Those who staying with the wrong reward,(eg. stay in comfort zone, etc.), long enough will get problem.

I shall never believe that God plays dice with the world.

It is only men who are free, who create the inventions and intellectual works which to us moderns make life worth while.

I refuse to make money out of my science. My laurel is not for sale like so many bales of cotton.

I consider it important, indeed urgently necessary, for intellectual workers to get together, both to protect their own economic status and, also, generally speaking, to secure their influence in the political field.

Common sense invents and constructs no less than its own field than science does in its domain. It is, however, in the nature of common sense not to be aware of this situation.

If I could do it all again, I'd be a plumber.
