　　It seems to me that the roots of the paradox reside in the concept of the frame. When we look at a realistic painting—a portrait of a historical figure—we accept by convention that the portrait represents a real person and actual objects. When that convention is denied, as in Magritte’s pipe paintings, the point is not to remind us that paintings are not real. That much is true but trivial. The point is to challenge the belief that everything outside the frame is real.
