Evaluating Explanations - Adequacy:

An explanation should be informative. Its purpose, after all, is to make the explanandum intelligible, to increase our understanding of it. At a minimum, this means it should not be circular.

An explanation should get to the bottom of things. No matter what pattern we employ, an explanation is informative to the extent that it identifies the fundamental cause or reason for the explanandum.

Logical strength | Completeness | Informativeness
