  Monism about pleasure is the thesis that there is just one basic kind of mental state or property that is pleasure. Phenomenal monism holds that there is just one basic kind pleasure feeling or tone, while intentional monism claims there is just one basic kind of pleasure intentional state or property. The disunity objection to monism is based on the claim that there is no unified or common element in all instances of pleasure (e.g., Sidgwick: 127, Alston: 344, Brandt: 35–42, Parfit: 493, Griffin: 8, Sprigge: ch. 5). With few exceptions if any, such objections have to date targeted phenomenal monism. But both the objection and the possible replies to it are under-explored in the different context of intentional monism. The standard phenomenal monist reply is to insist that there is just one basic kind of pleasure and that this is a matter of there being a common element in pleasure's feeling, felt tone, or phenomenology, or in ‘what it is like’ to have pleasure (e.g., Moore: 12–13, Broad: 229, Sumner: 87–91). Broad, for example, wrote that the common phenomenal character of pleasure is something “we cannot define but are perfectly acquainted with” (Broad: 229). Alternatively, if some definition is to be attempted, one thought is that the common phenomenal character of all pleasure is just its felt pleasantness. A different claim is that there is a common feel-good character or felt positivity in all pleasure. This claim is not clear, but can be spelt out in at least the following three different ways: that there is such a property as felt positivity and that all instances of pleasure have it; that all pleasure consists partly in feeling the existence of goodness or value; or that all pleasure has goodness or value as an intentional object, and this is so whether or not goodness or value exists.
