"Haddocks' Eyes" is a term for the name of a song sung by The White Knight from Lewis Carroll's 1871 novel Through the Looking-Glass, chapter VIII. "Haddocks' Eyes" is an example used to elaborate on the symbolic status of the concept of "name": a name as identification marker may be assigned to anything, including another name, thus introducing different levels of symbolization. It has been discussed in several works on logic and philosophy.
