Ancient Greek Philosophy is not just about thinking and ideas. The definition of philosophy used to encompass ethics, politics, metaphysics (both spiritual and physical medicine), rhetoric, and other modalities.
Plato and Aristotle are two of the most reputable figures of Western philosophy. Aristotle was Plato’s student at the Academy in Athens. However, some say Aristotle ended up surpassing his teacher.
