One of the things I like is when egg-heads have marvelous “insights” that every parent could come up with if they thought it was worth writing a book about. Here is one shared by Jordan Peterson in his third lecture of his Biblical Series.
“One of the things I really like about Jean Piaget, the development psychologist, was that he was so insistent that children act out and dramatize ideas before they understand them. Merlin Donald, who is a psychologist at Queen’s University, wrote a couple of interesting books along those lines, as well, looking at the importance of imitation for the development of higher cognition in human beings. The notion that we embody ideas before we abstract them out, and then represent them in an articulated way, is an extraordinarily solid idea. I really can't see how it could be any other way. If you watch children, you see that.”He then goes on at length how this is demonstrated by children. I would guess that his audience is made up of childless individuals who never had brothers or sisters. My reaction is, “Well, duh.”
