For example: it is unwise to pontificate about God, unless you have at least tried to reproduce his creative power; and even then better not to say too much. Can biologists create life? The real question is not whether evolutionary biologists might be right in thinking there is no spiritual world; but rather how they can be so unobservant as not to see that all life contradicts them?
The whole point of science is that it investigates inorganic and organic matter, and leaves out of account any spiritual component which this matter may have. So of course science postulates a mechanical view of the Universe; it is the whole business of science to do just that. But when you explore the world of the spirit and imagination, you may come to a very different opinion; and unless the entire world of the spirit and imagination is an illusion, you are likely to do so, because Complexity changes the Rules.
