There has grown up universally an identification of mind with intelligence. Partly because the guidance of our actions by thought is so conspicuous, and partly because speech, which occupies so large a space in our lives, is a vehicle that makes thought predominant to ourselves and others, we are led to suppose that the thought-element of mind is its chief element: an element often excluding from recognition every other. Consequently, when it is said that the brain is the organ of the mind, it is assumed that the brain is chiefly if not wholly the organ of the intellect. The error is an enormous one. The chief component of mind is feeling. To see this it is necessary to get rid of the wrong connotations which the word mind has acquired, and to use instead its equivalent—consciousness.
