 Perhaps it should also be mentioned some other studies on the history of skepticism. On the one hand, there are some literary studies. Machado de Assis, one of the best Brazilian writers, has been seen as a skeptic by many people. One reason is that Machado read and used extensively Montaigne’s skepticism. José Raimundo de Maia Neto (1994) published a book on the topic. The novelty of his book is that it was the first discussion on Machado’s skepticism based on the history of skepticism. Paulo Roberto Margutti Pinto (2007) and Gustavo Bernardo Krause (2007a) discussed Maia Neto’s interpretation, and Maia Neto replied to them. Krause is a Brazilian novelist as well as a professor of literature who published many books and papers on skepticism and literature (Krause 2004), on Machado (Krause 2006) and other writers such as the well-known Brazilian poet Carlos Drummond de Andrade (Krause 2007b). On the other hand, Paulo Roberto Margutti Pinto has been studying the history of Brazilian philosophy, in which he sees an important role for skepticism long before Porchat brought it to center stage. In Pinto 2010, he argues for the influence of Francisco Sanches on Brazilian colonial thought. One of the reasons for Porchat’s success is that it seems that Brazilian thought has always had, at least in some places, a tendency towards skepticism. Machado de Assis would not be an exception.
