Semantics of logic

In formal semantics, truth-value semantics is an alternative to Tarskian semantics.
Truth-value semantics (also commonly referred to as substitutional quantification) was advocated by Ruth Barcan Marcus for modal logics in the early 1960s and later championed by Dunn, Belnap, and Leblanc for standard first-order logic. James Garson has given some results in the areas of adequacy for intensional logics outfitted with such a semantics. The truth conditions for quantified formulas are given purely in terms of truth with no appeal to domains whatsoever (and hence its name truth-value semantics).

For example, one can use quasi-quotation to illustrate an instance of substitutional quantification, like the following:

Universal quantification

The idea of these semantics is that universal (existential) quantifier may be read as a conjunction (disjunction) of formulas in which constants replace the variables in the scope of the quantifier.

First-order logic

predicate logicfirst-orderpredicate calculus
The main difference between truth-value semantics and the standard semantics for predicate logic is that there are no domains for truth-value semantics.

Atomic formula

Whereas in standard semantics atomic formulas like Pb or Rca are true if and only if (the referent of) b is a member of the extension of the predicate P, respectively, if and only if the pair (c,a) is a member of the extension of R, in truth-value semantics the truth-values of atomic formulas are basic.

Logical consequence

Clearly the formula ∀xF(x) is a logical consequence of the set, but it is not a consequence of any finite subset of it (and hence it is not deducible from it).
