ARISTOTLE
An ancient Greek philosopher who lived 384-322 BCE, one of only two philosophers from that period whose works are still extensively studied today, the other being his teacher, Plato (427?-347 BCE). In fact, throughout the twentieth century and into the twenty-first, Aristotle’s ideas, especially in the realm of political philosophy, predominated. He was born in Stagira, Ionia, so is sometimes referred to as “the Stagirite.” His father, Nicomachus, a court physician to Amyntas II, king of Macedon, died when he was just a boy; he was raised by a guardian, Proxenus, who sent him to Plato’s Academy in Athens when he was seventeen. After his studentship, he joined the faculty of the Academy and taught there until Plato’s death. When Plato’s nephew, Speusippus, succeeded as head of the Academy, Aristotle and several others left. During the next few years, he made zoological investigations in various places in the Grecian world.
