A Systems Theory of Religion, still unfinished at Niklas Luhmann's death in 1998, was first published in German two years later thanks to the editorial work of Andr? Kieserling. One of Luhmann's most important projects, it exemplifies his later work while redefining the subject matter of the sociology of religion.

It provides us with a fresh vocabulary and a fresh philosophical and sociological approach to one of society's most fundamental phenomena.Niklas Luhmann (1927-1998), Professor of Sociology at the University of Bielefeld, was one of the most eminent social theorists of the last decades of the twentieth century.
