An interesting and intriguing exploration of various fields of effort and kinds of relationships into which theologians of today are entering or might with profit enter- such is the nature of this book. The author opens with two chapters on Theology as Conversation first with the Arts and then with Sciences and Philosophy. The first chapter is full of pregnant suggestions as to how modern theology and modern art might be mutually helpful, a line of thought in which Paul Tillich has been interested. One might wish that his author or someone like- minded would do a treatise on ""Conversation of modern theologians with the people in the pew"". It often seems that theologians are talking to each other, interpreting themselves to other theologians, and on an ecumenical level meeting with other theologians. If theology is to be an invitation -- as the author maintains- theology should tell the people of the churches, in language that they can understand, what it is all about. This particular author does not seem to take himself or his profession so seriously that he is lacking in perspective or a sense of humor. He should hold conversation with laymen.
