Abstract
The present paper aims to investigate the antinomic character of thinking in the philosophy of Salomon Maimon, relating it to Kantian philosophy and the Metacritics of Hamann and Herder. I will introduce the notion of the antinomy in Maimon’s philosophy first of all through his definition of “Ich” as idea and real object at once. I will then briefly explain the rise of the notion of antinomy in Maimon’s philosophy. Third, I will relate this notion to the fundamental questions quid juris and quid facti that articulate Maimon’s theory of knowledge and language. In this way, I will investigate the function of antinomic and fictional processes in his theory, stressing the productive value and critical boundaries related to the rationalization, as the comparison with Hamann’s and Herder’s Metacritics will show since it is they who identify the morphogenetic processes related to sensibility and language.
