This dissertation starts with Gayatri Spivak s diagnosis on the subaltern. More specifically, in Chapters 2-3, Spivak s conclusion about the subaltern disability to speak becomes a sort of gravity center around which orbitate theoretical problematizations, conceptual articulations, critiques and argumentative proposals. In many degrees, this dissertation follows Spivak s proposition, in that it does not intend to prove Spivak s diagnosis wrong. It does aim, however, to show how such diagnosis is incomplete. In that sense, Chapter 3 questions whether the subaltern translates a life form of the modern/colonial system that can only be demarcated by its exclusion from the symbolic arena. With this problematization, the general objective is to move away from a strictly epistemological take on the subaltern problematique towards an ontological turn capable of appreciating the experience of indeterminacy as having an ontological status of its own. In order to construct that turn, the dissertation articulates subaltern studies with Lacanian psychoanalysis contributions. Drawing in Lacan s concepts, chapter 4 tries to find a grammar capable to interpret both the subaltern s expulsion from experience and the subaltern s experiences of denial. Hence, while that first level of interpretation is accomplished through a rereading of Lacan s theory of foreclosure along with subalternalists reflections, the second one is sustained by a critical engagement with Lacan s conceptualizations around the register of Real and its operations as drives - generally related with inverted returns, desublimation, and crossing of fantasy. The Chapter 5 combines such theoretical preoccupation with concrete examples, meanings, and historical contexts related to Latin America reality. In particular, Chapter 6 focus in the case of female workers, which points towards political dynamics that embrace the diagnoses of loss mentioned above. The role of this final moment is to bring an analytical piece capable of offering a historical application of the conceptual grammar about the subaltern as it was developed along the previous chapters of the dissertation.
