Aristotle’s career divides itself naturally into three periods: the twenty (some say nineteen) years at Plato’s Academy, from 368 to 348; the thirteen years of travel, from 348 to 335; and the return to Athens, or the years in the Lyceum, from 335 to 323.
When young Aristotle arrived at the Academy, Plato was away on a second journey to Syracuse. When the master returned the following year, however, Aristotle became his prize student and ardent friend. Although most of Aristotle’s earlier works have been preserved only in fragments, usually in quotations within works by later scholars of the Peripatetic School,several are attributed to this period and the one that followed.
As Plato’s method was dialogue, Aristotle, like other students at the Academy, began writing in dialogue.Aristotle was influenced by Plato about the time the master altered his own form, moving toward dialogues other than those with Socrates as questioner and main speaker. Aristotle, in turn, made himself the main speaker in his own dialogues.
Some scholars consider De anima the best of Aristotle’s works from this period. Translated as On the Soul, this work treats the soul and immortality, and it is imitative of Plato’s Phaedn,which was written c. 388-366 b.c.e. (Critic Werner Jaeger believes that each of Aristotle’s early dialogues was influenced by a particular Platonic dialogue, that the student was still dependent on the master as far as metaphysics was concerned but independent in the areas of methodology and logic.) Aristotle’s Protrepticus (Protreptics) is named for a term designating a letter written in defense of philosophy; the method employed in this work (questions and answers by teacher and student) is from Plato, but the protreptic form is borrowed from the philosopher Isocrates, who was also at Athens during this time. In the year 348 (or 347), two events influenced Aristotle’s future: the death of Plato (and possibly the choice of a new leader of the Academy), which caused Aristotle to leave Athens, and Philip II’s destruction of Stagirus, which caused the philosopher to look elsewhere for a new home.
With a fellow Academic, Xenocrates,Aristotle left Athens for Mysia (modern Turkey), accepting the invitation of Hermeias, a former fellow student at the Academy who had risen from slavery to become ruler of Atarneus and Assos. Aristotle presided over his host’s small Platonic circle, making of it a school modeled after the Academy. He married Pythias, niece and adopted daughter of Hermeias, after the ruler’s death; they had a daughter, also named Pythias. His wife lived until late in Aristotle’s so-called second Athenian period. After three years came another move, this time to Mytilene, on the nearby island of Lesbos; it is possible that Theophrastus found him a suitable place of residence there. Having begun research in marine biology at Assos, Aristotle continued this work at Mytilene. During these years, he probably wroteDe philosophia (On Philosophy), Ethica Eudemia (Eudemian Ethics), and early portions of Physica (Physics), Metaphysica (Metaphysics),...
