Bolzano himself identifies explicitly the form of a proposition with a set of propositions (WL I, 48, WL II, 82): The form of a proposition s with respect to a sequence i of ideas or (as an abbreviation) the iform of s is the set of all ivariants of s, provided that at least one of the ik™s is contained in

A propositional iform can therefore be defined as the iform of at least one proposition s; and a propositional form is a propositional iform with respect to at least one sequence i.

(For cases in which this proviso is not met, neither an ivariant of s nor the iform of s is defined.)

A proposition s is universally valid (or universally contravalid, respectively) with respect to a sequence i of ideas iff there is a propositional form F such that F is a propositional iform which is universally valid (or contravalid, respectively), and s is a member of F.
