This classic of Kant scholarship, whose first edition appeared in 1932, deals with one of the most controversial and difficult topics in the Critique of Pure Reason: Kant's table of judgments and their connection to the table of categories. Kant's attempt to derive the latter from the former is called the "Metaphysical Deduction," and it paves the way for the Transcendental Deduction that is universally recognized as the heart of the Critique. Many commentators have passed over the Metaphysical Deduction in silence, as if embarrassed by Kant's fatuity, and his critics are almost unanimous in finding its premise ungrounded, its argument incorrect, and its conclusion false. At the heart of the failure of the Metaphysical Deduction, it is alleged, is Kant's inability to justify the table of the forms of judgment. Critics argue that Kant simply took these forms of judgment from the logic textbooks of his day and doctored them so as to yield the required categories. Such objections were current even in Kant's time; they were repeated by Hegel, and are commonplaces of Kant criticism today. This book is the fullest and most systematic evaluation ever made of the Metaphysical Deduction. Reich argues that its principal conclusion is correct even though Kant failed to establish it in the Metaphysical Deduction proper, and he defends the conclusion by using Kant material far removed from the text of the Metaphysical Deduction, notes by Kant that only became available in the 1920's and that remain even now untranslated into English. With the publication of this translation for English-speaking Kant scholars, a neglected and impugned part of the Critique of Pure Reason can finally receive the attention it deserves.
