What is the author's tone in Remembrance of Things Past by Marcel Proust?

The language and tone serves to show the narrator's idealization of the aristocracy while exhibiting the aristocracy's snobbishness to the lower classes. This is further highlighted through Saint-Loup's tendency to speak more like the narrator's grandmother, who does not disdain any class of people; Saint-Loup and Grandmother are more open-minded to everyone.
