ABSTRACT

I focus on the familiar idea that if two options are on a par, then, though not rankable in relation to one another, the options are in the same neighborhood in terms of their overall value (i.e., in terms of how valuable they are overall) relative to what matters in the situation. Given this idea, which captures the key features of the notion of parity that concerns me here, it is natural to conclude that options that are on a par must be close in value and so imprecisely equally good. But this need not be so. Building on the understanding of imprecise equality that I develop here and, in some examples, and ideas in some of my prior work, I explore the possibility that there can be cases of parity (wherein the options are not rankable in relation to one another but are in the same neighborhood) that are not cases of imprecise equality.
