The sub-title of this paper is 'A Religio-Psycho-analytical Study'. A study of Freud's book on Moses leads to the supposition that, though Freud identified himself with Moses on the basis of the unusual powers of leadership which both possessed, he also strongly resented Moses's Jewishness, perhaps unconsciously. Freud's book represents an unconscious attempt on his part to resolve his own religio-racial conflict, an attempt to rationalize his rejection of religion and to compensate his feeling of racial inferiority.
