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.

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

It was a reaction from the old idea of "protoplasm", a name which was a mere repository of ignorance.

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

In fact, words are well adapted for description and the arousing of emotion, but for many kinds of precise thought other symbols are much better.

My practise as a scientist is atheistic. That is to say, when I set up an experiment I assume that no god, angel, or devil is going to interfere with its course; and this assumption has been justified by such success as I have achieved in my professional career. I should therefore be intellectually dishonest if I were not also atheistic in the affairs of the world. And I should be a coward if I did not state my theoretical views in public.

This is my prediction for the future: Whatever hasn't happened will happen, and no one will be safe from it.
