Non si dimostra il vero: la critica di Sesto Empirico ai procedimenti apodittici

Thanks to a careful reading of a key passage in Sextus Empiricus’s Outlines of Pyrrhonism (PH II 134-170), this paper offers a sort of running commentary that makes clear some crucial aspects of the Pyrrhonian attack against any kind of subsistence or ὑπόστασις of the ἀπόδειξις. This notion (fundamental for the dogmatic approach to epistemological topics) will be examined in its main logical guidelines as well as in some of its historical declinations, especially from the point of view of ancient Stoicism and its doctrine about the so-called non-demonstrable arguments
