Here’s a fun and pointless way one could rescue the homunculus model: There’s an infinite regress of homunculi, each of which sees a reconstructed image. As you pass up the chain of homunculi, the shadow gets increasingly attenuated, approaching but never reaching complete invisibility. Then we identify “you” with a suitable limit of the homunculi, and what you see is the entire sequence of images under some equivalence relation which “forgets” how similar A and B were early in the sequence, but “remembers” the presence of the shadow.
