Process metaphysics is frequently minimized or dismissed as a result of a failure to grasp its genuine significance. Developments of the last several centuries in philosophy, science, and physics fostered a revolution in metaphysics. This book surveys the reasons for process philosophy and theology, its genesis and historical development. It considers Alfred Whitehead's metaphysics and Charles Hartshorne's and others' treatment of process theology.

The One, the Many, and the Trinity analyzes perhaps the most ambitious and robust system of process thought developed from a Roman Catholic perspective, that of Joseph A. Bracken, S.J. Bracken brings together traditional christian Trinitarian theism with process thought, while integrating into a fundamentally Whiteheadian metaphysics a litany of diverse sources, including Aristotelianism, Thomism, German Idealism, Anglo-American Idealism, social theory, existentialism, postmodern thought, and contemporary philosophy of science. The book goes on to examine Bracken's process response to the problem of the one and many from a more traditional Catholic philosophical and theological perspective.
