Right on target, I'm working on a paper on reflective equilibrium, and one of my claims will be nobody really "does" RE. Our moral world is norm-centric, not theory-centric. When was the last time you used moral theory against the jerk who butt in line in front of you?
Instead, I claim that what we think of as reflective equilibrium is really just a mirroring of the academic social world: professors and students kicking around moral intuitions and theory's, and the discussion ends when some kind of understanding of all the concepts has sufficiently formed.
The issue of justificatory force for theory is thus irrelevant as it represents a category error.
(Sorry I don't know how to connect this to Arthur's post.)
