A Virtue Theoretic Approach to Practical Knowledge

Intentional action is, in some sense, non-accidental. One prima facie promising way to account for this platitude is through Anscombe’s Practical Knowledge Principle (PKP), which holds that intentionally doing something requires knowing that you are doing it intentionally. While (PKP) offers strong anti-luck credentials, it has the problematic implication that intentional action becomes luminous. This chapter critiques some existing attempts to weaken (PKP) and introduces an alternative rooted in performance-theoretic virtue epistemology. The proposed framework distinguishes between two grades of intentional action, each with different levels of protection against luck in action. Both involve knowledge of what we are doing, but in different ways: the first grade requires externalist knowledge secured by apt practical belief, while the second – reflective or R-intentional action – demands also second-order knowledge of one’s abilities and their reliability in the relevant performance conditions. This two-tiered, virtue theoretic approach, which gives knowledge of abilities a central role at the second order, is shown to offer several explanatory advantages in action theory.
