I work at the intersection of value theory and psychology. Broadly speaking, I am interested in the connection between human nature and the good life. My research ranges widely in this area but focuses mainly on the psychology of well-being and its connections with issues in ethical and political thought and policy, as well as scientific practice. I also have longstanding interests in environmental ethics, and my work on well-being is concerned partly with finding more sustainable ways to secure good lives. 

At present my chief project is a book aimed at situating happiness and well-being in the broader fabric of a good life, The Lives We Should Want. A major goal of this project is to reconcile modern attitudes about well-being with the richer ideals of the good life that can be found in the ancient tradition and others, where for instance goods like beauty and excellence might be seen as mattering in themselves, and not simply because people want or like them.

The Lives We Should Want

Under contract with Oxford University Press

Someone you know well dies, and you are asked to deliver a eulogy. Part of your task, as you see it, is to come to an accurate assessment: did she have a good life? How do you answer this question? What, in short, does it mean to have a good life: the sort of life one should want? That is the animating question of this book. The Lives We Should Want undertakes what may be the first explicit, extended defense of an account of the good life, where this notion is not simply reduced to that of well-being or the moral life. It is the second entry of a projected three-volume series that began with 2008’s The Pursuit of Unhappiness. The third, Good Societies, will extend my policy work with a focus on well-being policy.

I have released a full "beta" draft of the book as of May 9, 2023, with all materials posted here. Please cite only with permission.

Comments will be most gratefully accepted, and I would be happy to do Zoom or in-person visits with classes or reading groups. I will maintain a record of substantial changes in the published version for early readers.

 Appendix: metaethical disclaimers​


The Folk Concept of the Good Life: Neither Happiness nor Well-Being. With Markus Kneer. Evidence for a distinct concept of the good life (perhaps the one that is the subject of Lives We Should Want), and against a basic role for virtue in well-being.  

Taking the Morality Out of Happiness. With Markus Kneer. Is morality part of the ordinary concept of happiness?

Happiness and Well-Being: Is It All in Your Head? Evidence from the Folk. With Markus Kneer. An experimental investigation of the folk concepts of happiness and well-being. 

Choosing Well-Being Metrics for Policy. Argues that key metrics of well-being for policy should be, and also be validated against, consensus predictors of well-being. To illustrate, data are presented, some using a new scale devised with David Yaden, suggesting that emotional well-being measures may be at least as promising as the more popular life satisfaction instruments.

Not quite papers just yet, but Real Soon Now

In the meantime, perhaps a summary or slides will do. All have been presented in talks. 

The Limited Abilities of the Capabilities Approach. The capabilities approach is importantly distinct from, and cannot supplant, well-being policy. There's a paper I can share but it needs a major update.

Happiness, Nudges, and Freedom. Part of the problem with nudges is that they're often intrusive or manipulative, with middling benefits to show for it. The solution is to go bigger.

What matters: happiness, well-being and the good life

In a very crude nutshell: happiness = emotional well-being, or roughly the opposite of depression and anxiety. Well-being is a hybrid of hedonic and eudaimonic elements (including happiness and value-fulfillment). And a good life consists in well-being + virtue: a life well-lived, and well worth living. See also Resources, the papers on life satisfaction under Science, and the "Mental State Approaches" paper under Policy.

In Lieu of an Environmental Ethic: Beauty, Good Lives and the Preservation of Nature. The Harvard Review of Philosophy (2022). This paper argues that a specifically environmental ethic is neither needed nor perhaps desirable for effecting the change in values for which many environmentalists have rightly called. Rather, familiar values such as beauty, and especially an outlook that regards those values as central aspects of a good life, may be all that is needed. The requisite ethic of appreciation is already embedded to some degree in a wide range of cultures, so no radical shift in values is called for, nor convergence on a tendentious moral framework. But this outlook meets with skepticism from the dominant public ethos, as embodied for instance in mainstream economics. While this paper does not offer a full-blooded defense of an aesthetic grounding for environmental concern, it does suggest that the skepticism is considerably overblown. 

Happiness and the Metaphysics of Affect. Forthcoming in Les Ateliers de l’éthique/The Ethics Forum. Explores and motivates the idea of happiness as a matter of one's emotional condition, where this involves a distinctive category of an individual's functional condition, and centrally involves dispositional states.

The science of well-being: measurement and other issues

I am relatively optimistic about extant measures of well-being, and think improving measurement is vitally important. But there are also deep challenges that have not been fully appreciated by researchers, especially regarding life satisfaction instruments. At present, I suspect our best overall well-being measures are mental health scales, e.g., of depression and anxiety.

How well-being happens (or not)

A central theme here is a kind of contextualism: human psychology is not well-suited to the highly individualized pursuit of well-being, which is substantially something we must do together. See also "Do we know how happy we are?" under Science.

Policy and economics

I am working toward a third monograph following on Pursuit and LivesGood Societies. I take well-being to be a central goal of policy, but one among others including opportunities and justice. Valerie Tiberius and I have argued for a "pragmatic subjectivist" approach to policy, where people's own values should be the standard used for assessing their well-being in policy, whatever the correct theory of well-being is. In practice, I believe this counsels a focus on a plurality of "consensus predictors" of well-being, such as happiness, relationships, rewarding work, and stressors.


Despite popular worries to the contrary, I see well-being policy as an essential tool for avoiding paternalism, though there are certainly tensions with liberty given people's tendency to make serious, predictable mistakes. Anna Alexandrova and I have argued that traditional economic approaches to policy have often been objectionably paternalistic, in some cases precisely by refusing to take account of available information about happiness and other cherished values.
