ONE: It is a great point in every good system of laws to determine exactly the credibility of witnesses and the proofs of guilt Every reasonable manthat is, every man with a certain connection between his ideas and with feelings like those of other menis capable of bearing witness. The true measure of his credibility is only the interest he has in speaking or in not speaking the truth; so that nothing can be more frivolous than to reject the evidence of women on the pretext of their feebleness, nothing more childish than to apply the results of real death to civil death as regards the testimony of the condemned, nothing more unmeaning than to insist on the mark of infamy in the infamous when they have no interest in lying.Finally, a man who, when examined, persists in an obstinate refusal to answer, deserves a punishment[146] fixed by the laws, and one of the heaviest they can inflict, that men may not in this way escape the necessary example they owe to the public. But this punishment is not necessary when it is beyond all doubt that such a person has committed such a crime, questions being useless, in the same way that confession is, when other proofs sufficiently demonstrate guilt And this last case is the most usual, for experience proves that in the majority of trials the accused are wont to plead Not guilty.
