Abstract

In Filosofia dell’Espressione Giorgio Colli theoretically justifies what in La sapienza greca and lessons in Parmenides, Gorges, and Zeno confront philologically. This study retraces Colli’s critique of Aristotelian qualitative logic. Through the analysis of the representation, the object (cogitatio or extensio) is brought back to the partitive matrix of modal logic (necessary or contingent). The sphere of the contingent returns the object to the ante-predicative dimension and leads the constructive reason to what Colli calls a «checkmate».
