Lotze’s work entitled „World of Ideas” is the second chapter of the third book of System der Philosophie. Erster Teil. Drei Bücher der Logik (published in 1874). Th is text had an exceptional impact on the development of German philosophy (especially Marburg and Baden School of neo-Kantianism, Husserl’s and Scheler’s phenomenology and Frege’s logic) because of the concept of validity (Geltung) which Lotze had presented here as a foundation of his interpretation of Plato’s theory of ideas.
The journal founded by Leszek Kołakowski, Bronisław Baczko and Jan Garewicz appears continuously since 1957.
