 Beginning in the early 1960s, philosophers began to study analytic philosophy, particularly authors such as Russell, Carnap, Wittgenstein, Strawson, and Quine. At the time, it was claimed that a philosophy inspired by science was required to modernize Mexico, not unlike the positivist turn in the second half of the 19th century. The creation of the journal Crítica in 1967 accelerated the popularity of analytic philosophy in Mexico. At the end of the 1960s, the Institute for Philosophical Research of the National Autonomous University of Mexico became the main center of analytic philosophy in the country and in Latin America. The main promoters of analytic philosophy during that period were Alejandro Rossi (1932–2009), author of Lenguaje y significado (1969), and Fernando Salmerón (1925–1997), who also wrote extensively on the history of Mexican philosophy.
