  What sort of entity is pleasure or pain? Candidates include: state, state of affairs, thing, event and property. Second, is it a first-order entity or a higher-order entity? For example, is your pain your toothache, its naggingness, or both? When you enjoy the cityscape below your viewpoint, is your pleasure your view, your enjoyment of it, the pleasurableness of your enjoyment of it, or all three? And so on. Third, does pleasure essentially have a ‘feel’ or phenomenology, a ‘something it is like’ (Nagel 1974). Fourth, does it essentially have directedness or ‘aboutness’ or intentionality? These issues about the nature of pleasure and displeasure are discussed below (see also the entry for  pleasure)  as they bear on the nature and merits of various forms of hedonism.
