As is the life that legalism expects us to lead, so is the scheme of rewards and punishments by which (as we have already seen) it constrains us to lead it. The materialisation of life that takes place under the sway of the Law is accurately matched and measured by the materialisation of the doctrine of moral retribution. The general idea that virtue is rewarded and vice punished is profoundly true. But the idea is easily misinterpreted; and it necessarily shares in the degradation of one's general conception of life. Virtue rewards the virtuous by making them more virtuous. Vice punishes the vicious by making them more vicious. So long as the rewards for which we hope and the punishments which we dread are conceived of as inward and spiritual, we are on safe ground. But such a scheme of rewards and punishments is wholly foreign to the genius of supernaturalism. It is not by becoming more virtuous that we are saved. It is not by becoming more vicious that we are lost. We are saved by obedience, we are lost by disobedience, to the formulated rules of a divinely-delivered law. To appeal to Man's higher self, when there is no higher self to appeal to,--to set before him as the supreme reward of virtue the development of his better nature, when his nature is intrinsically evil,--would be an obvious waste of labour. And as, apart from the presumed repugnance of the "natural man" to the presumed delights of the Law, the intrinsic attractiveness of the life that legalism prescribes must needs diminish in exact proportion as the authority of the Law becomes oppressive and vexatious, and the letter of it tends to establish itself at the expense of the spirit,--it is clear that a scheme of rewards and punishments will become, in effect as well as in theory, the only weapon in the armoury of the legalist. It is also clear that there will be much work for that one weapon to do. The central tendencies of Man's nature, besides being _ex hypothesi_ evil, are antagonistic _de facto_ to the galling despotism and the irrational requirements of the Law; and the lawgiver, far from being able to enlist those tendencies under his banner by appealing to the highest of them--the natural leaders of the rest,--must be prepared to overcome their collective resistance by winning to his side the lowest of them, by terrifying Man's weaker self with threats, by corrupting his baser self with bribes. The ruin of Man's nature, whether hypothetical or actual,[4] has left intact (or relatively intact) only the animal base of it. It is to his animal instincts, then, that legalism must appeal in its endeavour to influence his conduct. In other words, the punishments and the rewards to which Man is to look forward must be of the same _genus_, if not of the same _species_, as the lash of the whip that punishes the lagging race-horse, or the lump of sugar that rewards his exertions. And with the inevitable growth of egoism
