Aristotle, the father of Western philosophy

Aristotle was a philosopher and scientist from ancient Greece. He was born in Stagira, an ancient Greek colony in Thrace, in 384 BC, and alongside Plato and Socrates, is considered the father of Western philosophy.
His philosophy was based on the research of Plato, his teacher, for an eternal and unchangeable principle that would explain the way in which changes in nature take place.
Over the course of his life he also devoted himself to the study of Greek tragedy: his first reflections on the subject are covered in Poetics, a work containing the fundamental elements for understanding tragic theatre.
