I would nominate Dawkins as the man most likely to benefit. Hallucinogens often produce mystical experiences indistinguishable from religious revelations - c.f. "The Miracle of Marsh Chapel". Dawkins is a seeker - see "God on the brain" - http://www.youtube.com/watch?v=Y_-txbHNyOY He should probably take some of the classical god medicine. At the moment, he hasn't witnessed what he is talking about. Maybe Sam Harris will turn him on.
