It amazes me that people seem to be so unworried about the thorough poisoning of the well. Though given the extent that the well of the entire internet has been so thoroughly poisoned, perhaps it's just more of the same. But the whole story gives a good basis for thinking of this as the post-truth society. No-one seems to care much. I suppose it's all good fun and labour-saving - until you get on the wrong end of a lie. So much for the vision of information freely available to everyone.Now with AI, we have photo and video fakes, voice fakes, that look as good as anything else, so we have a new layer of deception. We have the “hallucination” which is a cool euphemism for bullshit. — Fire Ologist
I do (ignore it). I have yielded to the temptation occasionally, but never found the summaries at all helpful. Also, I reason that the motivation for offering it so freely is to get me hooked. Perhaps, in due course, a more balanced view will develop, at least in some quarters.This is why I was shocked that philosophers, of all people, wouldn't be ignoring the "AI summary" invitation at the top of the search results? — bongo fury
To be fair, AI might pick up some of the donkey work in presenting and even organizing information. But not the labour of (trying to) check it.I'd have thought the relevant job description, that of filtering the results for signs of trails leading to real accountable sources, would have to disqualify any tool known ever to actually invent false trails, let alone one apparently innately disposed to such behaviour? — bongo fury
That's bad enough. But I am told - or hear rumours - that AI actually gets things wrong. Of course, that makes it no worse than people. The problem is, however, that because it is a machine, people will trust it, just as they trust existing computers and internet. That is clearly naïve, unbecoming a philosopher. What would help would be an AI trained as a fact-checker. But then, it would have to understand exaggeration, minimization, accuracy, approximation, not to mention distinguishing fair and reasonable interpretation from distortions and misrepresentations.I think this is the fundamental problem. AI does no research, has no common sense or personal experience, and is entirely disconnected from reality, and yet it comes to dominate every topic, and every dialogue. — unenlightened
Well, I'll just leave you to it. There's not much fun to be had here.As a solipsist, that's the core of my worldview. — Copernicus
You miss the point where the distinction arises. If your vision is of peace and justice for everyone, it is altruistic. If your vision is of your own well-being and prosperity alone, it is selfish.You serve your vision of a better world. — Copernicus
Thanks. Very helpful.No. — Copernicus
You only read part of what I said. You will surely not see what you choose not to look for.Exactly. Everything is about that one way or another. — Copernicus
How would you know?No one escapes it. — Copernicus
Thanks for that.Great post, just that one line sticks out to me as something that others might gloss over thus prematurely proving the OP's premise as valid. — Outlander
There's a case for considering generosity to one's children is a kind of selfishness. But that just reveals that what counts as selfishness is not necessarily obvious. What do we make of the virtue of looking after one's family? In the context of wider society, it can look like selfishness. In the context of traditional individualism, it is altruism.But they're still your children. — Outlander
Yes, but the point is that I consider those happy children to be a benefit and not a drag. The rest of it is far from guaranteed. However, if my generosity to them was predicated on those happy outcomes. that would undermine my claim to generosity.It benefits your family and existence directly to have happy children who live productive lives, possibly earning lots of money, holding you in high regard, esteem, and favor, and then taking care of you when you're enfeebled. — Outlander
Well, we can all agree that every action has a motivation of some kind and that motivation "moves" the agent. To conclude from that that every action is selflish is just playing with words. What matters is what moves the agent. If I respond to pain with sympathy and the attempt to help, or take my children to the sea-side because their delight gives me pleasure, those is at least a candidates for a selfless actionPhilosophy has long divided human action into the “selfish” and the “selfless.”
Yet such a distinction may be more linguistic than real. Every deliberate human act is born from an internal desire — whether that desire seeks pleasure, avoids pain, fulfills duty, or maintains identity. — Copernicus
Very few actions originate from the actor's internal state. Most of them are a response to the world around us. All the people you mention - the soldier, the mother, the philanthropist - are responding to the situation they are in, in the world they are in.If every action originates from the actor’s internal state, then no act can be wholly “selfless.” Even apparent self-sacrifice — the soldier dying for his country, the mother starving for her child, the philanthropist donating wealth — finds its roots in personal satisfaction, emotional fulfillment, or existential meaning. — Copernicus
There's truth in that. Where does the meaning, the discipline, the other come from?Every act of kindness, every moral code, every love story is a negotiation between biology and meaning, desire and discipline, self and other. — Copernicus
Maybe. But the individualist who cannot imagine goods that are shared by everyone will never understand individuals. For better or worse, we are social beings. Arguably, we all benefit from that. But perhaps you can't recognize the benefits. We (mostly) respect each other's property, and as a result, I can enjoy my property (mostly) in peace. Because people mostly respect the rule about driving on the left or right, everyone can drive more safely. Because people mostly respect their own promises, everyone can do their business. These things are not oppressions, they are enablers.Until the communitarian comes to terms with the fact of our separateness, of our individuation, the communitarian Good can never be imagined in any other sense as individual, selfish desire. — NOS4A2
Say someone was born with the need to help others, sometimes to the detriment of other wants and needs, but if one of their needs is to help others, and they find satisfaction in helping others, then would that fall into your definition of "selfish"? — Harry Hindu
The virtue lies in the good feeling. The difference between someone who gets pleasure from the pleasure of others is different in important ways from the person who gets pleasure from the pain of others. The one spreads pleasure, the other spreads pain. Who would you prefer for your next-door neighbour?because it's giving them a good feeling, at least, if no other transactional motive is present. — Copernicus
Oh dear, you will have to find your way out of that cage on your own - unless someone helps you. On the other hand, if you can recognize that solipsism is a cage, there is some hope for you.The self is caged in the solipsistic bubble and can only act from within. — Copernicus
Yes, the vocabulary must be really important. People usually identify schools by their shared doctrines, but actually, I think it is just as much about their disagreements. That's what the shared vocabulary enables. There's also the social dimension.It is off topic to this OP, but I often wonder about self-identified schools of thought and the range of vocabulary shared amongst different views represented through them. I won't try to talk about that in this thread. — Paine
The difference between empathy and sympathy comes up here. I've never been very clear about it. "Identifying with you" is a whole language game in it's own right. One might object to the phrase, because in that process, I do not for a moment imagine that I am you. What I imagine is myself in that situation.Alternatively, the logical (grammatical) “cannot” is that I can’t know your pain without accepting it, identifying with you. — Antony Nickles
Yes. Doesn't he say, somewhere in the PI, that we naturally respond to another's pain by trying to relieve it. I'm inclined to say that anyone who doesn't understand that, and why, it is an appropriate response, doesn't understand what pain is.but, in doing so (not as an argument for), we also see a different relationship to another’s pain than knowledge. — Antony Nickles
I see your point.But I’m not sure if pointing out just any alternative criteria would be convincing, nor do I think he means to say the argument would be over if they were aware of the nature of what they were objecting to, as if convention is more justified or powerful or certain, because the trick is to capture the “difficulty” seen by the metaphysician (and philosophy in general), which I take as real and actual and not something he is dismissing. — Antony Nickles
That's all very well. Then I thought of the Ukraine's argument with Russia. It wouldn't fly, for either side. Both sides would object that W has missed the point of the argument - doesn't understand it. It isn't about geography. That's the thing. There's no neutral ground on which one can resolve disagreements.He feels tempted, say, to use the name "Devonshire" not for the county with its conventional boundary, but for a region differently bounded. He could express this by saying: "Isn't it absurd to make this a county, to draw the boundaries here?" But what he says is: "The real Devonshire is this". We could answer: "What you want is only a new notation, and by a new notation no facts of geography are changed". — p. 57`
The fact that he puts this as a qualification, an after-thought, in brackets, tells me that he does think that his geographical point of view is better. But I'm not at all sure that there is any privileged notation that is better or worse than any other from a theoretical point of view.(It is true, however, that we may be irresistibly attracted or repelled by a notation. We easily forget how much a notation, a form of expression, may mean to us, and that changing it isn't always as easy as it often is in mathematics or in the sciences. A change of clothes or of names may mean very little and it may mean a great deal.) — p. 57`
It's based on my interpretation of references in Berkeley and Hume to "the academics" or "the schools" or "schoolmen". Aristotelianism as such is usually though to be over by 1700. That doesn't mean that nobody studied either Plato or Aristotle after 1700, and Aristotelianism was a major opposition to the new science and Enlightenment.I am surprised by your lack of surprise. The shared use of terms by the two authors is clearly evident in comparisons of their texts. That includes the term 'experience', that invokes what is called empria by Aristotle which led to the word "empirical." — Paine
Of course it is. It's clearly a precursor. I'm not sure it's exactly our idea or Kant's idea. That quotation doesn't mention experience, which I think is the key idea for us.What is primary is what is sought throughout Aristotle. — Paine
I didn't know that. It isn't a surprise, though.Kant's terms can be said to move across the background of their Aristotelian versions. — Paine
I know that list. But I've not heard it called that before.I need to get more chores off the honey do list first. — Paine
That is enough to tell me what I need to know.I will pursue my Buddha nature by not commenting on the SEP article. — Paine
The receptivity of perception in Aristotle can be seen as a parallel to that of the intuition of sensibility.
Yes. But there's a vast difference in the "mechanism". Aristotle's mind is, so far as I can see, almost entirely passive. Quite unlike Kant's - I guess that's his great contribution.
— Paine
But where Kant directly rebukes Aristotle is over his use of logic at A268/B324. — Paine
I don't read that as critical of Aristotle, so much as critical of "schoolteachers and orators". I was also very impressed that Kant (seems to) retain some concept of form and matter. How he reconciles that with the new science I cannot imagine.On this is grounded the logical topics of Aristotle, which schoolteachers and orators could use in order to hunt up certain titles of thinking to find that which best fits their current matter and rationalize or garrulously chatter about it with an appearance of thoroughness
I can understand the a priori as about the possibilities of experience, and then it makes sense that the senses are about actual experience. But now I don't understand why he says this. I suppose that pure understanding/reason is not the same as the mixed understanding of possible experiences. But then it seems odd to me that he seems to think I must grasp all the possibilities before I can grasp any actual experiences. Surely understanding some possibilities would be enough.The principle that throughout dominates and determines my Idealism, is on the contrary: "All cognition of things merely from pure understanding or pure reason is nothing but sheer illusion, and only in experience is there truth. — Prolegomena to Any Future Metaphysics, page 374, or page 69 in the linked document
Yes. I guess his great contribution was to break the empiricist/rationalist dilemma by showing that both are necessary. Which should have been obvious all along.Instead of seeking two entirely different sources of representation in the understanding and the sensibility, which could judge about things with objective validity only in conjunction, each of these great men holds on only to one of them, which in his opinion is immediately related to things in themselves, while the other does nothing but confuse or order the representations of the first. — CPR A270/B326
Well, that just reinforces my opinion that there is no set way to distinguish between them. So your synonymy is not wrong. I'm usually very sceptical about claims of synonymy. There's usually a difference to be found. In this case, perhaps, too many differences for comfort.Some epistemologists use "warrant" to refer to a justification sufficient for knowledge. The conditions that make it so are open to debate. Nevertheless, I was just treating warrant as synonymous with justification. — Relativist
It may be a loose way of speaking, but it make sense to me. Thanks. Very helpful.That’s what I get out of it, anyway. Loosely speaking. — Mww
Isn't "warranted" just another way of saying "best"?
— @Banno
No. Being warranted means to be rationally justified.
A subjective "best" inference may, or may not, be warranted. — Relativist
We seem to be circling. Being warranted means to be rationally justified, and something is rationally justified if it is warranted. The best explanations are the ones which are rationally justified, and those are the ones that are warranted, and they are the ones we accept. A subjective best inference may not be warranted, but then it would not be the best inference, and so not justified, and not the best. — Banno
A statement authorizing movement from the ground to the claim. In order to move from the ground established in 2, "I was born in Bermuda", to the claim in 1, "I am a British citizen", the person must supply a warrant to bridge the gap between 1 and 2 with the statement "A man born in Bermuda will legally be a British citizen" (3). — Wikipedia - Stephen Toulmin
My puzzlement about what "conform" means continues. It occurred to me that taking into account what Kant may have been reacting to might be illuminated by looking again at Aristotle. (It is possible that he actually had Aristotle in mind, but I'm not historian enough even to suggest that.)Hence let us once try whether we do not get farther with the problems of metaphysics by assuming that the objects must conform to our cognition, which would agree better with the requested possibility of an a priori cognition of them, which is to establish something about objects before they are given to us. — CPR, Bxvi
SEP - Aristotle's Theory of MindHis (sc. Aristotle's) primary investigation of mind occurs in two chapters of De Anima, both of which are richly suggestive, but neither of which admits of easy or uncontroversial exposition. In De Anima iii 4 and 5, Aristotle approaches the nature of thinking by once again deploying a hylomorphic analysis, given in terms of form reception. Just as perception involves the reception of a sensible form by a suitably qualified sensory faculty, so thinking involves the reception of an intelligible form by a suitably qualified intellectual faculty (De Anima iii 4, 429a13–18). According to this model, thinking consists in a mind’s becoming enformed by some object of thought, so that actual thinking occurs whenever some suitably prepared mind is “made like” its object by being affected by it.
This seems very plausible to me. But since it is a question of how the object is treated, I wonder what ground there is for talking of two different kinds of object. Put the question this way, what determines whether a given object is treated in accordance with sensibility or in accordance with pure speculative reason. Or is it like the difference between smells and sounds, where the difference is guaranteed by the nature of the "intuition"?In other words, the Critique does teach the twofold aspect, but not of the object. It is the two-fold aspect of the human intellectual system as laid out in transcendental philosophy. It is by means of that system that an object is treated as an appearance in accordance with sensibility on the one hand, or, an object is treated as a ding an sich on the other, in accordance with pure speculative reason. — Mww
I'm not at all sure that the latter alternative will stand up to Berkeley's "master argument". (He concludes too much in his conclusion that the tree doesn't fall unless someone perceives it. The tree falls and if some one had been there, they would have perceived it.)We can also ask what manner of existence they could have for other percipients or absent any percipients at all — Janus
That's right. Doesn't that mean that you have to recognize the plausibility of the "conspirator's" narrative? Which is a long way from attempting to "debunk" anything. It seems to me that it actually means putting one's own non-conspiracy narrative at risk. Starting from the belief that the narrative is obviously wrong, is adopting a stance from which it is impossible to do this.So if you want to argue a counter-narrative, it has to engage with the conspirator’s structure of belief on what may be its own well-structured level. — apokrisis
Perhaps it is necessary to bear in mind that it is possible for two incompatible interpretations of data to be right, or at least not wrong.By ackowledging our beliefs are warranted by abduction, a discussion is feasible, and can be productive for both sides. Productive in various ways: undercutting the other guys belief ("proving" him wrong, in an abductive sense); or simply helping both sides to understand the other's point of view - when both positions are defensible. — Relativist
Yes. But we seem to prefer to reach a conclusion, even when we don't need to decide. Perhaps we just don't like the uncertainty of indecision.Yes, a single, specific real explanation isn't always possible. A more general explanation may still be possible, or at least some may be ruled out. It can be appropriate to reserve judgement. — Relativist
The two-aspects reading attempts to interpret Kant’s transcendental idealism in a way that enables it to be defended against at least some of these objections. On this view, transcendental idealism does not distinguish between two classes of objects but rather between two different aspects of one and the same class of objects. For this reason it is also called the one-world interpretation, since it holds that there is only one world in Kant’s ontology, and that at least some objects in that world have two different aspects: one aspect that appears to us, and another aspect that does not appear to us. That is, appearances are aspects of the same objects that also exist in themselves. So, on this reading, appearances are not mental representations, and transcendental idealism is not a form of phenomenalism.
I'm not surprised. There's always a delicate balance to be struck there.All the thinkers Kant responded to had different ways of framing what is intuition, phenomena, ideas, logic, and categories. They were arguing within a set of parameters. The problems we have looking in from outside is that we cannot share that set without problems of translation. — Paine
Space and time are big issues in philosophy, and I'm not an expert. But I do agree that we do not experience space as a phenomenon. I wouldn't say that it is a condition for sensibility, but rather a principle of interpretation of the phenomena.I meant to say that taking intuition of space and time as a process of my perception raises the question of how "objective" it is. That ties into Kant's beef with Berkeley who treats space as an experienced phenomenon. Kant argues that it is, rather, an a priori condition for sensibility: — Paine
My word. That is a surprise. He sounds like a radical 20th century analytic philosopher.The principle that throughout dominates and determines my Idealism, is on the contrary: "All cognition of things merely from pure understanding or pure reason is nothing but sheer illusion, and only in experience is there truth." — Prolegomena to Any Future Metaphysics, page 374, or page 69 in the linked document
This just defeats me. Perhaps you can paraphrase it for me?Space and time, together with all that they contain, are not things nor qualities in themselves, but belong merely to the appearances of the latter: up to this point I am one in confession with the above idealists. But these, and amongst them more particularly Berkeley, regarded space as a mere empirical presentation that, like the phenomenon it contains, is only known to us by means of experience or perception, together with its determinations. I, on the contrary, prove in the first place, that space (and also time, which Berkeley did not consider) and all its determinations a priori, can be known by us, because, no less than time, it inheres in our sensibility as a pure form before all perception or experience and makes all intuition of the same, and therefore all its phenomena, possible. It follows from this, that as truth rests on universal and necessary laws as its criteria, experience, according to Berkeley, can have no criteria of truth, because its phenomena (according to him) have nothing a priori at their foundation; whence it follows, that they are nothing but sheer illusion; whereas with us, space and time (in conjunction with the pure conceptions of the understanding) prescribe their law to all possible experience a priori, and at the same time afford the certain criterion for distinguishing truth from illusion therein. — Prolegomena to Any Future Metaphysics, page 374, or page 69 in the linked document
That's all right, then.I, too, am learning from this discussion. — Paine
I see from later comments that you are painting a door. That's a hard task, because a vertical surface promotes drips. I was, however, rather surprised. I always thought that the only way you could paint an appearance was by painting a picture.I will try to respond to some other of your comments but need to get back to painting a specific appearance. — Paine
So where does probabilistic reasoning fit? An example of a conclusion that can approach certainty in degree, but never be absolutely certain in kind. Bear in mind, that probability is, by definition, defined by an outcome, of which the probability, by definition, is 1 or perhaps 0. (I'm not saying the outcome always has to happen, just that each probability defines an outcome.)By contrast, probabilistic reasoning always carries qualification: no matter how small the probability of error, there remains some chance that the conclusion is false. Thus, probabilistic conclusions can approach certainty in degree, but they can never be absolutely certain in kind. — Sam26
I meant that Hume does not question the idea of causation itself; he questions, and rejects, a particular account of what (efficient) causes are.However, I think it is a misrepresentation to call Hume a sceptic about this issue. — Ludwig V
I was referring partly to his rejection of metaphysics as such, and to his criticism of the traditional conception of causal powers.Ludwig rightly emphasizes that Hume rejects the idea of causation as a metaphysical reality. — Banno
That's right. For Hume (by implication), association of ideas and impressions is the one piece of equipment built in to your minds. (Contrast Kant). The thing is - again by implication - it is a causal account. Again, it would be very odd, wouldn't it, if a sceptic about causality proposed causal relationships to explain what causes are. I think the best way of understanding this is by comparison with Wittgenstein's exasperated "This is what I do."Operant and classical conditioning in animals (and in humans), for one example, would be impossible without such innately held means of association. — javra
Yes - emphasis on interaction. Hume doesn't seem to escape from the passive observer trying to piece the world together. But causality plays a vital role in our ability to do things in the world and to change things in the world. I think there is still a hunger for something beyond regularities - as everyone keeps reminding me, correlation is not causality. If that's not looking for a secret power, what does it mean? Regularities are a brute fact, perhaps.On this view, causes are not waiting out there in the world to be discovered; they are part and parcel of the way we interact with the world. — Banno
Well, yes. But we do still use purposive explanations; the difference is that we only use them in specific domains and we don't (most of us) have a grand overall hierarchy of purposes and values. However, I'm not sure that material and formal causes make much sense any more.but it's clear Hume rejected the Aristotelian idea of causation, replacing it with habit and custom. — Banno
But, as facts go, Hume never once claimed that causation was in fact illusory … hence, that there was no objective truth to causes (not in these or any other words). — javra
Mr. Locke divides all arguments into demonstrative and probable. In this view, we must say, that it is only probable all men must die, or that the sun will rise to-morrow. But to conform our language more to common use, we ought to divide arguments into demonstrations, proofs, and probabilities. By proofs meaning such arguments from experience as leave no room for doubt or opposition. — Enquiry, section VI, Probability, footnote to title
Yes, I knew that he explicitly criticised Berkeley somewhere. Thanks for the reference.Berkeley is, in fact, mentioned by name at the beginning of the Refutation of Idealism: — Paine
I'm not sure, but I think the correct answer starts from the fact that space and time are infinite. But it seems absurd to say that I have (actually) got infinitely far outside myself just because I have a mathematical function in my head that is infinite.One question is how far outside of myself have I gotten if it is my intuition of space and time that allows for the possibility for the experience. — Paine
I'm pretty sure that Berkeley would not recognize this critique. As I remember it, he argues (rightly. as it turns out) that space is relative, not absolute. He does claim that space is not absolute, but that doesn't mean that he claims that space is impossible. Since he doesn't have a concept of things-in-themselves, it seems a bit of a straw man to space can't be a property (??) of them. It would seem, however, that Kant thinks that space is absolute. How does that square with his idea that space is an intuition? Thinking about this, it seems that Kant's (and Berkeley's) conception of space seems to be that it is something that exists as a vessel or a medium in which objects have their existence. I don't see that. The existence of objects in space and space itself are not two separate discoveries. Each depends on the other, conceptually speaking.Berkeley, who declares space, together with all the things to which it is attached as an inseparable condition, to be something that is impossible in itself, and who therefore also declares things in space to be merely imaginary. Dogmatic idealism is unavoidable if
one regards space as a property that is to pertain to the things in themselves; for then it, along with everything for which it serves as a condition, is a non-entity. — CPR B274
Well, yes. Except that the distinction between me and objects outside me requires that both are established in the same argument. I don't see how one could establish my own existence first and then establish the existence of objects in space outside me. Now we have to go back to the cogito and its implications.The mere, but empirically determined, consciousness of my own existence proves the existence of objects in space outside me — B275
I, represented through inner sense in time, and objects in space outside me, are indeed specifically a wholly distinct appearances, but they are not thereby thought of as different things. The transcendental object that grounds both outer appearances and inner intuition is neither matter nor a thinking being in itself, but rather an unknown ground of those appearances that supply us with our empirical concepts of the former as well as the latter. — CPR A379
The way he expresses this thought is - a bit awkward, because he seems to allow us to formulate our questions and then ask us not to press them. But once a question is asked, it is necessary to respond, either with an answer or an explanation why the question is illegitimate. Sadly, experience does in fact pose questions to us that invite us to push at the boundaries. My favourite example here is the discovery of pulsars. This happened because a radio signal received by a radio telescope in Cambridge (UK) that in some ways was entirely unremarkable could not be explained, until an entirely new kind of astronomical object - the pulsar - was posited and then proved (by experience with some help from mathematical calculations) to be the explanation. Kant's limit seems arbitrary.If, therefore, as the present critique obviously requires of us, we remain true to the rule established earlier not to press our questions beyond that with which possible experience and its object can supply us, then it will not occur to us to seek information about what the objects of our senses may be in themselves, i.e., apart from any relation to the senses. — CPR A379
This isn't psychology as we now know it, is it? Still, that's not important. I have say, I was pondering whether one could argue that appearances exist and therefore are real in their way and consequently things-in-themselves. It seems I've been headed off. But I still need to ask how appearances can be appearances of things-in-themselves and things-in-themselves be completely unknown.But if a psychologist takes appearances for things in themselves, then as a materialist he may take up matter into his doctrine, or as a spiritualist he may take up merely thinking beings (namely, according to the form of our inner sense) as the single and sole thing existing in itself, or as a dualist he may take up both; yet through misunderstanding he will always be confined to sophistical reasonings about the way in which that which is no thing in itself, but only the appearance of a thing in general, might exist in itself. — CPR A379
Yes, that's quite right. I think, though, that philosophers have always been more interested in how new knowledge is acquired, so tend to focus on that. What they don't pay enough attention to, in my opinion, is how important the spread of knowledge is and how dependent new knowledge is on knowledged that has already been acquired.Much of our knowledge comes through — Sam26
That's complicated. Some probabilistic reasoning is absolutely certain. The odds of a coin toss are exactly and without doubt 1/2. Empirical probabilities less so, although in practice they seem to work quite well. I don't know how reliable Bayesian probabilities are, but, given the difficulty of verifying them (in one-off cases), I set even less store by them. But note that probabilities have no meaning unless and until there are outcomes - at which point the probability becomes 1 or 0.Almost all justification is fallible, not just testimony. Why? Because most knowledge relies on probabilistic reasoning, including science. — Sam26
The search for definitions is often a matter of codifying what we actually do. It is a very hard thing to do perfectly, partly because the rigidity that goes along with that can end up in conflict with the more flexible and dynamic practices of actual use.To better understand the ready-existent regulations by which something operates is not the same as pigeonholing everything into rules of one’s own creation. — javra
There are various understandings of the world and some of the things in it that can't be communicated through propositional true/false knowledge. But there are other ways of communicating - poetry, pictures, music, dance.a mystic’s understanding of reality at large cannot be shared in the complete absence of JTB knowledge regarding this understanding, via which the understanding could then be convincingly communicated to others. — javra
Surely that example is easy to communicate in common-place ways. What is harder to communicate by means of articulate rules is different. Curiously, how to use words is one of them. But how to be respectful or friendly are not like that, either.More mundanely, though, most understandings among adult humans in a society are commonly held by all individuals (e.g., the understanding of which side of the road to drive on). — javra
Yes, but you know when the understanding clicks because you know when the child is using the words correctly.But consider how kids learn language: they must come to their own understanding regarding what words in their proper contexts signify. One cannot impart this understanding to children directly (in contrast to how a JTB can be directly imparted among adults), but can only lead the way toward it via affirmations and negations regarding what is correct. This until the understanding clicks. — javra
Doesn't this show that all three are interwoven as different aspects of knowledge?JTB, on the other hand, will require a) belief (that is both true and endlessly justifiable in valid manners in principle), b) some measure of understanding, and c) awareness. — javra
I was very pleased to see you include testimony. Because it enables us to pass on what we know It is critical to our practice of knowledge. We all stand on the shoulders of others and our society would be greatly impoverished if testimony were not an effective way of communicating it. However, accommodating it in the standard JTB framework is tricky. It requires acceptance of fallible justifications.The five justificatory routes identified in JTB+U illustrate this point. — Sam26
Yes, I agree with that.In this way, JTB+U brings Wittgenstein’s therapeutic insight into constructive form: it dissolves confusions about “know” by looking at use, and it offers a framework that captures the grammar of knowledge as it is lived in our forms of life. — Sam26
I thought that knowledge just is an attitude to a proposition. In what other form could it enter into philosophical consideration? I think it is useful to see "know" and "believe" in the context of "think", "suppose", "imagine", "deny", "assert" and Frege's puzzle is indeed a puzzle.Sometimes knowledge enters philosophical consideration in the form of a propositional attitude. — frank
Well, there's some truth to that. But I think that it misses the point and over-extends a useful idea. It would be a bit misleading, wouldn't it, to parse "I wish I had a red flower for a buttonhole" as expressing a positive attitude to the proposition "I have a red flower for my buttonhole"; the object of my positive attitude is the red flower, once it appears in my buttonhole.Some philosophers and linguists also claim that sentences like ‘Jill wanted Jack to fall’, ‘Jack and Jill are seeking water’, and ‘Jack fears Jill’, for example, are to be analyzed as propositional attitude ascribing sentences, — sep article on propositional attitude reporting
OK. It's just that it seems to me that there are always endless ways to screw things up, but very few to get things just right. Though some mistakes may be small enough to be unimportant.And that's just the nature of what a mistake is, something which eludes judgement. — Metaphysician Undercover
I'm very much in sympathy with the sentiment. But Kant was right not to mention Berkeley here. He does distinguish between those experiences which have a cause that is not myself and those that are caused by myself. His criterion is that the latter are less "vivid" than the former.The proof that is demanded must therefore establish that we have experience and not merely imagination of outer things, which cannot be accomplished unless one can prove that even our inner experience, undoubted by Descartes, is possible only under the presupposition of outer experience.
On my understanding of a priori, we don't know anything about how the world is before we experience it. The clue is in the label - the a priori is what we know before experience. But if it is just a metaphor, we need to be a bit careful in interpreting int. It's hard to see how we could know anything about the objects of experience before experience. On the other hand, mathematics and logic could be seen as telling us about what objects are possible in experience.If intuition has to conform to the constitution of the objects, then I do not see how we can know anything of them a priori.
Yes, I get that. I suppose it's not an unreasonable idea. But it doesn't explain the metaphors that riddle his language.The analogy with Copernicus is to demonstrate how mutually exclusive the two standpoints are. — Paine
Yes, indeed. I hope lunch was good.How some of us went from this location to reading "things-in-themselves" as "mind independent" is a long and winding road through perilous terrain. — Paine
Yes. Does that fit with the standard analytic view of the a priori? I think not. Yet there is something important here, I suspect.We don't know anything of objects or phenomena in general a priori—in terms of what commonalities we can know about all objects without actually consulting particular objects in real time, we must reflect on their general characteristics as perceived. That is we must reflect on prior experience of phenomena in order to see what they all have in common. — Janus
I don't think you can separate experience from knowledge in that way, unless you think you can catch the wild goose of raw experience.Experience is prior in time to knowledge but the possibility for experience is prior as a condition. — Paine
Are there two roads to the same destination or different roads to different destinations?In the Preface, objects of experience are either made present to us through an intuition that has to "conform to the constitution of the objects" or by means of our processes of reason. — Paine
The bolded passage is the slide from something I understand to something I don't. Our experiences of objects are not the objects (dare I say "themselves"). Yet I can see a point here. What we know of objects must be based on how they appear to us. I part from Kant where he says that all we can know is the experiences/appearances. They themselves show us what reality is and that reality is not limited to what appears, what we experience.I am once again in the same difficulty about how I could know anything about them (sc. objects) a priori, or else I assume that the objects, or what is the same thing, the experience in which alone they can be cognized (as given objects) conforms to those concepts, in which case I immediately see an easier way out of the difficulty, since experience itself is a kind of cognition requiring the understanding, whose rule I have to presuppose in myself before any object is given to me, hence a
priori, which rule is expressed in concepts a priori, to which all objects of experience must therefore necessarily conform, and with which they must agree. — Bxvii
I think that this is glass half-full/glass half-empty. I'm very much inclined to represent human beings as iinter-acting with the world, rather than mastering it. The latter version reminds me too much of the Biblical idea that we dominate the world. In some ways, that seems true, especially these days. But climate change reminds us that we don't.Perhaps, but I think it is the tool, as the means to the end, which actually overcomes the circumstances. It is more proper to say that the means is what brings success rather than the will. If it was just the will, you could will yourself to success. Instead, success is highly dependent on the tool employed. — Metaphysician Undercover
I don't know whether a complete catalogue of possible mistakes is possible. Perhaps it is."Mistakes in producing or choosing the symbol to be used as a representation". That would be a mistake of trying to use the wrong tool. We were talking about the different types of mistakes which are possible, and whether each type could be recognized. — Metaphysician Undercover
Of course, there's "know that .." and "know how ..". I'm not sure about "know of..". Perhaps knowledge by acquaintance as well?There's know that and there's know how. Sometimes it's know of. In some cases, it might be a combination?
I know how you feel.
You should know better than to eat wild mushrooms.
I didn't know which path I should take.
I want to know what it's like to jump from an airplane.
How do the migrating butterflies know the way to Mexico?
I love you more than you'll ever know.
Frank doesn't know his ass from a hole in the ground.
I don't think it's really necessary to build a formula for each usage. Do you? — frank
Yes. I can see that you are sceptical about the point of philosophy and it is indeed doubtful. However, rationalizing what life already does is what philosophy does best, it is does anything at all. Compare Augustine on time.We don’t need epistemology to know; epistemology is an after-the-fact rationalization of what life already does. Epistemology is like a priest arriving after the festival, declaring rules for the dancing that already happened. — DifferentiatingEgg
The fact that they do it is powerful evidence that they do know what they're doing. Perhaps one day we'll understand how they know the route . But it's not impossible that we might come to the conclusion that the butterfly doesn't "really" understand or know what it is doing or why. It's a very limited bit of know-how - not the same as understanding how to navigate the world. Compare migrating wildfowl which are rather less limited and more flexible.This is what to me the butterfly question, for one example, would most likely addresses: how does a butterfly (granting it is in some way sentient even though not sapient) behaviorally understand how to navigate their way toward Mexico. — javra
It depends what you mean by "shared". We can both understand how to drive a car, even though I cannot understand on your behalf, nor you on mine. It's a bit like eating in that respect.[JTB type of] Knowledge is always in terms of concepts and can be passed on by means of words or other symbols. Understanding is not conceptual, and therefore cannot be passed on. It is an immediate experience, and immediate experience can only be talked about (very inadequately), never shared. — https://www.anthologialitt.com/post/aldous-huxley
I don't see any reason to suppose that list is complete. But much depends how you distinguish a species of knowledge from knowledge of different kinds of subject-matter.I’m very curious to see if anyone can discern any other species of knowledge via the way “to know” is used within language that would not fit into any of the three categories just mentioned. (I haven’t yet found any.) — javra
You are right about that. Partly, the flexibility is the result of the flexibility of justification which is "played" in different ways in different language-games - just as winning is differently defined in different games. But I think it is most at home in the context of "know that.."JTB is fits into many different language-games, and the definition is based on Wittgenstein's family resemblance idea. — Sam26
In general, that's right. It depends on the project. But sometimes the aim of the project is truth, so in those cases mistake does imply the (possibility of) truth.I don't think so. First, i didn't say anything about how mistake would be determined, only that we ought to believe it is possible. Then, when we look at the primary feature of determining mistakes, mistake is commonly a matter of not producing the desired result. This doesn't imply truth or lack of truth. — Metaphysician Undercover
H'm. But it is odd to say that the tool masters the circumstances. I always thought it was the user who mastered the circumstances by using the tool. But isn't there a case for describing the tool as adjusted to or fitting in with the relevant circumstances. A carpenter's saw is good for cutting wood. For metal, you need a hacksaw. Hammers for nails (appropriate in some circumstances). Screwdrivers or spanners in others. Certainly, the enterprise is to adjust circumstances in certain ways; but one needs to recognize what can be changed and what can't.I think there is a relationship of mastery, like a tool masters the circumstances it is applied to, to produce the desired end. The representation (symbol) is a tool, the living being uses it, and this tool assists the being in survival, as well as making use of its environment toward its ends, and perhaps some other things, dependent on intention. — Metaphysician Undercover
That is much more helpful. At least, I seem to be able to get my head round the argument. I wasn't much impressed by the analogy with Copernicus, however. Yet it is an ingenious thought. Maybe there is some sort of parallel. On this reading, my doubts focus on his "a priori" and especially the requirement that the a priori tells us something about the objects in the world. However, I'm delighted to learn that there are objects in the world and that we can know something about them. Some wires may have got crossed between here and the belief that we only know phenomena (are phenomena objects in the world, I wonder) and we cannot know anything (much) about objects or being in "themselves" (unless objects (being) in themselves are not objects in the world.Kant's terminology is intimidating. I think the way Kant speaks in the Preface to the Second Edition is a good outline to his intentions and what he means by experience, intuition, and cognition: — Paine
OK. Then can you tell me anything about the other meanings?I think it's just an expression of one of the meanings of "knowledge." — frank
Yes, we are agreed about that. But now, what is my body, and what yours? How do we tell the difference> I think that it is implicit in what W says that my body is what I feel pain in and your body is what you feel pain in. Where I feel pain becomes a criterion for distinguishing my body from the rest of the world. (Not the only criterion - there's the possibility of a criterion along the lines of my body being what I am in control of, or what I directly control. But it is more complicated that the pain criterion.)I agree there is an important difference that my pain is in my body, as in: not your body, but also that it is “mine”. — Antony Nickles
I think that's exactly right.Plus, he seems to believe that it is true (we could), only to better understand what the skeptic wants to deny. — Antony Nickles
Yes. It gets confusing, doesn't it? At one moment we are saying "I know your pain" because we've had an injury like that. The next we are saying "You can't know my pain" because you can't feel it. It may be that there is no truth of the matter, that the illocutionary force attached to each is the real point.But to say “I know your pain” is not to try to equate ours, but to identify with you; to say “I feel your pain” is to console you. So then the context of saying it is “impossible” might be in the sense of giving them the space to be alone in their pain, — Antony Nickles
This is the puzzle he leaves us with. I wish I could work out what a philosophical, as opposed to a psychological, approach to it might be.But perhaps this does not “fulfill” what he wants, which is to “try to find the form of expression which fulfills a certain craving of the metaphysician which our ordinary language does not fulfill and which, as long as it isn't fulfilled, produces the metaphysical puzzlement.” — Antony Nickles
That's quite a tall order. But still, if they can all be determined as mistakes, it follows that there must be a truth of the matter, beyond appearances.the different types of mistakes which are possible. — Metaphysician Undercover
That tells me a lot about what you mean by "representation". You don't mean that the representation is similar to or resembles or looks like its object. So now I need to know what kind of relationship you think there is between the representation and what it is a representation of.Suppose that we consider words as an example of a representation. — Metaphysician Undercover
Do you mean what I would call an experience? Something that one might be "directly" aware of? Are you gesturing at a "raw" (uninterpreted) experience? I don't see how anything like that could become a table or a chair. I do think that Kant's point about appearances apply also to experiences - they are always experiences of something; it seems obvious that the object of an experience cannot be the experience, but also experiences cannot also be objects of experience. This is really quite bewilderning.I figure a representation happens when what is given through sensible intuition becomes an object one can have knowledge about: — Paine
You are right. It makes a lot of difference what the context is. My apologies if someone else has responded while I've been away.Possibly I also haven't been clear about why the PoV matters -- who is doing all this. The phrase "point to" is meant to raise this question. — J
JTB amounts to a procedure for working out whether some random belief is actually knowledge. It's not exactly a discovery procedure for knowledge, because the belief needs to be given - unless it is actually a hypothesis.I think you've been assuming, in this discussion, that a single person is taking all these steps, but there's nothing in JTB that requires that. We don't ask, "Have I verified that this sentence is true?" but rather "Is this sentence true?"; we don't ask "Have I provided good justifications?" but rather "Are there good justifications?" — J
I'm all for paying attention to how "know" is actually used. But it may not be easy to discern a single, consistent use, or uses may be different in different contexts. There are some common uses of "know" that, I think, philosophy needs to discount. If I place a bet on an outsider in a race, and exclaim "I knew it would win", it is a rhetorical use of little interest to philosophy. At most it expresses the subjective certainty of the speaker. I don't see that little tidying up for philosophical purposes would go amiss.JTB wants to pin down the correct use of "I know"; I'm suggesting that it might be more profitable to look at the ways we actually use "I know." I don't think they correspond to JTB. There are many things I believe I know, but am not certain they are true. JTB would argue that, therefore, I'm using "know" incorrectly. Whereas I'm saying that it's JTB that needs correction, not me. This latter position lacks punch, of course, unless the "me" can be turned into "us" with sufficient frequency. We need a fairly widespread agreement on the faults of JTB in order to claim that it doesn't capture our common practice. — J
OK. So what's your alternative?So the bridge from practical refutation in everyday life, which often involves the testing of individual hypotheses under the assumption of true auxilliary hypotheses, doesn't withstand skeptical scrutinty and the standards demanded by scientific epistemology - an essentially unattainable standard, relegating JTB to the realm of the impossible, or to the realm of semantics that is epistemically vacuous. — sime
Adding another clause to JTB just to ruling out mimicking or parroting seems a bit over the top. What is much more important is to recognize the importance of the competence of the knower, as you do, of course.On the first point: understanding is not the same as justification. Justification is the giving of reasons that satisfy the standards of a language-game. Understanding is a matter of concept-mastery, the ability to use terms correctly within that grammar. A student can repeat reasons in a way that looks justified, but without grasping the concepts, they do not understand—and so they don’t know. The “+U” is needed because justification can sometimes be mimicked or borrowed without genuine uptake. — Sam26
Well, I would agree that we presuppose that the framework is sound. But I don't think they are necessarily set in stone and they may need to be modified.The framework is sound; what fails is our use of it. — Sam26
Perhaps not. But if truth was not at least compatible with reproduction and survival, we would surely abandon it or die out. Though some events in the world make me wonder whether that is the case and how committed most people are to truth. Perhaps truth is not as important as we philosophers like to think it is.The structure of BT by itself does not seem to get around the problem that fitness vis-á-vis reproduction/survival does not seem to necessarily track with truth. — Count Timothy von Icarus
Kant is right to emphasize that appearances are always appearances of something. But he does not press the consequences of this observation. It sets up a close relationship between appearance and reality and undermines the idea that appearances are entities that exist independently of what they are appearances of. It even suggests to me the somewhat surprising possibility that appearances are, or at least can be, what reveal reality to us, rather than concealing it.But later, he's saying we must pre-suppose them (despite, not being able to know them). — AmadeusD
"Difficult" is a very mild description for this situation. It suggests that you think that "representation" is not really an inappropriate concept to apply here. But you also (seem to) accept that there is no real evidence for such an object "in the unexperienced bush". So I'm rather puzzled what to make of this.Deciding what is a mistake in Kant is more difficult. We don't have the object of representation in hand to compare with another supposed object in the unexperienced bush. — Paine
It's hard to disagree with that. But if we accept that possibility, should we not, by the same token, accept the possibility that there is no mistake. We could then ask which of those possibilities is actually the case. Or even question the framing of the question.Instead of insisting that there must be real independent objects, because we perceive objects, as Amadeus seemed to be doing, we ought to accept the possibility of mistake. — Metaphysician Undercover
That makes a lot of sense. But you seem to me to be giving with one hand and taking back with the other.Perhaps I'm not grasping this, but if someone is perceiving "something" then that is "objects" broadly (and in the way i suggest it be used here - I'm not suggesting there are (or that we could know that there are) actual, physical objects beyond the senses). These could simply be that which is required as an assumption for hte perception to obtain. I content roughly that. — AmadeusD
It's fascinating to see how W moves from distinguishing between the "common-sense philosopher" and the "common-sense man" to discussing the argument between realism and idealism and back again. There's a web of distinctions and differences here which is extremely difficult for philosophy or philosophers to negotiate. But getting caught up in it seems completely pointless. The last sentence is what's important.Now the answer of the common-sense philosopher--and that, n.b., is not the commonsense man, who is as far from realism as from idealism--the answer of the common-sense philosopher is that surely there is no difficulty in the idea of supposing, thinking, imagining that someone else has what I have. But the trouble with the realist is always that he does not solve but skip the difficulties which his adversaries see, though they too don't succeed in solving them. The realist answer, for us, just brings out the difficulty; for who argues like this overlooks the difference between different usages of the words "to have", "to imagine". "A has a gold tooth" means that the tooth is in A's mouth. — p. 48/49
I had a lot of difficulty about this. Perhaps it's an example of what you talked about earlier - Wittgenstein considers some very extreme examples, because he wants to give his opponent all possible rope - explore the remotest possibilities.Suppose I feel a pain which on the evidence of the pain alone, e.g., with closed eyes, I should call a pain in my left hand. Someone asks me to touch the painful spot with my right hand. I do so and looking round perceive that I am touching my neighbour's hand (meaning the hand connected to my neighbour's torso). — p. 50
His conclusion is all right. But I'm not at all sure that the path to it is secure. It is all very well to say that one needs to understand an order before being able to obey it, but "before" here is not a temporal "before". (You are quite right to put "beforehand" in scare quotes.) The understanding and the ability to obey are one and the same thing - inseparable. Obeying the order correctly is one of the criteria for understanding it.He decides that these are cases where we must be aware of something before we could judge what is the case, as in needing to understand an order before being able to obey it.
A peripheral case that does not appear to fit the above “beforehand” necessity is “I must know where a thing is before I can see it” (p.50) perhaps because I would be told what it is, not where, and then I would search for it and know where it is in the seeing of it. After seeing how these cases work completely differently, he makes the leap to postulating that “What I wish to say is that the act of pointing determines a place of pain.” — Antony Nickles
That's circular. You can only satisfy the JTB if you know that X is true.we can deduce, from the fact that we have JTB of X, that X is true. — J
That is indeed a problem. But we can't solve all the problems at the same time. For the purpose of defining knowledge, we can assume that we have a concept of truth and worry about what it is on another occasion.My concerns with JTB are all about how the truth of P is supposed to be established — J
Well, that seems a bit radical. Most people, I think, believe that knowing at least the outline of the truth-conditions as part of understanding the meaning of what one is signing up to.If you tell me, "I know X, because I have JTB of X," and I believe you, then I know, or at least believe, that X is true, without knowing anything about its truth conditions. — J
So you accept knowledge based on authority. I'm a bit surprised - it is quite unusual for philosophers to accept that. They usually, if only by implication, seem to believe that only first-person verification is satisfactory. That's a very strict criterion and cuts out most of what we (think we) know.Is personal verification of the truth conditions the only truth-guaranteeing justification? Or, if "guaranteeing" is too strong, the only good-enough justification? — J
That's fantasy, not a real possibility. On the other hand, the possibility that one of our superpowers will make that decision and actually try to do it. That's a real possibility.An alien civilization inimical to ours might choose tonight to destroy our solar system. That is not impossible, or incoherent, or against the laws of physics, etc. — J
I'm a bit puzzled about you are getting at here. It's my move in a chess game. I have various possibilities with the rules. Many of them have little or no strategic or tactical value. I decide on one and make it. All the other possibilities are ruled out. They were possibilities, but are no longer. Similarly, when I set out to decide whether P, there are (barring complications) two possibilities - that it is true, or that it is false. If I decide (correctly) that it is true, then the other possibility is ruled out.Doesn't that have to answer the possibility question. If P is true, it cannot possibly be false. — Count Timothy von Icarus
I don't think we have to develop our understanding of knowledge to be compatible with every theory of knowledge. If we are not committed to a theory, we take for granted our existing concept, whatever that may be. It we are committed to a theory and it makes a difference to the epistemology, then, of course, we need to take it into account.What sort of concept though? Rorty's move to redefine truth as "what our peers let us get away with is a conception of truth. — Count Timothy von Icarus
For me, the question whether P is true and the question whether I think that P is true are the same question - or rather, the answer to whether P is true determines whether I think that P is true. Something similar would apply to a question whether we think that P is true.Rather, it is, do we think P is possibly false. — Count Timothy von Icarus
Quite so. Asserting P is a speech act, and it has various effects, which are usually called forces. The standard taxonomy has three, as I'm sure you know. The difficulty is to utter P without some sort of illoctuionary or perlocutionary force. The ground for thinking that the content is distinct from the ancillary forces is that we can utter the same proposition with different illocutionary forces. We can assert, deny, suppose, know, believe and think that p.Affirming P is a sort of endorsement. "It is good to believe P," where "good" is also "hurrah for..." — Count Timothy von Icarus
Yes. Though that formulation of the point leaves open the possibility of claiming special status for the theoretical context that is philosophy. It is probably better to point out that such sceptical beliefs have no significance.No matter how hard they reasoned about the groundlessness of their own knowledge, they would still run from rabid dogs like Pyrrho or climb a tree to get away from raging bull elephants like Sanjaya. — Count Timothy von Icarus
Knowledge of what one will do later in the day is not quite the same as having intentions or plans for what one will do later.Hence, in most ordinary circumstances, one will affirm knowledge of what one will do later on in the day (or else of when one’s airplane will arrive), this serving as one example among many. — javra
There is no safe side. One may prioritize avoiding believing something false, but that raises the risk of failing to believe something true. Both are wrong.If one instead prefers to remain on the safe side, one can instead simply declare it as a belief one has. — javra
OK. You know where I stand on Gettier. Though I would like to add that the analysis I gave earlier of his case 1 is not a model for other examples. The point of attack is the same, but the analysis has to be worked out in each new context.I think there is a problem with this account, and I think the problem is precisely what Gettier points up. Gettier shows that someone can have belief, truth, and inconclusive evidence, and still fail to have knowledge. (But I am going to come back to your earlier posts in this vein. I am still catching up.) — Leontiskos
No, of course. Though as Hume points out, you are going to believe that you will succeed next time because you have succeeded before. Who's to say that's wrong, given that deductive logic doesn't apply.Hume would say that even if you've pocketed the 9-ball in this identical situation 1,000 times in the past, it doesn't follow that you will pocket it this time. — Leontiskos
If that's what Aristotle or Aristotelians say, I can see a certain sense in it. But there is the tricky problem how I avoid being burnt to a crisp by the sun.if the identity of mind and object is true, then you do not have global uncertainty. — Leontiskos
You may well be right.What is at stake here is an argument against truth dressed up as an argument against JTB. — Leontiskos
I do accept that there may be some qualifications and caveats and that it seems very hard for fallibilism to escape from the problem that we can't be said to know p if p is false."I know that I know ..." is pure pleonasm
— Ludwig V
Upon reflection, I think you might be right (at least in the JTB context that isn't committed to fallibalism). — Count Timothy von Icarus
To be honest, those kinds of fallibilism seem incoherent to me. Something that might be false may in fact be true. To put it another way, the possibility of p being false seems to me to be irrelevant to the question of knowledge. What is relevant is whether p is or is not false, on the assumption that if it is not false, it is true.However, if we pair JTB with a sort of fallibalism that denies any certitude to beliefs, ... I do think it follows that we can never know that we truly know anything. .... Another way to say this is that, if we believe our own belief might be wrong, we don't seem to believe that we know it, since knowledge is necessarily true, and we can hardly believe that something that is true might also be false. — Count Timothy von Icarus
In one way, you are pushing at an open door. "Know" is one of a large group of terms that express an attitude to, or an evaluation of P. But such an approach would need to include assertion as part of their meaning, as well as an attittude towards what is asserted. But it's very complicated. "Know that p" includes an evaluation of p as true, so it indirectly asserts p. "S thinks that p", on the other hand, includes an evaluation of p as false and therefore denies p. Supposing that p is more complicated; it doesn't assert or deny p, but asks to treat p as true (usually for the sake of an argument. And so on.One solution here, that I'm sure no one will like, is to simply do what analytic philosophers have done for "evaluative" knowledge claims. We could suppose that statements of knowledge and statements of fact should simply be reinterpreted the way evaluative statements are, such that: "P" is "hurrah for asserting P!" or "I believe P," or "from my perspective, P." — Count Timothy von Icarus
Well, my approach would be to explain that certainty and doubt, possibility and impossibility, etc. are meaningless without a concept of truth.... it's on us to show why we think there needs to be something of the sort where "P is *really* true," and that we must be able to assert that this is so.. — Count Timothy von Icarus
You are treating those philosophical ideas as if they are true or make sense. If they don't make sense, we need not bother with them when defining knowledge.After all, others' first-person experiences and beliefs are generally accepted to be ineluctably private, so prima facie there can be no empirical support for them, whereas there can be no empirical support for anything outside of such experiences for us. — Count Timothy von Icarus
But we don't know that X is true via JTB, but via whatever the truth conditions are for X.If it's right that we can't know X is true via JTB (since it's an element of JTB, not a result, and would require a previous demonstration of knowledge), then we might never know whether we know a given X, since we wouldn't know if X was true. — J
This is a false dilemma. John's subjective truth will be conditioned by his understanding of what mathematical truth is, which he has learnt through interaction with others who teach him. Unless that has happened John may have a subjective opinion, but it doesn't count as a mathematical opinion.So we have two distinct notions of truth in play: Intersubjective mathematical truth, for which the truth maker is independent of Johns judgements whether or not his judgements are correlated with intersubjective mathematical truth, versus what we might call "John's subjective truth" in which the truth maker is identified with the neuropsychological causes of John's utterances. — sime
Sure. He also has to live with the possibility of being right. But he can live with neither possibility unless he knows what it is to be wrong - or right.John has to live with the possibility of being wrong. — frank
OK. Is there any activity that you see as a non-physical activity? Unless there is, you've deprived "physical activity" of its meaning.I see doing mathematics as a physical activity, involving pencil and paper, computer, or neural activity. — Janus
There is a difference between the possibility something might not be the case and it actually not being the case. You are treating mere possibilities as if they were actual.If say I am certain that something is the case, then I mean that there cannot be any doubt about it. Then I would say I know it to be the case. If I think something is the case but there is any possible doubt it, then I would say that I believe it to be the case, but do not know it to be. — Janus
That seems reasonable. I'm still doubtful about your "small possibility".Say I believed that something is the case, and for very good reason, despite thinking that there was some small possibility which could cast a doubt about it—then I would say I believed it, but did not know it, to be the case. Then say I found out that the small possibility of doubt had been unfounded—I would then say I now know it to be the case. — Janus
Why? Where does it say that it is not possible to know something but not to know that you know it? It isn't like a pain or a taste, where what I say determines the truth. I suspect that you are thinking of the first person "I know that I know..." But it is perfectly possible for me to say "Janus knows that p, though he thinks that he believes it."But if I had justifiably believed it to be the case previously, despite thinking there was a small possibility of doubt and the small possibility of doubt turned out to be a mistake, then according to JTB I would have already known it to be the case despite the fact that I didn't think I knew it to be the case. That would be knowing despite not knowing that you know. And that just seems weird to me. — Janus
No, you are quite right. Justification and investigation are how we determine the truth.an objection to any theory which says that truth is supposed to be established prior to justification and investigation, — Leontiskos
The issue here turns on justifications that provide evidence, but not conclusive evidence. In the context of JTB, such justifications can work, because the T clause denies claims to knowledge based on partial justification when their conclusions are false.In seeing an unsound justification and a sound justification as equivalently sufficient conditions for knowledge. — Leontiskos
Yes, if the justification is not conclusive - i.e. not sufficient.Can the justifications for thinking it true be themselves true even if the theory is false? — Janus
