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.

According to a common interpretation, most explicitly defended by Onora O’Neill and Patricia Kitcher, Kant held that epistemic obligations normatively depend on moral obligations. That is, were a rational agent not bound by any moral obligation, then she would not be bound by any epistemic obligation either. By contrast, in this paper, I argue that, according to Kant, some epistemic obligations are normatively independent from moral obligations, and are indeed normatively absolute. This view, which I call epistemicism, has two parts. (...) First, it claims that in the absence of other kinds of obligations, rational agents would still be bound by these epistemic obligations, i.e., that the latter are normatively independent. Second, it claims that, no matter what other obligations are at stake, rational agents are bound by these epistemic obligations, i.e., the normativity of these epistemic obligations is absolute in that it cannot be undercut by any moral or other sort of obligation. The argument turns on an exploratory reading of Kant’s remarks in “What Is Orientation in Thinking?” (1786) about the maxim of “thinking for oneself” as the “supreme touchstone of truth.” In contrast to O’Neill and Kitcher, I argue that if we interpret this maxim as stating the unifying principle of theoretical and practical reason, then we must interpret it as stating an epistemic, and not merely practical imperative. This result, I argue, vindicates epistemicism and illuminates interesting lessons about Kant’s conception of the category of “epistemic” norms. Further, it helps us make headway with Kant’s enigmatic remarks about the unity of practical and theoretical reason in the Groundwork, first and the second Critiques, and the Lectures on Logic. On my proposal, principles of the practical and theoretical uses of rea-son are unified through a formal epistemic principle. (shrink)
