Since 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 HeideggerTo 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 HeideggerThinking begins only when we have come to know that reason, glorified for centuries, is the stiff-necked adversary of thought.
Martin HeideggerTeaching is more difficult than learning because what teaching calls for is this: to let learn. The real teacher, in fact, lets nothing else be learned than learning. His conduct, therefore, often produces the impression that we properly learn nothing from him, if by "learning" we now suddenly understand merely the procurement of useful information.
Martin Heidegger
