THREE:No law ought to be promulgated that has not force to back it, or that the nature of things deprives of validity; and as minds are ruled by opinion, which[224] itself follows the slow and indirect impressions of legislation, whilst it resists those that are direct and violent, the most salutary laws become infected with the contempt felt for useless laws, and are regarded rather as obstacles to be surmounted than as the deposit of the public welfare.Lastly, a witnesss evidence is almost null when spoken words are construed into a crime. For the tone, the gesture, all that precedes or follows the different ideas attached by men to the same words, so alter and modify a mans utterances, that it is almost impossible to repeat them exactly as they were spoken. Moreover, actions of a violent and unusual character, such as real crimes are, leave their traces in the numberless circumstances and effects that flow from them; and of such actions the greater the number of the circumstances adduced in proof, the more numerous are the chances for the accused to clear himself. But words only remain in the memory of their hearers, and memory is for the most part unfaithful and often deceitful. It is on that account ever so much more easy to fix a calumny upon a mans words than upon his actions.
FORE: Our laws prohibit suggestive (leading) questions in a lawsuit: those, that is (according to the doctors of law), which, instead of applying, as they should do,[145] to the genus in the circumstances of a crime, refer to the species; those, in other words, which from their immediate connection with a crime suggest to the accused a direct answer. Questions, according to the criminal lawyers, ought, so to speak, to envelop the main fact spirally and never to attack it in a direct line. The reasons for this method are, either that an answer may not be suggested to the accused which may place him face to face with the charge against him, or perhaps because it seems unnatural for him directly to criminate himself. But, whichever of these reasons it may be, the contradiction is remarkable between the existence of such a custom and the legal authorisation of torture; for what interrogatory can be more suggestive than pain? The former reason applies to the question of torture, because pain will suggest to a strong man obstinate silence, in order that he may exchange the greater penalty for the lesser, whilst it will suggest to a weak man confession, in order that he may escape from present torment, which has more influence over him than pain which is to come. The other reason evidently applies too, for if a special question leads a man to confess against natural right, the agonies of torture will more easily do the same. But men are more governed by the difference of names than by that of things.The very severity of a punishment leads men to dare so much the more to escape it, according to the greatness of the evil in prospect; and many crimes are thus committed to avoid the penalty of a single one. Countries and times where punishments have been most severe have ever been those where the bloodiest and most inhuman deeds have been committed, the same spirit of ferocity that guided the hand of the legislator having guided also that of the parricide and assassin; on the throne dictating iron[168] laws for the villanous souls of slaves to obey, and in the obscurity of private life urging to the slaughter of tyrants, only to create fresh ones in their stead.
