The Historical Context of Process Philosophy: Bridging Being and Becoming

Process philosophy is one of the most significant intellectual departures in Western metaphysics – a school of thought that fundamentally rejects the idea that reality is made up of fixed, stable substances, and replaces it with a vision of the world as perpetual process and dynamic change. To understand why this philosophy emerged, and why it was so radical, you need to trace its historical roots: back to ancient Greece, forward through the scientific revolution, and into the early twentieth century when Alfred North Whitehead gave it its most systematic expression. The term Sitz im Leben – German for “setting in life” – captures exactly this: what was the lived historical moment that made process philosophy not just possible, but necessary?

The ancient quarrel: being versus becoming 🔗

The tension at the heart of process philosophy is ancient. Long before Whitehead, Greek philosophers were already locked in a foundational debate about the nature of reality – and the two key figures on opposing sides were Heraclitus and Parmenides.

Heraclitus of Ephesus (fl. c. 500 BCE) is often called the godfather of process philosophy. He held that change is the basic principle of reality – that everything is in flux. He expressed this through the famous claim that you cannot step into the same river twice, because the water is always flowing and renewing itself. For Heraclitus, fire served as the central symbol of the cosmos: always burning, always transforming, never static. His doctrine, often summarized as panta rhei (“everything flows”), was the earliest philosophical attempt to treat change not as a surface-level appearance but as the deepest truth about existence.

Parmenides of Elea took the exact opposite position. In his philosophical poem On Nature, he argued through strict logical deduction that true reality – what he called “Being” – is eternal, uniform, motionless, and changeless. Change, in his view, is merely an illusion generated by the senses. Genuine knowledge concerns only what is permanent. As he framed it, the way of truth reveals a timeless, unchanging reality, while what we perceive through our senses is only appearance.

These two thinkers defined the poles of a debate that would persist for millennia. Plato tried to reconcile them – treating the sensible world of change as less real than the eternal world of Forms. Aristotle offered his own synthesis through the concepts of potentiality and actuality. But the fundamental tension between being and becoming never fully resolved. It was this unresolved tension that process philosophy would later inherit – and attempt to dissolve by giving primacy to becoming.

The dominance of static metaphysics in Western philosophy 🔗

From Plato and Aristotle onward, mainstream Western philosophy developed along broadly substance-based lines. Reality was understood as composed of things – individual substances with stable natures, properties, and identities. Change was important, but it was always change in or of a substance; the substance itself was the foundational category. Whether in medieval Scholasticism, Cartesian dualism, or early modern metaphysics, the basic assumption held: what is most real is what endures, and what endures is what fundamentally is.

This philosophical framework was not merely academic. It aligned conveniently with the emerging worldview of the scientific revolution. René Descartes divided the world into two kinds of substance – thinking things and extended material things. Isaac Newton described a universe governed by fixed, deterministic laws acting on discrete particles of matter in absolute space and time. The universe began to look less like a living organism and more like a vast mechanism – precise, predictable, and fundamentally static in its categories even if its parts were in motion.

Scientific materialism and the crisis it created 🔗

By the seventeenth and eighteenth centuries, what Whitehead would later call scientific materialism had become the dominant metaphysical framework of Western intellectual life. In Whitehead’s own description, this view presupposes “an irreducible brute matter, spread through space in a flux of configurations” – matter that is “senseless, valueless, purposeless,” simply following external laws imposed on it from outside its own nature.

The success of this framework was undeniable. Newtonian mechanics explained planetary motion, optics, and much of terrestrial physics with extraordinary precision. But its limitations were equally real. A universe of dead, inert matter operating through mechanical external relations had no obvious room for life, consciousness, value, purpose, or genuine novelty. These realities of human experience became philosophically homeless – either reduced to matter (materialism) or assigned to a separate, non-material realm (idealism). Neither solution was satisfying.

More critically, the advance of science itself began to undermine scientific materialism’s own assumptions. In the nineteenth century, thermodynamics introduced the concept of entropy and the irreversibility of time – not a feature of a purely static world. Darwin’s theory of evolution described life as a dynamic, open-ended process of transformation across generations. At the turn of the twentieth century, Einstein’s special and general theories of relativity shattered the Newtonian picture of absolute space and time. And quantum mechanics introduced irreducible indeterminacy at the subatomic level, suggesting that reality at its most fundamental was not made up of fixed particles but of events, probabilities, and fields. The mechanistic universe was cracking.

Whitehead’s response: the philosophy of organism 🔗

It was into this intellectual crisis that Alfred North Whitehead stepped. Trained as a mathematician and logician – best known early in his career for co-authoring the monumental Principia Mathematica with Bertrand Russell – Whitehead turned to metaphysics in the later decades of his career, initially through philosophy of nature and then through systematic cosmology. He arrived at Harvard University in 1924 and delivered his landmark Gifford Lectures at the University of Edinburgh in 1927-28, which he revised and published in 1929 as Process and Reality.

Whitehead’s central argument was that scientific materialism – for all its practical success – had committed what he called the “fallacy of misplaced concreteness.” It had taken abstractions (matter, substance, particles) and mistaken them for the most concrete realities, when in fact the most concrete things are events and processes. For Whitehead, concepts such as “quality,” “matter,” and “form” are useful abstractions, but they are not the world’s basic building blocks. What is ordinarily conceived of as a single enduring object is, philosophically, a continuum of overlapping events.

He also directly challenged the Cartesian separation of mind and matter. Rather than dividing reality into two substances, Whitehead proposed that all actual entities – from electrons to human beings – involve some degree of experience and internal relatedness. This was not mysticism but a metaphysical reframing: what an occasion of experience is depends on how it relates to others, not on some fixed internal essence it carries in isolation.

The concept of the “actual occasion” and creative becoming 🔗

The most distinctive feature of Whitehead’s system – and the clearest marker of its break from static metaphysics – is the concept of the actual occasion (also called an “actual entity”). Rather than substances, Whitehead proposed that the fundamental units of reality are momentary events of experience. Each actual occasion arises, integrates its past, achieves a unique synthesis, and then perishes – becoming data for subsequent occasions. This process of arising, synthesizing, and perishing is what Whitehead means by becoming.

As the Internet Encyclopedia of Philosophy puts it, process philosophy makes the metaphysical claim that the world at its most fundamental level is made up of momentary events of experience rather than enduring material substances. The many occasions of the past become unified into a new present event, which in turn adds itself to what is available for the future: creativity is the ultimate principle of existence, and each new occasion is genuinely novel.

This is precisely where process philosophy reconnects with and transforms the ancient Greek debate. Heraclitus was right that becoming is fundamental. But Whitehead’s system does not abandon order – it shows how stability, pattern, and continuity emerge from and within dynamic process, rather than standing behind or beneath it. Being is not prior to becoming; it is an achievement of becoming. The river is not interrupted by the fact that its water constantly changes – the flowing is the river.

Process philosophy as a critique of Western metaphysics 🔗

Understood historically, process philosophy is not simply a new theory about what things are made of. It is a systematic critique of an entire tradition. Britannica describes process philosophy as opposing the traditional Western philosophical stress on being, permanence, and uniformity, arguing that reality – including both the natural world and the human sphere – is essentially historical: it emerges from a past and advances into a novel future, and cannot be grasped by the static spatial concepts of older metaphysics.

By insisting that substance metaphysics distorts our understanding of causation, consciousness, evolution, and even physics, Whitehead was challenging not just philosophers but the implicit assumptions underlying modern science itself. His critique was not anti-scientific – quite the opposite. He wanted philosophy to catch up with what science was actually discovering: a relational, dynamic, process-structured universe. Process philosophy rejects the idea that entities can only influence each other through external relations, and replaces it with a conception of internal relatedness – where the past genuinely participates in and shapes the present.

The broader tradition: Bergson, Hegel, and Dewey 🔗

Whitehead did not work in isolation. Several major thinkers contributed to the broader tradition within which process philosophy took shape. Henri Bergson argued that scientific concepts falsify the lived experience of duration and change by imposing spatial frameworks on what is inherently temporal and fluid. Hegel had earlier described history as a dynamic, dialectical unfolding – a vision of reality as developmental process rather than fixed structure. William James and John Dewey, both of whose work Whitehead acknowledged in the preface to Process and Reality, developed process-oriented accounts of knowledge, experience, and inquiry in the American pragmatist tradition.

What distinguished Whitehead’s contribution was his ambition to construct a fully systematic and rigorous cosmological framework – one that could integrate the insights of modern science, the findings of human experience, and the deepest questions of metaphysics into a coherent whole. Process philosophy, in his hands, became an attempt to reconcile the diverse intuitions of religious, scientific, and aesthetic experience into a single, integrated scheme of thought.

Why the historical context matters 🔗

The Sitz im Leben of process philosophy – its historical setting – is essential to understanding what it is and why it matters. It did not emerge from purely abstract speculation. It arose from a specific moment of intellectual crisis: the collision between a dominant tradition of static substance metaphysics and a century of scientific discoveries that that tradition could not adequately explain. It arose from the residual power of an ancient debate between Heraclitus and Parmenides that had never been fully resolved. And it arose from a thinker who had moved from the precision of formal logic to the complexity of lived reality – and found that reality refused to stay still.

Process philosophy’s core claim is not that change is more important than stability, but that stability must be understood as an achievement within a fundamentally dynamic world. Becoming is not the enemy of being – it is its condition. And that shift in perspective, from a world of things to a world of processes, carries consequences for how we understand consciousness, time, causation, God, and the nature of scientific knowledge itself.

What do you think? If reality is fundamentally processual rather than substance-based, what does that mean for how we think about personal identity – are “you” the same person you were ten years ago, or a continuation of overlapping occasions of experience? And does giving philosophical primacy to becoming over being make the world feel more truthfully described, or does it challenge something we intuitively hold about the stability of reality?
