In the savage, or rather in man at a low stage of civilization, the power of inhibition is far from having reached such perfect development. It is not very robust, works defectively and often fails. Little civilized man, if he has a conscience, cannot even with the best intentions always obey it punctually. His instinct is stronger than his insight. He is not master of his impulses; rather it is they that master him. All who have described tribes of low civilization have observed that their reactions resemble reflex movements and that they lack self-control. Moral conduct, that is, control of their selfishness and consideration for their fellow men, is difficult for them if it demands effort, sacrifice and painful renunciation. However, we need not trouble to go to the negroes of the Congo or the inhabitants of the Solomon Islands to observe the inefficiency of the power of inhibition. We need only look around us. We shall find enough instances among ourselves. The uneducated, the badly educated and abnormal people on whom teaching and example make no impression cannot follow the precepts of Morality, although they know them. To express it as the Roman poet does, they know the better and approve it, but they have a longing for the worse. So it is wrong to say that a savage can be just as virtuous as a Socrates or an Aristides. He could not, even if he would. He would lack the organic means: a sufficiently trained intelligence to point out his moral duty, a sufficiently developed faculty of inhibition to follow the admonition of his intelligence. Bouillier's objection to moral progress will not hold water. The Romantics who have invented the fairy tale of the noble savage and who declare in Seume's words: "See, we savages are better men after all," are out of touch with reality. Like civilization, and simultaneously with civilization, Morality progresses towards improvement, towards perfection. The Kantian moralist, like the theologian, is forbidden by the logic of his system to admit the possibility of moral progress. If the moral law is categorical, that is, unlimited by any special purpose, if it exists within us, eternal and immutable as the stars above us, we should be hard put to it to say how this unalterable block, placed in our souls we know not how or by whom, could receive an impetus to progressive development, or in what way this development could be carried out. That which is categorical is absolute, and the concept of progress in the absolute, as in the infinite and the eternal, has no sense. But whoever regards Morality from the biological and sociological point of view is forced to assert its progress, just as the dogmatic mystic, who believes in the categorical imperative, is forced to deny it.
