The developing body of empirical work on the "Gettier effect" indicates that, in general, the presence of a Gettier-type structure in a case makes participants less likely to attribute knowledge in that case. But is that a sufficient reason to diverge from a JTB theory of knowledge? I argue that considerations of good model selection, and worries about noise and overfitting, should lead us to consider that a live, open question. The Gettier effect is perhaps so transient, and so sensitive to other, epistemologically-inappropriate factors, that it raises the question of whether it ought to be counted as something to include in our theories -- or as a piece of noise to be excluded from them.

In his Experiments in Ethics, Appiah focuses mostly on the dimension of naturalism as a naturalism of deprivation - naturalism’s apparent robbing us of aspects of the world that we had held dear. The aim of this paper is to remind him of that naturalism has a dimension of plenitude as well - its capacity to enrich our conception of the world as well. With regard to character, we argue that scientific psychology can help provide a conception of character as dynamic, in a way that may preserve many key aspects of eudaimonistic ethics from the situationists’ challenge. With regard to intuition, we address Appiah’s worry that naturalistic explanations of the sources of our intuitions may leave us feeling that those intuitions have been thereby debunked. We suggest that it may be that feeling of debunking that should itself be debunked
