No man ever steps in the same river twice, for it's not the same river and he's not the same man.

Because it is so unbelievable, the Truth often escapes being known.

There is nothing permanent except change. Nothing is permanent except change. The only constant is change. Change is the only constant. Change alone is unchanging.

Eternity is a child playing, playing checkers; the kingdom belongs to a child.

A blow to the head will confuse a man's thinking, a blow to the foot has no such effect, this cannot be the result of an immaterial soul.

The river where you set your foot just now is gone-those waters give way to this, now this.

He who hears not me but the logos will say: All is one.
