The man

πάντα ῥεῖ. Everything flows. Everything moves. Makes way. Changes. Is in flux.

πάντα ῥεῖ or Panta Rei, is a statement in ancient Greek attributed to the philosopher Heraclites. The statement means ‘Everything Flows’. 

Not much is known of Heraclitus of Ephesus, a key figure in philosophy, thought to have lived around 500 BC, and lovingly called ‘the weeping philosopher’. We have none of his original texts to study, no real account of his life, other than the words other key figures such as Plato have prescribed to him. The river analogy might be his most famous, now known in popular culture as the statement ‘You can never step into the same river twice’.
