In the world of apologetics, there are few arguments more famous than C.S. Lewis‘ trilemma, which is found in his most popular apologetic work, Mere Christianity. Even classic arguments like Anselm’s famous ontological argument for the “being greater than which nothing can be conceived†and Pascal’s wager, while still part of the discussion of apologetics, have not in recent years been as popular, or reviled, as Lewis’ trilemma. It even spawned a book (Josh McDowell’s More Than a Carpenter) and a song (Dana Key’s “Liar, Lunatic or Lord†from the album, Part of the Mystery). [On a side note, both of these are guilty in my mind of the problems which Alister McGrath points to when you make the trilemma try to function as a proof of divinity. I think McDowell in particular creates misunderstanding regarding the trilemma, which should be critiqued. However, since this piece is about Lewis’ trilemma, and not McDowell’s misapplication, I will only state here that I do not think McDowell is an example of how to understand Lewis.] However, just because an argument is famous, does not mean that is valid as an argument or even that it provides some kind of compelling existential draw. As an example of what I mean, I would look to Anselm’s ontological argument. While I recognize it has flaws as an argument, it continues to fascinate me. I find something existentially compelling to it, and how it has been used (and abused) through history. Conversely, I have never found Pascal’s wager that interesting, though many do. Lewis’ trilemma is one of those arguments which seems to have flaws built into it, but still many people are drawn to it. But do those who critique the argument really land on what Lewis is doing in the trilemma? I do not believe that they do. To demonstrate this, we will consider the argument itself, look at the problems which people have with it and see if these problems really fit with what Lewis wants to do in the trilemma.
