Abstract
In this paper, we considered several variants of the internal-external principle (IEP), and showed that each was susceptible to counterexamples. In the final section of the paper, we showed that our weakening of IEP has significant implications for the wrongness of interferences in the Practical Cases. We showed that on Conditionalized Autonomy Variant, many instances of the Practical Cases do not have special wrongness. Those who hold that interferences in these Practical Cases are particularly morally problematic even when the altered desires are all-things-considered disvaluable should either provide a different explanation for the wrongness of these interferences, or give up the view that these interferences are in one respect more pro tanto wrong than the external frustration of the same desires.
