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."

"Lucy, you got some 'splainin' to do!"

"You must always be honest with the people you love."

"Truth always comes out in the end."

"Honesty is always the best policy."
