To these several corollaries—that the various orders of control exercised over men have a common origin and a common function, are called out by co-ordinate necessities and co-exist in like stringency, decline together and decay together—it now only remains to add that they simultaneously become less needful. The social discipline which has already wrought out great changes in men, must go on eventually to work out greater ones. That daily curbing of the lower nature and culture of the higher, which out of cannibals and devil-worshippers has evolved philanthropists, lovers of peace, and haters of superstition, may be expected to evolve out of these, men as much superior to them as they are to their progenitors. The causes that have produced past modifications are still in action; must continue in action as long as there exists any incongruity between men’s desires and the requirements of the social state; and must eventually make them organically fit for the social state. As it is now needless to forbid man-eating, so will it ultimately become needless to forbid murder, theft, and the minor offences of our criminal code. Along with growth of human nature into harmony with the moral law, there will go decreasing need for judges and statute-books; when the right course has become the course spontaneously chosen, prospects of future reward or punishment will not be wanted as incentives; and when due regard for others has become instinctive, there will need no code of ceremonies to say how behaviour shall be regulated. * * * * *
