 Sergio Sánchez (Argentina) is an important reference for studies concerning skepticism in the 19th and 20th century. Sánchez (2010) focused on the presence of skepticism in Nietzsche, especially the influence of Sextus and Cicero. In his papers, one important topic is that of Nietzsche’s analysis of belief and its relation to skepticism. In connection with Nietzsche, Kathia Hanza (Peru) (2011) has explored different sides of skepticism. The works of Rogério Lopes (Brazil) (2006, 2012) on Nietzsche and skepticism, very similar in spirit to those of Sánchez and Hanza, also deserve to be mentioned.
