Sexual discussion and sexual immorality have always been parts of one circle; sexual silence and moral restraint form another circle. The change from one to the other has come in the history of mankind, usually through new conditions of life, and the primary factor has not been any policy of keeping quiet in respect or of gossiping in curiosity, but the starting point has generally been a change in the life habits. When new wealth has come to a people with new liberties and new desires for enjoyment, the great periods of sexual frivolity have started and brought secondarily the discussions of sex problems, which intensified the immoral life. On the other hand, when a nation in the richness of its life has been brought before new great responsibilities, great social earthquakes and revolutions, great wars for national honour, or great new intellectual or religious ideals, then the sexual tension has been released, the attention has been withdrawn from the frivolous concerns, and the people have settled down soberly to a life of modesty and morality, which brought with it as a natural consequence the policy of reverence and silence. The new situation in America, and to a certain degree all over the world, has come in, too, not through the silence of the preceding generation, but by the sudden change from agricultural to industrial life, with its gigantic cumulation of capital, with its widespread new wealth, with its new ideas of social liberty, with its fading religion, with its technical wonders of luxury and comfort. This new age, which takes its orders from Broadway with its cabarets and tango dances, must ridicule the silence of our fathers and denounce it as a conspiracy. It needs the sexual discussions, as it craves the lurid music and the sensual dances, until finally even the most earnest energies, those of social reform and of hygiene, of intellectual culture and of artistic effort, are forced into the service of this antimoral fashion.
