The most sophisticated account of human temporality so far developed is set forth by Heidegger in Being and Time Heidegger has formed his conception by combining Kierkegaard's and Husserl's. He has used Kierkegaard's study of eternity in time as the inspiration for his notion of authentic temporality, and Husserl's phenomenology of internal time-consciousness for his description of inauthentic temporality. He has not, however, just combined these ideas eclectically; he has added his own account of a primordial temporality, which can misinterpret itself so as to appear to itself as dispersed in the way described by Husserl, or can reintegrate itself into the temporal structure discovered by Kierkegaard.
