I was trying to think of a world-view which is all-encompassing, but it's pretty difficult. For example, Marxists might analyze various historical events, but would Marxism help them in personal relationships? I doubt it, but I would be interested to hear of anything different.
It starts to become very intellectual, if you are applying a world-view all the time. For example, as I am walking along the salt-marsh in Norfolk, which world-view will I apply here? From my point of view, none really. I like the view, and the migration has started early this year. Etc.
We are fragmentary beings, who construct collages of bits and bobs, which don't add together coherently. Life is a bricolage! This is a posh word for a mess.
