How much good it would do if one could exterminate the human race. - Bertrand Russell

I should like to say two things, one intellectual and one moral. The intellectual thing I should want to say is this: When you are studying any matter, or considering any philosophy, ask yourself only what are the facts and what is the truth that the facts bear out. Never let yourself be diverted either by what you wish to believe, or by what you think would have beneficent social effects if it were believed. But look only, and solely, at what are the facts. That is the intellectual thing that I should wish to say. The moral thing I should wish to say…I should say love is wise, hatred is foolish. In this world which is getting more closely and 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 a kind of charity and a kind of tolerance which is absolutely vital to the continuation of human life on this planet.

Why is propaganda so much more successful when it stirs up hatred than when it tries to stir up friendly feeling? The reason is clearly that the human heart as modern civilisation has made it is more prone to hatred than to friendship. And it is prone to hatred because it is dissatisfied, because it feels deply, perhaps even unconsciously, that it has somehow missed the meaning of life, that perhaps others, but not we ourselves, have secured the good things which nature offers man's enjoyment.

The world would be a happier place than it is if acquisitiveness were always stronger than rivalry. But in fact, a great many men will cheerfully face impoverishment if they can thereby secure complete ruin for their rivals. Hence the present level of taxation. Vanity is a motive of immense potency. Anyone who has much to do with children knows how they are constantly performing some antic, and saying "Look at me." "Look at me" is one of the most fundamental desires of the human heart. It can take innumerable forms, from buffoonery to the pursuit of posthumous fame.
