The ordinary way of experiencing time divides it into a series of present-at-hand now-points. Experienced in this way, the now-time (Jetzt-Zeit ) is totally emptied of meaning, rendered homogeneous, repetitive, one-dimensional: it becomes a decayed version of Plato’s “image of eternity”, a form of endless suffering, dull and meaningless, bereft of radical hope. Heidegger argues that neither the authentic “will be” nor the authentic “having-been” can be understood in terms of such a series of “now-times.” Thus, just as there is a fallen, pathological experience of the future and the present, so too there is a fallen, pathological memory-experience of the past: a way of remembering that is really, when more deeply experienced, a kind of forgetting; a way of relating to what is past which is incapable of receiving it in a way that is open to what it bears—the unrealized “potentialities-for-being,” the possible “destinies,” that the past always carries forward. Dasein’s “has-been” is not a reified past, exhausted and final, but that out of which futures are yet to be made.
