This is an interesting question and I am not quite sure what you mean.
So far as I can see, MoQ is a description of Quality in metaphysical
terms. Personally I would not say it is self-evaluation. However, I
think it can be considered an evaluation of existence. For me, MoQ
describes a certain manner of looking at reality. As such, It
provides a basis for this evaluation based on the Quality which Pirsig
speaks of in his books. One way to look at it is that it tries to
bring understanding to What Is in a manner which relies much on
personal interaction. It tries to bring in a distinction between "the
way we are told it is", and "the way we feel it is". This is why we
cannot be told what is good and what is bad. We just know these
things. Just my humble opinion on MoQ.
In my understanding, self-evaluation is a static projection. Such
self-evaluation relies heavily on the social level, and can only be
done in relative terms. That is, we objectify ourselves and compare
ourselves to another. I could even speculate that MoQ draws a
distinction between the biological level and both the social levels.
If I were to expound on this, I could say that the social and
intellectual levels rely heavily on static quality whereas the
biological level (which I like to call the "personal level") does not.
It is much easier to follow DQ (as it were) free from the constraints
of the intellect and social pressures. As such, both the social and
intellectual levels are static-based, whereas the biological and
inorganic are dynamic-based.
Of course both static and dynamic quality make up our existence. My
point has always been that this duality is out of balance. The static
is so dominating that we forget about the dynamic that makes up our
existence. We become robots following what we are told is the way it
is. Pirsig saw a whole different world when in Chicago. He is trying
to tell us what he saw. ZAMM resonated with many people and they saw
it as useful. Lila is useful too if one spends the time trying to
figure out what Pirsig is saying from a personal point of view. The
words and examples can be distracting, but so long as we keep in mind
that Quality overrides truth, then we are OK. At least I am OK.
Don't know if this answered your question.
ps: the tricky words was just a rephrasing of what MRB had written about Zen.
