That of course stands as overwhelmingly shown in that thread. 3 minutes ago, Davy_Jones said: If this is the case, how can our knowledge of the universe be increasing? How can you say that as science gains knowledge it is falseifying the fact that science does not necessarily describe reality? You have lost me. In actual fact though, what I did say was that the object of scientific theories and models, was not this undedfined truth and/or reality you seem so fixated with, but that if by chance that should be discovered or realized, accidently or otherwise, then all well and good. But hey! we have a thread on that if you want to keep philosophising on that matter.

TheVat Posted September 7, 2021 Posted September 7, 2021 1 hour ago, Davy_Jones said: Personally, I see it as regrettable that certain scientists are not only ignorant of, but hostile to, philosophy. I think of it as the timid, bashing a strawman. Part of this arises from viewing philosophy as a unitary academic field rather than an array of subjects that range from austere metascience* and ontology to more worldly ethics and political philosophy. And linguistic philosophy, too. Every field can benefit from a meta-discipline that steps outside of the field and considers it's methods, scope, aspirations, symbolic systems, and epistemic stance. As others note here, many fine scientists have engaged in meta reflections, whether they called it that or not. And I can think of very few physicists who have never engaged in a little epistemology as regards the inferences they can make from many indirect sorts of observations. *(when I use the term "metascience, " I'm trying to show the contours of something a little more than metaphysics -- it's all that is "meta," which includes epistemology and, in fields like cosmology, some ontology as well) 1

That is to say, and continuing with BIRD as our example, people do not treat all birds as equally bird-like. A sparrow, say, rates far more highly as a respectable card-carrying BIRD than does an cassowary, say. Moreover, subjects will assent far more quickly to a sparrow being granted BIRD status than an ostrich or a turkey. A cassowary, it would appear, is indeed a BIRD, just not a very good one. Not a very good one? If that was the case, I suggest they may be extinct by now. The Emu is another...different types of birds, those that fly, those that don't those that hunt, those that don't....

"Good" here means conceptually more bird-like than other birds. It does not refer to survivability. Edit: I have little doubt the same holds for our concept SCIENCE, even though we routinely see attempts to encapsulate the essence of science in a definition. For example, show a group of people two pictures: One of a dude collecting bugs; The other of a slightly mad-looking dude with unkempt hair in a white labcoat mixing dangerous-looking chemicals together My money's on the subjects identifying the latter as doing science more quickly. They'd probably take a bit longer with that poor beetle collector, assuming he's even granted scientist status at all. Edited September 7, 2021 by Davy_Jones

TheVat Posted September 7, 2021 Posted September 7, 2021 It may be worth noting that, logically, to know that one is getting closer to the truth requires knowing where that truth resides. If you approach something whose location is unknown, then you only do so by accident. There is certainly the feeling that one is closing in on the truth, but that's a feeling resting on a web of beliefs, about what all those pretty, regular patterns we observe mean. Our beliefs about what constitutes genuine knowledge need constant inspection, which is where the tools of philosophy are handy. 1

We have an estimated age along with stated error bars, based on current knowledge and data. Like most scientific models/theories, they may change in the future. That's science, that's the scientific method. A shame you seem so intent on ignoring that.
Davy_Jones Posted September 7, 2021 Posted September 7, 2021 It's a logical point, beecee. It makes sense, on a road trip, say, to state "We're getting closer to Adelaide" . . . because the exact location of Adelaide is already known. It makes far less sense to say "We're getting closer to X even though no one knows where X is".

Of course we don't in many cases know where the truth/reality [if it exists] lies.

The point is, in context, and as discussed in the gravity thread...Scientific theories and models, are not out to determine X, if X even exists. But as VAT also says, we may still reach it [X] accidently. Our models only need to be useful and predict successfully as Newtonian mechanics and GR already do. Edited September 7, 2021 by beecee

And I'd reiterate, this is almost certainly a minority view in science as a whole (physics being the apparent exception). Try asking a psychologist if he thinks consciousness is real. Try asking a geologist if she thinks tectonic plates are real. Try asking a paleontologist if he thinks dinosaurs are real. Try asking a chemist if she thinks oxygen is real. Try asking a neuroscientist if she thinks neurons are real. Try asking Richard Dawkins whether he thinks natural selection is real or merely a theoretical postulate, useful for predictive purposes, but not to be taken at face value. . . .

No one has ever said it applies exclusively!!! And to answer the last one first, we know the theory of evolution is fact...no scientist worth his salt denies that...most lay people see it as fact also. Scientists know Abiogeneis is fact, despite not yet knowing the exact pathway or methodology. [1] Dunno [2]true. [3] True [4] True [5] True So well done for your well thought examples, although it does nothing to invalidate exactly what I have said. 🙄 Now I believe this is off topic, so raise your points in the gravity thread, where it appears against all the evidence so far and expert comments, you still have doubts...or an agenda.

beecee Posted September 7, 2021 Posted September 7, 2021 (edited) Another point I will make, is that in this day and age, at least in my opinion, philosophy is more closely tied with religion then science.......science is undoubtedly the ultimate tool for understanding the physical universe around us, from the largest stars and galaxies, to the extreme distances of the observable universe, down to the realm of quantum/Planck interactions. Religion on the other hand inherits the uncertainty of faith and the unanswerable philosophical questions that then arise. Another similarity with religion/religious people. as distinct from science and the scientific method and theories, is that the questions both ask are alike... What is the meaning of good? What does it mean to live a good life? What is the nature of [wait for it 😉] truth/reality? Why are we here? What is the universe? How should we treat each other? etc etc etc etc 14 minutes ago, MigL said: I must say that your thought processes, in equating expanding knowledge of the mechanisms of the universe, with approaching 'truth', are a little confused ( for someone who claims to be a Philosopher ).
