Situationists (e.g., Doris in Lack of character: personality and moral behavior, Cambridge University Press, Cambridge, 2002; Harman in Proc Aristot Soc 99:315–331, 1999. 10.2307/4545312), with reference to empirical work in psychology, have called into question the predictive and explanatory power of character traits and on this basis have criticized the empirical adequacy of moral virtue. More recently, Alfano (Philos Q 62(247):223–249, 2012; Character as moral fiction, Cambridge University Press, Cambridge, 2013) has extended the situationist critique from virtue ethics to virtue (...) epistemology. On the line he advances, virtue responsibilism—the view that intellectual character traits play an important part in traditional and untraditional epistemological inquiries—is criticized as empirically inadequate in light of the extent to which individuals are shown to be susceptible to seemingly trivial and epistemically irrelevant situational influences. Alfano’s attempted redeployment of the situationist challenge to virtue responsibilism is on closer inspection not as straightforward as he claims. It is granted that the empirical adequacy of virtue responsibilism will be eventually threatened if it can be shown that virtuous motivation is, in light of situational factors, causally ineffective. As it turns out, various psychological studies which situationists have overlooked, suggest that virtuous motivation is causally efficacious in a way that favours the position of the virtue responsibilist over the situationist. In the first part of this paper, I outline the hard core of virtue theory: both a rich motivation requirement, and a commitment to the inherent relation between virtue and a good life; then I assess whether these are undermined by situationist criticism. I address the confusion of the existing debate, and the conclusion drawn is that virtue theory ultimately remains unscathed. In the second part of my paper I defend the empirical adequacy of virtue theory based on self-determination theory. When we afford closer attention to studies on the orientation of our motivation, it becomes clear how the dynamics of our motivation have a tremendous influence on desirable behavioural outcomes: a good life.
