"He could not do that. The people only gave him power that he might rid them of the Bourbons and because they saw that he was a great man. The Revolution was a grand thing!" continued Monsieur Pierre, betraying by this desperate and provocative proposition his extreme youth and his wish to express all that was in his mind.
The above quote. This is the conversation that Pierre has with the vicomte at Anna Pavlovna's soiree where he says that Napoleon was a great man. Can someone help me out by explaining how Pierre is betraying his extreme youth and his wish to express all that was in his mind? What does this mean? I would greatly appreciate anyone who could explain this for me. Thank you and have a nice day.
