of suiting, with exact justness, their sentiments and behaviour to the smallest difference of situation, and of acting upon all occasions with the most delicate and accurate propriety. The coarse clay of which the bulk of mankind are formed, cannot be wrought up to such perfection. There is scarce any man, however, who by discipline, education, and example, may not be so impressed with a regard to general rules, as to act upon almost every occasion with tolerable decency, and through the whole of his life to avoid any considerable degree of blame. Without this sacred regard to general rules, there is no man whose conduct can be much depended upon. It is this which constitutes the most essential difference between a man of principle and honour and a worthless fellow. The one adheres, on all occasions, steadily and resolutely to his maxims, and preserves through the whole of his life one even tenor of conduct. The other, acts variously and accidentally, as humour, inclination, or interest chance to be uppermost. Nay, such are the inequalities of humour to which all men are subject, that without this principle, the man who, in all his cool hours, had the most delicate sensibility to the propriety of conduct, might often be led to act absurdly upon the most frivolous occasions, and when it was scarce possible to assign any serious motive for his behaving in this manner. Your friend makes you a visit when you happen to be in a humour which makes it disagreeable to receive him: in your present mood his civility is very apt to appear an impertinent intrusion; and if you were to give way to the views of things which at this time occur, though civil in your temper, you would behave to him with coldness and contempt. What renders you incapable of such a rudeness, is nothing but a regard to the general rules of civility and hospitality, which prohibit it. That habitual reverence which your former experience has taught you for these, enables you to act, upon all such occasions, with nearly equal propriety, and hinders those inequalities of temper, to which all men are subject, from influencing your conduct in any very sensible degree. But if without regard to these general rules, even the duties of politeness, which are so easily observed, and which one can scarce have any serious motive to violate, would yet be so frequently violated, what would become of the duties of justice, of truth, of chastity, of fidelity, which it is often so difficult to observe, and which there may be so {144} many strong motives to violate? But upon the tolerable observance of these duties depends the very existence of human society, which would crumble into nothing if mankind were not generally impressed with a reverence for those important rules of conduct.
