“What is clear is that Christianity directed increased attention to childhood. For the first time in history it seemed important to decide what the moral status of children was. In the midst of this sometimes excessive concern, a new sympathy for children was promoted. Sometimes this meant criticizing adults. . . . So far as parents were put on the defensive in this way, the beginning of the Christian era marks a revolution in the child’s status.”
—C. John Sommerville (20th century)

“The scholar was not raised by the sacred thoughts amongst which he dwelt, but used them to selfish ends. He was a profane person, and became a showman, turning his gifts to marketable use, and not to his own sustenance and growth. It was found that the intellect could be independently developed, that is, in separation from the man, as any single organ can be invigorated, and the result was monstrous.”
—Ralph Waldo Emerson (1803–1882)

“Play is a major avenue for learning to manage anxiety. It gives the child a safe space where she can experiment at will, suspending the rules and constraints of physical and social reality. In play, the child becomes master rather than subject.... Play allows the child to transcend passivity and to become the active doer of what happens around her.”
—Alicia F. Lieberman (20th century)
