Living in hope, Professor Moltmann points out, is an experiment. Hoping is a risky matter; it can bring disappointment and surprise developments. To live in hope is a mark of the Christian, and is so in every age, so that a theology of hope should not be regarded as a passing fashion. The essays collected in this book are experiments made by Professor Moltmann in conversation with a wider audience. They include the texts of lectures given in America, Asia, Africa and Australasia, as well as in Europe and are marked by the concern of a distinguished theologian that German theology shall learn from other cultures and other movements of thought. Almost all of them were written after 1970 and cover subjects in theology, ethics, philosophy of religion and politics. They also show how the themes of Professor Moltmann's two major books, Theology of Hope and The Crucified God may be applied in practice to the basic issues of our time.
