This chapter summarizes the major findings of the book. It emphasizes once more the importance of a historically as well as philosophically well-informed assessment of Kant’s theory of logic. It then draws out two basic takeaways of the study. One is that there is still much more to explore about Kant’s logic. The other is that we can now reconsider Kant’s place in the history of logic, in terms of the impact of his theory of logic as well as its relation to previous theories. Contrary to standard portrayers, this book proposes that the most profound and deserving legacy of Kant’s theory of logic is his endeavor to overhaul the relation between logic proper, in whichever formal-logical system it may be exemplified, and such other sciences as metaphysics and psychology.
