  Aside from the logical tradition, the rest of Brazilian analytic philosophy emerges not as a sequel of positivism, but as a philosophical innovation. The first publications in the area appeared in the 70s. In Brazil, unlike in Mexico and Argentina, early analytic works did not come from the phenomenological tradition, but from scholars in the history of philosophy. Indeed, there are two major figures in this story, who worked on the history of philosophy but had analytic students: João Paulo Monteiro (a scholar of Hume, interested in questions of epistemology, skepticism, and philosophy of science) and Oswaldo Porchat (a scholar of Aristotle, focused on skepticism but also interested in logic, philosophy of language, and sciences). In 1976, Porchat founded the Centro de lógica, epistemología e história da ciência (CLE) at the University of Campinas, São Paulo, and the following year he  began to edit the journal Manuscrito, edited by M. Wrigley and later by M.   Ruffino.[30]
