I am currently pursuing the research project Knowledge and Reasoning. The goal is to produce new insights into the role of knowledge in theoretical reasoning. The project is ambitious and it involves traditional and formal epistemology, metaphysics, philosophy of mind, and social psychology. The research is partially funded by PUCRS and by the federal government of Brazil and it engages almost ten members between undergraduate, master’s and doctorate students. Some of my recent and forthcoming work disseminates key epistemological results of this research. This work is featured in volumes of collected papers with Oxford University Press and Springer, as well as in articles in collections and journals such as Synthese and Erkenntnis. A network of philosophers in four different continents and at the top of the profession also contributes to these and other aspects of the project.
