The Foundations of Econometrics --- Are There Any?

The conclusions of a logically consistent economic theory which strictly adheres to Aristotle's axioms of logic are factually true if its sufficient conditions are all factually true. Alternatively, if a conclusion of such a theory is false, then at least one of its assumptions is false. Unfortunately, the factual truth of sufficient conditions cannot be established because the problem of induction is impossible to solve. It is also true that the falsity of a conclusion cannot be established in the presence of uncertainty. While the philosophy of instrumentalism applied to sufficient and logically consistent explanations may provide useful solutions to immediate practical problems, the principles of simplicity, parsimony and profligacy--all of them requiring conditional deductive arguments--are useless as criteria for model choice
