The heart is forever making the head its fool.

Self-love is the greatest of all flatterers.

A certain harmony should be kept between actions and ideas if we want to fully develop the effects they can produce.

Neither love nor fire can subsist without perpetual motion; both cease to live so soon as they cease to hope, or to fear.

Our desires always disappoint us; for though we meet with something that gives us satisfaction, yet it never thoroughly answers our expectation. [However disappointment can always be removed if we remember it could have turned out worse.]

We should wish for few things with eagerness, if we perfectly knew the nature of that which was the object of our desire.

There is a sort of love whose very excessiveness prevents the lover's being jealous.
