Carlos Castaneda originally said he was born on Dec. 25, 1935, in Sao Paolo, Brazil, the son of a university professor and a woman who died when he was 7. American immigration records indicated he was born in 1923 in Cajmarca, Peru, the son of a goldsmith, and that his mother died when he was 24. Aside from his dubious biography and shamanlike tales of having doubles, pulverizing glass or powering cars with his spirit is the question of what to make of his books. Few academics regard them as serious scholarship.

Among anthropologists, there's no longer a debate. Professor William W. Kelly, chairman of Yale's anthropology department, told me, "I doubt you'll find an anthropologist of my generation who regards Castaneda as anything but a clever con man. It was a hoax, and surely don Juan never existed as anything like the figure of his books. Perhaps to many it is an amusing footnote to the gullibility of naive scholars, although to me it remains a disturbing and unforgivable breach of ethics."
