  For example, feminist epistemology is a philosophically innovative reform movement that can serve as a beacon for the philosophical investigation of disability, although as of this writing the significance of disability for an adequate epistemology has not been much explored in disability scholarship, neither in the philosophical study of disability or in disability studies generally. Some feminist philosophers (and some feminist psychologists as well) have argued that women have ways of knowing that differ from men's. (For psychologists, see Belenky et al. 1986 and Tannen 1990; for philosophers, see Code 1991 and Ruddick 1989) Tannen, for example, adduces evidence from sociolinguistic research to argue that environments conducive to women's learning differ from those appropriate for men. More generally, some theorists influenced by such accounts have characterized women as being alienated, unsatisfied, and unconvinced when held to traditional epistemology's paradigm of the isolated knower, with its detached, universalizing, and controlling approach to knowledge. Dissatisfaction with this kind of view has prompted feminist epistemological insights about the possibilities for achieving objectivity without insisting that cognition works or should work the same way for everyone, as well as about the importance of situating, contextualizing, and nuancing truths, and about the benefits of collaborative practices of achieving knowledge.
