Pride, ill nature, and want of sense, are the three great sources of ill manners; without some one of these defects, no man will behave himself ill for want of experience, or of what, in the language of fools, is called knowing the world.
I defy any one to assign an incident wherein reason will not direct us what to say or do in company, if we are not misled by pride or ill nature.
Therefore I insist that good sense is the principal foundation of good manners; but, because the former is a gift which very few among mankind are possessed of, therefore all the civilized nations of the world have agreed upon fixing some rules upon common behaviour, best suited to their general customs or fancies, as a kind of artificial good sense, to supply the defects of reason. Without which the gentlemanly part of dunces would be perpetually at cuffs, as they seldom fail when they happen to be drunk, or engaged in squabbles about women or play. And, God be thanked, there hardly happens a duel in a year, which may not be imputed to one of these three motives. Upon which account, I should be exceedingly sorry to find the legislature make any new laws against the practice of duelling; because the methods are easy, and many, for a wise man to avoid a quarrel with honour, or engage in it with innocence. And I can discover no political evil in suffering bullies, sharpers, and rakes, to rid the world of each other by a method of their own, where the law has not been able to find an expedient.
As the common forms of good manners were intended for regulating the conduct of those who have weak understandings; so they have been corrupted by the persons for whose use they were contrived.
