Kory, at least here, argued against the null koan.

As is obvious from my previous answer, I don't think this is
ambiguous; a koan with no blue pyramids obviously has all (ie, none)
of its blue pyramids upright. Zendo pretty much breaks down (at least
in terms of having a common rule system) if you don't treat "all" and
inequalities as covering the zero case--rules assuming that "all" is
false when nothing of the set is present rachet up in complexity for
players who take the mathematical view.
