In defense of hard-line replies to the multiple-case manipulation argument

I defend a hard-line reply to Derk Pereboom's four-case manipulation argument. Pereboom accuses compatibilists who take a hard-line reply to his manipulation argument of adopting inappropriate initial attitudes towards the cases central to his argument. If Pereboom is correct he has shown that a hard-line response is inadequate. Fortunately for the compatibilist, Pereboom's list of appropriate initial attitudes is incomplete and at least one of the initial attitudes he leaves out provides room for a revised hard-line reply to be successfully mounted against the multiple-case argument.
