But the narrow-scope interpretation appears to leave Kant’s view  vulnerable to “detachment” objections.  Suppose you will some immoral  end but, irrationally, don’t will the immoral means you believe  necessary to carry out this immoral end.  On the narrow-scope  interpretation, reason would require that you will the immoral means.   But that seems implausible.  At the very least, it would lead to  something Kant wouldn’t accept: reason issuing contradictory commands.   Your willing the immoral means would be required by a hypothetical  imperative but forbidden by the categorical imperative (Hill 1973, 436).
