  This last point deserves much more discussion than it has previously received. It has generally been assumed that if there is a relation between identity and our practical concerns, it is some sort of univocal relation, running from a single (correct) theory of personal identity to all of our person-related practical concerns (whether it's a grounding relation, an explanatory relation, a revealed relation, or something else). But why should we think this is the case?  Instead, why not think that some practical concerns are grounded by one relation and other concerns are grounded by another?
