This is an ongoing theme Tarkovsky's interested in—think the scientists around Solaris. I think is something the anti-academic vibe of this forum gets right—the way many scholarly explanations are non-explanations, "semantic stop signs" I've heard them called—plugs on curiosity or inquiry that put on the image of understanding.
