Somepsychologists maintain that mental acts such as thinking are not performed inthe brain alone, but that one's muscles also participate. It may be said thatwe think with our muscles in somewhat the same way that we listen to music withour bodies. Yousurely are not surprised to be told that you usually listen to music not onlywith your ears but with your whole body. Few people can listen to music that ismore or less familiar without moving their body or, more specifically, somepart of their body. Often when one listens to a symphonic ( 交响乐 ) concert on the radio, he is tempted to direct the orchestra hough he knows there is a competent conductor on the job. Strangeas this behavior may be, there is a very good reason for it. One cannot deriveall possible enjoyment from music unless he participates, so to speak, in itsperformance. The listener "feels" himself into the music with more orless pronounced motions of his body. Themuscles of the body actually participate in the mental process of thinking inthe same way, but this participation is less obvious because it is lesspronounced. 1.
