 The Hyperion Group was a group of young philosophers from the National Autonomous University of Mexico that included Leopoldo Zea (1912–2006), Jorge Portilla (1918–1963), Ricardo Guerra (1928–2007), Emilio Uranga (1921–1988), and Luis Villoro (1922–2014). It was active between 1948 and 1952, and its purpose was to employ the categories of existentialism to analyze Mexico and Mexican being, an analysis that was meant to reveal the reality of Mexico and Mexican being and encourage Mexicans to transform their reality.
