In response to Pei Wangs post of 10/4/2007 3:13 PM
Thanks for giving us a pointer so such inside info.
Googling for the article you listed I found
1. The Logic of Categorization, by PeiWang at
http://nars.wang.googlepages.com/wang.categorization.pdf FOR FREE; and
2. A logic of categorization Authors: Wang, Pei; Hofstadter,
Douglas; Source: Journal of Experimental & Theoretical Artificial
Intelligence <http://www.ingentaconnect.com/content/tandf/teta> , Volume
18, Number 2, June 2006 , pp. 193-213(21) FOR $46.92
Is the free one roughly as good as the $46.92 one, and, if not, are you
allowed to send me a copy of the better one for free?

I guess I do know more on this topic, but it is a long story for which I
don't have the time to tell. Hopefully the following paper can answer some
of the questions:
A logic of categorization
Pei Wang and Douglas Hofstadter

No.2, Pages 193-213, 2006
