Abstract
This book is a comprehensive overview of the theoretical discussion of one of most important conceptions in sociology at the end of 20th century - the theory of social systems. The spotlight of this book falls on the work of Niklas Luhmann and his holistic approach.
Current modern society is, for Luhmann, a functionally differentiated society, which means that a number of specialized societal sub-systems (politics, economics, religion, law, science, art etc) have formed. Each system is based on its own type of communication led by its own generalized communicative media.
