A branch of logic that deals with the → truth values
of logical statements (→ sentences,
→ propositions) and uses
→ logical connectives to build more complex
→ expressions. The distinctive feature of propositional logic
is that it does not deal with logical relationships and properties that involve the
parts of a statement smaller than the simple statements making it up. The propositions
are evaluated as → true or → false.
A more expressive system is provided by the → first-order logic.
