But what would it mean that you wouldn't necessarily end up doing what you intended if not that there was some other necessary condition that prevented you from doing it? If there were no other conditions preventing you from doing it, wouldn't you be doing it? If not, then you never intended to do it in the first place. Do any of your posts appear on this screen without you having intended to post them?Wanting to does not mean I have to. Intending to does not mean I would necessarily end up doing what I intend to do. — Fooloso4
How would you know what is possible if everything that is the case is an accident? What is not the case isn't necessarily possible. What is not the case is just as much probable as improbable, because you have no evidence to support the probability nor improbability. There is no evidence for what is not the case. So if what you mean by "logical space" is "imaginary" then I guess we agree.What is not the case exists in the logical space of what is possible. Logic is transcendental. It makes possible not only states of affairs but the possibility to think of states of affairs. We cannot think illogically — Fooloso4
Not at all. You recognize entities, like your pet or your friend, by their pattern of properties - patterns of sensory properties - their color, shape, the sound of their voice, the feel of their touch, their smell, etc., just as you are able to distinguish between coffee and water, but the pattern of color, smell, taste, etc.Entities are patterns of properties.
— Harry Hindu
At a stretch. Ok. If mental entities include linguistic conventions, then no one counseled dispensing with them. — bongo fury
but it does exist as a phenomena of your imagination and your imagination is just another fact of the world, or what is the case.Note 'extraspatiotermporal' which in plain language means 'not in time and space'. So these kinds of 'objects' are not existent in the sense that phenomena are existent, as phenomena exist in time and space. — Wayfarer
Like I said, they know what the edges are and what is fuzzy.Ok, so in a limited (physicalist) sense you could say that extraspatiotemporal objects are not determinate, but in a general (mathematical) sense they are just as well-defined and hence determinate as spatiotemporal mathematical objects. — litewave
I don't see how you could have shared it if you didn't want to, or intend to.Obviously it happened. It is not, however, necessary that this would happen thought. His notebooks might never have been published. It is not necessary that I quoted him or that I discuss him or post on this forum or that forum exist.
"Wanting to share" is, as you say, something I wanted to do. It is a choice not a necessity. — Fooloso4
It seems to me that whenever anyone uses language they intend to convey information to others. The fact of the matter is the relation the speaker or writer has between the sounds and scribbles they make and the idea they intended to convey. What that might be is anyone's guess, but if you speak the same language as the speaker or writer, somehow, your chances of interpreting that relationship is substantially better than if you didn't speak their language. This must mean something, or else I can speak Italian and say that it's Vietnamese without any fact of the matter to stop me - if my intent was to cause confusion. If my intent was to communicate, then it would help to know the language of my audience.What is the relation between language and real, nameable objects? This is the question of the basis of the concept of an object or category of objects. Doesn’t the mathematical determination follow upon the linguistic-semantic determination? Are you assuming that language is referential: we assign a semantic meaning and then associate it with a linguistic token? How do I know that my token means the same thing as your token? Is there a fact of the matter that will settle such disputes of meaning and sense? Do the empirical facts of the world ( or dictionary definitions) intervene to settle these matters? — Joshs
Entities are patterns of properties.Not an entity, that's the thing. A linguistic regularity. A pattern. — bongo fury
"Accident" is not a synonym of unnecessary. "Accident" is not the correct term to convey what you actually mean. So it is necessary to use the appropriate terms if your goal is to communicate your ideas efficiently. It would also seem necessary to learn a language before you can use it. If those are necessary causes for communication to happen then why wouldn't other relations in the world not be causal in the same way? What's so special about language use when language use is simply another process in the world?No. It means that the way things are is not by necessity. — Fooloso4
...a mental entityConvention? — bongo fury
The accidental only makes sense in light of the determined or predicted. Saying that something is accidental implies that there is a way things are supposed to be but something unintended happened that made things different. Accidents only come about when something was predicted to happen but didn't. If you dont make a prediction then there can be no accidents.Thought has a transcendental logical structure. You cannot think illogically (3.03) The relations of simple objects share this logical structure. The movement of tectonic plates is accidental.
6.37 There is no compulsion making one thing happen because another has happened. The only necessity that exists is logical necessity.
6.41 For all that happens and is the case is accidental. — Fooloso4
Language, art, music, etc.

So does science. Science and Philosophy are about things. Is the idea of multiple universes and dark matter in the domain of philosophy or science? Are they mental entities as bongo put it, or something else?If they're about things in the world, they're fine. It's mainly philosophy that tries to comment on the world from a vantage point external to it. — Tate
Depends on the claim. Maybe the issue is saying that you can claim any metaphysical position. Seems that you can only ponder or hypothesize metaphysical positions. A claim would change it from being metaphysical to scientific, no? Are scientific claims nonsense? Why?That metaphysical claims are nonsense. — Tate
If we dispense with mental entities then what is left?That's the kind of reason I (and I claimed also W) counselled dispensing with mental entities.
I was going along with it (entities included) out of interest, while I thought I could follow. Awareness too, and I'm out of here. — bongo fury
And then lost traction when science discovered that the world is not as it appears and that observers might actually influence what is observed.It gained traction with advancements in the natural sciences which heavily depended on observation and repeatability as a ground for establishing fact verses hypothesis or beliefs. — Benj96
So physicalism, materialism and naturalism are concepts. How are concepts physical, material or natural? How do physical things and concepts interact, or how do physical things come to possess concepts?To my mind, methodologically speaking, materialism (facticity, data) is a subset of physicalism (modeling) which is subset of naturalism (explanation). — 180 Proof
Sounds circular. What does it even mean for a concept to be physical vs. Non-physical? Are you talking about the ontology of concepts, or what the concepts are about? If the latter how do concepts come to be about anything? Is aboutness physical or non-physical?As a metaphysics, it's arbitrary, even scientistic. However, as a methodology (criterion) for eliminaing "nonphysical" concepts from the construction of explanatory models of phenomena, physicalism is demonstrably more useful than any non/anti-physicalist alternative. — 180 Proof
Everyone examines their lives at some point - usually in the late teens - early twenties. They question their existence and their purpose. The real question is how much of an examination does your life need before you can get on with just living it? Philosophy seems to have shown that you can never know anything, or that you have to start with some assumptions. So it would be pointless to keep asking questions for which you will never get an answer.Interesting argument. I didn't ask or answer any such questions in 4th grade. I think most of us live unexamined lives, derive value systems unsystematically through experience and socialisation, holding onto views that are an amalgam of fallacies, prejudices and models of reality which can't be justified. I think the point is ignorance is bliss, truth seeking doesn't ususally make any real difference to survivability or prosperity and people have no idea how much of what they think is deficient. — Tom Storm
Philosophers are the ones that don't seem to realize that as they attempt to re-ask the same questions we asked and solved in the 4th grade.
— Harry Hindu
What are those questions? — Jackson
They weren't cherry-picking past usage. Read your sentence again. They were re-purposing words, which are scribbles and utterances, for new usages, just like we re-purposed bumps to use as words as braille, and arm and hand movements as sign-language.When we agree on new uses for a term we are essentially creating a new context with which we use the term.
— Harry Hindu
Sure. Cherry-picking cases of past usage that help to sell our new theory.
Weren't Newton & co. rather cheekily re-purposing psychological words like force ("courage, fortitude"), inertia ("unskillfulness, ignorance"), moment ("importance")? — bongo fury
Sure, there are some uses of language that appear to be habit more than a clear understanding of what it actually means to say such things, but I've seen philosophers fall prey to the habit just as much as ordinary people. Assumptions make up the the foundation from where we build our understanding of the world. Philosophers are the ones that don't seem to realize that as they attempt to re-ask the same questions we asked and solved in the 4th grade. That isn't to say that there aren't some higher level assumptions that we take for granted that can't be questioned - like does God exist - but then ordinary people can be just as concerned about whether god exists (like when they are suffering at the hand of an unfair world) as a philosopher can.To finish the preface: the philosopher believes that the ordinary person is either unfamiliar with the distinction or fails to apply it properly, and that if they did they too would be in the pickle philosophers are, unable to bridge the gap. Most people just don't notice, or don't understand what a big deal this is, that's the mantra of philosophy. (The other example that leaps to mind also comes from Hume: how do you know the sun will rise tomorrow?) — Srap Tasmaner
Speak for yourself. :smirk:Philosophers: Ordinary folk think too less.
Ordinary folk: Philosophers think too much.
We never hit the sweet spot betwixt deficiency & excess now do we? We're always swinging, pendulum-like, back and forth between extremes. The aurea mediocritas isn't easy to either attain or maintain. — Agent Smith
Depends on what you mean by "proposition". Propositions can be ink marks on a piece of paper, or vibrating air molecules when speaking.But a material object cannot literally be a part of a proposition and therefore cannot be part of a fact. — Art48
I don't get this distinction between everyday, ordinary usage and some other usage. Usage depends on context. Why should we consider a philosophical context any different than any other context? The idea of ordinary usage takes into account these various contexts. What is ordinary about the usage is that it is ordinary to use the terms that way in those contexts. Any unordinary usage would be a misuse of terms in that context. When we agree on new uses for a term we are essentially creating a new context with which we use the term.In everyday usage, sure. — bongo fury
Just another way of saying that it is a misuse of language.Clearly an absurd conclusion. — Andrew M
Yet you did assert that you know when you didn't with ordinary usage. You just know something different now.There isn't an epistemic difference (i.e., either way, one is correct or mistaken about whether it is raining). However there is a semantic difference. With the "knowledge changes" position you can know it is raining when it isn't, on ordinary usage you can't. — Andrew M
As I already pointed out, you being mistaken is good evidence that you can still be mistaken with any knowledge claim, which is to say that you can never know that you know. So thinking of knowledge as a changing interpretation based on new good evidence resolves the issue. There can be right and wrong interpretations. A wrong interpretation is not no interpretation, just a different one based on the good evidence one had at the time. Given that evidence you had at the time, it would be a valid interpretation. So either we make knowledge a synonym of interpretation or we just omit the word from usage because it would be useless. Using knowledge as a synonym for interpretation is how we use the word in ordinary usage anyway when we take into account how we used the term, "knowledge" in the past as well as now when we say we know but can't know that we know thanks to the good evidence that our interpretations have changed in the past.If you want to know whether it is raining then looking out the window provides good evidence. You can say that you know it, but be mistaken, as with any claim. You can also know that you know. That's just how the logic of the usage plays out. As mentioned, the standard for claiming knowledge isn't Cartesian certainty. So its possible to think that you know that you know when you don't. — Andrew M
Which addresses my question that I asked before about how many observations need to be made before we can claim knowledge which you responded:You could be wrong again and again. But that's unlikely for a given case, since you require good evidence for each iteration of the claim. The space of possibilities rapidly diminishes. Consider what it would take to be wrong that the Earth orbits the Sun. — Andrew M
How would you know that the space of possibilities "rapidly diminishes" without knowing how many observations need to be made? You are claiming to know something that you couldn't possibly know or else you would have made the correct interpretation in the beginning if you knew how many observations you needed to assert knowledge.But "every possible observation" is not the standard for making knowledge claims or forming beliefs. — Andrew M
Which is to say that the interpretation we had was valid given the reasons we had at the time. Our interpretation can change, but that doesn't mean that we never had an interpretation in the past.It can be a good reason at the time. It may no longer be a good reason in the light of new evidence. Also there need be no infinite regress, as suggested by the orbit example. At some level of evidence you expect to converge on the truth. — Andrew M
Which is the same as saying that it was a valid reason for arriving at that interpretation. Knowledge claims can be made if we define knowledge as an interpretation (which I have already shown that the ordinary usage of knowledge is a synonym for interpretation). So we do have interpretations/knowledge. What constitutes good reasons for one interpretation does not qualify as good reasons for a different interpretation. If you become aware of new evidence then you amend your interpretation. This doesn't disqualify that looking out the window is good evidence for interpreting that it is raining. Most of the time it is, and still is even though you were mistaken once before.It is good evidence. If it weren't, then essentially no knowledge claims could ever be made (as Descartes discovered). Yet we do have knowledge. However what constitutes good evidence at one time may no longer be sufficient in the light of new evidence. If you become aware that your brother sprayed the window, then you retract your former claim, since the fact that you looked out the window is no longer a good reason to believe it was raining (though it was a good reason before). — Andrew M
As if Wittgenstein is the prophet of propositions. :roll:Read Wittgenstein’s Philosophical Investigations. — Michael
Which is to say that we have definitions of life that allow us to distinguish it from things that are not alive. All I'm asking is what those distinctions are. If you can't even answer that simple question then it does not follow that a chicken is not a proposition. A proposition could be anything, which makes your arguments non-sensical.What is life? I know that I’m alive and that a rock isn’t. But there’s no proper understanding of what life is, with over a hundred proposed definitions. — Michael
What is a definition if not the suggested, or commonly understood way of using the term? What you're saying is that you don't know how to use the term, proposition, so it doesn't follow that you can know how they relate using formal logic.I said I can't give you a definition of "proposition", just as I can't give you a definition of "number". But I know which things are numbers, which things are propositions, and which things are neither.
And I know that 2 + 2 = 4.
And I know that modus tollens is a valid rule of inference.
And I know that chickens are animals.
That's all that matters for this discussion. — Michael
That's not necessary. You've already shown that you have no idea what you're talking about, which is the point I was trying to make. Thanks. :smile:I can't give you any meaningful definition of "proposition", just as I can't give you any meaningful definition of "number". I can give you examples of things which are either numbers or not numbers, and examples of things which are either propositions or not propositions.
But, again, this has nothing to do with Fitch's paradox. If you want to talk about what propositions are then start another discussion. — Michael
I wasn't asking for an in-depth metaphysical understanding of the nature of language. It's not necessary to answer a simple question. You said, "I don't know". I'm just asking for a simple definition of "proposition". What do you know, if anything, of what a proposition is? You have to have some understanding of the nature of numbers to do maths, or else what are you doing when you do maths?. :roll:I don't need to have some kind of in-depth metaphysical understanding of the nature of language and reasoning to make use of formal logic, just as I don't need to have some kind of in-depth metaphysical understanding of the nature of numbers to do maths. — Michael
You keep using this term, "proposition" that you've you admitted to not knowing what they are. If you don't know what propositions are, then how can you even know what kind of relationship exists between them? You just continue to post scribbles on this screen and asserting that there is a relationship between them, but don't know what the members of that relationship actually are.Formal logic is concerned with the relationship between propositions. — Michael
Which isn't any different than saying knowledge is an interpretation that changes with new evidence - not that you never had it.We don't. But "every possible observation" is not the standard for making knowledge claims or forming beliefs. Good evidence is. If good counter-evidence emerges, then we should change our minds and retract the former claim. — Andrew M
Yet we asserted that we did know and were wrong, which is good evidence that you could be wrong again, and again, and again - hence no such thing as knowledge unless we define knowledge as an interpretation that changes - not that you never had it. So, using your "good evidence" definition, you have good evidence that you can't ever possess good evidence. Your argument defeats itself.You can look out the window at the moment your trickster brother sprays the window with a hose.
— Harry Hindu
In which case you wouldn't know it was raining, you would just think you did. — Andrew M
As I pointed out, it is very possible that your good reason or evidence isn't actually a good reason or evidence, and you only find that out after you get good reason or evidence, yet it is very possible that your good reason or evidence isn't actually good reason or evidence, and you only find that out...,etc. It's an infinite regress.Is it possible to believe a truth? How would that be different than to know a truth?
— Harry Hindu
Yes. To know it also requires good reason, or evidence, or justification. — Andrew M
No. It is you that assumes a standard of infallibility or Cartesian certainty by saying that "good evidence" is what is needed to possess knowledge. I'm simply asking you to define what that means, if not that "good evidence" is a state of infallibility (knowing the truth). I already pointed out that looking out the window is not good evidence because your brother could be spraying the window with a hose.How do we ever know that we have all the evidence necessary to assert knowledge over belief?
— Harry Hindu
Your question assumes a standard of infallibility or Cartesian certainty. But you can say that you know it is raining (or not) by simply looking out the window. That's the relevant standard for making knowledge claims. — Andrew M
This is circular.Another way to think of this is in terms of Ryle's achievement verbs. We can believe or claim that it is raining and be mistaken but we can't know that it is raining and be mistaken, since to know that it is raining is to be correct and for good reason (e.g., we looked out the window). — Andrew M
But this misses the point that what we used to call knowledge wasn't knowledge in light of new observations, but observations is what allowed us to assert knowledge that we didn't have in the first place. So how do we know that we've made every possible observation to assert we possess knowledge? Seems to me that either knowledge is not related to truth as Michael's non-omniscient principle seems to state:Indeed, and that's the point. When we discover that a former knowledge claim was mistaken, we retroactively downgrade its status from knowledge to belief. We say that they didn't know it after all, since we no longer believe that it was true then. — Andrew M
or "knowledge" is a useless term and we can only ever believe our assertions.some truths are unknowable — Luke
But A does not say either way. B tries to clarify the distinction but fails whenIn practice it may be that asserting a proposition implies that one believes one's assertion (see Moore's paradox), but in formal logic there is a distinction between asserting that a proposition is true and asserting that a proposition is known to be true. — Michael
It seems to state that knowledge and truth are not related.The non-omniscience principle states — Michael
You don't understand the question, what is knowledge?I don't understand what your comments have to do with anything. — Michael
But one has reasons to believe alien life exists and that it will rain tomorrow. What reasons does one have to know that know one knows alien life exists or that it will rain tomorrow?I might believe it to be so? e.g. alien life exists, the real part of every nontrivial zero of the Riemann zeta function is 1/2, it will rain tomorrow. — Michael
It seems to me that b renders a as a meaningless string if scribbles.a the cat is on the mat
b nobody knows that the cat is on the mat
Both a and b are true. This means that, even though a doesn't say so about itself, a is an unknown truth. — Michael
I think most of it hasn't been to discuss whether or not an external material world exists, but what everyone means by, "external", "material" and "world". Threads like this tend to go on forever because we are all talking past each other and misusing terms. Some are artfully (not literally) using terms in playing word games and don't seem to have the intention of saying much of anything useful.I am posting this on page 33 of the topic "Is there an external material world?", which is very close to 1000 responses!
I really wonder and cannot believe how could such a trivial and without real value or use --for me, of course-- question, the answer to which is more than obvious,, could arise such a huge interest and create such a huge discussion! — Alkis Piskas
