What's Wrong with Moral Internalism

Moral Internalism is the claim that it is a priori that moral beliefs are reasons for action. At least three conceptions of ‘reason’ may be disambiguated: psychological, epistemological, and purely ethical. The first two conceptions of Internalism are false on conceptual, and indeed empirical, grounds. On a purely ethical conception of ‘reasons’, the claim is true but is an Externalist claim. Positive arguments for Internalism — from phenomenology, connection and oddness — are found wanting. Three possible responses to the stock Externalist objections are uncovered and overturned. In so doing a close relation between Internalism and Behaviourism is revealed, and some stock anti‐behaviouristic arguments are co‐opted for Externalism. The likely dependence of Internalism on an Atomistic Associationism is uncovered and criticised. Internalism is seen as being ultimately a type of Ethical Determinism. Finally, a sketch of an Anti‐Associative Externalism is given whereby the notion of self determination of action is put forward as an account of moral motivation fit to resist both the internalist and the belief‐desire psychology premises of the stock non‐cognitivist argument.
