The validity of statistical induction

The validity of statistical induction In my judgment, the practical usefulness of those modes of inference, here termed Universal and Statistical Induction, on the validity of which the boasted knowledge of modern science depends, can only exist—and I do not now pause to inquire again whether such an argument must be circular—if the universe of phenomena does in fact present those peculiar characteristics of atomism and limited variety which appear more and...

Why economic models do not give us explanations

Why economic models do not give us explanations Economic models frequently invoke … entities that do not exist, such as perfectly rational agents, perfectly inelastic demand functions, and so on. As economists often defensively point out, other sciences too invoke non-existent entities, such as the frictionless planes of high-school physics. But there is a crucial difference: the false-ontology models of physics and other sciences are empirically...
