The world-view which informs Perelandra (1943) in particular and the so-called “space trilogy” more generally, of which it is the second volume, is deeply infused with that blend of Christianity and Platonism that is the hallmark of the thought of C. S. Lewis and which I explore at some length in the companion essay to this piece in this volume, “The Neoplatonic Christianity of C. S. Lewis.” Perelandra is, I would argue, a literary rendition of some of the most important philosophical arguments in defense of Christianity mounted by Lewis in Mere Christianity and elsewhere.
