Science has taught us, against all intuition, that apparently solid things like crystals and rocks are really almost entirely composed of empty space. And the familiar illustration is the nucleus of an atom is a fly in the middle of a sports stadium, and the next atom is in the next sports stadium.

Most of what we strive for in our modern life uses the apparatus of goal seeking that was originally set up to seek goals in the state of nature.

We think we know that chimpanzees are higher animals and earthworms are lower, we think we've always known what that means, and we think evolution makes it even clearer. But it doesn't. It is by no means clear that it means anything at all. Or if it means anything, it means so many different things to be misleading, even pernicious.

Evolution is just a theory? Well, so is gravity and I don't see you jumping out of buildings.

People who do not know the Bible well have been gulled into thinking it is a good guide to morality. This mistaken view may have motivated the "millionaire Conservative party donors".

The surest way to disabuse yourself of this pernicious falsehood is to read the Bible itself.
