Aristotle (384 BCE - March 7, 322 BCE) was an ancient Greek philosopher, a student of Plato and teacher of Alexander the Great. He wrote on diverse subjects, including physics, poetry, biology and zoology, logic, rhetoric, politics and government, and ethics. Along with Socrates and Plato, Aristotle was one of the most influential of ancient Greek philosophers. They transformed Presocratic Greek philosophy into the foundations of Western philosophy as we know it. Some consider Plato and Aristotle to have founded two of the most important schools of Ancient philosophy; others consider Aristotelianism as a development and concretization of Plato's insights.
