  One final clarification about different understandings of pluralism ought to be made. There is an ambiguity between the name for a group of values and the name for one unitary value. There are really two problems here: distinguishing between the terms that refer to groups and the terms that refer to individuals (a merely linguistic problem) and defending the view that there really is  a candidate for a unitary value (a metaphysical problem). The linguistic problem comes about because in natural language we may use a singular term as ‘shorthand’: conceptual analysis may reveal that surface grammar does not reflect the real nature of the concept. For example, we use the term ‘well-being’ as if it refers to one single thing, but it is not hard to see that it may  not. ‘Well-being’ may be a term that we use to refer to a group of things such as pleasure, health, a sense of achievement and so on. A theory that tells us that well-being is the only value may only be nominally monist. The metaphysical question is more difficult, and concerns whether there are any genuinely unitary values at all.
