Process philosophy
The philosophical tradition that takes becoming as primary over being, events over substances, process over permanence. Where the mainstream Western tradition from Parmenides onward sought the unchanging behind the changing, process philosophy argues that change is not appearance — it is reality. What endures is not a thing but a pattern of activity.
The core move
Replace substance with process. An entity is not a thing that undergoes change — it is a pattern of events that achieves temporary stability. What we call an object is a regularity in the flow, not a foundation beneath it. The question is not “what is it made of?” but “what is it doing?”
The tradition
Heraclitus — the historical anchor. “Everything flows.” Reality is flux, held together by logos. The unity of opposites — the way up and the way down are the same. The earliest Western formulation of becoming as primary.
Hegel made process the engine of thought. The dialectic — every determination generating its own negation, resolved through sublation — drives thought, history, and reality through stages of increasing concreteness. Nothing is simply negated; everything is preserved and elevated. Whether Hegel belongs to process philosophy or to systematic idealism is itself contested — his process is teleological, aiming at absolute knowing, which sits uneasily alongside the open-ended becoming of the later tradition.
Bergson made duration the starting point. Lived time is continuous, qualitative, indivisible — not the spatialised time of clocks. Creative evolution produces genuine novelty — not the rearrangement of pre-existing elements but the emergence of what could not have been predicted. The élan vital drives life through matter, splitting into divergent lines. Russell and others charged the concept with vagueness — a vitalistic placeholder rather than an explanation.
William James — radical empiricism, the stream of consciousness, the “pluriverse.” Experience is primary, not the objects abstracted from it. James directly influenced Whitehead; his pluralism and his insistence on the reality of relations are ancestral to the process-relational line.
Whitehead built the fully systematic version. Reality consists of actual occasions — moments of experience that arise through concrescence, achieve satisfaction, and perish as data for future occasions. Creativity is the ultimate category: the many become one and are increased by one. Nothing exists in isolation — every entity is constituted by its relations. The philosophy of organism is the Whitehead-specific programme with its own apparatus and tradition.
Peirce — process-pragmatist. Semiosis as process: the sign-interpretant chain is structurally unlimited, each interpretation creating a new sign. His categories (Firstness, Secondness, Thirdness) articulate modes of being that are processual rather than static. Often grouped with the tradition though he precedes Whitehead by a generation.
Dewey — experience as transactional. Knowing is not a spectator relation but an active engagement between organism and environment. Inquiry is a process of transforming an indeterminate situation into a settled one.
Strands and traditions
Process theology. Charles Hartshorne developed Whitehead’s God concept into dipolar theism. John B. Cobb Jr. institutionalised process theology at Claremont. The Center for Process Studies (founded 1973) remains the institutional home. Process theology kept the corpus in print through the mid-twentieth century when mainstream analytic philosophy had largely set it aside.
The continental process-relational revival. Deleuze reads Bergson and develops difference-and-repetition as process metaphysics; The Fold (1988) claims Whitehead explicitly. Stengers carries Whitehead forward through cosmopolitics and the ecology of practices. Latour’s actor-network theory has process-relational commitments — actants constituted in networks, not prior to them. Haraway’s sympoiesis and string figures draw on the same well.
Connection to phenomenology. Merleau-Ponty’s flesh as processual — the body not as thing but as ongoing engagement with the world. The enactivist tradition (Varela, Thompson) extends this into cognitive science.
Contestations
The substance-process debate remains live in analytic ontology — whether process metaphysics can account for persistence and identity without smuggling substance back in. Whitehead’s eternal objects and God are the most contested features of the systematic version: Platonist residue or necessary apparatus? Bergson’s élan vital attracted charges of vitalistic vagueness from Russell and others. Hegel’s place is itself disputed — systematic idealist or process thinker?
What holds the tradition together
Process thinkers share the conviction that static categories distort reality. Substance, attribute, fixed essence — these are abstractions drawn from a world that is fundamentally in motion. To understand anything is to understand its history, its relations, and its becoming. Permanence is real, but it is the permanence of pattern, not of stuff.
Where process philosophy stops
The tradition’s three classical figures diverge on what follows from the core move. Hegel’s process reaches absolute knowing; Bergson’s remains intuitive and anti-conceptual; Whitehead’s is systematic and speculative. None of them makes language the medium through which process is lived and shared. Hegel’s spirit develops through history but speaks in one voice. Bergson mistrusts language as spatialisation of duration. Whitehead’s actual occasions prehend each other but do not share a vocabulary. Peirce is the partial exception: signs and interpretants are processual, but his account stays within the logic of representation rather than the shared practice of language.
Reception
Whitehead’s slow uptake in mainstream analytic philosophy through the mid-twentieth century; strong reception in theology through Hartshorne and Cobb; renewed interest from the 1990s through Stengers, Deleuze, and Latour; the ontological turn in anthropology (Viveiros de Castro, Descola) draws on process-relational commitments without always naming the lineage.
