Atran argues that an autonomous ethnobiological information-processing module exists. This module imputes a “deep causal essence” to folk-biological taxa and uses a hierarchy of taxonomic ranks. I argue that Atran's own data suggest that rank is not an essential feature of the ethnobiological module, and that ethnobiological causal essences may be generalized to other domains and vice versa, limiting its autonomy.

Conventional wisdom holds that the von Neumann entropy corresponds to thermodynamic entropy, but Hemmo and Shenker (2006) have recently argued against this view by attacking von Neumann's (1955) argument. I argue that Hemmo and Shenker's arguments fail due to several misunderstandings: about statistical-mechanical and thermodynamic domains of applicability, about the nature of mixed states, and about the role of approximations in physics. As a result, their arguments fail in all cases: in the single-particle case, the finite particles case, and the (...) infinite particles case. (shrink)

In Everettian quantum mechanics, justifications for the Born rule appeal to self-locating uncertainty or decision theory. Such justifications have focused exclusively on a pure-state Everettian multiverse, represented by a wave function. Recent works in quantum foundations suggest that it is viable to consider a mixed-state Everettian multiverse, represented by a (mixed-state) density matrix. Here, we develop the conceptual foundations for decoherence and branching in a mixed-state multiverse, and extend the standard Everettian justifications for the Born rule to this setting. This (...) extended framework provides a unification of 'classical' and 'quantum' probabilities, and additional theoretical benefits, for the Everettian picture. (shrink)

[Accepted for publication in Lakatos's Undone Work: The Practical Turn and the Division of Philosophy of Mathematics and Philosophy of Science, special issue of Kriterion: Journal of Philosophy. Edited by S. Nagler, H. Pilin, and D. Sarikaya.] Lakatos’s analysis of progress and degeneration in the Methodology of Scientific Research Programmes is well-known. Less known, however, are his thoughts on degeneration in Proofs and Refutations. I propose and motivate two new criteria for degeneration based on the discussion in Proofs and Refutations (...) – superfluity and authoritarianism. I show how these criteria augment the account in Methodology of Scientific Research Programmes, providing a generalized Lakatosian account of progress and degeneration. I then apply this generalized account to a key transition point in the history of entropy – the transition to an information-theoretic interpretation of entropy – by assessing Jaynes’s 1957 paper on information theory and statistical mechanics.

Programs in quantum gravity often claim that time emerges from fundamentally timeless physics. In the semiclassical time program time arises only after approximations are taken. Here we ask what justifies taking these approximations and show that time seems to sneak in when answering this question. This raises the worry that the approach is either unjustified or circular in deriving time from no–time.

This essay presents and analyzes the recent work of four prominent contemporary Jewish ethicists: Eugene Borowitz, David Novak, Byron Sherwin, and Walter Wurzburger. These authors are united in their affirmation of covenant as the central category of Jewish moral obligation and their concern to construct a Jewish ethic out of the classical sources of Judaism. Yet, as an individual analysis of their books will show, they adopt markedly different views of the authority of traditional Jewish law , the respective roles (...) of individual and community in moral deliberation, and the degree to which changing historical circumstances alter moral truths.

Buridan’s Ass faced a choice between two identical bales of hay; governed only by reason, the donkey starved, unable to choose. It seems clear that we face many such cases, and resolve them successfully. Our success seems to tell against any view on which action and intention require evaluative preference. I argue that these views can account for intention and intentional action in cases like that of Buridan’s Ass. A decision to act nonintentionally allows us to resolve these cases without (...) their being a damaging theoretical counterexample. (shrink)

This study investigated the differences in responses of undergraduate business students to an ethical dilemma. Demographic characteristics were collected on the respondents and profiled as a means of examining common bases for decision. The authors found that certain demographic characteristics appear to be predictors of ethical decision behavior of future businessmen.

Vigorous debate over the moral propriety of cognitive enhancement exists, but the views of the public have been largely absent from the discussion. To address this gap in our knowledge, four experiments were carried out with contrastive vignettes in order to obtain quantitative data on public attitudes towards cognitive enhancement. The data collected suggest that the public is sensitive to and capable of understanding the four cardinal concerns identified by neuroethicists, and tend to cautiously accept cognitive enhancement even as they (...) recognize its potential perils. The public is biopolitically moderate, endorses both meritocratic principles and the intrinsic value of hard work, and appears to be sensitive to the salient moral issues raised in the debate. Taken together, these data suggest that public attitudes toward enhancement are sufficiently sophisticated to merit inclusion in policy deliberations, especially if we seek to align public sentiment and policy.

Eugene Marshall presents an original, systematic account of Spinoza's philosophy of mind, in which the mind is presented as an affective mechanism that, when rational, behaves as a spiritual automaton. He explores key themes in Spinoza's thought, and illuminates his philosophical and ethical project in a striking new way.

In this major contribution to philosophy and rhetoric, Eugene Garver shows how Aristotle integrates logic and virtue in his great treatise, the _Rhetoric._ He raises and answers a central question: can there be a civic art of rhetoric, an art that forms the character of citizens? By demonstrating the importance of the _Rhetoric_ for understanding current philosophical problems of practical reason, virtue, and character, Garver has written the first work to treat the _Rhetoric_ as philosophy and to connect its themes (...) with parallel problems in Aristotle's _Ethics_ and _Politics._ Garver's study will help put rhetoric at the center of investigations of practice and practical reason.

GJ: We've talked a lot about critics who are hostile toward you. Do you ever feel the need to make a stand against those who are favourably inclined toward your plays but whose comments seem to you to be stupid? EI: Well, for better or worse, that's what I've always done: I wrote Notes and Counter-Notes, had discussions with Claude Bonnefoy, I've written articles; and in each case what I've said, in short, is that critics who gave me their approval, (...) did so because they misunderstood me and were mistaken about my intentions. GJ: Finally, are you at all bitter about the critics? EI: No. Many have become good friends of mine. But it is a bit disheartening; when I began, a critic who, shall we say, is on the Right, a conservative critic who is very well-known and has since become a friend of mine, called me an impostor, a fraud, and a dummy; and now, twenty-five years later, the Leftists still call me an impostor, a fraud, and a dummy. GJ: But less often? EI: Well, I suppose so. Eugene Ionesco, renowned by playwright , recently was awarded the International Writer's Prize by the Welsh Arts Council. While in Wales, he was interviewed by Gabriel Jacobs, lecturer in French at University College of Swansea; the interview represents Ionesco's most concerted attempt yet to deal with his critics. He is completing a book on the subject which Gabriel Jacobs will translate into English. (shrink)

G.E. Moore noticed the oddity of statements like: “It's raining, but I don't believe it.” This oddity is often seen as analogous to the oddity of believing akratically, or believing what one believes one should not believe, and has been appealed to in denying the possibility of akratic belief. I describe a Belief Akratic's Paradox, analogous to Moore's paradox and centered on sentences such as: “I believe it's raining, but I shouldn't believe it.” I then defend the possibility of akratic (...) belief against appeals to this analogy, arguing both that akratic belief does not require belief-akratic-paradoxical belief, and that the latter is importantly different from Moorean belief. I conclude by considering the implications of these arguments for an understanding of both Moorean and akratic belief. (shrink)
