The term "universal quantifier" is a misnomer. The symbol cannot exist on its own and since there is no such thing as "for some x in P," for example, then the variability assumed in quantities doesn't materialize. Just find and copy/ paste a statement, such as "not forall x there exists..."epix, please read about Universal quantification ( http://en.wikipedia.org/wiki/Universal_quantification ), before you air your view about this subject.
Objects belong to a particular set or they don't. If you define a set, you define its membership in such away that there doesn't exist at least one member that doesn't satisfy the definition of the membership. If you consider incrementing the size of the set by at least one member, you need to know if the property of such object satisfies the definition of the set. That means the subject of the possible increment either qualifies or not. So I treat A upside down as a qualifier. "Forall x in S" means that for every x that satisfies the definition of S, there exist... or whatever follows.
Tell you something: Once I stack with the general definition of a spacial point, applied it and saw sh-t. Then I redefined the point as a square whose side approaches zero. Having done so, that stuff I wanted to see showed up right before my eyes. If you parrot everything what the theoretician say, nothing gets done -- ever.
