The relationship between tradition and modernity is one of the subjects that dealing with it, in all fields of knowledge of the modern age and also in the methods of confrontation of the western culture and civilization with other cultures and civilizations, is inevitable. In this article after giving the definitions of tradition, Modernism, post-Modernism and characteristics of traditionalist, modernists, and post- modernists, based on the view of the great thinker martyr and the effect of its holism over other sectors have been the principal cause of challenge between the tradition and modernity in the western civilization. From his point of view this challenge cannot be seen in every culture and civilization. In the western world some events led to the perception of the universe and the human being. The way out of this challenge is to separate the sacred and unscarred parts of the tradition and paying attention to different parameters of mankind entity.Tradition in its specific sense forms a solid foundation for every culture and civilization.Furthermore, it has been pointed out that the post-modernist human, although has criticized most principal thoughts of the modernists, but because of his negligence in dealing with the causes of the crisis facing modernists, has been misled and trapped in scepticism and relativism and deprived from the peace resulting from the real science and the strong foundations of the tradition.
