Why (again we ask) did Christianity make this apparently great mistake? And again we must reply: Perhaps the mistake was not so great as it appears to be. Perhaps this was another case of the necessity of learning by loss. Love had to be denied, in the form of sex, in order that it might thus the better learn its own true values and needs. Sex had to be rejected, or defiled with the sense of guilt and self-seeking, in order that having cast out its defilement it might return one day, transformed in the embrace of love. The whole process has had a deep and strange world-significance. It has led to an immensely long period of suppression--suppression of two great instincts--the physical instinct of sex and the emotional instinct of love. Two things which should naturally be conjoined have been separated; and both have suffered. And we know from the Freudian teachings what suppressions in the root-instincts necessarily mean. We know that they inevitably terminate in diseases and distortions of proper action, either in the body or in the mind, or in both; and that these evils can only be cured by the liberation of the said instincts again to their proper expression and harmonious functioning in the whole organism. No wonder then that, with this agelong suppression (necessary in a sense though it may have been) which marks the Christian dispensation, there should have been associated endless Sickness and Crime and sordid Poverty, the Crucifixion of animals in the name of Science and of human workers in the name of Wealth, and wars and horrors innumerable! Hercules writhing in the Nessus-shirt or Prometheus nailed to the rocks are only as figures of a toy miniature compared with this vision of the great and divine Spirit of Man caught in the clutches of those dread Diseases which through the centuries have been eating into his very heart and vitals.
