Process metaphysics is by no means a recent philosophical approach to the nature of reality. However, the strength and applicability of this school of thought (or better: schools of thought) has been largely overlooked or under-valued. As a result it is appearing on the scenes of much of Western academia as a little-understood, novel approach to many philosophical issues, both contemporary and ancient. One of the leading reasons for this apparent neglect of influence is the lack of a unifying coherent system to which one could ostensibly identify with process philosophy.
