And I have again observed, my dear friend, in this trifling affair, that misunderstandings and neglect occasion more mischief in the world than even malice and wickedness. At all events, the two latter are of less frequent occurrence.

Few people have the imagination for reality.

With knowledge comes more doubt.

To become aware in time when young of the advantages of age; to maintain the advantages of youth in old age: both are pure fortune.

Only by joy and sorrow does a person know anything about themselves and their destiny. They learn what to do and what to avoid.

The older we get the more we must limit ourselves if we wish to be active.

We know accurately only when we know little, with knowledge doubt increases.
