Because metaphysics knows only the truth of beings, and understands truth as objective correctness, it cannot experience the truth of beyng. It is constantly questioning beings, from the point of view of their what, why, how, whither and whence, of their causes, production, representation, and content. But it never questions them from the point of view of what is genuinely worthy of questioning, and which transforms the very sense of questioning. For when, Heidegger tells us, thinking is directed towards beyng, and appreciates what is question-worthy in questioning, it becomes thanking (Denken).
