The Autonomy of Reason: A Commentary on Kant's "Groundwork of the Metaphysic of Morals" (review)

482 HISTORY OF PHILOSOPHY with Diderot, in 1773, did not generate any excitement on either side: Diderot found the philosopher far less interesting than the patroness; Hemsterhuis, for his part, thought Diderot in person a disappointment, after reading his works. I wish I could say that I found Hemsterhuis an exciting thinker, as he is presented in Moenkemeyer 's useful and informed study. I cannot. On the other hand, this quiet philosopher from Holland stood at one of the great crossroads in the history of European thought. In his struggle against the Atheism he saw emerging from the French Enlightenment, in his stress on essences, known and unknown, as opposed to the atheistic concept of matter, in his doctrine of total personality rather than faculty psychology, in his idea of perfectibilityand the Golden Age that he likened to the afterlife--in these he had found a way out of the sterile impass confronting the disciples of Diderot and d'Holbach. In short, this is a figure of undeniable consequence historically, and he has been too long ignored by American students of philosophy. We should be grateful both to the author and to the publisher for making him known to us in this monograph, the first comprehensive study of Hemsterhuis ever published in English. WALTER E. REX University of California, Berkeley The Autonomy of Reason: A Commentary on Kant's "Groundwork of the Metaphysic of Morals." By Robert Paul Wolff. (New York: Harper & Row, 1975. Pp. x + 228. $12.50) The Autonomy of Reason reflects Wolff's determination to get out of Kant's system what is good and to get out of Kant's system for good. It thus burns with the conflicting passions of a devoted student who has learned much from a reserved teacher but who now finds it imperative to break with him for precisely the reasons that attracted him initially. This explains why much of the book reads like a declaration of independence yet is based on a sympathetic, even immanent, critique of Kant addressed to Wolff himself. Although he is addressing himself, others may share and will certainly benefit from Wolff's two decades of intense study of Kant. Without question Wolff has written a provocative and important book. Contrary to its title, however, it is not really about the autonomy of reason; and contrary to its subtitle, it is only partly a commentary on Kant's Groundwork. It serves, rather, as a propaedeutic to Wolff's own moral and political views. I believe this at least accounts for some of the puzzling features of the book: its highly personal nature, its style of philosophical commentary, and its devastating introduction. Wolff does not see his task as one of either historical exegesis or philosophical criticism. In the place of both Whiff proposes a "philosophical reconstruction" of the text. This is both desirable and necessary, he says, because "of all the great philosophers, there is none so rich in insights and so plagued by inconsistency as Kant" (p. 4). The resulting reconstruction will be worthwhile provided that affirmative answers can be given to two questions: "Does the interpretation developed here illuminate the text, so that at least some of what Kant says is clearer and more plausible in the light of it; and, more important still, does the interpretation result in an argument whose independent philosophical merit justifies the effort spent grappling with Kant?" (p. 5). A third question suggests itself: would Kant recognize himself as the author of the reconstructed text? This question one must answer in the negative, for the Groundwork that emerges, although certainly Kantian, does not accurately reflect Kantianism. To the extent that this is a criticism, it is so only because the book advertises itself as a commentary. In short, Wolff's book is similar to Strawson's Bounds of Sense in that the value of both lies in salvaging something of worth from the sunken hulk of Kantianism. Wolff's Introduction is particularly revealing, for it consists of a sustained attack on several BOOK REVIEWS 483 of Kant's central metaphysical claims, an attack which, if successful, undermines much of his ethics. As an introduction to a commentary, it prejudices the...
