When sympathy has reached full purity, it is a feeling of pain or pleasure determined by the fact that other beings feel pain or pleasure. The most important point of its development was when it so broadened as to include all mankind. The Peripatetic and the Stoic schools of Greek philosophy led to this idea of love to all humanity and the natural union of all men in one great society. But this idea acquired greater historic importance when it became a chief commandment of a great religion,--of Christianity. To this sympathetic feeling the criterion of good and evil is no longer to be found in the individual life, but is dependent on the life of the whole society of which the individual is a member. Yet sympathy is not, from this standpoint, identical with the ethical feeling, conscience. Conscience is here, too, a feeling of relations determined by the relation between the ruling or central feeling of the individual and the results of action. When the individual feels his own interests subordinate to the good of the whole of which, through sympathy, he regards himself as a part, the ethical feeling appears as the feeling of duty. A feeling of duty may be spoken of, likewise, from the standpoint of pure Individualism, for the concept of duty expresses only the relation of a lower, narrower consideration to a higher; and this is represented, in Individualism, by the relation of the single moments to the life as a whole. From another point of view, the ethical feeling appears, in its higher development, as the feeling of justice, which, while regarding the good of the whole as the chief end, considers also the peculiarities of individuals. Sympathy in its active form is impulse to share. This sharing must be carried out according to fixed principles; where sympathy is universal, differences of division can be justified only by the fact that the Goods divided, if otherwise divided, would not be in so high a degree Goods to those to whom they reverted, or would not conduce to so great progress of the society as a whole. The ethical law upon this standpoint, the standpoint of Humane Ethics, can be no other as to content, than that action shall conduce to the greatest possible welfare and the greatest possible progress of the greatest possible number of conscious beings; and this law includes two chief mandates, a negative and a positive mandate: (1) The individual may not receive more than befits the position which, in consequence of his peculiar qualities, he occupies among his kind; (2) but, on the other hand, the capacities and impulses of every individual shall be as fully and richly developed and satisfied as is consistent with the demands of the life of the species as a whole. These two mandates follow with logical necessity from the concept of society as a multiplicity of conscious beings united into one whole. It is contrary to the unity of society, that an individual, or that individuals, should be wilfully preferred to
