Recall that abstractions are functions of low-level systems, which returns a high-level summary of said low-level system (What is an abstraction?).
This subclaim expands on the set of information in the claim Most cognitive systems learn subsets of the same abstractions by saying that natural abstractions are functions of redundantly encoded information. Namely, it says that there is a small set of information that every cognitive system learns. This information is redundantly encoded – thus, it is observable at multiple places in the observed system.
