Abraham Lincoln:
How many legs does a dog have if you call the tail a leg? Four; calling a tail a leg doesn't make it a leg.
Abraham Lincoln:
Truth is generally the best vindication against slander.
Heraklietos of Ephesos:
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.
