your heart? You may say, What heart are you talking about? You know you
have a heart in your chest, one that is pumping blood throughout your
entire body, serving every single cell with that stream of life. But do
you have another “heart” in your head, a “figurative heart”? Is it part
of your brain or is it that abstract capacity of the brain that we call
the “mind”? No! The brain, in which the mind resides, is one thing and
the heart in our thorax, with its power of motivation, is another thing.

was one of the first to receive a transplanted heart. His daughter
observed: “I don’t know if it was the drugs or just the transplant, but
he was a different man.”
