Dasein, Heidegger ' s conception of the human being

Martin Heidegger's Being and Time is one of the major influences on existential-phenomenological psychology's development due to its new approach to the understanding of the human being. The German philosopher called Dasein the particular human mode of being in order to rethink the western metaphysical (ontological) tradition. According to Heidegger, Dasein is always a relationship to one's own being, the characteristics of which are called existentials. In Being and Time Dasein is described in its everydayness as a being-in-the-world that is always already projecting itself upon possibilities of being which constitute one's own being. As a beingin- the-world Dasein does not show itself primarily as an individualized subject to whom the world is a mental object, on the contrary, it loses itself in the anonymity of The One and it establishes practical dealings with the surroundings. Individuation is something it has to achieve through the fundamental mood of anxiety.
