Well-Being and Approximation

Abstract What is the relation between what is good for you and how well you are doing? It is common and natural to think that the latter asymmetrically depends upon the former. I call this the molecular model of well-being, which holds that how well you are doing depends directly upon the presence of independently specifiable welfare goods in your life. Just about every contemporary theory of well-being embodies the form specified by the molecular model. Here I articulate and defend an alternative way to think about well-being, a way based upon the notion of approximation. According to the approximation model of well-being, how well you are doing directly instead depends upon how closely you resemble an ideal way to live. One person is doing better than another just in case the life of the first more closely approximates the ideal life. To make this case I briefly sketch a substantive theory of well-being that employs it: what I take to be Aristotle’s view of well-being, which works as a proof of concept. We see that the approximation model of well-being can explain some patterns of value better than the molecular model can.
