We are never so generous as when giving advice.

If there be a love pure and free from the admixture of our other passions, it is that which lies hidden in the bottom of our heart, and which we know not ourselves.

Jealousy is bred in doubts. When those doubts change into certainties, then the passion either ceases or turns absolute madness.

We would rather speak ill of ourselves than not talk about ourselves at all.

Great souls are not those who have fewer passions and more virtues than others, but only those who have greater designs.

Generosity is the vanity of giving.

The violence we do to ourselves in order to remain faithful to the one we love is hardly better than an act of infidelity.
