Ancient Greek philosophy
Aristotle moved to Athens in 367 BC and began to study philosophy. He studied at Plato's Academy. He left Athens twenty years later to study botany and zoology. He became a teacher of Alexander the Great and returned to Athens ten years later to create his own school: the Lyceum. At least twenty-nine of his books have survived, known as the corpus Aristotelicum. He wrote about logic, physics, optics, metaphysics, ethics, rhetoric, politics, poetry, botany, and zoology.
