As common schools spread throughout the colonies, the moral education of children was taken for granted. Formal education had a distinctly moral and religion emphasis. In the Christian tradition, it is believed that humans are flawed at birth (original sin), requiring salvation through religious means: teaching, guidance and supernatural rituals. This belief in America, originally heavily populated by Protestant immigrants, creates a situation of a-priori assumption that humans are morally deficient by nature and that preemptive measures are needed to develop children into acceptable members of society: home, church and school.
