<DIV><FONT face=Arial size=2>Dear FISers,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have no difficulty in understanding Loet's
approach as measuring <STRONG>one form</STRONG> of interdisciplinarity. However,
it requires well-defined quantitative entities - classes, categories and journal
articles to which they apply. I thus do not think that it exhausts the
possibilities of the informational domain with regard to
disciplines. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When John C. talks about "references crossing
ecology, management and poltical science", what is of interest to me and perhaps
others is the 'substance' so to speak of the crossing. To make things difficult
(rather than easy for a change), let us assume that this substance includes, but
is not limited to common assumptions and common attitudes. (My informational
exchanges today are more interdisciplinary because I am paying more attention to
the way in which information is processed in the different
disciplines.)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The task then becomes to express the 'substance' in
informational terms. What informational terms are possible that are
<STRONG>not</STRONG> numbers or <EM>ad hoc</EM> Peircean categories? The
first thing I see is that the corresponding logic and category theory must
be non-standard or it will miss the interactions and overlaps between
disciplines. The next thing might be to change to a process perspective, looking
at the way in which the disciplines, considered as informational
entities, influence one another, and find some formal but non-mathematical
language for referring to this. Are there any suggestions for such a
language?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Looking over what I just wrote off the top of my
head, I note that I used the term 'way' twice. Does this suggest a new role for
the informational domain?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Cheers,</FONT></DIV>
