 The above argument against DDS requires the assumption that if x is perfectly F, then x is F. This is highly plausible but not quite obvious, since as Barry Miller (1996, Ch. 5) argues, ‘perfect’ might be an alienans adjective. An alienans adjective is one that shifts, alters, alienates, the sense of the noun that it modifies. Thus ‘decoy’ in ‘decoy duck’ is an alienans adjective: from the fact that a thing is a decoy duck one cannot infer that it is a duck in the way in which one can infer from the fact that a thing is a male duck that it is a duck. So if ‘perfectly’ in ‘perfectly powerful’ is an alienans adjective, then God can be perfectly powerful without being powerful, and the above objection to DDS collapses.
