Plato & Aristotle

Aristotle (384 - 322 BCE)

Born at Stagira in northern Greece, Aristotle was the most notable product of the educational program devised by Plato; he spent twenty years of his life studying at the Academy. When Plato died, Aristotle returned to his native Macedonia, where he is supposed to have participated in the education of Philip's son, Alexander (the Great). He came back to Athens with Alexander's approval in 335 and established his own school at the Lyceum, spending most of the rest of his life engaged there in research, teaching, and writing. His students acquired the name "peripatetics" from the master's habit of strolling about as he taught. 

Aristotelic knowledge : 

Sensation is the passive capacity for the soul to be changed through the contact of the associated body with external objects. 

Thought is the more active process of engaging in the manipulation of forms without any contact with external objects at all. 

Desire is the origin of movement toward some goal. 

Plato (427—347 BCE)

Plato is one of the world’s best known and most widely read and studied philosophers. He was the student of Socrates and the teacher ofAristotle, and he wrote in the middle of the fourth century B.C.E. in ancient Greece. Though influenced primarily by Socrates, to the extent that Socrates is usually the main character in many of Plato’s writings, he was also influenced by Heraclitus, Parmenides, and the Pythagoreans. 

Platonic epistemology holds that knowledge is innate, so that learning is the development of ideas buried deep in the soul, often under the midwife-like guidance of an interrogator. Plato believed that each soul existed before birth with "The Form of the Good" and a perfect knowledge of everything. Thus, when something is "learned" it is actually just "recalled."
