ONE:There are some crimes which are at the same time of common occurrence and of difficult proof. In them the difficulty of proof is equivalent to a probability of innocence; and the harm of their impunity being so much the less to be considered as their frequency depends on principles other than the risk of punishment, the time for inquiry and the period of prescription ought both to be proportionately less. Yet[161] cases of adultery and pederasty, both of difficult proof, are precisely those in which, according to received principles, tyrannical presumptions of quasi-proofs and half-proofs are allowed to prevail (as if a man could be half-innocent or half-guilty, in other words, half-punishable or half-acquittable); in which torture exercises its cruel sway over the person of the accused, over the witnesses, and even over the whole family of an unfortunate wretch, according to the coldly wicked teaching of some doctors of law, who set themselves up as the rule and standard for judges to follow.
Capital punishment being less general in the world now than torture was when Beccaria wrote, it seems to be a fair logical inference that it is already far advanced towards its total disappearance. For the same argument which Voltaire applied in the case of torture cannot fail sooner or later to be applied to capital punishment. If, he says, there were but one nation in the world which had abolished the use of torture; and if in that nation crimes were no more frequent than in others, its example would be surely sufficient for the rest of the world. England alone might instruct all other nations in this particular; but England is not the only nation. Torture has been abolished in other countries, and with success; the question, therefore, is decided. If in this argument we read capital punishment instead of torture, murders instead of crimes, and Portugal instead of England, we shall best appreciate that which is after all the strongest argument against capital punishment, namely, that it has been proved unnecessary for its professed object in so many countries that it might safely be relinquished in all.No law ought to be promulgated that has not force to back it, or that the nature of things deprives of validity; and as minds are ruled by opinion, which[224] itself follows the slow and indirect impressions of legislation, whilst it resists those that are direct and violent, the most salutary laws become infected with the contempt felt for useless laws, and are regarded rather as obstacles to be surmounted than as the deposit of the public welfare.3. When the proofs are independent of each otherthat is to say, when they do not derive their value one from the otherthen the more numerous the proofs adduced, the greater is the probability of the fact in question, because the falsity of one proof affects in no way the force of another. The reason for translating afresh Beccarias Dei Delitti e delle Pene (Crimes and Punishments) is, that it is a classical work of its kind, and that the interest which belongs to it is still far from being merely historical.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.
