Heraclitus of Ephesus
Everything flows — fire as the cosmic principle, the unity of opposites, the river that is never twice the same
Heraclitus left a single book, now lost; we have it only through some hundred and twenty fragments preserved as quotations in later authors. The book's title is traditionally given as "On Nature" (Peri Physeōs), the conventional title of pre-Socratic treatises, though Heraclitus may not have given it any title at all. The philosophical content visible across the fragments is striking and unmistakable: reality as the continual transformation of one underlying stuff (fire), the logos as the rational order beneath the flux, the unity of opposites, the priority of becoming over being. Plato and Aristotle both read him as their philosophical antipode; the Stoics adopted his cosmology as their own.

Heraclitus is the proximate source of the Western process tradition. Whitehead named him explicitly as the pre-Socratic ancestor of his own thought; Bergson's durée and the entire twentieth-century process philosophy trace back to the Heraclitean priority of becoming over being.
"All things flow; nothing abides." (Fragment via Plato, Cratylus 402a; "panta rhei")
The unity of opposites — the doctrine that contraries are constituted by their relation to one another — is a recognisably relational metaphysics. There is no day without night, no hot without cold, no up without down.
"The way up and the way down are one and the same." (Fragment B60)
A robust realism about the logos — the rational order present in things, discoverable but not invented. Heraclitus is no Sophist: the truth is real and one, even if most people sleep through their lives without seeing it.
"Listening not to me but to the Logos it is wise to agree that all things are one." (Fragment B50)
The Stoics adopted his cosmology wholesale — fire as the primary element, the logos as the rational principle of the cosmos, the eternal recurrence through cyclical conflagration (ekpyrosis). The Stoic-Heraclitean lineage is one of the cleanest in the ancient world.
"The cosmos, the same for all, none of the gods nor of humans has made, but it always was and is and will be: an ever-living fire, kindling in measures and going out in measures." (Fragment B30)
Internal Tensions
Plato's Cratylus reading of Heraclitus — that he denied any stable being whatsoever — is exaggerated. The logos is permanent precisely because change is regular; the unity of opposites holds because the contraries are co-constitutive. But Heraclitus did not systematise these doctrines; the fragments are aphoristic and elliptical, and the history of Heraclitus interpretation is the history of reading him as either a paradox-mongerer or as a profound systematic thinker — and there is real evidence on both sides.
I. Time
Relational — time is constituted by change; without flux it would not exist. Cyclical at the cosmic scale (the ekpyrotic conflagration), linear within a given transformation. Deterministic because the logos is rational and the cosmic process is ordered. "You cannot step into the same river twice, for other waters are continually flowing on." (Fragment B12)
Attributes
II. Space
Relational, flat, three-dimensional, locally causal. Space is the medium of the continuous transformation of fire into water into earth and back.
Attributes
III. Matter
Relational — fire, water, earth are not distinct substances but phases of one underlying transformation. Conserved through the exchange ("fire dies and air is born; air dies and water is born").
Attributes
IV. Observer
A single embodied person whose proper task is to wake up to the logos. Active agency through reason. Cosmic-ordering metaphysical agency: the logos itself, present in things, not a personal deity acting from outside.
Attributes
V. Energy
Fire is both the primary stuff and the cosmic energy. Substantival, conserved, reversible across the great cycle.
Attributes
VI. Information
The logos is the rational structure of the cosmos, persistent through all flux. Personal information: non-conserved — the soul, like fire, is part of the cosmic exchange.
