Like I said, RM&NS is kind of axiomatic in my thinking. To question it seems
almost like David Hume's questioning of cause and effect, his claim that all we
can see is conjunction of events, that the idea of causality between them is
metaphysics. Well, RM&NS isn't quite that abstract, but it is a principle of
great generality; I don't see any competitor to it in terms of explanatory
power.
