To know the nature of thought and philosophy in Heidegger’s view, in the present article we have firstly distinguished between thought and philosophy. The subject of philosophy is existent and the subject of thought is existence. Unlike the existent, existence is not something presupposed and imagined. The thought is reminding the existence. Existence escapes from us on the one hand, and we are neglecting it on the other hand. Neglecting existence in the philosophy has misled it. The existent is the veil for the existence on the one hand, and it is the sign for it on the other hand. For thinking, we must approach the existent, but how is it possible? The only way to existence is “Dasein”. The fear- consciousness characteristic of Dasein is the condition for non-existence. When non-existence dominates Dasein, existence comes in and we become reminded of existence. Of course, existence is related to us even when we neglect it. In the light of the relationship of existence with human being, the essence of philosophy, the nature of the man, the essence of art and the essence of technique are established. At the end of the article, we review and investigate Heidegger’s views.
