Abstract

The Renaissance of Prudential Psychology Philosophical reflection on the good life in coming decades will likely owe a tremendous debt to the burgeoning science of subjective well-being and the pioneers, like Ed Diener, who brought it to fruition. While the psychological dimensions of human welfare now occupy a prominent position in the social sciences, they have gotten surprisingly little attention in the recent philosophical literature. The situation appears to be changing, however, as philosophers inspired by the empirical research begin to examine more seriously the psychology of human flourishing. This is not to say that the philosophers of any era have kept entirely silent about such matters. While the term ‘subjective well-being’ has yet to take a significant place in the philosophical lexicon, philosophers have always evinced some interest in the subjective or psychological dimensions of human welfare, and sometimes quite a lot. Philosophical work on the good life has traditionally been the province of ethical theory, which may be understood broadly to include all aspects of value theory. Ethics in this broad sense is one of three main branches of philosophical inquiry, alongside metaphysics and epistemology. Philosophers sometimes use ‘ethics’ more narrowly, as a synonym for ‘morality’ or ‘moral theory’. But ethical theorists frequently claim to be in the business of trying to answer Socrates’ question: how ought one to live? And this question ranges well beyond matters of right and wrong, dealing also with matters of well-being, flourishing, welfare, eudaimonia, or pruden- tial value. There is some dispute about the precise equivalence of these expressions, which carry differing connotations. But all seem to concern the same cluster of issues: what benefits a person, is in her interest, or makes a person’s life go best for her. Thus contemporary theories of “wellbeing” or “welfare” appear to be direct competitors to ancient theories of “eudaimonia.” It can be useful, then, to employ these expressions interchangeably, whether or not they are strictly synonymous..
