Abstract
In his post-critical philosophy, Polanyi challenges the intellectual trend in modern western philosophy which exalted critical reason and denigrated the uncritical elements of knowing, such as belief, tradion and authority. In this paper, the author focuses on Polanyi’s thoughts on tradition, authority and originality in a post-critical perspective. On the one hand, Polanyi, against modern critical philosophy, fulluy acknowledges the important role played by tradition and authority in science, on the other hand, he also tries to show the tension and the deep unity between tradition, authority and originality.
