I am CNPq researcher since 1992. I am associate professor of philosophy at the UFRN (Brazil). After a medical doctor study, I made my M.S. in philosophy at the IFCS (Rio de Janeiro, 1982), followed by a Ph.D. at the university of Konstanz (1990). I also made Sabbatical stages of one year as a visiting scholar in the Hochschule für Philosophie, München (1995), University of California at Berkeley (1999), University of Oxford (2004) and university of Konstanz (2009-10).
Areas of interest: all the central questions of philosophy.
Main published work: The Philosophical Inquiry (UPA: Langham, 2002), "Free Will and the Soft Constraints of Reason" (Ratio 2006), "The Sceptical Deal with our Concept of External Reality" (Abstracta 2009), "A Perspectival Definition of Knowledge" (Ratio 2010) and "A Metadescriptivist Theory of Proper Names" (Ratio 2011); a corrected version of the ideas of the last paper is here presented under the title "Outline of a Theory of Proper Names". The best selection of papers in Portuguese is Paisagens Conceituais: Ensaios Filosóficos (Rio de Janeiro: Tempo Brasileiro, 2011).
More developed versions of the papers listed above, among others, were recently published in the book called Lines of Thought: Rethinking Philosophical Assumptions (Cambridge Scholars Publishing, 2014). Personally, I find this book exceptional in its methodology and relevance. But I have found my attempts to convince others of the obvious truth of some ideas opposed to the mainstream philosophy disappointing.
My present research is an attempt to reestablish the internalist and cognitivist-descriptivist tradition concerning theories of reference. I believe that this is possible if we develop these theories in a sufficiently sophisticated form, able to answer the important challenges presented mainly by Kripke, Putnam and Kaplan. Moreover, I believe that contemporary philosophy of language has challenged our commonsensical intuitions too much. This is why I would like to reestablish some old plausibilities and show how they can be linked together in a more sistematic way.
