Radical humanists want to release people from constraints - which largely reside in their own cognitions. They seek transformation, emancipation, and critical analysis of modes of domination. They want people to reconstruct their view of reality and take appropriate action. Participatory research, popularized by the International Council of Adult Education, springs from similar ontological and ideological roots. Advocates of participatory research are critical of the top down nature of much university or traditional research.
Participatory research is based on praxis - reflection followed by action.
It tends to unmask and then attempt to do something about unequal power relations. The learner dropped out or resists because of a lack of motivation, inferior intelligence or a bad attitude. Hence, feminism is in the radical humanism zone but has a leg in radical functionalism. There is also an exceedingly active branch of feminism nested in the postmodern. Critical social theory is a brand of western marxism and exemplified by a range of writers but most notably Habermas and others associated with the Frankfurt School.
