Actually, technically, Zhaozhou answered "Mu", which doesn't have a
precise meaning in English but approximates as "No-thing".  It does not
compute.  Or in true computerese, NaN.

Note well that this suggests that there may well be a semantic mapping
between some of the famous old koans and axiomatic set theory augmented
by the addition of a "null set" -- an symbolic construct for "not a set"
(not in the set theory), not the "empty set" (which is always in the set
theory).  The null set provides an elegant solution to some of the
problems with self-referentiality and paradox.  See my draft online:

Since I finally finished (today) "The Book of Lilith" on lulu, I'm
getting back to Axioms and will see if I can knock it off now that I
have David Mackay's Information Theory, Inference, and Learning
Algorithms, which, by the way, should probably be required reading for
all computer science, math-stats, math-philosopher types.  Along with
E.T. Jaynes Probability Theory as Extended Logic, from which part of it
is derived.

My own favorite version of this koan is:

And finally, a monk asked Zhaozhou, "Does the Buddha have dog-nature
or not".  Zhaozhou answered, "Would that be yellow lab, bulldog, or
chihuahua?"
