Kant was not satisfied with the review. He took the charge that he is an idealist like Hume and Berkeley (which is Garve’s key charge against him) very seriously. He complained that Garve had not understood him, and decided to write a response, which came in the form of a new book, Prolegomena to Any Future Metaphysics (1783). In the Prolegomena, Kant summarizes and explains the key arguments of the Critique. In the book’s appendix he offers his rebuttal of Garve’s review.
In August 1783, a journal published a short piece on the Prolegomena and called special attention to Kant’s charge that Garve had not understood him. Garve responded with an article in which he said: “If the honorable and witty man [Kant] did not live so much in the clouds, if he did not use a terminology of his own and if his sentences were shorter and simpler, he might be less exposed to this danger [of being misunderstood].” Later on the original version of Garve’s review of the Critique was published in another journal, but Kant was still dissatisfied with it.
