Process and Reality: An Essay in Cosmology: Summary & Key Insights

My speculative scheme begins with a reformation of metaphysical categories. Instead of substances, I posit 'actual entities' or 'actual occasions.' These are the ultimate realities—events of experience that compose the world. An actual entity is not a piece of matter but a moment of becoming, a dynamic synthesis of relations that, once completed, perishes into the past while contributing to future occasions.

Each actual occasion feels or 'prehends' others. Prehension is my term for the way entities receive and integrate the world’s influences into their own internal experience. The universe, therefore, is a vast network of mutual prehensions. Nothing exists in isolation; every entity is defined by its relations. This replaces the bifurcation of nature that has long divided mind and matter.

Next comes the notion of 'nexus,' the togetherness of actual entities. Every society of entities constitutes ordered patterns—such as living organisms, planets, or communities—where processes are interwoven to sustain continuity. Through this speculative scheme, I lay the groundwork for a metaphysical picture in which the world is a self-creating totality, not a collection of inert parts.

The speculative scheme is a framework for explanation, not a final dogma. It is an imaginative construction meant to harmonize with experience and science, open to revision, but committed to coherence. For metaphysics must strive to interpret the general character of existence, not to dictate its particulars. Thus, these categories of entity, nexus, and prehension establish the foundation upon which the rest of my cosmology is built.

In constructing the categoreal scheme, I attempt a systematic articulation of the conditions necessary for any actual occasion. These are not arbitrary definitions but principles inferred from the analysis of experience itself. The categories of existence describe what there is; those of explanation clarify how what exists comes to be. Categories of obligation point to value and purpose, showing that metaphysical order is not value-free.

A key principle here is 'the Category of the Ultimate': creativity, permanence, and change. Creativity is the universal of universals, the activity through which actual entities emerge and perish, while many become one, and are increased by one. This creative advance drives the world forward—not chaotic, but ordered through permanent principles. Thus, beneath flux there is pattern, and through pattern there is renewal.

These categories build an architecture of intelligibility, allowing us to see reality as structured yet fluid. Metaphysical certainty yields to metaphysical adventure: an orderly openness that reflects both stability and transformation. Here, value enters metaphysics, for no process of becoming is neutral—it aims toward satisfaction. Existence, at every level, is an achievement of harmony amid contrasts, the resolution of complexity into worth.
