Brain surgeon James Doty is on the cutting edge of our knowledge of the brain and the heart: how they talk to each other; what compassion means in the body and in action; and how we can reshape our lives and perhaps our species through the scientific and human understanding we are now gaining. The backstory of James Doty’s passions is told in his memoir, “Into the Magic Shop.” In the summer of 1968, in the throes of a hardscrabble, perilous childhood, he wandered into a magic shop and met a woman named Ruth who taught him what she called “another kind of magic” that freed him from being a victim of the circumstances of his life, and that he now investigates through science.
