Extract from a letter to Bede Griffiths, with whom Lewis shares an insight from The Great Divorce (Chapter 9), which he was writing at the time:
25 May 1944
Thanks for your letter. I too was delighted with our meeting. About the past, and nothing being lost, the point is that ‘He who loses his life shall save it' is totally true, true on every level. Everything we crucify will rise again: nothing we try to hold onto will be left us.
I wrote the other day ‘Good and evil when they attain their full stature are retrospective. That is why, at the end of all things, the damned will say we were always in Hell, and the blessed we have never lived anywhere but in heaven.’ Do you agree?
You’re right about C.W. He has an undisciplined mind and sometimes admits into his theology ideas whose proper place is in his romances. What keeps him right is his love of which (and I have now known him long) he radiates more than any man I know. . . . Continue to pray for me as I do for you.
