" You cannot step into the same river twice."
Heraclitus of Ephesus was a pre-Socratic Greek philosopher, and a native of the city of Ephesus, then part of the Persian Empire. 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 apparently riddled and allegedly paradoxical nature of his philosophy and his stress upon the needless unconsciousness of humankind,he was called "The Obscure" and the "Weeping Philosopher".
