That said, the vast majority of those papers probably have to have some kind of IRB (or equivalent) oversight, particularly if they involve human or animal subjects.
These review boards have to make a determination on whether or not the research methods are ethical, and ethics is indeed a branch of philosophy.
If you look at the quote that you took from my post, I specifically said “core” science, and I've stressed that core all the way through, and distinguished it from softer areas of science or more fringe use of science. All research papers in core science have to pass peer review before publication (many papers are rejected outright … and many more are required by the reviewers and the editors to be changed with corrections and omissions and additions etc.). But those papers are not about the treatment of animals (or humans). However, even where branches of science (eg medicine) do conduct research on human and animal issues, it is not afaik the job of the journals review body to decide if the work has been conducted in a “ethical” way … that would be done long before the stage of publication, where the work would be required to follow all existing rules and laws about how animals (and people) are to be treated.
None of that needs academic philosophers who have specialised in what philosophy calls “ethics”. The courts and governments (and the scientists who work in those fields) do not summon phlosophers to tell them what is or is not ethical, ie humane etc., treatemnt of animals or people. They are perfectly capable of deciding that for themselves without having to be bodgged down with literaly endless diatribes from philosophers. The philosophers input is not helpful, and it's not required.
Additionally, as lomiller says, science uses the scientific method, which is epistemology - a branch of philosophy.
Sorry, but that is simply absurd. What is called “epistemology” in philosophy, is afaik a study of “knowledge” and how we “know” things. The so-called “scientific method” is just a set of general procedures which people (scientists) have found to be very productive as a way of investigating and explaining the world around us (roughly what we think of as all of “Reality”). You are trying to give philosophy the credit for whatever scientists discover and explain, by claiming that just because the scientists have tried to understand the objects and events in the sense of accurately explaining all of their properties, that must mean they were actually doing “philosophy” simply because they were increasing our “knowledge” about all of those things.
That's just another way of trying to say that everything is “philosophy” … so that whenever anyone thinks about anything at all, and tries therefore to “know” something about it, it must be credited to “Philosophy”.
Similarly, the data and results have to be interpreted. As you say, science doesn't speak, so scientists have to make the most logical derivations of the data, and discount any fallacious reasoning that they might be tempted to make. Logic is indeed a branch of philosophy.
This is again trying to say that everything is philosophy. You are trying to give the academic subject called “philosophy” the credit for whatever science (or mathematicians!) think of whenever they try to use their brain to decide what is likely to be the explanation for anything.
On that basis all thinking animals are also philosophers conducting philosophy all of the time 24/7.
Philosophy is a much older subject (much older than what we now describe as “science”, and older than what we now describe as “maths”). It goes back further even than the time of Greco-Roman philosophers of around 500BC. Philosophers were just the academic thinkers of the time. They tried to think of how the world could be explained. That lead some of them to use early forms of what much later became a scientific method. And still more of those philosophising individuals had used numbers and the manipulation of numbers, which increased over the centuries with different philosophers and which was clearly the beginnings of what we now have as the modern subject of “Mathematics” …
… nobody is denying that philosophers had started to think about all such things many thousands of years ago. But that does not make everyone today who thinks about such aspects of the world, a “Philosopher”. What happened in the case of science is that around the time of Galileo, a new way of attempting to investigate the natural world began to emerge. That was largely because by that time new mechanical devices had been developed, such as the telescope and the pendulum, which some philosophers of the time (such as Galileo) realised could be used to make actual measurements and to record actual numerical data from objects such as the stars in the night sky.
But that turned out to be a very fundamental change from what had been the earlier method called “philosophy”. Until then what philosophers had done, and what some of them still do even now, was to try to find explanations for the natural world, by pure thought of intellectual reasoning alone. However, what was gradually realised with the new methods of using instrumental measurements, was that it's actually virtually impossible to properly & accurately understand the world around us just by philosophical reasoning alone. That was where science succeeded in a way that earlier philosophy had failed to do. And the difference has turned out to be enormous – it showed that philosophical thinking alone is virtually useless when it comes to genuinely explaining the nature of “reality” in the universe around us; whereas in vast contrast that newer emerging method called “science” has turned out to be so good at explaining things that it's ability and it's success has been “proven” beyond even anyones wildest dreams … really what happened, was that science eventually exposed the weakness of philosophy (where, historically, for much of what was done under the title of philosophy, it has turned out to be little better than religious belief).
That's why today science and mathematics are two completely separate and distinct subjects, and not part of philosophy. If you go to a university to study (say) physics or maths, then you will not be in a section of the philosophy department, and you will not be given philosophy books which might have a couple of chapters about “mathematics” or about the history of “physics” … they are today properly regarded and established as completely different subjects from one-another. That's why science is called “science” ; it's why it's not called “philosophical science” … it's long since become a separate and very different subject.
Perhaps the branch of philosophy that gets the worst rap is metaphysics, and it is here that people who call themselves "philosophers" (random people on the internet usually, or gurus). That said, I think that I became an atheist through reason and realizing that the claims of religion are incoherent. This is a form of metaphysical reasoning, and I did that before I knew much about science. In that sense then, even metaphysics is useful.
I'm really not interested in philosophical terms like “metaphysics”. But afaik, that is supposed to be the study of all things that exist as a “reality” in this universe. But you did not need an academic course in philosophy of “metaphysics” to teach you how to think for yourself about which claims and beliefs are credible or reasonable. You could, and no doubt did, determine that for yourself without being taught it from a philosophy book. If you want to understand what appears to exist as “reality” in this universe, and you want to understand what you can discover about that, then as I said before – science has proved enormously successful at that, far far beyond anyones wildest imagination/dreams … whereas philosophy has proved virtually 100% useless for studying, investigating and explaining the universe around us.
Really what you are doing again, is trying always to give the subject called “philosophy” the credit for any sort of thinking that you or anyone else ever does.
