“Like all his type, Newton was wholly aloof from women.”

A speculator is one who runs risks of which he is aware and an investor is one who runs risks of which he is unaware.

It is the long-term investor, who will in practice come in for the most criticism… For it is the essence of his behavior that he should be eccentric, unconventional, and rash in the eyes of average opinion.

Investment based on genuine long-term expectations is so difficult today as to be scarcely practicable.

Perhaps a day might come when there would be at last be enough to go round, and when posterity could enter into the enjoyment of our labors.

The day is not far off when the economic problem will take the back seat where it belongs, and the arena of the heart and the head will be occupied or reoccupied, by our real problems – the problems of life and of human relations, of creation and behavior and religion.

If you owe your bank a hundred pounds, you have a problem. But if you owe a million, it has.

I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas.

The important thing for Government is not to do things which individuals are doing already, and to do them a little better or a little worse; but to do those things which at present are not done at all.

Capitalism is the extraordinary belief that the nastiest of men, for the nastiest of reasons, will somehow work for the benefit of us all.

This long run is a misleading guide to current affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean is flat again.

For my own part, I believe that there is social and psychological justification for significant inequalities of incomes and wealth.

It has been pointed out already that no knowledge of probabilities, less in degree than certainty, helps us to know what conclusions are true, and that there is no direct relation between the truth of a proposition and its probability. Probability begins and ends with probability.

The duty of “saving” became nine-tenths of virtue and the growth of the cake the object of true religion.

I am not a scientist. I am, rather, an impresario of scientists.

Up until the First World War, when people turned anti-German, Germany had been described by American political scientists as the model of democracy.

Scientists – the crowd that for dash and style make the general public look like the Bloomsbury set.

Bohr’s influence on the physics and the physicists of our century was stronger than that of anyone else, even than that of Albert Einstein.

The left paw has done me well over the years. I’m not a scientist, I’m a martial artist.

As a scientist, I don’t believe science will ever discover whether God exists. Nor do I believe religion will ever prove it.

In this acausal world, scientists are helpless.

A computer scientist is a machine for converting coffee into urine.
