 Nonetheless, it is possible that something can be built on the central idea of the argument, which seems to be this: As long as we think we can act for reasons based on the value of things, but at the same time reject any realism about that value applying to things independently of us, then we must be treated as the source of value and in a way that makes rational choice possible. We can therefore see Korsgaard’s second argument as attempting something along these lines, using her notion of practical identity to perhaps avoid the two problems we have identified with the Kantian argument.
