According to the standard view, Kant held that hypothetical imperatives are universally binding edicts with disjunctive objects: take-the-means-or-don't-have-the-end. But Kant thought otherwise. He held that they are edicts binding only on some - those who have an end.

Kant holds that the applicability of the moral ‘ought’ depends on a kind of agent-causal freedom that is incompatible with the deterministic structure of phenomenal nature. I argue that Kant understands this determinism to threaten not just morality but the very possibility of our status as rational beings. Rational beings exemplify “cognitive control” in all of their actions, including not just rational willing and the formation of doxastic attitudes, but also more basic cognitive acts such as judging, conceptualizing, and synthesizing.

In his early writings, Kant says that the solution to the puzzle of how morality can serve as a motivating force in human life is nothing less than the “philosophers’ stone.” In this dissertation I show that for years Kant searched for the philosophers’ stone in the concept of “respect” (Achtung), which he understood as the complex effect practical reason has on feeling. -/- I sketch the history of that search in Chapters 1-2. In Chapter 3 I show that Kant’s (...) analysis in Groundwork I is incomplete because it does not explain how respect functions as a feeling in motivating choice. In Chapter 4 I argue that Kant’s subsequent attempt to sidestep this explanation in Groundwork III is unsuccessful, and that his position remains open to a skeptical threat. The argument in the second Critique, which I reconstruct in Chapters 5-6, overcomes this threat, and in doing so explains how the feeling of respect is both painful and pleasurable. -/- In the course of defending these claims, I provide an alternative reading of the shift in Kant’s ethical project from the Groundwork of 1785 to the second Critique of 1788 Against a common view in the literature, I argue that the shift does not concern the direction of Kant’s deduction (from freedom to morality, or morality to freedom); rather, it concerns his view of human sensibility and the resources he thinks we have to make our practical self-understanding intelligible. In the second Critique, I argue, Kant develops a novel approach to moral feeling from the perspective of the human agent; and this in turn clears room in his ethics for a new kind of a priori knowledge—namely, knowledge of what the activity of practical reason must feel like. By way of conclusion, I offer a few reasons for why the form of Kant’s argument in the second Critique is still relevant today, as it shows why we can only address moral skepticism from a first-personal perspective.
