[J]e me propose en m'adressant à différentes fractions de l'humanité, que je divise en trois classes: la première, celle à laquelle vous et moi avons l'honneur d'appartenir, marche sous l'étendard des progrès de l'esprit humain; elle marche sous l'étendard des progrès de l'esprit humain; elle est composée des savants, des artistes et de tous les hommes qui ont des idées libérales. Sur la bannière de la seconde il est écrit: point d'innovation; tous les propriétaires qui n'entrent point dans la première sont attachés à la seconde. La troisième, qui se rallie au mot égalité, renferme le surplus de l'humanité.
