 Ortega perceived in his perspectivist mode of apprehending reality a philosophical analogue to Einstein’s physics and, subsequently, invited a comparison of his philosophy of perspectivism to Einstein’s Special Theory of Relativity. Ortega’s essay on “The Historical Significance of Einstein’s Theory” pointed to parallel tendencies in new modes of twentieth century thinking and in Einstein’s theory of relativity, which he characterized as “the most important intellectual fact that the present can show” (Obras, III: 231). In dissolving the entire edifice of classical mechanics, Einstein’s theory ushered in the twentieth century (the “present time”) very much in the manner that Descartes’ philosophy prepared thought for the modern era (Obras, III: 231–34). Ortega’s ideas on the historical significance of relativity were derived primarily from Einstein’s discussion of the Special Theory. He was drawn to comparing the theory of relativity to his philosophy of “perspectivism” because relativity appeared to furnish scientific “proof” of his own “perspectivist truths”, which were formulated in El Espectador in 1916 (Obras, III: 235; see also II: 15–21).
