Adverting to the usual example of the love of money, he remarks that
the benevolent man might begin with an interested affection, but might
end with a disinterested delight in doing good. Self-love, or the
principle of permanent well-being, is gradually formed from the
separate appetites, and is at last pursued without having them
specially in view. So Sympathy may perhaps be the transfer, first, of
our own personal feelings to other beings, and next, of their feelings
to ourselves, thereby engendering the social affections. It is an
ancient and obstinate error of philosophers to regard these two
principles--Self-love and Sympathy--as the _source_ of the impelling
passions and affections, instead of being the last results of them.
