The following is reposted from the Teach-Econ network.  Much of the  
discussion pertains to the teaching of Economic History, as well.

Dear James 
 
 
        Why is it that statements such as these need be positive. 
It seesm that some of the most important economic ideas have always  
come from a viewpoint that is normative.  If you check Colanders 
Principles book 
 it seems to me that he recognizes that economists 
are normative and that there is nothing wrong with being so.  I  
know that I am normative and carry a lot of views into any type 
of teaching or research I conduct.  The very things that we teach 
are oftern determined by normative views we hold.   
 
        I would like to hear you feelings on the issue.  I would 
also like to hear the feelings of the rest of the group 
 
Thank you

In response to Loren Rice's "I would also like to hear the feelings of 
the rest of the group": 
 
I consider myself to be quite heterodox with very strong affinities for 
institutionalism (but not new instittutionalism).  I believe that the 
positive-normative dichotomy is largely a false one--a proposition that 
institutionalists have been arguing for many decades.  Very early on 
(day 1 or 2) I offer Nietzsche's ".....there are no facts, only 
interpretations" as a point of departure for discussing this issue. 
I always also read to them the following passage from Gary Zukav's 
_The Dancing Wu Li Masters: An Overview of the New Physics_ (p. 310) 
 
"Reality" is what we take to be true.  What we take to be true is what 
we believe.  What we believe is based upon our perceptions.  What we 
perceive depends on what we look for.  What we look for depends upon 
what we think.  What we think depends upon what we perceive.  What we 
perceive determines what we believe.  What we believe determines what  
we take to be true.  What we take to be true is our reality.

I agree with James Cover on this, but for those who don't: 
 
The distinction between positive and normative economics is 
something like the distinction between the news columns and the 
editorial columns in a newspaper.  We all recognize that there 
may be opinion in the news columns and reporting in the editorial 
columns -- but the reason for having the distinction is to help 
the reader and the writer agree on an implicit set of 
expectations.  The reader expects to see a balance among 
conflicting views in the news columns, but has no expectation of 
balance when reading an opinion column.  The reader expects it to 
be, well, opinionated.  In a similar way, there are value 
judgments in (and around) "positive economics," and there are 
often empirical observations in "normative economics."  But the 
labels are still useful so that reader and writer agree on 
whether the basic task is to discover something about the world 
-- or not. 
 
So even if you think the distinction between positive and 
normative economics doesn't work, it can be a useful convention 
to let the student or reader know what's coming.

I write to comment on the issue of ethics and economics.  There is, I 
believe, a dimension of this issue that in some sense transcends the 
standard discourse of positive v. normative.  In that discourse the question 
with respect to the role of ethics is debated in the positive v normative 
terms of efficiency versus the fairness (of initial endowments, 
policies, and outcomes).  But there is another more fundamental question of 
ethics that does not lend itself to this demarcation from efficiency.  That 
is the question as to what kind of social ethics must be in place if the 
market system is to function with all the elegance we advertise under the 
brand name "Invisible Hand".  We can turn to the parent of our company for 
an answer. 
  The foundation of Adam Smith's ideal liberal (small l) vision 
of a free market economy coordinating the choices of autonomous individuals 
in an efficient and thus socially fruitful way is the assumption that all 
of those individuals must share a common definition of and commitment to 
justice.  Obviously not society had or even can reach that limiting case, but 
Smith believed that humankind could approximate that case as various societies 
evolved.  He believed that social evolution could be a maturation process, but 
that the development of social maturity depended on values coevolving with the 
material conditions of society.  For any given society the possibility of 
maturation depended on and is limited by the degree to which that 
society is capable of developing and inculcating more mature social values. 
There some powerful and terribly neglected lessons embodied in Smith's vision. 
  If there is a serious weakness in the story we tell our students, it is 
our failure to note the fundamental importance of this common ethical 
commitment.  Often students leave with the Mandevillian notion that greed 
is good instead of the more rich Smithian notion that self-interest, 
properly balanced with justice and benevolence, is a wonderful spring for 
constructive competition and thus for realizing the best of our individual and 
social potential.

I agree  that many of the results we get in economics are  
untestable. Writers like McCloskey (1985) and Summers(1993) seem to  
me to be arguing very persuasively that economics (and I would think  
any science) is about argument and persuasion not 'testable' proof. 
      
The 'what is' (as opposed to 'what should ') aspect of positivism is  
I believe a useful distinction. Introspection makes it obvious  
to me that reminding myself to focus on the positive aspect (ie to  
focus on 'what is') protects me from confusing wishing with analysis.  
I might add to this argument by example or survey but such  
introspection is of course untestable.
