'These lectures, published here in English for the first time, show Luhmann at the height of his powers. They offer a unique insight into the engine room of arguably the world's most famous systems theorist. It is indeed a brilliant mind that is at work here; very few other social scientists would be able to perform at such a level. Particularly for students and readers who are not familiar with Luhmann's style of thought, this is an ideal introduction to systems theory by the man himself.'Andreas Hess, University College Dublin'Niklas Luhmann is the closest the social sciences have come, in a long time, to an actual thinker. This book is an indispensable introduction to Luhmann’s unique version of systems theory and required reading to all concerned about theoretical sociology. It offers a rare glimpse into the experimental workings of an extraordinary sociological mind at work.'Stephan Fuchs, University of Virginia
