Blumberg and Holguín present two puzzles regarding the semantics of attitude reports involving conditionals (ie. Attitude-Conditionals) which seem to involve commitments to assertions which entail contradictions, and take this data to call for a revision of our semantics for Attitude-Conditionals. This paper attempts to resolve the puzzles without radically revising our semantics for conditionals. (This is a work in progress. Please ask before citing/circulating.).

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.

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)

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)

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.

[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.

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.

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.
