If we wish to know about a man, we ask 'what is his story--his real, inmost story?'--for each of us is a biography, a story. Each of us is a singular narrative, which is constructed, continually, unconsciously, by, through, and in us--through our perceptions, our feelings, our thoughts, our actions; and, not least, our discourse, our spoken narrations. Biologically, physiologically, we are not so different from each other; historically, as narratives--we are each of us unique.
Literature is not exhaustible, for the sufficient and simple reason that a single book is not. A book is not an isolated entity: it is a narration, an axis of innumerable narrations. One literature differs from another, either before or after it, not so much because of the text as for the manner in which it is read.
I get the impression from some people that unless they get direct access to characters' thoughts and realizations, either through thought balloons or narrations or some sort of showy action, then those thoughts and realizations never existed.
