As is the tendency with all powerful ideas, Lewis's arguments have become a rhetorical talisman, an epistemological panacea. Because they offer a number of compelling insights that strike at the root of important questions, they are taken to resolve all root matters. Therefore, however new the wineskins, readers of popular evangelical apologetics end up drinking some version of that sound old Oxford vintage.
The result of this Lewis-worship is a two-fold narrowing of evangelical intellectual life. First, as Lewisian thought becomes the discursive structure of critical inquiry, it ceases to be the object of critical inquiry. Lewis is never put in the dock for inspection, revision, abandonment or refinement. Lewis is the dock.
Second, an evangelical milieu that so prides itself on its "engagement" with secular thought and culture begins to count reading and rehearsing Lewisian argument as such engagement. "Engagement" thus becomes a second-hand affair -- synonymous with finding out what C.S. Lewis has said on a given topic. But the 21st century has some new topics; and while it is unwise to execute some great divorce with the past and its great thinkers, each generation must write its own books.
Lewis certainly has had an influence on me and I openly admit that when making arguments about the need to put forth coherent statements about ultimate values, that I am channeling Lewis. That being said I see myself as engaging in a conversation with Lewis, a conversation that goes to different places. For me, the bigger issue than just trying to make moral statements is trying to pass those statements on to one's children. (See "When Lesbian Nazis in Bell-Bottoms Attack.") Perhaps this is because Lewis lived in a world in which even his atheists were still deeply in touch with a traditional culture. I live several generations down this path and worry when the heritage of the Enlightenment, based ultimately on early modern Christian thought, will finally run out on us.
This problem posed by Harper needs to be taken a step further. Yes, Lewis was a powerful writer. That the evangelical community has an unhealthy relationship with him I think, though, is due to the fact that it has yet to produce a writer who can match him. Perhaps this is the true scandal of the evangelical mind. Forget about being able to match secular academic culture; it has yet to match C. S. Lewis. Thus the theological conversation never moves beyond Lewis. Readers have nothing better to read than Lewis as writers are not capable of doing anything but reproducing Lewis.
I would go so far with this as to make a comparison to Orthodox Judaism and R. Samson Raphael Hirsch. Hirsch, a nineteenth-century German rabbi, was certainly the Jewish writer that most influenced me as a teenager and college student. Now as Dr. Alan Brill once pointed out to his class, Hirsch as a major influence on American Orthodoxy is a fairly recent phenomenon, due in large part to his having many descendants who translated his work into English and got them published. The other side to this, I would point out, that in terms of looking for books on Jewish thought that were sophisticated enough to pass muster with an intelligent teenager and which took an engagement with an outside world as a given I did not have much in the way of alternative options but for Hirsch. So this millennial American Orthodox teenager found himself in a situation in which the only Orthodox Judaism he could relate to was from nineteenth-century Germany. This is not a critic of Hirsch. He was a great thinker and writer. I am sure if I would be able to read him in German I would appreciate him all the more. That being said one has to ask why I was never given any serious twentieth-century Jewish literature to relate to. (The closest thing I could think of is Herman Wouk's This is My God
As for me, I must admit that there was something particularly dangerous in Hirsch in that, considering my Asperger mental framework, I was not intuitively aware that I was not operating in nineteenth-century Germany and that I should not be trying to be a nineteenth-century German. So I had to push forward on my own to realize that I needed to face the reality of the twenty-first century and its unique issues; all this without the help of a useful Modern Orthodox literature. More recently I have begun reading the books of R. Jonathan Sacks and at least he is a step in the right direction. But until Modern Orthodoxy builds its own literature, it will remain caught between feeding off of Haredi and secular sources, while trying to create some personal dialectic whole between the two, and reaching back to some past thinker and trying to make him relevant for the present.
(Before readers bring up the examples of R. Joseph Soloveitchik and R. Abraham Isaac Kook, let me point out that I have been writing about my own personal experience as a teenager trying to mature into an intellectually serious Orthodox adult. Rav Soloveitchik and Rav Kook were not major influences on me at that point in my life. Furthermore, neither of these thinkers set out a coherent weltanschauung like Hirsch's Horeb
