This article reviews two important recent contributions to the theory of morphology, which take significantly different approaches to the subject. Both are centrally concerned with questions of morphotactics. Rice argues that morpheme order in Athapaskan is largely the consequence of universal principles of semantic scope (coded as syntactic structure). Stump argues for a conception of inflection based on the paradigm. There is virtually no overlap between the two books, yet each raises questions that are of great significance for the other. In this review I briefly evaluate each book and then sketch the possibility of a synthesis.
