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

All things flow, nothing abides. You cannot step into the same river twice, for the waters are continually flowing on. Nothing is permanent except change.

Things of which there is sight, hearing, apprehension, these I prefer.

To do the same thing over and over again is not only boredom: it is to be controlled by rather than to control what you do.

It is in changing that things find purpose.

Eyes are more accurate witnesses than ears.

Greater dooms win greater destinies.
