Sur [South] magazine, founded and financed by Victoria Ocampo (1890-1979), was one of the major literary journals in Argentina. It was published from 1931 until 1988, though on a sometimes irregular basis. The original group of contributors included writers such as Jorge Luis Borges (1899-1986) and Norah Borges (1901-98), Guillermo de Torre (1900-1971), Oliverio Girondo (1890-1967), Leopoldo Marechal (1900-70), Adolfo Bioy Casares (1914-99), and Silvina Ocampo (1903-1994), among others.Julio E. Payró (1899-1971) was an Argentine painter, essayist, and art critic; he was the son of Roberto Jorge Payró, the journalist and playwright. Concerned about the development of the visual arts, he initially helped found the Fondo Nacional de las Artes [National Fund for the Arts] and then, within the field of higher learning, encouraged the study of the History of Art at the Facultad de Filosofía y Letras [Arts Faculty] at the University of Buenos Aires. This article has been chosen because it documents Payró’s opinions concerning the precise naming of and distinction between Abstract, Concrete, Non-figurative, and Non-objective art. His thoughts are clearly expressed in an "Open Letter" to Torre which was published and replied to in Sur magazine, issue # 202, August 1951. Following that exchange of letters, the magazine organized a survey based on the following questions: 1. Do you firmly believe that the term Abstract art, which has been widely used until now, is improper and imprecise, and should now be replaced by the term Non-figurative art, but with the option of including, under the umbrella of this term, other names that might be used to identify more specific tendencies? 2. If not, what name would you suggest, based on the exactness of its meaning and its chances of widespread acceptance? 3. In your opinion, what is the meaning and the future of Non-figurative art as related to Representative art? In Buenos Aires, the survey was answered by Cayetano Córdoba Iturburu (1899-1977), Manuel Mujica Láinez (1910-84), Gyula Kosice (1924–2016), Juan Del Prete (1897-87), and Tomás Maldonado (1922). Some foreigners also responded: Mathias Goeritz (1915-90), Hans Platschek (1923-2000), Vicente Martín (1911-1998), Ricardo Gullón (1908-91), Eduardo Westerdhal (1902-83), and Ángel Ferrant (1890-1961). The links to foreign artists were, to some extent, due to the friendship between Ángel Ferrant and Guillermo de Torre, but were also a result of their cultural activities at the Escuela de Altamira [School of Altamira] in Santillana del Mar, Spain. This document is related to the replies to the debate over the exact name for Abstract, Concrete, Non-figurative, and Non-objective art which can be found in records as follows: Abstract art or Non-objective art? : [‘Abstract art’ is and is not an adequate term] (# 757530), Abstract art or Non-objective art? : [Do we add anything to painting if we say Abstract art or Non-figurative art?] ( # 757649), Abstract art or Non-objective art?: [At the opening session of the first meeting of the "Escuela de Altamira"] (# 757489), Abstract art or Non-objective art? : [In his detailed "Reply to Julio E.
