The third consequence is this: if it were proved that the severity of punishments were simply useless (to say nothing of being directly opposed to the public good and to the very object of preventing crimes), even in that case it would be contrary not only to those beneficent virtues that flow from an enlightened reason, which prefers to rule over happy human beings than over a flock of slaves, the constant victims of timid cruelty, but it would be also contrary to justice and to the nature of the social contract itself. In every criminal case a judge ought to form a complete syllogistic deduction, in which the statement of the general law constitutes the major premiss; the conformity or non-conformity of a particular action with the law, the minor premiss; and acquittal or punishment, the conclusion. When a judge is obliged, or of his own accord wishes, to make even no more than two syllogisms, the door is opened to uncertainty.


But there was one great fallacy, pervading our whole criminal law, which Blackstone left undetected and untouched. This was, that the severity of punishment must be augmented in proportion to the increase of temptation, and that the measure of the guilt of a crime lay in the facility with which it might be committed. Among crimes of an equal malignity, says Blackstone, those [deserve most punishment, as most injurious] which a man has the most frequent and easy opportunities of committing, which cannot so easily be guarded against as others, and which, therefore, the offender has the strongest inducement to commit. And on this principle he finds it reasonable, that, while the theft of a pocket-handkerchief should be a capital crime, the theft of a load of hay should only involve transportation. It is impossible to prevent all the disorders that may arise in the universal conflict of human passions. Their increase depends on that of population and on the crossings of private interests, which cannot be directed with geometrical exactness to the public welfare. In political arithmetic the calculation of probabilities must be substituted for mathematical exactness. Glance at the history of the world, and you will see disorders increase with the increase of the bounds of empire; thus national feeling being to the same extent diminished, the general inducement to crime increases with the greater interest of each individual in such disorders, and on this account the necessity for aggravating penalties ever continues to increase. Some remnants of the laws of an ancient conquering people, which a prince who reigned in Constantinople some 1,200 years ago caused to be compiled, mixed up afterwards with Lombard rites and packed in the miscellaneous volumes of private and obscure commentatorsthese are what form that set of traditional opinions which from a great part of Europe receive nevertheless the name of laws; and to this day it is a fact, as disastrous as it is common, that some opinion of Carpzovius, some old custom pointed out by Clarus, or some form of torture suggested in terms of complacent ferocity by Farinaccius, constitute the laws, so carelessly followed by those, who in all trembling ought to exercise their government over the lives and fortunes of men. These laws, the dregs of the most barbarous ages, are examined in this book in so far as regards criminal jurisprudence, and I have dared to expose their faults to the directors of the public happiness in a style which may keep at[112] a distance the unenlightened and intolerant multitude. The spirit of frank inquiry after truth, of freedom from commonplace opinions, in which this book is written, is a result of the mild and enlightened Government under which the Author lives. The great monarchs, the benefactors of humanity, who are now our rulers, love the truths expounded, with force but without fanaticism, by the obscure philosopher, who is only roused to indignation by the excesses of tyranny, but is restrained by reason; and existing abuses, for whosoever well studies all the circumstances, are the satire and reproach of past ages, and by no means of the present age or of its lawgivers.

CHAPTER XXVIII. OF INJURIES AND OF HONOUR. The greatest effect that any punishment has upon the human mind is not to be measured by its intensity but by its duration, for our sensibility is more easily and permanently affected by very slight but repeated impressions than by a strong but brief shock. Habit holds universal sway over every sentient being, and as we speak and walk and satisfy our needs by its aid, so moral ideas only stamp themselves on our mind by long and repeated impressions. It is not the terrible yet brief sight of a criminals death, but the long and painful example of a man deprived of[172] his liberty, who, having become as it were a beast of burthen, repays with his toil the society he has offended, which is the strongest restraint from crimes. Far more potent than the fear of death, which men ever have before their eyes in the remote distance, is the thought, so efficacious from its constant recurrence: I myself shall be reduced to as long and miserable a condition if I commit similar misdeeds. Any action that is not included between the two above-indicated extremes can only be called a crime or punished as such by those who find their interest in so calling it. The uncertainty of these limits has produced in different nations a system of ethics contrary to the system of laws, has produced many actual systems of laws at total variance with one another, and a quantity of laws which expose even the wisest man to the severest penalties. Consequently the words virtue and vice have become of vague and variable meaning, and from the uncertainty thus surrounding individual existence, listlessness and a fatal apathy have spread over political communities.

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.
