Fragments
Surviving fragments of Heraclitus of Ephesus (Diels–Kranz numbering)
Tradition: Pre-Socratic Greek philosophy
Reality is process, not substance: the world is fire, the river never the same, the logos the only stable thing
Heraclitus' fragments are the foundational text of process philosophy in the Western tradition. Roughly 120 fragments survive — most quoted by later writers like Plutarch, Clement, and Simplicius — from what was apparently a single book deposited in the temple of Artemis at Ephesus. The fragments are deliberately compressed and gnomic ("Nature loves to hide," DK 123), but their cumulative argument is recognisable: reality is in ceaseless transformation, opposites are dynamically united, fire is the underlying metaphor for what becomes, and the logos — the rational pattern of the cosmic flux — is the same in the universe and in the human mind. They are the closest the ancient Greek world comes to a relational-process metaphysics, and they have been read fruitfully by Hegel, Nietzsche, Heidegger, and Whitehead.

School Embodiments
Whitehead read Heraclitus as the first process philosopher and cited the river fragment as a touchstone. The doctrine that reality consists of becoming rather than enduring substance is unambiguously present in the fragments.
"Upon those who step into the same rivers, different and again different waters flow." (DK 12)
The "unity of opposites" passages treat properties as relations rather than intrinsic: the road up and the road down are one, sea is both pure and polluted, the bow is named life but does the work of death.
"The road up and the road down are one and the same." (DK 60)
The cosmic fire that "all things are an exchange for" approaches a monistic, immanent divine — the closest pre-Socratic anticipation of later pantheist metaphysics. Spinoza's deus sive natura inherits something of this register.
"All things are an exchange for fire, and fire for all things, just as goods for gold and gold for goods." (DK 90)
The Stoics took over the cosmic logos and the doctrine of fire as fundamental directly from Heraclitus, building both into the core of their physics. The fragments' moral and political aphorisms also prefigure Stoic cosmopolitan reason.
"Listening not to me but to the Logos, it is wise to agree that all things are one." (DK 50)
Internal Tensions
Heraclitus reads as a thoroughgoing relationalist on time, space, and matter, but he also speaks of fire as the underlying substance ("all things are an exchange for fire") in a way that flirts with substantival monism. The tension is productive: it is what lets the Stoics read him as the founder of a substantival cosmology of pneuma-fire, while Whitehead reads him as the founder of process. Both readings have textual support; the fragments do not resolve the tension.
I. Time
Time is the medium of universal flux but is itself relational — there is no Newtonian container, only the ordered succession of changes. The famous river fragment (DK 12 / DK 91) is the canonical statement. The "Great Year" fragments imply a cyclical cosmology (DK 30: "this world-order, the same for all, no god nor man made, but it always was and is and will be — an ever-living fire, kindling in measures and going out in measures") in which fire kindles and quenches in eternal cycles.
Attributes
II. Space
Space is not thematised directly but is presupposed as the field within which change unfolds. Heraclitus is not a Newtonian; the unity-of-opposites passages and the relational character of all properties (DK 60, DK 61: "sea is the purest and foulest water — for fish drinkable and life-giving, for men undrinkable and lethal") suggest a thoroughly relational space rather than an empty container.
Attributes
III. Matter
Matter is what changes: water, earth, and fire interconvert in measured exchanges (DK 31, DK 90). The conservation principle is explicit — the measures (metra) of fire kindling and quenching are preserved — but matter has no enduring substance. The closest Heraclitus comes to a fundamental "stuff" is fire, and fire is precisely the element whose nature is to be in continual transformation.
Attributes
IV. Observer
The observer is embodied, plural, and active, but most people are asleep — "the many are like sleepers, each turned away into a private world" (DK 89). The wise observer participates in the same logos that orders the cosmos. Knowledge is immediate (gained by attending to the world rightly) but most miss it: "though the Logos is common, most live as if they had a private understanding" (DK 2). The agency is active — the wise must rouse themselves — but the framework is cosmic, not personal-theistic.
Attributes
V. Energy
Fire is the most fundamental element and the closest pre-Socratic anticipation of an energy ontology — substantival, infinite, and conserved across its measured transformations. Energy is reversible at the cosmic scale (the eternal kindling/quenching cycle) while irreversible at the local scale of any particular thing.
Attributes
VI. Information
The logos is the closest Heraclitan concept to "information" — the rational pattern that holds across the universal flux, the same in the cosmos and in human reason. It is relational (intelligible only as the pattern of relations among changing things), conserved at the cosmic scale, and continuous. Personal information is *not* conserved — the wakeful self dies, dies again into the river, and there is no persistence of the empirical individual ("for souls it is death to become water, for water death to become earth," DK 36).
