Aristotle, the son of the physician Nicomachus, was born in Stagira in 384 BC. There is very little information about the early years of his life. At the age of seventeen, he went to Athens to study at the Platonic Academy. He remained there for twenty years, from 367 to 348 BC, when Plato died. 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 youth Alexander.

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

A universal mind, Aristotle created an extensive and valuable philosophical and scientific work. Epistemology, logic, theology, physics, biology, psychology, ethics, political philosophy, and aesthetics are the main fields of knowledge that he researched and studied. The Alexandrian Hermippus estimated Aristotle's works at 400. To this day, lists have survived that include 143 titles of his works. Diogenes Laertius estimated the number of lines in Aristotle's writings at 440,000. The impact of his work on the formation of global thought was strong for centuries, and remains so.
