C.S Lewis uses That Hideous Strength as an allegory to explain his theses in The Abolition of Man, putting his ideas into a more literary form through the novel. Using N.I.C.E  to represent a controlling power, Lewis once again emphasizes the inherent problems with attempts to control nature because it will only create exacerbated flaws in man-kind. Lewis once again brings forth the idea of taking “over the human race” in order to “recondition it”(That Hideous Strength  39), in an attempt to make it more efficient. By definition, this act would be an attempt to overcome nature. This could be done by changing the “biochemical conditioning” by “direct manipulation of the brain”, in order to re-education the population and create “a new type of man”(40). To N.I.C.E, this would allow the eradication of the genetic unfit, creating a superior version of humans. In the Abolition of Man, Lewis hints at the extreme techniques that humans will undergo in order to conquer nature, rather than accepting nature as a part of our environment and being in a cohesive state with it. As mentioned in The Abolition of Man all of nature’s “apparent reverses” caused by men have “troubled [nature] no more”(Abolition of Man 69) than any attempt before it, and have only led to more suffering and negative consequences. This reverse of nature is the exact scenario which he illustrates in That Hideous Strength, once again standing up against the overuse of science. As Lewis explores the topic of conquering nature, his thesis that trying to do so will cause a “tyranny or an obedience”(73) which will in turn conquer man rather than nature, becomes a forefront topic in both The Abolition of Man and That Hideous Strength.
