The form of practical knowledge : a study of the categorical imperative /

This important, densely argued book by Engstrom (Univ. of Pittsburgh) repays careful reading. The first half derives Kant's categorical imperative from the conditions of practical knowledge, whereby Kant's concepts of desire, intention, wish, choice, and practical judgment are rigorously distinguished. These foundational concepts are rarely explained so thoroughly, and are essential to understanding Kant's philosophy and his ethics in particular. On this foundation, the second half argues for the full equivalence of Kant's many formulations of the categorical imperative. In particular, it argues that Kant's "formulation of universal law" can derive not only "perfect" but also "imperfect duties," and not only duties to others but also duties to oneself. This is an important rejoinder to much recent scholarship (e.g., Allen Wood's Kantian Ethics, CH, Aug'08, 45-6705) that denies the equivalence of Kant's formulations. This book will be very difficult for undergraduates, but is necessary reading for graduate students and faculty who study Kant's ethics or teach Kant's Groundwork of the Metaphysics of Morals.
