[MD] What does Pirsig mean by metaphysics?

[ARLO J BENSINGER JR]

[Platt]
It's extremely incoherent to assert as true that truth is relative.

[Arlo]
"All this is just an analogy." Pirsig got it. Why is this something you
struggle with year in and year out?

"Of course it’s an analogy. Everything is an analogy." (ZMM)

"Phædrus has caught it and remembered it, because if Socrates hadn’t stated
it he wouldn’t have been telling the "Truth."" (ZMM)

Exactly. 

Last time we were through this I told you my young daughter can see through
these sophomoric word games. I had hoped the next time this came up, you might
show some signs of learning. The definition of "insanity", I suppose.
