It's all foolishness-- to think that we can settle normative questions with positive arguments. I mean, sometimes positive arguments can influence us to change our minds, but the normative doesn't flow from some kind of axiomatic interpretation of positive statements and facts. We can only start to get close where we can agree on outcomes we want-- then we can start to weigh policies and see whether they get us closer to them.
