The Complete Works of Aristotle (PDF)

Ancient Greek philosopher Aristotle, together with Socrates and Plato, laid much of the groundwork for western philosophy.
Who Was Aristotle?
Aristotle (c. 384 B.C. to 322 B.C.) was an Ancient Greek philosopher and scientist who is still considered one of the greatest thinkers in politics, psychology and ethics. When Aristotle turned 17, he enrolled in Plato’s Academy. In 338, he began tutoring Alexander the Great. In 335, Aristotle founded his own school, the Lyceum, in Athens, where he spent most of the rest of his life studying, teaching and writing. Some of his most notable works include Nichomachean Ethics, Politics, Metaphysics, Poetics and Prior Analytics.

Aristotle’s Books
Aristotle wrote an estimated 200 works, most in the form of notes and manuscript drafts touching on reasoning, rhetoric, politics, ethics, science and psychology. They consist of dialogues, records of scientific observations and systematic works. His student Theophrastus reportedly looked after Aristotle’s writings and later passed them to his own student Neleus, who stored them in a vault to protect them from moisture until they were taken to Rome and used by scholars there. Of Aristotle’s estimated 200 works, only 31 are still in circulation. Most date to Aristotle’s time at the Lyceum.
