Though the most different book from his space trilogy, That Hideous Strength by C.S. Lewis is an important part of the narrative within the trilogy. Whereas Out of the Silent Plant and Paralandra spoke of the battle of good and evil in distant space, That Hideous Strength presents the same battle happening on earth. This narrative poses a question of readers in a way that the others did not, asking them how they will respond to the battle happening in their home world. In doing so, Lewis presents a case on the nature of man and his influence over destiny.

Presented at the 1997 Frances White Ewbank Colloquium.
