The contributions to the collection 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 emerged, some sixty years after Bertalanffy's seminal work on General System Theory, as a bridge-building metatheory between the sciences and religion. 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, including 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 (A. Locker).
