What are the motifs in The Sound and the Fury by William Faulkner?

Love is a recurring idea in the novel. Mr. Compson loves his children and his wife. Quentin loves him his family and becomes very homesick in Boston away from his family. He loves his sister, Caddy, so much he risks the wrath of his father by telling him that Caddy's baby is his. He insists he committed incest to try to save his sister's reputation. Benjy loves Caddy. He could always distinguish her because to him she smells like trees. Mrs. Compson loves Jason because he is more like her than any of her children.
