Great points, this forum has always had camps of users, some are willing to discuss and others just to argue. It seems more exaggerated on this sub-fora than others.
If what I am writing comes across as arguing merely for the sake of it, and not as if I am willing/trying to discuss what any of us thinks, believes or claims, then I have to apologise for giving entirely the wrong impression (or else somehow, some people have apparently got the wrong impression for some other reason).
What I am saying as a general overall comment on philosophy as a formal academic subject, and specifically here when people present claims such as Solipsism and the idea that perhaps no reality exists outside of our minds, is that I do not think that philosophical idea holds up to any scrutiny ... and I think it also does not agree with what we can detect as "evidence".
But on the wider point - afaik, it's true that from ancient times philosophers thought they were discovering true answers about the way the world around us worked. And they were doing that mostly by relying upon pure intellect and what seemed to them to be logical argument. That seemed fine until about 1600 AD when Galileo and others began to realise that the reason why the answers given by both philosophy and religion were all turning out to be wrong, was precisely because they were relying on the belief that the universe could be entirely understood merely by thinking about it and deciding what seemed logical.
At first sight that idea of logical thinking probably seemed an inescapable truth. What else could anyone do? How could you ever do better than that? Well, from the first beginnings of what we now call modern science (e.g. starting approx. 1600-1700), what became increasingly apparent was that that supposed logical thinking always contained all sorts of personal bias and habitual long-time erroneous beliefs. And what changed that was the realisation that we needed to take actual measurements of things, to make real physical observations, and use real mathematical calculations...
... still that method was not infallible (for all sorts of reasons), and true it did require certain new inventions such as the pendulum and the telescope, which were not available to ancient philosophers ... but it was only from that time onwards, with the use of that scientific approach, that we started to find answers which were quite different to those proposed throughout most of earlier philosophy, and of course very different to what religion had always taught as the truth. And they were also answers which could be tested, checked, and shown to be as close to "correct" (i.e. "true fact") as anyone could reasonably demand within the limits of instrumentation and methods of the time.
And the point of saying that, is that the success of science has really killed philosophy (and religious belief) as a credible way of claiming to understand the world around us. So that - if any of us wants a credible answer to any questions about anything in the universe around us, inc. questions about humans, the way humans think and what processes that involves (it requires a physically existing organ called a "brain" etc.), then the only credible way of deciding the most reliable answers to any of that is science, and not philosophy or religion.
I am saying that science has really killed off philosophy (and religion) as claimed ways of telling us what the world around us is really like. And as an example that I've used here before - that's why in advanced democratic societies the courts have come to rely increasingly on scientific expert witness evidence, and why neither defence or prosecution lawyers are ever again likely to call either priests or philosophers to persuade a judge and jury. And that was not always the case. On the contrary, in the more distant past afaik it was very often the case that a court would rely on religious witnesses to convince a jury or convince the judges, and I expect they also often called philosophers to advise the court on what was believed to be right vs. wrong .... but that is not the case any more ... instead what is the case is that a legal ruling for what we should accept as right vs. wrong relies more-&-more on the evidence of science ... and the reason for that (to repeat) is that science has more than proved its' credentials, and in doing so, it has unintentionally removed virtually all the credentials once claimed by philosophers and theists.
What has that to do with the subject in this thread? Well I hope the answer is obvious and inescapable. But if not - the answer is that science has proved itself hugely more believable and credible than philosophy when comes to any question such as whether or not scientists are right to regard what they detect and explain about the world around as "real" ... and by the way, it is certainly not credible to argue that scientists do not really believe that they are detecting real things and describing those things accurately ... they do "all" believe that the evidence and the established Theories are completely consistent with what we know as "reality" (and I only put "all" in quotes to emphasise that with perhaps 10 million scientists in the world, it's inevitable that some of them will say almost anything, including even the most absurd and nutty things ... but the vast majority of scientists in the relevant expert fields of core physics, most parts of chemistry and maths, and large parts of biology, do agree that they are detecting and explaining "reality").
