Christian Gottlieb Selle, an empiricist critic of Kant influenced by Locke to whom Kant had sent one of the complimentary copies of the "Critique of Pure Reason", was disappointed by the work, considering it a reversion to rationalism and scholasticism, and began a polemical campaign against Kant, arguing against the possibility of all "a priori" knowledge. His writings received widespread attention and created controversy. Though Kant was unable to write a reply to Selle, he did engage in a public dispute with Feder, after learning of Feder's role in the review published in "Zugaben zu den Göttinger gelehrte Anzeigen". In 1788, Feder published "Ueber Raum und Causalität: Zur Prüfung der kantischen Philosophie", a polemic against the "Critique of Pure Reason" in which he argued that Kant employed a "dogmatic method" and was still employing the methodology of rationalist metaphysics, and that Kant's transcendental philosophy transcends the limits of possible experience. Feder believed that Kant's fundamental error was his contempt for "empirical philosophy", which explains the faculty of knowledge according to the laws of nature. With Christian Meiners, he edited a journal, the "Philosophische Bibliothek", opposed to Kantianism.
