Aristotle (384-322 B.C.) was Plato's student, but revised his teacher's ideas to be more consistent with ordinary experience. He thought human beings are one with the rest of nature, yet set apart from it by their ability to reason. Aristotle systematized the laws of thought, gave a complete account of nature and God, and developed an attractive view of the good life and the good society. He also provided the first systematic expositions of physics, biology, psychology, and the standards of literature.
