Knowledge about human wellbeing is a central part of ethical knowledge. But it is a neglected topic not only in ethics in general, but also in wellbeing theorizing, which has focused on enumerating the basic elements of wellbeing rather than on how to gauge, foster and maintain wellbeing in actual human lives. I consider the prospects for a procedural approach to wellbeing that sees it as depending on a process of continual adjustment between values, preferences, actions and emotions. The value-fulfilment (...) theory of Valerie Tiberius provides a model for such an approach, but needs to be corrected and supplemented in certain respects. I propose a version of the approach that is only partly, but still significantly procedural, and which does not privilege higher-order mental states. Considering the relevance of such an approach for ethics, I finally suggest that (certain forms of) moral agency may be best analyzed as an intersubjective process of adjustment and fulfilment of values and desires (etc.), and as a process of acquiring and exercising collective moral knowing how.
