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 XXIII. PROPORTION BETWEEN CRIMES AND PUNISHMENTS.These problems deserve to be solved with such geometrical precision as shall suffice to prevail over the clouds of sophistication, over seductive eloquence, or timid doubt. Had I no other merit than that of having been the first to make clearer to Italy that which other nations have dared to write and are beginning to practise, I should deem myself fortunate;[121] but if, in maintaining the rights of men and of invincible truth, I should contribute to rescue from the spasms and agonies of death any unfortunate victim of tyranny or ignorance, both so equally fatal, the blessings and tears of a single innocent man in the transports of his joy would console me for the contempt of mankind.Ramsay was so far right, that whether a revolution was the only hope for theories like Beccarias or[21] not, the realisation of many of them was one of the first results of that general revolution, which seemed to Ramsay so impossible and undesirable. His letter, as it is a characteristic expression of that common apathy and despair of change which afflict at times even the most sanguine and hopeful, so it is, from its misplaced despair, a good cure for moods of like despondency. For the complete triumph of Beccarias theories about torture, to say nothing of other improvements in law that he lived to witness, is perhaps the most signal instance in history of the conquest of theory over practice. For albeit that his theory was at total variance with the beliefs and ideas of the whole practical school, Beccaria lived to see torture abolished, not only in Lombardy and Tuscany, but in Austria generally, in Portugal and in Sweden, in Russia as well as in France. Yet Ramsays fears at the time were more reasonable than the hopes of Beccaria.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.
