Perfect rationality consists, not in believing what is true, but in attaching to every proposition a degree of belief corresponding to its degree of credibility.

One man likes oysters, and another likes pineapples; this distinguishes between them. But when they think about the multiplication table, provided they think correctly, there is no difference between them. The irrational separates us, the rational unites us.

Undoubtedly the most important source of religion is fear; this can be seen in the present day, since anything that causes alarm is apt to turn people's thoughts to God. Battle, pestilence, and shipwreck all tend to make people religious.

what is the use of making everybody rich if the rich themselves are miserable?

Mathematics takes us still further from what is human into the region of absolute necessity, to which not only the actual world, but ever possible world, must conform.

In a man whose reasoning powers are good, fallacious arguments are evidence of bias.

Thus mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.

Most modern people think of religion as a consolation, but to Epicurus it was the opposite. Supernatural interference with the course of nature seemed to him a source of terror, and immortality fatal to the hope of release from pain. Accordingly he constructed an elaborate doctrine designed to cure men of the beliefs that inspire fear.

A child develops best when, like a young plant, he is left undisturbed in the same soil. Too much travel, too much variety of impressions, are not good for the young, and cause them as they grow up to become incapable of enduring fruitful monotony.

Everyone who realises at all what human life is must feel at some time the strange loneliness of every separate soul; and then the discovery in others of the same loneliness makes a new strange tie, and a growth of pity so warm as to be almost a compensation for what is lost.

Intelligence is impeded by any creed, no matter what, and kindness is inhibited by the belief in sin and punishment (this belief, by the way, is the only one that the Soviet Government has taken over from orthodox Christianity)

Like Spinoza, he has a certain kind of moral purity and loftiness, which is very impressive. He is always sincere, never shrill or censorious, invariably concerned to tell the reader, as simply as he can, what he believes to be important. Whatever one may think of him as a theoretical philosopher, it is impossible not to love him as a man. The life of Plotinus is known

In a hopeful age, great present evils can be endured, because it is thought that they will pass; but in a tired age even real goods lose their savour. The Stoic ethic suited the times of Epictetus and Marcus Aurelius, because its gospel was one of endurance rather than hope.

Toleration of minorities is an essential part of wise democracy, but a part which is not always sufficiently remembered.
