Scientists realized there is no "Truth", only a series of better and better models approximating it. But philosophers still talk about Truth, they didn't get the message. As long as we are using leaky abstractions - which means all the time - we can't capture Truth. There is no view from nowhere. |

When philosophers talk about 'Truth', they aren't searching for a perfect static artifact. They're investigating the concept itself, which is very necessary. The entire project of model-building would be meaningless if there were no external reality to approximate. What is it that this "series of better and better models" is converging toward? |

| Yeah sure, all scientists have the same opinion on that matter, while all philosophers have a different obsolete dogmatic view, both camp are perfectly disjoint, and only the first one is acquired this fundamental truth^W continuously improving model always closer to truth^W something relative to something else and disconnected of any permanent absolute. |

| > Scientists realized there is no "Truth", only a series of better and better models approximating it. I don't quite agree with this, unless what you mean is that there's no procedure we can follow which generates knowledge without the possibility of error. This doesn't mean that there's no such thing as truth, or that we can't generate knowledge. It just means that we can never guarantee that our knowledge doesn't contain errors. Another way to put this (for the philosophers among us) is that there is no way to justify a belief (such as a scientific theory) and as such there is no such thing as "justified true belief." But again, this doesn't mean that we cannot generate knowledge about the world. |

| ▲ | estimator7292 5 days ago | parent | next [-] | | There is very little about the universe that is axiomatically true and correct in and of itself. Math is about the only thing I can think of, and really that's in a different category. Everything we know as a species is really just consensus. "Truth" is what we agree it is because the universe does not offer actual truth. What we know is the best guess that our greatest minds can agree on. What we consider to be truth changes far more often than it stands to scrutiny. There are only a very few people from the entire history of our species who have run particle collider experiments and verified first hand what's inside an atom. What they agree on is truth for everyone because almost nobody has the means to test it themselves. And then of course this truth is modified and updated as we find more data. Then old conclusions are rejected and the entire baseline of truth changes. We can be sure of things to however many decimal places as you'd like, but reality itself is fundamentally built on probabilities and error bars. What we think we know is built on probabilities on probabilities. | | |

Math is about the only thing I can think of, and really that's in a different category. My thought is that math (broadly speaking) possesses correctness because of axiomatic decisions. The consequences of those decisions lead us to practice math that can't express everything that we can imagine (e.g., see axiom of choice/ZFC). The math humanity practices today is a result of tuning the axioms to be: self-consistent, and, useful for explaining phenomena that we can observe. I don't believe this math is correct in a universal or absolute sense, just locally. | | |

| ▲ | blackbear_ 5 days ago | parent | prev [-] | | I think you are confusing what we believe to be the truth at a point in time and how the physical world is. Either atoms exist or they dont. Our idea of atom has evolved over time, but the thing that we call "atom" has always been there (at least on the time scale of human civilization). The probabilistic nature of quantum objects isn't really a problem either. Electrons may be particles, waves, both or neither, but the "thing" is a real phenomenon of this world regardless of how we talk about it. Similarly, the truth value of alien existence is well defined: either they exist at this time or they do not. We don't know it for sure, but this doesn't change whether they are actually there or not. | | |
| ▲ | 47282847 5 days ago | parent [-] | | > Either atoms exist or they dont Perfect example, since they only exist as a concept to describe an observation. With higher precision of observation, it became “the new truth“ that most of the time even on the observation level do not actually exist in terms of matter; they “flicker“ fast enough to appear existing at all times. When you look often enough or at the wrong times, there is nothing to observe. | | |
| ▲ | blackbear_ 5 days ago | parent [-] | | > When you look often enough or at the wrong times, there is nothing to observe. Is this because atoms don't exist, or because we are looking in the wrong way due to partial (mis)understanding? The "new truth" that you talk about is just a different understanding of the concept of atom, but the actual thing that we call atom and that exists in the real world (whether as matter or in some other form) has not changed. | | |
| ▲ | glenstein 5 days ago | parent [-] | | Exactly the right question. If atoms are forever retained as a locally true-in-its-domain and at-its-level-of-description phenomena in every future theory, I think they count as real in any important sense. Even classical mechanics is true in the sense of strongly accurate and predictive at its scales of description, as an approximation of something more precisely described by QM. One thing that gets me excited is that there's a tantalizing possibility that the 21st century might have an Einstein-level breakthrough that treats holography and some principle of informational consistency as more fundamental than QM, which is amazing, and would change everything. But even in that hypothetical future paradigm, an "atom" would still be something true and meaningful against that backdrop, and our measurements or knowledge claims about it would still be meaningful. And our progress toward knowledge of the atom was still real progress. It's legitimate to treat our knowledge as limited, subject to revision, or approximating. But treating that grain of truth like it implies no knowledge or progress is in hand is an abuse of the concept. |

Any knowledge is composed from imperfect abstractions, the edge cases of which we don't know. We are taking patterns from our experience, and coining them as abstractions, but ultimately we all have our own lived experience, a limited experience. We can only know approximatively. Some people know quantum physics, others know brain surgery, so the quality of our abstractions varies based on individual and topic. We are like the 5 blind men and the elephant. | | |
| ▲ | rfrey 5 days ago | parent | next [-] | | > Any knowledge is composed from imperfect abstractions, the edge cases of which we don't know. That is a pretty concrete epistemological statement. Is it true? That's not just a game, or a "gotcha". Any discussion about "truth" eventually ends up with the question of what it means to know something, a subject about which you seem to be fairly confident. | |
| ▲ | tshaddox 5 days ago | parent | prev [-] | | A piece of knowledge is a claim about some property of reality, which is another way to say that it's a claim about what is true. Thus knowledge can contain truth and can also contain errors, and importantly it's impossible to guarantee that knowledge does not contain errors. |

Not like those hair-brained philosophers! Sigh. One would have to possess an impressive level of ignorance in the history of philosophy and science in order to hold such a view.

Scientists aren't after truth. They're after facts.
Truth depends on context. Facts are indisputable.
Imagine you're looking at your computer screen and you see green. Someone else looking at their computer screen might be red/green color blind and might see a shade of brown. The color being green and red can simultaneously be true. But the fact might be that the displayed color is a mix of certain EM frequencies, and each person's brain interprets those frequencies differently. This to me reads as semantic games; let me rephrase your example: "Imagine you're looking at your computer screen and you see green. Someone else looking at their computer screen might be red/green color blind and might see a shade of brown. The color being green and red can simultaneously be factual. But the truth is that the displayed color is a mix of certain EM frequencies, and each person's brain interprets those frequencies differently." | | |
| ▲ | inetknght 5 days ago | parent [-] | | > can simultaneously be factual. But the truth is that the displayed color Your rephrase is incorrect. "Red" and "green" depends on what your brain interprets. That doesn't change the underlying EM frequencies of the color you see. Therefore, red and green are truth while EM frequencies are factual. | | |
| ▲ | postmodern100 5 days ago | parent [-] | | My brain (the one in my head) can only interpret red or green, given its makeup and the rest of the state of the universe including the display that I'm looking at. Therefore, it's a fact that my brain interprets red instead of green, or vise versa. It's a fact for someone else's brain that they interpret it as green instead of red. | | |
| ▲ | inetknght 5 days ago | parent [-] | | > my brain interprets > someone else's brain Yes, like I said: it depends on context. Red and green is interpretation, which depends on context. That's truth. Sure, it's indisputable that one brain and a different brain can have different associations for names of colors. That's a fact. But the name of the color that each brain associates with corresponding input depends on context. That's truth. | | |

| ▲ | card_zero 5 days ago | parent | prev [-] | | Epistemology fight! Facts are ideas like there are 60,000 species of beetle. They're different from other ideas in that they don't explain very much, don't really contribute to understanding, and are quite boring. They are disputable, because my source for that particular fact is quite old, and by now we may think the fact is that there are 70,000 species of beetle. Objective facts are actually true, and nobody is ever completely, indisputably certain of those, although in some fields like mathematics we try very hard to say indisputable things, and in others like literary criticism we don't, because the subjective is of more interest in that context - that is, there is higher tolerance for vagueness. But really every claimed statement is a subjective attempt to approach the objective, which is forever beyond us, but we can travel in its direction. |

| Scientists are trying to make predictions about the future based on past experiences (inductive reasoning). Philosophers aren't necessarily trying to do that. You can't get to capital T truth via inductive reasoning like science uses. Just because the apple fell from the tree every single previous time, does not necessarily imply that it is going to fall down next time. But if you are after other forms of reasoning its possible. 1+1 will always equal 2. Why? Because you (implicitly) specified the axioms before hand and they imply the result. Talking about capital T truth is possible in such a situation. So its perfectly reasonable for philosophers to still be after capital T truth. They are doing different things and using different methods than scientists do. |

| All you've accomplished here is to repackage the tired "there are no absolute truths" meme |
| |
| ▲ | psychoslave 5 days ago | parent [-] | | Yes, that’s a nice self-contradicting statement to ignite thoughts. One possible resolution is to conclude "even granted that absolute truths do exist, and humans can experiment the intuition that they indeed exist, doesn’t imply that humans can reach absolute truth and fathom it down." | | |
| ▲ | Belopolye 5 days ago | parent [-] | | I don't think there can be a resolution on a fundamental level, unless you count some therapeutic attempt at "we're going to pretend like we can grasp truth for the sake of convenience, or because the alternative is too uncomfortable" as a resolution. The consequence of what it means is that we can't have any justified claims or knowledge at all. If you can't even count on the law of identity you've lost all intelligibility. Alternatively, objective truth does exist and humans can comprehend it, and the issue of truth versus the development of how we come to understand it is a semantic one (I rather like the distinction between historie and geschichte in German). To my mind, where we've gone wrong is that we began by assuming transcendentals, holding certain axiomatic, a priori metaphysical assumptions that make the scientific method possible, and then turned around and denied that transcendentals exist in the first place- undercutting the foundation rather than really questioning our tooling or our capacity to understand the data. | | |
| ▲ | psychoslave 5 days ago | parent [-] | | >The consequence of what it means is that we can't have any justified claims or knowledge at all. Just that we can’t claim all of our knowledge are equally close to the absolute truth we suppose to exist. The belief that the current attention exist is among the closest thing we can have to an absolute truth. That something like "I" exists is a step further away. That an external world exists is yet an other step further. That 1+1=2, it depends if we take the road of Principia Mathematica à la Whitehead&Russel or if we take more faith in intuition on sensory/memory inputs + reward/penalty from what teachers asked us to integrate at primary school. >If you can't even count on the law of identity you've lost all intelligibility. Change as sole stable permanent foundation is harder to play with, at least by the most spread education systems in western civilization (outside it I don’t have first hand experience), and the concept of identity can be derived from it as a transitional side effect. Not that identity must be dropped entirely, but then considered under different perspectives. Somehow like we can build our math under ZFC or category theory (or without anything so firmly and meticulously founded really), and at high level notions it doesn’t prevent us to reemploy familiar patterns. Identity as a foundational block is not only an issue for humanity at epistemological level, but also at psychological and societal level. Used as inscrutable fundamental black box, it can actually prevent intelligibility and sound reasoning in all the contexts it’s broadly employed. >To my mind, where we've gone wrong is that we began by assuming transcendentals, holding certain axiomatic, a priori metaphysical assumptions that make the scientific method possible, and then turned around and denied that transcendentals exist in the first place- undercutting the foundation rather than really questioning our tooling or our capacity to understand the data. That’s probably smoothing "we" very broadly here. "We" also have a very firm tendency to easily build disagreement on every matters and the rest. Nonetheless I would be interested to know more about what leads to this perspective. |

Science is orthogonal to belief in ultimate truth, and scientists have very diverse opinions on that point. Science is about finding more useful models to predict future observations, but whether and how that relates to truth is a question outside of the domain of science. |
