TITLE: "Inception" and the Simulation Argument AUTHOR: Eugene Wallingford DATE: September 06, 2016 2:44 PM DESC: ----- BODY:
If Carroll's deconstruction of the simulation argument is right, then the more trouble we have explaining consciousness, the more that should push us to believe we're in a ground-level simulation. There's probably a higher-level version of physics in which consciousness makes sense. Our own consciousness is probably being run in a world that operates on that higher-level law. And we're stuck in a low-resolution world whose physics doesn't allow consciousness -- because if we weren't, we'd just keep recursing further until we were.
-- Scott Alexander, The View From Ground Level
two characters from the film 'Inception' walking in a dream world where space folds back on itself
In the latest installment of "You Haven't Seen That Yet?", I watched the film Inception yesterday. There was only one person watching, but still the film gets two hearty thumbs-up. All those Ellen Pages waking up, one after the other... Over the last few years, I've heard many references to the idea from physics that we are living in a simulation, that our universe is a simulation created by beings in another universe. It seems that some physicists think and talk about this a lot, which seems odd to me. Empiricism can't help us much to unravel the problem; arguments pro and con come down to the sort of logical arguments favored by mathematicians and philosophers, abstracted away from observation of the physical world. It's a fun little puzzle, though. The computer science questions are pretty interesting, too. Ideas like this are old hat to those of us who read a lot of science fiction growing up, in particular Philip K. Dick. Dick's stories were often predicated on suspending some fundamental attribute of reality, or our perception of it, and seeing what happened to our lives and experiences. Now that I have seen Memento (a long-time favorite of mine) and Inception, I'm pretty happy. What Philip K. Dick was with the written word to kids of my generation, Christopher Nolan is on film to a younger generation. I'm glad I've been able to experience both. ~~~~ The photo above comes from Matt Goldberg's review of Inception. It shows Arthur, the character played by Joseph Gordon-Levitt, battling with a "projection" in three-dimensional space that folds back on itself. Such folding is possible in dream worlds and is an important element in designing dreams that enable all the cool mind games that are central to the film. -----
