In the Disney movie Pocahontas, the titular character sings about the river in Just around the River Bend:
[Pocahontas] What I love most about rivers is: You can't step in the same river twice The water's always changing, always flowing But people, I guess, can't live like that We all must pay a price To be safe, we lose our chance of ever knowing
Was this an intentional quotation from the works of the Greek philosopher Heraclitus, or was this merely a coincidence on the part of the Disney songwriters, perhaps sourced from Native American philosophy?
"Everything changes and nothing remains still ... and ... you cannot step twice into the same stream"
