But although the laws of every country thus recognise in different degrees the retributive nature of punishment, by their constant attention to its apportionment to crime, there is another corollary of the desirability of a just proportion between the two, which has never been, nor is ever likely to be, accepted: namely, that from the point of view of the public interest, which in theory is the only legal view, it is no mitigation of a crime that it is a first offence, nor any aggravation of one that it is the second.
ONE:The second epoch of history consists in the hard and terrible transition from errors to truth, from the darkness of ignorance to the light. The great clash between the errors which are serviceable to a few men of power and the truths which are serviceable to the weak and the many, and the contact and fermentation of the passions at such a period aroused, are a source of infinite evils to unhappy humanity. Whoever ponders on the different histories of the world, which after certain intervals of time are so much alike in their principal episodes, will therein frequently observe the sacrifice of a whole generation[248] to the welfare of succeeding ones, in the painful but necessary transition from the darkness of ignorance to the light of philosophy, and from despotism to freedom, which result from the sacrifice. But when truth, whose progress at first is slow and afterwards rapid (after mens minds have calmed down and the fire is quenched that purged a nation of the evils it suffered), sits as the companion of kings upon the throne, and is reverenced and worshipped in the parliaments of free governments, who will ever dare assert that the light which enlightens the people is more injurious than darkness, and that acknowledging the true and simple relations of things is pernicious to mankind?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.
As to the obscurity you find in the work, I heard, as I wrote, the clash of chains that superstition still shakes, and the cries of fanaticism that drown the voice of truth; and the perception of this frightful spectacle induced me sometimes to veil the truth in clouds. I wished to defend truth, without making myself her martyr. This idea of the necessity of obscurity has made me obscure sometimes without necessity. Add to this my inexperience and my want of practice in writing, pardonable in an author of twenty-eight,[3] who only five years ago first set foot in the career of letters.The result, then, of torture is a matter of temperament, of calculation, which varies with each man according[152] to his strength and sensibility; so that by this method a mathematician might solve better than a judge this problem: Given the muscular force and the nervous sensibility of an innocent man, to find the degree of pain which will cause him to plead guilty to a given crime.Whoever, therefore, shall wish to honour me with his criticisms, I would have begin with a thorough comprehension of the purpose of my worka purpose which, so far from diminishing legitimate authority, will serve to increase it, if opinion can effect more over mens minds than force, and if the mildness and humanity of the government shall justify it in the eyes of all men. The ill-conceived criticisms that have been published against this book are founded on confused notions, and compel me to interrupt for a moment the arguments I was addressing to my enlightened readers, in order to close once for all every door against the misapprehensions of timid bigotry or against the calumnies of malice and envy.Persons guilty of lesser crimes are usually either punished in the obscurity of a prison, or transported, as an example to nations who have given no offence, to a distant and therefore almost useless servitude. Since the gravest crimes are not those which men are tempted to commit on the spur of the moment, the public punishment of a great misdeed will be regarded by most men as strange and of impossible occurrence; but the public punishment of lighter crimes, to which mens thoughts more readily incline, will make an impression, which, at the same time that it diverts the mind from them, will restrain it still more from crimes of greater gravity. Punishments should not only be proportioned to one another and to crimes in point of force, but also in the mode of their infliction.
