From an interdisciplinary perspective, this anthology is dedicated to both the phenomenon and the concept of ambiguity in the ambiguous field between society, science and religion. It attempts to stimulate the study of ambiguity and tolerance of ambiguity as a characteristic and challenge for social differentiation processes. Expertise from psychology, philosophy, sociology, linguistics and the historical sciences serves to make the concept of ambiguity attractive and fruitful for the systematic and ethical subjects of theology and simultaneously shows its broader relevance for social frameworks. It becomes clear that society, science and religion can best do justice to the complexity of life when they resist the lure of unambiguous answers. Thus, the authors of this volume agree that the answers to the question of a successful social coexistence are definitely ambiguous.
