Let this truth be remembered, by such as shall read the following pages. We are to think about disagreeable people. Let it be understood that (speaking generally) we are to think of people who are no worse than disagreeable. It cannot be denied, even by the most prejudiced, that murderers, pirates, slave-drivers, and burglars, are disagreeable. The cut-throat, the poisoner, the sneaking black-guard who shoots his landlord from behind a hedge, are no doubt disagreeable people,--so very disagreeable that in this country the common consent of mankind removes them from human society by the instrumentality of a halter. But disagreeable is too mild a word. Such people are all that, and a great deal more. And accordingly they stand beyond the range of this dissertation. We are to treat of folk who are disagreeable, and not worse than disagreeable. We may sometimes, indeed, overstep the boundary-line. But it is to be remembered that there are people who in the main are good people, who yet are extremely disagreeable. And a further complication is introduced into the subject by the fact, that some people who are far from good are yet unquestionably agreeable. You disapprove them; but you cannot help liking them. Others, again, are substantially good; yet you are angry with yourself to find that you cannot like them. I take for granted that all observant human beings will admit that in this world there are disagreeable people. Probably the distinction which presses itself most strongly upon our attention, as we mingle in the society of our fellow-men, is the distinction between agreeable people and disagreeable. There are various tests, more or less important, which put all mankind to right and left. A familiar division is into rich and poor. Thomas Paine, with great vehemence, denied the propriety of that classification, and declared that the only true and essential classification of mankind is into male and female. I have read a story whose author maintained, that, to his mind, by far the most interesting and thorough division of our race is into such as have been hanged and such as have not been hanged: he himself belonging to the former class. But we all, more or less, recognize and act upon the great classification of all human beings into the agreeable and the disagreeable. And we begin very early to recognize and act upon it. Very early in life, the little child understands and feels the vast difference between people who are nice and people who are not nice. In school-boy days, the first thing settled as to any new acquaintance, man or boy, is on which side he stands of the great boundary-line. It is not genius, not scholarship, not wisdom, not strength nor speed, that fixes the man's place. None of these things is chiefly looked to: the question is, Is he agreeable or disagreeable? And according as that question is decided, the man is described, in the forcible language of youth, as "a brick," or as "a beast."
