The proof can be extended to arbitrary FO-sentences by forming structures that are obtained from Herbrand structures via taking the equivalence classes of terms according to the equalities between them in some structure satisfying the FO ...

LINEAR LOGIC AS A FRAMEWORK FOR SPECIFYING SEQUENT
... where ∆ is the multiset union of ∆1 and ∆2 , and A is the multiset union of A1 and A2 . In other words, those subgoals immediately to the left of an ⇒ are attempted with empty bounded contexts: the bounded contexts, here ∆ and A, are divided up to be used to prove those goals immediately to the left ...

LOGICAL CONSEQUENCE AS TRUTH-PRESERVATION STEPHEN READ Abstract
... What these proofs show is that, if we suppose that 3 represents implication (real implication), then an impossible proposition implies any proposition, and if ⊃ represents implication, even a false proposition implies any other. Neither proof shows that these are sound principles about implication. ...

The magic of how deductive reasoning works is that we can judge whether the reasoning is valid independent of whether we know tha ...

Constructing Cut Free Sequent Systems With Context Restrictions
... unlabelled sequent systems that are amenable to saturation under cuts between rules. In case the resulting rules fulfil our criteria for cut elimination and are also tractable they give rise to a generic Exptime decision algorithm for the logic. Our main contributions are the following: we formalise ...

Intuitionistic Logic

Then ¬A ∨ B does not hold constructively, but on the interpretation following here, the implicat ...

Inquiry
An inquiry is any process that has the aim of augmenting knowledge, resolving doubt, or solving a problem. A theory of inquiry is an account of the various types of inquiry and a treatment of the ways that each type of inquiry achieves its aim.
