For the mathematician there is no Ignorabimus, and, in my opinion, not at all for natural science either … The true reason why no one has succeeded in finding an unsolvable problem is, in my opinion, that there is no unsolvable problem. In contrast to the foolish Ignorabimus, our credo avers: Wir müssen wissen. Wir werden wissen. [We must know. We shall know.]
Hilbert
