Desiree's Baby by Kate Chopin

Armand sees himself as superior. He believes himself to be a proud, white man, who is superior to his slaves when in actuality he has African-American ancestors—this illustrates capricious nature of naming, categorizing, and judging people based on their family name, appearance, or other characteristics. When Armand believes his wife to be of African-American heritage, he insists that she leave his home.... that his name has been besmirched through the birth of their child.
