There is not a great deal in common between Edgar Rice Burroughs and CS Lewis, between John Carter, saviour of Barsoom, and Aslan, saviour of Narnia. However, we discuss both ERB and CSL in relation to Poul Anderson because Anderson bridges that yawning chasm: sword-wielding heroes in his heroic fantasies and theological concerns in "The Problem of Pain," a title shared with CSL, and The Game Of Empire. Indeed, Aslan is a leonine incarnation in Narnia while Anderson's Father Axor seeks evidence of an alien incarnation elsewhere in this galaxy.
We have recently looked at politics on ERB's Barsoom, in Anderson's Technic civilization and in some other fictional realms and also at speculations about time in the works of Anderson, Blish, Stirling and Lewis.
In Britain, we are at an interesting pause before, potentially, a historical turning point. It can all go wrong - but life is very wrong already.
Later: It occurs to me that there are sword fights in Narnia but, of course, we also refer to other CSL works like The Great Divorce.
