The 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 HeideggerTime is not a thing, thus nothing which is, and yet it remains constant in its passing away without being something temporal like the beings in time.
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.

Therefore, the mathematical is the fundamental presupposition of the knowledge of things.
Martin Heidegger
