But to say that each individual shall reap the benefits brought to him by his own powers, inherited and acquired, is to enunciate egoism as an ultimate principle of conduct. It is to say that egoistic claims must take precedence of altruistic claims.
§ 70. Under its biological aspect this proposition cannot be contested by those who agree in the doctrine of Evolution; but probably they will not at once allow that admission of it under its ethical aspect is equally unavoidable. While, as respects development of life, the well-working of the universal principle described is sufficiently manifest; the well-working of it as respects increase of happiness may not be seen at once. But the two cannot be disjoined.
Incapacity of every kind and of whatever degree causes unhappiness directly and indirectly—directly by the pain consequent on the overtaxing of inadequate faculty, and indirectly by the non-fulfillment, or imperfect fulfillment, of certain conditions to welfare. Conversely, capacity of every kind sufficient for the requirement conduces to happiness immediately and remotely—immediately by the pleasure accompanying the normal exercise of each power that is up to its work, and remotely by the pleasures which are furthered by the ends achieved. A creature that is weak or slow of foot, and so gets food only by exhausting efforts, or escapes enemies with difficulty, suffers the pains of over-strained powers, of unsatisfied appetites, of distressed emotions; while the strong and swift creature of the same species delights in its efficient activities, gains more fully the satisfactions yielded by food as well as the renewed vivacity this gives, and has to bear fewer and smaller pains in defending itself against foes or escaping from them. Similarly with duller and keener senses, or higher and lower degrees of sagacity. The mentally-inferior individual of any race suffers negative and positive miseries; while the mentally-superior individual receives negative and positive gratifications. Inevitably, then, this law in conformity with which each member of a species takes the consequences of its own nature; and in virtue of which the progeny of each member, participating in its nature, also takes such consequences; is one that tends ever to raise the aggregate happiness of the species, by furthering the multiplication of the happier and hindering that of the less happy.
All this is true of human beings as of other beings. The conclusion forced on us is that the pursuit of individual happiness within those limits prescribed by social conditions, is the first requisite to the attainment of the greatest general happiness. To see this it needs but to contrast one whose self-regard has maintained bodily well-being, with one whose regardlessness of self has brought its natural results; and then to ask what must be the contrast between two societies formed of two such kinds of individuals.
Bounding out of bed after an unbroken sleep, singing or whistling as he dresses, coming down with beaming face ready to laugh on the smallest provocation, the healthy man of high powers, conscious of past successes and by his energy, quickness, resource, made confident of the future, enters on the day's business not with repugnance, but with gladness; and from hour to hour experiencing satisfactions from work effectually done, comes home with an abundant surplus of energy remaining for hours of relaxation. Far otherwise is it with one who is enfeebled by great neglect of self. Already deficient, his energies are made more deficient by constant endeavors to execute tasks that prove beyond his strength, and by the resulting discouragement. Besides the depressing consciousness of the immediate future, there is the depressing consciousness of the remoter future, with its probability of accumulated difficulties and diminished ability to meet them. Hours of leisure which, rightly passed, bring pleasures that raise the tide of life and renew the powers of work, cannot be utilized: there is not vigor enough for enjoyments involving action, and lack of spirits prevents passive enjoyments from being entered upon with zest. In brief, life becomes a burden. Now if, as must be admitted, in a community composed of individuals like the first, the happiness will be relatively great, while in one composed of individuals like the last, there will be relatively little happiness, or rather much misery; it must be admitted that conduct causing the one result is good, and conduct causing the other is bad.
But diminutions of general happiness are produced by inadequate egoism in several other ways. These we will successively glance at.
§ 71. If there were no proofs of heredity—if it were the rule that the strong are usually begotten by the weak, while the weak usually descend from the strong, that vivacious children form the families of melancholy parents, while fathers and mothers with overflowing spirits mostly have dull progeny, that from stolid peasants there ordinarily come sons of high intelligence while the sons of the cultured are commonly fit for nothing but following the plow—if there were no transmission of gout, scrofula, insanity, and did the diseased habitually give birth to the healthy and the healthy to the diseased, writers on Ethics might be justified in ignoring those effects of conduct which are felt by posterity through the natures they inherit.
As it is, however, the current ideas concerning the relative claims of egoism and altruism are vitiated by the omission of this all all-important factor. For if health, strength and capacity, are usually transmitted; and if disease, feebleness, stupidity, generally reappear in descendants; then a rational altruism requires insistance on that egoism which is shown by receipt of the satisfactions accompanying preservation of body and mind in the best state. The necessary implication is that blessings are provided for offspring by due self-regard, while disregard of self carried too far provides curses. When, indeed, we remember how commonly it is remarked that high health and overflowing spirits render any lot in life tolerable, while chronic ailments make gloomy a life most favorably circumstanced, it becomes amazing that both the world at large and writers who make conduct their study, should ignore the terrible evils which disregard of personal well-being inflicts on the unborn, and the incalculable good laid up for the unborn by attention to personal well-being. Of all bequests of parents to children the most valuable is a sound constitution. Though a man's body is not a property that can be inherited, yet his constitution may fitly be compared to an entailed estate; and if he rightly understands his duty to posterity, he will see that he is bound to pass on that estate uninjured if not improved. To say this is to say that he must be egoistic to the extent of satisfying all those desires associated with the due performance of functions. Nay, it is to say more. It is to say that he must seek in due amounts the various pleasures which life offers. For beyond the effect these have in raising the tide of life and maintaining constitutional vigor, there is the effect they have in preserving and increasing a capacity for receiving enjoyment. Endowed with abundant energies and various tastes, some can get gratifications of many kinds on opportunities hourly occurring; while others are so inert, and so uninterested in things around, that they cannot even take the trouble to amuse themselves. And unless heredity be denied, the inference must be that due acceptance of the miscellaneous pleasures life offers, conduces to the capacity for enjoyment in posterity; and that persistence in dull monotonous lives by parents, diminishes the ability of their descendants to make the best of what gratifications fall to them.
§ 72. Beyond the decrease of general happiness which results in this indirect way, if egoism is unduly subordinated, there is a decrease of general happiness which results in a direct way. He who carries self-regard far enough to keep himself in good health and high spirits, in the first place, thereby becomes an immediate source of happiness to those around, and, in the second place, maintains the ability to increase their happiness by altruistic actions. But one whose bodily vigor and mental health are undermined by self-sacrifice carried too far, in the first place becomes to those around a cause of depression, and, in the second place, renders himself incapable, or less capable, of actively furthering their welfare.
In estimating conduct we must remember that there are those who by their joyousness beget joy in others, and that there are those who by their melancholy cast a gloom on every circle they enter. And we must remember that by display of overflowing happiness a man of the one kind may add to the happiness of others more than by positive efforts to benefit them, and that a man of the other kind may decrease their happiness more by his presence than he increases it by his actions. Full of vivacity the one is ever welcome. For his wife he has smiles and jocose speeches; for his children stores of fun and play; for his friends pleasant talk interspersed with the sallies of wit that come from buoyancy. Contrariwise, the other is shunned. The irritability resulting now from ailments, now from failures caused by feebleness, his family has daily to bear. Lacking adequate energy for joining in them, he has at best but a tepid interest in the amusements of his children, and he is called a wet blanket by his friends. Little account as our ethical reasonings take note of it, yet is the fact obvious that since happiness and misery are infectious, such regard for self as conduces to health and high spirits is a benefaction to others, and such disregard of self as brings on suffering, bodily or mental, is a malefaction to others.
