Accordingly he made a rapid journey back, leaving his companion to visit England alone; this expedition to Paris being the only event that ever broke the even tenor of his life. His French friends rather deserted him, Morellet in his memoirs going even so far as to speak of him as half-mad. But it was to his[25] friendship with the Verris that this journey to Paris was most disastrous, and nothing is more mournful than the petty jealousies which henceforth completely estranged from him his early friends. The fault seems to have rested mainly with the two brothers, whose letters (only recently published) reveal an amount of bitterness against Beccaria for which it is difficult to find any justification, and which disposes for ever of all claims of their writers to any real nobleness of character.[9] They complain to one another of Beccarias Parisian airs, of his literary pride, of his want of gratitude; they rejoice to think that his reputation is on the wane; that his illustrious friends at Paris send him no copies of their books; that he gets no letters from Paris; nay, they even go so far as to welcome the adverse criticisms of his Dei Delitti, and to hope that his golden book is shut up for ever.[10] Alessandro writes to his brother that all his thoughts are turned to the means of mortifying Beccaria; and the revenge the brothers think most likely to humiliate him is for Alessandro to extend the limits of his travels, so as to compare favourably with Beccaria in the eyes of the Milanese. They delight in calling him a madman, an imbecile, a harlequin; they lend a ready ear to all that gossip says in his[26] discredit.[11] In the most trifling action Pietro sees an intended slight, and is especially sore where his literary ambition is touched.[12] It angers him that Beccaria should receive praise for the Apology written against Facchinei, the work having been entirely written by himself, with some help from his brother, but with not so much as a comma from the hand of Beccaria.[13] Some books which Beccaria had brought to him from Paris he imagined were really gifts to him from the authors; he believed that DAlembert had sent him his Mlanges of his own accord, not at the request of Beccaria, as the latter had represented; but even Alessandro admits that it was concerning the books, as Beccaria had said.[14] In short, the whole correspondence shows that Pietro Verri was extremely jealous of the success which he himself had helped his friend to attain, and that disappointed literary vanity was the real explanation of his suddenly transmuted affection.

The credibility, therefore, of a witness must diminish in proportion to the hatred, friendship, or close connection between himself and the accused. More than one witness is necessary, because, so long as one affirms and another denies, nothing is proved, and the right which everyone has of being held innocent prevails.[140] The credibility of a witness becomes appreciably less, the greater the atrocity of the crime imputed,[66] or the improbability of the circumstances, as in charges of magic and gratuitously cruel actions. It is more likely, as regards the former accusation, that many men should lie than that such an accusation should be true, because it is easier for many men to be united in an ignorant mistake or in persecuting hatred than for one man to exercise a power which God either has not conferred or has taken away from every created being. The same reasoning holds good also of the second accusation, for man is only cruel in proportion to his interest to be so, to his hatred or[141] to his fear. Properly speaking, there is no superfluous feeling in human nature, every feeling being always in strict accordance with the impressions made upon the senses. In the same way the credibility of a witness may sometimes be lessened by the fact of his being a member of some secret society, whose purposes and principles are either not well understood or differ from those of general acceptance; for such a man has not only his own passions but those of others besides.

It was translated into English long ago; but the change in the order of the several chapters and paragraphs, which the work underwent before it was clothed in its final dress, is so great, that the new translation and the old one really constitute quite different books. Beccaria entertains a similar despair of truth. The history of mankind represents a vast sea of errors, in which at rare intervals a few truths only float uppermost; and the durability of great truths is as that of a flash of lightning when compared with the long[9] and dark night which envelops humanity. For this reason he is ready to be the servant of truth, not her martyr; and he recommends in the search for truth, as in the other affairs of life, a little of that philosophical indolence which cares not too much about results, and which a writer like Montaigne is best fitted to inspire.[6]

The lighting of a city by night at the public expense; the distribution of guards in the different quarters; simple moral discourses on religion, but only in the silent and holy quiet of churches, protected by public authority; speeches on behalf of private and public interests in national assemblies, parliaments, or wherever else the majesty of sovereignty residesall these are efficacious means for preventing the dangerous condensation of popular passions. These means are a principal branch of that magisterial vigilance which the French call police; but if this is exercised by arbitrary laws, not laid down in a code of general circulation, a door is opened to tyranny,[221] which ever surrounds all the boundaries of political liberty. I find no exception to this general axiom, that Every citizen ought to know when his actions are guilty or innocent. If censors, and arbitrary magistrates in general, are necessary in any government, it is due to the weakness of its constitution, and is foreign to the nature of a well organised government. More victims have been sacrificed to obscure tyranny by the uncertainty of their lot than by public and formal cruelty, for the latter revolts mens minds more than it abases them. The true tyrant always begins by mastering opinion, the precursor of courage; for the latter can only show itself in the clear light of truth, in the fire of passion, or in ignorance of danger. Howards book on the Lazarettos of Europe appeared four years after Paleys work. Although it did not deal directly with crimes, it indirectly treated of their connection with punishment. Howard was able to show that whilst in Middlesex alone 467 persons had been executed in nine years, only six had been executed in Amsterdam; that for a hundred years the average number of executions had been one a year at Utrecht and that for twenty-four years there had not even been one there. The inference therefore was that the diminution of punishment had a direct[58] effect in diminishing crime. Howard also advocated the restriction of capital punishment to cases of murder, arson, and burglary; highwaymen, footpads, and habitual thieves should, he thought, end their days in a penitentiary rather than on the gallows. Even this was a bold proposal, in a state of society yet in bondage to Paley.

Some crimes tend directly to the destruction of society or to the sovereign who represents it; others affect individual citizens, by imperilling their life, their property, or their honour; whilst others, again, are actions contrary to the positive or negative obligations which bind every individual to the public weal.
