In this publication, the author attempts to develop an aesthetic theory from Heidegger¿s phenomenological concepts. She analyzes Heidegger`s concepts of truth, world, space, and related concepts and establishes a formal, contextual and material method of analysis for the purpose of examining works of art. This new method of analysis is applied to three pieces by the artist Joseph Beuys as a case study.

Eda Keskin has been working for years on phenomenology, art history, and the philosophy of Heidegger. With this work, she has earned the academic prize of the "Luther-Urkunde" of the Martin Luther University Halle-Wittenberg in Germany.
