I soon began to sense a fundamental perceptual difficulty among male scholars (and some female ones) for which 'sexism' is too facile a term. It is really an intellectual defect, which might be termed 'patrivincialism' or patrochialism': the assumption that women are a subgroup, that men's culture is the 'real' world, that patriarchy is equivalent to culture and culture to patriarchy, that the 'great' or 'liberalizing' periods of history have been the same for women as for men.
