Hilbert had never liked this gloomy philosophy. Now, with all the world (or at any rate the scientific-mathematical part of it) listening, he gave it a last resounding kick. We ought not believe those who today, with a philosophical air and a tone of superiority, prophesy the decline of culture, and are smug in their acceptance of the Ignorabimus principle. For us there is no Ignorabimus, and in my opinion there is none for the natural sciences either. In place of this foolish Ignorabimus, let our resolution be, to the contrary: “We must know, we shall know.”
