But by a process, an evolution, connected with mechanical inventions, facilitated communication, the diffusion of print, the growth of cities, business organization, the capitalistic system, specialized occupations, scientific research, doctrines of freedom, the evolutionary view of life, etc., the family and community influences have been weakened and the world in general has been profoundly changed in content, ideals, and organization. Young people leave home for larger opportunities, to seek new experience, and from necessity. Detachment from family and community, wandering, travel, “vagabondage” have assumed the character of normality. Relationships are casualized and specialized. Men meet professionally, as promoters of enterprises, not as members of families, communities, churches. Girls leave home to work in factories, stores, offices, and studios. Even when families are not separated they leave home for their work. Every new invention, every chance acquaintanceship, every new environment, has the possibility of redefining the situation and of introducing change, disorganization or different type of organization into the life of the individual or even of the whole world. Thus, the invention of the check led to forgery; the sulphur match to arson; at present the automobile is perhaps connected with more seductions than happen otherwise in cities altogether; an assassination precipitated the World War; motion pictures and the _Saturday Evening Post_ have stabilized and unstabilized many existences, considered merely as opportunity for new types of career. The costly and luxurious articles of women’s wear organize the lives of many girls (as designers, artists, and buyers) and disorganize the lives of many who crave these pretty things.
