Demerath rejects the view that psychogenic aberrations are absent among primitive tribes and the methods of field workers who disagree with him are questioned. However, he goes on to show quite correctly that wherever schizophrenia is frequently present in a 'primitive' group the people in question are not really primitive. To call the work of an anthropologist of C. G. Seligman's standing 'veiled and suspect', as the author does, is at least startling.
