The short answer is that the paradox or dichotomy between the 3's and 4's (taken to their extremes) is actually like mixing oil and vinegar. The 3's point of view is the experiential (audience) point of view. The 4's point of view is the logistical (author) point of view. The StoryGuide with it's Signposts and Journeys is somewhat of a cheat, kind of like mixing the oil and vinegar. The signposts are 4's and the journeys are 3's. If you mix them up enough they SEEM to blend to create a smooth homogenous consistency, but let them sit still for a moment and they appear to separate back into oil and vinegar, 3's and 4's.
