I want to try to make this as interesting as possible
So there are a couple subtleties going on here that I want to comment on, in case it helps both of you address each other!
First, what Ren probably is getting at is the idea that maybe GIVEN you are aiming to do science, there are certain oughts you must follow, but what if nobody said you ought to do science in the first place, or do anything for that matter. At least that's in my own gloss on what I think he's saying.
However, here's where it gets interesting: what if I ask why someone ought to follow certain protocols in order to do good science?
The direction I see Ren's post going is you'd say
well that's the definition of science!!! Maybe that isn't the direction it's going, but it certainly seems very natural/common to take it that direction.
The subtlety I see here is what if we don't make that leap of defining science as following the scientific method/etc, and instead say the aim of science is to discover the truth of the physical world? THEN, the real question is are there right and wrong answers as to how to get at that truth. How do we come up with the elaborate methods we use today?
The strongest version of what I'd (possibly mistakenly) think is wolly's point is simply that, if the methods we actually use to arrive at physical truth are themselves merely subjectively better than other methods, then it basically seems like science is just a game we play, not describing an independent external reality.
And this is especially salient given the example Ren gave as an analogy WAS A GAME (what with the scoring goals!), where we have infinite discretion to come up with the rules, vs if we're describing physical truth, and think it corresponds to objective reality, we can't call it at our discretion in entiretly, presumably!
If we're coming up with the 'oughts' needed to do science, aka discover physical truth, we can't call those oughts themselves science, so wolly might surmise they're philosophical oughts, which not unreasonably may be called moral oughts.
However, to bounce back to Ren's point, I'd wonder what if we're asking the more basic question: are there any oughts at all?! That is, ought I be rational? Ought I be scientific?
Certainly if I ought to be anything, it is be rational, as there doesn't seem any grounding for any other ought if you're willing to accept contradictions.
But there's still that beginning "IF" ..
