The Löwenheim-Skolem Theorem and the Compactness Theoremoperties of semantic notions to syntactic ones. In Section 2 we make use of this connection in the other direction and get several important results for ⊢ and Sat. Together with the theorems in Section 1 they will provide us with a deeper insight into the expressive power of first-order languages.

The Scope of First-Order Logicorresponds to the intuitive concept of mathematical proof. The Completeness Theorem then shows that every proposition which is mathematically provable from a system of axioms (and thus follows from it) can also be obtained by means of a formal proof, provided the proposition and the system of axioms admit a first-order formulation.

Syntactic Interpretations and Normal Formsactic interpretation will turn out to be a central concept for our considerations. In the section about normal forms we show that, for different syntactic properties, one can find for each formula a logically equivalent one which has this property, e.g., one which has syntactically an especially simple form.
