Kant's Early Critics: The Empiricist Critique of the Theoretical Philosophy (review)

Brigitte Sassen has translated and edited an extremely useful collection of texts dating from the years 1782 to 1789. Most of the texts were written by Kant's empirically minded critics, but a few are the work of defenders of the Critical philosophy. Although some have been translated before—e.g., the notorious Feder/Garve review of the first Critique that prompted Kant's vitriolic response in the Prolegomena, the original Garve review that served as the basis of the Feder/Garve review, and Jacobi's critique of Kant's transcendental idealism—the entire anthology is the first ever to be devoted exclusively to English translations of some of the first reactions to and defenses of Kant's theoretical philosophy. All of this makes for an exciting event in Kant studies.

Sassen identifies three major trends in Kant criticism that began in 1782. The first is the empiricist reaction to Kant's theoretical writings. Sassen considers the year 1789 the endpoint of this trend, since critical attention, she argues, shifted around that time to the rationalist reaction to Kant's writings. The initial wave of rationalist criticism, which constitutes the second trend, lasted until 1793. The third and final trend, she says, is the more forward-looking one that eventually blossomed into the systems of post-Kantian thought.

Given such a wealth of material, Sassen has focused on Kant's empiricist critics, choosing the writers and topics most representative of the overall empiricist critique of the 1780s. The selections are divided into five sections. The first consists of the Feder/Garve and Garve reviews (from 1782 and 1783, respectively). Since these were the very first reviews of the Critique of Pure Reason, they helped to formulate many of the classic objections to it. For example, not only does the standard charge of Berkeleyan idealism originate in these reviews, but Feder and Garve also express concerns about Kant's ability to distinguish between reality and illusion if nothing in sensation itself determines the understanding to combine sensations in one way as opposed to another. The second section contains discussions of the Transcendental Aesthetic, including an early version of the "neglected alternative" charge more famously made by Trendelenburg in the nineteenth century. Hermann Andreas Pistorius, one of the most sophisticated of Kant's empiricist critics, argues that Kant has not ruled out the possibility that space and time are both forms of sensibility and properties of things in themselves. The third section (especially Jacobi's famous critique) explores the relationship between appearances and things in themselves, the problem of affection, and other topics touching on the very nature of Kant's idealism. The fourth section deals with various issues involving the table of categories. For example, Kant's critics had doubts about its completeness, and they were also puzzled as to how a priori concepts could be applied to ordinary experience. The fifth and final section looks at the contrast between empiricism and purism, that is, the overall adequacy of empiricist and Kantian approaches to issues in metaphysics and epistemology. Here we find Pistorius once again writing thoughtfully about the Critical philosophy, this time in response to Carl Christian Erhard Schmid, the author of a dictionary for the "easier use" of Kant's writings that went through several editions in the late 1780s and 1790s.

This brief sketch of Sassen's book gives only an inadequate idea of its richness and usefulness. Her introduction, which is thorough and informative, patiently sorts out the various players in the debates of the 1780s, outlines their arguments with Kant and one another, and even describes the nature of periodical publication in late eighteenth-century Germany. The editorial apparatus includes short biographies of the participants in the debates as well as the other authors mentioned throughout the book...
