First order logic predicate

WebWe use a recursion scheme for the formulas of first-order predicate logic. These are like propositional logic formulas, except: An atomic proposition is a predicate: a string constant accompanied by a list of terms. Subformulas may be quantified by a universal (Forall) or existential (Exists) quantifier.
