No international agreement has been completely effective in reducing slavery. This stems in part from the evolution of slavery agreements and the inclination on the part of the authors of conventions to include other practices as part of the slavery defintion, resulting in a confusion of the practices and definitions of slavery. What has been missing is a classification that is dynamic and yet sufficiently universal to identify slavery no matter how it evolves. We have attempted to build on theories (...) and examples to clarify the identification of slavery by focusing on an irreducible core of three elements. Assessing the presence of all three can then be applied to a variety of social relationships: first, the complete control of one personal by another; second, appropriation of labor power; and third, the enforcement of these conditoins by threats or acts of violence. Many practices identified in international agreements have some but not all of these three aspects; all three are present in traditional forms of slavery, bonded labor, forced prostitution, and sexual slavery. Effective research and legislation against slavery is important, as it affects an estimated 27 million people worldwide, and as slavery is on the increase now that many developing countries are forced to compete for income in a global economy. Finally it is important to remember that slavery, like all social and economic relationships, evolves over time. Any definition that is based on a historical form of slavery will soon lose its power to capture new forms of slavery within its aegis. Our understanding and our definition of slavery must become as dynamic as the phenomenon itself. (shrink)

Expressions like "two novels" are traditionally taken to convey information about cardinality and are analyzed using a cardinality function. Salmon (Philosop Perspect 11:1–15, 1997), Liebesman (Australasian J Philos 93:21–42, 2015; Philos’ Impr 16:1–25, 2016; In D. W. Zimmerman (ed.), Oxford studies in metaphysics, Oxford University Press, Oxford, forthcoming), and Haida and Trinh (in: Dočekal, Wagiel (eds) Formal approaches to number in Slavic and beyond, Language Science Press, Berlin, 2001) argue against this traditional account, claiming that it can’t explain our use (...) of expressions like "two and a half novels". According to them, the proper analysis of such expressions requires a partiality measure, which maps entities to rational numbers such as 2.5. In this paper, we set out to defend the traditional account. To do so, we demonstrate that an analysis based on a partiality measure is inconsistent with the truth conditions of plural comparatives and equatives. We also show that such an account doesn’t provide an adequate analysis for expressions like "two novels and a half", nor for their French counterparts (e.g., "deux romans et demi"). Critically, such expressions contain no constituent that could refer to the number 2.5. We provide an alternative analysis for all these expressions, based on cardinality and an operation of non-overlapping summation. (shrink)

Computer simulations show that an unstructured neural-network model [Shultz, T. R., & Bale, A. C. (2001). Infancy, 2, 501–536] covers the essential features␣of infant learning of simple grammars in an artificial language [Marcus, G. F., Vijayan, S., Bandi Rao, S., & Vishton, P. M. (1999). Science, 283, 77–80], and generalizes to examples both outside and inside of the range of training sentences. Knowledge-representation analyses confirm that these networks discover that duplicate words in the sentences are nearly identical and that (...) they use this near-identity relation to distinguish sentences that are consistent or inconsistent with a familiar grammar. Recent simulations that were claimed to show that this model did not really learn these grammars [Vilcu, M., & Hadley, R. F. (2005). Minds and Machines, 15, 359–382] confounded syntactic types with speech sounds and did not perform standard statistical tests of results. (shrink)

The apolipoprotein E gene plays an important role in the pathogenesis of Alzheimer's disease , and amyloid plaque comprised mostly of the amyloid-beta peptide ) is one of the major hallmarks of AD. However, the relationship between these two important molecules is poorly understood. We examined how A treatment affects APOE expression in cultured cells and tested the role of the transcription factor NF-B in APOE gene regulation. To delineate NF-B's role, we have characterized a 1098 nucleotide segment containing the (...) 5'-flanking region of the human APOE gene . Sequence analysis of this region suggests the presence of two potential NF-B elements. To demonstrate promoter activity, the region was cloned upstream of a promoterless luciferase gene. This segment was able to drive expression of luciferase in transient transfections of human fetal glial cells. Promoter activity was stimulated twofold by A treatment. Pretreatment with double-stranded DNA decoy oligonucleotides against NF-B reduced A stimulation. Deletion and mutagenetic analyses demonstrated that the distal NF-B element was functional and showed a strong DNA-protein complex band in gel shift analysis, similar to that from control NF-B consensus element. An anti-inflammatory and anti-NF-B drug, sodium salicylate, significantly blocked A-induced APOE promoter function. Our data provide evidence that upregulation of APOE by A in astroglial cells is mediated by an NF-B-element present in the 5'-flanking region of the APOE gene. (shrink)

The paradox of ’Buridan’s ass’ involves an animal facing two equally adequate and attractive alternatives, such as would happen were a hungry ass to confront two bales of hay that are equal in all respects relevant to the ass’s hunger. Of course, the ass will eat from one rather than the other, because the alternative is to starve. But why does this eating happen? What reason is operative, and what explanation can be given as to why the ass eats from, (...) say, the left bale rather than the right bale? Why doesn’t the ass remain caught between the options, forever indecisive and starving to death? Religious pluralists face a similar dilemma, a dilemma that I will argue is more difficult to address than the paradox just described. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.2 (2004) 219-220 [Access article in PDF] Jack Zupko. John Buridan: Portrait of a Fourteenth-Century Arts Master. Notre Dame: University of Notre Dame Press, 2003. Pp. xix + 446. Cloth, $70.00. Paper, $40.00. What does the name "John Buridan" call to mind? For many, including medievalists, not much at all—at best, perhaps, a set of apparently unrelated ideas: nominalism; an impetus theory of (...) projectile motion; and a peculiar account of the will (although "Buridan's ass," the indecisive donkey caught between two equally appetizing bales of hay, is not found in Buridan's writing). In correcting this ignorance—an injustice to arguably the most famous and influential philosopher of the early-to-mid-fourteenth century—the temptation might have been to articulate Buridan's "positions" on "the big questions," allowing readers to fit Buridan into received categories. Thankfully, the present work, the first book-length study of Buridan in any language, resists this temptation. The John Buridan that emerges from Jack Zupko's skillful "exercise in philosophical portraiture" doesn't serve to simply fill gaps in our awareness of the historical record, but to enlighten and challenge our understanding of the practice of philosophy and the study of its history.Zupko emphasizes throughout that Buridan was a teacher, a master of arts in Paris. Buridan's pedagogical concerns help make sense of his central work in logic. As the basis for his arts lectures, Buridan chose Peter of Spain's Summulae Logicales, but in commenting on Peter, Buridan moves beyond creative exegisis to comprehensive renovation. Buridan (c. 1300-c. 1361) naturally wanted to accommodate terminist or via moderna supposition theory; but more importantly, he wanted a logic text that would set out a general plan of philosophical inquiry, "a compendium of methods, a 'how-to' book for the philosopher" (135). Buridan thus designed his own Summulae de Dialectica as a new authoritative logic text, and Zupko persuasively argues that its "nominalism" should be understood as less a set of doctrines in theoretical logic, than a program of logical practice, an education in logic as the ars artium, the universal intellectual tool.Zupko's portrait of "Buridan's vision of the philosophical enterprise" is thus appropriately divided into two parts. The first summarizes Buridan's method as described in the individual treatises of his Summulae. The second displays the method in practice, rehearsing and evaluating some of Buridan's arguments on various subjects. Many scholars will gravitate first to the latter part, where Zupko offers important interpretations and clarifications of Buridan's views. In these chapters, Zupko helps us to appreciate, among other things: how the problem of universals served to help Buridan define the scope of philosophy (ch. 10); the philosophical modesty of Buridan's account of the intellectual soul's presence in the body (ch. 11); the relationship between Buridan's epistemology and the skepticism of his Parisian contemporary Nicholas of Autrecourt (ch. 12); the sense in which Buridan is an "empiricist," viz an epistemic naturalist and reliabilist (ch. 13); how Buridan regarded moral psychology as applied physics, treating virtue as a kind of impetus (ch. 14); how Buridan's account of freedom can be regarded as a "perfection" of Thomistic intellectualism (ch. 15).Throughout these discussions, Zupko always keeps in sight his larger purpose of illustrating Buridan's conception of philosophical inquiry. Zupko makes much of the fact that [End Page 219] Buridan never wrote as a theologian, remaining his entire career in the arts faculty, where he wanted logic to organize secular inquiry. As Zupko notes, in this way Buridan's scholastic project seems to prefigure the "modern." But Buridan seems modern in another way as well. As Zupko points out in his "Introduction," though a cleric, Buridan never joined a religious order, so that his ideas developed independently of the Franciscan and Dominican traditions. He was, then, a teacher without a tradition—at least without deliberate allegiance to tradition, although he was in many ways the product of traditional scholastic intellectual discipline.Perhaps this...

In lieu of an abstract, here is a brief excerpt of the content:Cardboard Houses with Wings:The Architecture of Alabama's Rural StudioThorsten Botz-Bornstein (bio)IntroductionThe Rural Studio, which was founded by Samuel Mockbee in 1992 and lead by him until his death in 2001, continues its activities. Its specialty is, now as before, the design of innovative houses for poor people living in Alabama's second-poorest county, Hale County, by relying largely on donated and salvaged materials. The houses are made of car windshields, (...) surplus carpet tiles, baled cardboard, old street signs, license plates, etc. Alexis de Tocqueville has said that democracy lowers the standards of creation,1 and it seems that, for architecture, this has become a sad truth in many cases in industrialized countries. The Rural Studio wants to contradict this tendency by showing that even within the context of civic engagement, elements like style and art are not bound to disappear. "Participatory design" as well as "community design" are common in the United States in the public as well as in the private sector.2 The Rural Studio's aim to offer decent architecture in terms of material quality as well as remain consistent when it comes to aesthetics sticks out of the landscape not only of community design but even the history of modern Western architecture. There is nothing new in reducing rich people's lives to functionalism, but the ambition to enhance poor people's lives through art can still be considered as rather eccentric.Kitsch Culture and Junk CultureNegotiating style when being engaged in compassionate projects is certainly a difficult task. Everybody needs food, clothing, and shelter, but who needs [End Page 16] art? The worst outcome that such negotiations can have is, of course, the victory of social pragmatism over art, simply declaring that "they don't need that." However, this is not the only miscarriage to be expected. Another likely disaster is that the suggested artistic activity will be refused by the clients at the onset. Community design architects confirm that "when it comes to houses people are much more conservative."3 The aesthetic standards of the lower middle class especially are often determined by numerous prejudices about "what a house should look like."The aesthetic standards of the status-seeking middle class, however, are generally more open, as their visions of an ideal house are often determined by a moderately adventurous hedonism striving to conquer new aesthetic models and experiences. The problem is that, sometimes, their projects will run directly into the aesthetic dead end of kitsch, or camp, because their openness is often superficial; instead of being determined by a kind of postmodern self-criticism, it remains rather dependent on thoughtless consumer attitudes. The desire to display and impress at any cost—a strain already put forward by Tocqueville—corrupts the taste of many American middle-class members and makes truly artistic architectural expressions oftentimes impossible. In the worst case, this attitude will be conducive to the desire to "acquire beautiful junk," which is, according to the aesthetician Matei Calinescu, the classical mechanism leading to the creation of kitsch culture.4 The original German definition of "kitsch" is that "which makes use of refuse taken bodily from the rubbish dump."5The architects of the Rural Studio use predominantly junk, which forces us to consider the question: How do they manage to escape the aesthetics of kitsch? From a historical perspective, kitsch culture is the product of the European middle classes (though it has also constantly been imitated by lower-income classes). It becomes clear that the Rural Studio operates on a completely different anthropological ground. The typical clients of the Rural Studio are not integrated in the spectrum of capitalist societies, as their social habitus eludes most attributes of hedonistic consumer society and comes amazingly close to that of traditional, precapitalist societies. The main characteristics of their economies are frugality and thriftiness. This shows that the success of the Rural Studio depends on the particularity of its place: only within the limited social sphere in which they act can an architecture using junk and waste become a distinct style.It is well known that elements of waste, once they are employed in an artistic context...

Recent progress in artificial intelligence (AI) has drawn attention to the technology’s transformative potential, including what some see as its prospects for causing large-scale harm. We review two influential arguments purporting to show how AI could pose catastrophic risks. The first argument — the Problem of Power-Seeking — claims that, under certain assumptions, advanced AI systems are likely to engage in dangerous power-seeking behavior in pursuit of their goals. We review reasons for thinking that AI systems might seek power, that (...) they might obtain it, that this could lead to catastrophe, and that we might build and deploy such systems anyway. The second argument claims that the development of human-level AI will unlock rapid further progress, culminating in AI systems far more capable than any human — this is the Singularity Hypothesis. Power-seeking behavior on the part of such systems might be particularly dangerous. We discuss a variety of objections to both arguments and conclude by assessing the state of the debate. (shrink)

Orthodox decision theory gives no advice to agents who hold two goods to be incommensurate in value because such agents will have incomplete preferences. According to standard treatments, rationality requires complete preferences, so such agents are irrational. Experience shows, however, that incomplete preferences are ubiquitous in ordinary life. In this paper, we aim to do two things: (1) show that there is a good case for revising decision theory so as to allow it to apply non-vacuously to agents with incomplete (...) preferences, and (2) to identify one substantive criterion that any such non-standard decision theory must obey. Our criterion, Competitiveness, is a weaker version of a dominance principle. Despite its modesty, Competitiveness is incompatible with prospectism, a recently developed decision theory for agents with incomplete preferences. We spend the final part of the paper showing why Competitiveness should be retained, and prospectism rejected. (shrink)

A simple argument suggests that we can fruitfully model advanced AI systems using expected utility theory. According to this argument, an agent will need to act as if maximising expected utility if they’re to avoid exploitation. Insofar as we should expect advanced AI to avoid exploitation, it follows that we should expected advanced AI to act as if maximising expected utility. I spell out this argument more carefully and demonstrate that it fails, but show that the manner of its failure (...) is instructive: in exploring the argument, we gain insight into how to model advanced AI systems.

Comparative constructions form two classes, those that permit direct comparisons (comparisons of measurements as in Seymour is taller than he is wide) and those that only allow indirect comparisons (comparisons of relative positions on separate scales as in Esme is more beautiful than Einstein is intelligent). In contrast with other semantic theories, this paper proposes that the interpretation of the comparative morpheme remains the same whether it appears in sentences that compare individuals directly or indirectly. To develop a unified account, (...) I suggest that all comparisons (whether in terms of height, intelligence or beauty) involve a scale of universal degrees that are isomorphic to the rational (fractional) numbers between 0 and 1. Crucial to a unified treatment, the connection between the individuals being compared and universal degrees involves two steps. First individuals are mapped to a value on a primary scale that ranks individuals with respect to the gradable property (whether it be height, beauty or intelligence). Second, the value on the primary scale is mapped to a universal degree that encodes the value’s relative position on the primary scale. Direct comparison results if measurements such as seven feet participate in the primary scale (as in Seven feet is tall). Otherwise the result is an indirect comparison. (shrink)

Marcus et al.’s experiment (1999) concerning infant ability to distinguish between differing syntactic structures has prompted connectionists to strive to show that certain types of neural networks can mimic the infants’ results. In this paper we take a closer look at two such attempts: Shultz and Bale [Shultz, T.R. and Bale, A.C. (2001), Infancy 2, pp. 501–536] Altmann and Dienes [Altmann, G.T.M. and Dienes, Z. (1999) Science 248, p. 875a]. We were not only interested in how well these (...) two models matched the infants’ results, but also whether they were genuinely learning the grammars involved in this process. After performing an extensive set of experiments, we found that, at first blush, Shultz and Bale’s model (2001) replicated the infant’s known data, but the model largely failed to learn the grammars. We also found serious problems with Altmann and Dienes’ model (1999), which fell short of matching any of the infant’s results and of learning the syntactic structure of the input patterns. (shrink)

This paper discusses comparison classes—sets that relativize the interpretation of gradable adjectives, often specified with for-clauses as in John is smart for a linguist. Such a discussion ultimately lends support to the thesis that scales, degrees, measure functions, and linear orders are grammatically derived from more basic relations between individuals. Three accounts of comparison classes are compared and evaluated. The first proposes that such classes serve as an argument to a function that determines a standard of comparison. The second maintains (...) that these classes restrict the domain of a measure function used to map entities to degrees. The third proposes that these classes limit the kind of individuals that participate in a binary relation; this relation is then used in the construction of a scale and a measure function. It is this third account that is most consistent with the empirical data. It can explain how comparison classes fix a standard of comparison, induce presuppositions concerning the comparative subjects, and induce incommensurability in comparative constructions. (shrink)

Andy Egan has recently presented a prominent objection to causal decision theory. However, in this paper, I argue that this objection fails if CDT’s proponent accepts the plausible view that decision-theoretic options are intentions. This result both provides a defence of CDT against a prominent objection and highlights the importance of resolving the nature of decision-theoretic options.

In a letter to Wlodek Rabinowicz, David Lewis introduced a decision scenario that he described as “much more problematic for decision theory than the Newcomb Problems”. This scenario, which involves an agent with foreknowledge of the outcome of some chance process, has received little subsequent attention. However, in one of the small number of discussions of such cases, Huw Price's Causation, Chance and the Rational Significance of Supernatural Evidence it has been argued that cases of this sort pose serious problems (...) for causal decision theory. In this paper, I will argue that these problems can be overcome: scenarios of this sort do not pose fatal problems for this theory as there are versions of CDT that reason appropriately in these cases. However, I will also argue that such cases push us toward a particular version of CDT developed by Wlodek Rabinowicz. (shrink)

A prominent philosophical debate concerns whether we should accept causal decision theory or evidential decision theory as our best theory of rational choice. However, instead of accepting one of these theories at the expense of the other, an alternative would be to accept that both theories play a partial role in the true account of rational choice. In this paper, I defend a pluralist account of this sort. In particular, I argue that rational permissibility is an indeterminate notion, with EDT (...) and CDT each corresponding to one sharpening of this notion. (shrink)

Causal decision theory is one of our most prominent theories of rational choice and the “why ain’cha rich?” argument is one of the most prominent objections to this theory. According to WAR, CDT is not an adequate theory of rational choice because it leads agents to make decisions that foreseeably leave them less well off than agents that decide in some other manner. Some philosophers take WAR to decisively undermine CDT. On the other hand, others take WAR to fail to (...) resolve the debate over CDT’s adequacy. In this paper, I will defend this second view: WAR does not resolve the debate at hand but instead leads to deadlock. Then, in the second half of this paper, I will show that this deadlock is not broken by a recent variant on WAR due to Caspar Hare and Brian Hedden. Not only does this result have implications for the debate over CDT’s adequacy but this discussion also casts light on the broader success/rationality link. (shrink)

Various people have claimed that some cases involve indeterminate permissibility. However, it’s unclear what guidance one can take away from this fact: are indeterminately permissible options choiceworthy and if so when? In this paper, I present a counterexample that undermines two existing responses to this question and I then present two alternative solutions that avoid this counterexample.

Some take seriously the possibility of artificial intelligence (AI) takeover, where AI systems seize power in a way that leads to human disempowerment. Assessing the likelihood of takeover requires answering empirical questions about the future of AI technologies and the context in which AI will operate. In many cases, philosophers are poorly placed to answer these questions. However, some prior questions are more amenable to philosophical techniques. What does it mean to speak of AI empowerment and human disempowerment? And what (...) empirical claims must hold for the former to lead to the latter? In this paper, I address these questions, providing foundations for further evaluation of the likelihood of takeover. (shrink)

Why should we typically act in accordance with our resolutions when faced with the temptation to do otherwise? A much-maligned view suggests that we should do so because resolutions themselves provide us with reasons for action. We defend a version of this view, on which resolutions provide second-order reasons. This account avoids the objections typically taken to be fatal for the view that resolutions are reasons, including the prominent bootstrapping objections.

In the so-called reverse proportional reading :53, 1997), the truth conditions of statements of the form many/few \\ appear to make reference to the ratio of the individuals that are in the extensions of both \ and \ to the individuals that are in the extension of \. The analysis of such readings is controversial. One prominent approach assumes they are a symptom of many and few making reference to a context dependent standard of comparison. We observe that this initially (...) attractive approach systematically undergenerates, failing to capture pervasive reverse proportionality in environments that remove context dependency of the standard. Instead, we propose that reverse proportionality in such cases can arise from the underspecification of the measure function underlying the meanings of many and few. (shrink)

Morally supererogatory acts are those that go above and beyond the call of duty. More specifically: they are acts that, on any individual occasion, are good to do and also both permissible to do and permissible to refrain from doing. We challenge the way in which discussions of supererogation typically consider our choices and actions in isolation. Instead we consider sequences of supererogatory acts and omissions and show that some such sequences are themselves problematic. This gives rise to the following (...) puzzle: what problem can we have with a sequences of actions if each individual act or omission is itself permissible? In this paper, we develop a response to this question, by exploring whether solutions analogous to those proposed in the rational choice literature are available in the case of supererogatory sequences. Our investigation leads us to the view that making sense of the supererogatory requires accepting that there are global moral norms that apply to sequences of acts alongside the local moral norms that apply to individual acts.

In this examination of the practical and ethical implications of slave redemption the authors deal with questions such as: Does redeeming slaves actually increase the demand for -and so the number of- slaves? And what about cases where it is far from clear that redemption will improve the material condition or increase the real freedom, of a slave?

In recent years, act-utilitarianism has been distinguished from rule-utilitarianism. We may say that act-utilitarianism is the thesis that a particular act is right if and only if its utility – that is contribution towards intrinsically good states of affairs – is no less than that of some alternative act. Rule-utilitarianism is the thesis that an act is right if and only if it conforms to a rule somehow grounded in utility. The present paper concerns one type of argument sometimes used (...) as an attempt to show that act-utilitarianism cannot be an adequate ethical theory. Arguments of this type are characterized by an emphasis on practical difficulties involved in, or paradoxes arising out of, the attempt to apply act-utilitarianism theory to concrete moral situations.

Dual labor market theory, developed as an explanation of underemployment and poverty within the economy, may also be applied to the illicit economy of crime. Criminal careers are differentiated into a primary sector, with occupational stability, low failure rate, and high chances of advancement; and a secondary sector, with instability, high failure rate, and lack of "market" control. The attraction of criminal careers, the likelihood of incarceration, and the effects of law enforcement are best understood in these contexts.

A response to hector-neri castaneda's "a problem for utilitarianism" ("analysis" 28 (1968), pp. 141-142). by applying castaneda's line of argument to a theory sometimes suggested as an elaboration of ross's theory of prima facie duties, i show that if castaneda's is indeed a problem for utilitarianism, it is a problem for some deontological theories as well.
