It was my care to make my life illustrious not by words more than by deeds.

All that is not eternal is eternally out of date.

Don't part with your illusions. When they are gone you may still exist, but you have ceased to live.

The happiest is the person who suffers the least pain; the most miserable who enjoys the least pleasure.
