Here's one on faith from the same author that requires a couple readings to get past the old school English...at least it did for me.
All Faith is false, all Faith is true:
Truth is the shattered mirror strown
In myriad bits; while each believes
His little bit the whole to own.
Sir Richard Francis Burton
Then this other one applies to us all here at SR, I'd say.
Conquer thyself, till thou has done this, thou art but a slave; for it is almost as well to be subjected to another's appetite as to thine own.
Sir Richard Francis Burton
