Abstract

From the very beginning of Philosophy. The Onto was just the target object of human’s thinking. Aristotle ever demonstrated that the Onto is a pure format being. (本体是纯 形式体) Then, what is this Onto? What is this pure format being? I present an answer in my this paper. If an object could exist independently, then, I call it “ZHUTI”（主体）; If a “ZHUTI” could be felt, then, I call it “SHITI”(实体), such as the stone, the tree; If a “ZHUTI” could not be felt, then, I call it “XUTI”(虚体), such as the law,the rule in the nature.“SHITI” or “XUTI” is the special being of the Onto. Refers to the Onto, its attribute is the common attribute of all the “ZHUTI”. Weknow the movement is the common attribute of all the “ZHUTI”. Then, we could say the movement is also the attribute of the Onto. From where the movement come? Besides from external, the movement come from the contradiction inside the “zhuti”, for a pair of contradiction units within a same “zhuti” could produce the force for the movement. The Onto move of course by its inside force. So, in the Onto there should be a pair of contradiction units which produce the force. Nothing could dominate the Onto. So, the pair of contradiction units in the Onto should be not another “zhuti”, but the Onto itself. This means the pair ofcontradiction units in the Onto is the Onto itself. So, the Onto is just that uniform contradiction being. It is there independently, but can not felt, so, it is “XUTI”. In the word of Aristotle, it is the pure format being（纯形式体）。The uniform contradiction being is the Onto. The Onto is the uniform contradiction being. Any “zhuti” is a kind of special uniform contradiction being body. Human, is also a kind of special uniform contradiction being body. Then, what is the uniform contradiction being body in human? This is another topic for further study. As per above answer of the Onto, we could get the way to find out what is the uniform contradiction being body in human, after we find out this answer, then, we could find out all the knowledge about the human being. These study, in fact, is already just the study ofOntology and Cognition. Here are several key words and the define in this paper: “ZHUTI” (主体) “SHITI” （实体） “XUTI” （虚体）*** “BENTI” （本体）
