Answer: I would contend that the right answer is Plato.
Explanation: Just to elaborate a little on the answer, it can be added that Athenian philosopher Plato (428/427-348/347 BCE) was his most famous and devoted student, and the one who, together with Aristotle—who was in turn Plato's student—helped preserve and spread out his important teachings. Some of Plato's most original ideas are the so-called theory of Forms, which claims that the world that we know through our senses is only an imitation of the eternal and unchanging world of the Forms, as well as the idea of the "Platonic love," as opposed to romantic love, which departs from carnal attraction in search of beauty and truth.
