I don't know which of the three choices I offered (or None of the Above) McCain would say is the origin of the current notion of What Right Means. But I don't have to think the idea of fixed definitions makes sense to see that they're in practiced used all the time. I feel like I should channel Foucault, and bring in some of his ideas on how we enact definitions of terms and them get bound by them (c.f. "hetero", "criminal", "female"...)
