Skepticism

The stance that certain knowledge may be out of reach — and that the honest, even tranquil, response is to suspend judgment.

Greek skepticism is the tradition of systematic doubt about whether certain knowledge is possible at all. It ran in two streams. The Academic skeptics (Arcesilaus and Carneades, 3rd–2nd c. BCE) turned Plato's Academy toward arguing against dogmatic certainty. The Pyrrhonists, who traced themselves to Pyrrho of Elis (c. 360–270 BCE) and were revived by Aenesidemus, sought suspension of judgment (epoche) as a road to tranquility (ataraxia). Preserved largely through Sextus Empiricus (c. 200 CE), these arguments were rediscovered in the Renaissance and went on to shape Montaigne, Descartes, and the whole modern problem of knowledge.
