Carneades

Carneades krn??d?z [key], 213?129 BC, Greek philosopher, b. Cyrene. He studied at Athens under Diogenes the Stoic, but reacted against Stoicism and joined the Academy, where he taught a skepticism similar to that of Arcesilaus. He denied the possibility of absolute certainty in knowledge; it is disputed whether he held that probable knowledge was adequate to guide a person's actions. He recognized three degrees of probability, and his teaching anticipated modern discussions of the nature of empirical knowledge.
