we hear people speak as if the mind controlled or at least influenced the body, but more frequently mental life is vaguely referred to as if it were simply awareness of what is taking place in the body, together with sensations which arise from external sources; for instance, sensations of warmth and cold, of sound, and light. As if in confession that this is a faulty view we hear them also referring to the mind as if this term were synonymous with "intellect," and had nothing to do with sensations and the will. Again, they refer to the will in connection with statements about character, and a lament is expressed that it is difficult to arouse this "faculty" into successful exercise. Instances are sometimes cited to prove that the will controls the organism, but the problem then is to reconcile this notion with the other one, as often quoted, namely, that the mind is a prisoner in the brain, dependent on processes of nutrition and blood-supply. We scarcely think of pain except when ill, and then merely because our attention is drawn to a certain locality within the organism. We do not analyse pleasure, for we are eager to enjoy it while it lasts. Our emotions sweep through the mind so rapidly that we know little about them, to say nothing of controlling them. Commonly we make no distinction between sensations, pleasures, pains, or emotions, but uncritically class them all as "feelings."
