ABSTRACTThis paper challenges a frequent objection to conceptualizing virtues as skills, which is that skills are merely capacities to act well, while virtues additionally require being properly motivated to act well. I discuss several cases that purport to show the supposed motivational difference by drawing our attention to the differing intuitions we have about virtues and skills. However, this putative difference between virtue and skill disappears when we switch our focus in the skill examples from the performance to the performer. (...) The ends of a practice can be used to judge not only the skilfulness of a performance, but also the motivational commitment of the performer. Being virtuous requires both acting well and being properly motivated to do so, which can be captured by viewing virtues as the moral subset of skills. In claiming this, though, I resist the idea that there is no element in virtue that is not found in other skills. Virtue requires being practically wise about how practices fit into a... (shrink)

Underdetermination of theory choice claims that empirical evidence fails to provide sufficient grounds for choosing a theory over its rivals. We explore the epistemological and methodological significance of this thesis by utilising a classificatory scheme to situate three arguments that purport to establish its plausibility. Proponents of these three arguments, W.V.O Quine, John Earman, and Kyle Stanford, use different premises to arrive at the conclusion that theory choice is empirically underdetermined and their classification along the proposed schema brings out the (...) variety in underdetermination arguments and the historical trajectory of the thesis. Although the epistemological significance of underdetermination—it is seen as undermining the doctrine of scientific realism—is widely discussed in the literature, Quine understood the acceptance of the thesis as interrogating the attitude one is justified in adopting towards rival theories. We argue that sticking with one’s own theory in the face of underdetermination leads to a distinct type of disagreement, which we present as the methodological significance of underdetermination. The examination of the methodological significance of underdetermination allows us to propose weak underdetermination as a philosophically interesting variant of underdetermination. (shrink)

This paper challenges the appeal to theory virtues in theory choice as well as the appeal to the intellectual and moral virtues of an agent as determining unique choices between empirically equivalent theories. After arguing that theoretical virtues do not determine the choice of one theory at the expense of another theory, I argue that nor does the appeal to intellectual and moral virtues single out one agent, who defends a particular theory, and exclude another agent defending an alternative theory. (...) I analyse Duhem’s concept of good sense and its recent interpretation in terms of virtue epistemology. I argue that the virtue epistemological interpretation does not show how good sense leads to conclusive choices and scientific progress. (shrink)

Experiments are actions, performed in order to gain information. Like other acts, there are virtues of performing them well. I discuss one virtue of experimentation, that of knowing how to trade its information-gaining potential against other goods.
