I wonder whether, in the history of all the civilisations that have ever been, a more insanely optimistic notion has ever been entertained than that you and I, mortal, puny creatures, may yet aspire, with God’s grace and Christ’s help, to be reborn into what St Paul calls the glorious liberty of the children of God. Or if there was ever a more abysmally pessimistic one than that we, who reach out with our minds and our aspirations to the stars and beyond, should be able so to arrange our lives, so to eat and drink and fornicate and learn and frolic, that our brief span in this world fulfils all our hopes and desires.
