Heraclitus of Ephesus (l. c. 500 BCE) was one of the early Pre-Socratic philosophers who, like the others, sought to identify the First Cause for the creation of the world. He rejected earlier theories such as air and water and claimed that fire was the First Cause as it both created and destroyed.
