This is the book I have that an Introduction of Category Theory. Probably
the best book I've read on the subject. Cambridge Press-not difficult-lots
of examples and pictures!

/dp/0521478170

 

SHORT SUMMARY: Instead of defining a set by the elements it has (the
objects), define the rules for the elements (the properties) and deduce the
elements of the set. This prevents Russell's Paradox.

We've knocked around the term Category Theory a bit lately, so I  

started looking into it a bit.  This seems to be a reasonable  

starting place:

   http://en.wikipedia.org/wiki/Category_theory

 

Has anyone used this in complexity science work?  Or semantic web  

work?  Or anything else?  :)

 

I know Amazon turns up Russell Standish's book first in a search for  

category theory!
