TWO:If pleasure and pain are the motors of sensitive beings, if the invisible lawgiver of humanity has decreed rewards and punishments as one of the motives to impel men to even their noblest endeavours, the inexact distribution of these motives will give rise to that contradiction, as little noticed as it is of common occurrence, namely, that the laws punish crimes which are entirely of their own creation. If an equal penalty is attached to two crimes of unequal injury to society, the greater crime of the two, if it promise a greater advantage than the other, will have no stronger motive in restraint of its perpetration.[197] Whoever, for example, sees the same punishment of death decreed for the man who kills a pheasant and the man who slays his fellow or falsifies an important document, will draw no distinction between such crimes; and thus moral sentiments, the product only of many ages and of much bloodshed, the slowest and most difficult attainment of the human mind, dependent, it has been thought, on the aid of the most sublime motives and on a parade of the gravest formalities, will be destroyed and lost.A strange consequence that flows naturally from the use of torture is, that an innocent man is thereby placed in a worse condition than a guilty one, because if both are tortured the former has every alternative against him. For either he confesses the crime and is condemned, or he is declared innocent, having suffered an undeserved punishment. But the guilty man has one chance in his favour, since, if he resist the torture firmly, and is acquitted in consequence, he has exchanged a greater penalty for a smaller one. Therefore the innocent man can only lose, the guilty may gain, by torture.
THREE: 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.Two other fatal consequences flow from the cruelty of punishments, and are contrary to their very purpose, the prevention of crimes. The first is, that it is not so easy to preserve the essential proportion between crime and punishment, because, however much a studied cruelty may diversify its forms, none of them can go beyond the extreme limit of endurance which is a condition of the human organisation and sensibility. When once this extreme limit is attained, it would be impossible to invent such a corresponding increase of punishment for still more injurious and atrocious crimes as would be necessary to prevent them. The other consequence is, that impunity itself arises from the severity of punishments. Men are restrained within limits both in good and evil; and a sight too atrocious for humanity can only be a passing rage, not a constant system, such as the laws ought to be; if the latter are really cruel, either they are changed, or themselves give rise to a fatal impunity.
