This morning in church the pastor quoted C.S. Lewis’ well known “lunatic, liar, or lord,” trilemma during his sermon. I didn’t sleep much last night, so I was primed to chase a rabbit, and this was it.

Immediately this argument, which I had accepted wholeheartedly as a freshman in college and held in the back of my mind ever since, struck me as problematic. It became clear that the problem for me was the assertion that a person isn’t “morally reliable” if they are deceived or deceptive. In either case, it is not only acceptable, but perfectly logical to accept moral teaching from a lunatic or a liar.

In the Modern era morality is not the stable and absolute entity that it is in earlier times, and in the postmodern era it is no longer even broadly coherent. It is understood as a social and cultural construct, and in the pluralistic societies of the Western world, it is also understood as an individual construct. We can, as individuals or societies, develop our own personal or local moral codes through our own invention and through collecting the parts of existing codes that we accept as valid.

Lewis’ argument rests on the belief that if we accept some of a person’s teaching, we have to accept all of it. But people are unreliable—at one moment they are honest, in the next deceptive. So we test and examine each part of their teaching, take the good, and leave the bad. And even crazy people and conmen speak the truth sometimes.

In the view of the non-believer, Christian teaching is no different. You look to the Bible, take what you can agree with, leave what you can’t, and put together your own package. In truth, you could accept Jesus as a “good moral teacher”, and you would be making a logical decision. You’d be wrong…but not illogical.

Logic won’t always lead to a single solution. It should always bring you closer to an accurate answer, but you are still likely to be forced to choose among multiple logical choices. Praise God that as the “postmodern impulse”, as George Knight calls it, grows, we will be able to focus less on logic and more on the beauty and worth of Jesus as our primary apologetic.

As I looked into other arguments against this position I found this article and this Google books scan of writings by N.T. Wright that address the subject. What I found there makes me want to get Surprised by Hope down off the shelf and finally finish reading it. Not yet though, I have some work to do…
