Emancipation: Farrell and Habermas on the Critical Studies of CommunicationG. Thomas GoodnightThere are moments in history that appear to be alive with emancipatory possibilities. Such were the years moving toward the end of the long twentieth century. In spring 1989, students protested the communist regime in China; the Tiananmen Square massacre initiated an episode of opposition and commenced China’s modern journey toward global reengagement. Revolutions in (...) Europe that autumn were more peaceful. On August 23 two million Estonian, Latvian, and Lithuanian citizens held hands and announced the Baltic Way as a departure from Soviet rule. Transitions rapidly followed in Hungary, Bulgaria, and East Germany, culminating in the Velvet Revolution where on November 17 student protests were beaten back by police in Prague only to be followed three days later by an assembly of 200,000 demanding the transfer of power from the Communist Party. On December 3, George Bush and Mikhail Gorbachev jointly announced an imminent end to the fifty-year-old Cold War. During this time of hopeful transition, two scholars were at work refiguring the philosophical mission of the Frankfurt school, transforming critique from its early totalizing posture into the critical study of communication.Thomas B. Farrell and Jürgen Habermas were trained in different traditions but adjacent disciplines, communication and sociology. Their works [End Page 421] share a commitment to philosophical inquiry directed toward critique and understanding the cultural, social, and linguistic constitution of communication. As a rhetorician and as a philosopher, these scholars share an evident passion for scholarly argument and for engagement with the controversies of public culture. In different ways, both were at work during the portentous years of transition from the Cold War to new democracies and incipient globalization. Each constructed a guarded program of hope in the possibilities of communicative reflection and reasoning. In the post-World War II era, such a broad, positive vision took long to develop. After the brutal realities of the Holocaust became publicly known in the late 1940s, “the generous faith in rationality and the possibilities of human progress which underlay much of earlier historical thought seems discredited today” (Katznelson 2003, 2). The Enlightenment possibilities for reason had been invested in the technical efficiency of modern institutions that produced the capacity to kill systematically without constraints. Ira Katznelson points to a generation of scholars—including individuals at Chicago, Columbia, the New School, and others—who began in the 1950s to engage in a project that would “shade the Enlightenment’s philosophical anthropology, thicken its defenses against evil, deepen its capacity to reason, and restore” an Enlightenment more critical and less susceptible to co-optation by the excesses of nationalism, ideology, and evil (2003, 2). The work of Farrell and Habermas belongs to the extended post-Holocaust moment, where the possibilities of reflective reason in ethical and moral deliberations were set carefully on a road to personal and collective emancipation.Max Horkheimer saw in the modern, postwar welfare state little reason for optimism. Writing in 1946 at the beginning of the Cold War, he concluded: “Language has been reduced to just another tool in the gigantic apparatus of production in modern society” (1974, 22). “Salestalk” by “the surrogates of culture” creates an “illusory triumph of democratic progress that consumes the intellectual substance on which democracy has lived” (Horkheimer 1974, 31). Scientifically engineered propaganda renders public opinion as “a substitute for reason.” With such tools, the forces of barbarism are always waiting in the wings to seize power. Early on, Habermas shared these views. His thesis, in The Structural Transformation of the Public Sphere (1989a), tracks the opening possibilities of communicative reasoning in the liminal spaces of eighteenth-century coffeehouses where frank talk replaced hierarchically driven politeness, the development of these talks into the practices of deliberative democracy, and the decline of deliberative democracy with the union of the state and mass media in producing spectacles in [End Page 422] support of rituals of legitimation. Habermas broke with Horkheimer over the dissertation, however. A thesis of decline, by itself, leaves open only the route of totalizing critique. While never far from critique of institutional practices, Habermas spent his career in opening a positive... (shrink)

Many quantitative scales are constructed using cutoffs on a continuum with scores assigned to the cutoffs. This paper develops a framework for using or constructing such scales from a decision-making standpoint. It addresses questions such as: How many distinct thresholds or cutoffs on a scale (i.e., what levels of granularity) are useful for a rational agent? Where should these thresholds be placed given a rational agent’s preferences and risk-orientation? Do scale score assignments have any bearing on decision-making and if so, (...) how should scores be assigned? Given two possible states of nature , an ordered collection of alternatives from which one is to be selected depending on the probability that A is the case, a simple expected utility condition stipulates when adjacent alternatives are distinguishable and determines the threshold odds separating them. Threshold odds and utilities are mapped onto scale scores via a simple distance model. The placement of the thresholds reflects relative concern over decisional consequences given A versus consequences given ∼ A. Likewise, it is shown that scale scores reflect risk-aversion or risk-seeking not only with respect to A versus ∼ A but also with respect to the rank of the R j . Connections are drawn between this framework and rank-dependent expected utility (RDEU) theory. Implications are adumbrated for both machine and human decision-making. (shrink)

Perceptual learning involves an improvement in perceptual judgment with practice, which is often specific to stimulus or task factors. Perceptual learning has been shown on a range of visual tasks but very little research has explored chromatic perceptual learning. Here, we use two low level perceptual threshold tasks and a supra-threshold target detection task to assess chromatic perceptual learning and category effects. Experiment 1 investigates whether chromatic thresholds reduce as a result of training and at what level of analysis learning (...) effects occur. Experiment 2 explores the effect of category training on chromatic thresholds, whether training of this nature is category specific and whether it can induce categorical responding. Experiment 3 investigates the effect of category training on a higher level, lateralized target detection task, previously found to be sensitive to category effects. The findings indicate that performance on a perceptual threshold task improves following training but improvements do not transfer across retinal location or hue. Therefore, chromatic perceptual learning is category specific and can occur at relatively early stages of visual analysis. Additionally, category training does not induce category effects on a low level perceptual threshold task, as indicated by comparable discrimination thresholds at the newly learned hue boundary and adjacent test points. However, category training does induce category effects on a supra-threshold target detection task. Whilst chromatic perceptual learning is possible, learnt category effects appear to be a product of left hemisphere processing, and may require the input of higher level linguistic coding processes in order to manifest.

It is a widely accepted thesis in the cognitive sciences and in naturalistic philosophy of mind that the contents of at least some mental representations are innate. A question that has popped up in discussions concerning innate mental representations is this. Are externalist theories of mental content applicable to the content of innate representations? Views on the matter vary and sometimes conflict. To date, there has been no comprehensive assessment of the relationship between content externalism and content innateness. The aim (...) of this paper is to provide such an assessment. I focus on the notions of innateness that are employed in innateness hypotheses within the cognitive sciences and adjacent fields of philosophy, and on causal externalist theories of content. I distinguish between three accounts of what being innate might amount to in innateness hypotheses within the cognitive sciences, and between three types of causal externalism. I explain what the possibility of innate externalistically individuated representations depends upon given all nine combinations. I explain why causal externalism can be true of innate mental representations, given but one of these combinations. (shrink)

In view of the aging and dejuvenation of the working population and the expected shortages in employees’ skills in the future, it is of utmost importance to focus on older workers’ employability in order to prolong their working life until, or even beyond, their official retirement age. The primary aim of the current study was to examine the relationship between older workers’ employability (self-)perceptions and their intention to continue working until their official retirement age. In addition, we studied the role (...) of potential antecedents of their perceived employability at three different levels: training and education in current expertise area as well as in an adjacent expertise area (individual level factor), learning value of the job (job level factor), and organizational career management practices (organizational level factor). Data were collected by means of e-questionnaires that were distributed among two groups of Dutch older (45-plus) white collar workers. The samples consisted of 223 employees of an insurance company, and 325 university workers, respectively. Our research model was tested separately in each sample using Structural Equation Modeling. We controlled for effects of respondents’ (self-)perceived health and (self-)perceived financial situation. Similar results were found for both samples. First, the relationship of perceived employability with the intention to continue working until one’s retirement age was positive, whereas the relationship between a perceived good financial situation with the intention to continue working until one’s retirement age was negative. Secondly, as regards the potential antecedents, results showed that the learning value of the job was positively related to perceived employability. In addition, an employee’s perception of good health is a relevant correlate of perceived employability. So, whereas perceived employability contributes to the intention to continue working until one’s retirement age, a good financial situation is a push factor to retire early. In order to promote the labor participation of older workers, this study indicates that organizations should focus on the learning possibilities that are inherent to one’s job rather than on providing additional training or career management. Further research is needed to test the generalizability of our results to other samples. (shrink)

There is a growing recognition, stemming from work with both vertebrates and invertebrates, that the capacity for neuronal regeneration is critically dependent on the local microenvironment. That environment is largely created by the non‐neuronal elements of the nervous system, the neuroglia. Therefore an understanding of how glial cells respond to injury is crucial to understanding neuronal regeneration. Here we examine the process of repair in a relatively simple nervous system, that of the insect, in which it is possible to (...) define precisely the cellular events of the repair process. This repair is rapid and well organised; it involves the recruitment of blood cells, the division of endogenous glial elements and, possibly, migration from pre‐existing glial pools in adjacent ganglia. There are clear parallels between the events of repair and those of normal glial development. It seems likely that the ability of the insect central nervous system to repair resides in the retention of developmental capacities throughout its life and that damage results in the activation of this potential.

Place mouse over image continent. 2.1 (2012): 36–39. From an ethical and political perspective, people and property can hardly be separated. Indeed, the modern political subject – that is, the individual, the person, the self, the autonomous actor, the rational self-interest maximizer, etc. – has taken shape in and through the elaboration, institutionalization, and enactment of that which rightfully belongs to it. This thread can be traced back perhaps most directly to Locke’s notion that the origin of the political state (...) occurs when people rise above the state of nature by ceding the power to prosecute offenses. The rule of law begins then with a defense of the right to property. People become subjects by adhering to the social contract, which they do by deferring the defense of their own property to the state. In this light, the response of the United States federal government to the financial crisis of 2008 appears to many as a breach of the social contract. The chant “banks got bailed out, we got sold out” states the claim plainly. Why exactly did some subjects (e.g., the banks) have their property defended by the state (i.e., through the variety of programs including TARP, the discount window at the US Federal Reserve, etc.), when other subjects (e.g., homeowners) found themselves without protection of their property rights, forced to default on mortgage debts and face dispossession? Even if the rhetoric about “too big to fail” can be believed, and the collapse of the financial system would lead to negative consequences for people who had little or no connection to the activities that brought it about, such consequences need not call into question the notion that everyone stands equally before the law. To occupy, then, appears as a form of civil disobedience, an intentional, retaliatory breach of the social contract by those who feel that they have lost the support of the state to which they ceded their power as sovereign agents. The visible and the invisible The violation of property rights of people who have recognition, protection and power under the law destabilizes their very status as citizens and tests the limit of democracy. Does the financial system force the dematerialized victimization of individuals? Do people become numbers, or worse still, percentages of unemployed, tranches of defaulted mortgages and foreclosures? Are they perhaps instead disenfranchised prospectively from the privileged position occupied by virtual entities and actors such as those involved in the derivatives markets, always already exiled back into the physical, visible realm? The line of conflict appears to be drawn between invisibility/absence/deferral and visibility/presence/realization. The demonstrators occupy an excess property of those subjects, namely, the banks and financial elite, who did receive recognition and protection under the law. By domesticating this excess property, rendering its invisibility visible within the political economy, the protesters raise a new form of threat to the hegemonic order. To occupy, then, involves a rejection of the order under which the “99%” have been subjected to erasure. The occupation seeks creatively to establish a new means of communication and law for its subjects. In the face of an existing power structure that is increasingly disenfranchising the majority of people while consolidating nodes of power and influence, the “occupation”, or the work of the Occupy movement, involves seizing a space that refuses the rules of the existing, allegedly corrupt sovereign state. This refusal of governance extends even to include a steadfast refusal to articulate a strategy, to formulate a list of demands, to converse with the sovereign power on the grounds of its own conventions, to put forth a leader, to resolve the ambiguity of the movement into a discreet identity, face, or voice. Do these tactics provide a resolution to the problem that was its genesis? Not in such a direct and easily resolved manner, but it remains difficult to imagine a direct and simple resolution to the problematic of the breach of the social contract. The ambiguity of the situation has generated significant interest within the broader populace, though many people sympathetic to the cause appear to be frustrated because the movement has not simply put forward a short list of concrete demands, or even a set of leaders and spokespeople, much less a resolution. And yet, this lack of coherence appears as a resolution of a problem generic to protest movements in the past, where individual leaders can be removed or discredited, and lists of demands can be co-opted by others holding more political power. Meanwhile, the ambiguity has compelled imitations on a global scale, with the Occupy Wall Street participants consciously taking actions that can be replicated by anyone anywhere without significant cost. These actions have taken place not in a peripheral location such as a parking lot in New Jersey, but instead close to the centers of power and governance, adjacent to Wall Street, close to the White House, on college campuses, etc. This spontaneous archipelago of protests becomes an irritant, a negation of the accepted order of protests, but when the protesters themselves move outside of their encampments, they are escorted by the police, constantly monitored and maintained so that a permanent state of paranoid persecution takes hold. To occupy, occupying, occupation – these actions involve a variable degree of danger – are you willing to step into a different space, where the rule of law is unclear and evolving? Are you presenting yourself as a representative of the majority, the 99%? Who has a sense of belonging to the 99%? This previously invisible population becomes a focal point of political power, garners increasing public support, infects the public dialogue. The government recognizes this population by forcing it from the occupied space, removing the element of possession of property. It is at this point of conflict, in the struggle to hold the physical property, where the greatest friction and violence occurs. Scaling the rule of law While occupied, the property calls for a redress of grievances, a restoration of the rule of law. The Occupy movement does not select and put forward individuals or leaders, it puts forward places – the occupied property represents the point of conflict, not the individual. And it is this very property that the government then tries to reclaim. The movement remains faceless, anonymous, uncounted, or rather counted only as a mass, the self-labeled mass of 99%. These spaces are like refugee camps or favelas, but constructed to unite the political life and private life of the protesters. This objective is presented as a tactical necessity, as all other means of protest and communication have failed, leaving only the option of seizing, holding, occupying a property. But to what end, exactly? Can anyone deliberately return to the prior social contract, embrace, affirm, and govern in strict accordance with the earlier relationship to property, following the logic of Locke’s arguments? In this respect, the contemporary crisis indicates a new, transitional phase in the way that property operates, or rather, in the balance between real and virtual value. The roots of the crisis lay in the massive overvaluation of property caused by lax lending practices, as more people were encouraged to borrow more money, which drove up the prices of property. At the same time, these individual properties, these mortgages for homes actual families lived in and worked to support, were bundled into securities that could be bought, sold, and speculated on. The reduction of a physical house or piece of real estate to an almost incalculably small element in an investment vehicle appears as a scaling of the hedge that radically diminishes the value of any individually owned property. Moreover, a number of recently-innovated financial products allow investors to hedge in new ways, to deliberately spread risk around a portfolio in hopes of bringing returns even when the individual mortgage defaults. At the level of the ‘free’ market, these virtual negative valuations are designed to balance the physical positive valuation, though many of the biggest lenders are now being investigated for controlling both sides of this valuation, the positive and the negative, to facilitate both the creation and failure of the investments and to profit from both. The ability to benefit from both the negative and positive value of an investment is a result of a technologically enabled capacity to operate within a complex field. These layered and scaled investment vehicles and the simultaneous negation of their value together represent a commingling of the virtual and physical existence that is both complex and multiple. The valuation of a virtual property has tremendous power to change the valuation of the physical - either injecting it with or depriving it of funds, pumping in or draining life and energy. This situation has roots of its own – the notion of property advanced e.g., throughout the enclosure movement in Britain was, from the outset, an imposition of virtuality (i.e., the concept of law, the institutions associated with ownership, etc.) on the physical reality of land. 1 The difference today is that technological trading platforms combined with innovations within the financial services industry have enabled the reduction of each individual property receiving or losing value in scale to an almost atomic level. In turn, the number of properties held simultaneously and valued as a massive, multiple wholes – i.e., the derivatives market in mortgage-backed securities – is a new phenomenon made possible through the application of similar technologies and institutional structures. And those actors who can trade in these layers of complexity can then profit from the new phase of disassociation of the virtual and the physical – unconcerned with and operating at such a virtual distance from the individual residing physically on a particular piece of real estate that they no longer feel the tug of the physical tying them back to the physical, operating literally as in a video game, in a virtually distanced world. What can or should be done about this situation? Answers lie outside the scope of this current essay, but merit consideration in the near future… NOTE 1) Hernando de Soto has emphasized this dimension by empirically demonstrating its non-existence in many countries in The Mystery of Capital.

The focus of this chapter is the rise of investigations in philosophical aesthetics in the mid-1950s and continuing through to the mid-1960s. This salient issue had to do with the foundations of philosophical aesthetics in the context of the Marxist-Leninist worldview. That this became an issue was due in large part to the appearance, in 1956, of the first Russian translation of Marx’s Economic and Philosophical Manuscripts of 1844. Marx’s emphasis in these writings on the self-constituting, transformative potential of labor (...) suggested possibilities for an aesthetic that did not sit comfortably with the dogmatic principles of dialectical and historical materialism. In effect, the foundational question for a Soviet aesthetics went to the heart of Marxism-Leninism: could young Marx’s anthropocentrism be reconciled with the established Soviet doctrine beholden to, on the one hand, Engels’ metaphysics of “matter-in-motion” and, on the other hand, Lenin’s copy theory of knowledge? Among the aestheticians, the issue surfaced in a debate about the nature of beauty: is beauty relative to man or is it an objectively cognizable material property? To the degree that the parties to this debate addressed the underlying issue, they tended to remain ambivalent toward the result that neither side—those favoring creative expression versus the defenders of objective beauty—simply conceded nor rejected the views of the other. As I argue, a systematic philosophical aesthetics within the scope of Soviet philosophy never saw the light of day. By the mid-1960s, research was ramifying into a variety of adjacent considerations, for example, value theory, theories of culture and cultural artifacts, the history of aesthetic categories, the social and pedagogical functions of art, art and morality in relation to the “socialist way of life,” art in the era of the “scientific-technological revolution,” and so on—of which only some recalled the spirit, rarely the letter, of the initial “aesthetics” discussion.

In the intelligent transportation system, the license information can be automatically recognized by the computer and the vehicle can be tracked. Red light running, illegal change of lanes, vehicle retrograde, and other illegal driving events are reasonably recorded. This is undoubtedly an effective help for the traffic police to relieve the huge work pressure. However, in China, a considerable number of vehicle tracking methods have certain limitations in resisting complex external environmental influences. The external environmental factors include but not limited (...) to variable factors such as camera movement, jitter, and severe rain and snow. These factors cannot be controlled well, so the tracking accuracy is greatly reduced. In regard to this, this paper proposes an optimization method for moving vehicle tracking based on SPF. First, according to the size of the overlapping area of the motion area between the two images, the researcher can construct and simplify the vertex adjacency matrix that reflects the characteristics of the undirected bipartite graph. Then according to the corresponding relationship between the vertex adjacency matrix and the regional behavior and vehicle behavior, the researcher completes the regional behavior analysis and vehicle behavior analysis. On this basis, a particle filter vehicle tracking algorithm based on segmentation compensation is introduced, and the vector sum of the tracked segmentation area is used as the final position of the target vehicle. In this way, as many scattered particles fall on the target area as possible, which will greatly improve the efficiency of particle utilization, enhance tracking accuracy, and avoid the problem of tracking failure caused by too fast vehicle movement. Through experimental simulation, it can be seen that the method proposed in this paper can greatly enhance the vehicle tracking ability when tracking vehicles in “complex environments.”. (shrink)

According to the most important objection to the existence of moral beauty, true judgements of moral beauty are not possible as moral judgements require being motivated to act in line with the moral judgement made, and judgements of beauty require not being motivated to act in any way. Here, I clarify the argument underlying the objection and demonstrate that it does not show that moral beauty does not exist. I present two responses: namely, that the beauty of moral beauty (...) does not lie in the moral goodness per se (the ‘adjacent properties’ response), and that only a dispositional motivation to act is required for the moral judgements that are typically made as part of judgements of moral beauty, whereas aesthetic judgements only rule out state motivations to act (the ‘equivocation of motivation required’ response). In addressing the objection, I show how moral beauty is consistent with disinterestedness, and so should be accepted more widely; also clarifying where the beauty in moral beauty resides, and how the moral–aesthetic distinction should be drawn.

Given a quantum system with a very large number of degrees of freedom and a preferred tensor product factorization of the Hilbert space we describe how it can be approximated with a very low-dimensional field theory with geometric degrees of freedom. The geometric approximation procedure consists of three steps. The first step is to construct weighted graphs with vertices representing subsystems and edges representing mutual information between subsystems. The second step is to deform the adjacency matrices of the information graphs (...) to that of a low-dimensional lattice using the graph flow equations introduced in the paper. The third step is to define an emergent metric and to derive an effective description of the metric and possibly other degrees of freedom. To illustrate the procedure we analyze two information graph flows with geometric attractors and metric perturbations obeying a geometric flow equation. Our analysis also suggests a possible approach to quantum gravity in which the geometry emerges directly from a quantum state due to the flow of the information graphs. (shrink)

This commentary focuses on the two basic assumptions of the E-Z Reader model, discussing the possibility that adjacent words in reading may be processed in parallel rather than serially, and presenting evidence against a cognitive control of eye guidance in reading.

There is a plethora of literature addressing Martin Heidegger’s connection to, and influence upon environmental philosophy, deep ecology, and the corollary debate over whether animals deserve moral consideration.1 Yet, for the most part, scholars have either inadvertently or deliberately refrained from reopening these topics within the adjacent arena of the law or legality. There may be prima facie good reasons for this avoidance due to 1) the obvious disjunction between Heidegger’s thinking and the modern, legalistic tradition around which much (...) of the current debate over the possibility of ascribing “rights” to animals revolves (Radloff 2007, 257–69;..

Continuous subgraph matching problem on dynamic graph has become a popular research topic in the field of graph analysis, which has a wide range of applications including information retrieval and community detection. Specifically, given a query graph q, an initial graph G 0, and a graph update stream △ G i, the problem of continuous subgraph matching is to sequentially conduct all possible isomorphic subgraphs covering △ G i of q on G i. Since knowledge graph is a directed (...) labeled multigraph having multiple edges between a pair of vertices, it brings new challenges for the problem focusing on dynamic knowledge graph. One challenge is that the multigraph characteristic of knowledge graph intensifies the complexity of candidate calculation, which is the combination of complex topological and attributed structures. Another challenge is that the isomorphic subgraphs covering a given region are conducted on a huge search space of seed candidates, which causes a lot of time consumption for searching the unpromising candidates. To address these challenges, a method of subgraph-indexed sequential subdivision is proposed to accelerating the continuous subgraph matching on dynamic knowledge graph. Firstly, a flow graph index is proposed to arrange the search space of seed candidates in topological knowledge graph and an adjacent index is designed to accelerate the identification of candidate activation states in attributed knowledge graph. Secondly, the sequential subdivision of flow graph index and the transition state model are employed to incrementally conduct subgraph matching and maintain the regional influence of changed candidates, respectively. Finally, extensive empirical studies on real and synthetic graphs demonstrate that our techniques outperform the state-of-the-art algorithms. (shrink)

Pros and Cons: A Debaters Handbook offers a unique and invaluable guide to current controversies, providing material for debate on a wide range of topics. Arguments for and against each subject appear in adjacent columns for easy comparison, and related topics and suggestions for possible motions are listed at the end of each entry. Since its publication in 1896 the handbook has been regularly updated and this eighteenth edition includes new issues such as censorship of the internet, genetic (...) engineering and the legalisation of prostitution. The introductory essay describes debating technique, covering the rules, structure and type of debate, and offering tips on how to become a successful speaker. The book is then divided into eight thematic sections, where specific subjects are covered individually. (shrink)

Silence has gained a prominent role in the field of psychotherapy because of its potential to facilitate a plethora of therapeutically beneficial processes within patients’ inner dynamics. This study examined the phenomenon from a conversation analytical perspective in order to investigate how silence emerges as an interactional accomplishment and how it attains interactional meaning by the speakers’ adjacent turns. We restricted our attention to one particular sequential context in which a patient’s turn comes to a point of possible (...) completion and receives a continuer by the therapist upon which a substantial silence follows. The data collection consisted of 74 instances of such post-continuer silences. The analysis revealed that silence can retroactively become part of a topic closure sequence, can become shaped as an intra-topic silence, and can be explicitly characterized as an activity in itself that is relevant for the therapy in process. Only in this last case, the absence of talk is actually treated as disruptive to the ongoing talk. Although silence is often seen as a therapeutic instrument that can be implemented intentionally and purposefully, our analysis demonstrated how it is co-constructed by speakers and indexically obtains meaning by adjacent turns of talk. In the ensuing turns, silence indeed shows to facilitate access to the patient’s subjective experience at unconscious levels. (shrink)

Located in Kleinbasel close to the Rhine, the Kaskadenkondensator is a place of mediation and experimental, research-and process-based art production with a focus on performance and performative expression. The gallery, founded in 1994, and located on the third floor of the former Sudhaus Warteck Brewery (hence cascade condenser), seeks to develop interactions between artists, theorists and audiences. Eight, maybe, nine or ten 40 litre bags of potting compost lie strewn about the floor of a high-ceilinged white washed hall. Dumped, split (...) open, the soil mixed with iridescent specks of green, blue and red glitter. On the walls hang large black and white photographic images—negative and positive prints barely clean, hardly sharp, scavenged from the world and presented half processed. On a third wall, hangs a framed golden and charcoal surface. Finally, a huge stain of black dye runs down a wall that descends into a sunken quarter of the Kaskadenkondensator gallery space. The results of a collaboration between Oliver Minder and Walter Derungs reflect on themes addressed in the recent Aesthetics in the 21st Century conference held by the department of English, University of Basel. In particular, the joint show questions how an aesthetic experience may be other than a human-world interaction, hinting at the withdrawal and veiling that objects perform, while demanding that different works engage with each other and play out this game under the non-supervisory eyes of a human audience. Things here are becoming—sometimes it’s a movement towards a more complete ontic whole in a projection of finality, other times it’s a dispersal, an atrophy to rather disarrayed entities. Yet, in the moment and place in which the objects are, we take them as here and now. Let’s get to the material of the stuff that Minder and Derungs have assembled. Oliver Minder employs organic materials—potting earth, cuttlefish ink secretion, rice, and insects; yet his works hardly seem natural in the sense of a harmonic relation between material and the form they are constrained into, the objects they are compelled to occupy. For the substrates on, through, or within which these natural materials are mediated are harshly inorganic substances—Plexiglas, safety glass, acrylic resin, boat varnish, spray paint. Minder, thus, generates a conflict within the materiality of his work between two polar opposites—from the human perspective—in the contiguity of materials engaging with each other in a thrown together formation that nonetheless appears to keep the materials and the objects they make in happy accidental relation to each other. Let me expand a little: on the one hand, the things Minder makes query our belief in substance as belonging in a particular domain, an environment suited to precisely that stuff. We are focused on thinking categorically where things belong, both in terms of natural place and natural relations they might extend to each other. Hence, we are driven to think of environment and order. On the other hand, while extracting things from their conventional place and arranging them within awkward constellations that we as observers feel isn’t quite right, Minder manages to persuade the viewer that the materials are nonetheless “doing alright.” So, simultaneous to our awareness of the appropriateness of the world according to our global notions of accord and uniformity, we are forced to accept the local discrepancies of disassociation, inappropriateness and misplacement. The tension between these two vectors generates a vacillation that intensifies Minder’s work. In the Kaskadenkondensator works, then, it is vital to first consider the material of Minder’s works: potting compost—what is it doing here in the first place?—seems to enjoy being “polluted” by sparkly glitter. Glitter has a long history, used in cosmetics by the Egyptians, and in cave paintings, too, earlier made of beetle shells and mica, nowadays glitter is made of plastic cut to minute sizes down to 50 microns. So what’s the point here? Well shiny bits of dust-like material are actually generated from ultra-thin plastic sheets and are normally cut into shapes that fit contiguously on a two-dimensional surface: squares, triangles, hexagons etc. What then appears to be totally random, chaotic decoration, is actually an array of extremely regular identifiable objects. 1 Of course scale has a role to play here. The minuteness of the dimensions means the regularity is beyond our recognition—all we see are the twinkling surfaces of the multi-coloured grains of plastic. In contrast, potting compost, which appears to be unary in its dull unresponsive lumpen disposition, is in fact an amalgam of a variety of organic and inorganic materials: peat, bark, mushroom compost, and sand and perlite, and should perhaps be more proactively exciting to the viewer because of this complexity. Yes; we can (if we care to) identify different textures, different sizes in the mixture of the medium, but I claim that we tend to treat this organic/inorganic assemblage as just a simple substance. Further and crucially important to our consideration here is that the medium is partially contained, but also partially spilling from the split plastic bags in which it is sold in garden centres. That the compost spills out gives it a movement suggesting life; that the bags are cast here and there in a random fashion by Oliver Minder, lying like discarded carcasses, hacked torsos, dismembered bodies, suggests a horrific murder scene, a Tatort. 2 The glitter flourishes in the medium, lies happy and decorative; that is simply what it does, how it is—always already broken, made-for-scattering, designed to be incomplete; the taken-to-be-natural compost, in contrast, cannot rest content but is forced to speak to us metaphorically in its abject overflowing of violence and rupture. While Oliver Minder’s elements in the installation direct our attention to material, Walter Derungs’ works raise questions around seeing and making in photography. There is a simultaneous flicker between the materials and their use in the production of a sense making representation, on the one hand, and on the other the very notion of what is worthy of picturing, framing, representing on the other. Derungs' images are of non-places. Ranging from archaic decaying monster buildings, buildings that have gone far beyond the ravages of a time that we can safely associate with the genteel preservation of a Bernd and Hill Belcher post-industrial decline, to the background “noise” of an urban world that is falling apart, and to which we most of the time seem to pay little attention, and habitually just pass by. In this respect, their non-ness differs somewhat from the conventional association of the term with Marc Augé 3 , where emphasis is on the specifics (if we do care to examine them for their non-placedness) of the spatial or place containment in which movement between multimodal coordinates occurs in supermodern late capitalist post-urban spaces. In other words, we might be in an Augéian non-place and (not) experience—be impervious to—that environment, or we might in Derungs’ manner look out from such a position at the “scenery” around us. I claim scenery, as this is what Derungs seems to do with his partial photography—construct a very purposefully articulated, symmetric, flat world of image. Mostly depopulated, his images construct a space in which the direction of time is uncertain: are these partial structures falling apart, or perhaps terminated in a never-to-be-completed state, or are they a few steps from final completion? Temporal and spatial dimensions figure large in Derungs’ image-making: his world, and perhaps this is in fact the only way for it to be registered photographically, is already image before it is photographed. A key combination of images in this show is a matrix of six black and white negative prints measuring 300 x 215 cm that form the image of a semi-derelict (or is it yet incomplete) church, and adjacent on a perpendicular wall, a single black and white positive print 150 x 250 cm of two bricked-up windows of a late-Victorian industrial building. What are we led to believe that we see here? In the negative print, the conditions of perception 4 are sufficiently reproduced for us to recognise the structure of the building, to distinguish ground and form, to relate some partial elements of narrative, and to recognize symbols such as the alter cross and figure of Christ, a looming crane, a traffic cone, and banks of tiered seating. We piece the image together both from the individual forms which we recognize despite the tonal reversal, and we piece the six prints together as a whole, the matrix of lines between them emphasizing our purview onto the world. While we recognise the forms at work in the image and might possibly relate the negative reversals to other figurations such as Vera Lutter’s camera obscura exposures, we cannot but avoid seeing the partialness of the image in the sponge marks of the developer that was spread by hand across the prints. 5 Derungs’ thus intervenes with our usual conception of photography as the mimetic realist vehicle sine qua non , by exposing the viewer to tonal reversal and incomplete or over developed areas of the print. We thus confront both the idiom of such image making and its raw (chemical) materiality at once in the simultaneity of the recognition of what the image pictures and the recognition that it is in the act of picturing. The church image, taken from the series “BW Negativs 2011,” thus orients us towards how we see things in the world via photographs. The single image of the bricked-up wall presents us with a completely different visuality that relates to a faciality 6 which we cannot easily escape from. We look, or rather try to look with no success, through the face of the windows, through the classic Albertian screen 7 which has already been given to us in the church matrix beside. Yet although we should be able to make more of these concealed windows because they are a positive print, because they are complete, because they approach us on a more realistic scale, reproduced at life size, we cannot. The objects pictured here withdraw from us; furthermore, they merely mock our blindness at not seeing how we look. Blocked up with quite a hint of paned glass behind, one window is blanked out with a white blind, the other simply blankly dark. The apertures look like eyes with teeth in them, or a Dogon mask, or even Man Ray’s Noire et Blanche (1926) if we want to get really perverse. The height of elegant modernist chauvinist beauty thrown against the vacuity of post-industrial decline. Derungs thus catapults us consciously into a world enfolded with and through images, but in such a way that the images themselves become objects that stand resistant to us, impervious to our gaze, indifferent. We—and indeed they—do not attempt to reach out to a real that is beyond, rather the images play in a world that is just theirs, and we can only enter that world if we too submit to their regime: tonal reversal, segmented, partial, inadequate, still, wrenched out of time. In contemplation, in the flood of the image “falling” off the wall, we too become image-object. Perhaps enough has now been said about the works, yet enough can never really be said, we know the image will always exceed the word—let’s accelerate the critique: Derungs’ work continues in a second space partially partitioned from this first room. Opposing three more “BW Negativs” which figure yet more quotidian aspects of the world is Minder’s gold spray paint and cuttlefish secretion mix: things that just shouldn’t work together do in the dialogue between stuff that Derungs and Minder have constructed. Minder makes things; Derungs makes images; together they make objects which inhabit their own world which we can approach and sensually engage with and come to grips with only on those objects’ own terms. This is best summarised by a final work made by Oliver Minder which on a third wall faces these two semi-partitioned spaces. A deep black stain about 100 X 200 cm with streak marks running down a further 2 metres hovers positioned to observe the whole work, and also to be part of this installation, too. This liminal flat suzerain lies in/out of the whole work. The stain of cuttlefish secretion resonates with Derungs’ sponge strokes on the church image; it mirrors the iris of an all-seeing eye; it combines material in situ with the situation itself. Where Minder’s other works have material and medium or substrate upon which the material is exercised, this single black hole is image which sucks everything up into itself. It draws the viewer, who must otherwise look away attentively at the floor work, and imagine horror, or smile at the ironic play of glitter. Look away at the image constructions that suggest how it is we too look to our world. See the play of thing and image in a third area. Or, finally return to the base of the pyramid that triangulates, to realise the stuff-image that unlocks it all for us. Black on white, organic on inorganic, material to substrate, that which in the falling out of one on the other, in its running down the wall simply gives form to both content and expression in one direction, and content and expression to form in another. NOTES In fact, glitter is used as associative forensic evidence: the 20,000 or so varieties are all uniquely identifiable.

It was Talbot’s surprising discovery that where a weaker chemical solution was more thinly spread, greater light sensitivity was actualized, yet this virtual image had then to be chemically developed in a second step.

continent. 1.4 (2011): 242—252. Introduction The following two works were produced by visual artist Jonas Staal and writer Vincent W.J. van Gerven Oei during a visit as artists in residence at The Bag Factory, Johannesburg, South Africa during the summer of 2010. Both works were produced in situ and comprised in both cases a public intervention conceived by Staal and a textual work conceived by Van Gerven Oei. It was their aim, in both cases, to produce complementary works that could (...) be read “through each other,” in which the movement of artistic construction would be imitated by textual deconstruction and vice versa. Both works deal with the way in which capital, apartheid, and monumentality are interwoven in South-African society. The Missing Link addresses a monument for democracy, erected on the premises of a private corporation running both an amusement park and the Apartheid Museum franchise. The textual intervention accompanying this public intervention investigates the limits of the inclusiveness of the anti-discrimination section in the South-African constitution, itself a monumental work of democracy. The Monument for the Distribution of Wealth deals with the history and eventual dissolution of a monumental square, commemorating the Soweto Uprising, in one of the poorest townships of Johannesburg. The history accompanying this public dismemberment of memory is equally fragmented, which is expressed by the many voices recounting uncertain and perhaps even irrelevant “facts” about the genius loci, the way in which the memorial space has actually entered into the memory of the inhabitants surrounding it. Next to their individual practices, Staal and Van Gerven Oei have worked together on a number of projects ever since 2007, including several art residencies. Their work involves an investigation of the different interfaces between art, politics, and public space in media ranging from theater and public interventions, to video installations and (co-authored) textual works. The Missing Link Missing Link (1) Missing Link (2) Missing Link (3) Intervention on the monument entitled The Seven Pillars of the Constitution , part of the Apartheid Museum in Johannesburg, South Africa. The Seven Pillars represent the constitutional values propagated in South Africa since the abolition of the apartheid regime. The monument and museum were built by the Gold Reef Resorts corporation, which is also responsible for the theme park and casino next to it. By placing the word “capitalism” on the wall surrounding the museum, the capitalist system and the constant social divisions that it implies are interpreted as sophistic continuations of apartheid politics. Through the capitalist system, apartheid is still operational within South African society. Whereas during the apartheid regime, the separation clearly ran along race divisions, in the current, “democratic” system, the same actual separation is sustained without it being an explicit element of the foundations of the country, i.e. the constitution. This intervention foregrounds the constant role of capitalism is both periods. At the same time the intervention acknowledges that contemporary Western artisthood is a mirror of the privileges that are offered by the capitalist system, and the type of artist that it produces. The intervention initiates a critical discourse concerning the capitalist system situated within the disaster of capitalism itself, in other words: through the desire to break with the presumption that art would be able to operate outside the capitalist system and to confirm that art—and the artist himself—is in fact modeled on this system. The public intervention by Staal was supplemented by a textual intervention by Van Gerven Oei: a proposition to alter the seventeenth amendment of the South African constitution. Even though the anti-discrimination legislation in South-Africa is one of the most stringent and inclusive in the world, one factor—wealth—remains outside its scope, thus continuing the schisms along racial lines produced during the apartheid regime: §9.3. The state may not unfairly discriminate directly or indirectly against anyone on one or more grounds, including race, gender, sex, pregnancy, marital status, ethnic or social origin, colour, sexual orientation, age, disability, religion, conscience, belief, culture, language, birth, and wealth. Monument for the Distribution of Wealth Intervention concerning the June 16 Memorial Acre in Central Western Jabavu, one of the poorest townships of Johannesburg. The monument comprises a park on which different are placed recalling an important protest the black population against the former apartheid regime. In 1976, from a school adjacent to the park, they started a massive protest against the introduction of Afrikaans in the school curriculum. The police reacted violently, and shot several hundreds of students. The construction of the June 16 Memorial Acre was started in 2005, and from the start was the paragon of corruption. Coordinated by local politicians, some family members of the protest leader from 1976 gained control of the realization of the monument, outside the regulation through external institutions. The available budget of 41 million rand (at that time well over 5 million euro) was largely embezzled. In the meantime, the monument has become fully dilapidated and defaced. The park has become overgrown with weeds and covered in a layer of dirt, and the local population is slowly plundering the square to use the material for the construction and decoration of their own houses. The Monument for the Distribution of Wealth develops the dynamics already existent around the June 16 Memorial Acre. Without obtaining official permission in advance, several local inhabitants were hired to break down the monument, sort the materials, and offer it to the neighborhood. Thus, the redistribution of wealth after the fall of the apartheid regime is finally taking place, albeit from the mere remains of the capital that was once invested in the community. The words “monument” and “for free” are spray-painted on the stacks of material, both in English and Zulu, as these are locally the most common languages. Van Gerven Oei supplemented Staal’s public intervention with an account of the history of the monument based on a series of interviews. The account clarifies how the different interests within the protest 1976 are reflected in the exceeding decay of the park, and how in the end those interests were represented by the June 16 Memorial Acre. Monument for the Distribution of Wealth 1: Removing stones Monument for the Distribution of Wealth 3: Pulling down statues Monument for the Distribution of Wealth 4: Offering the material Monument for the Distribution of Wealth 5: Offering the material Monument for the Distribution of Wealth 6 The next day A Fragmentary History of the Monument for the Distribution of Wealth, Formerly Known as the June 16 Memorial Acre in Central Western Jabavu, Soweto Vincent W.J. van Gerven Oei The following text, based on interviews and online research aims to provide parts of a history of the park in front of Morris Isaacson High School in Central Western Jabavu, Soweto. The idea for the transformation of the park into a memorial site has its source in the events of June 16, 1976: the start of the the student uprising in Soweto. The development of the park was started in the early 1980s, and the actual transformation into a memorial site, the June 16 Memorial Acre, was initiated in 2005. Over the last few years, several monumental additions have been made to the park: A marble monument with three pillars was revealed on June 16, 2006. A sculpture of a book and several billboards on June 16, 2008. A sculpture of student leader Tsietsi Mashinini on June 16, 2010. The park was transformed into the Monument for the Distribution of Wealth on August 3, 2010. According to the entry “Youth Struggle” on the website South African History Online, the Bantu Education Act was introduced in 1953 . In 1954 , Dr Verwoerd, Minister of Native Affairs, stated: “What is the use of teaching the Bantu child mathematics when it cannot use it in practice? That is quite absurd.” According to the entry “Soweto uprising” on Wikipedia, the Afrikaans Medium Decree was issued in 1974 , forcing all black schools to use Afrikaans and English in a 50-50 mix as languages of instruction. The Regional Director of Bantu Education (Northern Transvaal Region), J.G. Erasmus, told Circuit Inspectors and Principals of Schools that from January 1, 1975 , Afrikaans had to be used for mathematics, arithmetic, and social studies from standard five (7th grade). English would be the medium for general science and practical subjects. Indigenous languages would be used for religion instruction, music, and physical culture. According the entry “Soweto uprising” on Wikipedia, on April 30, 1976 , students from the Orlando West Junior School in Soweto went on strike, refusing to go to school. Their example was followed by other schools in Soweto. A student from Morris Isaacson High School, Toboho “Tsietsi” Mashinini, proposed a meeting on June 13, 1976 to discuss further action. According to Weizmann Hamilton’s article “The Soweto Uprising 1976,” which appeared in the September 1986 edition of Inqaba Ya Basebenzi (Fortress of the Revolution), on June 13, 1976 , the South African Students’ Movement called a meeting at the Donaldson Community Center in Orlando. 300-400 Students representing 55 schools decided to hold a mass demonstration on June 16. According to Brian Mokhele, member of the Joint Community Safety Forum, Dr Edelstein was the first victim of the Soweto uprising and killed the day before the march on June 15, 1976 . Edelstein was an administrator at the pass office in Jabavu and gave golf courses to the local community. Edelstein was put in a garbage bin and pierced by pickaxes. The garbage bin was left at the very spot of the murder for many years. A few years ago, a child was beheaded at the same spot, and the basketball court next to it has been abandoned since. According to Marcus Neustetter, founder of the Trinity Session, this story is untrue. According the entry “Soweto uprising” on Wikipedia, on June 16 , Tsietsi Mashinini led students from Morris Isaacson High School to join up with others who walked from Naledi High School. A crowd of between 3,000 and 10,000 eventually ended up near Orlando High School. According to Raymond Marlowe, a local photographer, Tsietsi Mashinini was heading the march. According to the entry “Hector Pieterson” on Wikipedia, Dr Edelstein died on June 16, 1976 , stoned to death by mob and left with a sign around his neck proclaiming “Beware Afrikaaners.” The first child to die that day was called Hastings Ndlovu. According to Pat Motsiri, Orlando West is claiming struggle heritage through the Hector Pieterson Museum, while Hector Pieterson was from Jabavu. According to Pat Motsiri, his generation effectively struggled between 1980 and 1991, forcing the release of Nelson Mandela and negotiations with the apartheid regime while the 1976-generation was safely in exile. Nevertheless, this has not been recognized in any monument. After the abolition of apartheid, the generation from 1976 returned from exile, occupied important government and ANC positions, creating an abundance of 1976 memorials and refusing to acknowledge that this was only possible because of the younger generation’s struggle. He calls this a generational conflict. According to Archibald Dlamini, the park officer responsible for the Memorial Acre, he started working for the municipality in 1978. In 1981/82 , Isaac Makhele from Pimville, who used to work in the cemetery business, was the first developer of the park. It used to be just a normal park until City Parks decided to develop the Memorial Acre in 2006. In 2007 the work was stopped by the community. According to Brian Mokhele, he left the country in 1989 after he participated in the riots of 1986. But when he returned in 1999 he found that nothing had changed. He says that they were promised to be protected by the Constitution, but that reality is different. The police uses fear to suppress them so that they don’t come out to talk openly. He has been arrested twice, both times harassed and tortured by the police, but in the end always released without indictment. He says that this is their way to threaten communities to back off from politics. According to Moses, who is sitting outside rolling a joint, Brian knows everything. He tells Brian to tell me everything he knows. According to Brian Mokhele, Tsietsi Mashinini was possibly murdered in 1990 during his exile in New York. Two weeks before he was supposed to return to South Africa, his papers in order, he was found dead under mysterious circumstances. His coffin was sealed when he was buried. According to Pat Motsiri, he came up with the idea for the Memorial Acre in 2003 . He submitted the documents for the proposal to the council, which sidelined him as soon as the budget came out in 2005 . According to Brian Mokhele, there was on estimation R 41,000,000 spent to redesign the park and turn it into the Memorial Acre. The millions were divided by Amos Masondo, the mayor of Soweto, the local councilor Bongani D. Zondi, and the director of the city of Johannesburg, Pat Lephunya. They were dividing the money between several contractors: Tsietsi Mashinini’s brothers were involved in the development of the park, they got the tender to do the green areas, the landscaping. Construction was done by other companies, some did the paving, the toilets, etc. EMBA, a private company appointed by the municipality was in control of the money flow, but the money was quickly gone. According to Raymond Marlowe, the contractor bought a BMW with the money. According to Archibald Dlamini, the Mashinini brothers got the tender, so the space would look more like the other places around in Soweto. It was agreed that after they were done, they would return the property to the municipality. They did whatever they could do. According to Mafaisa, a member of the Jabavu business community, he was one of the contractors for the landscaping and the pavement under Mpho Mashinini, one of the brothers. He says that I should contact Mavi for information on Mpho. According to Poi Stuurman, a local youth worker, Mafaisa is one of the guys who ran away with the money. According to Mavi, Mpho Mashinini was never a contractor. The contracts were organized by Sbu Butelezi, the former head of the Gauteng Department for Public Works. The June 16 Foundation and the Mashinini brothers will be the beneficiaries of the park when it is finished. According to Brian Mokhele, City Parks did not accept the Memorial Acre because it was not finished. The rest of the year, the unfinished park is not maintained, as should have happened. This was done deliberately so that in the end they can just clean the whole thing up and have a reason to redo the whole park. According to Brian Mokhele, the Mashinini brothers now work for the government. People that manipulate for money purposes always come from the government’s side. Because the park was left unfinished, the people from the neighborhood are taking away the stones to decorate their own homes with. According to Archibald Dlamini, because City Parks doesn’t accept responsibility of the park, he officially has nothing the guard, except for his cottage, which is municipal property. The thieves come at night and destroy the park, but he cannot do anything because he is sleeping. According to the website of the Thanda Foundation on June 16, 2006 a bronze statue of Hector Pieterson, the first child to die in the 1976 protests, made by Kobus Hattingh and Jacob Maponyane was unveiled in the Maponya Mall in Soweto. The statue is sculpted after the famous image shot by Sam Nzima of Mbuyisa Makhubo carrying the dead body of the boy. The sculpture was sponsored by the Thanda Foundation, founded by the Swedish entrepreneur Dan Olofsson and South-African entrepreneur Matthews Phosa. According to the official website of the City of Johannesburg, the Memorial Acre and Artwork were unveiled in 2006. According to a blog post on sowetouprisings.com, the Memorial Acre was still under development on July 24, 2006. According to Archibald Dlamini, City Parks only cleans up the park once a year just before the June 16 celebrations. Everybody is waiting for the Mashinini brothers to finish their job. The last time he talked with them was in 2007 . According to a sign on the school grounds of the Morris Isaacson High School, the June 16 Trail will be finished in 2008 . According to a blog post on sowetouprisings.com, the Memorial Acre contains another monument erected in Tsietsi’s honor. The monument was created as part of the Sunday Times Heritage Public Art program. Its physical form resembles a giant book which symbolizes the crisis in education experienced in 1976. On the face of the book is the map of the route taken by the students from Morris Isaacson High School in Central Western Jabavu to Phefeni Junior Secondary in Orlando West (currently the site of the Hector Pieterson Museum), while the back cover of the ‘book’ is inscribed with a tribute to Tsietsi Mashinini. The monument was revealed on June 16, 2008 . According to Marcus Neustetter, the billboards on the Memorial Acre were part of a school project realized in 2008. Following several workshops, the students from different high schools along the June 16 Trail were invited to work with artists on the billboards, while the neighborhood community was invited to watch the process during the festivities on June 15 and 16, 2008 . The billboards were supposed to be removed because of construction works on the Memorial Acre, which never ended up happening. According to Brian Mokhele, the former toilet facilities were converted into a house for the park officer. This park officer has been working for city parks for more than 12-15 years, but does nothing here, because the park, including the new toilet buildings, is not finished. The government is now moving around looking for people to take this job because they stopped it. They confronted everybody who was going in and chased them away. According to John, in 2009 , some girls, around 16 or 17 years old, were raped by four men who had been drinking in a local shebeen. When the bar quit they said that they would go home by car, but instead raped the girls on the Memorial Acre nearby. This happened in the unfinished toilets, because the doors couldn’t be closed. According to Brian Mokhele, there used to be some fences around the park because of the construction work that was eventually stopped, but these were also stolen. According to Archibald Dlamini, people from the neighborhood started about two and a half years ago, and the last piece was stolen near the end of 2009 . Sometimes he would catch someone with a roll of fence, and then use it for his own cottage. According to the official website of the City of Johannesburg, a statue of Tsietsi Mashinini by Johannes Pokhela was revealed on June 16, 2010 , “Youth Day.” According to Shirley Makutoane, deputy principal of Isaac Morrison High School, the statue of Tsietsi Mashinini, funded by the June 16 Foundation, has temporarily been placed within the school perimeter. The statue will be moved to the Memorial Acre when it will be finished, in 2011 . According to Brian Mokhele, beside the June 16 Foundation, there is also a June 16 Memorial Acre Foundation. Both foundations are quarreling about the money involved in the Memorial Acre project. Nobody knows who’s involved in them. According to Marcus Neustetter, the June 16 Foundation consists of people that were part of 1976 protest movement, local government officials, representatives of the Hector Pieterson Museum, and the council. According to students from the Isaac Morrison High School, the statue of Tsietsi Mashinini is on the school ground because on the Memorial Acre it would be vandalized by youths from White City, an adjacent neighborhood. Accorcing to Brian Mokhele, the statue of Tsietsi should eventually be mounted on the Memorial Acre. It is wrong that the statue is in the school at the moment, because it is not a public school. He wants the statues to depict the massiveness of the force that was coming into Soweto after the protests. According to Brian Mokhele, City Parks, City of Jo’burg, City Lights, and SAPS are making some sort of plan to take the plan back. They want to remove the trees from the Memorial Acre, and redesign the Memorial Acre into a relaxing park, without political content. They want to depoliticize the square. In doing so,they will have their own employment and not use local workforces. According to Brian Mokhele, the community wants to remove the monuments, amphitheater, and sculptures from the Memorial Acre because they do not resemble anything. The sculptures should be depicting the truth of what happened, because the Memorial Acre is a political heritage site. He wants to involve the people that actually participated in the struggle to make the monument so that everyone can enjoy it and get a better understanding of the struggle heritage. Therefore, he proposes collective ideology in which everyone has a say. This would prevent future vandalization of the monument. According to Pat Motsiri, the sculptures must depict the event around June 16, 1976. Like the story of Dr Edelstein, who was pierced by pickaxes, forced into a garbage bin and burned alive. According to Jonas Staal, the Memorial Acre should be destroyed, its elements stacked on pallets, thus forming the Monument for the Distribution of Wealth . According to Mafaisa, his men can do the work quickly. He has about twenty men working under him. (shrink)
