  In addition, a large group of philosophers of science work at the Federal University of Santa Catarina (Florianópolis) organized around the Núcleo de Epistemologia e Lógica (NEL) which edits the journal Principia. Every two years they organize an international symposium on topics of philosophy of science, epistemology, logic, and metaphysics. The group includes Newton da Costa, Décio Krause, Luiz Henrique de A. Dutra, and two Argentine emigrants, Alberto Cupani and Gustavo Caponi.
