Unser modernes Wissen gleicht Inseln im Ozean der Unbestimmtheit. An seinen undefinierten Randern vagabundieren Unsicherheit, Indeterminiertheit, Vagheit und Unentschiedenheit. Der Autor referiert an detaillierten Beispielen die neuesten Forschungen zu komplexen Systemen und schlagt Brucken von den Naturwissenschaften zur Philosophie. Erst wenn die enormen Fortschritte und die noch unverstandenen Grenzgebiete, das Bestimmte und das Unbestimmte, zusammen gesehen werden, kann sich unser Wissen uber Fachgrenzen hinaus entfalten. Spezielle Methoden dazu aus der Informationstheorie, Hermeneutik und Zeichentheorie werden dargestellt.

This book explores the limits of our knowledge. The author shows how uncertainty and indefiniteness not only define the borders confining our understanding, but how they feed into the process of discovery and help to push back these borders. Starting with physics the author collects examples from economics, neurophysiology, history, ecology and philosophy. The first part shows how information helps to reduce indefiniteness. Understanding rests on our ability to find the right context, in which we localize a problem as a point in a network of connections. New elements must be combined with the old parts of the existing complex knowledge system, in order to profit maximally from the information. An attempt is made to quantify the value of information by its ability to reduce indefiniteness. The second part explains how to handle indefiniteness with methods from fuzzy logic, decision theory, hermeneutics and semiotics. It is not sufficient that the new element appears in an experiment, one also has to find a theoretical reason for its existence. Indefiniteness becomes an engine of science, which gives rise to new ideas..
