In no way can it be uttered, as can other things, which one can learn. Rather, from out of a full, co-existential dwelling with the thing itself - as when a spark, leaping from the fire, flares into light - so it happens, suddenly, in the soul, there to grow, alone with itself.
Martin HeideggerThe threat to man does not come in the first instance from the potentially lethal machines and apparatus of technology. The actual threat has already affected man in his essence. The rule of Enframing threatens man with the possibility that it could be denied to him to enter into a more original revealing and hence to experience the call of a more primal truth
Martin HeideggerThe mathematical is that evident aspect of things within which we are always already moving and according to which we experience them as things at all, and as such things. The mathematical is this fundamental position we take toward things by which we take up things as already given to us, and as they must and should be given. Therefore, the mathematical is the fundamental presupposition of the knowledge of things.
Martin HeideggerFreedom is only to be found where there is burden to be shouldered. In creative achievements this burden always represents an imperative and a need that weighs heavily upon man’s mood, so that he comes to be in a mood of melancholy. All creative action resides in a mood of melancholy, whether we are clearly aware of the fact or not, whether we speak at length about it or not. All creative action resides in a mood of melancholy, but this is not to say that everyone in a melancholy mood is creative.
