Book excerpt: The contributions to the collection Systems Theory and Theology explore the interplay between systems theory, religion and theology, and the symbolic expressions and philosophical foundations of these academic disciplines. This endeavor is rooted in the oeuvre of the late Austrian physicist Alfred Locker (1922-2005), who firmly believed that systems theory would finally emerge, some sixty years after von Bertalanffy's seminal work on General System Theory, as a bridge-building metatheory between the sciences and religion. The essays in this volume show, however, that such conversation transcends the usual form of dialogue among these disciplines. The studies contained in this collection enter into a critical evaluation and reassessment of the dominant postulates of scientific and theological systems and their interaction. Systems Theory and Theology includes treatments of paradoxes (A. Locker), the inner sciences (Zwick), systems of meaning (Krieger), philosophy (Murphy), theology (Sedmak), isomorphies of religious symbols (Zwick), and the bridging of science and religion (M. Locker).
