propositional logic
     
         (or "propositional calculus") A system of {symbolic
        logic} using symbols to stand for whole {propositions} and
        {logical connectives}.  Propositional logic only considers
        whether a proposition is true or false.  In contrast to
        {predicate logic}, it does not consider the internal structure
        of propositions.
