Philosophy of Organism
Process, Reality & the Philosophy of Organism
1861 – 1947
Mathematician • Logician • Metaphysician
Born in Ramsgate, Kent in 1861. Entered Trinity College Cambridge in 1880, where he became a distinguished mathematician. Elected Fellow in 1884. His early work centred on universal algebra and the foundations of mathematics. He married Evelyn Wade in 1891.
From 1903 to 1913, Whitehead collaborated with his former student Bertrand Russell on Principia Mathematica, one of the most monumental works in the history of logic — an attempt to derive all mathematics from pure logic. The collaboration was intense and transformative for both men.
Moving to London and Imperial College in 1910, Whitehead turned from pure mathematics to the philosophy of science and nature, producing An Enquiry Concerning the Principles of Natural Knowledge (1919) and The Concept of Nature (1920).
In 1924, at the remarkable age of 63, Whitehead accepted a chair at Harvard and began developing his process philosophy — one of the most ambitious metaphysical systems since Leibniz. Process and Reality (1929) stands as his magnum opus.
The great error of modern thought: mistaking abstractions for concrete realities. We take our models, categories, and simplifications and treat them as if they were the actual texture of the world. The map is confused with the territory.
The fundamental units of reality are not substances but events — momentary occasions of experience. Whitehead calls them "drops of experience, complex and interdependent."
Reality is not made of enduring "stuff" but of momentary events — each occasion comes into being, achieves its experience, and perishes, contributing to the next.
Each actual occasion is a subject that experiences — even at the most basic physical level. Experience is not limited to consciousness but is the basic character of reality.
No occasion exists in isolation. Each arises from its prehensions of the past and contributes to the future. Reality is a web of mutual implication.
Reality is fundamentally process, not substance. Creativity is the ultimate category — the universal of universals, the principle of novelty by which the many become one and are increased by one.
How each actual occasion "feels" or grasps other occasions. Prehension is Whitehead's term for the basic mode of relatedness: every entity takes account of every other. It is pre-cognitive, pre-conscious feeling.
Whitehead's powerful rejection of the split between primary qualities (extension, mass — supposedly "objective") and secondary qualities (colour, warmth — supposedly "subjective"). This bifurcation, inherited from Galileo, Descartes, and Locke, tears nature in two.
This critique anticipates McGilchrist's argument that left-hemisphere thinking strips away the lived qualities of the world, leaving only a mechanical skeleton.
The realm of pure potentials — like Platonic forms but participatory, not static. Eternal objects are the "how" of actuality: they ingress into actual occasions, determining their character. A shade of blue, a mathematical ratio, the quality of joy.
Unlike Plato's static, transcendent Forms, eternal objects are potentials for actuality. They have no agency or existence apart from their ingression into occasions. They are lures, not rulers.
Eternal objects are ordered by God's primordial nature — the conceptual valuation of all possibilities. God's primordial vision provides the "initial aim" for each actual occasion, luring it toward particular potentials.
God as the principle of concretion: not a cosmic ruler but the ground of possibility and a fellow-sufferer who understands. God has a dipolar nature — primordial and consequent.
Nature is better understood as organism than as machine. Every entity has both a physical pole (reception of the past) and a mental pole (conceptual valuation, however minimal). Mechanism is an abstraction from the organic reality.
Whitehead's speculative philosophy in Process and Reality is built on a rigorous categorical scheme — a set of fundamental categories meant to be applicable to all experience.
Creativity, Many, One. Creativity is the ultimate principle by which the many disjunctive entities of the universe become one new conjunctive entity. It is the principle of novelty itself.
Actual entities, prehensions, nexus, subjective forms, eternal objects, propositions, multiplicities, contrasts. These are the basic types of things that exist.
Twenty-seven principles explaining how the categories of existence relate. Including: every condition to which process is subject can be found in the constitution of some actual entity.
Nine obligations governing the process of concrescence. Including the Category of Subjective Unity, Subjective Harmony, and the key Category of Freedom and Determination.
Whitehead saw himself as completing Plato's project. The eternal objects echo the Forms; the Receptacle of the Timaeus prefigures creativity. "A series of footnotes to Plato."
The monads anticipate actual occasions; both are "windowless" experiential units. But Whitehead rejects the pre-established harmony — occasions genuinely feel each other through prehension.
Whitehead admired Locke's empiricism and concept of "power." He saw himself as reforming Locke's philosophy of experience by removing the bifurcation between primary and secondary qualities.
Radical empiricism — the insistence that relations are as real as the things related — deeply influenced Whitehead. James's "stream of consciousness" anticipates the processual nature of experience.
Duration, creative evolution, the critique of spatialising time. Bergson's philosophy of becoming strongly resonates with Whitehead, though Whitehead sought more systematic rigour.
Collaborated on Principia Mathematica, then diverged dramatically. Russell moved toward logical atomism and reductionism; Whitehead toward organismic holism. A telling parting of ways.
Charles Hartshorne and John B. Cobb Jr. developed Whitehead's dipolar God into a full theological programme. God as persuasive rather than coercive; the world's suffering felt by God.
The "fallacy of misplaced concreteness" is central to McGilchrist's thesis in The Master and His Emissary: left-hemisphere dominance mistakes its own abstractions for the living whole. Whitehead is one of McGilchrist's key allies.
Gilles Deleuze drew heavily on Whitehead's concepts of events, prehension, and eternal objects. The Fold explicitly engages Whitehead alongside Leibniz. Process ontology became central to Deleuze's philosophy of difference.
Whitehead's organismic philosophy — where every entity is internally related to its environment — anticipates deep ecology and systems thinking. Nature is not a machine to be exploited but a community of experience.
Though working independently, both Whitehead and Heidegger critiqued the technological-mechanistic worldview. Both rejected substance ontology. Heidegger's "Being" and Whitehead's "Creativity" are strikingly parallel.
Whitehead's critique of reductive modernism — that we lose the lived, qualitative world in mechanistic abstraction — resonates with Scruton's defence of the beauty and meaning that instrumental reason strips away.
The monumental attempt to derive all of mathematics from pure logic. Three volumes of extraordinary rigour. It took 362 pages to prove that 1+1=2. One of the foundational texts of modern logic, even as Gödel later showed its inherent limitations.
Whitehead's first major philosophical work at Harvard. A sweeping history of the rise of scientific materialism and its philosophical inadequacies. Introduces the "fallacy of misplaced concreteness" and argues for an organic philosophy of nature.
His magnum opus, subtitled An Essay in Cosmology. Presents the full categorical scheme of his philosophy of organism. Notoriously difficult but astonishingly comprehensive — one of the most ambitious metaphysical works since Leibniz's Monadology.
The most accessible of Whitehead's later works. Traces the role of ideas in civilisational development. Contains his mature reflections on beauty, truth, art, peace, and the "adventure" of ideas through history.
His final major work, distilled from lectures. More personal and aphoristic than Process and Reality. Contains some of his most quotable and penetrating insights into the nature of experience, importance, and the task of philosophy. "The use of philosophy is to maintain an active novelty of fundamental ideas illuminating the social system."
