First, we show that the natural simple type system for SKInT, seen as a natural deduction system, is not exactly a proof system for intuitionistic logic, but for a very close fragment of the modal

In first order logic this can be written as \(\forall n (\mathit{prime}(n) \to n > 1)\). The reason is that the original statement is equivalent to the statement “for every natural number, if it is prime, then it is greater than 1”.

In particular, there are finitary proof systems complete with respect to the semantics. In first-order logic, assertions about elements of structures can be ex-pressed. First-Order Logic • Propositional logic only deals with “facts”, statements that may or may not be true of the world, e.g. “It is raining”. , one cannot have variables that stand for books or tables.

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.
