Why? Surely they can find other men. Russell's reply when asked "if it wasn't unkind of him to love and leave so many women";

To choose one sock from each of infinitely many pairs of socks requires the Axiom of Choice, but for shoes the Axiom is not needed.

Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a deep ocean of anguish, reaching to the very verge of despair.

No man who believes that all is for the best in this suffering world can keep his ethical values unimpaired, since he is always having to find excuses for pain and misery.

I dislike Communism because it is undemocratic, and capitalism because it favors exploitation.

Better red than dead.

"I don't want to! Why should I?" "Because more people will be happier if you do than if you don't." "So what? I don't care about other people." "You should." "But why?" "Because more people will be happier if you do than if you don't."

Democracy is the process by which people choose the man who'll get the blame.

He asked my religion and I replied 'agnostic'. He asked how to spell it, and remarked with a sigh: 'Well, there are many religions, but I suppose they all worship the same God. This remark kept me cheerful for about a week.

Even when the experts all agree, they may well be mistaken.

I am writing to you to tell you of my decision to return to your Government the Carl von Ossietzsky medal for peace. I do so reluctantly and after two years of private approaches on behalf of Heinz Brandt, whose continued imprisonment is a barrier to coexistence, relaxation of tension and understanding between East and West... I regret not to have heard from you on this subject. I hope that you will yet find it possible to release Brandt through an amnesty which would be a boon to the cause of peace and to your country.

None but a coward dares to boast that he has never known fear.

It's not the experience that happens to you: it's what you do with the experience that happens to you.

In all affairs - love, religion, politics, or business - it's a healthy idea, now and then, to hang a question mark on the things you have long taken for granted.

We later learned that all the nineteen passengers in the non-smoking compartment had been killed. When the plane had hit the water a hole had been made in the plane and the water had rushed in. I had told a friend at Oslo who was finding me a place that he must find me a place where I could smoke, remarking jocularly, 'If I cannot smoke, I shall die'. Unexpectedly, this turned out to be true.

It seems that sin is geographical. From this conclusion, it is only a small step to the further conclusion that the notion of "sin" is illusory, and that the cruelty habitually practised in punishing it is unnecessary.

In the name of national security, the Commission's hearings were held in secret, thereby continuing the policy which has marked the entire course of the case. This prompts my second question: If, as we are told, Oswald was the lone assassin, where is the issue of national security? Indeed, precisely the same question must be put here as was posed in France during the Dreyfus case: If the Government is so certain of its case, why has it conducted all its inquiries in the strictest secrecy? "

Yes, if you happen to be interested in philosophy and good at it, but not otherwise - but so does bricklaying. Anything you're good at contributes to happiness. When asked "Does philosophy contribute to happiness?"

If there were in the world today any large number of people who desired their own happiness more than they desired the unhappiness of others, we could have a paradise in a few years.

I have lived in the pursuit of a vision, both personal and social. Personal: to care for what is noble, for what is beautiful, for what is gentle; to allow moments of insight to give wisdom at more mundane times. Social: to see in imagination the society that is to be created, where individuals grow freely, and where hate and greed and envy die because there is nothing to nourish them. These things I believe, and the world, for all its horrors, has left me unshaken.

Freedom of opinion can only exist when the government thinks itself secure...

The politician may change sides so frequently as to find himself always in the majority, but most politicians have a preference for one party to the other, and subordinate their love of power to this preference.

We invite this Congress, and through it the scientists of the world and the general public, to subscribe to the following resolution: "In view of the fact that in any future world war nuclear weapons will certainly be employed, and that such weapons threaten the continued existence of mankind, we urge the governments of the world to realize, and to acknowledge publicly, that their purpose cannot be furthered by a world war, and we urge them, consequently, to find peaceful means for the settlement of all matters of dispute between them".

Thank you for your letter and for the enclosure which I return herewith. I have been wondering whether there is any means of preventing the confusion between you and me, and I half-thought that we might write a joint letter to The Times in the following terms: Sir, To prevent the continuation of confusions which frequently occur, we beg to state that neither of us is the other. Do you think this would be a good plan?

Our great democracies still tend to think that a stupid man is more likely to be honest than a clever man, and our politicians take advantage of this prejudice by pretending to be even more stupid than nature made them.

I do not think it possible to get anywhere if we start from scepticism. We must start from a broad acceptance of whatever seems to be knowledge and is not rejected for some specific reason.

All human activity is prompted by desire. There is a wholly fallacious theory advanced by some earnest moralists to the effect that it is possible to resist desire in the interests of duty and moral principle. I say this is fallacious, not because no man ever acts from a sense of duty, but because duty has no hold on him unless he desires to be dutiful. If you wish to know what men will do, you must know not only, or principally, their material circumstances, but rather the whole system of their desires with their relative strengths.

We are speaking on this occasion, not as members of this or that nation, continent, or creed, but as human beings, members of the species Man, whose continued existence is in doubt.

Perhaps the best hope for the future of mankind is that ways will be found of increasing the scope and intensity of sympathy.

The harm that is done by a religion is of two sorts, the one depending on the kind of belief which it is thought ought to be given to it, and the other upon the particular tenets believed. As regards the kind of belief: it is thought virtuous to have faith-that is to say, to have a conviction which cannot be shaken by contrary evidence. Or, if contrary evidence might induce doubt, it is held that contrary evidence must be suppressed.

The essence of the Liberal outlook lies not in what opinions are held, but in how they are held: instead of being held dogmatically, they are held tentatively, and with a consciousness that new evidence may at any moment lead to their abandonment.

If throughout your life you abstain from murder, theft, fornication, perjury, blasphemy, and disrespect toward your parents, your church, and your king, you are conventionally held to deserve moral admiration even if you have never done a single kind or generous or useful action. This very inadequate notion of virtue is an outcome of taboo morality, and has done untold harm.

You, your families, your friends and your countries are to be exterminated by the common decision of a few brutal but powerful men. To please these men, all the private affections, all the public hopes, all that has been achieved in art, and knowledge and thought and all that might be achieved hereafter is to be wiped out forever. Our ruined lifeless planet will continue for countless ages to circle aimlessly round the sun unredeemed by the joys and loves, the occasional wisdom and the power to create beauty which have given value to human life.

What is serious about excitement is that so many of its forms are destructive. It is destructive in those who cannot resist excess in alcohol or gambling. It is destructive when it takes the form of mob violence. And above all it is destructive when it leads to war. It is so deep a need that it will find harmful outlets of this kind unless innocent outlets are at hand. There are such innocent outlets at present in sport, and in politics so long as it is kept within constitutional bounds. But these are not sufficient, especially as the kind of politics that is most exciting is also the kind that does most harm. Civilized life has grown altogether too tame, and, if it is to be stable, it must provide harmless outlets for the impulses which our remote ancestors satisfied in hunting.

When I was a child the atmosphere in the house was one of puritan piety and austerity. There were family prayers at eight o'clock every morning. Although there were eight servants, food was always of Spartan simplicity, and even what there was, if it was at all nice, was considered too good for children. For instance, if there was apple tart and rice pudding, I was only allowed the rice pudding. Cold baths all the year round were insisted upon, and I had to practice the piano from seven-thirty to eight every morning although the fires were not yet lit. My grandmother never allowed herself to sit in an armchair until the evening. Alcohol and tobacco were viewed with disfavor although stern convention compelled them to serve a little wine to guests. Only virtue was prized, virtue at the expense of intellect, health, happiness, and every mundane good.

There is no need to worry about mere size. We do not necessarily respect a fat man more than a thin man. Sir Isaac Newton was very much smaller than a hippopotamus, but we do not on that account value him less.

The criminal law has, from the point of view of thwarted virtue, the merit of allowing an outlet for those impulses of aggression which cowardice, disguised as morality, restrains in their more spontaneous forms. War has the same merit. You must not kill you neighbor, whom perhaps you genuinely hate, but by a little propaganda this hate can be transferred to some foreign nation, against whom all your murderous impulses become patriotic heroism.

I must before I die, find some way to say the essential thing that is in me, that I have never said yet - a thing that is not love or hate or pity or scorn, but the very breath of life, fierce and coming from far away, bringing into human life the vastness and fearful passionless force of non-human things...

Man differs from other animals in one very important respect, and that is that he has some desires which are, so to speak, infinite, which can never be fully gratified, and which would keep him restless even in Paradise. The boa constrictor, when he has had an adequate meal, goes to sleep, and does not wake until he needs another meal. Human beings, for the most part, are not like this.

The world is full of conflicts; and, overshadowing all minor conflicts, the titanic struggle between Communism and anti-Communism. Almost everybody who is politically conscious has strong feelings about one or more of these issues; but we want you, if you can, to set aside such feelings and consider yourselves only as members of a biological species which has had a remarkable history, and whose disappearance none of us can desire. We shall try to say no single word which should appeal to one group rather than to another. All, equally, are in peril, and, if the peril is understood, there is hope that they may collectively avert it.

Politics is concerned with herds rather than with individuals, and the passions which are important in politics are, therefore, those in which the various members of a given herd can feel alike.

The conviction that it is important to believe this or that, even if a free inquiry would not support the belief, is one which is common to almost all religions and which inspires all systems of state education. The consequence is that the minds of the young are stunted and are filled with fanatical hostility both to those who have other fanaticisms, and, even more virulently, to those who object to all fanaticisms.

A man might say, with enough truth to justify a joke: "Science is what we know, and philosophy is what we don't know." But it should be added that philosophical speculation as to what we do not yet know has shown itself a valuable preliminary to exact scientific knowledge.

Suppose atomic bombs had reduced the population of the world to one brother and one sister, should they let the human race die out? I do not know the answer, but I do not think it can be in the affirmative merely on the ground that incest is wicked.

We used to think that Hitler was wicked when he wanted to kill all the Jews, but what Kennedy and Macmillan and others both in the East and in the West pursue policies which will probably lead to killing not only all the Jews but all the rest of us too. They are much more wicked than Hitler and this idea of weapons of mass extermination is utterly and absolutely horrible and it is a thing which no man with one spark of humanity can tolerate and I will not pretend to obey a government which is organising the massacre of the whole of mankind. I will do anything I can to oppose such Governments in any non-violent way that seems likely to be fruitful, and I should exhort all of you to feel the same way. We cannot obey these murderers. They are wicked and abominable. They are the wickedest people that ever lived in the history of man and it is our duty to do what we can.

It is normal to hate what we fear, and it happens frequently, though not always, that we fear what we hate. I think it may be taken as the rule among primitive men, that they both fear and hate whatever is unfamiliar. They have their own herd, originally a very small one. And within one herd, all are friends, unless there is some special ground of enmity. Other herds are potential or actual enemies; a single member of one of them who strays by accident will be killed. An alien herd as a whole will be avoided or fought according to circumstances. It is this primitive mechanism which still controls our instinctive reaction to foreign nations. The completely untravelled person will view all foreigners as the savage regards a member of another herd. But the man who has travelled, or who has studied international politics, will have discovered that, if his herd is to prosper, it must, to some degree, become amalgamated with other herds.

I was a solitary, shy, priggish youth. I had no experience of the social pleasures of boyhood and did not miss them. But I liked mathematics, and mathematics was suspect because it has no ethical content. I came also to disagree with the theological opinions of my family, and as I grew up I became increasingly interested in philosophy, of which they profoundly disapproved. Every time the subject came up they repeated with unfailing regularity, 'What is mind? No matter. What is matter? Never mind.' After some fifty or sixty repetitions, this remark ceased to amuse me.

When I was 4 years old ... I dreamt that I'd been eaten by a wolf, and to my great surprise I was in the wolf's stomach and not in heaven.

Children are made to learn bits of Shakespeare by heart, with the result that ever after they associate him with pedantic boredom. If they could meet him in the flesh, full of jollity and ale, they would be astonished, and if they had never heard of him before they might be led by his jollity to see what he had written. But if at school they had been inoculated against him, they will never be able to enjoy him. The same sort of thing applies to music lessons. Human beings have certain capacities for spontaneous enjoyment, but moralists and pedants possess themselves of the apparatus of these enjoyments, and having extracted what they consider the poison of pleasure they leave them dreary and dismal and devoid of everything that gives them value. Shakespeare did not write with a view to boring school-children; he wrote with a view to delighting his audiences. If he does not give you delight, you had better ignore him.

The moral things I wish to say to future generations is very simple. I should say love is wise hatred is foolish. In this world which is getting more and more closely interconnected, we have to learn to tolerate each other. We have to learn to put up with the fact that some people say things that we don't like. We can only live together in that way, and if we are to live together and not die together we must learn the kind of charity and kind of tolerance which is absolutely vital to the continuation of human life on this planet.
