I tried Gallica http://gallica.bnf.fr/ for the French equivalent, "l'ordre spontané". As
it appears, it was used by Auguste Comte in _Cours de philosophie positive_  (50e Leçon.
Considérations préliminaires sur la statique sociale, ou théorie générale de l'ordre
spontané des sociétés humaines) and in _Discours sur l'esprit positif_, and also by
Charles Fourier in his manuscripts published in _La Phalange_ .
  
Later on, the phrase occurs in M.Bakunin's article "L'Empire knouto-germanique et la
Révolution sociale". See
