We might say that the younger children take in things sensorially. The child of seven enters the abstract field, he wishes to know reasons. It is curious to notice that one of the things which preoccupy these children is what is ethical in life: what is good, what is bad. If you tell the little child that he is bad or good, he just accepts it. Whereas the seven-year-old wants to know why he is bad, and what it is to be bad etc.
