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. – Max Planck
A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it. – Max Planck
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. – Max Planck
