THREE: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 VIII.
