Constructive Logic

 

a logic developed in conformity with the principles of the constructive school, distinguished by constructiveness (possibility of effective construction) of objects whose existence is affirmed in statements (propositions).

Our setting is Bishop's constructive mathematics ([3], [4], [5], [6], [8] and [15]), mathematics developed with Constructive logic (or Intuitionistic logic) - logic without the Law of Excluded Middle P [disjunction][logical not]P.
A recent articulation of this view has been developed in terms of quantification over different cases: classical logic emerges from consistent and complete cases, constructive logic from consistent and incomplete cases, and paraconsistent logic from inconsistent and complete cases.
Constructive logic accepts the truth of every integer is either even or odd, but only because we have an effective means of determining which alternative holds for any integer.

It excludes, for example, systems of constructive logic in which proofs are interpreted as programs, and it excludes uses of logic in which computation is construed model-theoretically as evaluating a formula in an interpretation.
While developing in greater detail his own version of antirealism that respects those two constraints, Tennant combines the knowability requirement with the claim that truth need not be bivalent, which in turn leads him to replace classical logic based on bivalence by a nonclassical constructive logic, namely, intuitionistic relevant logic.
