These diffused physiological effects of pleasures and pains, which are joined with the local or special physiological effects, are, indeed, obviously inevitable. We have seen (Principles of Psychology, §§ 123–125) that while craving, or negative pain, accompanies the under-activity of an organ, and while positive pain accompanies its over-activity, pleasure accompanies its normal activity. We have seen that by evolution no other relations could be established; since, through all inferior types of creatures, if defect or excess of function produced no disagreeable sentiency, and medium function no agreeable sentiency, there would be nothing to insure a proportioned performance of function. And as it is one of the laws of nervous action that each stimulus, beyond a direct discharge to the particular organ acted on, indirectly causes a general discharge throughout the nervous system (Prin. of Psy., §§ 21, 39), it results that the rest of the organs, all influenced as they are by the nervous system, participate in the stimulation. So that beyond the aid, more slowly shown, which the organs yield to one another through the physiological division of labor, there is the aid, more quickly shown, which mutual excitation gives. While there is a benefit to be presently felt by the whole organism from the due performance of each function, there is an immediate benefit from the exaltation of its functions at large caused by the accompanying pleasure; and from pains, whether of excess or defect, there also come these double effects, immediate and remote.
§ 37. Non-recognition of these general truths vitiates moral speculation at large. From the estimates of right and wrong habitually framed, these physiological effects wrought on the actor by his feelings are entirely omitted. It is tacitly assumed that pleasures and pains have no reactions on the body of the recipient, affecting his fitness for the duties of life. The only reactions recognized are those on character; respecting which the current supposition is, that acceptance of pleasures is detrimental and submission to pains beneficial. The notion, remotely descended from the ghost-theory of the savage, that mind and body are independent, has, among its various implications, this belief that states of consciousness are in no wise related to bodily states. "You have had your gratification—it is past; and you are as you were before," says the moralist to one. And to another he says, "You have borne the suffering—it is over; and there the matter ends." Both statements are false. Leaving out of view indirect results, the direct results are that the one has moved a step away from death and the other has moved a step toward death.
Leaving out of view, I say, the indirect results. It is these indirect results, here for the moment left out of view, which the moralist has exclusively in view, being so occupied by them that he ignores the direct results. The gratification, perhaps purchased at undue cost, perhaps enjoyed when work should have been done, perhaps snatched from the rightful claimant, is considered only in relation to remote injurious effects, and no set-off is made for immediate beneficial effects. Conversely, from positive and negative pains, borne now in the pursuit of some future advantage, now in discharge of responsibilities, now in performing a generous act, the distant good is alone dwelt on and the proximate evil ignored. Consequences, pleasurable and painful, experienced by the actor forthwith, are of no importance; and they become of importance only when anticipated as occurring hereafter to the actor or to other persons. And further, future evils borne by the actor are considered of no account if they result from self-denial, and are emphasized only when they result from self-gratification. Obviously, estimates so framed are erroneous; and obviously, the pervading judgments of conduct based on such estimates must be distorted. Mark the anomalies of opinion produced.
If, as the sequence of a malady contracted in pursuit of illegitimate gratification, an attack of iritis injures vision, the mischief is to be counted among those entailed by immoral conduct; but if, regardless of protesting sensations, the eyes are used in study too soon after ophthalmia, and there follows blindness for years or for life, entailing not only personal unhappiness, but a burden on others, moralists are silent. The broken leg which a drunkard's accident causes counts among those miseries brought on self and family by intemperance, which form the ground for reprobating it; but if anxiety to fulfill duties prompts the continued use of a sprained knee spite of the pain, and brings on a chronic lameness involving lack of exercise, consequent ill-health, inefficiency, anxiety, and unhappiness, it is supposed that ethics has no verdict to give in the matter. A student who is plucked because he has spent in amusement the time and money that should have gone in study, is blamed for thus making parents unhappy and preparing for himself a miserable future; but another who, thinking exclusively of claims on him, reads night after night with hot or aching head, and, breaking down, cannot take his degree, but returns home shattered in health and unable to support himself, is named with pity only, as not subject to any moral judgment; or rather, the moral judgment passed is wholly favorable.
Thus recognizing the evils caused by some kinds of conduct only, men at large, and moralists as exponents of their beliefs, ignore the suffering and death daily caused around them by disregard of that guidance which has established itself in the course of evolution. Led by the tacit assumption common to Pagan stoics and Christian ascetics, that we are so diabolically organized that pleasures are injurious and pains beneficial, people on all sides yield examples of lives blasted by persisting in actions against which their sensations rebel. Here is one who, drenched to the skin and sitting in a cold wind, pooh-hoohs his shiverings and gets rheumatic fever, with subsequent heart-disease, which makes worthless the short life remaining to him. Here is another who, disregarding painful feelings, works too soon after a debilitating illness, and establishes disordered health that lasts for the rest of his days, and makes him useless to himself and others. Now the account is of a youth who, persisting in gymnastic feats spite of scarcely bearable straining, bursts a blood-vessel, and, long laid on the shelf, is permanently damaged; while now it is of a man in middle life who, pushing muscular effort to painful excess, suddenly brings on hernia. In this family is a case of aphasia, spreading paralysis and death, caused by eating too little and doing too much; in that, softening of the brain has been brought on by ceaseless mental efforts against which the feelings hourly protested; and in others, less serious brain affections have been contracted by over-study continued regardless of discomfort and the cravings for fresh air and exercise.[B] Even without accumulating special examples, the truth is forced on us by the visible traits of classes. The careworn man of business too long at his office, the cadaverous barrister pouring half the night over his briefs, the feeble factory hands and unhealthy seamstresses passing long hours in bad air, the anæmic, flat-chested school-girls, bending over many lessons and forbidden boisterous play, no less than Sheffield grinders who die of suffocating dust, and peasants crippled with rheumatism due to exposure, show us the wide spread miseries caused by persevering in actions repugnant to the sensations and neglecting actions which the sensations prompt. Nay, the evidence is still more extensive and conspicuous. What are the puny malformed children, seen in poverty-stricken districts, but children whose appetites for food and desires for warmth have not been adequately satisfied? What are populations stinted in growth and prematurely aged, such as parts of France show us, but populations injured by work in excess and food in defect: the one implying positive pain, the other negative pain? What is the implication of that greater mortality which occurs among people who are weakened by privations, unless it is that bodily miseries conduce to fatal illnesses? Or once more, what must we infer from the frightful amount of disease and death suffered by armies in the field, fed on scanty and bad provisions, lying on damp ground, exposed to extremes of heat and cold, inadequately sheltered from rain, and subject to exhausting efforts; unless it be the terrible mischiefs caused by continuously subjecting the body to treatment which the feelings protest against?
It matters not to the argument whether the actions entailing such effects are voluntary or involuntary. It matters not from the biological point of view whether the motives prompting them are high or low. The vital functions accept no apologies on the ground that neglect of them was unavoidable, or that the reason for neglect was noble. The direct and indirect sufferings caused by non-conformity to the laws of life are the same whatever induces the non-conformity; and cannot be omitted in any rational estimate of conduct. If the purpose of ethical inquiry is to establish rules of right living; and if the rules of right living are those of which the total results, individual and general, direct and indirect, are most conducive to human happiness; then it is absurd to ignore the immediate results and recognize only the remote results.
§ 38. Here might be urged the necessity for preluding the study of moral science by the study of biological science. Here might be dwelt on the error men make in thinking they can understand those special phenomena of human life with which Ethics deals, while paying little or no attention to the general phenomena of human life, and while utterly ignoring the phenomena of life at large. And, doubtless, there would be truth in the inference that such acquaintance with the world of living things, as discloses the part which pleasures and pains have played in organic evolution, would help to rectify these one-sided conceptions of moralists. It cannot be held, however, that lack of this knowledge is the sole cause, or the main cause, of their one-sidedness. For facts of the kind above instanced, which, duly attended to, would prevent such distortions of moral theory, are facts which it needs no biological inquiries to learn, but which are daily thrust before the eyes of all. The truth is, rather, that the general consciousness is so possessed by sentiments and ideas at variance with the conclusions necessitated by familiar evidence that the evidence gets no attention. These adverse sentiments and ideas have several roots.
There is the theological root. As before shown, from the worship of cannibal ancestors who delighted in witnessing tortures, there resulted the primitive conception of deities who were propitiated by the bearing of pains, and, consequently, angered by the receipt of pleasures. Through the religions of the semi-civilized, in which this conception of the divine nature remains conspicuous, it has persisted, in progressively modified forms, down to our own times; and still colors the beliefs, both of those who adhere to the current creed and of those who nominally reject it.
There is another root in the primitive and still-surviving militancy. While social antagonisms continue to generate war, which consists in endeavors to inflict pain and death while submitting to the risks of pain and death, and which necessarily involves great privations, it is needful that physical suffering, whether considered in itself or in the evils it bequeaths, should be thought little of, and that among pleasures recognized as most worthy should be those which victory brings.
Nor does partially developed industrialism fail to furnish a root. With social evolution, which implies transition from the life of wandering hunters to the life of settled peoples engaged in labor, and which therefore entails activities widely unlike those to which the aboriginal constitution is adapted, there comes an under-exercise of faculties for which the social state affords no scope, and an overtaxing of faculties required for the social state; the one implying denial of certain pleasures and the other submission to certain pains. Hence, along with that growth of population which makes the struggle for existence intense, bearing of pains and sacrifice of pleasures is daily necessitated.
