“In narratives involving irrational and obsessive hatred, especially of some person or group one doesn’t really know very well, “such hatred” say the Jungians, is the mark of a person who has not come to terms with his or her own Shadow. The Shadow is our dark side, the repository of everything in us we’re ashamed of and would rather not acknowledge, and also of those qualities we profess to despise but would in fact like to possess. If we haven’t acknowledged those things about ourselves, we’re likely to project them onto somebody else or some other group, and to develop an irrational hatred toward that person or group. In fiction, the Shadow often appears as an actual double or twin or replicant, as in Poe’s story “William Wilson” or Oscar Wilde’s The Picture of Dorian Gray.”
