And now observe that though the general conclusion enforced by these special conclusions is at variance with nominally accepted beliefs, it is not at variance with actually accepted beliefs. While opposed to the doctrine which men are taught should be acted upon, it is in harmony with the doctrine which they do act upon and dimly see must be acted upon. For omitting such abnormalities of conduct as are instanced above, every one, alike by deed and word, implies that in the business of life personal welfare is the primary consideration. The laborer looking for wages in return for work done, no less than the merchant who sells goods at a profit, the doctor who expects fees for advice, the priest who calls the scene of his ministrations "a living," assumes as beyond question the truth that selfishness, carried to the extent of enforcing his claims and enjoying the returns his efforts bring, is not only legitimate but essential. Even persons who avow a contrary conviction prove by their acts that it is inoperative. Those who repeat with emphasis the maxim, "Love your neighbor as yourself," do not render up what they possess so as to satisfy the desires of all as much as they satisfy their own desires. Nor do those whose extreme maxim is, "Live for others," differ appreciably from people around in their regards for personal welfare, or fail to appropriate their shares of life's pleasures. In short, that which is above set forth as the belief to which scientific ethics leads us, is that which men do really believe, as distinguished from that which they believe they believe.
Finally, it may be remarked that a rational egoism, so far from implying a more egoistic human nature, is consistent with a human nature that is less egoistic. For excesses in one direction do not prevent excesses in the opposite direction; but rather, extreme deviations from the mean on one side lead to extreme deviations on the other side. A society in which the most exalted principles of self-sacrifice for the benefit of neighbors are enunciated, may be a society in which unscrupulous sacrifice of alien fellow-creatures is not only tolerated but applauded. Along with professed anxiety to spread these exalted principles among heathens, there may go the deliberate fastening of a quarrel upon them with a view to annexing their territory. Men who every Sunday have listened approvingly to injunctions carrying the regard for other men to an impracticable extent, may yet hire themselves out to slay, at the word of command, any people in any part of the world, utterly indifferent to the right or wrong of the matter fought about. And as in these cases transcendent altruism in theory co-exists with brutal egoism in practice, so conversely, a more qualified altruism may have for its concomitant a greatly moderated egoism. For asserting the due claims of self, is, by implication, drawing a limit beyond which the claims are undue; and is, by consequence, bringing into greater clearness the claims of others.
[CHAPTER XII.]
ALTRUISM VERSUS EGOISM.
§ 75. If we define altruism as being all action which, in the normal course of things, benefits others instead of benefiting self, then, from the dawn of life, altruism has been no less essential than egoism. Though, primarily, it is dependent on egoism, yet, secondarily, egoism is dependent on it.
Under altruism, in this comprehensive sense, I take in the acts by which offspring are preserved and the species maintained. Moreover, among these acts must be included not such only as are accompanied by consciousness but also such as conduce to the welfare of offspring without mental representation of the welfare—acts of automatic altruism as we may call them. Nor must there be left out those lowest altruistic acts which subserve race-maintenance without implying even automatic nervous processes—acts not in the remotest sense psychical, but in a literal sense physical. Whatever action, unconscious or conscious, involves expenditure of individual life to the end of increasing life in other individuals, is unquestionably altruistic in a sense, if not in the usual sense, and it is here needful to understand it in this sense that we may see how conscious altruism grows out of unconscious altruism.
The simplest beings habitually multiply by spontaneous fission. Physical altruism of the lowest kind, differentiating from physical egoism, may, in this case, be considered as not yet independent of it. For since the two halves which, before fission, constituted the individual, do not on dividing disappear, we must say that though the individuality of the parent infusorium or other protozoon is lost in ceasing to be single, yet the old individual continues to exist in each of the new individuals. When, however, as happens generally with these smallest animals, an interval of quiescence ends in the breaking up of the whole body into minute parts, each of which is the germ of a young one, we see the parent entirely sacrificed in forming progeny.
Here might be described how among creatures of higher grades, by fission or gemmation, parents bequeath parts of their bodies, more or less organized, to form offspring at the cost of their own individualities. Numerous examples might also be given of the ways in which the development of ova is carried to the extent of making the parental body little more than a receptacle for them: the implication being that the accumulations of nutriment which parental activities have laid up, are disposed of for the benefit of posterity. And then might be dwelt on the multitudinous cases where, as generally throughout the insect-world, maturity having been reached and a new generation provided for, life ends: death follows the sacrifices made for progeny.
But leaving these lower types in which the altruism is physical only, or in which it is physical and automatically psychical only, let us ascend to those in which it is also, to a considerable degree, conscious. Though, in birds and mammals, such parental activities, as are guided by instinct, are accompanied by either no representations or but vague representations of the benefits which the young receive, yet there are also in them actions which we may class as altruistic in the higher sense. The agitation which creatures of these classes show when their young are in danger, joined often with efforts on their behalf, as well as grief displayed after loss of their young, make it manifest that in them parental altruism has a concomitant of emotion.
