A number of philosophers have offered quasi-perceptual theories of desire, according to which to desire something is roughly to “see” it as having value or providing reasons. These are offered as alternatives to the more traditional Humean Theory of Motivation, which denies that desires have a representational aspect. This paper examines the various considerations offered by advocates to motivate quasi-perceptualism. It argues that Humeanism is in fact able to explain the same data that the quasi-perceptualist can explain, and in one (...) case the Humean explanation is superior. Quasi-perceptual accounts of desire, the paper concludes, are for the most part unmotivated. (shrink)

The problem known as Buridan’s Ass says that a hungry donkey equipoised between two identical bales of hay will starve to death. Indecision kills the ass. Some philosophers worry about human analogs. Computer scientists since the 1960s have known about the computer versions of such cases. From what Leslie Lamport calls ‘Buridan’s Principle’—a discrete decision based on a continuous range of input-values cannot be made in a bounded time—it follows that the possibilities for human analogs of Buridan’s Ass are far (...) more wide-ranging and securely provable than has been acknowledged in philosophy. We are never necessarily decisive. This is mathematically provable. I explore four consequences: first, increased interest of the literature’s solutions to Buridan’s Ass; second, a new asymmetry between responsibility for omissions and responsibility for actions; third, clarification of the standard account of akrasia; and, fourth, clarification of the role of credences in normative decision-theory.

Moore’s paradox, the infamous felt bizarreness of sincerely uttering something of the form “I believe grass is green, but it ain’t”—has attracted a lot of attention since its original discovery (Moore 1942). It is often taken to be a paradox of belief—in the sense that the locus of the inconsistency is the beliefs of someone who so sincerely utters. This claim has been labeled as the priority thesis: If you have an explanation of why a putative content could not be (...) coherently believed, you thereby have an explanation of why it cannot be coherently asserted. (Shoemaker 1995). The priority thesis, however, is insufficient to give a general explanation of Moore-paradoxical phenomena and, moreover, it’s false. I demonstrate this, then show how to give a commitment-theoretic account of Moore Paradoxicality, drawing on work by Bach and Harnish. The resulting account has the virtue of explaining not only cases of pragmatic incoherence involving assertions, but also cases of cognate incoherence arising for other speech acts, such as promising, guaranteeing, ordering, and the like.

The paper presents a positive argument for a version of metaphysically light ethical non-naturalism from the nature of mental states such as desires. It uses as its premise the time-honoured, and recently rediscovered, doctrine of the guise of the good, whereby it is essential to desire that the object of desire be conceived as good or as normatively favoured under some description. The argument is that if the guise of the good is a correct theory of desire, then a certain (...) version of non-naturalism is better placed than other meta-ethical views to make sense of it. First I define ethical non-naturalism and the guise of the good, providing also an initial defence of the latter. Then I briefly survey some historical precedents and proceed to the argument. For each major meta-ethical view I consider I offer reasons why combining them with the guise of the good leads to consequences that are or should be unwelcome by the guise of the good. At the end of this elimination process a form of relatively metaphysically light non-naturalism will emerge as the view that best fits with the guise of the good. (shrink)

It is undeniable that human agents sometimes act badly, and it seems that they sometimes pursue bad things simply because they are bad. This latter phenomenon has often been taken to provide counterexamples to views according to which we always act under the guise of the good. This paper identifies several distinct arguments in favour of the possibility that one can act under the guise of the bad. GG seems to face more serious difficulties when trying to answer three different, (...) but related, arguments for the possibility of acting under the guise of the bad. The main strategies available to answer these objections end up either undermining the motivation for GG or failing to do full justice to the nature of perverse motivation. However, these difficulties turn out to be generated by focusing on a particular version of GG, what I call the “content version”. But we have independent reasons to prefer a different version of GG; namely, the “attitude version”. The attitude version allows for a much richer understanding of the possibility of acting on what we conceive to be bad. Drawing on an analogy with theoretical akrasia and theoretical perversion, I try to show how the attitude version can provide a compelling account of perverse actions. (shrink)
