This thesis seeks to gather a corpus of thoughts about writing experiences from women writers. The choice of authors was established through our interest in the relationship between the experiences of writing and of madness for women who write. Writers such as Alfonsina Storni and Marguerite Duras figure at the basis of these reflexions, sought to be developed from the following axes: (a) in an effort toward a critical reading of Silvia Federici, to think the essential role that oppression of women had on the establishment of capitalism, linking socioeconomic oppression to subjective and corporal oppression (reproduction techniques, the right to sexuality and the use of one s own body); and its effects on the experience of writing, its impossibility, strangulation and madness; (b) a rereading of psychoanalysis by contemporary feminism, through which we will try to think how the construct feminine madness is directly related to the necessity of this exclusion; (c) how certain feminist literary theory thinks the specificities of women s writing, both from the bias of the material conditions of writing and from the literary work itself, which summons a body that writes / a woman s body that writes. From then, we try to elaborate a reading of some of the Argentinean Alejandra Pizarnik s and the Brazilian Maura Lopes Cançado s works, their indomability fulgurating on language / body, the force that helps writing s normativity escape its territory of the Law, towards (or becoming) a tameless language and its performativity: it matters not writing about madness but driving crazy the Letter.
