Quote by Heraclitus: “No man ever steps in the same river twice, for it's not the same river and he's not the same man.”

This famous quote illustrates the constant, unavoidable nature of change in both the external world and within ourselves. It implies that every moment is unique and transient, urging an acceptance of life's perpetual flow and transformation, as nothing ever stays the same.

Heraclitus, a pre-Socratic Greek philosopher (c. 535 – c. 475 BCE), lived in a world where foundational concepts of existence were being fiercely debated. His philosophy challenged static views of reality, positing that constant flux was the fundamental truth of the cosmos, influencing later Stoics and Existentialists.

Greek philosopher from Ephesus, active around 500 BCE, known for his doctrine that change is the fundamental nature of the universe. His surviving work exists only in fragments quoted by later writers. He was called 'the Obscure' by ancient commentators for his cryptic, aphoristic style.
