My bad, yesterday i made a mistake, Plato taught Aristotle as well as he did Socrates......

Aristotle's epistemology

Plato (left) and Aristotle (right), a detail of The School of Athens, a fresco by Raphael. Aristotle gestures to the earth, representing his belief in knowledge through empirical observation and experience, while holding a copy of his Nicomachean Ethics in his hand, whilst Plato gestures to the heavens, representing his belief in The Forms, while holding a copy ofTimaeus

"Aristotle" by Francesco Hayez (1791–1882)

Like his teacher Plato, Aristotle's philosophy aims at the universal. Aristotle's ontology, however, finds the universal in particular things, which he calls the essence of things, while in Plato's ontology, the universal exists apart from particular things, and is related to them as their prototype or exemplar. For Aristotle, therefore, epistemology is based on the study of particular phenomena and rises to the knowledge of essences, while for Plato epistemology begins with knowledge of universal Forms (or ideas) and descends to knowledge of particular imitations of these. For Aristotle, "form" still refers to the unconditional basis of phenomena but is "instantiated" in a particular substance (seeUniversals and particulars, below). In a certain sense, Aristotle's method is both inductive and deductive, while Plato's is essentially deductive from a priori principles.[2
