Even the idea of public utility as the final test and standard of morality is derived from Beccaria, and the famous expression, the greatest happiness of the greatest number, occurs, in capital letters, in the very first page of the Delitti e delle Pene.[30] Bentham himself fully acknowledged this. Priestley was the first, he says, unless it was Beccaria, who taught my lips to pronounce this sacred truth: that the[47] greatest happiness of the greatest number is the foundation of morals and happiness. And with reference to his idea of the measurable value of different pains and pleasures, he says: It was from Beccarias little treatise on Crimes and Punishments that I drew, as I well remember, the first hint of this principle, by which the precision and clearness and incontestableness of mathematical calculations are introduced for the first time into the field of morals.[19]This essay on the Imagination was published soon after the Crimes and Punishments in the periodical to which Beccaria alludes in his letter to Morellet. The Caff was the name of the periodical which, from June 1764, he and his friends published every tenth day for a period of two years. The model of the paper was the English Spectator, and its object to propagate useful knowledge pleasantly among the Milanese, whilst its name rested on the supposition that the friends who composed it executed their labours during meetings in a coffee-house. The most interesting contributions to it by Beccaria are his Fragment on Style, his article on Periodical Newspapers, and his essay on the Pleasures of the Imagination.CHAPTER XXVIII. OF INJURIES AND OF HONOUR. From the simple consideration of the truths hitherto demonstrated it is evident that the object of punishment is neither to torment and inflict a sensitive creature nor to undo a crime already committed. Can he, whose function it is, so far from acting from passion, to tranquillise the private passions of his fellows, harbour in the body politic such useless cruelty, the instrument either of furious fanatics or of weak tyrants? Shall perchance the shrieks of an unhappy wretch call back from never-receding time actions already executed? The object, therefore, of punishment is simply to prevent the criminal from injuring anew his fellow-citizens, and to deter others from committing similar injuries; and those punishments and that method of inflicting them should be preferred which, duly proportioned to the offence, will produce a more efficacious and lasting impression on the[166] minds of men and inflict the least torture on the body of a criminal. If the interpretation of laws is an evil, it is clear that their obscurity, which necessarily involves interpretation, must be an evil also, and an evil which will be at its worst where the laws are written in any other than the vernacular language of a country. For in that case the people, being unable to judge of themselves how it may fare with their liberty or their limbs, are made dependent on a small class of men; and a book, which should be sacred and open to all, becomes, by virtue of its language, a private and, so to speak, a family manual.
