"there have ever been and will ever be men who, after having submitted some portion of their religious belief to the principle of authority, will seek to exempt several other parts of their faith from it and to keep their minds floating at random between liberty and obedience. But I am inclined to believe that the number of these thinkers will be less in a democratic than in other ages, and that our posterity will tend more and more to a division into only two parts, some relinquishing Christianity entirely and others returning to the Church of Rome."

André Jardin (Bibliothèque de la Pléiade), II (De la démocratie en Amérique), ed. Jean-Claude Lamberti and James T. Schleifer (Paris: Éditions Gallimard, 1992), 540. Note on p. 1096 of the latter speaks to the originality of this thesis by comparison with that of (say) Michel Chevalier (Lettres sur l'Amérique du Nord), for whom "Catholicism is the religion naturally associated with the monarchy".
