Huw Price has argued that naturalistic philosophy inevitably leads to a deflationary approach to ontological questions. In this paper, I rebut these arguments. A more substantive, less language-focused approach to metaphysics remains open to naturalists. However, rebutting one of Price’s main arguments requires rejecting Quine’s criterion of ontological commitment. So, even though Price’s argument is unsound, it reveals that naturalists cannot rest content with broadly Quinean, “mainstream metaphysics,” which, I suggest, naturalists also have independent reasons to reject.

This paper draws on work in the sciences of the mind to cast doubt on some assumptions that have often been made in the study of self-control. Contra a long, Aristotelian tradition, recent evidence suggests that highly self-controlled individuals do not have a trait very similar to continence: they experience relatively few desires that conflict with their evaluative judgments and are not especially good at directly and effortfully inhibiting such desires. Similarly, several recent studies have failed to support the view (...) that self-control capacities are constituted, at least in part, by excellent inhibitory executive function ability. I propose an alternative “indirect harmony” hypothesis about trait self-control. According to this hypothesis, if there is a character trait of being highly self-controlled, it consists in motivational harmony within the mind that is brought about through the effective use of indirect resistance strategies that prevent occurrent motivational conflict from emerging in the first place. If this hypothesis is correct, high trait self-control in actual humans does not fit neatly into the traditional categories of either continence or temperance. I conclude by drawing out several implications this hypothesis has for future research on trait self-control and its relation to executive functions. (shrink)

There are a number of competing psychological accounts of the placebo effect, and much of the recent debate centers on the relative importance of classical conditioning and conscious beliefs. In this paper, I discuss apparent problems with these accounts and with?disjunctive? accounts that deny that placebo effects can be given a unified psychological explanation. The fact that some placebo effects seem to be mediated by cognitive states with content that is consciously inaccessible and inferentially isolated from a subject's beliefs motivates (...) an account of the placebo effect in terms of subdoxastic cognitive states. I propose that aliefs, subdoxastic cognitive states that are associative, automatic, and arational, can provide a unified psychological account of the placebo effect. This account also has the potential to illuminate interesting connections to other psychological phenomena. (shrink)

In this paper I return to the mid-20th-century debate between Quine and Carnap on the status of metaphysics questions with an eye toward advancing contemporary debates about whether naturalists can coherently undertake substantive metaphysical inquiry. Following Huw Price, I take the debate between Quine and Carnap to hinge, in part, on whether human inquiry is functionally unified. However, unlike Price, I suggest that this question is not best understood as a question about the function(s) of descriptive discourse. This goes along (...) with rejecting a “linguistic conception” of the starting point of metaphysical inquiry, which, although shared by Quine and Carnap, Price gives us no good reason to think is mandatory for naturalists. I sketch two reasons naturalists have to reject a particular manifestation of this linguistic conception in Quine’s work—his criterion of ontological commitment. Finally, I show how these reasons can help us identify the grains of truth in some recent critiques of “mainstream metaphysics of mind.”. (shrink)

A neo-Aristotelian approach to self-control has dominated both philosophy and the sciences of the mind. This approach endorses three key theses: that self-control is a form of self-regulation aimed at desires that conflict with one’s evaluative judgments, that high trait self-control is continence, which is distinguished from temperance by motivational conflict, and that self-control is broad, in that such resistance can be not only direct but also indirect. There is an obvious tension between and. I argue that the equally obvious (...) resolution of this tension—allowing that self-control does not require occurrent conflicting desires but can instead be aimed at foreseeable conflicting desires—reveals a surprisingly unnoticed tension between and. To resolve this tension, we are forced to either deny that high trait self-control is continence or deny that self-control is broad. If self-control is narrow, recent empirical evidence suggests that it may not be a good candidate for a human excellence concerning self-regulation. Thus, if we want to make room for such an excellence, we may need to deny that high trait self-control is continence. However we resolve these tensions, the Aristotelian status quo regarding self-control cannot stand. (shrink)

According to many virtue ethicists, one of Aristotle’s important achievements was drawing a clear, qualitative distinction between the character traits of temperance and self-control. In an influential series of papers, John McDowell has argued that a clear distinction between temperance and self-control can be maintained only if one claims that, for the virtuous individual, considerations in favor of actions that are contrary to virtue are “silenced.” Some virtue ethicists reject McDowell’s silencing view as offering an implausible or inappropriate picture of (...) human virtue, but they argue that virtue can still be clearly distinguished from self-control by the absence of motivational conflict alone. In this paper, I argue that this criticism of McDowell is at most half right. If the silencing view is false, so that virtue can have a cost and the virtuous person can justifiably feel negative emotions in response to that cost, there is no principled reason why the virtuous person cannot also have motivational conflict. So, if one rejects the silencing view, then one must allow that the distinction between virtue and self-control is at most a matter of degree. (shrink)

A gas in a box is perhaps the most important model system studied in thermodynamics and statistical mechanics. Usually, studies focus on the gas, whereas the box merely serves as an idealized confinement. The present article focuses on the box as the central object and develops a thermodynamic theory by treating the geometric degrees of freedom of the box as the degrees of freedom of a thermodynamic system. Applying standard mathematical methods to the thermody- namics of an empty box allows (...) equations with the same structure as those of cosmology and classical and quantum mechanics to be derived. The simple model system of an empty box is shown to have interesting connections to classical mechanics, special relativity, and quantum field theory. (shrink)
