" The Three Christs of Ypsilanti is a psychiatric case study by Rokeach, a detailing of his experiment with a trio of schizophrenic patients at Ypsilanti State Hospital in Ypsilanti, Michigan. The three men—who each harbored the delusional belief that he was Jesus Christ returned—were forced to live with each other in a mental hospital to see if their beliefs could be challenged enough to effect a break-through in at least one of them."
This looks a fascinating book- would be interested if anyone has read this and what they think.
