Most people do not want to think for themselves. They want a recipe for life, a bumper sticker slogan to guide them, and limited choices. They want Santa Claus and God the Hairy Thunderer. They've proven this. Science can't liberate people who cannot comprehend it, or who are kept in the dark by leaders who don't want an educated populace. I think Plato's Cave is a good way to look at this, because we haven't changed since then and never will.
