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

We must learn not to take traditional morals too seriously. And it is just because even the least dogmatic of religions tends to associate itself with some kind of unalterable moral tradition, that there can be no truce between science and religion.

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

Teleology is like a mistress to a biologist: he cannot live without her but he's unwilling to be seen with her in public.

My final word, before I'm done, Is "Cancer can be rather fun"- Provided one confronts the tumour with a sufficient sense of humour. I know that cancer often kills, But so do cars and sleeping pills; And it can hurt till one sweats, So can bad teeth and unpaid debts. A spot of laughter, I am sure, Often accelerates one's cure; So let us patients do our bit To help the surgeons make us fit.

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

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