Has the racial stock changed in one generation or two? No. A new social heredity has overcome--or at least in part supplanted--an older social heredity and released and developed characters hitherto held in check. In every human being--and this is a theme we shall enlarge upon later--there are potential lines of development far outnumbering those that can be manifested, and each environment and tradition calls forth some and suppresses others. Every man is a garden planted with all kinds of seeds; tradition and teaching are the gardeners that allow only certain ones to come to bloom. In each age, each country and each family there is a different gardener at work, repressing certain trends in the individual, favoring and bringing to an exaggerated growth other trends. That each family, or type of family, acts in this way is recognized in the value given to the home life. The home, because of its sequestration, allows for the growth of individual types better than would a community house where the same traditions and ideals governed the life of each child. In the home the parents seek to cultivate the specific type of character they favor. The home is par excellence the place where prejudice and social attitude are fostered. Though the mother and father seek to give broadmindedness and wide culture to the child, their efforts must largely be governed by their own attitudes and reactions,--in short, by their own character and the resultant examples and teaching. It is true that the native character of the child may make him resistant to the teachings of the parents or may even develop counter-prejudices, to react violently against the gardening. This is the case when the child is of an opposing temperament or when in the course of time he falls under the influence of ideals and traditions that are opposed to those of his home. Unless the home combines interest and freedom, together with teaching, certain children become violent rebels, and, seeking freedom and interest outside of the home, find themselves in a conflict, both with their home teaching and the home teachers, that shakes the unity and the happiness of parent and child. Like all civil wars this war between new and old generations reaches great bitterness. In studying the cases of several hundred delinquent girls, as a consultant to the Parole Department of Massachusetts, it was found that the family life of the girls could be classified in two ways. The majority of the girls that reached the Reformatory came from bad homes,--homes in which drunkenness, prostitution, feeble-mindedness, and insanity were common traits of the parents. Or else the girls were orphans brought up by a stepmother or some careless foster mother. In any case, through either example, cruelty or neglect, they drifted into the streets.
