What makes Aristotle's philosophy alive today? Concise and practical, it brings us down from the heavens to the earth, explains the structure of the world, and teaches us to think clearly. Aristotle's philosophy is often called the foundation of European thought, and behind this formulation lies a remarkable simplicity: the philosopher speaks about the world in a way that allows his words to be lived and tested through experience.
