"What is contrary to the visible truth must change or disappear—that’s the law of life.
If anyone thinks it’s really essential to build the life of human society on a foundation of lies, well, in my estimation, such a society is not worth preserving. If, on the other hand, one believes that truth is the indispensable foundation, then conscience bids one intervene in the name of truth, and exterminate the lie. Periods that have endured such affronts without protesting will be condemned by people of the coming generations.
I shall never believe that what is founded on lies can endure for ever. I believe in truth. I’m sure that, in the long run, truth must be victorious.
Research must remain free and unfettered by any State restriction. The facts which it establishes represent Truth, and Truth is never evil. The man of research is by nature extremely cautious; he never ceases to work, to ponder, to weigh and to doubt, and his suspicious nature breeds in him an inclination towards solitude and most rigorous self-criticism."
— Adolf Hitler, from Hitler’s Table Talk, 1941-1944: His Private Conversations
