Disinterested

"Tis folly in one Nation to look for disinterested favors from another; that it must pay with a portion of its Independence for whatever it may accept under that character; that by such acceptance, it may place itself in the condition of having given equivalents for nominal favours and yet of being reproached with ingratitude for not giving more. There can be no greater error than to expect, or calculate upon real favours from Nation to Nation. 'Tis an illusion which experience must cure, which a just pride ought to discard."
--George Washington (Farewell Address, 19 September 1796)
