Answer 3

"It was Plato who formulated most of philosophy’s basic questions—and doubts. It was Aristotle who laid the foundation for most of the answers. Thereafter, the record of their duel is the record of man’s long struggle to deny and surrender or to uphold and assert the validity of his particular mode of consciousness."

Review of J.H. Randall’s Aristotle,

The Objectivist Newsletter, May 1963

When you consider that Aristotle "laid the foundation," how do you compare any other man's accomplishments to his? I terms of philosophy in the battle for men's minds, it is like the battle for men's souls when people speak of God and Satan. Except that man's mind IS the seat of his soul, in the form of his conscience. We use the ideas of Plato and Aristotle in everything little minute thing we do. Aristotle discovered the rules of logic by which every human thinks, by which every debate is won, by which parents teach their children. So who is more powerful than Aristotle, without forgetting that Aristotle is still a huge part of Christian doctrine (through Thomas Aquinas.) Aristotle and Aquinas changed the face of Christianity forever; but so did Plato, when Augustine incorporated HIM in to Christianity, resulting indirectly in the Dark Ages.

Such power those two men had! Their ideas still rule the Western world, and Aristotle has a large part to play in the Arab world, as well, because they had Aristotle's writings in their possession, translated him first, used those parts of him that fit for them into their world, and it was from the Arabs that Aquinas acquired those writings, along with much of the Arab translations.

"Aristotle is the champion of this world, the champion of nature, as against the supernaturalism of Plato. Denying Plato’s World of Forms, Aristotle maintains that there is only one reality: the world of particulars in which we live, the world men perceive by means of their physical senses. Universals, he holds, are merely aspects of existing entities, isolated in thought by a process of selective attention; they have no existence apart from particulars. Reality is comprised, not of Platonic abstractions, but of concrete, individual entities, each with a definite nature, each obeying the laws inherent in its nature. Aristotle’s universe is the universe of science. The physical world, in his view, is not a shadowy projection controlled by a divine dimension, but an autonomous, self-sufficient realm. It is an orderly, intelligible, natural realm, open to the mind of man."

Leonard Peikoff, The Ominous Parallels

"Aristotle’s philosophy was the intellect’s Declaration of Independence. Aristotle, the father of logic, should be given the title of the world’s first intellectual, in the purest and noblest sense of that word. No matter what remnants of Platonism did exist in Aristotle’s system, his incomparable achievement lay in the fact that he defined the basic principles of a rational view of existence and of man’s consciousness: that there is only one reality, the one which man perceives—that it exists as an objective absolute (which means: independently of the consciousness, the wishes or the feelings of any perceiver)—that the task of man’s consciousness is to perceive, not to create, reality—that abstractions are man’s method of integrating his sensory material—that man’s mind is his only tool of knowledge—that A is A."

“For the New Intellectual,” from the book For the New Intellectual: Ayn Rand

You won't find that kind of testimony for Plato or for any modern man.
