 Activity in Peru started early in the 1950s, as attested by gatherings organized at Universidad Nacional Mayor de San Marcos (UNMSM, Peru’s oldest university) and Sociedad Peruana de Filosofía, both in Lima. Broad interest is also reflected in articles published in the 1950s and 1960s in the weekly literary supplement of “El Comercio” by Oscar Miró-Quesada, Francisco Miró-Quesada, and other intellectuals interested in logic, science, and mathematics. Francisco Miró-Quesada, the country’s leading philosopher, was one of the pioneers in the development of modern philosophical logic and science studies in Latin America, where he has indefatigably encouraged hope in the power of human reason. Miró-Quesada taught at UNMSM for more than two decades, and then at Universidad Cayetano Heredia (UPCH) and other centers in the country. He also headed institutes for philosophical research, first at Universidad de Lima and subsequently at Universidad Ricardo Palma. Miró-Quesada was the author of numerous works in the area of philosophy of science, including a book in the philosophy of mathematics, Filosofía de las Matemáticas (1954). He has also been a champion of research in logic in the region (it was Miró-Quesada who suggested to name Newton da Costa’s approach “paraconsistent logic”, which he helped to promote). Miró-Quesada’s most heartfelt project focused on the study of human reason, regarded as the capacity to reach truth, broadly understood, as outlined in his preliminary book Apuntes para una Teoría de la Razón (1962), followed in 2013 by Esquema de una Teoría de la Razón, in which Miró-Quesada discusses the pursuit of rational validity in logic, science, metaphysics, and ethical theory. In the early 1970s, young faculty trained in Europe and the United States expanded and updated the philosophical study of science in the country, particularly at UNMSM. Timely contributions were made, especially by Luis Piscoya (philosophy of psychology and general philosophy of science), Juan Abugattas (philosophy of science), Julio-Cesar Sanz-Elguera (philosophy of science), and David Sobrevilla (philosophy of the social sciences). Ever since, at San Marcos, Luís Piscoya has been working on the interface between philosophy of science and education; he is the author of Investigación Científica y Educacional: un Enfoque Epistemológico (1995), and numerous papers (e.g., Piscoya, 1993). In the late 1970s, an innovative program in philosophy opened at UPCH, one of the leading research universities in the subcontinent. Under Francisco Miró-Quesada, many international workshops, seminars, and courses took place in Lima as part of this venture. From the late 1980s on, activity at UPCH continued through a program named “Scientific Thought”, headed by Alberto Cordero, with the collaboration of Sandro D’Onofrio and other faculty members.
