Explicit Constructive Logic Ecl: A New Representation Of Construction And Selection Of Logical Information By An Epistemic Agent

One of the main goals of Explicit Constructive Logic (ECL) is to provide a constructive formulation of Full (Classical) Higher Order Logic LK omega that can be seen as a foundation for knowledge representation. ECL is introduced as a subsystem Z(omega) of LK omega. The first order case Z(1) and the propositional case Z(0) of ECL are examined as well. A comparison of constructivism from the point of view of ECL and of the corresponding features of Intuitionistic Logic, and Constructive Paraconsistent Logic is proposed.
