What men have called friendship is only a social arrangement... - Francois de La Rochefoucauld

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

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

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

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

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