Max Planck

“Whence come I and whither go I? That is the great unfathomable question, the same for every one of us. Science has no answer to it.”

“It is not the possession of truth, but the success which attends the seeking after it, that enriches the seeker and brings happiness to him.”

“We have no right to assume that any physical laws exist, or if they have existed up until now, that they will continue to exist in a similar manner in the future.”

“Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: 'Ye must have faith.'”

“Scientific discovery and scientific knowledge have been achieved only by those who have gone in pursuit of it without any practical purpose whatsoever in view.”
