In my thesis, I engage with recent scholarship in Mad Studies directed towards introducing a Mad reading practice or Mad theory to the discipline of English and academia more broadly. I utilize Mad theory and feminist literary criticism in order to frame my analysis of two forgotten queer Madwomen—British author Ann Quin (1936-1973) and American author, artist, and activist Kate Millett (1934-Present). I consider how Quin’s novel Three (1966) and Millett’s autobiography Flying (1974), as experimental texts exploring bisexuality and polyamory que(e)ry heteronormative monogamy and patriarchal literary convention. I also posit that Quin’s “The Unmapped Country” (1973) and Millett’s The Loony-Bin Trip (1990) deconstruct a perceived tension in feminist literary criticism surrounding whether the figure of the Madwoman is a subversive or silenced figure. In using a Mad reading practice, my analysis focuses on the intersections of sanism with other forces of oppression, as well as how sanist epistemic violence dissuades critically analyzing Mad individuals’ creative or personal narratives as theoretical and political texts. Moreover, I gesture towards the overlooked social exclusions produced by sanist epistemic violence, such as forced institutionalization, unemployment, criminalisation, and homelessness, which suggests the ethical importance of incorporating Mad theory into everyday practice. / Thesis / Master of Arts (MA)
