To make Kirby's point, I guess it depends on how one defines "in math".  
"Math is" cannot reasonably be defined to exclude how math is, in many 
cases, practiced. And math *is* practiced within the OO paradigm.  
Extensively, expansively, etc. Having gotten to where it has in the 
struggle for the survival of ideas, one needs to presume it has some 
inherent strength - of the kind that needs to be respected.

But where Kirby seems to see a movement from one paradigm to another as 
progress, I seem to prefer to see an inclusive expansion of the existing 
paradigm as such.
