Whenever two good people argue over principles, they are both right.

Even a stopped clock is right twice every day. After some years, it can boast of a long series of successes.

If you have one good idea, people will lend you twenty.

Oh happy pessimists! What a joy it is to them to be able to prove again and again that there is no joy.

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

In youth we learn; in age we understand.
