What is Prudential values?

Answer 1

Prudential value also known as Well-being, is named such to be distinguished from, for example, aesthetic value or moral value. What marks it out is the notion of 'good for'. The serenity of a Vermeer painting, for example, is a kind of goodness, but it is not 'good for' the painting. It may be good for us to contemplate such serenity, but contemplating serenity is not the same as the serenity itself. Likewise, my giving money to a development charity may have moral value, that is, be morally good. And the effects of my donation may be good for others. But it remains an open question whether my being morally good is good for me; and, if it is, its being good for me is still conceptually distinct from its being morally good.
