Maybe I have missed some earlier posting, but there seems to have been yet no mention of a third occurrence of the 'invisible hand' in Smith (chronologically, the first), in the history of astronomy, where he discusses how people used to invoke Jupiter's invisible hand to explain phenomena they could not understand otherwise. For a discussion along this line, seeing also the later uses of the metaphor in this connection, see J. B. Davis, ?Smith?s Invisible Hand and Hegel?s Cunning of Reason?, in International Journal of Social Economics, 1989; ?Adam Smith?s four Invisible Hands?, by S.Ahmad, in HOPE, 22:1, 1990; and, for those who can read Italian, A. M. Iacono, ?Adam Smith e la metafora della ?mano invisibile??, in L?evento e l?osservatore. Ricerche sulla storicit? della conoscenza, Bergamo: Lubrina, 1987; and S. Fiori, Ordine, mano invisibile e mercato (Torino: Utet, 2001). Daniele Besomi
