Luhmann's theory is fascinating and complex. It offers incomparably
enlightening insights, references and research opportunities, but
reveals its utility only after a quite high competence threshold. Using
the reticular form of the glossary, this book makes the theory
accessible while maintaining its complexity. Without being obstructed by
knowledge gaps or by references to concepts presented elsewhere, readers
inside and outside sociology get the required support to explore
sociological systems theory and to engage with it. Luhmann himself, in
his introduction, praises the form of the glossary to cope with the
challenges of the theoretical description of our highly complex society.
