" The task of the grounding of Da-sein by way of thinking and poetry overcomes the question of possibility. That question—How is such and such possible?—is the last implementation of mathematical thinking, which is the result of the dominance of the proposition as such, which in turn is the result of the collapse of ἀλήθεια. "

― Martin Heidegger , Ponderings II-VI: Black Notebooks 1931-1938
