Heraclitus (of Ephesus ). Books

Heraclitus of Ephesus was a pre-Socratic Greek philosopher renowned for his assertion that constant change is the fundamental essence of the universe. He championed the unity of opposites, positing that all things exist in pairs of contrary properties, and famously stated that "no man ever steps in the same river twice." His philosophy, often perceived as cryptic and paradoxical, coupled with his emphasis on humanity's inherent unawareness, earned him the epithets "The Obscure" and the "Weeping Philosopher." His profound concept of the Logos, governing all existence, continues to be a subject of deep interpretation.
