 The philosophical model established in reaction to Positivism blossomed in the 1950s as a result of the activities of the Chilean Society of Philosophy, the regular publication of the Revista de Filosofía, and the internationalization of the philosophical community. The society was recognized by the Inter-American Federation of Philosophical Societies, the Institut International de Philosophie, and the Fedération International des Sociétés de Philosophie. Foreign faculty taught regularly at the major philosophy departments in the country, and in 1956 the first international congress of the Inter-American Society of Philosophy took place in Santiago, featuring such prominent figures as Miguel Reale, Eduardo Nicol, Risieri Frondizi, Francisco Romero, José Gaos and José Ferrater Mora. Presenters in the fields of logic, philosophy of science and theory of knowledge included Willard Van Orman Quine, Roderick Chisholm, Mario Bunge, Francisco Miró Quesada, and Juan David García Bacca. The local philosophical community could celebrate with pride the effectiveness with which the discipline had become a recognized professional endeavor both nationally and internationally.
