PEGS, BOARDS, AND RELATIVISTIC PERDURANCE

In an earlier work I developed an argument favoring one view of persistence (viz., perdurance) over its rivals, based on considerations of the relativity of three-dimensional spatial shapes of physical objects in Minkowski spacetime. The argument has since come under criticism (in the works of Theodore Sider, Kristie Miller, Ian Gibson, Oliver Pooley, and Thomas Sattig). Two related topics, explanatory virtues and explanatory relevance, are central to these critical discussions. In this paper I deal with these topics directly and respond to my critics by offering a new perspective on the issue.     

ON THE RATIONALIST SOLUTION TO GREGORY KAVKA'S TOXIN PUZZLE

Gregory Kavka's 'Toxin Puzzle' suggests that I cannot intend to perform a counter-preferential action A even if I have a strong self-interested reason to form this intention. The 'Rationalist Solution,' however, suggests that I can form this intention. For even though it is counter-preferential, A-ing is actually rational given that the intention behind it is rational. Two arguments are offered for this proposition that the rationality of the intention to A transfers to A-ing itself: the 'Self-Promise Argument' and David Gauthier's 'Rational Self-Interest Argument.' But both arguments – and therefore the Rationalist Solution – fail. The Self-Promise Argument fails because my intention to A does not constitute a promise to myself that I am obligated to honor. And Gauthier's Rational Self-Interest Argument fails to rule out the possibility of rational irrationality.     

PERCEPTUAL PRESENCE

Plausibly, any adequate theory of perception must (a) solve what Alva Noë calls 'the problem of perceptual presence,' and (b) do justice to the direct realist idea that what is given in perception are garden-variety spatiotemporal particulars. This paper shows that, while Noë's sensorimotor view arguably satisfies the first of these conditions, it does not satisfy the second. Moreover, Noë is wrong to think that a naïve realist approach to perception cannot handle the problem of perceptual presence. Section three of this paper develops a version of naïve realism that meets both of the adequacy conditions above. This paper thus provides strong considerations in favor of naïve realism.

Enhancing Authenticity

Some philosophers have criticized the use of psychopharmaceuticals on the grounds that even if these drugs enhance the person using them, they threaten their authenticity. Others have replied by pointing out that the conception of authenticity upon which this argument rests is contestable; on a rival conception, psychopharmaceuticals might be used to enhance our authenticity. Since, however, it is difficult to decide between these competing conceptions of authenticity, the debate seems to end in a stalemate. I suggest that we need not resolve this debate to end the stalemate. New technologies which alter the self can be understood within the framework of the first conception of authenticity, I suggest, not as threatening the authentic self, but rather as bringing the outward appearance of the self into line with its deepest essence. Since psychopharmaceutical use can plausibly be understood on this model, it can be seen as enhancing our authenticity on either conception.
