In contrast to “Blessed are they who do not see and still believe,” he speaks of “seeing and still not believing.” - Martin Heidegger

...der Wille zur »wahren Welt« im Sinne Platons und des Christentums … ist in Wahrheit ein Neinsagen zu unserer hiesigen Welt, in der gerade die Kunst heimisch ist.

The word “art” does not designate the concept of a mere eventuality; it is a concept of rank.

But in fact there is no circle at all in the formulation of our question. Beings can be determined in their being without the explicit concept of the meaning of being having to be already available. If this were not so there could not have been as yet any ontological knowledge. And prob­ably no one would deny the factual existence of such knowledge. It is true that "being" is "presupposed" in all previous ontology, but not as an available concept-not as the sort of thing we are seeking.
