May I ask which scenario you are referring to: the Russell example or the counter-example? — fiveredapples
declarative knowledge is: true belief that, on account of being true, can be factually justified without end were one to so want and be capable of doing. — javra
In the Russell example Bartricks gives, the man has justification under the JTB conception of knowledge. If he didn't, it would pose no problem for the JTB conception of knowledge. The problem is that our intuitions about knowledge tell us that something is awry. We don't think he has knowledge, pace JTB, and we pinpoint the problem to the source of his belief: namely, the broken clock. There is no human fallibility at play here. To think fallibility is at work here -- to respond that the man made a mistake in thinking the broken clock was a working clock -- is to not realize that the justification criterion, per JTB, has actually been satisfied in the example. — fiveredapples
The Pythagoreans originally insisted vehemently that every number could be expressed as a ratio of two integers, and then someone refuted that by showing that some definitely cannot. Is that refutation not set in stone now, as much as the observation of one black swan forever refutes the claim that all swans are white? — Pfhorrest
if one cannot prove that at no future time will anyone find conceivable what to us is currently inconceivable (say some sapient being that will exist a million years from now) then neither can one demonstrate the infallibility of the claim. We find it impossible to conceive of how the square root of 2 is not irrational; can this of itself demonstrate that all intelligences that shall exist for all time yet to come will likewise find it impossible to conceive of some justifiable alternative to this affirmation? If not, then we have not demonstrated that no unknown future refutation is possible. — javra

Hence, all sound deductive reasoning is less than infallible in its conclusions. — javra
Agreed. — TheMadFool
To be clear, by "capitalism" do you just mean free trade, or do you mean the division of society into a class of owners and a class of laborers? — Pfhorrest
The basic question is: Is logic derived from how the world works or is logic independent and prior to how the world behaves? — TheMadFool
The problem of induction and Popper's falsifiability anticipated. I don't know if it works for deductive logic though. The square root of 2 was irrational before the Pythagoreans deduced it and will always be irrational till the end of time itself. — TheMadFool
As for example, when someone proposes an argument to us that we cannot refute, we say to him, "Before the founder of the sect to which you belong was born, the argument which you propose in accordance with it had not appeared as a valid argument, but was dormant in nature, so in the same way it is possible that its refutation also exists in nature, but has not yet appeared to us, so that it is not at all necessary for us to agree with an argument that now seems to be strong."
Sextus Empiricus — ZzzoneiroCosm
Also the word "refutation" says a lot about what Sextus Empericus meant. It implies a premise or premises will turn out to be false but it's unlikely that there will be a problem with validity. This ties in quite neatly with the problem of induction and Popper's falsifiability doesn't it? — TheMadFool
Does the prospect of a unknown future refutation make the strongest argument weak? — ZzzoneiroCosm
Should it at the very least temper a dogmatic approach to knowledge- and certainty-pronouncements? — ZzzoneiroCosm
Addendum: It's wise to beware (moreover) of an uknown future refutation of the possibility of an unknown future refutation. — ZzzoneiroCosm
Is it possible to refute the possibility of an unknown future refutation? — ZzzoneiroCosm
That is irrelevant if you understand the distinction between the things I labeled “physical/actual” vs things I labeled “abstract/virtual”.
Those are two distinct categories of existence as I described, and you may label them as you wish or think about them whatever you want, but as long as we agree the distinction exists, then the question still stands whether qualia belongs in one or the other category. — Zelebg
As we concluded over the last few pages there are only two possible modes of existence we know of, actual and virtual. Thus the nature of subjective experience, aka qualia, can either be physical or abstract phenomena. — Zelebg
Now, if we can agree with all the above, then the question is what do you think ‘subjective experience’ or qualia is, physical or virtual phenomena? — Zelebg
'I am a liar.'
is already a paradox. Tell me if you know I am a liar or not? — ovdtogt
You're out of your depth. — Bartricks
I do not know what you mean by LNC, or how what you're saying responds to what I have already said about this.
Dialetheism is the theory that there can be true contradictions.
That's not a theory about truth, but a theory about what can be true.
It is consistent with my theory. — Bartricks
You agree with gibberish? What do you agree with? — Bartricks
The correspondence theory of truth is not a substantial theory of truth. It is true - no one disputes that it is true - but it is true because it is trivial. It says "a proposition is true when it corresponds to the facts", yes? — Bartricks
Dialetheism is the position that some statements are both true and false, i.e. that some contradictory propositions express what is termed “true contradictions”. I hold disregard for dialetheism, but the point is that it uses reason to make and substantiate this assertion. Dialetheism stands in contradiction to the law of noncontradiction (the LNC), which also uses reason to make and substantiate its assertion.
If truth is that which Reason asserts, given that reason can assert both dialetheism and the LNC, would both dialetheism and LNC be true?
If they’re not both true, wouldn’t this evidence that truth is not a product of what reasoning asserts? Reason can assert both dialetheism and the LNC but, here, they’re not both true – hence one given which reason asserts is here necessarily false.
Alternatively, if they are both true, then how does this not negate the LNC in favor of dialetheism and, in the process, evidence that truth is not a product of what reasoning asserts? Reason can assert the LNC but, if both dialetheism and the LNC are true, the LNC would necessarily be false as entailed by the true contradiction of both being true – thereby again making something which reason asserts false. — javra
Reason presupposes truth as correspondence by virtue of presupposing the truth of it's premisses. — creativesoul
So, absent some good reason to think otherwise, our working hypothesis should be that truth is a performative of Reason. What it is for a proposition to be true, is for Reason to be asserting it. — Bartricks
Meaning, if the language of mathematics (metaphysical abstracts) is encoded into all of the physical/natural world, what does that infer? To me, it infers that a metaphysical reality exists.
The next question would be here, did that metaphysical truth always exist independently, or did humans invent it(?). Objectively, not sure anyone knows... — 3017amen
Let's take an empirical claim such as: All objects obey the laws of gravity. Notice that it is a Aristotelean categorical statement. Isn't it necessary then to consider the logical character of such statements before we talk of its empirical import? What do you think? — TheMadFool
If a scientific theory is categorically true then it is ontically unfalsifiable and the only way we can know that is to show that it's epistemically unfalsifiable. — TheMadFool
Let me cheat and use categorical logic to show that indeed I am, very surprisingly to me, right.
All swans are white in logic doesn't have existential import unlike its negation: Some swans are black which can only be true if and only if there is at least one black swan.
Lacking claims of existence the proposition: All swans are white, is true even if you never saw a swan let alone white swans. I think in predicate logic the statement gets translated as:
IF x is a swan then x is white. Emphasis on "if". — TheMadFool
Aside from a contradiction in your statement which I expect to carry some deep meaning I'll focus on the words "impossible to falsify". Such statements would be metaphysical for Popper, right? — TheMadFool
However, if that addressed is falsifiable and if we are unable to falsify it despite our best attempts, then it gives all indications of in fact conforming to that which is ontic (else, of accurately corresponding to that which is real), i.e. of being true. — javra
The above argument looks ok but actually has a flaw in that when predictions fail to materialize (aren't observed) it doesn't always mean the theory in question is false. Take for example the classic case: All swans are white. If you fail to observe white swans it doesn't mean that the claim is false. It just means that you haven't discovered evidence for the claim. The only way we can say that the claim, all swans are white, is false is by observing a non-white swan. — TheMadFool
Why is falsification more important than verification to Popper? I think the reason has to do with induction failing to provide definitive truth. If we are to put our trust in a theory it can't be based on it being true because the nature of induction only allows for tentative truth. — TheMadFool
First, Hume is difficult to interpret which makes him difficult to categorize. — Ron Cram
This is due in part to Hume's self-contradictory statements, called antinomies, in the philosophy literature. — Ron Cram
Unless one equates hate to a mere dislike of something, but this denotation doesn't seem right to me. — javra
Ditto as well as with like versus love. — Gnostic Christian Bishop
The link I put up shows otherwise. Dualism exists in our emotions, like it or not. — Gnostic Christian Bishop
The bundle theory of substance thus rejects the substance theories of Aristotle, Descartes, and more recently, J. P. Moreland, Jia Hou, Joseph Bridgman, Quentin Smith, and others." — javra
This is not Hume's theory of substance. Notice that Hume's name does NOT appear in that list. — Ron Cram
You asked for a quote directly from the Treatise. Here's a quote from 1.1.6: — Ron Cram
I don't think Hume ever claimed that individuals were immutable. — Ron Cram
I don't have a quote at my fingertips but the Wikipedia article on Bundle Theory, the one you linked above, has this quote:
"Thus, the theory asserts that the apple is no more than the collection of its properties. In particular, there is no substance in which the properties are inherent."
Wikipedia has it correctly. — Ron Cram
god said he was a jealous god when speaking of his love for us. — Gnostic Christian Bishop
Which are determined by what one loves, which is why I did not like you trying to separate the Yin and Yang of love and hate. — Gnostic Christian Bishop
I think there's a misunderstanding at the back of this, though, arising from the anthropomorphism of 'God as super-engineer'. In that vein, both the pro- and anti- sides of the argument have it wrong - if you believe that the order of nature 'proves' that God exists, then you're tending towards Biblical literalism, i.e. interpreting myth as fact; and if you believe it 'proves' that God doesn't exist, then you're tending towards scientific materialism, which is kind of a mirror image. (That's why, as many have noted, Dawkins himself comes across as a kind of secular fundamentalist.) — Wayfarer
In any case, interesting to note that many modern classical (e.g. Thomist) theologians and philosophers will have no truck with any design arguments whatever. For that, they are sometimes branded as atheists or closet atheists by the ID advocates - which says a lot, in my view. — Wayfarer
I'm primarily asking because in a forced choice between actualizing Nirvana and actualizing an absence of all suffering via the noneixstence of all future life, I so far view the first to be less fantastical. — javra
I am not sure what you mean by being less fantastical, but the idea of Nirvana is not deviating from Schopenhauer. In fact, it aligns well with him since he very much agreed with Hindu ideas of Moksha and Buddhist Nirvana as salvations of sorts for the Will to diminish its constant state of desire. So quite the opposite actually. — schopenhauer1
[...] I provided Hume's quote saying that he understands that his theory of personal identity is not correct and that he cannot find a way to rescue it. — Ron Cram
Hume's bundle theory states that an objects consists of its properties and nothing more. — Ron Cram
No, all material objects are mutable. The substance objects are made of are well characterized. Take any object to a condensed matter physicist and they can tell you all about the substance and its properties. — Ron Cram
