"However rare true love may be, it is less so than true friendship."
"Neither the sun nor death can be looked at steadily."
"A true friend is the greatest of all blessings, and that which we take the least care of all to acquire."
"In friendship as well as love, ignorance very often contributes more to our happiness than knowledge."
"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."
