The fact that Hegel did not join the Kantian reading group at the Tübingen Stift, in 1790, is generally seen as proof that he was not interested in the first Critique. However, early references to Kant, from 1787, in the passages Hegel recopied from primary and secondary sources, show that he had already adopted elements essential to the development of his own thought. These elements were in contradiction whith the theoretical tendencies of thegroup, led by the « Kantianer enragé » Carl Diez. These ideas ran counter to the notion of speculative language which Hegel was beginning to develop, based on Kant’s antinomies of pure reason.
