Petter Holme @pholme.bsky.social · 27/06/2026Maybe that's what it is. The mind taps into the same circuitry we need for language processing to do other stuff, thereby conserving resources. But ultimately, my feeling is that such an analogy can't add much to our understanding of the mind, unless it's really a 121 mapping, which it likely isn't. 110
Petter Holme @pholme.bsky.social · 27/06/2026AFAIK at least some theories involving "mentalese" is about thought processes without a linguistic input or output . . these would then still involve an intermediate stage of language-like information processing 210
Petter Holme @pholme.bsky.social · 25/06/2026TLDR Of course, squares (chordless 4-cycles) often feature when there are multiple shortest paths—if a shortest path follows two edges of a square, then there is a shortest path following the remaining two edges—but, we argue, non-square contributions are negligible for most practical purposes. 011
