…but this is the real objection to that torrent of modern talk about treating crime as disease, about making a prison merely a hygienic environment like a hospital, of healing sin by slow scientific methods. The fallacy of the whole thing is that evil is a matter of active choice whereas disease is not. If you say that you are going to cure a profligate as you cure an asthmatic, my cheap and obvious answer is, “Produce the people who want to be asthmatics as many people want to be profligates.” A man may lie still and be cured of a malady. But he must not lie still if he wants to be cured of a sin; on the contrary, he must get up and jump about violently. The whole point indeed is perfectly expressed in the very word which we use for a man in hospital; “patient” is in the passive mood; “sinner” is in the active. If a man is to be saved from influenza, he may be a patient. But if he is to be saved from forging, he must be not a patient but an impatient. He must be personally impatient with forgery. All moral reform must start in the active not the passive will.
