Virtue would not go nearly so far if vanity did not keep her company.

When our vices leave us, we flatter ourselves that we leave them.

The most violent passions sometimes leave us at rest, but vanity agitates us constantly.

No one has ever taken the trouble to stretch and carry his understanding as far as it could go.

There is an eloquent silence: it serves sometimes to approve, sometimes to condemn.

The passions are the only orators which always persuade.

We should often feel ashamed of our best actions if the world could see all of the motives which produced them.

If we judge of love by its usual effects, it resembles hatred more than friendship.

Jealousy is always born with love but does not always die with it.

Too great haste in paying off an obligation is a kind of ingratitude.
