The North and the global South are separated not only by the Equator, but also by an abyssal thinking, as emphasized by the author Portuguese Boaventura de Sousa Santos, which presents the Modern Western Thought as responsible for making invisible, non existent, the knowledge produced and practiced by humans in the global South, while the North is global hegemonic in its being, being and doing in the world. However, the South epistemologies exist and can help you understand how to practice co-presence, until now denied by abyssal thinking that makes the hegemonic global North. So, open up possibilities for exploring parallel understanding epistemologies North of Brazil, located in the global South, since the existence of abyssal thinking global instigates us to also discuss the hypothesis of a thought abysmal environmental Brazil, definer a line; 'this side of the line' is the Southeast and 'across the line' is the North of Brazil, in which context the North represents all other regions, except the Southeast. Epistemologies of southeastern Brazil are assumed hegemonic, but need to be deconstructed to the revelations engendered research on the epistemologies of the North Country, thereby reconstruct a Brazilian thought, where North, South, Southeast, Northeast and Midwest recognize physical geography and politics of Brazil, without forgetting that the human being in any geographical locations and under different political contexts are diverse, complex, and this has to be knowledge and expertise, and must take up counter-hegemonic, while there is no hegemony . The beginning of the reconstruction process is understanding how the sociology of absences makes this all that was made invisible by the logic and methods of production of non existence and presents the ecology of knowledge as an antidote to the production of absences, because that will represent the ecology superstructure built this new thinking replacement of abyssal thinking of Southeastern Brazil hegemonic. The purpose of this article, therefore, is to explore the possibilities of epistemologies of Northern Brazil for the construction of Brazilian thought.
