“Hesiod’s good Eris transformed into the cosmic principle; it is the contest-idea of the Greek individual and the Greek state, taken from the gymnasium and the palaestra, from the artist’s agora, from the contest between political parties and between cities – all transformed into universal application so that now the wheels of the cosmos turn on it. Just as the Greek individual fought as though he alone were right and an infinitely sure measure of judicial opinion were determining the trend of victory at any given moment, so the qualities wrestle with one another, in accordance with inviolable laws and standards that are immanent in the struggle. The things in whose definiteness and endurance narrow human minds, like animal minds, believe have no real existence. They are but the flash and spark of drawn swords, the quick radiance of victory in the struggle of the opposites.
That struggle which is peculiar to all coming-to-be, that everlasting alternation of victory, is again something also described by Schopenhauer Welt als Wille and Vorstellung, Volume 1, Book 2):
Forever and ever, persistent matter must change its form. Grasping the clue of causality, mechanical, physical, chemical and organic phenomena greedily push to the fore, snatching matter from one another, for each would reveal its own inherent idea. We can follow this strife throughout the whole of nature. In fact we might say that nature exists but by virtue of it.”
