The results in consciousness will be to gain a new understanding of the world. The savage who sees and hears a cinema for the first time may believe that he is seeing flesh-and-blood people, but the civilized man who sees and hears the same film will know that he is seeing only their pictures. Again, whereas one man will believe the picture-people's environment to be of the same fixed size in space as the screen on which the perspective appears, another will know that--being made only of light and light in itself being quite formless--the perception of their spatial character is really a variable one. Great as is the difference in understanding between these two men, the difference between the world-understanding of the civilized man and that of the man possessed of this insight is even greater.
