  Chile shows a certain isolation. Until the coup d’état in 1973, developments were limited to formal logic by Juan Rivano, Gerold Stahl, and Rolando Chuaqui. Roberto Torretti, who was exiled to Puerto Rico, stands out. He made an early impact with a well-regarded book on Kant published in 1967. These historical studies led to more systematic studies in the field of philosophy of science and history of geometry, published in the 1990s. Alfonso Gómez Lobo took the opposite path as he first published Siete escritos sobre lógica y semántica in 1972 before leaving analytic philosophy to engage with ancient philosophy when he was exiled to the United States. In the 1990s there were only a couple of figures working on philosophy of mind and language in  Chile.[40] In the twenty-first century the analytic tradition grows, mostly due to the many philosophers who returned to their country after studies  abroad.[41] The Sociedad Chilena de Filosofía Analítica was founded around 2008.
