REPORT ERRORDefinition
Arcesilaus (c. 316/315 – 241/240 BCE) was a Greek philosopher, born in Pitane of Aeolis. He was the founder of the Middle Academy, the second period of the Platonic school, and is renowned for introducing skepticism into academic thought. A student of Theophrastus, Crantor, Polemon, and Crates, Arcesilaus succeeded Crates as scholarch of the Academy around 268 BCE.
Arcesilaus's philosophy was characterized by the principle of "epochē" (suspension of judgment) and "acatalepsia" (incomprehensibility). He maintained that nothing could be known with certainty, not even the certainty of uncertainty itself, and that the only correct stance was to refrain from any dogmatic assertion. This approach brought him into sharp conflict with the Stoics, particularly Zeno of Citium, whom he heavily criticized for their theories of "katalēptikē phantasia" (apprehensive impression).
Arcesilaus left no written works, and his ideas are known to us primarily through the accounts of Diogenes Laërtius, Cicero, and Sextus Empiricus. His influence was decisive for the Academy's evolution towards skepticism, shaping a tradition that would last for centuries and profoundly impact Western philosophy. His name, a compound of ἄρκος ("help, defense") and λαός ("people"), reflects his quality as a "defender of the people" or "one who provides help to the people," perhaps also in the sense of intellectual guidance.
Etymology
From the root ἀρκ- of ἄρκος derive words such as ἀρκέω ("to suffice, help"), ἄρκεσις ("help, defense"), and ἐπαρκέω ("to provide help"). From the root λα- of λαός derive words such as λαϊκός ("of the people"), λαογραφία ("description of the people"), and λατρεία ("service, worship," originally service to the people or gods). The combination of these roots creates a name with strong symbolism of protection and leadership.
