Virtue would go far if vanity did not keep it company.

Tastes in young people are changed by natural impetuosity, and in the aged are preserved by habit.

Generosity is the vanity of giving.

The reason we bitterly hate those who deceive us is because they think they are cleverer than we are.

We are sometimes as different from ourselves as we are from others.

Almost everyone takes pleasure in repaying trifling obligations, very many feel gratitude for those that are moderate; but there is scarcely anyone who is not ungrateful for those that are weighty.

We should desire very few things passionately if we did but perfectly know the nature of the things we desire.
