 Korsgaard’s response comes in three laps. First, she inherits from Wittgenstein the thought that normativity involves the possibility of correction, and she infers that if there is to be any normativity, it must be possible to be in violation of a standard. Now, you can be counted as in violation of a standard only if you can’t simply shrug the correction off. But if you can switch the kind an item counts as belonging to, at will, then you can shrug off any standard and any correction; as Korsgaard puts it, nothing will be defective, ‘everything will just be different.’ (E.g., ‘I’ve decided I’m not an agent but a slacker, so the standards for agents don’t apply to me.’) Thus we must take there to be kinds such that you can’t just shrug and say that you don’t see why the constitutive standards of the kind apply. This first lap of the argument has the look and feel of an existence proof, and of softening up; in particular, it doesn’t purport to show that the twin concepts, ‘action’ and ‘agent,’ are among these privileged kinds (Korsgaard 2009, sec. 2.1.8).
