David Hume gave the distinction its classical formulation in his dictum that it is impossible to derive an "ought" from an "is".
As Hume and Kant pointed out, however, it is fallacious to derive a proposition with existential import from a tautology, and it is now generally agreed that, from a tautology alone, it is impossible to derive any significant proposition.
Criteria for the choice of axioms include: (1) consistency it should be impossible to derive as theorems both a statement and its negation; (2) plausibility axioms should be in accord with intuitive beliefs about sets; and (3) richness desirable results of Cantorian set theory can be derived as theorems.
By "consistent" Hilbert meant that it should be impossible to derive both a statement and its negation; by "complete," that every properly written statement should be such that either it or its negation was derivable from the axioms; by "decidable," that one should have an algorithm that determines of any given statement whether it or its negation is provable.
