Abstract
In the first third of this century Cassirer was one of the leading, most influential philosophers of the German-speaking world. He was the respected opponent of such giants as Husserl, Russell, Schlick, Heidegger or Carnap who left their mark on the philosophical landscape until this very day. One might recall his discussion with Schlick on the philosophical relevance of Einstein’s relativity theory in the first decade of this century. Carnap reported to have received essential ideas for the Logical Construction of the World from Cassirer and other neo-Kantians; or, to recall a more spectacular event concerning Cassirer’s philosophy, one might mention the famous “Davos disputation” with Heidegger in 1929 which seems to have been a major philosophical event for the audience
