Is sthere any was of cleaning up the commutative diagram...unfortunately the AMS CD package doesn't work. One could convert to JPEG I suppose (YUCK)
PLEASE o please could we get rid of "Philosophy" as a title head? When somebody says "My philosophy of the matter is.." I usually expect complete garbage to follow. This is not an attack on Philosophy, quite the contrary, it's an attack on the continual devaluation of Philosophy as a subject of intellectual endeavor. To use it as synonym for vagueness is unfortunate. User:CSTAR
Well, philosophy is no more. It's quite an old article by WP standards, and probably needs work. More about representable functors, eg in homotopy theory, would be handy also.

D --> Fun(Dop,Set)

The original seemed backwards to me the way things were stated. Please let me know if I screwed it up (highly possible, as things like covariant functors into categories of contravariant functors really make my head hurt). -- Fropuff 16:55, 2004 Jul 20 (UTC)
