One logos governs all: the divine is the unity of the world's opposites

Heraclitus' logos; "all things are one"; "God is day and night, winter and summer"

Heraclitus of Ephesus c. 540 BC · c. 480 BCEverything changes without rest, yet the world holds together by a common measure: unity comes from the tension of opposites.

What it claims

The divine is not a separate being who made the world: it is the single order of the world itself, its logos, which shows itself in all its opposites.

Why

One wisdom governs all things, no one made the world, and the god is day and night, winter and summer: the divine is the world itself.

The same idea through history
Heraclitus of Ephesus500 BCHeraclitus wrote a book of which only fragments remain. The divine in it is a single wisdom, the logos, present in all things, which may or may not be called Zeus, and which takes the form of all the world's opposites.
Benedictus de Spinoza1677Spinoza says that God and Nature are one, by a geometrical demonstration. The comparison is useful but should not be pushed: Spinoza proves a single substance, Heraclitus demonstrates nothing of the kind and speaks of a wisdom that orders the world.
In short

"One logos governs all: the divine is the unity of the world's opposites" is an argument by Heraclitus of Ephesus (Fragments B1, B30, B32, B41, B50, B67 (c. 500 BC), 500 BC) on the question "Does God exist?" (answer: pantheism). Its claim: The divine is not a separate being who made the world: it is the single order of the world itself, its logos, which shows itself in all its opposites. According to AskPhilosophy's logic check (Z3 solver), the argument is valid only if one grants a premise the author leaves unstated (P5). AskPhilosophy presents 3 objections, 1 of them with a documented reply, and the original text behind each premise, checked word for word.

Fragments B1, B30, B32, B41, B50, B67 (c. 500 BC)
Valid with an implicit premise

The Greek poets told of gods who made the world. Heraclitus of Ephesus, around 500 BC, says otherwise. The world, he writes, no god or man has made: it has always been a living fire, kindled and quenched in measure. This world is governed by a logos, a common reason or word, and all things are one. As for "God", he is not someone apart: "God is day and night, winter and summer, war and peace, surfeit and hunger." The divine would then be the unity of the world's opposites, the single wisdom that runs through it. The word "pantheism" is much later, and the meaning of the lost book is debated: we know it only through fragments quoted by other authors, in translation (Burnet 1920, Weil 1953).

P1All things come to pass according to one and the same logos, common to all, which most people fail to grasp; wisdom is to acknowledge that all things are one.
P2This wisdom is single: it is the thought that steers all things through all things, and it is unwilling and willing to be called by the name of Zeus.
P3The god is not separate from the world's opposites: he is day and night, winter and summer, war and peace, surfeit and hunger, and takes various shapes, like fire named according to the scent mingled with it.
P4This world, the same for all, no god or man has made: it was ever, is now and ever shall be an ever-living fire, kindling and going out in measure.
P5 · implicit premiseIf the single wisdom that governs the world is the god, if this god is identical with the world's opposites, and if no one made the world, then no god exists apart from the world.
Therefore the divine is not a separate being who made the world: it is the single order of the world itself, its logos, which shows itself in all its opposites.

click a premise to reject it

If you accept every premise, logic forces you to accept the conclusion. So the debate is about the premises.
Checked by a logic solver: the premises cannot all be true while the conclusion is false.
Without the implicit premise: Without P5, one can accept P1 to P4 and imagine a wisdom that governs the world from outside: it would be present everywhere through its action without being the world, and the world would have had no creator because it is eternal. That is what those who read B108 as a "separate" wisdom suggest.
The argument is valid with the hidden premise P5. P1 and P2 say that the same wisdom runs through all things; P3 identifies the god with the set of opposites; P4 rules out a creator. P5 concludes that the divine is nowhere but in the world. The attacks target P3 (can one say the god is everything and its opposite? see Aristotle) and P5 (fragment B108 speaks of a wisdom "apart from all", which can be read as transcendence).
Analogy. Think of a melody. Its notes differ, high and low, long and short; without these differences there would be no melody. Yet we do not say the melody is something else existing apart from the notes: it is their agreement. For Heraclitus the divine is both what sets the world's opposites against each other and what holds them in accord.

Aristotle 350 BC · attacks premise 3

In the Metaphysics, Aristotle lays down that the most certain principle is that the same attribute cannot at the same time belong and not belong to the same subject in the same respect. He adds that it is impossible to believe the same thing to be and not to be, as some think Heraclitus says. If the god were day and night, war and peace, the same being, he would have contrary attributes at once. Aristotle himself doubts that Heraclitus really thought so: one may say a thing without believing it.

Ephesus replies
H
Heraclitus 500 BC · Heraclitus (earlier text)
A fragment answers this kind of reproach in advance: people do not know how what is at variance agrees with itself, for it is an attunement of opposite tensions, like that of the bow and the lyre.
The debate goes on (our summary) Our summary: fragment B51 predates Aristotle and does not answer his principle by name. It can be read as saying that the unity of opposites is a tension and not the identity of A and not-A, but this reading is not certain. The doubt remains: does a god who is "everything" say anything precise?
Where the debate stands (our summary)Our summary: a deep, open disagreement. One reading makes Heraclitus deny non-contradiction; another sees opposites united by a measure or tension, without contradiction. Aristotle himself hesitates over what to attribute to him.
Thomas Aquinas 1268 · attacks the conclusion

In the Summa Theologiae Thomas rejects the idea that God is the world-soul or a principle that enters into the composition of things. God is the first efficient cause. But an efficient cause is not the matter of what it produces, and what is part of a compound does not act first: the hand does not act, but the man by his hand. So God cannot be a part of the world.

no reply
No reply possible: objection raised in 1268, after the author's death (-480).
The debate goes on (our summary) Our summary: Thomas is not aiming at Heraclitus, dead for nearly two thousand years, but at theses he judges close. A defender of the logos would answer that the argument assumes a God who causes the world, whereas fragment B30 precisely refuses that a god or man made the world: the objection starts from a premise (a produced world) that the opponent rejects.
Where the debate stands (our summary)Our summary: a disagreement at the starting point rather than in the logic. For Thomas a world that exists through another requires a first cause; for the pantheist the world is eternal and self-sufficient. The debate between these two starting points remains open.

Heraclitus himself (fragment B108) 500 BC · attacks premise 5

Another fragment points the other way from the pantheist reading: "of all whose discourses I have heard, there is not one who attains to understanding that wisdom is apart from all". If wisdom is "apart from all", one can infer that the divine goes beyond the world, and that P5 is concluded too fast.

no reply
We have not yet found a direct reply by Ephesus in the texts.
The debate goes on (our summary) Our summary: the sense of "apart from all" is debated. It may mean that wisdom is other than what people call wise (the poets, the learned), not that it leaves the world; but the fragment does not decide. The difficulty also comes from translation, which differs between Burnet and Weil.
Where the debate stands (our summary)Our summary: an open point. Readings diverge between an immanent divine (the logos is in the world) and a divine apart; the lost book does not give enough context to decide.
