 In 1964 a military coup led to government action eradicating academics suspected of leftist sympathies, seriously disrupting many fields, including philosophy of science. Nevertheless, faculty groups were soon able to restore activity. In 1970, at USP João Paulo Monteiro managed to start Ciência e Filosofia, a journal dedicated to logic and philosophy of science from a plurality of perspectives. Revitalization of the discipline continued throughout the decade with timely research projects, often carried out in conjunction with international visits and courses, notably ones organized by Porchat, first at USP and after 1975 at State University of Campinas (UNICAMP), where he headed a new unit, Centro de Lógica, Epistemologia e História da Ciência (CLE), whose members included Zeljko Loparic and other distinguished scholars. In 1977 CLE launched the prestigious journal Manuscrito, supplemented in 1980 by Cadernos de Filosofia e História da Ciência, and in 1987 by a book series (Coleção CLE). CLE quickly became a symbol of hope for philosophers and historians of science as well as logicians. In particular, CLE is involved in the articulation of “Paraconsistent Logic”, a field Newton C. da Costa began to develop in the late 1950s and early 1960s when he was working at Federal University of Paraná. Da Costa is one of the most charismatic and energetic thinkers in Latin America, a world-class figure in mathematics, logic, and philosophy of science, with a widely recognized reputation for original works on non-classical logics, the axiomatization of scientific theories, and structuralist philosophy of science, orientations that continue to be active in Brazil with such figures as Itala D’Ottaviano and Walter Carnielli.
