As to Smith's invisible hands (three, not one, as pointed out by John
Medaille; or even four …) see J. B. Davis, “Smith’s Invisible Hand and
Hegel’s Cunning of Reason”, in International Journal of Social
Economics, 1989;  S. Ahmad,  “Adam Smith’s four Invisible Hands”, in
History of Political Economy, 22:1, 1990. And, for those who can read
Italian, the brilliant A. M. Iacono, “Adam Smith e la metafora della
‘mano invisibile’”, in L’evento e l’osservatore. Ricerche sulla
storicità della conoscenza, Bergamo: Lubrina, 1987.
