In friendship as well as love, ignorance very often contribu... - Francois de La Rochefoucauld

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

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

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

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

"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."
