Contemporary Kantians who defend Kant''s view of the superiority of the sense of duty as a form of motivation appeal to various ideas. Some say, if only implicitly, that the sense of duty is always ``available'''' to an agent, when she has a moral obligation. Some, like Barbara Herman, say that the sense of duty provides a ``nonaccidental'''' connection between an agent''s motivation and the act''s rightness. In this paper I show that the ``availability'''' and ``nonaccidentalness'''' arguments are in tension (...) with one another. And the ``availability'''' idea, although certainly supported by some passages in Kant himself, is also clearly denied in other passages. My conclusion is that Kantians will need to abandon either availability or nonaccidentalness if they wish to have a consistent set of views about the sense of duty. (shrink)

Immanuel Kant (1724–1804) argued that moral requirements are based on a standard of rationality he dubbed the “Categorical Imperative” (CI). Immorality thus involves a violation of the CI and is thereby irrational. Other philosophers, such as Locke and Hobbes, had also argued that moral requirements are based on standards of rationality. However, these standards were either desirebased instrumental principles of rationality or based on sui generis rational intuitions. Kant agreed with many of his predecessors that an analysis of practical reason (...) will reveal only the requirement that rational agents must conform to instrumental principles. Yet he argued that conformity to the CI (a non-instrumental principle) and hence to moral requirements themselves, can nevertheless be shown to be essential to rational agency. This argument was based on his striking doctrine that a rational will must be regarded as autonomous, or free in the sense of being the author of the law that binds it. The fundamental principle of morality — the CI — is none other than the law of an autonomous will. Thus, at the heart of Kant's moral philosophy is a conception of reason whose reach in practical affairs goes well beyond that of a Humean ‘slave’ to the passions. Moreover, it is the presence of this self-governing reason in each person that Kant thought offered decisive grounds for viewing each as possessed of equal worth and deserving of equal respect.
