If this activity is necessary for thinking, it is also necessary for carrying thought from one person to another. Observe how people go about the business of ordinary conversation. If you have never done this painstakingly, you have a surprise in store, for good conversationalists are almost constantly in motion. Their heads are continually nodding and shaking sometimes so vigorously that you wonder how their necks can stand the strain.

　　Even the legs and feet are active. As for the hands and arms, they are seldom still for more than a few seconds at a time.

　　These people, remember, are not making speeches. They are merely common folk trying to make others understand what they have in mind. They are not conscious of movement.

　　In short, because people really think all over, a speaker must talk all over if he succeeds in making people think.
