In Ruling Passions, Simon Blackburn contends that we should reject sensibility theory because it serves to support a conservative complacency. Blackburn's strategy is attractive in that it seeks to win this metaethical dispute – which ultimately stems from a deep disagreement over antireductionism – on the basis of an uncontroversial normative consideration. Therefore, Blackburn seems to offer an easy solution to an apparently intractable debate. We will show, however, that Blackburn's argument against sensibility theory does not succeed; it is no (...) more supportive of conservative complacency than Blackburn's noncognitivism. A victory for noncognitivism cannot be so easily won. (shrink)

The metatethical position known as motive internalism (MI) holds that moral beliefs are necessarily motivating. Adina Roskies (in Philosophical Psychology, 16) has recently argued against MI by citing patients with injuries to the ventromedial (VM) cortex as counterexamples to MI. Roskies claims that not only do these patients not act in accordance with their professed moral beliefs, they exhibit no physiological or affective evidence of being motivated by these beliefs. I argue that Roskies' attempt to falsify MI is unpersuasive because (...) the evidence used to attribute the relevant moral beliefs to VM patients is insufficient: Contra Roskies, that VM patients are proficient moral reasoners does not establish the presence of these moral beliefs. In addition, the linguistic evidence Roskies cites (a) is vulnerable to methodological worries about its reliability or authenticity, (b) does not override counterevidence derived from the patients' nonlinguistic behavior, and (c) is undermined by VM patients' inability to correctly attribute moral beliefs to others. I conclude with a proposal about how MI should be interpreted, given that it is not falsified by empirical evidence of the sort put forth by Roskies. (shrink)

In this paper, I analyze the concept of a besire. I argue that distinguishing between different types and interpretations of besires is a critical tool for adequately assessing besire theories of moral judgment. I argue for this by applying the results of this conceptual analysis of a besire to David Brink’s version of the moral problem and to objections against besire theories made by Michael Smith, Simon Blackburn, and Nick Zangwill.

My dissertation addresses the question "do desires provide reasons?" I present two independent lines of argument in support of the conclusion that they do not. The first line of argument emerges from the way I circumscribe the concept of a desire. Complications aside, I conceive of a desire as a member of a family of attitudes that have imperative content, understood as content that displays doability-conditions rather than truth-conditions. Moreover, I hold that an attitude may provide reasons only if it (...) has truth-evaluable content. Insofar as desires lack truth-evaluable content, I hold that the content of a desire has the wrong kind of logical structure to provide reasons. My second line of argument claims that even if a desire did have truth-evaluable content, it would not follow that desires provide reasons. This is because a desire has no more rational significance than a guess or coin-flip. My argument relies on what I call the non-substitutability principle, the thesis that (all things being equal) one cannot substitute something that lacks rational significance, relative to some attitude, A, for something that has rational significance, relative to A, and leave the rational standing of A unchanged. For example, one cannot substitute the guess that P (i.e., something that lacks rational significance relative to the belief that P) for the perception that P (i.e., something that is rationally significant relative to the belief that P) without altering the rational standing of the belief. I argue that when the non-substitutability principle is applied to a desire that gives rise to an intention, it turns out that one can always substitute a guess or coin-flip (i.e., something that lacks rational significance relative to the intention) for the desire, without altering the rational standing of the intention. I take this to show that desires are not rationally significant relative to the intentions to which they give. (shrink)

I believe that normative force depends on desire. This view faces serious difficulties, however, and has yet to be vindicated. This paper sketches an Argument from Voluntary Response, attempting to establish this dependence of normativity on desire by appeal to the autonomous character of our experience of normative authority, and the voluntary character of our responses to it. I first offer an account of desiring as mentally aiming intrinsically at some end. I then argue that behaviour is only voluntary if (...) it results from such aiming; hence all voluntary behaviour is produced by desire. Full-blooded responses to normativity, I then argue, are voluntary actions: motivation to act arises voluntarily from perception of reasons to act. This fits the desire-based model of normativity but not its rivals. However this argument concludes merely that our responses to normativity are desire-based. I end with some observations about how I think we can bridge the gap from the nature of response to normativity to the nature of normativity itself. (shrink)
