_The Principle not invalidated by the Fact that Forethought is often Weak._--All the motives for saving may be unduly weak. The man may care far less for the future than he should do, and may make an unreasonably small provision for it. Incapacity to estimate the importance of this provision, as well as the degree of selfishness which excludes the exercise of self-denial for the benefit of others, are not the only reasons for this disregard of the future. There is an optimism which is natural; and a religious faith which bids one not to take unduly anxious thought for the morrow may occasionally be carried to the harmful length of justifying a neglect of coming years and their needs. An intelligent trust in Providence, however, incites a man to do his own full duty, and it is the better men who do the most to avert future evils from their families. The principle that we are maintaining applies as completely in the cases of those who make small provision for the future as it does in any others. In the majority of cases whatever they do save is set aside chiefly for the maintenance of some standard of living by those who get the benefit of it; and to maintain any standard whatever, whether high or low, requires a larger fortune when interest is low than it does when interest is high. _Forethought limited in the Length of Time it Covers._--There is little danger that we make any mistake in ascribing to the dread of falling below a standard of living more influence on the accumulation of capital than any other motive exerts. This will be clearer if we look at the actual manner in which present and future are estimated and compared. The fact is not that most people care unduly little for all future benefits as compared with present ones, as it is that they throw off responsibility for all the future beyond a limited period. The perspective does not reduce the size of remote objects unduly as often as it cuts off the view of them altogether. In looking through coming years a man is subject to a certain economic myopia. One might compare what he sees with what a man sees in a foggy atmosphere, if it were not for the fact that the view of comparatively near objects is clear. It is as though a circle of fog surrounded him and cut off somewhat abruptly the view of everything that was far away. For a short distance the man sees everything with comparative clearness, but the limitless spaces that lie beyond he sees not at all. We have seen that the amount of abstinence he will practice now for the sake of what he or others will gain later varies as he is rational or foolish, unselfish or selfish, and it is also true that the length of his outlook into the future varies in the same way. There are all gradations of far-sightedness among those who create capital; but even comparatively near-sighted ones usually provide for the maintenance of some standard or other during the period that falls within their range
