[comp.ai.digest] What is science

Rauschelbach@HIS-PHOENIX-MULTICS.ARPA.UUCP (07/07/87)

I normally only observe this discussion, but Don Norman's pomposity
struck a nerve.  The first objection I have is to his statement that
mathematics and philosophy are not sciences "in the normal
interpretation of the word." The Webster's definition (a fairly normal
interpretation) is:  "accumulated knowledge systematized and formulated
with reference to the discovery of general truths or the operation of
general laws." This certainly applies to both.

The next problem is his statement that AI people think they're
scientists.  He seemed to believe that it was a science until Nils Nilsson
told him the obvious. AI, like it's name implies, is a product, not a
phenomenon, not an occurence of nature to be described. The problem is the
creation of a product, an engineering problem. The preservation of theory is
far from an engineer's mind. The engineer uses theory to describe possible
solutions.  If an engineer comes across a possible solution that has not been
addressed by theory, s/he may get his hands a little dirty before the
"scientists" take control of it. It seems to me that much of the talk in this
discussion is of a hypothetical nature, one of the elements of THE SCIENTIFIC
METHOD he was defending.  This is a good place for that portion of the
method, as well as statement of the problem. The experimentation is left to
the psychologists, neurologists, etc.  I see no one but scientists claiming
to be scientists, and I hear AI people shouting, "Yeah, but how do you code
it?" or "What doohickey will do that?"  Implementation of theory. I have also
read discussion of the testing of implementation. Come to think of it,
engineering also fits the definition of science.

Both things, implementation and theory have been and should be discussed here.
If they intermingle, this can only be healthy, even if somewhat confusing. I
hope we can both get down off our respective high horses now.
