Book excerpt: Sanford Schwartz offers a penetrating new reading of Lewis's celebrated Space Trilogy. Taken together, Schwartz's readings call into question Lewis's self-styled image as a "dinosaur" out of step with the main currents of modern thought. Far from a simple struggle between an old-fashioned Christian humanism and a newfangled heresy, Lewis's Space Trilogy should be seen as the searching effort of a modern religious apologist to sustain and enrich the former through critical engagement with the latter.
