New happiness too must be learned to bear.

One has to do good in order for it to exist in the world.

One remains young as long as one can still learn, can still take on new habits, can bear contradictions.

That bad manners are so prevalent in the world is the fault of good manners.

We are so vain that we even care for the opinion of those we don't care for.

Nowadays people are born to find fault. When they look at Achilles, they see only his heel.

Little evil would be done in the world if evil never could be done in the name of good.
