Heraclitus
Everything flows. The world is fire, and stillness is a lie we tell ourselves.
Heraclitus wrote in riddles and refused to explain them. He believed the universe is a process, not a thing, an eternal fire that kindles and goes out in measure. Opposites need each other. Day defines night. War fathers peace. The logos holds it all together, but most people walk through life asleep to it. He was difficult, solitary, and possibly the most original thinker before Socrates.

Works
Fragments
fragmentaryAround 130 fragments survive of a single work, probably called On Nature. Written in deliberately obscure, aphoristic prose. The fragments concern the logos, the unity of opposites, and the image of the cosmos as an ever-living fire.
On the Soul
fragmentaryHeraclitus saw the soul as made of fire, the noblest element. A dry, fiery soul is wise; a wet soul is foolish or drunk. These fragments, distinct from his cosmic writings, concern self-knowledge and the depth of inner life.
Life & Moments
Born in Ephesus
Born into an aristocratic family in Ephesus, a wealthy Ionian city dominated by the great temple of Artemis.
Born in Ephesus
Heraclitus is born in Ephesus around 535 BCE, into one of the city's aristocratic families. He inherits a ceremonial kingship, a priestly title more than a political one, and gives it away. The city is prosperous, crowded, politically fractious. He watches it with contempt and writes as if he has no patience for anyone.
Declines the Kingship
Heraclitus holds a hereditary priestly kingship and hands it to his brother. The gesture is not humility: he has made clear what he thinks of his fellow citizens, calling them fools who mistake custom for understanding. He steps back from public life not to escape it but because he finds it beneath the questions that occupy him.
Fire and Flux
Heraclitus taught that the cosmos is an ever-living fire, measured in its kindling and going out. Stability is illusion; process is real.
Depositing His Book
Heraclitus reportedly deposited his book in the Temple of Artemis at Ephesus, deliberately making it hard to access. He wrote in riddles and despised the masses. Only fragments survive, but they are among the most quoted words in philosophy.
Composes On Nature
Around 500 BCE Heraclitus deposits a prose work, later called On Nature, in the temple of Artemis at Ephesus. He writes in riddles on purpose, to keep the foolish from misreading him. The fragments that survive are short, sharp, and hard to pin down: fire is the source of all things, opposites are the same, you cannot step into the same river twice. Each sentence opens into several meanings at once.
Withdrawal from Public Life
Heraclitus refused political office and reportedly wandered the mountains, living on coarse food and contempt for the crowd.
Withdraws to the Mountains
The accounts say Heraclitus left Ephesus altogether and lived for a time in the hills, eating plants and whatever the land offered. Some read this as madness, others as deliberate solitude. His contempt for the city had always been total. Going to the mountains may have been the only honest thing left to do.
Death in Ephesus
He died in Ephesus, possibly from dropsy. One story says he buried himself in dung seeking a cure and suffocated. The manner matters less than the riddles he left behind.
Dies in Ephesus
Heraclitus dies around 475 BCE, reportedly from a severe illness. The stories about his death are probably inventions: that he buried himself in manure hoping the warmth would cure him, that he asked physicians to riddle their way to a diagnosis. The death stories suit the legend of the difficult, impossible man. What is certain is that almost nothing he wrote survives whole.

- Zeno of Citium
The Stoics adopted Heraclitus’ concept of the logos and his image of the cosmos as a living fire. They considered him a forerunner of their physics.
