  This is an over-simplification of a hotly-debated argument on some of
the foundational issues in the philosophy of science.  There is a distinction
between empirical notions and theoretical terms.  An atom is a theoretical
term.  It does, however, have an empirical enterpretation by linking it to
the observable results of experiments from which we can infer the existance
of the physical thing that we intend to model by our concept "atom".  

  If you hold with a subjectivist opinion of science (cf. Thomas Kuhn), then
in a sense the atom is there because you are looking for it.  From an
objective standpoint (cf. Israel Sheffler), the physical thing is there,
though our model of it (our concept "atom") will be very fluid and changeable
as our level of knowledge increases.  Several distinctions are implicit in
the debate.  There is the difference between the product, and process of
science.  The difference between the existent (the actual, real thing), and
what we know about it.  There is also the difference between connotational and
denotational semantics of scientific terms and concepts.  Funny thing is
that the "unexpectedness" of some discoveries is itself is a strong argument
for the objective stance.  If you create what you see, why would you ever
see something you didn't expect to see?

  Perhaps the best resolution to the debate comes from the viewpoint of Hume
when he commented on speculative philosophy:

  "When we run over libraries, persuaded of these principles, what havoc
   must we make?  If we take in our hand any volume; of divinity or school
   metaphysics, for instance; let us ask, `Does it contain any abstract
   reasoning concerning quantity or number?'  No.  `Does it contain any
   experimental reasoning concerning matter of fact and existance?'
   No.

   Commit it then to the flames: for it can contain nothing but
   sophistry and illusion."

  Modern interpretation?  Don't bug me with meaningless philosophical crud.

I create the entirety of the programs I write, all out of conscious
thought.  Yet the output of these programs is often something I didn't
expect to see.

	Just because you create something does not mean that you can
	predict it outcome, even if you create the rules that it must
	follow to arrive at that outcome.  Further, just because some part
	of your mind creats an event, there is no reason to believe that
	any other part of your mind can or will access that information
	and expect it to have been created.
