Philosophers
Heraclitus
Born in Ephesus in Asia Minor around the 6th century BCE, Heraclitus was a pre-Socratic philosopher who proposed the doctrine of universal flux and the concept of logos as the rational principle governing all change. His vision that opposites are interdependent laid the foundations of dialectical thinking. Called 'the Obscure' for his deliberately enigmatic style, he profoundly influenced the Stoics, Hegel, and Nietzsche.
