Dear Toby, your choice of example is very unfortunate. Mac Lane wrote that category theory was invented to define functor, and that functor was invented to define "natural" transformation.
Yes, I know; that was quite deliberate. I'm afraid that I no longer have any idea how to communicate with you on this matter. I'm sure that you don't understand my opinion, and it's clear that I must not understand yours, but beyond that I have no idea what upsets you, and I'm not going to worry about it any more. --Toby [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
