Swampman is a (imaginary) physical duplicate of Donald Davidson created by a freak accident by a lighning bolt hitting a swamp. Questions: do swampman’s parts (e.g., the parts shaped like a heart, liver, brain, etc.) have functions? Does swampman have intentional states? Does he have qualia? These questions have been heavily discussed in the literature. (The original examples along these lines were discussed by Boorse, Stich, and others in the 1970s.)
It reminds me of something that I think Jerry Fodor wrote somewhere: “Intuition mongering strikes me as vulgar”.
