About Heraclitus
Heraclitus, a pre-Socratic philosopher from Ephesus, flourished around 500 BCE and is best known for his doctrine that change is central to the universe, encapsulated in the phrase "everything flows." He famously asserted that "you cannot step into the same river twice," emphasizing the permanence of change and the interconnectivity of opposites. His enigmatic writings, often focusing on the unity of opposites and the constant state of flux, have influenced various philosophical schools, including Stoicism and existentialism.
