The recent history of Mathematical Logic was marked by some conficts between different philosophical positions, each trying to contextualize mathematical activity from its own analytical viewpoint and, with this, trying to conquer the foundational podium of the formal sciences for itself. Such discussions, lasting enough to remain without a solution, were strongly impacted by the semantical appropriation of some technical results obtained in the field of proof theory, which redefined the relation between the classical and intuitionistic approaches to mathematics. In this context, the present dissertation aims to describe the emergent literature about the integration of different logical and mathematical systems (nicknamed logical ecumenism by Dag Prawitz), in addition to investigating some impacts that those formal changes could have on the philosophical conceptions of some mathematical theories. In the introductory chapter, we have outlined a general overview of this new ecumenical proposal and analysed in greater depht the conflicts between Classical, Intuitionistic and Minimal logic, considered by many as one of the most influent on the contemporary literature. In the second chapter, this work provides an original contribution to the literature by creating a new ecumenical approach, in addition to proving some equivalencies within Prawitz s recently created Classical-Intuitionist system, and compares it with the logical system we have created using this new approach. In the third chapter, we contribute both to the traditional approach and our original approach by creating and comparing two Minimal-Intuitionist ecumenical logics. Finally, we briefly review the timid state of the art in the last chapter, offering a new conceptual framework for interpreting ecumenical systems, as well as commenting on some promising aspects of the field, which may be better analyzed in the future.
