Name:
Heraclitus

Dates:
Born: c. 540 BCE Died: c. 475 BCE

Biography:
Heraclitus was pre-Socratic Greek philosopher of whom we only have second-hand information. According to the reports of others, he argued that fire was the primal substance from which the universe and all matter is formed - but there does not remain any fundamental "stuff" from which everything in the universe is made.

Other preserved reports indicate that he used paradoxes to demonstrate that the world is in a constant state of flux - he even argued that the apparently unchanging hills were changing, just too slowly for people to readily notice. The most famous of these was his metaphor of the river.

Acording to Heraclitus, because a river is always flowing and always in flux, it is impossible to ever step into the same river twice. It may look to us like the same river, but obviously the water has changed entirely and continually does so from second to second. The only thing which does remain the same is the cosmic balance of everything in motion.
