Logic, one current argument goes, is the creation of defensive male subjects who have lost touched with their lived experience and define all being in rigid propositional categories modelled on a primal contrast between male and female. Or another: logic articulates oppressive thought-structures that channel human behavior into restrictive gender roles. Or: logic celebrates the unity of a pathological masculine self-identity that cannot listen and recognizes only negation and not difference. These critical evaluations have been made by sociolinguists studying the assymetries of male and female conversational styles, by poststructural feminist theorists struggling for an escape from the "prison house" of sexist language, and by psychoanalysts exploring the darkness of Freud's pre-Oedipal maternal.
