Aristotle, son of the physician Nicomachus, was born in Stagira in 384 B.C. Information about his early years is minimal. At the age of seventeen, he went to Athens to study at the Platonic Academy. He stayed there for twenty years, from 367 to 348 B.C., until Plato's death. Then Aristotle left for Assos in Troad, and after a three-year stay there, he went to Lesbos and then to Macedonia, where he took on the education of the royal child Alexander.

When his student ascended the throne, Aristotle settled in Athens and founded his school, the Lyceum. After Alexander's death (323 B.C.), the philosopher's stay in Athens became difficult. He was forced to seek refuge in Chalcis, his mother's homeland, where he died in 322.

As a universal spirit, Aristotle created a vast and valuable body of philosophical and scientific work. Epistemology, logic, theology, physics, biology, psychology, ethics, political philosophy, aesthetics are the main fields of knowledge that he explored and studied. The Alexandrian Hermippus estimated Aristotle's works to be 400. To this day, lists containing 143 titles of his works have survived. Diogenes Laertius estimated the number of lines of Aristotelian writings to be 440,000. The influence of his work on the formation of world thought was, for centuries, and remains, strong.
