Are we just thinking with our heads？ No. The human brain is just like a telephone switchboard （总机），but not a whole system. Its function is to receive incoming signals, establish appropriate connections, and send the information to its destination. In order to provide efficient service, the body must function as a whole.
But where is the mind？ Is it in the brain？ Or the nervous system？ Can we say that the mind is in a particular place？ In fact, the mind is not a thing, not a leg, and not even a brain. Thinking is both a function and an activity. Aristotle, 2300 years ago, noted that the mind is to the body what the tool is to the worker. When the tool is not in use, there is no work. Charles Woolbert said that consciousness is what the body does.
If this activity is necessary for thought,it is also necessary for the transmission of thought from one person to another. Observe how people conduct their daily conversations. If you've never taken the trouble to do this,you'll have a surprise waiting for you,because good conversationalists are almost always in motion. Their heads nodded and nodded,sometimes so violently that you wondered how their necks could withstand the strain. Even the legs and feet are active. As for hands and arms,they rarely stay still for more than a few seconds at a time.
Remember, these people are not giving speeches. They're just people, trying to get their points of view across. They have no sense of movement. Their language has not been studied. They're just human beings in a human environment, trying to adapt to the social environment. However, their conversation is not only verbal, but also visual, involving almost every muscle in the body. Briefly, because people are really thinking, the speaker must be everywhere if he is to succeed in getting people to think.
