To promote the contentment and comfort of congenital criminals within their asylum or prison home an alternative to celibacy might be offered, viz. surgical treatment, to render the male incapable of reproduction. (The treatment indicated is not the operation ordinarily performed upon some domestic animals; this, applied to human beings, would be morally and physically injurious. Particulars of the appropriate method were published in the _British Medical Journal_ as early as May 2, 1874, at p. 586.) Were this course voluntarily chosen, the sexes might intermingle without danger to posterity; and since fuller social life tends to make all human beings happier, these convicts would become more manageable, and coercive restraints cease to be indispensable. But the criminal stock is not great when compared with the actual crimes of to-day. Crime in a vast measure is simply produced by the outward accidental conditions of life—an evil environment and a grossly inadequate training. If we alter the environment of our masses—by establishing a new industrial system that banishes poverty from the land, by initiating a Malthusian and neo-Malthusian practice that puts the physical life on a healthy basis, by creating a family life suitable to man’s emotional nature, and supplying a true education that embraces scientific restraints on all anti-social tendencies—then, but not till then, will crime and the criminal type alike become things of the past. We are surrounded to-day in our reformatories and board schools, in our homes and on our streets, by children of naïvely-disobedient or rebellious tendency. These are the embryo criminals of a few years hence. When a clever romanticist makes one his hero, and describes the development of trickiness in the child, and how he uses it as a weapon of defence against the “polissman” whom he defies, trips up and otherwise evades (_Cleg Kelly_, by Crockett), we read the account without compunction, nay, we relish the humour of the situation, and half approve the issue! Yet this assuredly is no legitimate outcome of childish bravery and sportiveness. Our levity arises from the underlying conviction, or the universal feeling begotten of genetic evolution, that the policeman’s jurisdiction here is flagrantly inappropriate.
