Modernist knowledge has been critiqued as being sexist. This chapter examines knowledge systems and then knowledge protocols. It is knowledge about men, men's activities, achievements and interests, constructed by men, according to criteria and values which are important to men. Homophobic prejudice has been reinforced by school and university knowledge: the way in which the Aids scare has been transposed into health education. It is in educational institutions that this version of medicine is taught. It is important to emphasise that this does not involve only university medical schools. It is a mode of analysis which urgently needs to be conducted with regard to a whole range of curricular areas. How much of the literature studied in schools and universities, for instance, has been written by people perceived to be disabled? The knowledge of schools and universities is almost exclusively that which will perpetuate modes of production which exacerbate the ecological crises.
