The term bourgeois I use following Flaubert, not Marx. Bourgeois in Flaubert’s sense is a state of mind, not a state of pocket. A bourgeois is a smug philistine, a dignified vulgarian. … The character I have in view when I say “smug vulgarian” is, thus, not the part-time philistine, but the total type, the genteel bourgeois, the complete universal product of triteness and mediocrity. He is the conformist, the man who conforms to his group, and he also is typified by something else: he is a pseudo-idealist, he is pseudo-compassionate, he is pseudo-wise.
