Mark, I apologise if I have given you the impression that i believe there is a "special class of explanation which fails to supply an account of the relationship between things"
I don't think I've ever said or infered that. My argument comes from the fact that your definition precludes an explanation from covering the origin of something/everything.
Obviously, as I believe you pointed out this discussion is based around an infinite regress of cause and effect, back to the intial cause. So as has been the case (In plate tectonic theory for example) the advancement of scientific technique and knowledge creates more explanations, based on the relationships between observed phonomena which explain their origin ... surley you can see that if the relationships between all matter (i.e. the universe) where defined ... then it's origind would be described in those relationships?
