Aristotle - 384—322 , Greek philosopher, b. Stagira. He is sometimes called the Stagirite.
Aristotle’s father, Nicomachus, was a noted physician. Aristotle studied (367—347 ) under Plato at the Academy and there wrote many dialogues that were praised for their eloquence. Only fragments of these dialogues are extant.
He tutored (342—c.339 ) Alexander the Great at the Macedonian court, left to live in Stagira, and then returned to Athens. In 335 he opened a school in the Lyceum; some distinguished members of the Academy followed him. His practice of lecturing in the Lyceum’s portico, or covered walking place (peripatos), gave his school the name Peripatetic. During the anti-Macedonian agitation after Alexander’s death, Aristotle fled in 323 to Chalcis, where he died.
Aristotle’s extant writings consist largely of his written versions of his lectures; some passages appear to be interpolations of notes made by his students; the texts were edited and given their present form by Andronicus of Rhodes in the 1st cent. Chief among them are the Organum, consisting of six treatises on logic; Physics; Metaphysics; De Anima [on the soul]; Nicomachean Ethics and Eudemian Ethics; De Poetica [poetics]; Rhetoric; and a series of works on biology and physics. In the late 19th cent. his Constitution of Athens, an account of Athenian government, was found.
