He has been editor of BBS (Bochumer Beitr ge zur Semiotik) and BPX (Bochum Publications in Evolutionary Cultural Semiotics). His main interests are Semiotics, Cultural Semiotics, Theory of Literature and Poetry, Systems Theory, a General Theory of Evolution, Systems Philosophy. Among his publications: Varia Semiotica (Hildesheim: Olms, 1971), Poetry and Science (T bingen: Narr, 1983), Evolutionary Cultural Semiotics (Bochum: Universit tsverlag, 1986), The Biology of Literature (Bochum: Universit tsverlag, 1993), The Roots of Literature (Bochum: Universit tsverlag, 1993), ed. with Gabriel Altmann: Systems: New Paradigms for the Human Sciences (Berlin: de Gruyter, 1997). The present book is a collection of three essays which - though conceived for different con texts combine in the effort of suggesting an overall and crucial import ance of ICONICITY to the explanation of the evolution of LAN GUAGE in especial, and also of INFORMATION in general. This radical thesis is in conflict with main stream theories of linguistics. ICONICITY as understood in the present book is con sidered to be a foundation-stone for any attempt at a holistic repres entation of communication systems and also of the universe at large. This means that our seeming ly conventional language ultimately relies on various types of iconic imagination. Among the billion different words that have been 'in vented' on this planet, there are only very few, if any, that have been completely arbitrary from the very start.
