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
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. – 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
Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve. – Max Planck
What I like about sceptics is that in good science you need critics that make you think: Crumbs, have I made a mistake here? If you dont have that continuously, you really are up the creek. The good sceptics have done a good service, but some of the mad ones I think have not done anyone any favours. – James Lovelock
