Not I but the world says it: All is one.
There is nothing permanent in the world except change.
The nature of things is in the habit of concealing itself.
Men who wish to know about the world must learn about it in its particular details.
If one does not expect the unexpected, one will not find it out, since it is not to be searched out, and difficut to compass.
Day by day, what you do is who you become.
