"I’m a man of science and a lover of history; after studying the classics at Princeton, I trained in psychiatry at Yale and in psychoanalysis at Columbia. ... For the past two-and-a-half decades and over several hundred consultations, I’ve helped clergy from multiple denominations and faiths to filter episodes of mental illness — which represent the overwhelming majority of cases — from, literally, the devil’s work. It’s an unlikely role for an academic physician, but I don’t see these two aspects of my career in conflict. The same habits that shape what I do as a professor and psychiatrist — open-mindedness, respect for evidence and compassion for suffering people — led me to aid in the work of discerning attacks by what I believe are evil spirits and, just as critically, differentiating these extremely rare events from medical conditions."
That's Richard Gallagher, a board-certified psychiatrist and a professor of clinical psychiatry at New York Medical College. More here.
