The private interests of the individual are on the average better subserved, not only in proportion as he himself refrains from direct aggression, but also, on the average, in proportion as he succeeds in diminishing the aggressions of his fellows on one another. The prevalence of antagonism among those around, impedes the activities carried on by each in pursuit of satisfactions; and by causing disorder makes the beneficial results of activities more doubtful. Hence, each profits egoistically from the growth of an altruism which leads each to aid in preventing or diminishing others' violence.
The like holds when we pass to that altruism which restrains the undue egoism displayed in breaches of contract. General acceptance of the maxim that honesty is the best policy, implies general experience that gratification of the self-regarding feelings is eventually furthered by such checking of them as maintains equitable dealings. And here, as before, each is personally interested in securing good treatment of his fellows by one another. For in countless ways evils are entailed on each by the prevalence of fraudulent transactions. As every one knows, the larger the number of a shop-keeper's bills left unpaid by some customers, the higher must be the prices which other customers pay. The more manufacturers lose by defective raw materials or by carelessness of workmen, the more must they charge for their fabrics to buyers. The less trustworthy people are, the higher rises the rate of interest, the larger becomes the amount of capital hoarded, the greater are the impediments to industry. The further traders and people in general go beyond their means, and hypothecate the property of others in speculation, the more serious are those commercial panics which brings disasters on multitudes and injuriously affect all.
This introduces us to yet a third way in which such personal welfare as results from the proportioning of benefits gained to labors given, depends on the making of certain sacrifices for social welfare. The man who, expending his energies wholly on private affairs refuses to take trouble about public affairs, pluming himself on his wisdom in minding his own business, is blind to the fact that his own business is made possible only by maintenance of a healthy social state, and that he loses all round by defective governmental arrangements. Where there are many like-minded with himself—where, as a consequence, offices come to be filled by political adventurers and opinion is swayed by demagogues—where bribery vitiates the administration of the law and makes fraudulent State transactions habitual, heavy penalties fall on the community at large, and, among others, on those who have thus done everything for self and nothing for society. Their investments are insecure; recovery of their debts is difficult, and even their lives are less safe than they would otherwise have been.
So that on such altruistic actions as are implied, firstly in being just, secondly in seeing justice done between others, and thirdly, in upholding and improving the agencies by which justice is administered, depend, in large measure, the egoistic satisfactions of each.
§ 78. But the identification of personal advantage with the advantage of fellow-citizens is much wider than this. In various other ways the well-being of each rises and falls with the well-being of all.
A weak man left to provide for his own wants, suffers by getting smaller amounts of food and other necessaries than he might get were he stronger. In a community formed of weak men, who divide their labors and exchange the products, all suffer evils from the weakness of their fellows. The quantity of each kind of product is made deficient by the deficiency of laboring power; and the share each gets for such share of his own product as he can afford to give, is relatively small. Just as the maintenance of paupers, hospital patients, inmates of asylums, and others who consume but do not produce, leaves to be divided among producers a smaller stock of commodities than would exist were there no incapables; so must there be left a smaller stock of commodities to be divided, the greater the number of inefficient producers, or the greater the average deficiency of producing power. Hence, whatever decreases the strength of men in general restricts the gratifications of each by making the means to them dearer.
More directly, and more obviously, does the bodily well-being of his fellows concern him; for their bodily ill-being, when it takes certain shapes, is apt to bring similar bodily ill-being on him. If he is not himself attacked by cholera, or small-pox, or typhus, when it invades his neighborhood, he often suffers a penalty through his belongings. Under conditions spreading it, his wife catches diphtheria, or his servant is laid up with scarlet fever, or his children take now this and now that infectious disorder. Add together the immediate and remote evils brought on him year after year by epidemics, and it becomes manifest that his egoistic satisfactions are greatly furthered by such altruistic activities as render disease less prevalent.
With the mental, as well as with the bodily, states of fellow-citizens, his enjoyments are in multitudinous ways bound up. Stupidity like weakness raises the cost of commodities. Where farming is unimproved, the prices of food are higher than they would else be; where antiquated routine maintains itself in trade, the needless expense of distribution weighs on all; where there is no inventiveness, every one loses the benefits which improved appliances diffuse. Other than economic evils come from the average unintelligence—periodically through the manias and panics that arise because traders rush in herds all to buy or all to sell; and habitually through the mal-administration of justice, which people and rulers alike disregard while pursuing this or that legislative will-o'-the-wisp. Closer and clearer is the dependence of his personal satisfactions on others' mental states, which each experiences in his household. Unpunctuality and want of system are perpetual sources of annoyance. The unskillfulness of the cook causes frequent vexation and occasional indigestion. Lack of forethought in the housemaid leads to a fall over a bucket in a dark passage. And inattention to a message or forgetfulness in delivering it, entails failure in an important engagement. Each, therefore, benefits egoistically by such altruism as aids in raising the average intelligence. I do not mean such altruism as taxes ratepayers that children's minds may be filled with dates, and names, and gossip about kings, and narratives of battles, and other useless information, no amount of which will make them capable workers or good citizens; but I mean such altruism as helps to spread a knowledge of the nature of things and to cultivate the power of applying that knowledge.
Yet again, each has a private interest in public morals and profits by improving them. Not in large ways only, by aggressions and breaches of contract, by adulterations and short measures, does each suffer from the general unconscientiousness; but in more numerous small ways. Now it is through the untruthfulness of one who gives a good character to a bad servant; now it is by the recklessness of a laundress who, using bleaching agents to save trouble in washing, destroys his linen; now it is by the acted falsehood of railway passengers who, by dispersed coats, make him believe that all the seats in a compartment are taken when they are not. Yesterday the illness of his child due to foul gases, led to the discovery of a drain that had become choked because it was ill-made by a dishonest builder under supervision of a careless or bribed surveyor. To-day workmen employed to rectify it bring on him cost and inconvenience by dawdling; and their low standard of work, determined by the unionist principle that the better workers must not discredit the worse by exceeding them in efficiency, he may trace to the immoral belief that the unworthy should fare as well as the worthy. To-morrow it turns out that business for the plumber has been provided by damage which the bricklayers have done.
Thus the improvement of others, physically, intellectually and morally, personally concerns each; since their imperfections tell in raising the cost of all the commodities he buys, in increasing the taxes and rates he pays, and in the losses of time, trouble and money, daily brought on by others' carelessness, stupidity, or unconscientiousness.
