This book presents a comprehensive analysis of Kant's justification of the categorical
imperative. The book contests the standard interpretation of Kant's views by arguing that he
never abandoned his view about this as expressed in his Groundwork. It is distinctive in the
way in which it places Kant's argument in the context of his transcendental philosophy as a
whole which is essential to understand it as an argument from within human agential
self-understanding. The book reviews that existing literature then presents a logical
construction of Kant's argument which it defends by examining what Kant has to say about
synthetic a priori practical propositions in the context of his transcendental philosophy as a
whole and by a detailed examination of how he presents his argument in the Second Critique and
the Groundwork. Particular attention is given to the views of two scholars who share many of
the views expressed in this book: Klaus Steigleder and Michael Wolff. Special attention is also
given to the views of Owen Ware who while sharing many of our arguments has a very different
overall view. The concluding chapter provides a statement about the validity of Kant's
argument.
