C.S. Lewis famously presents a Lord-Liar-Lunatic trilemma in Mere Christianity. I've long been familiar with some of the responses to that argument, and I've given my own version of it that deals with at least some of those problems (among the other things I deal with in that piece). What I didn't know is that Lewis himself had a more sophisticated development of the argument that includes some responses to the most common reasons I've heard from people who think his argument is fallacious. It's even in God in the Dock, which I have on my shelf but never got around to looking at very carefully due to being thoroughly unimpressed with his arguments in Mere Christianity and one view he made clear at the end of The Last Battle.
Well, a friend of mine was looking for his essay "What Are We to Make of Jesus?", and I found it for her, figuring it might be worth reading. I was actually fairly impressed. Check it out.
By tying the argument that Jesus claimed divinity to a wider range of sayings and actions in the gospels (though not wide enough, given what he could do), he makes a stronger argument that Jesus really did claim to be God, which some people have tried to undermine to get out of the argument. He also makes clearer what issue is at stake -- if Jesus really said these things and meant them, and it wasn't true, he was nuts, but that doesn't seem very likely given how insightful his moral teachings were about the human condition. That means either he made it up, which is also unlikely for someone with such great moral sensitivity, or he had good reasons for thinking it's true, which is hard to fathom unless it is true. I don't think all those steps were filled in in the Mere Christianity version of the argument.
