When he was a serf, they said to him, "Let me find you in this field: I will hang you if I find you in anyone else's field." But now he is a tramp they say to him, "You shall be jailed if I find you in anyone else's field: but I will not give you a field." They say, "You shall be punished if you are caught sleeping outside your shed: but there is no shed." If you say that modern magistracies could never say such mad contradictions, I answer with entire certainty that they do say them. A little while ago two tramps were summoned before a magistrate, charged with sleeping in the open air when they had nowhere else to sleep. But this is not the full fun of the incident. The real fun is that each of them eagerly produced about twopence, to prove that they could have got a bed, but deliberately didn't. To which the policeman replied that twopence would not have got them a bed: that they could not possibly have got a bed: and therefore (argued that thoughtful officer) they ought to be punished for not getting one. The intelligent magistrate was much struck with the argument: and proceeded to imprison these two men for not doing a thing they could not do. But he was careful to explain that if they had sinned needlessly and in wanton lawlessness, they would have left the court without a stain on their characters; but as they could not avoid it, they were very much to blame.

The desperate man to-day can do nothing. For you cannot agree with a maniac who sits on the bench with the straws sticking out of his hair and says, "Procure threepence from nowhere and I will give you leave to do without it."
