 Stein began to accept and define her pseudo-masculinity through the ideas of Otto Weininger's "Sex and Character" (1906).Weininger, though Jewish by birth, considered Jewish men effeminate and women as incapable of selfhood and genius, except for female homosexuals who may approximate masculinity.As Stein equated genius with masculinity, her position as a female and an intellectual becomes difficult to synthesize and modern feminist interpretations of her work have been called into question.
