As I discussed in “The Prankquean’s Riddle,” one of the issues raised by the riddle — “Why do I am alook alike a poss of porterpease?” — is the enigmatic question of identity.

Some ways of glossing the riddle include “Why do I look like you?” or “Why do I look like our children?” or “Why are we a family; what makes us a family (the Porter family, a pod of peas)?”

What is a family, anyway? What am “I,” that I can resemble or be something at all?
