...much later... The thing that puzzles me about this post is that no attention is paid to context.

I had an operation last year to my right index finger. It was carried out by a hand surgeon. I used those terms because it was rather important which finger was operated on, and because the medical specialism relates to any part of the hand indifferently.

A trivial example, of course, but it illustrates the point, which applies also to much more complex issues, that the appropriate choice of "model level" (or other meta-model feature) to best represent the aspect of reality that matters depends on the context (and especially on the purpose). The difficulty begins, IMHO, when people insist on using the same model or meta-model whatever the context.

Most commenters on this post seem entirely wrapped up in the mind/brain question. That isn't the only question for rationalists to have a view about! They don't seem to be aware that arguments about the usefulness and limits of reductionism also continue in many other fields. The problem is probably that concepts like emergence are used in the mind-brain debate as an excuse for vitalism. But that is really a special case, just because minds are the things that are conducting this debate. In other fields emergence can be a useful concept. In other words I can claim that emergence is useful (in some senses anyway) without believing this has anything to do with consciousness.
