(Barcelona, 1942-2013) studied Philosophy in Spain and Germany and was Professor of Philosophy in the Faculty of Humanities at the University Pompeu Fabra. He reported his thought through multiple trials, among which include Drama and identity (1973), Treaty of Passion (1978), The beautiful and sinister (National Essay Prize 1983), The Limits of the World (1985) City to City (2001) and the trilogy that form the boundary Logic (1991), The Age of the Spirit (City of Barcelona 1995 prize) and the right border (1999). He held a deep reflection on the human condition, man as an inhabitant of the limit, in that border area between being and nothingness from which it derived its relationship with the divine, with the sacred and transcendent that made him a mestizo be different, the "philosopher limit." Eugenio Trias was one of the most prestigious and internationally renowned Spanish philosophers, as evidenced by the fact that, in 1995, was the first Spanish philosopher Friedrich Nietzsche awarded the International Prize. In Spain, he received numerous awards and was honorary doctorate by several universities, including the Autonomous University of Madrid.
