Francois de La Rochefoucauld

"When we are in love we often doubt that which we most believe."

"No persons are more frequently wrong, than those who will not admit they are wrong."

"There is only one kind of love, but there are a thousand imitations."

"There is no disguise which can hide love for long where it exists, or simulate it where it does not."

"Hope, deceiving as it is, serves at least to lead us to the end of our lives by an agreeable route."

"True love is like ghosts, which everyone talks about and few have seen."

"In friendship as well as love, ignorance very often contributes more to our happiness than knowledge."

"Neither the sun nor death can be looked at steadily."

"What men have called friendship is only a social arrangement, a mutual adjustment of interests, an interchange of services given and received; it is, in sum, simply a business from which those involved propose to derive a steady profit for their own self-love."

"Jealousy contains more of self-love than of love."

"A true friend is the greatest of all blessings, and that which we take the least care of all to acquire."

"Neither the sun nor death can be looked at steadily."

"No persons are more frequently wrong, than those who will not admit they are wrong."

"True love is like ghosts, which everybody talks about and few have seen."

"If we are to judge of love by its consequences, it more nearly resembles hatred than friendship."

"It is easier to be wise for others than for ourselves."

"We promise according to our hopes and perform according to our fears."

"However rare true love may be, it is less so than true friendship."
