I'd agree with the above - "Does anything exist?" isn't a worthy scientific question, and it's not even a worthy philosophical question - note the question got zero traction in this thread.
'Naive realism' (objects are what thy appear, or close to as they appear) or some varient of 'realism' is the dominant 'philosophy' of our culture - and of the folks in this thread. Because it is the dominant paradigm, it doesn't feel like 'doing philosophy' to believe it or endorse it - it doesn't even feel like a belief - as it is the norm and rarely challenged.
My point has not been whether endorsing 'realism' is doing philosophy or not, my point is that 'realism' is a belief, and at least to this point in time, this belief has not been demonstrated by science to be true or false.
Nor is believing in 'realism' necessary to doing science.
Perhaps in the future, beieng a realist may hinder one's ability to do good/great science - time will tell. Beliefs have a tendency to become a problem eventually.
Maybe, but what I've seen so far is more like fighting one's own strawmen from most of "science is like religion" bullcrap peddlers either. I don't even call that the position of
philosophy, because philosophy doesn't deserve to all be tarred with that crap brush. It's more like what intellectual zeroes without a border do when they try to pretend they're philosophers.
And while I'll disagree with Joe's or Ian's position that all philosophy is BS peddling... it's not hard to see where he's getting that impression from. If everyone trying to convince you of the merits of some domain X -- let's call it xnorgology -- is just chasing strawmen and trivial/irrelevant platitudes, you too might be excused for forming the impression that it's just a scam.
Anyway...
For a start almost nobody actually proposes
naive realism, and it most certainly isn't the position of
science. It's a
psychological condition, more than anything even resembling science.
In fact from quantum physics, to GR, to neuroscience, to middle-school level science class, almost every scientist will tell you that no, what reaches your retina isn't the absolute, definitive, unaltered representation of reality. Trivial school-level example: due to refraction in the atmosphere, when you SEE the sun touching the horizon, it actually already is below the horizon if you drew a straight line in space between your eyes and the sun. Even more trivial example that even a kid should be able to understand if they know anything about computers: just because
you see this text as purple, doesn't mean it's in the (non-existent) wavelength of purple. Even more trivial example for anyone who's even vaguely aware of dogs: just because you can't hear a dog whistle, doesn't mean it actually doesn't make a sound. Etc.
In any of the above examples, believing that whatever your eyes and ears perceive is THE unaltered, exact, indisputable reality is a delusion in psychiatry, not something that the proponents of science actually propose.
So arguing against the naive realism idea is just fighting one's own idiotic strawmen, rather than actually showing any actual problem with science.
I also notice that the more relevant ideas that pop up in such threads are invariably ignored, in favour of chasing such strawmen or doing trivial navel-gazing. Good philosophy, it ain't.
E.g., I didn't see the idea of context being relevant -- I think it was Myriad who posted it -- being addressed, or at least not in any meaningful way. E.g., I don't see any addressing the idea I've posted in more than one thread, namely that
it doesn't actually matter for any practical purposes (including scientific) exactly how really real reality is, as long as it changes absolutely nothing, as in, no prediction or experiment will ever turn up any different, and thus is 100% untestable.
