Are you really so certain that good is measurable? Or that good even exists? Good vs. bad is but the tip of the moral iceberg; we are not merely concerned with whether our actions will please some deity trapped on a cosmic battleground, but the precise nature of what our actions will effect in the world. To pop out and flip around an old Christian argument, your position is like saying that color photography misses the fundamental problem of determining what a given shot would have looked like in greyscale; it's like asking somebody who sees full color to explain each different color to somebody who only sees black and white. I could say that each color is kind of like white and kind of like black, but really it's more like a mix of both, but really it's not like either at all. And once we stop saying "good" or "bad", and start saying instead quantifiable measurements, like "number of meals prepared" or "number of houses built", then we see that there's a little good and a little bad in everything. Pirsig had a way around most of this, but even he still talked of "good" as something that one person measures/evaluates/observes in another person, and we might interrogate him by asking, "What about that person is good?" to which he might have replied, "I see a certain thing about them, and I perceive this thing to be good."
