Let be be finale of seem. (7)
We keep coming back to this because it's loaded with ideas. Here's another: power rests heavily on one's ability to "seem" powerful to others. If we remove the "seeming," then we likely remove the supposed reality behind the clever disguise. Think of the wizard behind the curtain. When the curtain's gone, all we have left is a meek guy who has a cool machine that throws his voice in all sorts of directions.
