An Essay on Crimes and Punishments/Chapter XXII
CHAPTER XXXII.
Of Robbery.
THE punishment of robbery, not accompanied with violence, should be pecuniary. He who endeavours to enrich himself with the property of another, should be deprived of part of his own. But this crime, alas! is commonly the effect of misery and despair; the crime of that unhappy part of mankind, to whom the right of exclusive property (a terrible, and perhaps unnecessary right) has left but a bare existence. Besides, as pecuniary punishments may increase the number of poor, and may deprive an innocent family of subsistence, the most proper punishment will be that kind of slavery, which alone can be called just; that is, which makes the society, for a time, absolute master of the person and labour of the criminal, in order to oblige him to repair, by this dependence, the unjust despotism he usurped over the property of another, and his violation of the social compact.
When robbery is attended with violence, corporal punishment should be added to slavery. Many writers have shown the evident disorder which must arise from not distinguishing the punishment due to robbery with violence, and that due to theft or robbery committed with dexterity, absurdly making a sum of money equivalent to a man’s life. But it can never be superfluous to repeat, again and again, those truths of which mankind have not profited; for political machines preserve their motion much longer than others, and receive a new impulse with more difficulty. These crimes are in their nature absolutely different, and this axiom is as certain in politics as in mathematics, that between qualities of different natures there can be no similitude.
