The aim of this paper is to show the unity and consistency of Kant’s reflections throughout all three sections of the Canon of Pure Reason. More specifically, I argue that Section 3, which is devoted to the issue of Fürwahrhalten, or taking-to-be-true, is crucial to achieving the methodological goal of the Canon, which is to justify the legitimacy of the speculative assumptions of pure reason. After examining the historical roots of Kant’s notion of a transcendental doctrine of method, I focus (...) on the methodological role that the practical element plays in the first two sections of the Canon. I then show how the limitations of Kant’s argument necessitate the introduction of a third crucial section, which serves both an analytic and an orientative function. (shrink)

What is the highest good actually good for in Kant’s third Critique? While there are well-worked out answers to this question in the literature that focus on the highest good’s practical importance, this paper argues that there is an important function for the highest good that has to do exclusively with contemplation. This important function becomes clear once one notices that coherent [konsequent] thinking, for Kant, was synonymous with "bündiges" thinking, and that both are connected with the highest good in (...) the third Critique’s moral proof for God’s existence. I show that the original meaning of "bündig," which is from the carpentry trade and has been forgotten, illuminates the stakes of the highest good in Kant’s system. For us, as proverbial carpenters of reason, coherence is essential for the intellectual activity of constructing a philosophical worldview in his transcendental idealism. I motivate the reading further by showing how this function can neatly reconstruct Kant’s proof for God’s existence in the third Critique. I conclude by sketching Kant’s reasons for why the project of creating a coherent worldview grounded in the highest good is worth the labor costs. (shrink)
