This is an interesting rationalization of the facts because in the sense in which “pay” is meant it is so obviously false. Altruism does not at present, and cannot, pay the individual in anything but feeling, as theory declares it must. It is clear, of course, that as long as altruism is regarded as in the nature of a judgment, the fact is overlooked that necessarily its only reward can be in feeling. Man is altruistic because he must be, not because reason recommends it, for herd suggestion opposes any advance in altruism, and when it can the herd executes the altruist, not of course as such but as an innovator. This is a remarkable instance of the protean character of the gregarious instinct and the complexity it introduces into human affairs, for we see one instinct producing manifestations directly hostile to each other—prompting to ever advancing developments of altruism, while it necessarily leads to any new product of advance being attacked. It shows, moreover, as will be pointed out again later, that a gregarious species rapidly developing a complex society can be saved from inextricable confusion only by the appearance of reason and the application of it to life. {47}
When we remember the fearful repressing force which society has always exercised on new forms of altruism and how constantly the dungeon, the scaffold, and the cross have been the reward of the altruist, we are able to get some conception of the force of the instinctive impulse which has triumphantly defied these terrors, and to appreciate in some slight degree how irresistible an enthusiasm it might become if it were encouraged by the unanimous voice of the herd.
In conclusion we have to deal with one more consequence of the social habit in man, a consequence the discussion of which involves some speculation of a necessarily quite tentative kind.
If we look in a broad, general way at the four instincts which bulk largely in man’s life, namely, those of self-preservation, nutrition, sex, and the herd, we shall see at once that there is a striking difference between the
