(We must know. We will know.)

What is the deep meaning of this quotes acording to Sir David Hilbert logics ?

Answer 1

That was in Hilbert's radio speech. He wanted to axiomatize the whole mathematics, and believed that every axiomatic system is decidable. So, in particular, every well formulated math problem has a solution. It was before G$\ddot{o}$del.
