Abstract

Paying attention to the issue of the death of authenticity and alienation of man is one of the most important issues that contemporary man is dealing with ignorning it causes that according to Heidegger; The desert is getting wider every day and the gap between self-being and alienation becomes uncontrollable. In order to understand and face this issue logically, in the present research, the meaning and why of alienation from the point of view of two prominent thinkers of the Islamic world and the West, Allameh MuhammadTaqi Ja’fari and Martin Heidegger, were discussed in a comparative manner. The research shows that for Allameh Ja’fari self-estrangement is divided into two types, positive and negative, and positive self-estrangement means placing the "self" in the path of its logical evolution, and negative self-estrangement means exclusive attention to the animal dimension and neglecting the origin and resurrection. they know and from Heidegger's point of view, losing one's understanding of one's existence and the meaning of one's world, being under the control of previous plans, becoming a passive existence, not trying and seeking to understand the meaning of existence, and also becoming a static being and passive; It takes a person out of the orbit of authenticity and true self-being and enters a space called "alienation from oneself".
