This is great fun, Joe. The linguistic expression was never meant to
be formally rigorous. The Hindu "neti-neti" actually means, simply,
not this, not that. My intention, when I wrote:
> What is Zen? Mu. What is not-Zen? Mu.
>
> Neither this, nor that, nor [neither this nor that]
was to suggest to the reader the need to eliminate all dualistic thinking,
i.e. that any and all conceptual distinctions must collapse, and with them
thinking itself, to experience the "meaning" of anything. The verbal state-
ment taken literally is not even a logically correct rendering of "neti-neti".
My point was simply that the exclusiveNOR's in the original could be
simplified to precisely the expression you suggested:
[- a . - b]
While I will admit to an equivocation in the original regarding the use of
exclusiveOR and exclusiveNOR, I did so because "Mu" could never possibly
be reduced to a verifiable proposition regardless of how many negations
it contained. Any such expression would require both the Law of the
Excluded Middle and the Law of Contradiction. If we succeeded at that,
we would fail, because the resultant statement would have to be either
true or false, another "discrimination" forbidden by Buddhism of any kind.
Do you suppose we have come up with a genuine Koan without a Roshi
to clap us both about the ears?
Take care,
Bob
