That Penology is still only in its experimental stage as a science, in spite of the progress it has made in recent times, is clear from the changes that are so constantly being made in every department of our penal system. We no longer mutilate nor kill our criminals, as our ancestors did in the plenitude of their wisdom; we have ceased to transport them, and our only study now is to teach them useful trades and laborious industry. Yet whether we shall better bring them to love labour by compulsory idleness or by compulsory work, whether short imprisonment or long is the most effective discipline, whether seclusion or association is least likely to demoralise them, these and similar questions have their answers in a quicksand of uncertainty. This only may experience be said to have yet definitely proved, that very little relation exists in any country between the given quantity of crime and the quantity or severity of punishment directed to its prevention. It has taken thousands of years to establish this truth, and even yet it is but partially recognised over the world.
Such are some of the problems connected with penology, which best illustrate the imperfection of its hitherto attained results. Only one thing as yet seems to stand out from the mist, which is, that closely associated as crime and punishment are both in thought and speech, they are but little associated in reality. The amount of crime in a country appears to be a given quantity, dependent on quite other causes than the penal laws directed to its repression. The efficiency of the latter seems proportioned[107] to their mildness, not to their severity; such severity being always spoiled by an inevitable moderation in practice. The conclusion, therefore, would seem to be, that a short simple code, with every punishment attached to every offence, with every motive for aggravation of punishment stated, and on so moderate a scale that no discretion for its mitigation should be necessary, would be the means best calculated to give to penal laws their utmost value as preventives of crime, though experience proves that as such preventives their place is a purely secondary one in a really good system of legislation.The following letter by Beccaria to the Abb Morellet in acknowledgment of the latters translation of his treatise is perhaps the best introduction to the life and character of the author. The letter in question has been quoted by Villemain in proof of the debt owed by the Italian literature of the last century to that of France, but from the allusions therein contained to Hume and the Spectator it is evident that something also was due to our own. Beccaria had spent eight years of his youth in the college of the Jesuits at Parma, with what sense of gratitude this letter will show. The following is a translation of the greater part of it:The first trace of Beccarias influence in England appeared in the first edition of Blackstones Commentaries, of which the book on the Criminal Laws[48] was published the very next year after the appearance of the Italian treatise. That Blackstone was well acquainted with it is proved by his frequent reference to it in treating of crimes. From Beccaria he argues that the certainty of punishments is more effectual than their severity, and finds it absurd to apply the same punishment to crimes of different malignity. Blackstone was also the first professional lawyer to find fault with the frequency of capital punishment in England, and to point out as a melancholy truth the presence of 160 actions in the statute book which were felonies without benefit of clergy.
