I hope to demonstrate the value of a close reading Williams’s ‘Internal and External Reasons’, and to provide a theory of error regarding the substantial body of work which seeks to, in various ways, defang the essay. I do this by providing some historical context for the paper, and sketching where, historically, internalism and certain sorts of moral realism became separated. It will likely not surprise the reader when I suggest that the modern scientific worldview has an important place in (...) the discussion of the notion of external reasons. As mind, motivation, and perception have become less opaque to us, certain avenues for explaining our reasons have come closer to relying on hypotheses which may turn out to be falsifiable, and have thus been abandoned. What may come as more of a surprise is my suggestion that modern egalitarianism is an important factor as well. I suggest that impersonal reason has been used as an (implausible, but perhaps well-intentioned) alternative to the practice of some inflicting their reasons on others. (shrink)

We elucidate the conditions under which any hypothesis is explanatorily relevant by analyzing several tests of explanatory relevance and explanations based on those tests. A new causal criterion of explanatory relevance is developed and defended. We show how the causal criterion succeeds in establishing, at the very least, a very strong presumption against moral facts.

In this paper, I argue that an externalist theory of thought content provides the means to resolve two debates in moral philosophy. The first—that between judgement internalism and judgement externalism—concerns the question of whether there is a conceptual connection between moral judgement and motivation. The second—that between reasons internalism and reasons externalism—concerns the relationship between moral reasons and an agent's subjective motivational set. The resolutions essentially stem from the externalist claim that concepts can be grasped partially, and a new moral (...) theory, which I call ‘moral externalism’, emerges. (shrink)

Recent virtue theorists in psychology implicitly assume the truth of motivational internalism, and this assumption restricts the force and scope of the message that they venture to offer as scientists. I aim to contrive a way out of their impasse by arguing for a version of Aristotelian motivational externalism and suggesting why these psychologists should adopt it. There is a more general problem, however. Although motivational externalism has strong intuitive appeal, at least for moral realists and ‘Humeans’ about motivation, it (...) continues to be threatened by Smith’s fetishisation argument and burdened by the inability of its familiar counter-examples to internalism (of the immoral, wicked, listless and amoral persons) to bear full scrutiny. I argue that Aristotle’s example of the continent person (as distinct from the fully virtuous) offers a more persuasive counter-example to internalism. The moral judgements of continent persons do not motivate them intrinsically, yet the continent cannot be counted as practically irrational with regard to morality. If Aristotelian motivational externalism holds true, psychologists can offer full-fledged theories of virtue without the danger of turning the science of psychology into a prescriptive moralism.

Several prominent philosophers believe that moral facts are facts about what reasons we have, and that this entails that moral judgments are necessarily and inherently motivating. According to this argument, if morality cannot move us, then it is hard to understand how it could be sensibly regarded as action-guiding or normative. That is, they endorse a traditional argument for motivational judgment internalism based on moral rationalism. This paper criticizes this argument, and argues instead that there is no necessary or conceptual (...) connection between moral facts and motivation. First, I formulate MJI as the thesis that moral judgments are necessarily and inherently motivating, and introduced several refinements designed to accommodate some plausible exceptions to the initial formulation. I then introduce MR as the thesis that moral facts are identical with or analyzable in terms of facts about requirements of reason. MR is ambiguous between an interpretation that analyzes moral requirements in terms of motivating reasons, and is also subject to various possible refinements, and an interpretation that proceeds in terms of justifying reasons. Finally, I argue that neither interpretation entails any interesting or plausible formulation of MJI. If the argument of this paper are sound, then there is no important connection between moral rationalism and motivational internalism. (shrink)
