Context

“We might say that he acquires the ways of society just because he cares so little about them. But do not make any mistake as to his bearing; it is not to be compared with that of your young dandies. It is self-possessed, not conceited; his manners are easy, not haughty; an insolent look is the mark of a slave, there is nothing affected in independence. I never saw a man of lofty soul who showed it in his bearing; this affectation is more suited to vile and frivolous souls, who have no other means of asserting themselves. I read somewhere that a foreigner appeared one day in the presence of the famous Marcel, who asked him what country he came from.” source
