A Dormitive Virtue?
Chapter 9 considers objections to the account of persistence offered in chapter 8. The bulk of the chapter is taken up with the question of explanatory significance: according to the objection from dormitive virtues, powers cannot properly be said to be explanatory. In response, it is argued that causal explanations must reflect the ontological facts, and therefore that explanations are ontology-relative. Consequently, on the assumption that the correct ontology is one that countenances fundamental causal powers, powers come out as explanatory. Powers-based explanations—in the right contexts—are thus vindicated. Further objections regarding the possibility of random creation and gunk are considered.
