Empedocles

Life and Legend

Empedocles was born around 494 BCE in Acragas (modern Agrigento, Sicily), one of the wealthiest and most culturally vibrant Greek cities. He came from a prominent aristocratic family — his grandfather reportedly won the horse race at Olympia. Ancient sources portray him as a flamboyant, charismatic figure who dressed in purple robes, wore a golden crown, and bronze sandals, and who claimed divine status. Diogenes Laërtius records stories of his miraculous deeds: healing plagues by diverting rivers, calming winds, and even resurrecting a woman from apparent death.

Politically, Empedocles was a democratic leader who reportedly refused the kingship of Acragas and helped overthrow an oligarchic faction. He was eventually exiled and spent his later years in the Peloponnese. The most famous legend about his death — that he leaped into the crater of Mount Etna to prove his divinity, or to conceal his death and appear to have been assumed into heaven — is probably apocryphal but captures the mythic aura that surrounded him.

The Four Roots

Empedocles' philosophical system was designed to preserve the Parmenidean principle that nothing comes from nothing while explaining the evident reality of change and plurality. His solution was to posit four eternal, qualitatively distinct elements — which he called 'roots' (rhizōmata) and associated with divinities: Zeus (fire), Hera (air), Nestis (water), and Aidoneus (earth). These roots are uncreated, imperishable, and unchangeable, satisfying Parmenidean requirements. What we perceive as coming-to-be and passing-away is in fact the mixing and separating of these eternal elements.

Love and Strife

The agents of mixture and separation are two cosmic forces: Love (Philia) and Strife (Neikos). Love is a force of attraction that brings the unlike roots together into mixtures, creating composite things. Strife is a force of repulsion that separates and divides. The history of the cosmos is a grand cycle governed by the alternation of these forces:

1. Under the complete dominance of Love, all four roots are perfectly mixed into a homogeneous sphere (the Sphairos) — a state of undifferentiated unity.
2. Strife gradually enters and begins separating the elements, creating a differentiated cosmos of distinct things.
3. Strife dominates completely, separating all elements into four distinct masses.
4. Love re-enters and begins mixing them again, returning toward the Sphairos.

Our world exists at some intermediate stage of this cycle, with both Love and Strife active simultaneously.

Biology and Proto-Natural Selection

Empedocles proposed a remarkable account of the origin of living things during the phase when Love is recombining previously separated elements. In the early stages, random combinations produce all manner of creatures — heads without necks, arms without shoulders, eyes without faces. Most of these monstrous combinations are not viable and perish. Only those that happen to be well-adapted — whose parts fit together functionally — survive and reproduce. This account, sometimes called 'proto-natural selection,' anticipates Darwin's principle of survival of the fittest, though Empedocles did not propose a mechanism of hereditary variation.

Theory of Perception

Empedocles developed a sophisticated theory of sense perception based on the principle that 'like is known by like.' Each element in us perceives the corresponding element in external things through physical effluences (aporrhoai) — tiny streams of particles that flow from objects and enter pores (poroi) in the sense organs. Vision occurs when fire-effluences from objects meet the internal fire of the eye. This pore-and-effluence model was the first systematic attempt at a mechanistic theory of perception.

Poetry and Religion

Empedocles composed two major poems in hexameter verse: 'On Nature' (Peri Physeōs), containing his physical theory, and 'Purifications' (Katharmoi), a religious poem on the transmigration of souls. In the Katharmoi, Empedocles declares himself a fallen god, exiled from the divine sphere for the sin of bloodshed (perhaps a metaphor for the primordial encroachment of Strife), doomed to wander through mortal incarnations until purified. This Orphic-Pythagorean religious dimension coexists uneasily — or perhaps deliberately — with his mechanistic physics.

Legacy

Empedocles died around 434 BCE. His four-element theory was adopted by Aristotle and became the standard physical theory of Western science and medicine until the chemical revolution of the 18th century. The Hippocratic theory of four humors, Galen's medical system, and medieval alchemy all rest on Empedoclean foundations. His cosmic cycle of Love and Strife influenced Stoic cosmology and modern cyclical theories of history. Darwin himself acknowledged the anticipation of natural selection in Empedocles. In 1999, the discovery of the Strasbourg Papyrus added significant new fragments of his poetry to the corpus.
