one does not come to understand our cultures by understanding how an individual Homo sapiens organism works, and then scaling up; one understands how a person works by understanding our cultures and our multiple roles therein. And there is no place for a self in the story that these analogies suggest. We are too bound up with others for that. This means that in order to understand who we are, and what our lives are, we must take the social level of analysis at least as seriously as we do the psychological and the biological.
