"It is significant that heart-transplant patients, where
the nerves connecting the heart and brain are severed, have serious
emotional problems after the operation... 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." (Watchtower, 3/1/1971 p.133-139)
