 Moreover, a functional account of value has the theoretical advantages of being able to account for parallels between values, value interchangeability, and transvaluation. It is perhaps in taking a functional view of values and their associated imperatives where Locke's theory of value is most pragmatic. A functional view of values emphasizes the fact that values are an essential feature of our lived-experiences. At its most basic level value functionality aims to provide a way of understanding how particular values operate as coordinating mechanisms for individual and collective action. Some values have a specific social role; a societal aim or goal that they have been modified and adapted over time to help achieve or maintain. Such values are often codified in the customs and traditions of a culture and can sometimes remain ritualized long after their functional role is obsolete. The importance and usefulness of a functional view of values in Locke's social and political philosophy is further explored in  section 3.2  below.
