The fifth C. S. Lewis conference focuses on C. S. Lewis and his literary and academic kin as creators of worlds. His entire work testifies to his fascination with alternative universes, from his scholarly exploration of Medieval literature, with its haunting myths and arcane symbolism, through his fiction, to his apologetics, where Christianity is seen as a parallel kingdom seeking to be reinstated in “an enemy-occupied territory”. From pain to love, through faith and imagination, he opened a spectrum of realities inviting exploration and reflection. The collection of essays by Lewis alluded to in the title of this year’s conference spans both this and other worlds: “this” realm, which we inhabit, is the necessary, unavoidable starting point for any explorers, conquerors, pilgrims, even refugees into the “others”.
