Abstract: 
When Heinz von Foerster coined the term 
“second order cybernetics,” his goal was to include the observer in the 
domain of science.  This was a fundamental change in the conception of 
science, and Heinz encountered stiff opposition. 
 One consequence of including the observer would be to extend 
cybernetics (and science) into the domain of ethics.  Scientists had 
previously sought to be objective.  Including the observer made science a
 subjective enterprise.  This suggestion was strongly
 resisted by Heinz’s colleagues in the UIUC College of Engineering and 
elsewhere in the U.S. academic community.
Since
 Heinz retired and moved to California, the people involved in 
cybernetics in the U.S. have been mostly social scientists.  Rather than
 people with backgrounds in neurophysiology, psychology,
 mathematics and philosophy, those interested in cybernetics tended to 
be therapists, management scientists, sociologists and people concerned 
with design.  Including the observer in science led to interest in 
scientific theories as part of social systems. 
 Several conceptions of second order science have now been formulated.  
If we use the correspondence principle (i.e., every new theory should 
reduce to the old theory to which it corresponds for those cases in 
which the old theory is known to hold), we can
 say that two dimensions have been added to the conception of science:  
a) amount of attention paid to the observer, and b) the amount of effect
 of a theory on the phenomenon described.
