Abstract

A notion of an ideal sense of knowledge is introduced. A formal language for sortals with a propositional operator formally representing such a notion is then defined. The formal language will contain temporal operators as well. A formal semantics for the language is defined and on its basis three sorts of semantic validity are distinguished, which correspond to nativist and non-nativist views of concept-formation. A formal system for epistemic-radical nativism is stated. Soundness and completeness can be shown for the system. The soundness and completeness proofs for non-nativist as well as partial nativist validity are left as open problems.
