THREE:It is, however, probable that the frequency of any crime bears little or no relation to the punishment affixed to it. Every criminal begins a new career, in which he thinks less of the nature of his punishment than of his chances of eluding it. Neither tradition nor example count with him for much in his balance of the chances in his own favour. The law can never be so certain in its execution as it is uncertain in its application, and it is the examples of impunity, not of punishment, to which men turn when they violate the law. So that whether the punishment for murder be an excruciating death, as in ancient Rome, or a mere fine, as in ancient England, the motives for escape are always the same, the means to effect it are always the same, and the belief in his power to effect it is correspondingly powerful in every criminal guilty of homicide.
THREE:As it, then, was necessity which constrained men to yield a part of their individual liberty, it is certain that each would only place in the general deposit the least possible portiononly so much, that is, as would suffice to induce others to defend it. The aggregate of these least possible portions constitutes the right of punishment; all that is beyond this is an abuse and not justice, a fact but not a right.[64] Punishments[124] which exceed what is necessary to preserve the deposit of the public safety are in their nature unjust; and the more just punishments are, the more sacred and inviolable is personal security, and the greater the liberty that the sovereign preserves for his subjects. 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.
THREE: One of the greatest preventives of crimes is, not the cruelty of the punishments attached to them, but their infallibility, and consequently that watchfulness on the part of the magistrates and that inexorable severity on the part of the judge which, to be a useful virtue, must coincide with a mild system of laws. The certainty of a punishment, moderate though it be, will ever make a stronger impression than the fear of another, more terrible, perhaps, but associated with the hope of impunity; for even the least evils when certain always terrify mens minds, and hope, that gift of heaven, which often makes up to us for everything, always throws into the distance the idea of greater evils, especially when its force is increased by impunity, which avarice and weakness so often grant.As it, then, was necessity which constrained men to yield a part of their individual liberty, it is certain that each would only place in the general deposit the least possible portiononly so much, that is, as would suffice to induce others to defend it.
