Heraclitus (by Bramante)In existographies, Heraclitus (c.535-450BC) (IQ:185|#81) (Cattell 1000:721) (Stokes 100:4) (GPhE:#) (GPE:83) (ACR:9) [CR:121] was a Greek physical-based philosopher and thinker, aka “flux and fire philosopher”, the “riddler” as the stoics called him, or "the murky" (Copley, 1977) for his cryptic remarks, who can be contrasted with Parmenides (510-450BC), a mind-based (Ѻ) philosopher, his main rival, noted for his now lost On Nature (c.500BC), on the universe, politics, and theology, wherein he outlines a three element theory, according to which the universe is comprised of three principle elements: fire, earth, and water, but that fire was the primary element, controlling and modifying the other two, and that everything is in a continuous state of flux, or change, and war and strife between opposites is the eternal condition of the universe. To Heraclitus, there exists a universal tension, which ensures that change is continual, that everything is in a state of flux, whereby permanence does not exist in the universe, only the permanent condition of change as a result of the transformations of fire. [1]

Fragments
The surviving work of Heraclitus amounts to about 129 fragments; which are not written in continuous prose or verse, as other philosophers did, but in a series of short and penetrating observations; supposedly, something akin to the way Ludwig Wittgenstein writes (Ѻ); the following is a work in progress analysis of the key fragments, in chronological order:

“They vainly purify themselves by defiling themselves with blood, just as if one who had stepped into the mud were to wash his feet in mud. Any man who marked him doing thus, would deem him mad. And they pray to these images, as if one were to talk with a man's house, knowing not what gods or heroes are.”
— Heraclitus (c.495BC), Fragment 5 (Ѻ) (translator: John Brunet)

Fire | Living fire
The following are some of Heraclitus' fragmented statements on fire and or living fire:

“All things are an exchange for fire, and fire for all things … the transformations of fire are, first of all, sea; and half of the sea is earth, half whirlwind.”
— Heraclitus (c.470BC) [1]

“This world order, the same for all beings, was created neither by gods nor by humans; rather, it was always and is and will be eternal living fire kindled in measures and quenched in measure.”
— Heraclitus (c.470BC), Fragment 30 (Ѻ) (translator: Hans Diels) [1]

In 1967, Eugen Fink, in discussion with Martin Heidegger, comments on this:

“At first we interpret only the second half of the fragment. Lightning, we could say, is the sudden fire, the sun is the fire in orderly passage of the course of time, but πυρ αειςωον [eternal living fire] is something we do not find in the phenomenon like the lightning and the sun.”

(add)

God | Fire
Heraclitus stated the following view about god:

God is day and night, winter and summer; war and peace, satiety and hunger; he takes various shapes just as fire does.”
— Heraclitus (c. 470BC) [7]

“This [god as fire] is both willing and unwilling to be called by the name Zeus.”
— Heraclitus (c. 470BC) [7]

Egyptian | Greek philosophy
Heraclitus, supposedly, traveled to Egypt and studied their philosophy, in the manner of the "Thales study abroad tradition", but citation of this is difficult to find.

Egyptian history scholar Karl Lucker (1991), e.g., argues that while it has largely been assumed that Heraclitus was a was a haughtily independent scholar, that his thinking stems from a direction of Egyptian ontological heritage. [5]

Heraclitus’ fire, earth, water conceptualized three element theory, wherein fire is the primary element, in short, is strikingly familiar, in thematic form, to Heliopolis creation myth theory, according to which, fire (the sun) was self-engendered out of a primeval state universe of water (a flood) and earth (an land mound arisen).

Soul | Materialism
For humans, Heraclitus was of the view that the “soul is a spark of the substance of the stars and that the soul is immortal and returns upon death to the all-soul to which it is related.” [2]
-
“The death of ‘earth’ is to become water, the death of ‘water’ is to become air, and the death of ‘air’ is to become fire, and reversely.”
— Heraclitus (c.470BC), “noted saying”; cited by Marcus Aurelius (§4.46) in Meditations (167AD)
-
He was of the view that cosmic fire has its counterpart in the human soul, which in weak men is tainted by the ‘watery’ elements of sleep, stupidity and vice; conversely, the virtuous soul can survive the death of its physical body and eventually rejoin the cosmic fire. [1]

Ergon | Energy
The etymology of the term “energy”, according to American science writer Gerrit Feekes, is attributed to Heraclitus, who used the term "ergon" and or "en-ergon", meaning "the source of activity". Specifically, in his book about nature, he wrote: [3]

"En-ergon is the father of everything, king of all things and, out of it, all forms of contrast originate. Since ‘en-ergon’ is common to everything, it is vital for life itself.”

Others, however, state that Aristotle was the first to employ the term energy.

Change
The following is Heraclitus' view on change:

“Nothing endures but change, change is the only constant.”
— Heraclitus (c.470BC) [4]

In Heraclitus’ philosophy, see a trace of the principle of thermodynamic irreversibility, particularly in his river stepping dictum.

Stoics
The stoics (see: stoicism), the main immediate followers of Heraclitus, supposedly, found the fragments of his work so obscure that they nicknamed him the "riddler". [1]

Image | Note
The photo shown is from Renaissance artist Donato Bramante’s 1477 “Heraclitus and Democritus” painting (Ѻ), wherein Heraclitus is shown weeping, and Democritus laughing, characteristics attributed to them.

Quotes | On
The following are quotes on Heraclitus:

Man has been included among the most unexpected and most thrillingly lucky rolls of the dice in the game played by Heraclitus’ ‘great child’, whether he’s called Zeus or chance.”
Friedrich Nietzsche (1887), On the Genealogy of Morals (Ѻ)

“The world that Nietzsche shows us in his mirror is Heraclitean, a product of subtracting being and the subject from our concept of nature.”
— Peter Levine (1995), Nietzsche and the Modern Crisis of the Humanities (pgs. 144-45)

Heraclitus, who is ‘reluctant to make his utterances comprehensible’ (Cicero, 45B), is said to have written a book On Nature (c.500BC), in three parts, on the universe, politics, and theology. It is written ‘rather obscurely’ allegedly to prevent its being scorned by the common herd (Diogenes Laertius, 9.5).”
Patrick Walsh (1997), notes to Cicero’s On the Nature of the Gods [9]

“So this behind-the-scenes ‘fire’ is the first answer to a question first posed by Heraclitus and still very much alive: ‘what is it about our sensed world that makes it subject to measure and so much mathematics? What, for example, is behind the relation of the temperature we read off our thermometers to the warmth we feel, or the IQ kept in our files to the thoughts we are able to think?’”
— Eva Brann (2011), The Logos of Heraclitus (pgs. 63-64)
Logos of Heraclitus
Heraclitus, the flux and fire philosopher, was the first philosopher to give "logos" (Ѻ) serious attention.

Quotes | By
The following are noted quotes by Heraclitus:

“The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you choose, what you think, and what you do is who you become. Your integrity is your destiny ... it is the light that guides your way.”
— Heraclitus (c.500BC), On Nature (Ѻ)

“Man is most nearly himself when he achieves the seriousness of a child at play.”
— Heraclitus (c.490BC) (Ѻ)

“There is nothing permanent except change.”
— Heraclitus (c.470BC)
