Science is a grand thing when you can get it; in its real sense one of the grandest words in the world. But what do these men mean, nine times out often, when they use it nowadays? When they say detection is a science? When they say criminology is a science? They mean getting outside a man and studying him as if he were a gigantic insect: in what they would call a dry impartial light, in what I should call a dead and dehumanized light. They mean getting a long way off him, as if he were a distant prehistoric monster; staring at the shape of his ‘criminal skull’ as if it were a sort of eerie growth, like the horn on a rhinoceros’s nose. When the scientist talks about a type, he never means himself, but always his neighbour; probably his poorer neighbour. I don’t deny the dry light may sometimes do good; though in one sense it’s the very reverse of science. So far from being knowledge, it’s actually suppression of what we know. It’s treating a friend as a stranger, and pretending that something familiar is really remote and mysterious. It’s like saying that a man has a proboscis between the eyes, or that he falls down in a fit of insensibility once every twenty-four hours.
