Morals and the Evolution of Man

In this survey of the immense field of literature dealing with moral philosophy we have learnt that, although the most various and divergent views are expressed as to the essence and source of Morality, nevertheless there is but one opinion, be it clearly or vaguely stated, be it the result of knowledge or surmise, as to the mechanism by means of which moral concepts determine action, and as to the conscious or unconscious aim of moral action: Moral concepts do their work by means of inhibition, and the aim of moral action is a feeling of happiness.
