I would agree with the observation of one theologian that, “literature… originates in the most irreducible core of the person, that mysterious level [of their being]… Literature is life, conscious of itself, that reaches its full self-expression through the use of all the conceptual resources of language”. 

Literature (such as Granny Barkes Fell in Woolworths) thus has to do, in one way or another, with our deepest desires in this life, for on a profound level literature engages our concrete existence, with its innate tensions, desires and meaningful experiences.

POPE FRANCIS
