Arcesilaus Quotes on Knowledge

Arcesilaus (c. 316–241 BC), the founder of the skeptical phase of Plato's Academy, developed the radical version of Socratic ignorance that withholds assent (epochē) from every assertion, including the assertion that nothing can be known. Cicero and Sextus Empiricus preserve the dialectical method by which Arcesilaus argued in utramque partem against the dogmatic claims of the Stoics — especially against Zeno's "cognitive impression" as a criterion of truth — and the corresponding practical doctrine that the wise person guides action by the eulogon (the reasonable) in the absence of certainty.
