A conclusion is a “material consequence” of reasons if it follows necessarily from them in accordance with a valid form of argument with content. The corresponding universal generalization of the argument’s associated conditional must be true, must be a covering generalization, and must be true of counter-factual instances. But it need not be law-like. Pearl’s structural model semantics is easier to apply to such counter-factual instances than Lewis’s closest-worlds semantics, and gives intuitively correct results.

According to Alfred Tarski’s classical definition, logical consequence is necessary and formal. This paper focuses on the question: In what sense (if any) is material consequence a logical relation? For Tarski, material consequence has no modal force. Treating all terms (of a language with a fixed domain) as logical, he reduces logical consequence to material consequence. Thus, Tarskian material consequence seems to be a logical oxymoron designed to emphasize the importance (...) of the distinction between logical and extra-logical terms for the definition of logical consequence. Historically, however, there have been different approaches to material consequences. This paper attempts to provide an investigation into the parallels between Tarski’s dichotomy of formal and material consequence and the modern. (shrink)

Today's modern car is an assemblage of mechanical and digital components, of metal panels that comprise its structure and silicon chips that run its functions. Communication and information studies scholars have interrogated the problematic aspects of the programs that run those functions, revealing serious issues surrounding privacy and security, worker surveillance, and racial, gendered, and class-based bias. This article contributes to that work by taking a step back and asking about the issues inherent not in the software running on these (...) chips, but on the microchips themselves. Using the lens of “chipification”—the process by which a device is rendered capable of reading and processing data through the embedding of microchips—this article explores how the integration of microchips also involves processes that are often borne from, replicate, or create troubling power dynamics of their own. It takes light-duty passenger vehicles as a case study into how chipification is radically reshaping such processes as resource allocation, labor flows, and cultural practices around car manufacture, use, repair, and modification. By naming the process of chipification, this article allows researchers to identify and analyze the ways that integrating data processing capabilities into everyday devices is not a frictionless practice, but rather one that implicates a variety of power dynamics within these massive industries.

_ Source: _Volume 56, Issue 3-4, pp 241 - 271 William of Ockham and John Buridan provide different accounts of the distinction between formal and material consequences. Some consequences – in particular, enthymemes – that Ockham would classify as formal would be classified as material by Buridan. This paper explains this taxonomical discrepancy. It identifies the root of the discrepancy not in a difference between Ockham’s and Buridan’s notions of propositional hylomorphism but rather in Ockham’s endorsement of relational (...) characterizations of consequences.

Everyday reasoning is replete with arguments which, though not logically valid, nonetheless harbor a measure of credibility in their own right. Here the claim that such arguments force us to acknowledge material validity, in addition to logical validity, is advanced, and criteria that attempt to unpack this concept are examined in detail. Of special concern is the effort to model these criteria on explications of logical validity that rely on notions of substitutivity and logical form. It is argued, however, (...) that such a parallel is not easily located and that it is uncertain that a construal of material validity can be fashioned after traditional accounts of logical validity. Attention is also given to the topics of enthymemes and to the proper domain of logic. (shrink)

The recovery of Aristotle’s logic during the twelfth century was a great stimulus to medieval thinkers. Among their own theories developed to explain Aristotle’s theories of valid and invalid reasoning was a theory of consequence, of what arguments were valid, and why. By the fourteenth century, two main lines of thought had developed, one at Oxford, the other at Paris. Both schools distinguished formal from material consequence, but in very different ways. In Buridan and his followers in (...) Paris, formal consequence was that preserved under uniform substitution. In Oxford, in contrast, formal consequence included analytic consequences such as ‘If it’s a man, then it’s an animal’. Aristotle’s notion of syllogistic consequence was subsumed under the treatment of formal consequence. Buridan developed a general theory embracing the assertoric syllogism, the modal syllogism and syllogisms with oblique terms. The result was a thoroughly systematic and extensive treatment of logical theory and logical consequence which repays investigation. (shrink)

_ Source: _Volume 56, Issue 3-4, pp 292 - 319 With William of Ockham and John Buridan, Walter Burley is often listed as one of the most significant logicians of the medieval period. Nevertheless, Burley’s contributions to medieval logic have received notably less attention than those of either Ockham or Buridan. To help rectify this situation, the author here provides a comprehensive examination of Burley’s account of consequences, first recounting Burley’s enumeration, organization, and division of consequences, with particular attention to (...) the shift from natural and accidental to formal and material consequence, and then locating Burley’s contribution to the theory of consequences in the context of fourteenth-century work on the subject, detailing its relation to the earliest treatises on consequences, then to Ockham and Buridan.

In this paper I examine Avicenna’s conception of the consequence relation. I will consider in particular his categorical and hypothetical logics. I will first analyse his definition of the implication and will show that this relation is not a consequence relation in his frame. Unlike the medieval logicians, he does not distinguish explicitly between material and formal consequences. The arguments discussed in al-Qiyās, where the conclusion is true only in some matters, and would seem close to a (...) material consequence for that reason, are rejected explicitly as not syllogistic. He also rejects the ‘enthymemes’ unless they are complemented by their missing premise and the superfluous premises which, according to him, should promptly be ruled out. It seems then that the consequence relation in his theory is formal. It can be characterized as being ‘productivity in all matters’ or ‘necessary truth preserving’. It is illustrated by some single premise arguments, and above all by all kinds of syllogisms which, in his theory, are more numerous and various than in Aristotle’s one. The syllogism may contain two or more premises, including disjunctive ones. When it is hypothetical, it may lead to several conclusions. The premises may be in conflict, but then, the conclusion is false. He thus rejects the principle according to which ‘anything follows from a contradiction’. But, unlike what some scholars say, he does not admit any connexive principle. In the compound syllogisms, the conclusion follows by steps, each step taking two premises at once. (shrink)

Tarski's 1936 paper, “On the concept of logical consequence”, is a rather philosophical, non-technical paper that leaves room for conflicting interpretations. My purpose is to review some important issues that explicitly or implicitly constitute its themes. My discussion contains four sections: terminological and conceptual preliminaries, Tarski's definition of the concept of logical consequence, Tarski's discussion of omega-incomplete theories, and concluding remarks concerning the kind of conception that Tarski's definition was intended to explicate. The third section involves subsidiary issues, (...) such as Tarski's discussion concerning the distinction between material and formal consequence and the important question ofthe criterion for distinguishing between logical and non-logical terms.§1. Preliminaries. In this paper an argument is a two-part system composed of a set of propositions P and a single proposition c. The expression ‘c is a [logical] consequence of P’ is used with the same meaning as the expression ‘c is [logically] implied by P’. The expressions ‘is a logical consequence of’ and the converse ‘implies’ are relational. Often, I shall be talking in the same sense of validity of an argument. Validity is a property of arguments; an argument with premise-set P and conclusion c is valid if and only if P implies c; i.e., c is a logical consequence of P. Notice that this notion of argument is strictly ontic; it does not involve any agent that thinks, determines or establishes that a given proposition is or is not a consequence of a given set of propositions.

This paper seeks to address the relation of materiality to structure and phenomena of signification or semiosis. It examines the logical consequences of several major lines of argument concerning the status of semiosis with regards to the human or broadly “organic” life-world and to the “zero degree” of base materiality — from Peirce to Lotman and Sebeok — and questions the classificatory rationale that delimits semiosis to the exclusion of a general treatment of dynamic systems. Recent investigations into neurosemiotics have (...) provided salient arguments for the need to treat semiosis as a characteristic of systems in general, and to establish a more transverse understanding of signifiability upon the basis of what makes dynamic structures, as such, possible.

The presented papers are very interesting. They differ and complement one another… . Orlova's presentation is a model of structuralization, scientific rigor, extreme precision, and clarity. Shemanov's paper provides a philosophical basis for culturology. I asked what place culturology occupies in the field of knowledge. It turned out that to answer this question it is first necessary to present the system of manifestations of a society's life activity and only then, when we have the matrix, can we compare our idea (...) of culture with it in order to make it relevant to that matrix. This is to correlate the patrix and the matrix. But since there are no generally accepted schemata of society, no developed schemata of its cognitive activity, I had to work on my own. I offer two schemata but, in view of the time limit, I will only indicate certain items of this context so as to make it clear what I am talking about and from what premises I proceed. There are several premises. The first is the main problem that must be borne in mind in any theorizing. How is our material existence correlated with the realization of our creative potential, our subjectivity? This is the problem of man's spiritual development. It would appear to be a truism. But it is necessary to find a philosophical expression for this problem. This means to find a formula, because if a study is not summed up in a formula it has to be continued. The philosophical equivalent of the problem of existence is: existence determines consciousness, consciousness reflects existence. This is a contribution of Marxism. It would seem that those who theorized about the active nature of consciousness, thought, and the subjective factor have all the advantages, since that was all they worked on and spoke of the primacy of consciousness. Why, then, have they not discovered the formula of the correlation between material existence and creative subjectivity? Because then there is a clash of two paradigms, and formal logic comes into force, stating that it is necessary to make a choice, for there is no third way. We want to construct a philosophical equivalent of the activity of consciousness and say what role it plays. As long as we simply say that it plays a huge or important role, or that consciousness has a reverse effect, our research has not been completed. If existence determines consciousness, then thought, in turn, makes reality similar to itself. Consequently, I distinguish existence and reality. But whence this distinction? If we go back to the definition that matter is a philosophical category for denoting objective reality, then it becomes clear that objective reality is that which exists outside and independently of us. If we have different words-outside of us and independently of us-then this is a substantial difference. Even so perspicacious an analyst as Freud separated these concepts with a comma. So I tried to separate them vertically and horizontally. Vertically, we have that which is in reality and, horizontally, that which exists independently of us. We obtain a definite square. Existence-consciousness-activity-reality. Everything else is purely technical. Here is the genesis of the matrix. This leads to many consequences. Superimposing this schema on the matrix, I obtained a fairly clear picture. They turn out to be relevant to each another. We get varieties of knowledge such as intuitive or, if we think in binary oppositions, the instinctive is opposed to the distantive variety, and first of all science, because it knows not directly, but through mediation. Instinctive knowledge is instantaneous, one-time knowledge. Here the logic of common sense and other things operates. And then, when we correlate activity and reality, we have the objective and subjective varieties. Corresponding to these varieties, as a result of cognition we acquire knowledge: intuitive-direct, distantive-mediated, subjective-procedural, and objective-object-oriented. If we take such characteristics as the bases of cognitive varieties, the means of knowledge, the forms of knowledge, cognitive approaches, and objects of knowledge, we get a special table. Mendeleev had a table of chemical elements; I have a table of social elements consisting of twenty-eight squares. In a division into so many categories, if there is a logical mistake, there must be a flaw somewhere. I do not detect any flaws here, and this indicates that such a division is not fortuitous: the table reflects a law. There are also other premises such as "we are in the world, and the world is in us." We are in the world physically, while the world is in us mentally. We live surrounded by nature, but also at the price of nature. My schemata are based on these presuppositions. Consequently, one cannot counterpose the achievements of philosophical materialism and idealism. At this stage they must be not opposed, but synthesized, united. This is to dismiss the claim of every doctrine that it is absolute. If we see the relatively rational in each doctrine and join them together, we shall get a contemporary synthetic philosophy that works. I was able to show how this methodology works, in this case, with this example. In analyzing such an urgent social phenomenon as conflict, I found that conflict situations can be broken down into elements. Now I know how to order the sides in a conflictual situation, how they are correlated. And when there is a link with a schema of categories, then things work well. (shrink)

ABSTRACT According to the material-heuristics hypothesis, people’s socioeconomic position affects their perceptions about the socioeconomic environment, including how society distributes opportunities and rewards and to what extent people are responsible for their own economic situation. These perceptions, in turn, affect attitudes toward wealth redistribution. In contrast to the material-heuristics hypothesis are the more familiar material self-interest hypothesis, which relates redistributive attitudes to one’s personal interest in gaining or losing from redistribution; and the self-serving reasoning hypothesis, according to (...) which perceptions of how society distributes opportunities and rewards are a consequence rather than a cause of attitudes toward redistribution, which are, in turn, driven by material self-interest. All three hypotheses connect socioeconomic position and attitudes toward redistribution, but only the material-heuristics and the self-serving reasoning arguments account for why perceptions of the causes of wealth and poverty vary across economic groups and why this variation matters for attitudes toward redistribution. Ignoring the role of such perceptions can lead to the simplistic attribution of attitudes toward redistribution to personal self-interest. (shrink)

The process of self-awareness and awareness of the surrounding world for Muslim scholars has been categorized into divisions such as experiential and acquired awareness. However, the ontology of awareness, meaning the discussion of whether awareness is immaterial or material, as well as the material or immaterial nature of the origin and end of awareness, has been a particularly challenging topic among Muslim theologians. Some Muslim scholars, denying the existence of a factor beyond the human body for his movement (...) and life, considered both awareness and the process of awareness formation in humans and the factor shaping awareness in humans to be within the same body. They engaged in critiquing the perspectives and foundations of philosophers, especially Ibn Sina, on this matter and, utilizing specific principles in their philosophical physicalistic psychology, regarded awareness as a material entity. In this discussion, after examining the foundations of this group of Muslim theologians regarding the material nature of awareness and their criticisms of considering awareness as immaterial, we will focus on the philosophical and epistemological consequences arising from their materialistic view of awareness in their thought.

In a rich and thought-provoking paper, Lambros Malafouris argues that taking material culture seriously means to be ‘systematically concerned with figuring out the causal efficacy of materiality in the enactment and constitution of a cognitive system or operation’ (Malafouris 2004, 55). As I understand this view, there are really two intertwined claims to be established. The first is that the things beyond the skin that make up material culture (in other words, the physical objects and artefacts in which (...) cultural networks and systems of human social relations are realized) may be essential to the enactment of, and be partly constitutive of, certain cognitive systems or operations. The consequence of establishing this claim is supposed to be that we have a mandate to recast the boundaries of the mind so as to include, as proper parts of the mind, things located beyond the skin. Thus, in talking about the contribution of the world to cognition, Malafouris (2004, 58) concludes that ‘what we have traditionally construed as an active or passive but always clearly separated external stimulus for setting a cognitive mechanism into motion, may be after all a continuous part of the machinery itself; at least ex hypothesi’. This is the position that, in philosophical circles, is known increasingly as the extended mind hypothesis (Clark & Chalmers 1998; Menary forthcoming). Henceforth I shall refer to this hypothesis as EM. A stock example will help bring the idea into view. Rumelhart et al. (1986) note that most of us solve difficult multiplication problems by using ‘pen and paper’ as an external resource. This environmental prop enables us to transform a difficult cognitive problem into a set of simpler ones, and to temporarily store the results of certain intermediate calculations. For the fan of EM, the distributed combination of this external resource and certain inner psychological processes constitutes a cognitive system in its own right. (shrink)

In contrast to the history of science and to science and technology studies, the value discourse in the philosophy of science has not provided a thorough analysis of the material culture of science. Instruments in science have a special characteristic, namely that they explicitly and clearly emerge from and remain embedded in social contexts, and are thus imbued with values. We argue that the materials (in most cases they are artifacts) used in science are necessarily influenced by both epistemic (...) and non-epistemic considerations. A consequence of this is that a descriptive term cannot give sufficient information whether an artifact is performing in an acceptable way. Instead of the prevailing descriptive approach, we therefore advocate a normative notion of values in the material culture of science. To this end, we connect the material culture of science to the so-called “new demarcation problem”, in order to lay the foundations for a value-sensitive approach to the analysis of instruments. By assessing the five approaches of demarcation concerning value-influences, it will be shown that they break down at various points if the material aspects of science are taken seriously. (shrink)

This paper critically examines I.I. Rubin's Essays on Marx's Theory of Value and argues that two different approaches to value theory can be found in that book: a more 'production-centred' value-form theory uneasily co-exists with a 'circulationist' perspective. This unresolved tension, the authors claim, reflects a more general theoretical shortcoming in Rubin's work, namely, a problematic conceptualisation of the inner connection between materiality and social form that eventually leads to a formalist perspective on the value-form. Furthermore, the paper argues that (...) all those antinomies are an expression of the historical and political context underlying Rubin's work, in which Marxism was being codified as state ideology. The political implications of Rubin's formalism are explored through the critical examination of its consequences for the comprehension of the social determinations of the revolutionary subjectivity of the working class.

A number of papers have argued in favour of the material account of indicative conditionals, but typically they either concentrate on defending the account from the charge that it has counterintuitive consequences, or else focus on some particular positive argument in favour of the theory. In this paper, I survey the various positive arguments that can be given, presenting simple versions where possible and showing the connections between them. I conclude with some methodological considerations.

During the course of the COVID-19 pandemic, a wide range of digital technologies and data analytics have been incorporated into pandemic response models globally, in the hope of better detecting, tracking, monitoring and containing outbreaks. This increased digital involvement in disease control has offered the prospect of heightened effectiveness in all of the above, but not without raising other concerns. This paper contributes to ongoing discussions of the digital transformation in disease control by proposing a materialist analysis of how such (...) control has become operative and what its effects may be, both now and in the future. Using Taiwan's digital pandemic response as a case study, the paper explores specific ways in which material processes and arrangements have shaped digital measures, as well as the actions that rendered such measures operable, with their ensuing consequences. This analysis illustrates the importance of historical, material and technological specificities and contingencies to our understanding of how digital disease control takes a particular shape. It also demonstrates how shifting regimes of practice continually reconfigure the ways in which digital disease control functions. The paper argues that paying greater attention to the materialities of digital disease control can provide a more nuanced understanding of the complex ways in which society may be protected or harmed by its use, possibly simultaneously. It is hoped that such increased attentiveness may inform more considered and careful preparation for subsequent pandemics. (shrink)

Timothy Williamson argues against the tactic of criticizing confidence in a theory by identifying a logical consequence of the theory whose probability is not raised by the evidence. He dubs it “the consequence fallacy”. In this paper, we will show that Williamson’s formulation of the tactic in question is ambiguous. On one reading of Williamson’s formulation, the tactic is indeed a fallacy, but it is not a commonly used tactic; on another reading, it is a commonly used tactic (...) (or at least more often used than the former tactic), but it is not a fallacy. (shrink)

What is the relationship between mental states and items of material culture, like notebooks, maps or lists? The extended mind thesis offers an influential and controversial answer to this question. According to ExM, items of material culture can form part of the material basis for our mental states. Although ExM offers a radical view of the location of mental states, it fits comfortably with a traditional, representationalist account of the nature of those states. I argue that proponents (...) of ExM would do better to adopt a fictionalist approach to mental states. In so doing, I suggest, they could retain the important insights underlying the extended mind thesis, while avoiding its more problematic consequences. (shrink)

Cogency is the central normative concept of informal logic. But it is a loose evaluative concept and I argue that a generic notion covering all of the qualities of a well-reasoned argument is the most plausible conception. It is best captured by the standard RSA criterion: in a good argument acceptable (A) and relevant (R) premises provide sufficient (S) grounds for the conclusion. Logical qualities in a broad sense are affected by the epistemic qualities of the premises and “consequence” (...) in a broad sense exhibits an interplay of form and content. There are four proposals for the premise—conclusion relation: (i) no strictly logical connection (“non-logical” consequence); (ii) one type of connection only (deductivism); (iii) a few types of connection (deduction, induction, perhaps conduction and analogical reasoning); (iv) many types of connection (argumentation schemes). Deductivism is a serious option but in its strong version, as the discussion about petitio shows, it fails to establish that arguments which are not cogent are thereby invalid. And weak deductivism, very attractive from the pedagogical point of view, has some deficiencies (implausible hidden premises; preservation of truth, not probability). I argue that the idea of a counterexample, when we regard certain components of the argument as fixed and others as variable, is the best approach to the analysis of the illative core of every-day arguments (the approach of David Hitchcock on material consequence).

Abstract There is one assumption that is shared by practically all popular religious and philosophic systems, ancient and modern, Eastern and Western. In truth it may well be that it is this single assumption which makes such ?systems? possible. That shared assumption is the belief in a ?just universe?, i.e. ?just? in the sense of morally ordered, morally predictable and morally explainable. This assumption rests, as most assumptions must, on pragmatic grounds; that is to say, the assumption is retained or (...) used because it gets the users where they want to go, i.e. the assumption works. But if it could be shown that this assumption, aside from being useful, leads to insuperable logical or empirical problems, then this might be prima facie grounds for rejecting the assumption. Part I examines the historical roots of the assumption of a just universe. Part II, examines three implications that would seem to follow from the assumption that the universe, the world, is a just place in which to live. Part III explores the unacceptable consequences that are found in and that follow from these three implications and that necessitate the rejection of the assumption of the just universe of Part I.

In _Aesthetics and Material Beauty_, Jennifer A. McMahon develops a new aesthetic theory she terms Critical Aesthetic Realism - taking Kantian aesthetics as a starting point and drawing upon contemporary theories of mind from philosophy, psychology, and cognitive science. The creative process does not proceed by a set of rules. Yet the fact that its objects can be understood or appreciated by others suggests that the creative process is constrained by principles to which others have access. According to her (...) update of Kantian aesthetics, beauty is grounded in indeterminate yet systematic principles of perception and cognition. However, Kant’s aesthetic theory rested on a notion of indeterminacy whose consequences for understanding the nature of art were implausible. McMahon conceptualizes "indeterminacy" in terms of contemporary philosophical, psychological, and computational theories of mind. In doing so, she develops an aesthetic theory that reconciles the apparent dichotomies which stem from the tension between the determinacy of communication and the indeterminacy of creativity. Dichotomies such as universality and subjectivity, objectivity and autonomy, cognitivism and non-cognitivism, and truth and beauty are revealed as complementary features of an aesthetic judgment.

Making Worlds brings together thirty-one distinguished feminist activists, artists, and scholars to address a series of questions that resonate with increasing urgency in our current global environment: How is space imagined, represented, arranged, and distributed? What are the lived consequences of these configurations? And how are these questions affected by gender and other socially constructed categories of "difference"—race, ethnicity, sexuality, class, nationality? How are the symbolic formations of place and space marked by cultural ideologies that carry across into the places (...) and spaces we inhabit, the boundaries and institutions we maintain? In recent years these questions have occasioned intensifying debates, but they have seldom extended beyond the boundaries of individual academic disciplines or crossed the divide that has traditionally separated the academy from the "outside" world. Making Worlds both questions and traverses those divisions by combining personal essays, activist political rhetoric, oral history, poetry, iconography, and performance art with interdisciplinary academic discourses. Representing a wide range of perspectives, Making Worlds develops a provocative conversation about gender and spatiality in the interwoven symbolic and material environments we create. The contributors engage such issues as the body as site of symbolic action, fabrication, and desire; the place and play of sexualities; the cultural implications of everyday life—home, travel, work, childbirth, food, disease, and death; technology and mass media; surveillance, confinement, and the law; the dynamics of race and ethnicity; imperialism, oppression, and resistance; the politics of urban spaces; landscape and cultural memory; the experience of time; and the nature of "Nature." For students and scholars in cultural studies, geography, literary criticism, anthropology, history, and women's studies, it offers new ways of thinking about space, place, and the spatial contexts of social thought and action.

In the influential 1995 article “Social Conditions as Fundamental Causes of Disease,” Bruce Link and Jo Phelan described social and political factors as “fundamental causes” of death and disease. Whitney Pirtle has recently declared racial capitalism another such fundamental cause. Using the case of the water crisis in Flint, Michigan, she has argued that racial capitalism's role in that situation meets each of the criteria Link and Phelan's article outlines: racial capitalism influenced multiple disease outcomes, affected disease outcomes through multiple (...) risk factors, involved access to flexible resources that can be used to minimize both risks and the consequences of disease, and was reproduced over time through the continual replacement of intervening mechanisms. We argue for Pirtle's conclusion using the extensive literature on racial capitalism and case studies concerning housing in the United States and Brazil and what Naomi Klein has termed “corona capitalism” in India. If races correspond to hierarchies of material security, as suggested by Ruth Wilson Gilmore, then these hierarchies and their causal effects are fundamental determinants of public health. (shrink)

This article sheds new light on Bruno Latour’s sociology of science and technology by looking at his early study of the French writer, philosopher and editor Charles Péguy (1873–1914). In the early 1970s, Latour engaged in a comparative study of Péguy’s Clio and the four gospels of the New Testament. His 1973 contribution to a Péguy colloquium (published in 1977) offers rich insights into his interest in questions of time, history, tradition and translation. Inspired by Gilles Deleuze’s philosophy of difference, (...) Latour reads Clio as spelling out and illustrating the following argument: ‘Repetition is a machine to produce differences with identity’. However, in contrast to Deleuze’s work (together with Félix Guattari) on the materiality of machines, or assemblages [agencements], Latour emphasizes the semiotic aspects of the repetition/difference process. As in Péguy, the main model for this process is the Roman Catholic tradition of religious events. The article argues that it is this reading of Péguy and Latour’s early interest in biblical exegesis that inspired much of Latour’s later work. In Laboratory Life (Latour and Woolgar, 1979) and The Pasteurization of France (1988) in particular, problems of exegesis and tradition provide important stimuli for the analysis of scientific texts. In this context, Latour gradually transforms the question of tradition into the problem of reference. In a first step, he shifts the event that is transmitted and translated from the temporal dimension (i.e. the past) to the spatial (i.e. from one part of the laboratory to another). It is only in a second step that Latour resituates scientific events in time. As facts they are ‘constructed’ but nevertheless ‘irreducible’. They result, according to Latour, from the tradition of the future. As a consequence, the Latourian approach to science distances itself from the materialism of Deleuze and other innovative theoreticians. (shrink)

This Element is a survey of central topics in the metaphysics of material objects. The topics are grouped into four problem spaces. The first concerns how an object's parts are related to the object's existence and to the object's nature, or essence. The second concerns how an object persists through time, how an object is located in spacetime, and how an object changes. The third concerns paradoxes about objects, including paradoxes of coincidence, paradoxes of fission, and the problem of (...) the many. The fourth concerns views with radical consequences regarding the existence of composite material objects, including mereological nihilism, ontological anti-realism, and deflationism. (shrink)

ABSTRACT The concept of paraconsistent logical consequence is usually negatively defined as a validity semantics in which not every sentences is deducible or in which inferential explosion does not occur. Paraconsistency has been negatively characterized in this way because paraconsistent logics have been designed specifically to avoid the trivialization of deductive inference entailed by the classical paradoxes of material implication for applications in a system that tolerates syntactical contradictions. The effect of the negative characterization of paraconsistency has been (...) to encourage an unsystematic development of distinct versions of paraconsistent logic. It has also contributed to a restricted overview of the full range of paraconsistent formalisms. After reviewing a standard negative characterization of paraconsistency and commenting on its limitations, I propose a positive characterization that makes possible a constructivistic description of the complete spectrum of distinct families of paraconsistent logics, and the description of a new type of maximally relevant paraconsistency, which I argue compares favorably with previously identified categories of paraconsistent logics.

Many have interpreted symbolic material culture in the deep past as evidencing the origins sophisticated, modern cognition. Scholars from across the behavioural and cognitive sciences, including linguists, psychologists, philosophers, neuroscientists, primatologists, archaeologists, and palaeoanthropologists have used such artefacts to assess the capacities of extinct human species, and to set benchmarks, milestones, or otherwise chart the course of human cognitive evolution. To better calibrate our expectations, the present paper instead explores the material culture of three contemporary African forager groups. (...) Results show that, although these groups are unequivocally behaviourally modern, they would leave scant long-lasting evidence of symbolic behaviour. Artefact sets are typically small, perhaps as a consequence of residential mobility. When traded materials are excluded, few artefacts have components with moderate–to–strong taphonomic signatures. The present analyses show that artefact function influences preservation probability, such that utilitarian tools for the processing of materials and the preparation of food are disproportionately likely to contain archaeologically traceable components. There are substantial differences in material use among populations, which create important population-level variation in preservation probability, independent of cognitive differences. I discuss the factors – cultural, ecological, and practical – that influence material choice. In so doing, I highlight the difficulties of using past material culture as an evolutionary or cognitive yardstick. (shrink)

There is a well-known argument from Leibniz's Law for the view that coincident material things may be distinct. For given that they differ in their properties, then how can they be the same? However, many philosophers have suggested that this apparent difference in properties is the product of a linguistic illusion; there is just one thing out there, but different sorts or guises under which it may be described. I attempt to show that this ‘opacity’ defence has intolerable consequences (...) for the functioning of our language and that the original argument should therefore be allowed to stand. (shrink)

Thus, in talking about the contribution of the world to cognition, Malafouris (2004, 58) concludes that ‘what we have traditionally construed as an active or passive but always clearly separated external stimulus for setting a cognitive mechanism into motion, may be after all a continuous part of the machinery itself; at least ex hypothesi’. This is the position that, in philosophical circles, is known increasingly as the extended mind hypothesis (Clark & Chalmers 1998; Menary forthcoming). Henceforth I shall refer to this hypothesis as EM. A stock example will help bring the idea into view. Rumelhart et al. (1986) note that most of us solve difficult multiplication problems by using ‘pen and paper’ as an external resource. This environmental prop enables us to transform a difficult cognitive problem into a set of simpler ones, and to temporarily store the results of certain intermediate calculations. For the fan of EM, the distributed combination of this external resource and certain inner psychological processes constitutes a cognitive system in its own right. (shrink)

All other things being equal the parser favors attaching an ambiguous modifier to the most recent possible site. A plausible explanation is that locality preferences such as this arise in the service of minimizing memory costs—more distant sentential material is more difficult to reactivate than more recent material. Note that processing any sentence requires linking each new lexical item with material in the current parse. This often involves the construction of long‐distance dependencies. Under a resource‐limited view of (...) language processing, lengthy integrations should induce difficulty even in unambiguous sentences. To date there has been little direct quantitative evidence in support of this perspective. This article presents 2 self‐paced reading studies, which explore the hypothesis that dependency distance is a fundamental determinant of reading complexity in unambiguous constructions in English. The evidence suggests that the difficulty associated with integrating a new input item is heavily determined by the amount of lexical material intervening between the input item and the site of its target dependents. The patterns observed here are not straightforwardly accounted for within purely experience‐based models of complexity. Instead, this work supports the role of a memory bottleneck in language comprehension. This constraint arises because hierarchical linguistic relations must be recovered from a linear input stream.

Plessner’s Stufen des Organischen questions both the conditions of possibility as well as the consequences of a self-understanding of life. Originally written against the background of urbanisation, industrialisation and colonisation, the strength of Plessner’s work lies in his combination of an analyticalphilosophical conceptualisation, the introduction of materiality and the body as well as his historical–ethical dimension. As a re-sult of this combination, Plessner’s approach is well suited to contribute to the current inter-national discourse on the relationship of sociality and materiality. (...) This article provides an overview of the reception of Plessner in Germany and embeds his approach into current de-bates, discussing its value with regard to the sociality-materiality relationship. The focus is on three issues: the definition of the boundaries of the social, the relationship between the social and the body as well as the cultural historic-ethical situation. Finally, Plessner’s Steps of the Organic are related to the current issues of ecologisation and digitalisation, allowing us to see what a Plessnerian perspective on the materiality-sociality relationship can do with-in applied social theory.

Material culture, strictly speaking, is substance culture. Nevertheless, studies on material culture are almost exclusively concerned with things. The specificities in the perception of substances and the related everyday practices are rarely taken into consideration. Although this can be explained by the history of anthropology, the bias towards associating material culture with “formed matter” is a foundational shortcoming. In consequence, particular perspectives on the material remain understudied, and the cultural relevance of substances as such is (...) rarely taken into consideration. Taking a perspective grounded in anthropology and phenomenology, this article intends to provide new approaches to substances that elucidate the particular modes of their perception, reveal their characteristics and reflect on particular notions implicit to substances. The final section of this contribution discusses two exemplary studies on substances and proposes transformation and incorporation as new fields of research that would contribute to a more explicit engagement with substances in material culture studies.

BackgroundHuman biological materials are usually stored for possible future use in research because they preserve valuable biological information, save time and resources, which would have been spent on collection of fresh samples. However, use of these materials may pose ethical challenges such as unauthorized disclosure of genetic information, which can result in dire consequences for individuals or communities including discrimination, stigma, and psychological harm; has biosecurity implications; and loss of control or ownership of samples or data. To understand these problems (...) better, we evaluated the extent to which tuberculosis (TB) clinical research protocols that were used to collect and store biological materials for future use conform to the requirements stated in the Uganda national guidelines for research involving humans as participants.MethodsThis was a retrospective review of TB clinical research projects approved by the Uganda National Council for Science and Technology (UNCST) from 2011 to 2015, to examine whether they fulfilled the requirements for ethical collection and use of human materials. Data were abstracted through review of the project protocols using a template developed based on the informed consent and the Materials Transfer Agreement (MTA) requirements in the national guidelines.ResultsOut of 55 research protocols reviewed, most of the protocols 83.6% had been used to collect the stored samples (sputum, blood and sometimes urine), 28% had a section on specimen collection and 24% mentioned ownership of the biological materials. With respect to review of the consent forms used in the studies that stored materials for future use, only 9% of the protocols had a separate consent form for storage of materials, 4.5% of the consent forms explained the risks, 11.4% explained the purpose of the study while 6.8% mentioned the place of storage for the collected materials.ConclusionMany of the studies reviewed did not meet the requirements for collection and storage of biological materials contained in the national guidelines, which indicates a need to additional training on this topic.

Objectives: To present an analysis of “futility” that is useful in the clinical setting.Design: Literature review.Material and methods: According to Medline more than 750 articles have been published about medical futility. Three criteria singled out 43 of them. The authors' opinions about futility were analysed using the scheme: “If certain conditions are satisfied, then a particular measure is futile” and “If a particular measure is futile, then certain moral consequences are implied”.Results: Regarding conditions, most authors stated that judgments about (...) futility should be made by physicians. The measure was usually some kind of medical treatment, and the goals related to quality of life, physiological improvement, or prolongation of life. The probability of success in reaching the goal was in most cases described in semiquantitative terms. Regarding consequences, the authors stated that health care professionals may withhold or withdraw a futile measure, most often after a dialogue with the patient , but sometimes without informing the patient , or with one-way information . Over time more and more articles recommend that the patient should be involved in joint decision making. Based on this literature review a clinical model was developed.Conclusions: The model, requiring that conditions and consequences should be made explicit, may, in “futility situations”, facilitate both the collection of the necessary information and make the moral implications visible. It also makes communication about measures considered to be futile possible without using such ambiguous terms as “futile”. (shrink)

There is an overlooked similarity between three classic accounts of the conditions of object experience from three distinct disciplines. Sociology: the “inversion” that accompanies discovery in the natural sciences, as local causes of effects are reattributed to an observed object. Psychology: the “externalization” that accompanies mastery of a visual–tactile sensory substitution interface, as tactile sensations of the proximal interface are transformed into vision-like experience of a distal object. Biology: the “projection” that brings forth an animal’s Umwelt, as impressions on its (...) body’s sensory surfaces are reconfigured into perception of an external object. This similarity between the effects of scientific practice and interface-use on the one hand, and of sensorimotor interaction on the other, becomes intelligible once we accept that skillful engagement with instruments and interfaces constitutes a socio-material augmentation of our basic perceptual capacity. This enactive interpretation stands in contrast to anti-realism about science associated with constructivist interpretations of these three phenomena, which are motivated by viewing them as the internal mental construction of the experienced object. Instead, it favors a participatory realism: the sensorimotor basis of perceptual experience loops not only through our body, but also through the external world. This allows us to conceive of object experience in relational terms, i.e., as one or more subjects directly engaging with the world. Consequently, we can appreciate scientific observation in its full complexity: it is a socio-materially augmented process of becoming acquainted with the observed object that—like tool-use and perceiving more generally—is irreducibly self, other-, and world-involving.

In a previous essay we demonstrated that quantum mechanical formalism is incompatible with some necessary principles of the mechanism conception still dominant in the physicist’s community. In this paper we show, based on recent empirical evidence in quantum physics, the inevitability of abandoning the old mechanism conception and to construct a new one in which physical reality is seen as a representation which refers to relations established through operations made by us in a world that we are determining. This change (...) is profound and radical, with immediate consequences on both Ontology and Epistemology. This work is our contribution to try to make more concrete how this new conception of the world might be. (shrink)

In his classic 1936 paper Tarski sought to motivate his definition of logical consequence by appeal to the inference form: P(0), P(1), . . ., P(n), . . . therefore ∀nP(n). This is prima facie puzzling because these inferences are seemingly first-order and Tarski knew that Gödel had shown first-order proof methods to be complete, and because ∀nP(n) is not a logical consequence of P(0), P(1), . . ., P(n), . . . by Taski's proposed definition. An attempt (...) to resolve the puzzle due to Etchemendy is considered and rejected. A second attempt due to Gómez-Torrente is accepted as far as it goes, but it is argued that it raises a further puzzle of its own: it takes the plausibility of Tarski's claim that his definition captures our common concept of logical consequence to depend upon our common concept being a reductive conception. A further interpretation of what Tarski had in mind when he offered the example is proposed, using materials well known to Tarski at the time. It is argued that this interpretation makes the motivating example independent of reductive definitions which take natural numbers to be higher-order set theoretic entities, and it also explains why he did not regard the distinction between defined and primitive terms as pressing, as was the distinction between logical and nonlogical terms.

In this paper Grice's requirements for assertability are imposed on the disjunction of Classical Logic. Defining material implication in terms of negation and disjunction supplemented by assertability conditions, results in the disappearance of the most important paradoxes of material implication. The resulting consequence relation displays a very strong resemblance to Schurz's conclusion-relevant consequence relation.

We fine tune the distinction between the possible and what can be, mention some of the consequences and argue that the difference between material and logical implication is that of between what can be and what could have been.

What ultimately is the relationship of the development of scientific technology and the consequent raising of the material level of life to the development of morality? Today, as the realization of the Four Modernizations is accelerated, a thorough examination of this question is highly important and meaningful.

This paper explores whether it is possible to use Kant's writings on law and his Principle of Right to develop a theory of tort liability for the unintended harmful consequences to other persons that materialize from the wrongful risks created by human actions. The paper uses PR to identify such risks, and imputes to their authors the wrongful hindrances of other persons that result from them. PR protects the freedom of action of human agents, but it also permits them to (...) exercise that freedom by assuming or consenting to the creation of risks towards themselves, and the harms that materialize from such risks are imputed to those voluntary risk bearers. The paper also explains how PR entails both strict liability and negligence, in different domains of tort law, as standards of tort liability, so that neither of those standards is the fundamental principle of tort law; that principle, instead, appears to be the the Principle of Right. Der Beitrag untersucht, ob es möglich ist, Kants Rechtslehre und sein Allgemeines Prinzip des Rechts zu benutzen, um eine Theorie der deliktischen Haftung für Fahrlässigkeitstaten zu entwickeln. Fahrlässigkeitstaten sind rechtswidrige menschliche Handlungen, die unbeabsichtigt Gefahren für andere verursachen, durch die schädliche Folgen für diese anderen entstehen. Der Artikel benutzt das Allgemeine Prinzip des Rechts, um solche Risiken festzustellen und ihren Urhebern die daraus resultierenden rechtswidrigen Verletzungen anderer Personen zuzurechnen. Das Prinzip schützt die Handlungsfreiheit. Aber es erlaubt den handelnden Personen auch, diese ihre Freiheit auszuüben, insofern es ihnen gestattet, Risiken für sich selbst zu schaffen. Die dadurch entstehenden Schäden werden dem Handelnden auch zugerechnet, weil er die entsprechenden Gefahren freiwillig übernommen hat. Der Artikel erklärt, wie das Allgemeine Prinzip des Rechts in den verschiedenen Bereichen des Deliktsrechts bald eine Gefährdungshaftung, bald eine Haftung für Fahrlässigkeit begründet. Keiner dieser Standards enthält das eigentliche Grundprinzip des Deliktsrechts. Das Grundprinzip ist statt dessen Kants Allgemeines Prinzip des Rechts. (shrink)

In this paper, Tarskis notion of Logical Consequence is viewed as a special case of the more general notion of being a theorem of an axiomatic theory. As was recognized by Tarski, the material adequacy of his definition depends on having the distinction between logical and non logical constants right, but we find Tarskis analysis persuasive even if we dont agree on what constants are logical. This accords with the view put forward in this paper that Tarski indeed (...) captures the more inclusive notion of theoremhood in an axiomatic theory. The approach to logical consequence via axiomatic theories leads us to grant centrality to inference schemas rather than to full-fledged arguments and to view the logically valid schemas as a subclass of generally valid schemas.
