First Philosophy and Philosophical Progress from Karl–Otto Apel's Perspective

The aim of this article is, first, to show the transformation of First Philosophy from Aristotle to Apel’s transcendental hermeneutics, through Kant’s Transcendental Philosophy and the practical turn during the contemporary age. Secondly, to follow the line of Apel’s transcendental hermeneutics, that constitutes a new paradigm of First Philosophy, founded on the pragmatic and semiotic transformation of philosophy. And, thirdly, to contribute another form of First Philosophy, from the Spanish Philosophy, with the ratiovitalistic hermeneutics (Ortega y Gasset) and/or Noology (Zubiri).
