The entirety of Plato's work ranks him among the world's foremost and most influential figures of all time, along with his teacher, Socrates, and his student, Aristotle.

Aristotle's works refer to many sciences, such as physics, biology, zoology, metaphysics, logic, ethics, poetry, theater, music, rhetoric, politics, etc., and constitute the first comprehensive system in Western Philosophy.

Perhaps the greatest of the Greek philosophers. Although he left no writings, he forever changed how we understand philosophy and influenced almost all other schools of philosophy.
