In this article I argue against the very diffused interpretation according to the year of 1769 represented a frontier in the formation of transcendental philosophy and that the Dissertation of 1770 corresponds to the first critical text. The objective of this article is to investigate the origin of the antinomies in Reflections in the seventies. It doesn't mean to sketch the antinomies, so about them Kant is reticent in this period. They are object of his attention only the day before writing the Critique of pure reason. I deal with a few elements that will make possible their formulation and solution in Critique fo pure reason.
transcendental analytic; transcendental dialetic; reason; understanding; antinomy
