    <title>Cybernetics</title>

    <description>
&lt;P&gt;A science which seems to have dissolved into the others.  A lot of good
science was done under this banner; it just doesn't seem to hold together.
Cybernetics helped give rise to some new fields, like &lt;a
href=&quot;cognitive-science.html&quot;&gt;cognitive science&lt;/a&gt;; it disseminated about a
dozen ideas and bits of applied math which have proved useful (in, e.g., &lt;a
href=&quot;neuroscience.html&quot;&gt;neurobiology&lt;/a&gt;); but what else?  As a study of
abstract machines in general, it becomes identical with dynamics, or
computation theory, or some amalgam of both; algebra, even.  As a more limited
science of &quot;communication and control&quot; it suffers from the fact that
communication and control in animals is, when you get down to blood and guts,
rather different from communication and control in machines, and neither
resembles the mechanisms of C&amp;amp;C in society.  This is not to say that there
are no similarities; of course there are; but they're at the very general level
of things like &quot;feedback&quot; and &quot;you must have an information channel,&quot; and
pretty much exhausted by ideas which are now common currency in many particular
fields.  And even then, animals have &lt;a href=&quot;seriatim.html&quot;&gt;control without
feedback&lt;/a&gt;.  It may be that we haven't exhausted the potential of a science
of communication and control, but I think at this point the burden of proof
would be on the optimists.

&lt;P&gt;Dissolved?  Not entirely.  There's an old joke that if you're not part of
the solution, you're part of the precipitate, and not everything associated
with cybernetics has gone into solution.  Caked on the bottom of the reaction
vessel we find: A prefix which seems indispensible to marketroids; the
occassion for a great deal of vaporizing in the social sciences and humanities;
and a peculiarly navel-gazing sub-sect of &lt;a href=&quot;systems-theory.html&quot;&gt;systems
theory&lt;/a&gt;, which isn't exactly God's gift to the advancement of learning in
the first place.

&lt;P&gt;History --- &lt;a href=&quot;wiener.html&quot;&gt;Wiener&lt;/a&gt;, &lt;a
href=&quot;ashby.html&quot;&gt;Ashby&lt;/a&gt;, Herbert &lt;a href=&quot;simon.html&quot;&gt;Simon&lt;/a&gt;.  Origins
in &lt;a href=&quot;mathematical-logic.html&quot;&gt;mathematical logic&lt;/a&gt;, &lt;a
href=&quot;claude-bernard.html&quot;&gt;physiology&lt;/a&gt;, engineering, &lt;A
href=&quot;stat-mech.html&quot;&gt;statistical mechanics&lt;/a&gt;.  Predecessors --- Rashevsky,
Lotka, Cannon, Sherrington (?).  Popular and semi-popular views.  Metaphorical
uses.  Appropriation.  Descendants --- &lt;a href=&quot;ai.html&quot;&gt;artificial
intelligence&lt;/a&gt;, &lt;a href=&quot;systems-theory.html&quot;&gt;systems theory&lt;/a&gt;, &lt;a
href=&quot;chaos.html&quot;&gt;dynamics&lt;/a&gt;, &lt;a href=&quot;complexity.html&quot;&gt;complexity&lt;/a&gt;, &lt;a
href=&quot;prigogine.html&quot;&gt;Prigoginism&lt;/a&gt;.  And the &lt;cite&gt;&lt;a

but from just skimming it appears that Kelly's math is very limited, which puts
him in a damn poor position to pontificate about these matters.  Certainly he
cites with respect some books (e.g. &lt;cite&gt;Evolution as Entropy&lt;/cite&gt;) which no
one with enough math not to be intimidated by phrases like &quot;evolution has a
topological structure, and consequently an entropy&quot; would bother with.  I
really ought to finish it, though, and shoot it after a fair trial.  Mr. Kelly
is the executive editor of &lt;cite&gt;Wired,&lt;/cite&gt; which gave this book an ecstatic
review, and a blurb for the cover of the paperback.  There's no promotion like
self-promotion.  Cf. a &lt;a
