Without going further into this, which may briefly indicate some of the perplexities involved, I may mention certain cases in which there seems to be a real divergence of the two principles. There are cases in which the temptation may be fairly held to lessen guilt, and in which punishment has, notwithstanding, been made severer in consequence. The criminal law of the last century, for example, imposed a penalty of death upon persons who stole certain kinds of property left in specially exposed positions. The ease of taking it would very possibly tempt to theft men who would elsewhere be honest; and it was sought to compensate for the strength of the temptation by more savage punishment of those who yielded to it. Or, again, there are certain problems of a similar kind connected with political offences. A man who gets up a rebellion from sincere political motives is generally far better morally than the man who gets up a rebellion for the sake, say, of simple plunder. Ought the motive to be allowed as an extenuation of the offence? It ought, it may be said, from a moral point of view; but, from the point of view of simple deterrence, we might rather consider that the patriotic rebel is the more dangerous person of the two, and, therefore, requires the prospect of at least as heavy a punishment to keep him quiet. So, again, it has been asked, whether it should be admitted as an excuse for a rioter, that he has joined in violent courses under threats from the riotous mob. This is, of course, an excuse from the moralist's point of view; the man is only attacking the police in order to save his own house from being burnt, not from a disorderly or disaffected spirit. But it is replied, from the deterring point of view, that, if such an excuse be allowed, you are ceasing to threaten at the precise moment when the threats are most required. If the law is not to press from one side, all the pressure will come from the other, and every argument will be in favour of joining the side of disorder. Hence, it is argued, we ought to proportion the punishment, not to the offence, but to the temptation.
