"He thinks that Schiller and St Paul were just two Partisan Review editors"

This quote by Randall Jarrell is an amusing jab at the intellectualism of the literary world. By comparing 2 of the most prominent figures in Western literature, Friedrich Schiller and Saint Paul, to 2 editors of the Partisan Review, Jarrell is suggesting that the literary world has actually become too concentrated on the viewpoints of a couple of intellectuals. He is recommending that the viewpoints of these intellectuals have actually become so crucial that they are being compared to some of the most influential figures in history. This quote is a funny way of pointing out the absurdity of the literary world's obsession with the viewpoints of a few intellectuals.
