Jealousy is not love, but self-love.

The reason we do not let our friends see the very bottom of our hearts is not so much distrust of them as distrust of ourselves.

Unfaithfulness ought to extinguish love, and we should not be jealous when there is reason to be. Only those who give no grounds for jealousy are worthy of it.

The measure of great men should always be measured by the means they have used to acquire it.

If we did not flatter ourselves, the flattery of others could never harm us.

We often see malefactors, when they are led to execution, put on resolution and a contempt of death which, in truth, is nothing else but fearing to look it in the face--so that this pretended bravery may very truly be said to do the same good office to their mind that the blindfold does to their eyes.

The principal point of cleverness is to know how to value things just as they deserve.
