STREAM-THING

Row, row, row your boat,
Gently down the stream.
Merrily, merrily, merrily, merrily,
Life is but a dream.

Heraclitus, I believe, says that all things pass and nothing stays, and comparing existing things to the flow of a river, he says you could not step twice into the same river.

—Plato :: Cratylus

In the same river we both step and do not step,
we are and are not.
Potamoisi toisin autoisin embainousin
hetera kai hetera hudata epirrei.

—Heraclitus

All things move like flowing streams.

—Plato :: Theaetetus

Ol' man river,
Dat ol' man river
He mus'know sumpin'
But don't say nuthin',
He jes'keeps rollin'
He keeps on rollin' along.

—Oscar Hammerstein

Croesus was at a loss how his army would cross the river, it is said that, since, in fact, there did not yet exist during that time those bridges, Thales, being present in the camp, brought about for him that the river, which flowed on the left side of the army, flowed also on the right, and brought it about this way: beginning further upstream than the camp, he dug a deep trench and drew it moon-shaped, that the river might get the camp set up behind itself, when it was diverted by that route through the trench from its ancient streams, and again, when it passed by the camp, might enter into its ancient streams. And so, as soon as the river had actually split, it became fordable in both places.

—Herodotus :: Histories I

Many waters cannot quench love,
neither can the floods drown it...

—Song of Solomon 08:07
