Man is a credulous animal, and must believe something; in the absence of good grounds for belief, he will be satisfied with bad ones.
The human race may well become extinct before the end of the century. Speaking as a mathematician, I should say the odds are about three to one against survival.
But courage in fighting is by no means the only form, nor perhaps even the most important. There is courage in facing poverty, courage in facing derision, courage in facing the hostility of one's own herd. In these, the bravest soldiers are often lamentably deficient. And above all there is the courage to think calmly and rationally in the face of danger, and to control the impulse of panic fear or panic rage.
I don't like the spirit of socialism - I think freedom is the basis of everything.
Truth is for the gods; from our human point of view, it is an ideal, towards which we can approximate, but which we cannot hope to reach.
We must be sceptical even of our scepticism.
Ethics is in origin the art of recommending to others the sacrifices required for cooperation with oneself.
I've always thought respectable people scoundrels, and I look anxiously at my face every morning for signs of my becoming a scoundrel.
We all have a tendency to think that the world must conform to our prejudices. The opposite view involves some effort of thought, and most people would die sooner than think in fact they do so.
In the part of this universe that we know there is great injustice, and often the good suffer, and often the wicked prosper, and one hardly knows which of those is the more annoying.
The Ten Commandments should be headed like an examination paper: No more than six to be attempted.
From India to Spain, the brilliant civilization of Islam flourished. What was lost to christendom at this time was not lost to civilization, but quite the contrary.
The skill of the politician consists in guessing what people can be brought to think advantageous to themselves; the skill of the expert consists in calculating what really is advantageous, provided people can be brought to think so.
Always remember that true happiness is not in getting what you want, but wanting what you already have. He who dies with the most toys is still dead. What is wanted is not the will to believe, but the will to find out, which is the exact opposite.
Machines deprive us of two things which are certainly important ingredients of human happiness, namely, spontaneity and variety.
Who ever heard a theologian preface his creed, or a politician conclude his speech with an estimate of the probable error of his opinion?
It may seem to your conceited to suppose that you can do anything important toward improving the lot of mankind. But this is a fallacy. You must believe that you can help bring about a better world. A good society is produced only by good individuals, just as truly as a majority in a presidential election is produced by the votes of single electors. Everybody can do something toward creating in his own environment kindly feelings rather than anger, reasonableness rather than hysteria, happiness rather than misery.

The most savage controversies are about matters as to which there is no good evidence either way.
What else is there to make life tolerable? We stand on the shore of an ocean, crying to the night and to emptiness. Sometimes a voice of one drowning, and in a moment the silence returns. The world seems to me quite dreadful, the unhappiness of many people is very great, and I often wonder how they all endure it. It is usually the central thing around which their lives are built, and I suppose if they did not live most of their lives in the things of the moment, they would not be able to go on.
There can't be a practical reason for believing something that is not true.
