On Nature (Fragments)
The 120-or-so surviving fragments of Heraclitus of Ephesus — the philosophical sayings of "the Obscure," traditionally collected as one lost book called Peri Physeōs
Tradition: Pre-Socratic Greek philosophy
Logos, flux, unity-of-opposites — Heraclitus's gnomic philosophical fragments, the founding statement of process-philosophical thinking
Heraclitus of Ephesus (c. 540-480 BC) is one of the most important pre-Socratic philosophers, known through approximately 120 surviving fragments collected from later authors' quotations. The fragments, traditionally collected as a single lost work called On Nature (Peri Physeōs), develop several central philosophical themes: the doctrine of logos (the rational principle ordering the cosmos), the doctrine of flux (everything is in continuous change — "you cannot step into the same river twice"), the doctrine of unity-of-opposites (apparent opposites are unified at a deeper level), the doctrine of fire as the cosmological principle. Heraclitus's gnomic, paradoxical style earned him the epithet "the Obscure." His thought has shaped subsequent philosophy decisively: Plato (the Cratylus engages Heraclitus extensively), the Stoics (who developed the logos doctrine), Hegel (who reads dialectic into Heraclitus), Nietzsche, Heidegger, and process philosophy.

School Embodiments
Heraclitus is the founding figure of Western process-philosophical thinking — the doctrine of flux, the priority of becoming over being.
"All things flow — you cannot step into the same river twice." (Heraclitus, fragment via Plato)
Stoic logos doctrine develops from Heraclitus. The cosmic-rational order, the doctrine of fire as cosmological principle, are Stoic-Heraclitean.
"Logos as the cosmic-rational order, developed by the Stoics from Heraclitus." (Heraclitus, paraphrasing)
A retrospective relation: Hegel reads Heraclitean dialectic as proto-dialectical-idealist. Hegel famously said "there is no proposition of Heraclitus which I have not adopted in my Logic."
"Hegel's adoption of Heraclitean dialectic." (Heraclitus, paraphrasing the reception)
A complicated relation: Plato engages Heraclitus extensively (especially in the Cratylus and Theaetetus); Platonic forms partly developed against Heraclitean flux.
"Plato's engagement with Heraclitean flux." (Heraclitus, paraphrasing)
A cross-tradition affinity: Heraclitean unity-of-opposites and continuous transformation has substantial parallels with Daoist tradition.
"Cross-tradition unity-of-opposites and continuous transformation." (Heraclitus, paraphrasing)
Heraclitus's framework is broadly naturalist — natural-philosophical analysis without supernatural categories.
"Natural-philosophical analysis of cosmic order." (Heraclitus, paraphrasing)
A retrospective relation: Neoplatonic engagement with Heraclitus is mediated through the broader Greek-philosophical tradition.
"Neoplatonic engagement with Heraclitus." (Heraclitus, paraphrasing)
A retrospective relation: Marxist dialectical materialism reads Heraclitus as a proto-dialectical-materialist (Lenin's notebooks on Heraclitus are extensive).
"Marxist engagement with Heraclitean dialectic." (Heraclitus, paraphrasing)
A retrospective relation: the Heraclitean cosmic-logos has been read as a precursor to panpsychist frameworks.
"Heraclitean logos as panpsychist precursor." (Heraclitus, paraphrasing)
Internal Tensions
The fragmentary nature of the surviving texts has always made Heraclitean interpretation contested. Different reconstructions of the underlying philosophical framework — the "strict" flux reading (Plato, Aristotle), the Hegelian dialectical reading, the modern process-philosophical reading — yield substantially different Heraclituses. The lost original work makes definitive interpretation impossible.
I. Time
Time as the medium of continuous flux; the unity-of-opposites in temporal flow.
Attributes
II. Space
The cosmic space as the theatre of flux; emergent rather than substantival.
Attributes
III. Matter
Fire as the cosmological-energetic principle; matter as emergent from the elemental transformations.
Attributes
IV. Observer
The philosophical observer engaged with the logos — embodied, plural. Cosmic logos as ordering framework.
Attributes
V. Energy
The energetic principle of fire as the basic cosmological energy; the unity-of-opposites as the structural energy.
Attributes
VI. Information
The fragments themselves as preserved philosophical-aphoristic information; the logos as the cosmic-information principle.
