Positive psychology and virtue: Values in action

ABSTRACT

This paper provides an overview of the issues and themes that were discussed on an interdisciplinary panel which occurred at the American Philosophical Association’s pacific division meeting in April of 2017. The panel focused on the connections between the VIA classification of virtues and character strengths in psychology and virtues and the Aristotelian approach to virtue in philosophy. Three key themes emerged from the papers presented at this panel: 1) the nature of the relationship between virtues and character strengths on the VIA model; 2) the extent to which the conceptions of virtues and character strengths are best understood as universal or culturally-embedded; and 3) the reliability of using self-report measurements to measure character strengths. This paper serves to frame papers that resulted from that panel and were incorporated into this special issue of the Journal of Positive Psychology.     

Historical Emissions and the Carbon Budget

How should the world's remaining carbon budget be divided among countries? We assess the role of a fault‐based principle in answering this question. Discussion of the role of historical emissions in dividing the global carbon budget has tended to focus on emissions before 1990. We think that this is in part because 1990 seems so recent, and thus post‐1990 emissions seem to constitute a lesser portion of historical emissions. This point of view was undoubtedly warranted in the early 1990s, when discussion of fault‐based principles in this context began. While this view still has some intuitive force, we find that it and the associated focus on pre‐1990 emissions are now out of date. Emissions since 1990 in fact constitute a large and rapidly increasing proportion of emissions since 1750 – approximately half of the carbon emissions due to fossil fuel use and cement production, at the time of writing. We show that a restricted fault‐based principle, according to which emissions should be divided among countries on the basis of their emissions since 1990, is both viable and powerful. We consider standard objections to a fault‐based principle in this context, how such a principle might more concretely be applied, and its likely implications.     

Less is more: Two- and three-dimensional graphics for data display

Psychologists tend to rely on a few simple graphs for presenting their results. The line chart, scatterplot, and profile plot have their uses, but there are new methods for displaying data which can reveal more. This paper shows several univariate and multivariate displays which can be created on a desktop computer and which reveal the distribution of the data they summarize.     

Global Constraints on Imprecise Credences: Solving Reflection Violations,Belief Inertia,and Other Puzzles

The move to imprecise credence models leaves many formal norms of rationality surprisingly intact, as rational constraints on precise credences are often reinterpreted as constraints on individual elements of a rational agent’s representor. However, constraints on imprecise credences needn’t take this form. Whether an imprecise agent is rational might just as easily depend on global features of her representor. This paper is an extended investigation of global rules of rationality. I begin by distinguishing and defining multiple notions of globalness. Then I use these notions to solve several problems faced by fans of imprecise credences. On behalf of fans of imprecise credences, I respond to the problem of belief inertia, according to which certain imprecise agents are unable to engage in inductive learning. In addition, I answer the objection that that imprecise agents are doomed to violate the rational principle of Reflection.
