For more than two centuries, Kant scholars have operated on the unquestioned premise that Kant's three Critiques offered a systematic exposition of his philosophy. But this unitary view, argues T. K. Seung, is gravely mistaken. In Kant's Platonic Revolution in Moral and Political Philosophy, Seung shows how each of the three works represents a major reformulation of the initial commitment to Platonism which Kant had made in his Inaugural Dissertation of 1770.

For Kant, Platonic Forms are the basic ideas for constructing moral, aesthetic, and political norms and standards. This is the essence of Kant's Platonic constructivism, which Seung explicates with comparisons to other programs of construction, such as Hobbesian conventionalism and Hegelian historicism. Finally, he clarifies the link between constructivism and deconstruction.
