This book provides an introduction to Hartshorne's contributions to contemporary philosophy and theology. It also covers some of the current controversies in philosophy and theology that Hartshorne's contributions have generated. The opening chapter is a lucid and penetrating introduction to Hartshorne's thought. Some of the following chapters break new ground on issues that have concerned Hartshorne throughout his career: the nature and methods of metaphysics, the existence and nature of God, and the place of religion and metaphysics in the modern world. Many chapters survey the current state of controversies on those topics. Other chapters relate Hartshorne's work to other traditions and to trends in contemporary philosophy--to postmodernism, classical Western theism, Indian philosophy, analytical philosophy, and American pragmatism.
