Eugenio Trías Sagnier

After obtaining his bachelor's degree in philosophy at the University of Barcelona in 1964, he continued his studies in Pamplona, Madrid, Bonn and Cologne.

[5] Trias considers himself as an "illuminist exorcist" who exposes philosophical reason to a permanent dialogue with their shadows.

As an alternative to logical positivism, the analytical philosophy or Marxist thought,[6] he extended reason to spheres including irrationality and the madness (Philosophy and carnival); the mythical and magical thought (Methodology of magical thought); passionate love (Treaty on passion); the Sinister (The beauty and the sinister) as a shade of the categories of beauty and the sublime which founded traditional aesthetics; or the world of religions as the shadow of modern Western reason (The age of the Spirit).

The most significant innovation of Trías' philosophy appeared in the early 1980s, when he discussed the concept of limes ("limit").

Trías proposed that being (whose issue has always been the main question for Western philosophy from its origins) may be understood as "being of limit" -- that is, the border area that separates as well as joins the phenomena and the noumena.
