CORE DEFINITION

All meaningful propositions can only be divided into two categories: 1. Relations of ideas (logic/mathematics, necessarily true but no new information); 2. Matters of fact (empirical/science, new information but not necessarily true). If a book contains neither logical reasoning nor empirical facts, then "commit it to the flames, for it can contain nothing but sophistry and illusion." Scaffolding role: Classification and cleansing of knowledge. Use this standard to examine statements: Is it logical deduction (reasoning)? Or empirical fact (evidence)? If neither (such as pure emotional catharsis, metaphysical empty talk), then it has no cognitive value.

Meaningful propositions are only of two types: relations of ideas (logic/mathematics, necessarily true but no new information) and matters of fact (empirical/science, new information but not necessarily true). What is neither logical nor empirical (emotional catharsis, metaphysical empty talk) has no cognitive value and should be discarded.
