I believe, to be sure, that any man who reaches Heaven will find that what he abandoned (even in plucking out his right eye) has not been lost: 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 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 disastrous 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 in the 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.
