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.
HeraclitusThe opposite is beneficial; from things that differ comes the fairest attunement; all things are born through strife.
HeraclitusEverything changes but change itself. Everything flows and nothing remains the same... You cannot step twice into the same river, for other waters and yet others go flowing ever on.
