Functional Conception of Quantification Theory

All,
Up till now quantification theory has been based on the assumption of
individual variables ranging over universal collections of perfectly
determinate elements. The mere act of writing quantified formulas
like (∀x∈X)f(x) and (∃x∈X)f(x) involves a subscription to such notions,
as shown by the membership relations invoked in their indices.
As we reflect more critically on the conventional assumptions in the
light of pragmatic and constructive principles, however, they begin
to appear as problematic hypotheses whose warrants are not beyond
question, as projects of exhaustive determination overreaching
the powers of finite information and control to manage.
Thus it is worth considering how the scene of quantification theory
might be shifted nearer to familiar ground, toward the predicates
themselves which represent our continuing acquaintance with phenomena.
Regards,
Jon
