Nowadays the human person deprives himself of his identity by complicated organization and mechanical civilization. Supposing the existentialism is to help him regain his identity that can only be realized through education. The aim of this study is to realize, through educational effort, the image of the existing person. Therefore, I examined the concept and nature of existentialism to discover the image of this individual existing person and to find an orientation, a method and teaching attitude in existential education in order to realize that image. After all, existential education focuses on authentic existence, the person himself as existing human person instead of an in Significant being losing himself in a mass society. In other words, it emphasizes the meaning of life 1) forming himself freely in the limitedness of life, 2) feeling the necessary to make a free choice in his action and to obey according to his choice, 3) being able to make a good judgement or criticism. Finally, existential education respects the human dignity, the individual character and regards the individual as a human being that cannot be substituted.
