Poincare's Idea Of The Philosophy Of Science

Mainly on the base of conventionalism and intuitionism, the article carefully illuminate the Poincare's idea of philosophy of science, and expose the dialectic factor in his ideas, and put forward my own views.Chapter one: Poincare's conventionalism is a moderate conventionalism. He put emphasis on the factor of convention, but never exclude the importance of the experience. So, in a proper word, his conventionalism should be called "empirio- conventionalism". He cut the third way between the empiricism and the rationalism.Chapter two: Poincare's criticism on "the expected reason" justification for the existence of mathematical object and opposition to the postulate of real infinite provide the developmental approach for the intuitionism in philosophy of mathematics. There are some dialectical factors in the interaction between Poincare's intuition thinking and logic thinking, n the analysis of the distinct function of intuition in mathematical creation, especially in the analysis of double characteristics of mathematical reasoning.Chapter three: Taking the stand of the conventionalism and intuitionism, Poincaresummarize his own methodology of science on the base of his science work-hypothesis intuition beauty of science the choice of the scientific fact.Chapter four: Poincare give a scientific discovery and dialectic answer on the relation of the simplicity and complicity and the relation of the contingency and necessity .Chapter five: The core of the Poincare's epistemology is realism about relations. He didn't deny the reality of the entity, at the same time, he argue that the relation among the things is the more profound reality than the entity. His realism about relations is compatible to the scientific realism.
