Disclaimer: we still have pragmatic reason to follow the evidence suggested by our best scientific theories. I'm just poking fun at scientists in the spirit of Hume. There's no guarantee that the future will resemble the past, and even our best scientific theories are amenable to future evidence.
Both Newtonian and Einstein’s physics suggest a boulder pushed off a cliff will fall, as far as I know. The observable data is more intrinsically valuable than the theories using them.
Fallibility isn’t something science shies away from. There’s nothing more exciting in the scientific community than when science is wrong about something.
Philosophers grandiosely proclaiming that nothing is knowable is fine, but it’s not what put a man on the moon.
We aren't even disagreeing now but you would rather argue than grasp the point. Point being, the presuppositions of science are not themselves within the purview of science. All our best theories start with axioms.
You continue to talk about the usefulness of science, which I conceded before you ever typed your first comment. At this stage, I have to assume that you're being willfully obtuse.
You said you were poking fun, I poked back. I appreciate the conversation, I enjoy thinking about these things.
