Perhaps personality traits substantially influence one’s philosophically relevant intuitions. This suggestion is not only possible, it is consistent with a growing body of empirical research: Personality traits have been shown to be systematically related to diverse intuitions concerning some fundamental philosophical debates. We argue that this fact, in conjunction with the plausible principle that almost all adequate philosophical views should take into account all available and relevant evidence, calls into question some prominent approaches to traditional philosophical projects. To this end, (...) we present the Philosophical Personality Argument (PPA). We explain how it supports the growing body of evidence challenging some of the uses of intuitions in philosophy, and we defend it from some criticisms of empirically based worries about intuitions in philosophy. We conclude that the current evidence indicates that the PPA is sound, and thus many traditional philosophical projects that use intuitions must become substantially more empirically oriented.

This paper develops an empirical argument that the rejection of moral objectivity leaves important features of moral judgment intact. In each of five reported experiments, a number of participants endorsed a nonobjectivist claim about a canonical moral violation. In four of these experiments, participants were also given a standard measure of moral judgment, the moral/conventional task. In all four studies, participants who respond as nonobjectivists about canonical moral violations still treat such violations in typical ways on the moral/conventional task. In (...) particular, participants who give moral nonobjectivist responses still draw a clear distinction between canonical moral and conventional violations. Thus there is some reason to think that many of the central characteristics of moral judgment are preserved in the absence of a commitment to moral objectivity. (shrink)

This groundbreaking handbook of character strengths and virtues is the first progress report from a prestigious group of researchers who have undertaken the systematic classification and measurement of widely valued positive traits. Character Strengths and Virtues classifies twenty-four specific strengths under six broad virtues that consistently emerge across history and culture. This book demands the attention of anyone interested in psychology and what it can teach about the good life.

We review evidence showing that disagreement in folk and expert philosophical intuitions can be predicted by global, heritable personality traits. The review focuses on recent studies of intuitions about free will, ethics, and intentional action. These findings are philosophically important because they suggest that while some projects cannot be done, other projects must take individual differences in philosophical character into account. But care needs to be taken when interpreting the implications of these individual differences. We illustrate one way that these (...) differences have been abused. We then illustrate two ways that these findings can be legitimately used to help illuminate philosophical issues. Given the large and readily available body of evidence, neglect of persistent and predictable philosophical differences is irresponsible. (shrink)

What is the nature of moral behavior? According to the study of bounded rationality, it results not from character traits or rational deliberation alone, but from the interplay between mind and environment. In this view, moral behavior is based on pragmatic social heuristics rather than moral rules or maximization principles. These social heuristics are not good or bad per se, but solely in relation to the environments in which they are used. This has methodological implications for the study of morality: (...) Behavior needs to be studied in social groups as well as in isolation, in natural environments as well as in labs. It also has implications for moral policy: Only by accepting the fact that behavior is a function of both mind and environmental structures can realistic prescriptive means of achieving moral goals be developed.

It is commonly claimed that fully virtuous individuals cannot be ignorant and that everyday intuitions support this fact. Others maintain that there are virtues of ignorance and most people recognize them. Both views cannot be correct. We report evidence from three experiments suggesting that ignorance does not rule out folk attributions of virtue. Additionally, results show that many of these judgments can be predicted by one’s emotional stability—a heritable personality trait. We argue that these results are philosophically important for the (...) study of virtue and we discuss some of the ways individual differences may inform and facilitate current debates in ethics. We close with a cautionary argument detailing the risks of discounting some intuitions simply because they are associated with seemingly less desirable personality traits. (shrink)

Evaluational internalism holds that only features internal to agency (e.g., motivation) are relevant to attributions of virtue [Slote, M. (2001). Morals from motives. Oxford: Oxford University Press]. Evaluational externalism holds that only features external to agency (e.g., consequences) are relevant to attributions of virtue [Driver, J. (2001). Uneasy virtue. Cambridge: Cambridge University Press]. Many evaluational externalists and internalists claim that their view best accords with philosophically naïve (i.e., folk) intuitions, and that accordance provides argumentative support for their view. Evaluational internalism (...) and externalism are incompatible views and therefore it is impossible that both views are supported by most folk intuitions. In four experiments, we present evidence that neither pure evaluational internalism nor pure evaluational externalism accurately capture some relevant folk intuitions about virtue. However, our experiments suggest external factors are vastly more important than internal factors for folk attributions of virtue. While these data do not entail that evaluational internalism and externalism about virtue are false, they situate important argumentative burdens, constrain philosophical theory about virtue, and illustrate a valuable method that could foster more efficient progress in ethics.
