The revelations of Mohammed, too, were—we are told—the result of "a midlife crisis" and "a condition similar to epilepsy". Although his early "hallucinatory revelations"   http://www.noetic.org/Ions/publications/review_archives/02/issue02_25.html   appear to have been spontaneous, during an epileptic seizure, later on "Mohammed deviously resorted to 'making up' revelations to suit his political and private purposes." (p. 215) So much for the Koran.
