IAN: A black-and-white newspaper photograph is a
collection of individual dots, but the collective
entity is more the sum of the individuals, since
the same dots in any other ordering would not
be the collective entity that is "the photo."
I believe that that situation -- where the whole
is greater (has something more) than the sum of
the parts -- defines "the collective entity."
So the question is: Is the photo an illusion?
If yes, the collective entity is an illusion.
If no, then the collective entity is real.
Dick: The picture is actually in our perception, not on the paper.
