Ok, I get what you mean by that term then.
Stepping back to the original question, I'm trying to muddle my way through it, as it seems to lead into a very deep debate, but I think that doubt isn't so much something as it is the absence of something. It's not a 'X'--it's a 'Not-X.' Kind of like cold isn't actually a something, but cold is merely the absence of heat.
In the same way, doubt is the absence of faith to a varying degree. And so I think we should treat it similarly to faith in that doubt isn't good or bad per se, but that it all depends on what we put our faith in. In a sinful world with many false worldviews, we need doubt because we can't put our faith in everything.
And like anything else, you more appreciate things once you've lost them. If you spent the past five years in the desert where every day you were hunting for water, you'd have a much greater appreciation for living in a modern house with sinks where you can get water whenever you want.
And so I think competing worldviews and doubt make faith and Christianity more important to us when we see what life without faith in God is like.Anyways, I'm not sure if I completely answered your question, but there's my thoughts on this issue.
