 At the outbreak of the First World War, Ortega began to contribute to the “European cultural mission” of Spain through his lectures on some of the major trends within the currents of European thought. Biological thoughts of Hans Driesch, August Weissmann, and Jakob von Uexküll, and the philosophical, economic and social thoughts of Max Scheler, Georg Simmel and Werner Sombart were introduced to Spanish university students for the first time. In July 1916, Ortega, his father and several other Spanish intellectuals departed Spain for Argentina where, between August and October, Ortega gave a series of lectures at the University of Buenos Aires on Kant and the currents in contemporary Continental philosophy. These lectures followed the recent arrival of Julio Rey Pastor, a noted Spanish mathematician, who immigrated to Argentina to elevate the mathematical and scientific level of instruction at the University of Buenos Aires. Ortega’s residence in Buenos Aires kept him away from political affairs, save for an article in June 1917 in which he criticized the role of the military in politics. The political commentary precipitated his definitive departure from El Imparcial and prompted his move with his brother, Eduardo, to join a new daily newspaper El Sol, founded by a close friend, Nicolás María de Urgoiti of La Papelera Española. The first issue appeared on December 1, 1917. Five years later, Ortega also assisted in establishing the publishing house Calpe (later named Espasa-Calpe), which immediately made available Spanish and European classic and contemporary literature in reasonably priced paperback editions. Between these activities, Ortega became the founder and director of the monthly Revista de Occidente, publishing the first issue in July 1923. The Revista, which was directed toward an educated readership, quickly became one of Europe’s renowned intellectual journals. The organ became a veritable “Review of the West” as several of the articles, which were translations of works previously published abroad, were important philosophic and scientific trends representative of “our epoch”: Spengler, Huizinga, Simmel, Uexküll, Brentano, Heimsoeth, Driesch, Pfänder, Müller and Russell. The journal also became the principal medium of the intelligentsia and, in conjunction with Ortega’s tertulias in the offices on the Avenue Pi y Margall, assisted in fostering the poetic generation of young intellectuals, the “Generation of 1927”. The Generation of 1927 originated as a term to characterize a certain similarity of poets and writers in 1920s Spain. The year signaled the moment when intellectuals and students began to resist the dictatorship of General Miguel Primo de Rivera as a prelude to the Second Republic. As with their predecessors, the Generation of 1898, the perceived national crisis created a spirit of collective mentality, or at least a shared identity, in the years preceding the Spanish Civil War. Several of the younger vanguard poets were first published by Índice, founded and directed by Juan Ramón Jiménez Mantecón (1881–1958), a nineteenth-century follower of Karl Christian Friedrich Krause (1781–1832), who had been one of the first to reintroduce modernist themes in Spanish literature. Other members of the Generation of 1927 found expression through the Revista de Occidente. Ortega, whose major works were published in the 1920s, served as one of the most important links between the two generations by giving editorial assistance to the younger poets and addressing The Dehumanization of Art (1925) to their concerns. Along with Américo Castro (1885–1972), Ramón Pérez de Ayala (1880–1962), and Eugenio d’Ors y Rovira (1882–1954), he provided an intellectual leadership that inspired the younger Spaniards to develop fully their own creative endeavors.
