Everything should be made as simple as possible, but not simpler.

Not everything that counts can be counted, and not everything that can be counted counts.

Patience serves us against insults precisely as clothes do against the cold. For if you multiply your garments as the cold increases, that cold cannot hurt you; in the same way increase your patience under great offenses, and they cannot hurt your feelings.

Where there is shouting, there is no true knowledge.
