electric shocks to a screaming "victim." In the second, the infamous Stanford prison experiment, the planned two-week investigation into the psychology of prison life had to be ended after only six days because the college students who were assigned to act as guards became sadistic and those who were the "prisoners" became depressed and showed signs of extreme stress. These and other experiments are taken to show that if humans do have noble tendencies, they are narrow, "local" traits that are not unified with other traits into a wider behavioral pattern of being. History of character education in U.S. schools The colonial period 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. Character education in school in the United States began with the circulation of the New England Primer. Besides rudimentary instruction in reading, it was filled with Biblical quotes, prayers, catechisms and religiously charged moral exhortations. Typical is this short verse from the 1777 edition: Good children must, Fear God all day, Love Christ alway, Parents obey, In secret pray, No false thing say, Mind little play, By no sin stray, Make no delay, In doing good. Nineteenth century As the young republic took shape, schooling was promoted for both secular and moral reasons. By the time of the nineteenth century, however, religion became a problem in the schools. In the United States, the overwhelming dominant religion was Protestantism. While not as prominent as during the Puritan era, the King James Bible was, nevertheless, a staple of U.S. public schools. Yet, as waves of immigrants from Ireland, Germany, and Italy came to the country from the mid-nineteenth century forward, they reacted to the Protestant tone and orthodoxy of the schools. Concerned that their children would be weaned from their faith, Catholics developed their own school system. Later in the twentieth century, other religious groups, such as Jews, Muslims, and even various Protestant denominations, formed their own schools.
