Kleine Geschichte des Konstruktivismus

Abstract

The article provides a series of hints on constructivist thinkers pnor to the emergence of „radical constructivism", starting with the Presocratics and progressing via Vico, Berkeley, Kant or Vaihinger and others. Following this the author investigates such core constructivist notions of „knowledge" and ,,environment" and concludes with a plea for an „ontological agnosticism" which, in more than one way, leads back to the beginning of the article, namely to the presocratic schools of thought.
