Feuerbach expresses this thought clearly and distinctly when he says: "There can be no question of Morality in the strict sense of the word except where the subject of discussion is the relationship of man to man, of one person to another, of me to thee." Recent contemporary French writers are in no way doubtful of the meaning implied by the concept of Morality. "Morality," says Littré, "is the whole collection of rules which determine our conduct towards others. Moral Good is the ideal, which at any period of a civilization forms opinions and customs with respect to this conduct; moral evil is that which offends this ideal." This definition is very incomplete and weak, as will be seen in the course of our remarks, but on one point it is quite clear: it treats Morality as a social phenomenon, it paraphrases it as the adjustment of individual action to the standard set up by the community. The question of the origin and the aim of this standard is left open. L. Lévy-Brühl formulates Littré's idea more clearly. "We call by the name of Morality the collection of such conceptions, opinions, feelings and customs respecting the mutual rights and duties of men in their life as members of a community, as are recognized and generally observed at a given time in a given civilization." Thus, according to some, Morality is subjection to an absolute law of divine, or at any rate of unexplained and inexplicable origin, which religion or a mysterious inner voice reveals to man; according to others, it is the recognition that the claims of the community, or at any rate of the majority of one's fellow men, are of binding force upon the actions of the individual. These different answers to an inquiry as to the origin of Morality both contain the tacit admission that it is a law which peremptorily dictates to man what he shall do and what he shall not do. But by means of what psychic mechanism does this law enforce obedience in the consciousness of man? It is remarkable that all moral philosophers, no matter to what age, nation or school they belong, dimly feel or clearly recognize that in civilized man at any rate, natural instincts and judgment are always at war; that the latter opposes the former; that in the victory of judgment over impulse lies the very essence of Morality; that consequently the essence of Morality implies the control and repression of instinct by Reason--in a word, that it is inhibition. We have seen that Aristotle, in definite though unconscious opposition to the Stoics, who consider Morality synonymous with Nature, defines it as the activity of Reason. Henry More was the first to express this quite clearly: "Virtue is an intellectual force of the soul which enables it to control ... animal instincts and sensual passions."
