Wikipedia Overview
Popper's three worlds is a theory developed by Karl Popper in the late 1960s. It involves three interacting worlds. World 1 is the material realm, World 2 is the mental realm, and World 3 is the cultural realm. Popper's goal was to defend his notion of objective knowledge against the rising notion that knowledge is a belief that must be justified and true. This theory supported his old view that theories need not be verified by induction. In his approach, the methodological rules as well as the logical content of science belong to World 3. The theory is evolutionary. Popper was a strong advocate of a theory of emergence in which each world is not predetermined by previous ones.
