With regard to the first of those qualities, it has been observed on a former occasion, that superior reason and understanding are originally approved of as just and right and accurate, and not merely as useful or advantageous. It is in the abstruser sciences, particularly in the higher parts of mathematics, that the greatest and most admired exertions of human reason have been displayed. But the utility of those sciences, either to the individual or to the public, is not very obvious, and to prove it, requires a discussion which is not always very easily comprehended. It was not, therefore, their utility which first recommended them to the public admiration. This quality was but little insisted upon, till it became necessary to make some reply to the reproaches of those, who, having themselves no taste for such sublime discoveries, endeavoured to depreciate them as useless. That self-command, in the same manner, by which we restrain our present appetites, in order to gratify them more fully upon another occasion, is approved of, as much under the aspect of propriety, as under that of utility. When we act in this manner, the sentiments which influence our conduct seem exactly to coincide with those of the spectator. The spectator, however, does not feel the solicitations of our present appetites. To him the pleasure which we are to enjoy a week hence, or a year hence, is just as interesting as that which we are to enjoy this moment. When for the sake of the present, therefore, we sacrifice the future, our conduct appears to him absurd and extravagant in the highest degree, and he cannot enter into the principles which influence it. On the contrary, when we abstain from present pleasure, in order to secure greater pleasure to come, when we act as if the remote object interested us as much as that which immediately presses upon the senses, as our {168} affections exactly correspond with his own, he cannot fail to approve of our behaviour: and as he knows from experience, how few are capable of this self-command, he looks upon our conduct with a considerable degree of wonder and admiration. Hence arises that eminent esteem with which all men naturally regard a steady perseverance in the practice of frugality, industry, and application, though directed to no other purpose than the acquisition of fortune. The resolute firmness of the person who acts in this manner, and in order to obtain a great though remote advantage, not only gives up all present pleasures, but endures the greatest labour both of mind and body, necessarily commands our approbation. That view of his interest and happiness which appears to regulate his conduct, exactly tallies with the idea which we naturally form of it. There is the most perfect correspondence between his sentiments and our own, and at the same time, from our experience of the common weakness of human nature, it is a correspondence which we could not reasonably have expected.
