Unreasonable?

Today in class, and as I was reading the blog this afternoon, I was struck by the idea of rationality that is assumed in all our discussion: Was it rational for Susan and Peter to believe Lucy when she told them her fantastic story about Narnia? Could a logical mind really believe (whether they choose to or not) in a magic land just out of sight?

Background: Last fall in Music of the Church, I read a book called Wiser Than Despair by Quentin Faulkner. It is a history of music in the church and has a large portion on the effects of the Enlightenment on the Church in general and church music in particular. In this reading, I realized that the logical/rational/scientific way of thinking that we so easily take for granted is not the way that humans have thought throughout time; it's very new in the course of history. Does this mean that all the humans before, let's say, 1700 were devoid of the tools for thinking properly? Does this mean that we have the right to look down on them as less civilized?

My question: Why are we so dead-set against belief in the supernatural or the incredible? Does something not exist simply because we cannot scientifically prove it? Perhaps, in Narnia, Lewis is asking us to question what we see as reality. Is it only what we can touch? Or could there be more, unseen but completely real, that we refuse to recognize? Does it offend our rational sensibilities to trust in what we can't see? Perhaps the reason that Peter and Susan did not believe Lucy was that they would feel silly or childish in doing so.

Because most of you are Christians, I know that you do believe there is more to this world and this life than what we can touch. There is a God who loves and lives and moves, but do we expect Him to fit into our neat, scientific view of the world? Do we fear trusting Him with all that we are because He doesn't always make logical sense to us? Remember, "He is not a tame lion."
