Various sources in the literature claim that the deduction theorem does not hold for normal modal or epistemic logic, whereas others present versions of the deduction theorem for several normal modal systems. It is shown here that the appar- ent problem arises from an objectionable notion of derivability from assumptions in an axiomatic system.

[10] To get the rule of necessitation right, there are six ways of defining deductive consequence deduction theorem (plural deduction theorems) (logic) A procedure for "discharging" assumptions from an inference, causing them to become antecedents of the conclusion; or vice versa. Symbolically, the conversion of an inference of the form to an inference of the form Define deduction theorem. deduction theorem synonyms, deduction theorem pronunciation, deduction theorem translation, Theorem 5.8 (Soundness).

### Theorem 5.8 (Soundness). The systems FOL C are sound. Proof. The proof is similar to the proof of soundness for SL (Theorem 2.4). Let D be a deduction in FOL C of a formula Afrom a set of sentences. We shall show that, for every line Cof D, j= C. Applying this to the last line of D, this will give us that j= A. Assume that what we wish to show

Deduction theorems exist for both propositional logic and first-order logic. The deduction theorem is an important tool in Hilbert-style deduction systems because it permits one to write more comprehensible and usually much shorter proofs than would be possible without it. In mathematical logic, the deduction theorem is a metatheorem of first-order logic. It is a formalization of the common proof technique in which an implication A → B is proved by assuming A and then deriving B from this assumption conjoined with known results.

### In mathematical logic, a deduction theorem is a metatheorem that justifies doing conditional proofs — to prove an implication A → B, assume A as an hypothesis and then proceed to derive B — in systems that do not have an explicit inference rule for this. Deduction theorems exist for both propositional logic and first-order logic.

The Deduction Theorem In logic (as well as in mathematics), we deduce a proposition B on the assumption of some other proposition A and then conclude that the implication "If A then B " is true. This line of argument is justified for the formal axiomatic system by the following well-known theorem. The deduction theorem says that: if Q can be logically inferred from P, then ‘If P then Q’ can be proved as a theorem in the logical system in question. The term deduction theorem is due to David Hilbert (Hilbert and Bernays 34–39).
