When we encounter new details of our world we fill in more of the spaces. When we discover details that don't seem to fit with our view of the world, we have a kind of "crisis of faith," even if our worldview is not especially religious. We're forced to redraw our "map" a bit.

If Darwinism is true, then there is no purpose or meaning to life, there is no morality, there's no qualitative difference between humans and animals, there's no life after death, and there's no purpose to human history. Now, are you trying to tell me that it doesn't really matter if people believe we evolved or not?

Cursed is everyone who hangs on a tree.

So let's set the record straight. Faith is not the opposite of reason. The opposite of faith is unbelief. And reason is not the opposite of faith. The opposite of reason is irrationality. Do some Christians have irrational faith? Sure. Do some skeptics have unreasonable unbelief? You bet. It works both ways.

Every worldview has its ambiguities - debatable elements that people simply will not see to eye on. There's nothing wrong with that as long as the disagreement is principled and dignified. I actually think that arguments - as opposed to quarrels - are good things because they're the best way to figure out what's true. Share your reasons, listen carefully to each other, be nice, and may the best idea win.

A worldview is simply someone's relatively organized understanding of what the world is actually like.
