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.CHAPTER XXXII. OF DEBTORS.
FORE:Offences, therefore, against personal security and liberty are among the greatest of crimes. Under this head fall not only the assassinations and thefts of the common people, but those also committed by the nobles and magistrates, whose influence, acting with greater force and to a greater distance, destroys in those subject to them all ideas of justice and duty, and gives strength to those ideas of the right of the strongest, which are equally perilous ultimately to him who exercises no less than to him who endures it.Some crimes are injuries to a mans person, others to his property, and the former should certainly be punished by corporal punishments.
[32]But whether the international extradition of criminals be useful I would not venture to decide, until laws more in conformity with the needs of humanity, until milder penalties, and until the emancipation of law from the caprice of mere opinion, shall have given[194] security to oppressed innocence and hated virtue; until tyranny shall have been confined, by the force of universal reason which ever more and more unites the interests of kings and subjects, to the vast plains of Asia; however much the conviction of finding nowhere a span of earth where real crimes were pardoned might be the most efficacious way of preventing their occurrence. Infamy is a sign of public disapprobation, depriving a criminal of the good-will of his countrymen, of their confidence, and of that feeling almost of fraternity that a common life inspires. It does not depend upon the laws. Hence the infamy which the laws inflict should be the same as that which arises from the natural relations of things, the same as that taught by universal morality, or by that particular morality, which depends on particular systems, and sets the law for ordinary opinions or for this and that nation. If the one kind of infamy is different from the other, either the law loses in public esteem, or the ideas of morality and honesty disappear, in spite of declamations, which are never efficacious against facts. Whoever declares actions to be infamous which are in themselves indifferent, detracts from the infamy of actions that are really in themselves infamous.I know that those general principles which tend to enlighten and improve the human race are not absolutely useless that the enlightenment of nations is not without some effect on their rulers provided that the prerogative of the latter, their power, their security, their authority, their safety, is not touched thereby. I know well that this general enlightenment, so much boasted of, is a beautiful and glorious chimera, with which philosophers love to amuse themselves, but which would soon disappear if they would open history, and see therefrom to what causes improved institutions are due. The nations of antiquity have passed, and those of the present will pass, before philosophy and its influence have reformed a single government.
