I'd really like to know what you mean here in both of your possibilities. Why would you think that an option is that laws of nature are quasi-theological? The regularities are true propositions about the world. I'm not understanding where theology comes into play. By quoting "laws of nature", did you mean to imply that an option is that we are governed by some supernatural force?
On page 84 of this thread, in response to your question "What are laws of nature?", Night Ripper stated:
"Most people mean laws in the necessitarian sense, that they are magical rules the universe must obey, must conform itself to. That's theology in disguise."
Like you, I reject supernatural explanations. So what else could "laws of nature" mean?
One view seems to be that they refer to the regularities in the universe which (according to this view)
look as if they are "governed" by something (whatever that may be) but are actually "lucky coincidences" of purely random events. On this view, absolutely anything that is logically possible could happen at any time; the force of the Earth's gravity could suddenly double for no reason, or iron could turn into gold, or the tree outside my house could uproot itself and shoot 100 feet into the air. Strangely, those who hold this view do not expect that any such things will actually happen; they predict that the same old regularities will continue to happen by pure chance. On the grounds of (a) its statistical improbability and (b) its inability to justify induction, I consider this "accidental regularity" view of laws of nature to be just as fantastical as any supernatural explanation.
Is there any other alternative? Can we explain the laws of nature (i.e. the observed regularities of the universe) in a way that rejects both supernatural agency and randomness? Can we give a physical, rather than a metaphysical, explanation which does not require outrageous coincidences, and which justifies the use of induction to predict the future? That is to say, some kind of "physical necessity" (as opposed to logical necessity).
Night Ripper's sentence "There could be no other possible universe where the regularities didn't occur" is close to what I am suggesting. However, other possible universes might have different initial conditions from ours, which would result in different causal chains of subsequent events. So I would prefer to say something like "There could be no other possible universe where the (same) regularities didn't occur
given the same initial conditions".
