My response to this situation depends on how he’s getting money for drugs given that he no longer has a job and also on how much of a hassle it is for you to give him couch-space. If you don’t have the right to run his life, he doesn’t have the right to interfere in yours (by taking up your couch, asking you for drug money, etc.).
I am deeply uncomfortable with the drug-cocktail-personalities-as-separate-people approach; it seems too easily hackable to be a good foundation for a moral theory. It’s susceptible to a variant of the utility monster, namely a person who takes a huge variety of drug cocktails and consequently has a huge collection of separate people in his head. A potentially more realistic variant of this strategy might be to start a cult and to claim moral weight for your cult’s preferences once it grows large enough…
(Not that I have any particular cult in mind while saying this. Hail Xenu.)
Edit: I suppose your actual question is how the content of this post is relevant to answering such questions. I don’t think it is, directly. Based on the subsequent post about nonstandard models of Peano arithmetic, I think Eliezer is suggesting an analogy between the question of what is true about the natural numbers and the question of what is moral. To address either question one first has to logically pinpoint “the natural numbers” and “morality” respectively, and this post is about doing the latter. Then one has to prove statements about the things that have been logically pointed to, which is a difficult and separate question, but at least an unambiguously meaningful one once the logical pinpointing has taken place.
