Heraclitus is Born
Heraclitus of Ephesus (Ancient Greek: Ἡράκλειτος ὁ Ἐφέσιος — Hērákleitos ho Ephésios; c. 535–c. 475 BCE) was a pre-Socratic Greek philosopher, a native of Ephesus, Ionia, on the coast of Asia Minor.
He was of distinguished parentage. Little is known about his early life and education, but he regarded himself as self-taught and a pioneer of wisdom. From the lonely life he led, and still more from the riddling nature of his philosophy and his contempt for humankind in general, he was called "The Obscure," and the "Weeping Philosopher."
Heraclitus is famous for his doctrine of change being central to the universe, as stated in his famous saying, "You can not step twice into the same river." He believed in the unity of opposites, stating that "the path up and down is one and the same," existing things being characterized by pairs of contrary properties. His cryptic utterance that "all things come to be in accordance with this Logos," (literally, "word," "reason," or "account") has been the subject of numerous interpretations.
This Logos holds always but humans always prove unable to understand it, both before hearing it and when they have first heard it. For though all things come to be in accordance with this Logos, humans are like the inexperienced when they experience such words and deeds as I set out, distinguishing each in accordance with its nature and saying how it is. But other people fail to notice what they do when awake, just as they forget what they do while asleep.”— Heraclitus
