The 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 HeideggerIn the work of art the truth of an entity has set itself to work. ‘To set’ means here: to bring to a stand. Some particular entity, a pair of peasant shoes, comes in the work to stand in the light of its being. The being of the being comes into the steadiness of its shining. The nature of art would then be this: the truth of being setting itself to work.
