Faith over Logic is what you use to draw the masses. Most people find thought and any kind of calculation a burden. I used to have a co-worker who would sign papers without reading, it was too much trouble to read. Same kind of thing. There are major holes in your major religions. Stuff that doesn't make sense. But no one thinks about them, that's how they find purpose in life, that's how they hold on to their hope. That's how they make peace with death. Except that when you don't think, when you live in denial of the hard questions and comes up death looks you in the eye, you can't hide anymore, and you must think (if have time) because now eternity rests on the things you've been hiding from.

There is a lot of stuff in the Davinci Code that I knew before starting the book. The fact that the Roman Catholic Holidays are just thin masks for paganism, for instance. Nobody is going to look at the holes in their religion while life and it's problems can distract them from it. It's like preaching to rocks.

The Davinci Code really is a badly written book. A good story and well told, but I can only think that that's due to the hard work of a good editor. The language is clichéd and basic, characters are shallow, and as for everything except for the symbolism and a few facts about Opus Dei, it's all been done before.
