TWO:Would you prevent crimes, then see that enlightenment accompanies liberty. The evils that flow from knowledge are in inverse ratio to its diffusion; the benefits directly proportioned to it. A bold impostor, who is never a commonplace man, is adored by an ignorant people, despised by an enlightened one. Knowledge, by facilitating comparisons between objects and multiplying mens points of view, brings many different notions into contrast, causing them to modify one another, all the more easily as the same views and the same difficulties are observed in others. In the face of a widely diffused national enlightenment the calumnies of ignorance are silent, and authority, disarmed of pretexts for its manifestation, trembles; whilst the rigorous force of the laws remains unshaken, no one of education having any dislike to the clear and useful public compacts which secure the common safety, when he compares the trifling and useless liberty sacrificed by himself with the sum-total of all the liberties sacrificed by others, who without the laws might have been hostile to himself. Whoever has a sensitive soul, when he contemplates a code of well-made laws, and finds that he has only lost the pernicious liberty of injuring others, will feel[246] himself constrained to bless the throne and the monarch that sits upon it.As a matter of fact the law affords a very clear[81] proof, that its real purpose is to administer retributive justice and that punishment has no end beyond itself, by its careful apportionment of punishment to crime, by its invariable adjustment between the evil a man has done and the evil it deals out to him in return. For what purpose punish offences according to a certain scale, for what purpose stay to measure their gravity, if merely the prevention of crime is the object of punishment? Why punish a slight theft with a few months imprisonment and a burglary with as many years? The slight theft, as easier to commit, as more tempting accordingly, should surely have a harder penalty affixed to it than a crime which, as it is more difficult, is also less probable and less in need of strong counter-inducements to restrain it. That the law never reasons in this way is because it weighs offences according to their different degrees of criminality, or, in other words, because it feels that the fair retaliation for the burglary is not a fair retaliation for the theft.
