Many commentators hold that in addition to the categorical imperative of morality, Kant also posits an objective law of non-moral practical rationality, 'the' Hypothetical Imperative. On this view, the appeal to the Hypothetical Imperative increases the dialectical options that Kantians have vis-a-vis Humean skepticism about the authority of reason, and it allows for a systematic explanation of the possibility of non-moral weakness of will. I argue that despite its appeal, this interpretation cannot be sustained: for Kant the only objective, universally (...) valid a priori principle of practical reason that governs transcendentally free agents is the moral law. All non-moral practical rules are mere “precepts” that lack genuine objectivity, certainty, and intersubjective validity. I suggest that for Kant the rejection of the possibility of non-moral practical laws plays an important part in his argument for the supreme rational authority of moral norms over prudential precepts of happiness.

Many of us are all too familiar with the experience of taking pleasure in things we feel we ought not, and of finding it frustratingly hard to bring our pleasures into line with our moral judgements. As a value dualist, Kant draws a sharp contrast between the two sources of practical motivation: pleasure in the agreeable and respect for the moral law. His ethics might thus seem to be an unpromising source for help in thinking about how we can bring (...) our agreeable pleasures into line with our moral values. But I argue that a careful reading of Kant’s texts reveals a helpfully realistic view about the extent to which we can modify our agreeable pleasures. On my interpretation, Kant shows us how to hold together two seemingly incompatible ideas: on the one hand, that pleasure in the agreeable is resistant to rational direction, and on the other hand, that we can cultivate these pleasures with a view to ethical self-transformation.
