“Mothers who have little sense of their own minds and voices are unable to imagine such capacities in their children. Not being fully aware of the power of words for communicating meaning, they expect their children to know what is on their minds without the benefit of words. These parents do not tell their children what they mean by “good” much less why. Nor do they ask the children to explain themselves.”

—Ralph Waldo Emerson (1803–1882)
