Money can buy a fine dog but it is kindness that makes him wag his tail.

Man armed with science is like a baby with a box of matches.

Science affects the average man and woman in two ways already. He or she benefits by its application driving a motor-car or omnibus instead of a horse-drawn vehicle, being treated for disease by a doctor or surgeon rather than a witch, and being killed with an automatic pistol or shell in place of a dagger or a battle-axe.

I have come to the conclusion that my subjective account of my motivation is largely mythical on almost all occasions. I don't know why I do things.

And if we must educate our poets and artists in science, we must educate our masters, labour and capital, in art.

The future will be no primrose path. It will have its own problems. Some will be the secular problems of the past, giant flowers of evil blossoming at last to their own destruction. Others will be wholly new.

The advance of scientific knowledge does not seem to make either our universe or our inner life in it any less mysterious.
