I moved the big meta-level comment thread from "Yes Requires the Possibility of No" over to here, since it seemed mostly unrelated to that top-level post. This not being on frontpage also makes it easier for people to just directly discuss the moderation and meta-level norms.
Abstractions are a central example of things considered on the object level, so I don't understand them as being in opposition to the object level. They can be in opposition to more concrete ideas, those closer to experience, but not to being considered on object level.
