Since 2006 I am full professor at the Federal University of Ceará (UFC) in Fortaleza, Brasil. I am developing a systematic philosophy based on the concepts of fortuity (meta-metaphysics), chance-event (ontology), consciousness (theory of subjectivity, epistemology, theory of action) and friendship (ethics). Historically, I work on German Idealism (mainly Kant and Hegel) and Aristotle (mainly ethics).
