Abstract: The discussion of free will in history is not only confined to the field of philosophy, but also permeates all aspects of human life. People have never stopped questioning this question while putting forward delicate philosophical and scientific argumentation. There are three philosophical positions on whether human beings have free will: libertarianism, hard determinism and soft determinism. Although all these claims have their own arguments, through the contextual analysis of the ideological roots of free will, it is found that whether human beings have free will is a question that has no unified answer in the case of being out of context, because the contradiction between " freedom” and " causality” is an unsolvable philosophical problem only from the ontological point of view. From the perspective of contextual identity, it seems that a reasonable explanation of " free will problem” can be given by using custom, tradition and institution as context to regulate behavior.
