Formal Logic Inference: Preserving Truth

From the examples of boolean logic and predicate logic we can see that formal logic is operating with a set of expressions assumed to be true and then offers some rules how one can derive from this set of assumed true expressions some concrete expressions. The whole inference mechanism works strictly ‘conservative’ in the sense that it is not possible to ‘create’ by logical inference ‘something new’. Formal logical inference is preserving the truth.
