THREE:In the first place, our public works prisons, however excellent for their material results, are so many schools of crime, where for the one honest trade a man learns by compulsion he acquires a knowledge of three or four that are dishonest. I have become acquainted, says a released convict, with more of what is bad and evil, together with the schemes and dodges of professional thieves and swindlers, during the four years I served the Queen for nothing, than I should have done in fifty years outside the prison walls. The association rooms at Dartmoor are as bad as it is possible for anything to be they are really class-rooms in the college of vice, where all are alike students and professors. The present system in most instances merely completes the mans vicious and criminal education, instead of in the slightest degree reforming him.[56] It has been attempted in various ways to obviate this difficulty, by diminishing opportunities of companionship; but the real demoralisation of prison life is probably due less to the actual contact of bad men with one another than to the deadened sense of criminality which they derive from the feeling of numbers, just as from the same cause the danger of drowning is forgotten on the ice. Prisoners in gangs lose all shame of crime, just as men in armies forget their native horror of murder.There are three sources of the moral and political principles which govern mankind, namely, revelation, natural law, and social conventions. With regard to their principal object there is no comparison between the first and the other two, but they all resemble one another in this, that they all three conduce to the happiness of this present mortal life. To consider the different relations of social conventions is not to exclude those of revelation and natural law; rather it is the thousandfold changes which revelation and natural law, divine and immutable though they be, have undergone in the depraved mind of man, by his own fault, owing to false religions and arbitrary notions of virtue and vice, that make it appear necessary to examine, apart from all other considerations, the result of purely human conventions, expressed or implied, for the public need and welfare: this being an idea in which every sect and every moral system must necessarily agree; and it will always be a laudable endeavour, which seeks to constrain the headstrong and unbelieving to conform to the principles that induce men to live together in society. There are, then, three distinct kinds of virtue and vicethe religious, the natural, and the political. These three kinds ought never to conflict, although all the consequences and duties that flow from any one of them do not necessarily flow from the others. The natural law does not require all that revelation requires,[114] nor does the purely social law require all that natural law requires; but it is most important to distinguish the consequences of the conventional lawthat is, of the express or tacit agreements among menfrom the consequences of the natural law or of revelation, because therein lies the limit of that power, which can rightly be exercised between man and man without a special mandate from the Supreme Being. Consequently the idea of political virtue may, without any slur upon it, be said to be variable; that of natural virtue would be always clear and manifest, were it not obscured by the stupidity or the passions of men; whilst the idea of religious virtue remains ever one and the same, because revealed directly from God and by Him preserved.
