One of the bestest things to come of my habit to read Philosophy concurrently with someone like Faulkner, McCarthy, Marquez, Steinbeck, etc., is the accessibility of the two and how they braid together, one teaching the other in their relationship.
I have been lucky in my choices of selection and timing: Boethius with The Sound and the Fury and Child of God; Symposium and Phaedrus with their explanations of love in a time of tragedy and loneliness of As I Lay Dying.
Especially in the form of multiple points of view of Faulkner’s writing, one character has opinions of the others, becomes judgmental. Anse has been shown as hard and cold, working Addie to death and now disrespecting her by toting her body forty miles away from their own family burying ground. But all you have to do is watch Anse as he stands above her deathbed. You see the love there than transcends the here and now, just as the close forgiving love that Plato tries to set apart from the committed love of marriage. One explains the other.
It is revealing to me how much philosophy and literature reflect one another. I am just getting in to the concurrent reading approach that you mention.
