Is the Brain a Computer?

I think you run into circular dependence if you exhaustively try to account for brain function by information processing. Even Claude Shannon’s definition of information depends on a «mind/perspective» defining a range of possible states. The world devoid of any perspective would have infinite states and systems depending on how you «view the world». An example I have previously given is the flickering flags computation in the tv show (books) The Three-Body Problem. This computation depends on a mind defining states and logical relations.
