Before any attempt is made to solve the problem with which this paper deals, it is necessary to convince the reader that the problem exists. Much is written and said to-day about class distinctions, both by those who announce with satisfaction their growing disappearance, and by those who half guiltily admit their existence, but it never seems to occur to such writers that the nature of these distinctions is itself something of a mystery. We take it for granted as one of the most obvious and commonplace facts of daily life. It seems hardly likely that the examination of a thing so ubiquitous and immemorial will yield anything new. My object will be to maintain that this attitude is mistaken, and that the idea of “class” is not really self-explanatory, but deserves a closer analysis than it usually gets. And if this proves to be the case, it must be admitted that the subject is of importance. Many political and social problems are deeply involved in the fact of class distinctions. Many who believe in a possible regeneration of human society would gladly surrender much to secure a world where poverty should be no more, yet hesitate before the prospect of a loss, through diffusion, of cultural values which they feel to be infinitely precious, and which give to the existing order a greater claim to permanence than it would otherwise possess. We most of us hardly know our own minds in this matter. We yield social distinctions their place, but we do so shamefacedly, as though confessing to a mere unjustified conservatism.
