  Pluralism in the present setting is the thesis that there is more than one basic kind of state or property that is pleasure, that pleasure is multiply or variously or diversely realizable, or that there is a basic plurality of sufficient conditions for pleasure. The core idea is that there is a basic plurality of kinds of feel or of intentional state, each of which is a kind of pleasure (e.g., Rachels, Labukt, perhaps Rawls: 557). The unity objection to any such pluralism is that all instances of pleasure must meet some unitary sufficient condition, and that pluralism is inconsistent with this. The obvious pluralist reply is to reject this demand for unitariness. One rationale for this reply is that multiple or plural realization theses about many kinds of mental states are coherent, widely made and merit serious consideration, so the unity objector is not justified in thus seeking to rule them out at the outset of inquiry into the nature of pleasure.
