The ethical law, from the standpoint of Individualism, is expressed by a formula which requires harmonious relation between the interest of the life as totality and the impulse of the moment; it consists of two chief mandates: (1) The single instant should have no greater independence than corresponds to its significance in the life as totality; (2) but, on the other hand, the single moments should be as richly and intensely lived as is consistent with the preservation of the life's totality. Of Individualism, or the principle of the Sovereignty of the Individual, the same is true as of the sovereignty of the moment, that no reasoning can overthrow it; if the individual recognizes no end but his own life, there is no logical way of transition to another standpoint. A change of aim can take place only through such a change in the central feelings which determine the standard of the individual that a wider circle of conceptions enter into his reflections. Until this takes place, there is no use in appealing to conscience. The science of Ethics has often claimed to be a science of pure reason. This claim is opposed to its character as a practical science, since action can be judged only according to the ends it had in view, and ends presuppose feelings of pain and pleasure. On the other hand, there is, in the mere capacity for pain and pleasure, no limitation of the extent of the circle of conceptions with which the feelings of pain and pleasure are connected. Individualism can be carried out in practice only approximately; the individual has his origin in the species, and lives his whole life as a part of the life of his kind, with an organization in which the results of the action and passion of earlier generations are inherited, and in a mental atmosphere which has induced the development of his species. And just as the instinct of self-preservation did away with the isolation of the single moments of the individual life, becoming, thus, the basis of feelings determined by the interests of the life as totality, so the sympathetic instincts do away with the isolation of the single individuals and determine the conditions of the life of the species in the minds of its individuals. The most primitive form of the sympathetic instincts is exhibited in the family. Here, however loose and variable the relation of man and wife may be, that of mother and child cannot, by its nature, be done away with or essentially changed. In this case, the sympathetic feeling springs immediately from the natural instinct, and the relation is the nucleus which makes possible the higher forms of family life. In the family circle, the sympathetic feelings are cultivated, and arrive at such strength that they come to include ever wider and wider circles of human beings. Indeed, the mother-love remains forever the image and criterion of all sympathy, as well in respect to strength as to purity.
