Abstract
Some recent theories in theoretical physics are not subject to epistemic evaluation by empiricist standards of evidential warrant. The advantage of these theories is not pragmatic but explanationist; they fail to yield testable consequences that distinguish them from earlier theories. But this is essentially a technological limitation, rather than a theoretical defect. There is an explanation, itself confirmed by empiricist standards, of the unconfirmability of these theories. This paper considers what epistemic stance is proper in this situation, and explores the prospects for justifiable change to an explanationist methodology capable of warranting theories that transcend the range of our experience.
