The author of this volume explores questions of mind, reality, knowledge and signification in a provocative, stimulating and humorous way. Drawing on various domains such as systems research, semiotics, philosophy, and complexity sciences, he touches basic questions of our Being-in-the-World as cognate creatures, and presents a novel theory of the mind as a boundary phenomenon.
