To realize the monstrosity of this doctrine of twofold Morality, public and private, and of the non-compulsoriness of moral law for the state, it suffices to refer again to the fundamental concepts of Morality. Individuals have banded themselves together in a community in order to be able to live more easily, or to live at all, under the present conditions obtaining on our planet. Lest society should be disintegrated by the quarrels of its members, and the latter should find themselves exposed single-handed to a hopeless struggle for existence, a limitation of their unfettered whims and desires, the curbing of their selfishness, control of their impulses and the exercise of consideration for their neighbours have been imposed upon them. This coercion is Morality, and society can enforce it by vigorous measures; but for the most part this is unnecessary, for society has inculcated in its members the faculty of urging upon themselves in every situation the dictates of the community and of insisting on obedience to them. This faculty is conscience. The means by which conscience, inspired and assisted by reason, determines the will to keep in check or to suppress organic impulses and inclinations, desires and appetites, is inhibition; moreover, the development and strengthening of inhibition does not alone promote the aims of the community, but is of the highest biological importance to the individual himself, apart from his relations to society, as it renders him stronger and more efficient, differentiates him more subtly, and raises him to a higher level of development.
