I said in the comment above that "knowledge" is represented as a structure of specialized areas of the brain - stored procedures, if you wish, but the system needs to be "trained" by the spoken (or signed) language from the shared environment. The "machinery" probably has notions of a thing, a process, and an attribute, because it reflects characteristics of shared physical environment and every human language has nouns, verbs and adjectives. There are also notions of time and space, due to serialized input of sense organs and self-centered nature of our perception. Evolved, highly-specialized machinery of the brain's specialized areas reflects major characteristics of the shared environment available to it through the sense organs. There is nothing more than that. No other "knowledge".
