  In Guatemala, Hector-Neri Castañeda (who later emigrated to the United States) published several papers on consciousness and normative logic in the late 1950s and on the private language argument in the early 1960s. From his workplace in the United States (Indiana University) he collaborated with PhD students from Costa Rica, Guatemala, and Mexico. Similarly, other Latin American philosophers emigrated to the United States; a paradigmatic case is Ernesto Sosa, a Cuban-born philosopher who studied and worked all his life in the United States who constantly sought to establish links with philosophy in Spanish, especially the analytic philosophers of Mexico and Argentina.
