I'm not sure I understand your assertions. Philosophy requires points of view. Ignoring the dubious ability to do the same to the result of any measurement, the fundamental problem with philosophy is that it requires a point of view, and therefore an unquestionable axiom.
Is it right or wrong to kill one hundred humans? The answer wholly depends on what point of view you take. Statesmen have used that throughout history to justify everything.
I shall take some choice quotes from the paper I linked. As is the danger with this practice, I quote to bolster my argument .. a full perusal really is necessary.
"Philosophy is essentially destructive. Whatever you believe, no matter how obvious or fundamental, no matter who you are, or where, or when, there's a good philosophical argument that your belief is false. There is no deep, foundational belief that philosophy cannot refute (not even Descartes' Cogito)."
There are some major problems with this concept.
First, as the quote I left in there says, no matter what your belief is there is a good philosophical argument that will refute it. These ideas about philosophy being inherently destructive and unable to progress are, in fact, philosophical beliefs. By this philosophy's own declarations, this philosophy can also be undermined by other philosophy. Ironically, this belief that talks about how destructive philosophy is might just be the most destructive of all philosophical beliefs, because it essentially says that the field as a whole is worthless,
including itself. All one would need to do to refute this claim of zero progress would be to find a time when philosophy made significant progress. Funnily enough, another one of your quotes does just this by citing "Mill's on women's rights, for example; Locke on individual liberty and equal rights" as philosophical works that were at the forefront of the development of modern ethics. Look at that, progress was made, this philosophical belief has been refuted by its own assertions.
Another problem is that this school of thought indirectly claims that all philosophy is equal. For there to be a "good" philosophical argument to refute every belief, by necessity all philosophical arguments must hold equal weight; before anyone goes calling straw man on me, I challenge you to come up with some alternative way all philosophical thoughts could have good arguments for refutation other than this total equality of philosophy that I speak of. You cannot refute Mill's ideas of women's rights without saying that a philosophy that posits that women are no more than chattel is of equal worth and weight, so they must of course be considered equal due to this philosophical belief of inevitable refutation. A philosophy espousing world peace would have to be totally equal to a philosophy calling for the willing self-extinction of humanity. Nazi philosophy would have to be totally equal to Gandhi's philosophy. If all philosophies are not considered wholly equal then the infinite refutation would not be possible, thus by necessity if you believe in the idea that philosophy is inherently destructive and everything can be refuted you have to set each idea as perfectly equal to all others. Furthermore, to make this work you would actually have to say that refuting a philosophy does not make it totally worthless until you're done using it to refute other philosophies, else the system falls apart. You have to be able to refute philosophy A with philosophy B, then refute philosophy B with philosophy C but go on to say philosophy B is
still completely valid for refuting philosophy A because otherwise you would end up with a relatively small set of master philosophies that cannot be refuted. Some would say this illogical requirement disproves the whole philosophical belief, but luckily logic is a philosophical concept that by this theory is apparently easily refuted, so all is well. I hope I don't need another paragraph to explain why this sort of total equality just doesn't ever work in the human mind, thus making this philosophy actually kind of impossible to ever apply practically.
Actually, for the hell of it, let's see where blunt force application of this infinite refutation thing would lead someone if they believed in it and followed it. I think it would have to lead to the death of one's humanity. All systems of morality are easily refuted, thus you cannot have morals. All thoughts of property rights are easily refuted, thus you cannot own anything and you cannot respect what others claim to own. All philosophies of certain things (like rape and murder) being bad or wrong and deserving of punishment are easily refuted, thus you cannot condemn anyone for even the most heinous of atrocities and punishing them is totally out of the picture. So on and so forth, once you strip all philosophy away because none of it is true due to all of it being easily refuted you're left just with pure instinct and biological necessities to run your actions. This is the only way this philosophy can go if you actually believe in it and follow its principles. To hold to a moral code or respect property rights or want to punish murderers would be to follow a philosophical belief that you know is utterly and completely worthless, so a true believer in the limitless refutation wouldn't be able to follow any of them. Abandoning all higher thought is alright because you don't really exist (because Descartes is refuted) and the physical world is just a dream (because the ideas that the physical world exist and our senses are reliable are refuted; by the way, this means all of science is false) and there would be no consequences if you behave like an animal (because cause and effect as a concept is refuted). Shit, maybe I didn't go far enough. Maybe the end game of following this philosophy is not a mindless animal state, but rather a coma state where you just lay there and do nothing because nothing is real and you don't exist. This is the kind of nonsense that you get if you try to apply this philosophical concept of total refutation in any practical way, which I think is a good philosophical argument to refute its validity.
Back to basics, another problem here is that "there is no progress in philosophy" defeats itself in yet another way, this one more direct. Progress in this context would be new or improved ideas. There would have to be no forward momentum, no new philosophical concepts coming into existence, for this to hold true. However, "there is no progress in philosophy" is a philosophical concept that at one point in time was a new idea. Positing that there is no progress is in fact taking a step forward and making progress in philosophy. It's a self-defeating concept. It hasn't always existed, thus it was new at some point, thus it was progress, thus it is wrong.
However, with all of that said, I think the biggest problem with the idea of there being no progress in philosophy is that it misunderstands what philosophy truly is and points only at science as "proof" that there is no progress. Philosophy in fact lies on the middle of a spectrum rather than standing hand in hand with science alone. The two ends of this spectrum are science and art, and philosophy is roughly equal parts both of them. Philosophy compiles new information in the same way as science, and a lot of the new information is thanks to scientific advances, but it does not do the same things with new data as science does. Science stacks new data up in a very orderly fashion to build towers to reach new heights of understanding. Philosophy instead uses the methodology of art in this regard: instead of building towers, it lets everything pile up in a few disorganized heaps and digs through them at leisure. To understand what I mean by this, think of classical music and modern pop music. Can you say without a shadow of a doubt that the modern music is better than the classical? Do the same with styles of painting. Do the same with styles of writing. You may have preferences, but saying one is inherently superior to the other would be foolish. It's rather similar in philosophy.
In philosophy, as it is in art, there is no massive strive for improvement. You get some new things that pop up once in a while (like new musical genres), and some new takes on old ideas (like new musical subgenres), but it's hard to say one is objectively better than any other. It can be done if you choose a particular set of rigid metrics and apply it to all of the different ideas, but who's to say that your choice of metrics is truly objective? Instead it's more a matter of personal preference. Some people will think a particular philosophy is the best and others will disagree with them, and that's fine because it's a subjective thing. Some societies will generally discard whole areas of philosophy (such as moral philosophies which say there is no such thing as right or wrong so no punishment is justified) just as they will largely ignore certain types of music (such as how polka is pretty rare in the United States). It's just the nature of the beast.
Philosophy has never been a pursuit of objective truth; philosophers are quite aware that there can be no objective truth from thoughts alone. Progress in philosophy cannot be fairly equated to progress in science because they have vastly different methods of gathering and using information, which means their benchmarks for progress are different. Progress in science is the discovery of objectively verifiable new things, the clarification of points of old things, and disproving things previously held to be true. Progress in philosophy is the accumulation of new things and additions to old things; the nature of these additions actually doesn't matter, because new things go into the piles whether they're great truths or fallacious nonsense. Philosophical progress is not just about coming up with utterly new things, just as scientific progress is not just about totally new discoveries. Science deals in facts and certainty, philosophy deals in concepts and probability; they are different entities, thus it is ridiculous to apply the same standard to both of them. To claim that philosophy makes no progress you have to completely mistake the nature of philosophy and totally ignore the past couple thousand years of new ideas and additions that have been made. Just because it does not reach toward the same lofty goal of objective truths that science aims for does not mean that there is no progress. That is the main failing of "there is no progress in philosophy," and that alone is enough to discard the idea as false.
