The puzzle of cross‐modal shape experience is the puzzle of reconciling the apparent differences between our visual and haptic experiences of shape with their apparent similarities. This paper ...proposes that we can resolve the cross‐modal puzzle by reflecting on another puzzle. The puzzle of perspectival character challenges us to reconcile the variability of shape experience through shifts in perspective with its constancy. An attractive approach to the latter puzzle holds that shape experience is complex, involving both perspectival aspects and constant aspects. I argue here that parallel distinctions between perspectival and constant aspects of shape experience arise in sight and touch, and that perspectival aspects are modality‐specific while at least some constant aspects are constitutively multisensory. I then address a powerful challenge to the idea that aspects of spatial phenomenology are shared cross‐modally.

We investigate a new sort of puzzle of self-reference, in which the puzzler is asked to find the cardinality of a set defined in terms of its own cardinality. We discover which sets are the unique ...solution to such puzzles and see how puzzles for such sets can be made arbitrarily complex. Then we compare our new cardinality puzzles to the classic puzzles of knights and knaves.
