"Whosoever wishes to know about the world
must learn about it in its particular details.
Knowledge is not intelligence.
In searching for the truth be ready for the unexpected.
Change alone is unchanging.
The same road goes both up and down.
The beginning of a circle is also its end.
Not I, but the world says it: all is one.
And yet everything comes in season."
Heraclitus (more quotes by Heraclitus or books by/about Heraclitus)
(c.540-480 BC) Greek philosopher
