In the preface to The Great Divorce, C.S. Lewis writes:
“Blake wrote the Marriage of Heaven and Hell... The attempt is based on the belief that reality never presents us with an absolutely unavoidable ‘either-or’; that granted skill and patience and (above all) time enough, some way of embracing both alternatives can always be found; that mere development or adjustment or refinement will somehow turn evil into good without our being called on for a final and total rejection of anything we should like to retain. This belief I take to be a disastrous error.”
“I do not think that all who choose wrong roads perish; but their rescue consists in being put back on the right road. A sum can be put right: but only by going back till you find the error and working it afresh from that point, never by simply going on. Evil can be undone, but it cannot ‘develop’ into good. Time does not heal it. The spell must be unwound, bit by bit, ‘with backward mutters of disservering power’ –or else not at all.”
