That the range of æsthetic gratifications is wider for the altruistic nature than for the egoistic nature is also a truth not to be overlooked. The joys and sorrows of human beings form a chief element in the subject-matter of art, and, evidently, the pleasures which art gives increase as the fellow-feeling with these joys and sorrows strengthens. If we contrast early poetry occupied mainly with war and gratifying the savage instincts by descriptions of bloody victories, with the poetry of modern times, in which the sanguinary forms but a small part while a large part, dealing with the gentler affections, enlists the feelings of readers on behalf of the weak; we are shown that with the development of a more altruistic nature there has been opened a sphere of enjoyment inaccessible to the callous egoism of barbarous times. So, too, between the fiction of the past and the fiction of the present, there is the difference that while the one was almost exclusively occupied with the doings of the ruling classes, and found its plots in their antagonisms and deeds of violence, the other, chiefly taking stories of peaceful life for its subjects, and to a considerable extent the life of the humbler classes, discloses a new world of interest in the every-day pleasures and pains of ordinary people. A like contrast exists between early and late forms of plastic art. When not representing acts of worship, the wall sculptures and wall-paintings of the Assyrians and Egyptians, or the decorations of temples among the Greeks, represented deeds of conquest; whereas in modern times, while the works which glorify destructive activities are less numerous, there are an increasing number of works gratifying to the kindlier sentiments of spectators. To see that those who care nothing about the feelings of other beings are, by implication, shut out from a wide range of æsthetic pleasures, it needs but to ask whether men who delight in dog-fights may be expected to appreciate Beethoven's Adelaida, or whether Tennyson's In Memoriam would greatly move a gang of convicts.
§ 81. From the dawn of life, then, egoism has been dependent upon altruism as altruism has been dependent upon egoism, and in the course of evolution the reciprocal services of the two have been increasing.
The physical and unconscious self-sacrifice of parents to form offspring, which the lowest living things display from hour to hour, shows us in its primitive form the altruism which makes possible the egoism of individual life and growth. As we ascend to higher grades of creatures, this parental altruism becomes a direct yielding up of only part of the body, joined with an increasing contribution from the remainder in the shape of tissue wasted in efforts made on behalf of progeny. This indirect sacrifice of substance, replacing more and more the direct sacrifice as parental altruism becomes higher, continues to the last to represent also altruism which is other than parental; since this, too, implies loss of substance in making efforts that do not bring their return in personal aggrandizement.
After noting how among mankind parental altruism and family altruism pass into social altruism, we observed that a society, like a species, survives only on condition that each generation of its members shall yield to the next, benefits equivalent to those it has received from the last. And this implies that care for the family must be supplemented by care for the society.
Fullness of egoistic satisfactions in the associated state, depending primarily on maintenance of the normal relation between efforts expended and benefits obtained, which underlies all life, implies an altruism which both prompts equitable conduct and prompts the enforcing of equity. The well-being of each is involved with the well-being of all in sundry other ways. Whatever conduces to their vigor concerns him, for it diminishes the cost of everything he buys. Whatever conduces to their freedom from disease concerns him, for it diminishes his own liability to disease. Whatever raises their intelligence concerns him, for inconveniences are daily entailed on him by others' ignorance or folly. Whatever raises their moral character concerns him, for at every turn he suffers from the average unconscientiousness.
Much more directly do his egoistic satisfactions depend on those altruistic activities which enlist the sympathies of others. By alienating those around, selfishness loses the unbought aid they can render; shuts out a wide range of social enjoyments, and fails to receive those exaltations of pleasure and mitigations of pain which come from men's fellow-feeling with those they like.
Lastly, undue egoism defeats itself by bringing on an incapacity for happiness. Purely egoistic gratifications are rendered less keen by satiety, even in the earlier part of life, and almost disappear in the later; the less satiating gratifications of altruism are missed throughout life, and especially in that latter part when they largely replace egoistic gratifications; and there is a lack of susceptibility to æsthetic pleasures of the higher orders.
An indication must be added of the truth, scarcely at all recognized, that this dependence of egoism upon altruism ranges beyond the limits of each society, and tends ever toward universality. That within each society it becomes greater as social evolution, implying increase of mutual dependence, progresses, needs not be shown; and it is a corollary that as fast as dependence of societies on one another is increased by commercial intercourse, the internal welfare of each becomes a matter of concern to the others. That the impoverishment of any country, diminishing both its producing and consuming powers, tells detrimentally on the people of countries trading with it, is a commonplace of political economy. Moreover, we have had of late years, abundant experience of the industrial derangements through which distress is brought on nations not immediately concerned by wars between other nations. And if each community has the egoistic satisfactions of its members diminished by aggressions of neighboring communities on one another, still more does it have them diminished by its own aggressions. One who marks how, in various parts of the world, the unscrupulous greed of conquest cloaked by pretences of spreading the blessings of British rule and British religion, is now reacting to the immense detriment of the industrial classes at home, alike by increasing expenditure and paralyzing trade, may see that these industrial classes, absorbed in questions about capital and labor, and thinking themselves unconcerned in our doings abroad, are suffering from lack of that wide-reaching altruism which should insist on just dealings with other peoples, civilized or savage. And he may also see that beyond these immediate evils, they will for a generation to come suffer the evils that must flow from resuscitating the type of social organization which aggressive activities produce, and from the lowered moral tone which is its accompaniment.
