Abstract

A central idea in Anscombe's philosophy of action is that of practical knowledge, the formally distinctive knowledge a person has of what she is intentionally doing. Anscombe also discusses 'practical truth', an idea she borrows from Aristotle, and which on her interpretation is a kind of truth whose bearer is not thought or language, but action. What is the relationship between practical knowledge and practical truth? What we might call the 'Simple View' of this relationship holds that practical knowledge is essentially knowledge of practical truth. But the Simple View isn't obviously available, since we have practical knowledge of all of our intentional actions, whereas an action manifests practical truth in Aristotle's sense only if it is a case of doing or living well. I suggest that we distinguish a thicker ethical version and a thinner action-theoretical version of each notion. This allows us to maintain a - complex - version of the Simple View, on which practical knowledge in the thick ethical sense is knowledge of practical truth in the thick ethical sense, and practical knowledge in the thin action-theoretical sense is knowledge of practical truth in the thin action-theoretical sense. Although Anscombe did not make these distinctions explicitly, I argue that she nevertheless commits herself to them in her discussion.
