This work investigates the theological and philosophical underpinnings of C.S. Lewis’s Space Trilogy to determine how the author integrated his Christian worldview into the science fiction genre. Walter Hooper, a long-time secretary and literary executor for Lewis, utilizes his intimate knowledge of the author’s personal papers and correspondence to map the development of the trilogy. The text argues that the series serves as a deliberate counter-narrative to the secular, materialist science fiction prevalent in the mid-20th century.

Scholars and readers frequently cite this work as a primary resource for understanding the intellectual intent behind Lewis’s fiction. Experts highlight the text for its clarity and its success in bridging the gap between Lewis’s academic theology and his creative storytelling.
