Quote by Hilbert, David

"Mathematics is the foundation of all knowledge."

"One should as a rule respect public opinion in so far as is necessary to avoid starvation and to prevent one's work from being suppressed, but anything that goes beyond this is voluntary submission to an unnecessary tyranny."

"The infinite! No other question has ever moved so profoundly the spirit of man."

"Out of the paradise that Cantor has created for us, no one shall expel us."

"Time waits for no one."

"Time spent with loved ones is never wasted."

"I've been alive for a long time. Long enough to know that you can't trust anyone."

"The past always catches up with you."
