In this volume, Father Moeller, Herbert Haag, and Gottfried Hasenhuttl contribute meditative essays on the most important--because the most basic--religious crisis of them all: whether God exists, and, if so, whether or not man can know him. The three authors each take different approaches to the question: Moeller considers the Genesis narrative of creation; Haag examines the God-is-dead school of writers; Hasenhuttl interprets the insights of Teilhard de Chardin. The three essays are of uniformly high quality, though one may suspect that a more readable evenness of style and uniformity of terminology might have been achieved had a single translator been entrusted with the entire book. Despite that flaw, The Unknown God? will be a useful addition to the libraries of Catholic college-level institutions. The general reader, however, will find the essays a bit too affective, too ""spiritual,"" for his taste.
