Night-Sea Journey, John Barth

"One way or another, no matter which theory of our journey is correct, it's myself I address; to whom I rehearse as to a stranger our history and condition, and will disclose my secret hope though I sink for it.
 "Is the journey my invention? Do the night, the sea, exist at all, I ask myself, apart from my experience of them? Do I myself exist, or is this a dream? Sometimes I wonder. And if I am, who am I? The Heritage I supposedly transport? But how can I be both vessel and contents? Such are the questions that beset my intervals of rest.
