Bolzano vs. Kant. O case study das categorias

Bolzano was a fierce opponent of Kant’s philosophy, but he does not devote much space to the thematic critique of the concept of category, even though it is a crucial question for the transcendental philosophy. My aim is to present Bolzano’s punctual criticisms to the Aristotelian category and to the Kantian table, and to delineate some peculiar concepts of Bolzano, based on which the notion of summum genus is originally rethought and any deduction is radically rejected.
