Heraclitus was a pre-Socratic philosopher from the Greek city of Ephesus.

He lived during the 6th century BC in Ionia. At that time, Ephesus was a major port on the Cayster River. The city was part of the Persian Empire. Heraclitus had a massive influence on Western philosophy. His ideas reached thinkers like Plato and Aristotle. Later, he influenced the Stoics and modern philosophers like Nietzsche and Heidegger.

Heraclitus is best known for his ideas about change and opposites. He believed the world was in a constant state of flux. This means everything is always moving or becoming something new. He famously said, "Everything flows."

He also said that "No man ever steps in the same river twice." This illustrates that the water and the man are always changing. He believed fire was the arche, or the fundamental substance of the world.

He also taught that the logos provided structure to the universe. The logos is a term for reason, word, or divine law.

His philosophy focused on the unity of opposites. This is the idea that opposing forces actually work together. He saw harmony and justice within strife. For example, he noted that the way up and the way down are the same. He believed that beginning and end meet on a circle's circumference. Some scholars, including Aristotle, suggested Heraclitus was a dialetheist. This means he might have denied the law of noncontradiction. This principle usually states that something cannot be both true and false at once.

We know very little about Heraclitus's actual life. Most of our information comes from the writer Diogenes Laërtius. Some stories suggest Heraclitus was from an aristocratic family. He may have given up a hereditary title of "king" to his brother. However, many ancient stories might be later fabrications. He was often described as a solitary and arrogant man. Some called him a misanthrope, which means someone who dislikes people. Because of his perceived sadness, he was called "the weeping philosopher." This stood in contrast to Democritus, who was "the laughing philosopher."

Heraclitus wrote a single work, likely titled "On Nature."

He reportedly deposited this book in the Artemision, a temple in Ephesus.

Today, the original papyrus is lost. We only have over 100 fragments of his work. These fragments survive because other authors quoted him. By the 6th century, his work was already becoming rare. Even the philosopher Simplicius mentioned him many times without having a copy to quote. His writing was very dense and used many literary devices.

His style was often called "obscure" or "dark."

He used wordplay, alliteration, and chiasmus to express his ideas. Some thinkers believed he wrote this way on purpose. They thought he wanted to challenge only the most capable readers. He used cryptic, oracular epigrams that sounded like riddles. This earned him the nickname "the Riddler." Even Socrates remarked that understanding his work required a "Delian diver" to reach the bottom. His goal was to make people seek truth within themselves.

Heraclitus's ideas created a major contrast in ancient thought. He focused on constant change and flux. This was the opposite of Parmenides, who believed reality was static and unchanging.

While the Milesian philosophers before him chose water or air as the arche, Heraclitus chose fire. His work connects to many different fields today. Scholars study him as a materialist, a cosmologist, and a metaphysician. He remains a central figure in the history of how humans understand the nature of existence.
