Héraclite d'Éphèse (en grec ancien Ἡράκλειτος ὁ Ἐφέσιος / Hêrákleitos ho Ephésios) est un philosophe grec de la fin du VIe siècle av. J.-C.
Héraclite
Heraclitus of Ephesus (Ancient Greek: Ἡράκλειτος ὁ Ἐφέσιος — Hērákleitos ho Ephésios, English Heraclitus the Ephesian) (ca. 535–475 BC) was a pre-Socratic Ionian philosopher, a native of Ephesus on the coast of Asia Minor.
Heraclitus is known for his doctrine of change being central to the universe, and that the Logos is the fundamental order of all.
Arkhè (ἀρχή) est un concept en philosophie de la Grèce antique, signifiant l'origine, le fondement, le commencement du monde ou le premier principe de toutes les choses. Le principe est ce qui commence mais également ce qui commande. Anaximandre, (610-547 av. J.-C.), passe pour être le premier à avoir utilisé ce terme pour désigner le principe des choses.
Arche (ἀρχή) is the beginning or the first principle of the world. The idea of an arche was first philosophized by Thales of Miletus, who claimed that the first principle of all things is water. His theory was supported by the observation of moisture throughout the world and coincided with his theory that the earth floated on water.
Thales' theory was refuted by his successor and estimated pupil, Anaximander. Anaximander noted that water could not be the arche because it could not give rise to its opposite, fire. Anaximander claimed that none of the elements (earth, fire, air, water) could be arche for the same reason. Instead, he proposed the existence of the apeiron, an indefinite substance from which all things are born and to which all things will return.
Anaximenes, Anaximander's pupil, advanced yet another theory. He returns to the elemental theory, but this time posits air, rather than water, as the arche. Anaximenes suggests that all is made from air through either rarefication or condensation (thinning or thickening). Rarefied, air becomes fire; condensed, it becomes first wind, then cloud, water, earth, and stone in order. The Arche is technically what underlies all of reality/appearances.
