In this contribution, we first discuss the aspects of the analytic method conceived by Kant in the Deutlichkeit that differentiate it from the Wolffian method and relate it to the Newtonian method. Compared to the philosophical tradition, the task of analysing concepts appears profoundly changed. Since Kant aims philosophy towards the world, he considers concepts as something given and intends to discern their characteristic marks by observing their usual applications. Although Kant abandons any attempt to define concepts nominally, he still (...) gives great relevance to words to the extent that concepts, according to him, acquire their meaning in the linguistic usage. We will also point out how for Kant the linguistic usage makes the analysis of concepts anything but easy and how a hermeneutic process is necessary for its completion. In distinguishing philosophical signs from mathematical signs, Kant provides the semiotic reasons that underlie his recourse to hermeneutics. (shrink)
