Such was legal opinion generally as expressed by its ablest representatives with respect to the due punishment for pocket-picking not a hundred years ago. It is easy now to smile at such errors, and, at the barren waste of wisdom spent in their defence, but what weight after that can be attached, on subjects of the general policy of the law, to the opinion of its chief professors? Can it be too much regretted that Lord Chief Justice Ellenborough should have sacrificed to his own authority, whilst alive, the authority of all judges ever destined to succeed him?
The close connection, therefore, of crime and punishment is of the utmost importance, if it be desirable that in rough and common minds there should, together with the seductive idea of an advantageous crime, immediately start up the associated idea of its punishment. Long delay has no other effect than the perpetual separation of these two ideas; and whatever the impression produced by the punishment of a crime, it produces it less as a punishment than as a sight, and only produces it when the horror of the particular crime, which would serve to strengthen the feeling of the punishment, has been weakened in the minds of the spectators.I know that those general principles which tend to enlighten and improve the human race are not absolutely useless that the enlightenment of nations is not without some effect on their rulers provided that the prerogative of the latter, their power, their security, their authority, their safety, is not touched thereby. I know well that this general enlightenment, so much boasted of, is a beautiful and glorious chimera, with which philosophers love to amuse themselves, but which would soon disappear if they would open history, and see therefrom to what causes improved institutions are due. The nations of antiquity have passed, and those of the present will pass, before philosophy and its influence have reformed a single government.There are some crimes which are at the same time of common occurrence and of difficult proof. In them the difficulty of proof is equivalent to a probability of innocence; and the harm of their impunity being so much the less to be considered as their frequency depends on principles other than the risk of punishment, the time for inquiry and the period of prescription ought both to be proportionately less. Yet[161] cases of adultery and pederasty, both of difficult proof, are precisely those in which, according to received principles, tyrannical presumptions of quasi-proofs and half-proofs are allowed to prevail (as if a man could be half-innocent or half-guilty, in other words, half-punishable or half-acquittable); in which torture exercises its cruel sway over the person of the accused, over the witnesses, and even over the whole family of an unfortunate wretch, according to the coldly wicked teaching of some doctors of law, who set themselves up as the rule and standard for judges to follow.
