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
