Another way in which I tried to define the crank was that he always begins at the wrong end. He never knows the right way to take hold of anything, as one takes hold of a cat by the scruff of the neck. He always tries to catch his cat by the tail; especially if it is a Manx cat. The thing he begins with is always the thing that is last — and least. Thus, if he is talking about the ancient and lawful bond between man and woman, he will talk about votes before he talks about vows. Thus, if he is talking about children, he will be genuinely interested in the children’s schools; it will never so much as cross his mind that children, as a class, generally belong to families. If he is interested in Shakespeare, he will not be interested in Shakespeare’s poetry; he will be interested in the extraordinary question of who wrote it. If he is interested in one of the Gospels or in one of the Epistles, he will not be interested in what is written there; he will be interested in some bottomless bosh about when it was written. It was when I had got thus far in my speculations that I began to suspect that I had found out the definition of the crank after all.
The true and horrid secret of the crank is this: that he is not interested in his subject. He is only interested in his object. He wants to do something, to alter something, to feel he has made a difference, to rediscover his own miserable existence. He does not care for women, but for Votes for Women; he does not care for children, but for education; he does not care for animals, but for anti-vivisection; he does not care for Nature, but for “open spaces”. He does not care for anything unless he can do something to it. Leave him for three minutes alone with a cow or a canary, and he has not enough energy to live the life of contemplation. He can never enjoy a discussion because he can never enjoy a doubt.
