I merely wish to suggest that we should treat the criminal as we treat a man suffering from the plague. Each is a public danger, each must have his liberty curtailed until he has ceased to be a danger. But the man suffering from plague is an object of sympathy and commiseration, whereas the criminal is an object of execration. This is quite irrational. And it is because of this difference of attitude that our prisons are so much less successful in curing criminal tendencies than our hospitals are in curing disease.
