 Since abilities are, as noted in Section 1.1, a kind of power, one natural idea is to analyze abilities in terms of some other kind of power. This appeal may proceed in different ways. One is by appealing to dispositions, and by analyzing abilities in terms of this purportedly better-understood kind of power. Another is by departing more radically from the standard ontology of recent metaphysics, and analyzing ability in terms of some new and distinctive variety of power. We will consider these approaches in turn in Sections 5.1 and 5.2. Finally, in Section 5.3, we will turn to miscellaneous alternative approaches to ability, which reject the conditional and modal analyses, but which do not purport to analyze abilities in terms of powers either.
