[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.

Dans toutes les professions chacun affecte une mine et un extérieur pour paraître ce qu'il veut qu'on le croie. Ainsi on peut dire que le monde n'est composé que de mines.
Variant translation: In all professions, each affects a part and an appearance to make him seem as he would wish to be believed. And so it is that one can say that the world is made only of appearances.

Speaking about soldiers in the British Army, 4 November 1813
A French army is composed very differently from ours. The conscription calls out a share of every class — no matter whether your son or my son — all must march; but our friends — I may say it in this room — are the very scum of the earth. People talk of their enlisting from their fine military feeling — all stuff — no such thing. Some of our men enlist from having got bastard children — some for minor offences — many more for drink; but you can hardly conceive such a set brought together, and it really is wonderful that we should have made them the fine fellows they are.
