What I have tried to do is elicit and disarm the motivations most likely to give rise to the [counterexamples to the principle crucial to Williams' argument]. Only one of these motivations is still viable: the instrumentalist theory of practical reasoning. But because internalism and instrumentalism are, as it has turned out, so very tightly linked, in disarming the motivations for the objection, I have also inventoried, and given reason to reject, what I have found to be the most common conversationally adduced defences of instrumentalism: the appeals to imagination, to dispositional desires, and so on. The issue remaining from the debate over internalism turns out to be whether [instrumentalism is false---i.e. whether] there are patterns of practical inference that are not directed toward the satisfaction of desire.

Hume’s examination of the conventions of property, trade, and contract addresses the moral foundations that make business possible. In this light, Hume’s theory of justice is also a foundational work in business ethics. In Hume’s analysis of these conventions, both philosophers and game theorists have correctly identified “proto” game-theoretic elements. One of the few attempts to offer a Humean theory of business ethics rests on this game-theoretic interpretation of Hume’s argument. This article argues that game-theoretic reasoning is only one part of a Humean business ethics and this can be shown by further analyzing Hume’s theory of justice. As we examine his theory, it becomes clear that Hume is not trying to show how it is always rational to respect the rules of business. Hume is not engaging in, or attempting, a reconciliation project and neither is a Humean business ethics. The final section of the article is a brief Humean analysis of the effectiveness of codes of ethics. The purpose of this section is not to decide the issue but to show how a Humean approach is both useful, relevant, and involves more than reconciling rationality and morality.

A naturalistic project descended from Hume seeks to explain „ought‟ and normativity as a product of motivational states such as desires and aversions.2 Following Kant, rationalists reject this thesis, holding that „ought‟ rather expresses a command of reason or intellect independent of desires. On Hume‟s view the only genuine form of practical reason is theoretical reason operating in the service of desire, as in calculation of means to ends. Reason at most discovers normative requirements, which exist through the interrelation of subjective desires and objective world. The Humean desiredependence view of the source of normativity is commonly associated with instrumentalism, an influential theory of normative content according to which agents ought always and only to act so as to optimize satisfaction of their own desires. But rationalists (including Thomas Nagel, Jean Hampton, and Christine Korsgaard) have recently argued that proponents of desire-dependence are not entitled even to this instrumentalist „ought.‟3 Instrumentalism holds that all normativity derives from the instrumental norm: approximately, the principle that one ought to take the means to one‟s ends, or..

The present essay offers a sketch of a philosophy of value, what I shall here refer to as ‘ethical instrumentalism.’ My primary aim is to say just what this view involves and what its commitments are. In the course of doing so, I find it necessary to distinguish this view from another with which it shares a common basis and which, in reference to its most influential proponent, I refer to as ‘Humeanism.’ A second, more general, aim is to make plausible the idea that, given the common basis, ethical instrumentalism provides a more compelling picture of the philosophy of value than Humeanism does.

Humean instrumentalism is the view that all of one’s reasons for action are ultimately grounded in one’s antecedent desires, whatever those happen to be. According to this view, what determines which actions are rational is ultimately what the agent wants or desires, while the role of rational deliberation is to inform the agent about how to best gratify these desires. In this paper I aim to weaken commitment to Humean instrumentalism by showing that (a) the main supporting argument for HI fails and that (b) Humean instrumentalism conflicts with a very plausible principle of practical rationality.

This is an age of naturalization projects. Much epistemological work has been done toward naturalizing theoretical reason. One might view Hume as seeking to naturalize reason in both the theoretical (roughly, epistemological) and the practical realms. I suggest that whatever else underlies the vitality of Hume's instrumentalism - encapsulated in his view that 'reason is and ought only to be the slave of the passions' - one incentive is the hope of naturalizing practical reason. This paper explores some broadly Humean versions of instrumentalism that are among the most plausible contenders to represent instrumentalism as a contemporary naturalistic position. It first offers a taxonomy of reasons for action and, in that light, formulates a plausible version of instrumentalism. It then raises difficulties for the view, some of them concerning the nature of desire. It also develops an epistemologically significant comparison of desires with beliefs. Given the magnitude of the difficulties, it outlines an alternative account of practical reason.

Many believe that the rational evaluation of actions depends on the rational evaluation of even basic desires. Hume, though, viewed desires as "original existences" which cannot be contrary to either truth or reason. Contemporary critics of Hume, including Norman, Brandt and Parfit, have sought a basis for the rational evaluation of desires that would deny some basic desires reason-giving force. I side with Hume against these modern critics. Hume's concept of rational evaluation is admittedly too narrow; even basic desires are, despite their nonrepresentational nature, subject to rational evaluation. But this evaluation is not relevant to their tendency to generate reasons for action, and does not undermine the spirit of the Humean view of rational action.

I introduce a distinction between two divergent trends in the literature on Hume and practical reason. One trend, action-theoretic Humeanism, primarily concerns itself with defending a general account of reasons for acting. The other trend, virtue-theoretic Humeanism, concentrates on defending the case for being an agent of a particular practical character, one whose enduring dispositions of practical thought are virtuous. I discuss work exemplifying these two trends and warn against decoupling thought about Hume's and a Humean theory of practical reason from Hume's and a Humean ethics. I conclude that the virtue-theoretic approach is a fruitful one for pursuing future work on Hume and Humeanism about practical reason.
