Jean Dhombres, a mathematician and historian of mathematics (he has edited Laplace's lectures at Ecole normale) writes that Saint Simon criticized Laplace in Histoire de l'Homme, 1809-1811. <http://www.geisteswissenschaften.fu-berlin.de/v/grammaire_generale/Actes_du_colloque/Textes/Dhombres/index.html>http://www.geisteswissenschaften.fu-berlin.de/v/grammaire_generale/Actes_du_colloque/Textes/Dhombres/index.html Dhombres' presentation of Saint-Simon's case against Laplace is related to some Hayek's topics about social order. Moreover the dates fit pretty well you calendar, aren't they? I have not Saint-Simon's book at hand and I should visit a library to morrow if noboby has a better reference till then. regards Alain Alcouffe
