To think Being itself explicitly requires disregarding Being to the extent that it is only grounded and interpreted in terms of beings and for beings as their ground, as in all metaphysics.
Martin HeideggerThe question concerning technology is the question concerning the constellation in which revealing and concealing, in which the coming to presence of truth, comes to pass
Martin HeideggerSince time itself is not movement, it must somehow have to do with movement.Time is initially encountered in those entities which are changeable, change is in time. How is time exhibited in this way of encountering it, namely, as that within which things change? Does it here give itself as itself in what it is? Can an axplacation of time starts here guarantee that time will thereby provide as it were the fundamental phenomena that determine it in its own being?
Martin HeideggerBody', 'soul', and 'spirit' may designate phenomenal domains which can be detached as themes for definite investigations; within certain limits their ontological indefiniteness may not be important. When, however, we come to the question of man's Being, this is not something we can simply compute by adding together those kinds of Being which body, soul, and spirit respectively possess--kinds of being whose nature has not as yet been determined. And even if we should attempt such an ontological procedure, some idea of the Being of the whole must be presupposed.
