Abstract

This spare book amply maintains the distinction of the Bradford Book series. In chapter 1 Cummins argues that the familiar deductive-nomological notion of scientific explanation only covers transitional theories and fails to give an account of explanation through property or system analysis that is pervasive in both the physical and psychological sciences. This inadequacy of the D-N view is supposed particularly injurious in the unrobust and infant science of psychology. Explanation through analysis ranges from decidedly morphological to the decidedly systemic, and from the interpretive to the descriptive. Explanation through analysis is typically an interactive two step: one gives a revealingly helpful component-function or programmatic analysis and one hopes to find an explanatory instantiation of this analysis. Psychological explanation is importantly systemic and its most challenging problem is that of finding isomorphisms between interpretive instantiations and descriptive instantiations-the hope for two-stepping isomorphisms in human psychological explanation is bio-logical, the sorts of structures that genes can determine being the likely candidates for our psychological capacities.
