 José Gaos wrote the majority of his published material in Mexico, and he is remembered, above all, for his extraordinary influence as a professor and mentor. For his own part, Gaos defended a radical version of perspectivism: for Gaos, philosophy is a personal confession, so no philosophy is better or worse than another since each is, in the end, the expression of an individual. His most important works are: Del hombre (1970) and De la filosofía (1962). His research in the history of ideas in Mexico and Latin America were also extremely influential. His ideas on how to teach philosophy were included in the curricula of several departments of philosophy throughout the country. Among his students were some of the most important philosophers of the second half of the 20th century.
