An interesting report comes from El Retiro, the experimental school for correctional education established by the city and county of Los Angeles during the war. Of two hundred girls passing through this institution during the first three years, only two have drifted to the underworld, these being drug addicts when they came from the court. One hundred and ninety-eight are functioning socially in the community. These girls were all under twenty-one years. On arriving at El Retiro each girl is studied by a group consisting of the referee of the court, the psychologist, the superintendent, the teacher and the head of student government. So soon as her interests and special abilities are discovered, a project is chosen which will prepare her for constructive living in the community. The girls are stimulated to mental expression of energy, not set to hours of dull routine, scrubbing floors or paring potatoes. Not punishment but responsibility develops power and leads to higher expression and achievement. Science is teaching us that man is an epitome of the past,—that in each human being is retained the impress of prehuman behavior. As one analyst puts it, “Each day is an adjustment between the higher nerve centers and the spinal column.” We must study this conservation of life force that we may strengthen those manifestations which show ascending effort and decrease the tendency to revert to action patterns of earlier forms. A dictum of the percipient mind of the biologist-sociologist, Lester Ward, should startle us into fresh appraisal of life’s values. Shortly before his death he said, “The day will come when society shall be as much shocked at the crime of perpetuating the least taint of hereditary disease, insanity or other serious defect, as it is now at the comparatively harmless crime of incest.” As an equation is solved more simply by algebra than arithmetic, so any subject carried up into the next higher universe of discourse becomes clarified, falls into proper perspective, and is more easily understood. This thought in conjunction with the statement of Lester Ward shows the need of extending our discussion to include women both in and out of wedlock, and instead of differentiating the good from the bad by legal definition, the ethics of human mating must be based upon those laws of nature which secure the finest human values, the essential aim being an ever better next generation.
