Take it with money. Greed will certainly make a man want money, for the sake of a better house, better holidays, better things to eat and drink. But only up to a point. What is it that makes a man with £10,000 a year anxious to get £20,000 a year? It is not the greed or more pleasure. £10,000 will give all the luxuries that any man can really enjoy. It is Pride—the wish to be richer than some other rich man, and (still more) the wish for power. 1oi of course, power is what Pride really enjoys: there is nothing makes a man feel so superior to others as being able to move them about like toy soldiers. What makes a pretty girl spread misery wherever she goes by collecting admirers? Certainly not her sexual instinct: that kind of girl is quite often sexually frigid. It is Pride. What is it that makes a political leader or a whole nation go on and on, demanding more and more? Pride again. Pride is competitive by its very nature: that is why it goes on and on. If I am a proud man, then, as long as there is one man in the whole world more powerful, or richer, or cleverer than I, he is my rival and my enemy.
