Pinky and the Brain, and unit economy
Ironically, I came across this cartoon clip while preparing some teaching materials on neuroanatomy. I think it quite effectively illustrates the cognitive need of unit economy, as well as the need for a word (or name) to adequately "differentiate [a concept] from all other concretes and all other concepts" (ITOE, pg. 10). Enjoy.
