    Nothing is true?creativesoul

    As Descartes told us, there is only one thing we know is really, actually, for real true.
  • Gettier's Gap: It's about time (and change)
    All the same, why justify any belief whatsoever if not to best evidence that the belief is in fact true (i.e., that the belief in fact does conform to that which is real)?

    If no cogent answer can be here given, then, while in no way being infallible, declarative knowledge can only be "a belief which one can justify as being in fact true". Hence, JTB in the sense just mentioned.
    javra

    As I understand justified true belief as it is usually discussed, it does not mean justified to best evidence that it is true. It means really, actually, for real true, which, of course, nothing ever is. That's why JTB is such a bonehead definition.
  • Gettier's Gap: It's about time (and change)
    it's funny that we both took that quote to be supporting our respective sides.

    My side is saying, "belief" already means "I think it's true", and justified means "justified in thinking it's true", so to me, knowledge is just a belief that we're sufficiently justified in - that's what the quote is saying to me. So we don't call a belief knowledge when it's JTB, we call a belief knowledge when it's JB and the J is strong enough. T is the aim of the justification, we and the aim of knowledge, rather than an element inside of it.

    As I understand it, what you've written here is consistent with what Gould wrote and with my understanding of what knowledge is, but, I think we agree, it is not justified true belief as it is usually formulated. You write "knowledge is just a belief that we're sufficiently justified in." I write "knowledge is adequately justified belief based on the consequences of failure." I think we're saying the same thing.

    A good quote! And unless we're giving credence to religious revelation, I can't see another avenue for use of Truth.AmadeusD

    As the quote indicates, Gould was specifically writing about scientific knowledge, not knowledge in general. He was an atheist, but I don't think what he wrote was intended to address religious revelation.
  • Gettier's Gap: It's about time (and change)
    Justification is the reason for believing. Not it's veridicality. Also, that is jettisoning Truth from the concept. Not sure what was missed there, tbh. Truth has no use if your takes are to be the way of things. It's a pointless, senseless concept with no referent.AmadeusD

    We know a belief when it's reached a particular threshold of justification.flannel jesus

    This exchange made me think of this quote from Stephen J Gould.

    In science, 'fact' can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent. — Stephen J Gould
  • Gettier's Gap: It's about time (and change)
    This post is not in response to anything specific discussed so far in this thread, but I just came across this discussion of Robert Boyle's ideas about knowledge in "The Metaphysical Foundations of Modern Science" by E.A. Burtt and I thought it was interesting, by which I mean I am sympathetic to it's point of view. This is a quote from Boyle, an Irish physicist living in the 1600s. "Verulam" refers to Francis Bacon, Baron Verulam.

    “Our great Verulam attempted with more skill and industry (and not without some indignation) to restore the more modest and useful way practised by the ancients, of inquiry into particular bodies without hastening to make systems, into the request it formerly had; wherein the admirable industry of two of our London physicians, Gilbert and Harvey, had not a little assisted him. And I need not tell you that since him Descartes, Gassendi, and others, having taken in the application of geometrical theorems for the explanation of physical problems; he and they, and other restorers of natural philosophy, have brought the experimental and mathematical way of inquiry into nature, into at least as high and growing an esteem, as it ever possessed when it was most in vogue among the naturalists that preceded Aristotle.” — Robert Boyle

    And here's Burtt's comment:

    If your ultimate aim is to know, deductions from the atomical or Cartesian principles are likely to give you most satisfaction; if your aim is control of nature in the interest of particular ends, you can often discover the necessary relations between qualities immediately experienced, without ascending to the top in the series of causes. — E.A. Burtt

    I took a class in psychological measurement in college lo these many decades. This was how precision and accuracy were described. They are both statistical properties. The analogy that was used was to archery. If all the arrows are clustered close together in the bullseye, they are precise and accurate. If they are clustered close together but offset from the bullseye, they are precise but not accurate. If they are centered on the bullseye but are not clustered close together, they are accurate but not precise.

  • Bannings
    Of course they have. But they lie and distort what is going on under their tyrannies, so that criticisms of the regime are vilified as "dehumanizing" and "bad-faith noise" that criticizes a "rational and open" government. That doesn't make it true. Let's not get distracted by "false equivalence" strategies, which will always be yapping at us.J

    When you give them an opportunity, the people in power are the ones who get to decide what “sustains the conditions for open, inclusive, and rational discourse.” That’s why you don’t give anyone the opportunity. If that leads to a somewhat rigid set of rules, that’s the price you pay.

    In the U.S., there's often this almost sacred reverence for free speech as an absolute principle. But I’d argue that speech is only valuable insofar as it sustains the conditions for open, inclusive, and rational discourse. Once it begins to actively undermine those conditions – by dehumanizing people, inciting hatred, or flooding the space with bad-faith noise – its “freedom” becomes self-defeating.DasGegenmittel

    Good post. I’m not used to seeing anger from you. You do it well.
  • Gettier's Gap: It's about time (and change)
    Your proposal works well as a practical heuristic. But without a clearer framework, many of the beliefs we treat as “knowledge” wouldn’t actually qualify — not because they’re false, but because their justification dissolves over time.DasGegenmittel

    The required justification applies at the time when a decision is required, not at some time in the future when previous justifications have "dissolved." If things change, additional justification may be needed, again, depending on the consequences of failure.

    In my work on Dynamic Knowledge (DK) and Justified True Crisis (JTC), the goal isn’t to complicate things unnecessarily, but rather to methodically account for that uncertainty — without falling into dogmatic pseudo-certainty...

    ...JTC doesn’t just focus on the immediate utility of a belief for action. It also emphasizes the awareness of epistemic crisis — the recognition that our justification may be context-sensitive, fragile, or even coincidental.
    DasGegenmittel

    In my experience as an engineer, accounting for uncertainty is the decider's job, it's part of the engineering process and there are specific standards of practice. Strikes me that is true for other fields also. It's the deciders responsibility to evaluate the uncertainty, acceptable risk, and level of justification available and make their decisions on that basis.

    Imagine you see a bottle sitting on a table at 12:00. You say, “The bottle is intact.” At 12:02, you hear a crash — it has fallen and shattered.
    Did you know the bottle was intact?

    Under JTB: ✔ justified (you saw it), ✔ true (at the time), ✔ believed — so: knowledge.

    But epistemically, your statement is unstable. What you actually knew was: “The bottle was intact at 12:00.” Without temporal indexing, your statement becomes retroactively misleading — even though it was “true” in a narrow JTB sense. The JTB model implicitly assumes that once a belief qualifies as knowledge, it remains so — even if the real-world referent (like an intact bottle) changes moments later, unless we explicitly update or retract the claim.
    DasGegenmittel

    I've already stated that JTB is not a good definition of knowledge. My definition - adequately justified belief - addresses the issue you identify, without unnecessary complication.
  • Gettier's Gap: It's about time (and change)
    You mention that knowledge in everyday life isn’t really “stable and reliable” the way we often wish it were—or the way the JTB definition implies. The Gettier case is really just an elegant illustration of this. You suggest instead focusing on practical justification before taking action.

    This aligns very well with my introduction of Dynamic Knowledge: we might try to treat knowledge as a solid foundation, but in reality, there are always gaps and uncertainties. That’s exactly why I propose that in dynamic contexts, we shouldn’t rely on the illusion of “eternal validity,” but rather see knowledge as an ongoing process that must handle uncertainty and revision (JTC).
    DasGegenmittel

    Your formulation seems unnecessarily complicated to me. As I see it, the purpose of knowledge is to allow us to make decisions, to act, effectively and safely. Recognizing there will always be uncertainties in that knowledge, we need to decide how much risk of failure we can tolerate and how much justification we need to limit that risk. In order to provide that level of uncertainty, we need to determine what the consequences of failure are. If I risk losing $10 in a bet, the consequences and required justification are small. If the risks include endangering human life, much more justification is needed.

    So, in this context, knowledge is adequately justified belief based on the consequences of failure.
  • Are moral systems always futile?
    Hey T Clark, thanks for the welcome. I did read your posts, and found myself in agreement with your components of 'human nature', although I was wondering how you would define 'mental'?Jeremy Murray

    I'll give a couple of examples. One of the most prominent is the capacity for language. Another important one is the capacity for what Konrad Lorenz calls "extended consciousness" that most other animals don't have. Over the past year I read two documents by him - A paper called "Kant's Doctrine of the A Priori in the Light of Contemporary Biology" and "Behind the Mirror which deal with the subject and related subjects. Here is a link to the paper if you are interested.

    https://archive.org/details/KantsDoctrineOfTheAPrioriInTheLightOfContemporaryBiologyKonradLorenz

    To say that we can define human nature seems impossible to me, given that our understanding of what that means is inevitably evolving.Jeremy Murray

    Clearly I don't agree with that given I did provide a definition. I'm not a cognitive scientist so my take is a amateur's and, as I noted, others disagree. I've read a few articles, but I can't lay out their arguments. Since the idea of human nature is so important to me, I need to read more people who are critical of the idea.

    I think of this sort of knowledge as an 'act of faith', ultimately...

    But just because you have to 'choose' to believe, the act of faith itself being a choice, does not mean you are wrong. Your concept of this might be perfect, somehow, or it could be the best possible given what we know, in this moment, etc. There are many ways this could be the best way to think without it being objectively true...

    ...To me, we can't 'know' what human nature is, what the right thing to do is, but we can conclude that we are made better by having these 'ideals' to aspire towards, and then acting.
    Jeremy Murray

    Based on what I've written here, it should be clear I disagree with this.

    Your Chuang Tzu quote expresses a very similar premise,Jeremy Murray

    I don't see that. Lao Tzu and Chuang Tzu write about our "Te," what Ziporyn translates as "intrinsic virtuosities" and sometimes "inborn nature."

    I struggle with deontological or utilitarian ethics simply due to the impossibility of objectivity, and my being an atheist. There is no 'leap of faith' for me to take. Only philosophically-informed choices to make. (or so I hope!)Jeremy Murray

    For me, and I think Taoist principles, at least expressed in the Tao Te Ching and Chuang Tzu, there is no leap of faith or philosophically informed choices. It's something I am aware of. As I understand it, Taoism is about self-awareness.

    But I am all for people, such as yourself, making a thoughtful decision to be relativistic, for a variety of possible reasons.Jeremy Murray

    I would not call myself a relativist, although I can see why you would.
  • Are moral systems always futile?
    Hi everyone, I just joined upJeremy Murray

    Welcome to the forum.

    sharper minds than mineJeremy Murray

    There are plenty of unsharpened blades here on the forum. Judging from your post, you're not one of them.

    As for the topic, it seems to me like the concept of 'human nature' is in the same category as 'objective morality', in that both are aspirational and unknowable, but worthwhile pursuits nonetheless. It is in pursuing these ideals that we can honor our human nature / act 'morally'.Jeremy Murray

    If you've read my posts on this thread, you can see I disagree with this strongly. Perhaps it's a matter of definition. Here's how I defined human nature previously in this discussion.

    a bunch of inborn genetic, biological, neurological, mental, and psychological processes, structures, capacities, drives, and instincts which are modified during development and by experience and socialization.T Clark

    I noted that some people don't agree that such an inborn human nature is a major determinant of who we are, so my position is open to disagreement, but it's not "aspirational and unknowable." It's a matter of fact - true or false, open to verification or falsification.

    ...I do believe religion, (human traditions of morality, as they were developed and situated in time, ever-evolving) and even spiritual traditions such as meditation, that can be practiced in secular fashion, all bring value to the pursuit of an 'objective' morality.

    I'm an atheist, but am not hostile to religion itself. Like any ideology or belief system, flawed and imperfect, to my mind, but I respect the 'goodness' of some of the religious people I've known far too much to discount that this is a moral practice with tangible positive outcomes.
    Jeremy Murray

    Your open minded and sympathetic attitude about religion is not a popular one here on the forum, which has a record of knee-jerk religious bigotry.

    Since then, I've been somewhat repelled by the premise, not as a considered stance by those who have done the work to decide on relativism, but rather as a default premise amongst people who might not think much about anything philosophical. A 'lazy relativism' if you will.Jeremy Murray

    As I wrote previously in this thread, I'm with Chuang Tzu when he said -

    Goodness, as I understand it, certainly does not mean humankindness and responsible conduct! It is just fully allowing the uncontrived condition of the inborn nature and allotment of life to play itself out. What I call sharp hearing is not hearkening to others, but rather hearkening to oneself, nothing more. — Chuang Tzu

    I guess that would make me a relativist in your book. I see it more as taking responsibility for my own actions. As I note, stopping others from hurting people without justification does not call for morality - "that's evil" - it calls for reasonable control - "stop that."

  • Tortoise wins (Zeno)
    Zeno's dichotomy paradox corresponds to the mathematical fact that every pair of rational numbers is separated by a countably infinite number of other rational numbers. Because of this, a limit in mathematics stating that f(x) tends to L as x tends to p, cannot be interpreted in terms of the variable x assuming the value of each and every point in turn between its current position and p. Hence calculus does not say that f(x) moves towards L as x moves towards p.sime

    I don't understand how "...every pair of rational numbers is separated by a countably infinite number of other rational numbers." implies "a limit in mathematics stating that f(x) tends to L as x tends to p, cannot be interpreted in terms of the variable x assuming the value of each and every point in turn between its current position and p." It's a model for goodness sake.

    I realize that the infinity gets smaller and smaller, but it still never ends and hence should have no finite boundary. Each digit of pi corresponds to a slice of space, so infinite space makes finite object, a contradiction, so says the Eleatics. What is intuitive for me is to say there are discrete steps, but it's impossible to explain that geometrically. Infinity seems necessary as a tool, not as a truthGregory

    Points are infinitesimally small in three dimensions, lines in two dimensions, and planes in one dimension, yet we use them all the time in mathematics and physics. They can be used as effective, accurate models of the behavior of actual observable phenomena. Why are the infinitesimals we are discussing any different?

    Could you elaborate on this, I'm curious what you mean with it. Is it something along the lines of the Chuang Tzu quote?ChatteringMonkey

    The best expression I've found of the sentiment I'm describing is the Chuang Tzu quote you reference. When I first read it, after already having read the Tao Te Ching, I was struck with a sense of recognition - insight. I think it is the natural expression of Lao Tzu's principles in relation to moral behavior. From what I've seen, the observation in the Tao Te Ching that expresses it best is this, which is from Gia-Fu Feng's translation of Verse 38.

    Therefore when Tao is lost, there is goodness.
    When goodness is lost, there is kindness.
    When kindness is lost, there is justice.
    When justice is lost, there is ritual.
    Now ritual is the husk of faith and loyalty, the beginning of confusion.

  • Gettier's Gap: It's about time (and change)
    Welcome to the forum.

    However, we typically regard knowledge as stable and reliable, a foundation we can trust. Gettier problems like this challenge the traditional JTB definition by revealing cases of accidental knowledge, suggesting that justification, truth, and belief alone are insufficient for genuine knowledge.DasGegenmittel

    Of course what we call knowledge isn't, never will be, and never can be "stable and reliable." This demonstrates that justified true belief definition of truth is fundamentally flawed. JTB does not describe knowledge as we normally think of it, use it, or act based on it. The unnecessary and convoluted Gettier "problem" just highlights that fact.

    My approach? Focus on the practical justification needed before we act on specific knowledge rather than on it's truth.
  • Are moral systems always futile?
    Yes, we have innate moral feelings, maybe even something like a directional moral sense, but I don't think its enough on its own to get fully functional morality. We have a long education period for a reason it would think, unlike other animals.

    If there's a cultural component to how we get our values, if that is part of human nature, then it seem like pointing to human nature as an explanation misses something, or doesn't really answer the question, as there is a yet to be defined component to human nature.
    ChatteringMonkey

    Although my focus was on inborn human nature, I specified that it works by interacting with environmental factors. As I wrote:

    "
    So what is our human nature? I'll go out on a limb here. It is a bunch of inborn genetic, biological, neurological, mental, and psychological processes, structures, capacities, drives, and instincts which are modified during development and by experience and socialization.T Clark

    Human nature isn't the explanation for who we are and what we do. It's part of the answer. We aren't blank slates.

    I do think education, or moral systems, can go to far or go wrong if they veer to far from the basic moral feelings. This is how I see TaoismChatteringMonkey

    I don't disagree, but I think Lao Tzu sends a much more extreme message than that. Whether or not Chinese society, or ours, would be impossible - it seems clear to me that they would be very different.

    I think part of moralities function is social control. Murder derails societies as it tended to lead to bloodfeuds and the like... it was bad for social order. It seems weird to me that you would want to excluded that from morality, as a functioning society is a prerequisite for any kind of human flourishing it seems to me.ChatteringMonkey

    I think social control in the sense I'm talking about it is fundamentally different from morality. The judgment that a behavior is bad or wrong rather than disruptive is also fundamental. They will likely have a significant impact on how the behavior is addressed and how the person acting is treated.

    Maybe this is mostly just a definitional semantic thing.ChatteringMonkey

    I don't think so. It has a big impact on the actions chosen to address unwanted behavior.

    If I remember correctly, Pythagoras or one of those other Greek math guys calculated pi by dividing up a circle into uniform triangular pie slices. It seems intuitive to me, and apparently did to him, that as the size of the slices increase in number and decrease in size, the sum of the area of the triangles approaches the area of the circle with as much precision as we want. Carrying that one step further into calculus using the limit at infinity seems - intuitively - natural and logical.

    I'm not aware of a mathematical definition of an alternative continuum that resolves all of the logical puzzles posed by Zeno.sime

    I'm not sure what you mean by "alternative continuum."

    Zeno's paradoxes when interpreted mathematically, pose fundamental questions concerning the relationship between mathematics and logic, and in particular the question as to the logical foundation of calculus. The existence and utility of the classical continuum is also called into question.sime

    The mathematical interpretation of Zeno's paradox seems straightforward to me. Evaluating limits makes the so-called paradox disappear. What is illogical about that? And what does this have to do with calculus. Representing a continuum as an infinite series of infinitesimals seems like a good model of how the universe works, simple and intuitive.
