General Remarks

The formal language symbols and well defined set of formulas i.e. established syntax do not directly carry with them any logical value.

We assign a logical value to syntactically defined formulas of a given language in a separate step.

This next step is called a semantics of the given language.

We will see that a given language can have different semantics and the different semantics will define different logics.
