Greek philosopher and Plato's disciple Aristotle (384-322 BCE) radically altered the direction of Western philosophy. He is remembered as one of the greatest philosophers in history. The Roman statesman and philosopher Cicero once referred to his writing style as "a river of gold," and because of the breadth of his ideas and their subsequent impact on the study of science, logic, philosophical argument, and theology, many people have come to refer to him as "The Philosopher."
