Criticism of Christianity
editLeffmann authored a pamphlet The Mental Condition and Career of Jesus of Nazareth in 1904. He argued that Jesus was a megalomaniac and that much of his phenomena could be explained by hypnosis and suggestion. Leffmann was an advocate of the swoon hypothesis, arguing that Jesus did not die on the cross, but was "tenderly cared for, probably by the mother and brothers whom he had disowned and scorned, and quietly buried after his death, which may have occurred very soon afterwards."[6]
