How do we know "all that exists"?
Pirsig describes the experience of reality as DQ/SQ, indefinable/definable
reality.
I conceptualize a manifestation of the differences in species, as evolution,
a manifestation of levels in existence.
Indefinable DQ is individual perception. Definable SQ is evolved conception,
the individual in its origin.
How we know follows metaphysics. SOM suggests we know by abstraction.
IMHO MOQ accepts the direct experience of evolving/evolved reality DQ/SQ.
Metaphysics describes levels of existence in indefinable DQ/definable SQ
individuality.
