Disinterestedness of Friendship
In friendship, there is no commerce or business depending on the same, but itself.
Montaigne
You must therefore love me, myself, and not my circumstances, if we are to be real friends.
Cicero
I can never think of promoting my convenience at the expense of a friend's interest and inclination.
George Washington
There is possible to-day, as ever, a generous friendship which forgets self.... The miracle of friendship has been too often enacted on this dull earth of ours to suffer us to doubt either its possibility or its wondrous beauty.
