There was not an anomaly in our old criminal practice which was not based on this theorya theory which had, indeed, its precedent in the old Hebrew law that punished more severely a theft from a field than a theft from a house; and the first writer who protested against it was Eden, afterwards Lord Auckland, who in 1771 published his Principles of Penal Law, one of the best books ever written on the subject. The influence of Beccaria is apparent in Edens work, not only by his direct reference to it, but by his spirit of declared opposition to the actual practice of the law. Two instances of its tendency will suffice. Imprisonment, inflicted by law as a punishment, is not according to the principles of wise legislation. It sinks useful subjects into burthens on the community, and has always a bad effect on their morals; nor can it communicate the benefit of example, being in its nature secluded from the eye of the people. And again: Whatever exceeds simple death is mere cruelty. Every step beyond is a trace of ancient barbarity, tending only to distract the attention of the spectators and to lessen the solemnity of the example. There is no such thing as vindictive justice; the idea is shocking.All punishment is unjust that is unnecessary to the maintenance of public safety.

The first class of crimesthat is, the worst, because they are the most injurious to societyare those known as crimes of high treason. Only tyranny and ignorance, which confound words and ideas of the clearest meaning, can apply this name, and consequently the heaviest punishment, to different kinds of crimes, thus rendering men, as in a thousand other cases, the victims of a word. Every crime, be it ever so private, injures society; but every crime does not aim at its immediate destruction. Moral, like physical actions, have their limited sphere of activity, and are differently circumscribed, like all the movements of nature, by time and space; and therefore only a sophistical interpretation, which is generally the philosophy of slavery, can confound what eternal truth has distinguished by immutable differences.The third consequence is this: if it were proved that the severity of punishments were simply useless (to say nothing of being directly opposed to the public good and to the very object of preventing crimes), even in that case it would be contrary not only to those beneficent virtues that flow from an enlightened reason, which prefers to rule over happy human beings than over a flock of slaves, the constant victims of timid cruelty, but it would be also contrary to justice and to the nature of the social contract itself.
