This comment was sitting at -2 when I saw it, which makes me think that maybe I don't understand Eliezer's point. I thought the OP was making the point that when we talk about something being "attractive" or "moral" or maybe even "sapient", we project facts about our minds into the real world. "Attractive" really means "attractive to humans", and if we forget this fact, we can end up inadvertently drawing wrong conclusions about the world. If that's wrong, then what was this post actually about?
