Most likely the similarities you see here are all the result of classicists (and likely Jaynes) reading Bruno Snell. Snell's most famous work was Die Entdeckung des Geistes, which posited that the integrated self was a recent development of the archaic age of Greece. Snell's theory, which drew heavily on art history, has not fared well given the discovery of much more advanced Minoan art.
