I've read some of the metaethics sequence. Is there some particular part of the metaethics sequence that I should focus on that addresses the conceptual integrity of something like "the Good" in a clear and direct manner with logically arranged evidence?

When I read "Three Worlds Collide" about two months ago, my reaction was mixed. Assuming a relatively non-ironic reading I thought that bits of it were gloriously funny and clever and that it was quite brilliant as far as science fiction goes. However, the story did not function for me as a clear "deconstruction" of any particular moral theory unless I read it with a level of irony that is likely to be highly nonstandard, and even then I'm not sure which moral theory it is suppose to deconstruct.

The moral theory it seemed to me to most clearly deconstruct (assuming an omniscient author who loves irony) was "internet-based purity-obsessed rationalist virtue ethics" because (especially in light of the cosmology/technology and what that implied about the energy budget and strategy for galactic colonization and warfare) it seemed to me that the human crew of that ship turned out to be "sociopathic vermin" whose threat to untold joules of un-utilized wisdom and happiness was a way more pressing priority than the mission of mercy to marginally uplift the already fundamentally enlightened Babyeaters.
