TWO: An error, not less common than it is contrary to the object of societythat is, to the consciousness of personal securityis leaving a magistrate to be the arbitrary executor of the laws, free at his pleasure to imprison a citizen, to deprive a personal enemy of his liberty on frivolous pretexts, or to leave a friend unpunished in spite of the strongest proofs of his guilt. Imprisonment is a punishment which, unlike every other, must of necessity precede the declaration of guilt; but this distinctive character does not deprive it of the other essential of punishment, namely, that the law alone shall determine the cases under which it shall be merited. It is for the law, therefore, to point out the amount of evidence of a crime which shall justify the detention of the accused, and his subjection to examination and punishment. For such detention there may be sufficient proofs in common[133] report, in a mans flight, in a non-judicial confession, or in the confession of an accomplice; in a mans threats against or constant enmity with the person injured; in all the facts of the crime, and similar indications. But these proofs should be determined by the laws, not by the judges, whose decisions, when they are not particular applications of a general maxim in a public code, are always adverse to political liberty. The more that punishments are mitigated, that misery and hunger are banished from prisons, that pity and mercy are admitted within their iron doors, and are set above the inexorable and hardened ministers of justice, the slighter will be the evidences of guilt requisite for the legal detention of the suspected. 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.
THREE:The result, then, of torture is a matter of temperament, of calculation, which varies with each man according[152] to his strength and sensibility; so that by this method a mathematician might solve better than a judge this problem: Given the muscular force and the nervous sensibility of an innocent man, to find the degree of pain which will cause him to plead guilty to a given crime.
THREE:Whosoever will read with a philosophical eye the codes and annals of different nations will find almost always that the names of virtue and vice, of good citizen and criminal, are changed in the course of ages, not in accordance with the changes that occur in the circumstances of a country, and consequently in conformity with the general interest, but in accordance with the passions and errors that have swayed different legislators in succession. He will observe full often, that the passions of one age form the basis of the morality of later ones; that strong passions, the offspring of fanaticism and enthusiasm, weakened and, so to speak, gnawed away by time (which reduces to a level all physical and moral phenomena) become little by little the prudence of the age, and a useful[204] instrument in the hand of the strong man and the clever. In this way the vaguest notions of honour and virtue have been produced; for they change with the changes of time, which causes names to survive things; as also with the changes of rivers and mountains, which form frequently the boundaries of moral no less than of physical geography.
