Here's the thing though (and this will become more clear in my next
paragraph) - a representation of a song/picture/novel/etc *does not
function* as a song/picture/novel/etc.  A computer program is unique
in this aspect - it IS its integral representation.

Not at all!  I think I wasn't clear with my claim.  I am making a
careful distinction between an actual computer program (ie, the data
that my computer actually executes), and the code that we write when
we program.

There are cases when a reverse syllogism is a valid argument.  In
particular, this is a true statement:

Of course, I never said it was necessarily a useful program.
The problem I see with making a distinction is an epistimological one.
How can you ever tell the difference? [1]

I think I might write a piece of software that demonstrates this.
I've been thinking about.  It's very easy to write a shell script that
prints the integer a program makes.

But I couldn't find anything that does the reverse, because the vast
majority of integers almost certainly don't do anything interesting.
But in principle it should be easy.

No - I too accept copyrighting of software for pragmatic reasons.  The
reasons you identifed are really good ones.  It's also the status quo
and it's really hard to get by otherwise.

I just find this to be a very difficult arguement to resolve.  When
someone asked about a distinction I've thought about a lot, I thought
I might stick my idea out into the world ::-)

I am a programmer, though not professionally at this point.  My
degree is in mathematics, philosophy, and computer science.  I guess
you've also figured I'm strong on the philosophy ::-)

I don't deny the creativity in software development at all.  I'm just
busy being creative in other ways right now!


[1] You know some logic - are you familiar with the proof of Godel's
Incompleteness Theorem?  If so, we're at the point after arithmetic
has been Godel-numbered: we can no longer distinguish between an
integer and an arithmetic statement.
