  A number of mathematicians and physicists interested in the foundations of mathematics and the natural sciences introduced the logical developments of the early twentieth century and the ideas of the logical positivists of the Vienna Circle. Mario Bunge, who in 1944 founded Minerva, the first philosophy journal in the country, played an important role. Bunge was also the author of the first analytic book written in Latin America, Causality: The Place of the Causal Principle in Modern Science, published by Harvard in 1959, which was subsequently translated into Spanish. The next year he published Antología Semántica, the first Spanish translations of Russell, Carnap, Hempel, Tarski, Quine and Goodman. However, Bunge moved to Canada shortly afterwards and left no students in Argentina. Contemporaneous with Bunge, Julio Rey Pastor and Gregorio Klimovsky introduced issues in logic and the foundations of mathematics at the Faculty of Exact Sciences of the University of Buenos Aires. Though he published few papers, Gregorio Klimovsky fostered the development of analytic philosophy in Argentina. His deep knowledge and enthusiasm for the foundations of mathematics, methodology of natural sciences, the foundations of psychoanalysis and the history of science left a deep impression on his students. Klimovsky taught logic and philosophy of science at the University of Buenos Aires from 1957 to 1966, introducing contemporary logic and analytic authors to philosophy students, some of whom became the first generation of Argentine analytic philosophers.
