That Most Important Issue (According to Me)

It's hard to say which issue from That Hideous Strength is most urgent today since so many of them are still relevant today. Since I have to pick some issues, or in my case one issue, it's going to be the competition between science and religion, and their attempts to be the single entity governing humanity, and by governing I, of course, mean controlling.
Now onto the WHY.
This is the most urgent issue today, because it is a seemingly never ending competition between the two. It also appears to be going more and more in the direction of science these days. The truly interesting and urgent aspect of this competition in That Hideous Strength is that the way in which C.S. Lewis discusses the competition between the two is almost an example of how Huxley's Brave New World came about. Lewis' competition clarifies the way in which Huxley's vision could have come about, which is what makes it so urgent. Society, even now, is dealing with a competition between religion and science as the means of controlling the masses, and should either entity ever win we just might get to see a Huxleyian world.
