  Philosophy of language was introduced as a discipline in Argentina by Thomas Moro Simpson who published Formas lógicas, realidad y significado in 1964, a book of Latin American analytic literature, influential not only in Argentina and Mexico (where he traveled in 1967 to teach on these topics), but also in other Latin American countries. Simpson also published Semántica Filosófica in 1973, a book which includes translations of some of the most foundational works in analytic philosophy—such as Russell’s “On Denoting” and Frege’s “Sense and Reference”—in addition to discussions related to quantification, existence and belief  attribution.[3] His students, Raúl Orayen and Alberto Moretti, worked specifically on logic, the philosophy of logic and philosophy of language. Moretti specialized in Frege and also studied Davidson’s philosophy of language and Tarski’s theory of truth. Some of his most significant contributions have recently been compiled in Interpretar y referir. Ejercicios de análisis filosófico (2008). Orayen worked in Argentina until the 1970s when he emigrated to Mexico, where he joined the IIF-UNAM. There he fostered several generations of analytic philosophers and made his most substantive contributions including one of his most significant works, Lógica, significado y ontología. His  research[4] focused on the philosophy of logic and language, including the work of Russell, Frege, Quine, Kripke, and  others.[5]
