Take, for example, a wonderful scene in the film The Karate Kid. The teenaged Daniel asks the wise and wily Mr. Miyagi to teach him karate. The old man agrees and orders Daniel first to wax his car in precisely opposed circular motions (“Wax on, wax off”). Then he tells Daniel to paint his wooden fence in precise up and down motions. Finally, he makes Daniel hammer nails to repair a wall. Daniel is puzzled at first, then angry. He wants to learn the martial arts so he can defend himself. Instead he is confined to household chores. When Daniel is finished restoring Miyagi’s car, fence, and walls, he explodes with rage at his “mentor.” Miyagi physically attacks Daniel, who without thought or hesitation defends himself with the core thrusts and parries of karate. Through Miyagi’s deceptively simple chores, Daniel has absorbed the basics of karate—without knowing it.
