Abstract
Rather than approaching Kant's moral theory in the normal way through a consideration of The Groundwork of the Metaphysics of Morals and The Critique of Practical Reason, I do so from the perspective of an extended analysis of other aspects of his work that bear on his moral philosophy . Consideration of the Doctrine of Right suggests that the universal principle of Right Kant identifies is a restricted version of the CI applied to the limited domain of relations between persons at issue in this context. Given that duties of Right deriving from this principle are also regarded as perfect ethical duties, an analysis of the nature and scope of the universal principle of Right can, I argue, be expected to be informative with respect to our understanding of perfect duties and the contradiction in conception from which these are said to derive. Allowing for the more limited scope of merely external duties of Right, analysis of these duties suggests that ethical duties of Right are obligations concerned with ensuring the capacity of rational agents to govern themselves on the basis of reason . This kind of analysis, I argue, is both confirmed and clarified by Kant's subsequent discussion of perfect and imperfect duties of virtue we owe to ourselves under the rubric of concerns with our moral health and moral prosperity. ;The resulting view is, I claim, a promising one that allows us to integrate the different treatments of duties in these two works and accommodate the various duties Kant discusses. In particular, understood in terms of the notions of moral health and prosperity, the concerns engendered here require careful consideration of the particular nature and psychology of human agency and yield a much more subtle and interesting account of duty and of the moral life than those typically associated with Kant.
