"Perhaps, thinks Hauser, I could produce a series of squares moving in almost indiscernable increments from black to gray, and substitute them consecutively  for each square on the table.  After a number of careful substitutions, the black square would wither to gray and the gray square would ripen to black.  Gahern might realize something was happening, but perhaps would not understand what.  Suddenly he would perceive that the square he thought gray was black and the square he thought black gray.
And what, Hauser wonders, regarding his reflection in a pane of glass, would be the point of that?"
