Noam Chomsky's Hierarchy of Knowledge

Noam Chomsky's Hierarchy of Knowledge categorizes the levels of human linguistic and logical understanding. It ranges from basic, empirical facts ("type 0") to complex, abstract reasoning and language structures ("type 3"). This hierarchy helps us understand how knowledge progresses—from simple observations to sophisticated theories and rules that describe and generate language and thought. Each level builds on the previous, illustrating increasing complexity in human cognition, and guiding fields like linguistics, computer science, and philosophy on how language and knowledge are structured and developed.
