An Eiementary Probe Into Arostotle's Otology Base Of Practical View

This essay aims to analyze the base of ontology in Aristotle's practice theory. And a premise is made first: Ontology is the base of Aristotle's practice theory. Then we analyzed and investigated the premise and found that the premise is true according to Aristotle's logic; on the other hand, we analyzed and investigated the relation of Aristotle's theory on ontology practice, we found because of Aristotle's argument on ontology lack of sound base that his ontology is controversial, so is his practice theory. Therefore, the whole philosophical logic of Aristotle is inconsistent. Finally, we make a comparison of Aristotle's philosophy with Marxist's on the base of argumentation to make this viewpoint clear: the Marxist philosophy, as a turning-point, plays a revolutionary role in the history of western philosophy, and the first philosophy lies not in metaphysics but in practices.
