Empedocles: The Four Elements and Forces of Love and Strife

Around 450 BCE, a philosopher-poet from Acragas in Sicily put forward one of the most ambitious theories in the history of Western thought. Empedocles wanted to answer a question that had troubled Greek thinkers for generations: how can the world constantly change if, as Parmenides argued, nothing can truly come into being or pass away? His answer was elegant and radical – the world is made of four eternal elements, and everything we see is the result of two opposing cosmic forces endlessly mixing and separating them. This framework, built on the “four roots” and the forces of Love and Strife, became one of the most influential cosmological systems in antiquity.

The philosophical problem Empedocles was solving 🔗

To understand why Empedocles’ theory mattered, you need to understand the problem he inherited. Parmenides of Elea had argued that reality is single, unchanging, and indivisible – a position known as Eleatic monism. If nothing can come from nothing, and nothing can be destroyed into nothing, then genuine change is impossible. The world of multiplicity and motion you perceive through your senses must be an illusion.

This was philosophically powerful but practically absurd. Trees grow, seasons change, living things are born and die. How do you account for that while accepting Parmenides’ core logical insight? Empedocles’ response was to appropriate Parmenides’ own principles and turn them against his conclusion. He agreed that nothing can come from nothing – but he transferred the changelessness Parmenides attributed to the whole of reality down to the level of basic constituents. The fundamental building blocks of nature are eternal and unchanging. But those blocks can combine and separate, and that process is what we experience as change. In doing so, he replaced the static singularity of Parmenides’ world with a dynamic plurality.

The four roots: earth, air, fire, and water 🔗

Aristotle credits Empedocles with being the first to distinguish clearly these four elements as the material basis of everything that exists. Empedocles called them rhizomata – “roots” – rather than elements, a term that captures their foundational role. Everything in the universe, from rocks to blood to the human body, is a compound of these four in varying proportions.

Crucially, the roots themselves do not change. Nothing either comes into being or is destroyed; things are merely transformed depending on the ratio of basic substances to one another. This is a decisive move: it preserves the Parmenidean demand for permanent, uncreated being while still making room for the changing world we actually inhabit.

Empedocles identified each root with a deity – Zeus for fire, Hera for air, Aidoneus for earth, and Nestis for water. This was not mere poetic decoration. The names of deities indicate that each root has an active nature and is not just inert matter. The roots have qualities, tendencies, and affinities. Fire and air are compatible; fire and water are naturally antagonistic. These inherent qualities matter for what kinds of mixtures are possible.

Proportional mixture and specific substances 🔗

One of the most original aspects of Empedocles’ theory is the idea that different substances result from different proportions of the roots. This is not vague – Empedocles says that flesh and blood are composed of approximately equal parts of earth, fire, water, and air, while a different proportion of elements produces bone. Every distinct substance in the world reflects a specific elemental recipe. The richness and variety of nature is explained not by the roots themselves differing, but by the ratios in which they combine. This is a genuinely reductionist move that anticipates later scientific thinking about matter.

Love and Strife: the two cosmic forces 🔗

The four roots alone cannot explain motion or change. Something has to drive their combination and separation. This is where Empedocles introduces the two forces that make his system dynamic: Love (Philia or Philotes) and Strife (Neikos). These he personifies as Love – a force of attraction and combination – and Strife – a force of repulsion and separation. Importantly, these were not metaphors. Empedocles believed they were real physical and material forces operating in the cosmos.

Love works by bringing together roots of different types into harmonious blends. Strife drives them apart, causing elements to withdraw into their own kind. The real world we inhabit is at a stage in which neither force fully dominates – we exist in a state of ongoing tension and partial mixture, which is exactly why our world looks the way it does: neither a perfect unity nor a complete chaos, but something in between.

Love as a creative force 🔗

When Love is dominant, the four roots are drawn together into ever-greater unity. At its extreme, Love produces what Empedocles calls the Sphere – a perfect, divine, motionless unity in which all the elements are blended completely and uniformly. The Sphere is a total mixture under the influence of Love, and it is reminiscent of Parmenides’ own description of Being – spherical, uniform, and at rest. Empedocles seems to have been deliberately echoing his predecessor, suggesting that the Parmenidean One is a real state of the cosmos – but only one phase in an ongoing cycle.

Strife as a separating force 🔗

Strife breaks into the Sphere and begins pulling the roots apart. As it gains dominance, the elements separate into distinct masses: earth at the centre, water surrounding it, air forming the next layer, and fire at the periphery. This geocentric formation is what the ancients usually recognised as our cosmos. It is Strife that generates the differentiated, structured world of distinct things. The living world we inhabit – with its variety, conflict, and particularity – is the product of Strife’s separating influence, though Love is never entirely absent from the picture.

This leads to a striking conclusion: the world as we perceive it is the joint product of Love and Strife. Strife is not simply destructive any more than Love is simply generative. Both forces are necessary for the world as we know it to exist at all.

The cosmic cycle 🔗

For Empedocles, the universe runs through an endless cycle governed by the alternating dominance of Love and Strife. One force does not finally triumph over the other; rather, their periods of dominance succeed one another in continual alternation. The cycle begins with total unity under Love (the Sphere), Strife then intrudes and drives separation until the elements are fully divided, then Love reasserts itself and brings them back together, and so on without end.

In each phase of this cycle, as the elements mix or separate, a cosmos comes into being and living creatures emerge. The cosmos exists in a state of constant flux, beneath which there is a certain stability in the eternity of the elements themselves. Change is real, but it rests on a foundation of permanent things. This is Empedocles’ resolution to the tension between Parmenides and the observable world: permanence is real, but it operates at the level of the roots, not the level of the things we see.

The origin of living things 🔗

Empedocles’ account of how living creatures arise is one of the most vivid passages in early Greek philosophy. In the early phases of a cosmic cycle, as Love begins drawing elements together, there appeared strange results – heads without necks, arms without shoulders, and eventually hybrid creatures like ox-headed human-bodied forms. These were the products of random elemental combination. Over time, only creatures with compatible, functional arrangements survived. Unlike Darwin’s theory, there is no gradual evolution of one species into another; all the variety of nature is produced in a great burst at the beginning, and whittled down by extinctions into the creatures we see today. Scholars have noted a structural resemblance to natural selection here, though the mechanism is very different.

Bridging Parmenides and Heraclitus 🔗

One reason Empedocles holds such an important place in the history of philosophy is that he attempted to reconcile two apparently contradictory positions. Parmenides insisted that reality is one and unchanging. Heraclitus insisted that everything is in constant flux. By positing elements bound together by Love and separated by Strife, while the elements themselves remain changeless, Empedocles was able to reconcile Parmenides with Heraclitus. Change is real, but it operates on top of a permanent substrate.

His work also influenced the development of atomic theory by Leucippus and Democritus, who took the logic of permanent, unchanging basic units and pushed it further – replacing four qualitatively distinct roots with quantitatively differing atoms. The conceptual architecture Empedocles built – eternal constituents, external forces driving combination and separation, change as rearrangement rather than creation – became the template for much of later ancient cosmology.

Empedocles’ lasting significance 🔗

In the middle of the fifth century BCE, Empedocles of Acragas formulated a philosophical program that influenced later philosophy, medicine, mysticism, cosmology, and religion. The four-element theory became the standard framework for understanding matter in the ancient and medieval worlds, adopted and adapted by Aristotle, carried into medieval Islamic and European thought, and still present in Renaissance medicine and alchemy. The idea that all matter is composed of a small number of fundamental types – distinguished by their qualities and capable of combining in infinite ratios – is not far removed in spirit from modern chemistry, even if the details are entirely different.

More philosophically, Empedocles showed that it was possible to take Parmenidean logic seriously without abandoning the world of experience. The four-element theory was put forward to rescue the phenomenal world from the static monism of Parmenides. That rescue operation – preserving both permanence and change by locating them at different levels of reality – set the agenda for the pluralists and atomists who followed.

What do you think? If the elements are truly eternal and unchanging, does that mean the universe as a whole has no real beginning or end – only an endless reshuffling of the same fundamental material? And is Empedocles right that both unity and division are necessary for a world like ours to exist, or could a cosmos governed entirely by Love – or entirely by Strife – be a coherent possibility?
