David Payne (1984)
. In a book by the author Thomas Moore, he quotes Ficino, saying, "Pythagorus asks that we not let a friend go lightly, for whatever reason. Instead, we should stay with a friend as long as we can, until we're compelled to abandon him completely against our will. It is a serious thing to toss money away, but to cast aside a person is even more serious. Nothing in human life is more rarely found, nothing more dearly possessed. No loss is more chilling or dangerous than that of a friend." Thanks to Jocelyn Bourn Doran for providing this timely quote.
