During the subsequent Hellenistic period, philosophical schools began to appear which had a greater focus on epistemological questions, often in the form of philosophical skepticism. For instance, the Pyrrhonian skepticism of Pyrrho and Sextus Empiricus held that eudaimonia (flourishing, happiness, or "the good life") could be attained through the application of epoché (suspension of judgment) regarding all non-evident matters. Pyrrhonism was particularly concerned with undermining the epistemological dogmas of Stoicism and Epicureanism. The other major school of Hellenistic skepticism was Academic skepticism, most notably defended by Carneades and Arcesilaus, which predominated in the Platonic Academy for almost two centuries.
