More about language, apparently, not all languages have that "ideas within ideas within ideas" property you were talking about. The Pirahã language of an indigenous people in Brazil is the counter example. This New Yorker article talks about it and the fascinating effects it had on the field of linguistics. Before its discovery most linguists, Led by Chomsky, believed having recursion in our grammars set humans apart from all other animals. Pirahã showed this might not be the case.
