Men are not only prone to forget benefits; they even hate those who have obliged them, and cease to hate those who have injured them. The necessity of revenging an injury, or of recompensing a benefit seems a slavery to which they are unwilling to submit.

We are deceived if we think that mind and judgment are two different matters: judgment is but the extent of the light of the mind. This light penetrates to the bottom of matters; it remarks all that can be remarked, and perceives what appears imperceptible. Therefore we must agree that it is the extent of the light in the mind that produces all the effects which we attribute to judgment.

A man often believes himself leader when he is led; as his mind endeavors to reach one goal, his heart insensibly drags him towards another.

In love deceit almost always outstrips distrust.

Few are sufficiently wise to prefer censure which is useful to praise which is treacherous.

Gratitude is merely the secret hope of further favors.
