Karl-Otto Apel has often been associated with Jurgen Habermas and, together, they have been considered to be the main representatives of critical theory. Although not entirely inaccurate, this characterization does not do justice to Apel's specific project and it seems to have somewhat hampered the reception of his thought in the United States. The publication of two volumes of selected essays by the Humanities Press, edited by Eduardo Mendieta (Apel 1994, Apel 1996) as (Apel 1998) should contribute to the dissemination of his original theses and commentaries. In 1973, Apel published a collection of articles and papers under the general title Transformation der Philosophie (Apel 1973). The first volume, subtitled Sprachanalytik, Semiotik, Hermneutik, is dedicated to a discussion of how contemporary philosophy has been transformed by the emphasis put on language. The second volume, with the subtitle Das Apriori der Kommunikastionsgemeinschaft more specifically presents Apel's own transformationof philosophy by claiming for language analysis the status of a first philosophy as a foundation for any rational human enterprise.
