About Heraclitus
Heraclitus of Ephesus (circa 535–475 BCE) was a pre-Socratic Greek philosopher known for his enigmatic sayings and profound insights into the nature of change and existence. Often referred to as the "Weeping Philosopher," he famously posited that "everything flows" (panta rhei), emphasizing the constant state of flux in the universe, and he introduced the concept of the unity of opposites. His thoughts on fire as a fundamental element and the logos as a guiding principle laid important groundwork for later philosophical and scientific developments.
