You're welcome. When people come up with unified theories, if you peel beneath them a tiny bit, you can find that they're actually lifting their metaphors off from other sources, and that THEY TOO, lifted their metaphors off of other sources. For example, narrative psychology? Bases human psychology on novels. Einstein's conceptualizations of time? A mathematized metaphor based upon the way movies are put together, the cameramen's placement. The illusionary nature of movies became the illusionary nature of Time. In short, Einstein is talking about movies.
