In her excellent critique of my book Self to Self (2006), Catriona Mackenzie highlights three gaps in my view of the self. First, my effort to distinguish among different applications of the concept 'self' is not matched by any attempt to explain the interactions among the selves so distinguished. Second, in analyzing practical reasoning as aimed at self-understanding, I speak sometimes of causal-psychological understanding (e.g. in the paper titled 'The Centered Self') and sometimes of narrative self-understanding (e.g. in 'The Self (...) as Narrator'), but I never explain how these two modes of self-understanding are related. Third, I never explain how my account of autonomous agency can be reconciled with my interpretation of Kant's (e.g., in 'A Brief Introduction to Kantian Ethics'). In this reply to Mackenzie, I agree with her about all three of these gaps, and I offer some (admittedly incomplete) ideas about how they might be filled. (shrink)
