evidence: Plato (/ˈpleɪtoʊ/ PLAY-toe;[1] Greek: Πλάτων, Plátōn), born Aristocles (Ἀριστοκλῆς; c. 427 – 348 BC), was an ancient Greek philosopher of the Classical period who is considered a foundational thinker in Western philosophy and an innovator of the written dialogue and dialectic forms. He raised problems for what became all the major areas of both theoretical philosophy and practical philosophy, and was the founder of the Platonic Academy, a philosophical school in Athens where Plato taught the doctrines that would later become known as Platonism. [...] Plato (Greek: Πλάτων, Plátōn, from Ancient Greek: πλατύς, romanized: platys, lit. 'broad') is actually a nickname. Although it is a fact that the philosopher called himself Platon in his maturity, the origin of this name remains mysterious. Platon was a fairly common name (31 instances are known from Athens alone),[8] but the name does not occur in Plato's known family line.[9] [...] - Tarán, Leonardo (2001). "Plato's Alleged Epitaph".
