"I do not think that all who choose wrong roads perish; but their rescue consists in being put back on the right road. A wrong 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 disserving power"--or else not. It is still "either-or." If we insist on keeping Hell (or even earth) we shall not see Heaven: if we acccept Heaven we shall not be able to retain even the smallest and most inanimate souveniers of Hell. I believe, to be sure, that any man who reaches Heaven will find that what he abandoned (even in plucking out his right eye) was precisely nothing: that the kernel of what he was really seeking even in his most depraved wishes will be there, beyond expectation, waiting for him in "the High Countries." In that sense it will be true for those who have completed the journey (and for no others) to say that good is everything and Heaven in everywhere. But we, at this end of the road, must not try to anticipate that retrospective vision. If we do, we are likely to embrace the false and disasterous converse and fancy that everything is good and everywhere is Heaven.
But what, you ask, of earth? Earth, I think, will not be found by anyone to be inthe end a very distinct place. I think earth, if chosen instead of Heaven, will turn out to have been, all along, only a region in Hell: and earth, if put second to Heaven, to have been from the beginning a part of Heaven itself."
