1971 "How Is Your Heart? … The heart, nevertheless, is intricately connected with the brain by the nervous system and is well supplied with sensory nerve endings. The sensations of the heart are recorded on the brain. It is here that the heart brings to bear on the mind its desires and its affections in arriving at conclusions having to do with motivations. In reverse flow, the mind feeds the heart with interpretations of the impulses from the senses and with conclusions reached that are based on the knowledge it has received, either at the moment or from the memory. There is a close interrelationship between the heart and the mind, but they are two different faculties, centering in different locations. The heart is a marvelously designed muscular pump, but, more significantly, our emotional and motivating capacities are built within it. Love, hate, desire (good and bad), preference for one thing over another, ambition, fear-in effect, all that serves to motivate us in relationship to our affections and desires springs from the heart. … It is significant that heart-transplant patients, where the nerves connecting the heart and brain are severed, have serious emotional problems after the operation. The new heart is still able to operate as a pump, it having its own power supply and timing mechanism independent of the general nervous system for giving impulse to the heart muscle, but just as it now responds only sluggishly to outside influences, the new heart in turn registers few, if any, clear factors of motivation on the brain. To what extent the nerve endings of the body and the new heart are able to make some connections in time is not clear, but this cannot be ruled out as one of the several factors causing the serious mental aberrations and disorientation that doctors report are observed in heart-transplant patients. These patients have donor-supplied pumps for their blood, but do they now have all the factors needed to say they have a "heart"? One thing is sure, in losing their own hearts, they have had taken away from them the capacities of "heart" built up in them over the years and which contributed to making them who they were as to personality."
