The Questioning And Thinking About The Origin Of The Hypothesis Prerequisites Of "Synthetic A Priori Judgement" Of Kant's

Kant thought that man's ability of intuition is priori to the objection which be intuited, which decide what he can intuit. And what he has intuited be judged by the conception which he has , and then become into knowledge. Man's ability of intuition and the conception which he has are priori and independent of target which is not from himself. The technical term which be used to express such knowledge by Kant is : synthetic a priori judgement .the hypothesis"synthetic a priori judgement"of Kant's is build on two prerequisites: one is structure of the a priori knowledge ; the other is synthetic a priori ability . He thought man's structure of the a priori knowledge is absolutely independent of all experience. And it is possible for structure of the a priori knowledge to being ,because we have synthetic a priori ability which is according to our structure of the a priori knowledge. Which leave us two questions: one is where is our structure of the a priori knowledge from? The other is where is our synthetic a priori ability from? And the two questions on balance is to question the same question: the question of origin, it is where are structure of the a priori knowledge and synthetic a priori ability from? It can be figure out when we find the origin. But where we can find the origin on earth? In another word, where is the"road"through which we can find the origin ? By researching Piaget's microscopic investigating about origin of knowledge, this thesis is to read and seek structure of the a priori knowledge and synthetic a priori ability'origin of Kant's throughout The Principles Of Genetic Epistemology of Piaget's, and come into deeper think by comparing Kant's and Piaget's, studying Piaget's philosophy question.
