An elucidation of the general metaphysical principles underlying everything. Whitehead attempts a rigorous and consistent system for explaining how novel actuality enters into the world. He seeks to coordinate metaphysics with the revolutions of both quantum physics and relativity theory, while picking and choosing elements from Eighteenth-Century philosophy. The resulting massive tome has at its heart a vision of a universe in constant re-creation of itself, in which each part uniquely reflects the whole. Reading this, I was both humbled before the workings of so great a mind, and inspired by his unifying and, ultimately, optimistic vision of a world both eternal and ever-renewed.
