This dissertation proposes an analysis, from a subaltern studies approach, of representative texts within the category of “creole intellectual” and “creole reason.” Chapter one establishes the notion of “social justice” as the intellectual motivation of this project. Chapter two formulates a subaltern theorical framework that challenges the notions of “national culture” and the “literary field” in Mexico. Chapter three poses a cognitive approach to the personal archive or carnero of creole-mexican Lucas Alamán. Chapter four interrogates the biographical historiography of cultural icon of Mexican literature Ignacio Manuel Altamirano. Chapter five presents an interdisciplinary approach to the social context of production of the novel Perico (1885) by Arcadio Zentella. Chapter six presents the types of “Mexican people” formulated from the “creole reason” of intellectuals Antonio Caso, Samuel Ramos, Octavio Paz, Roger Bartra, and Pedro Ángel Palou. Chapter seven suggests that the Mexican State regulated the ideological content of Mexican film by presenting the case of famous wrestler and film icon El Santo. Chapter eight is a study of the Mexican social novel and its intersection with early Chicano literature. The notion of “creole reason” is inscribed in the project of interrogating the centrality and canonicity of creole intellectual productions that have given ethnic and intellectual legitimacy to the hegemonic idea of national culture. The dissertation, hence, seeks to study and criticize a Mexican intellectual tradition that imagined creole intellectuals as superior to other national collectivities, such as indigenous, afromexican, mestizo groups, and Mexican immigrants in the United States. I define “creole reason” as a historical and ontological narrative expression that places the national “other” in the intellectual margins of the nation state. In these terms, the dissertation is focused on the study of creole intellectuals and their cultural production, from XIX-century creole Lucas Alamán to XXI-century creole Roger Bartra, as evidence of the systemic intellectual discrimination that has shaped intellectual history in Mexico. This study is thus focused on intellectual manifestations that challenge the notion of creole intellectual and creole reason as dystopic nation-building ideologies that have systematically segregated the majority of the nation based on ethnic, class, and historical origins.
