The plain man on a plain day wakes up, slowly or quickly according to his temperament, and greets the day in a mental posture which might be thus expressed in words: ?Oh, Lord! Another day! What a grind!? If you ask me whom I mean by the plain man, my reply is that I mean almost every man. I mean you. I certainly mean me. I mean the rich and the poor, the successful and the unsuccessful, the idle and the diligent, the luxurious and the austere. For, what with the limits of digestion, the practical impossibility of wearing two neckties at once, the insecurity of investments, the responsibilities of wealth and of success, the exhaustingness of the search for pleasure, and the cheapness of travel, the real differences between one sort of plain man and another are slight in these times. (And indeed they always were slight).
