Heraclitus's major work, of which only 130 fragments survive, quoted by later authors. It set out his doctrine of the universal Logos, the primordial fire, and perpetual becoming.

A collection of maxims on the universal reason (Logos) that governs the cosmos. Heraclitus argues that the Logos is common to all people, yet most live as though they possessed a reason of their own.

Reflections on the unity of opposites (cold/hot, life/death, waking/sleeping) and on permanent change. These fragments are the source of the famous saying 'Everything flows' (Panta rhei).

Maxims on the city, law, and justice. Heraclitus argues that all human laws are nourished by a single divine law, and criticizes democracy in favor of rule by the best.

Although this Logos exists always, men are unable to understand it, both before hearing it and after they have heard it for the first time.

You cannot step into the same river twice, for new waters are always flowing.

War is the father of all things and the king of all things; some it has shown as gods, others as men; some it has made slaves, others free.

All things are exchanged for fire, and fire for all things, as goods are exchanged for gold and gold for goods.

He deposited his book in the temple of Artemis, and according to some, he deliberately wrote it in an obscure style so that only those of ability could access it, and to avoid being looked down upon by the common people.

Heraclitus's hometown, a prosperous Ionian city on the Aegean coast of Asia Minor. It was here that he was born, lived, and died, refusing to leave despite invitations from other cities.

One of the Seven Wonders of the Ancient World, located in Ephesus. Heraclitus deposited his work 'On Nature' there, choosing this sacred site to restrict access to initiates alone.

A major neighboring Ionian city and the birthplace of Greek philosophy, home to Thales, Anaximander, and Anaximenes. Heraclitus was familiar with their theories and set himself apart by making fire the primary principle of all things.

An Ionian island near Ephesus and the homeland of Pythagoras, whom Heraclitus sharply criticized for his vast learning without genuine wisdom. The two philosophers represent two opposing visions of knowledge.
