Abstract

Kant's account of “precepts of prudence” raises a striking interpretive puzzle. On the one hand, he presents such precepts as normative-practical rules; on the other hand, he relegates them to theoretical philosophy. I argue that to render these two strands coherent, we must assume that our empirical nature is a source of normativity for us: prudence is normative for us just because we have an “unconditional” empirical desire for obtaining happiness, a maximum of pleasant sensations. Since rules of prudence cognize the means for causing a state of affairs that we desire and value insofar as we are receptive natural beings, these rules do not presuppose the active self-legislation of practical reason. Hence they belong to the theoretical cognition of nature.
