But the person habitually wearing a corset does not feel these evils. They exist, assuredly, the facts are there, the body is not deceived; but the nerves have become accustomed to these disagreeable sensations, and no longer respond to them. The person “does not feel it.” In fact, the wearer becomes so used to the sensations that, when they are removed,—with the corset,—there is a distinct sense of loss and discomfort. The heavy folds of the cravat, stock, and neckcloth of earlier men’s fashions, the heavy horse-hair peruke, the stiff high collar of to-day, the kind of shoes we wear,—these are perfectly familiar instances of the force of habit in the individual. This is equally true of racial habits. That a king should rule because he was born, passed unquestioned for thousands of years. That the eldest son should inherit the titles and estates was a similar phenomenon as little questioned. That a debtor should be imprisoned, and so entirely prevented from paying his debts, was common law. So glaring an evil as chattel slavery was an unchallenged social institution from earliest history to our own day among the most civilized nations of the earth. Christ himself let it pass unnoticed. The hideous injustice of Christianity to the Jew attracted no attention through many centuries. That the serf went with the soil, and was owned by the lord thereof, was one of the foundations of society in the Middle Ages. Social conditions, like individual conditions, become familiar by use, and cease to be observed. This is the reason why it is so much easier to criticise the customs of other persons or other nations than our own. It is also the reason why we so naturally deny and resent the charges of the critic. It is not necessarily because of any injustice on the one side or dishonesty on the other, but because of a simple and useful law of nature. The Englishman coming to America is much struck by America’s political corruption; and, in the earnest desire to serve his brother, he tells us all about it. That which he has at home he does not observe, because he is used to it. The American in England finds also something to object to, and omits to balance his criticism by memories of home. When a condition exists among us which began in those unrecorded ages back of tradition even, which obtains in varying degree among every people on earth, and which begins to act upon the individual at birth, it would be a miracle past all belief if people should notice it. The sexuo-economic relation is such a condition. It began in primeval savagery. It exists in all nations. Each boy and girl is born into it, trained into it, and has to live in it. The world’s progress in matters like these is attained by a slow and painful process, but one which works to good ends.
