Change alone is unchanging.
Everything flows and nothing abides, everything gives way and nothing stays fixed.
There is nothing permanent except change.
You cannot step twice into the same river, for other waters are continually flowing on.
Man's character is his fate.
A man's character is his guardian divinity.
Character is our destiny.
No one that encounters prosperity does not also encounter danger.
Men who wish to know about the world must learn about it in its particular details.
Much learning does not teach understanding.
If you do not the expect the unexpected you will not find it, for it is not to be reached by search or trail.
God is day and night, winter and summer, war and peace, surfeit and hunger.
