Joseph Campbell's Dark Materials

Joseph Campbell was an ardent Jungian scholar, best known for his book The Hero with a Thousand Faces, which details how Jung's archetypes of the collective unconscious are manifested in every single work of literature, or even of orality. Every story has at least these three basic archetypes: the Self, the Anima/Animus, and the Shadow. His Dark Materials is no different from any other story in this regard. Lyra represents the Self since she is the main character, who undergoes the most enlightenment and changes, and whose consciousness is reflected in the layout of the other characters. The Anima reflects the Self's gender and general ideas, in Lyra's case, Mrs. Coulter. Although she would seem to be the Shadow if one had not read the entire book, ultimately she helps Lyra's cause, and mirrors her thoughts and feelings. For example, she actually saves Lyra's life three times, and she sacrifices herself at the end of the book, along with Lord Asriel, for the furthering of Lyra's cause, to overthrow The Authority. The Shadow is represented by The Authority and Megatron, which metaphorically represents all the bad excesses of Christianity that need to be shed off: the superficial bullshit, as the Pope calls it.
