The dominant metaphysical system in America this century has been process philosophy, of which the most prolific and persuasive advocate has been Charles Hartshorne. Traditional Christian thinkers, however, have consistently viewed this philosophy, and Hartshorne's thought in particular, as fundamentally incompatible with trinitarian theism. In this compelling work, Dr. Boyd moves beyond this impasse. Utilizing exhaustive research and critical acumen, he maintains that a reworked version of Hartshorne's process system actually provides the metaphysical grounding of trinitarian thought, at the same time preserving the advantages that have made process philosophy an attractive alternative to traditional Western substance ontology. The result is a remarkably creative trinitarian process metaphysics that provides a new perspective on both process thought and the traditional doctrine of the Trinity.
