We walked on the moon in 1967. In 1968 MLK and RFK were assassinated, the cities burned, and in the following years the country realized the government was lying to us about the war in Vietnam. US society has never been the same. — fishfry
Yes I have. I even explained to you the mechanism by which the cause is logically prior to the effect via the act/potency distinction. — Agustino
Yes, there is a priority in terms of potency and act. The line (or point or whatever) is a potency of the pencil which actually exists. This logical asymmetry between the two is what guarantees the logical priority of one over the other. That is why the pencil can cause the line, but the line cannot cause the pencil. — Agustino
Except that he says mathematical propositions (like other formal propositions) acquire their sense from extra-systemic applications, otherwise they would be syntactically right but empty, a literally useless game of signs. — Πετροκότσυφας
Depending on what we are talking about, the cause can be "physical" and the effect "non-physical", or vice versa. Or it is even possible that they both be "physical" or both be "non-physical". quote]
Right, so why would this mean that it is not useful to distinguish between physical and non-physical?
— Harry Hindu
Again you evade the questions we need answered in order to make any sense of what you are saying. — Harry Hindu
What exactly IS the distinction being made anyway, and why? If I have said that information is both "physical" and "non-physical", then what use is there to make a distinction between them? If you're wanting to simply make a distinction between different kinds, or forms, of information, then you aren't making an argument against anything I have said, as it is all still information. — Harry Hindu
Non-physical" does not always precede the "physical". The idea of your mother does not precede her material existence. If it did, you have a great deal more explaining to do - like how it is that you are even here - an effect of physical causes like sex and birth. — Harry Hindu
Except that "two plus two equals four" is a mathematical proposition. Splitting food and assorting things is not. I was referring to the latter. Tell me MU, so that I might understand what you're saying, is "two plus two equals four" right according to you? If it is, in virtue of what is it correct? — Πετροκότσυφας
Sure. You can always prefer math that fail to build houses and fly planes as good as the ones we use. Why you would do that, I don't know, I wouldn't and people tend to want houses that do not collapse and planes that do not crush, but, sure, you can do that. In a less queer fashion, the principles are the extra-mathematical practices and the practices internal to our mathematical systems, i.e. established procedures of calculation. — Πετροκότσυφας
So, twice two four is not correct simply because "that's what everybody does". It is correct because we want ways to do stuff out in the world and we have found that this specific and syntactically rigorous system of calculation within which twice two four is decided, helps us do exactly that. Had you built an equally rigorous system which would help us do stuff out in the world and in which twice two twentyfive, would just mean that you built a new system, not that twice two four is wrong in the old system. — Πετροκότσυφας
The cause is the movement of the pencil, and the effect is the creation of the line, not its being. — Agustino
This is because its being depends on other - indeed temporarily posterior - causes relative to its creation. Of course, those causes, relative to its being, will also be simultaneous. — Agustino
They are simultaneous. The fact that I don't see the point on the paper without moving the pencil out of the way does not indicate that there is no point that has appeared there, only that I do not see the point. Those are two different things. I don't need to see the point for it to be there. — Agustino
Maybe at this point we should ask what we want the term 'real' to do for us. And I suppose also the concept 'physical'. Do either of these notions become become disturbed if I bring into the discussion the idea that memory is itself a reconstruction, that there is no such thing as veridical memory, and therefore we do t have access to a trailing order of pasts that we can line up and study?
By this way of thinking our past is actually in front of us in a way not unlike the present. Each past that we recollect is in a sense a fresh past, and points ahead of us. Recall is always for some future-oriented purpose of ours, so it is anticipatory. — Joshs
But
if memory itself isn't just a veridical
internal carrying of external objects via symbolization, but an inseparable component of a relational complex of the experience of the present, an experience that is at every moment disturbing our sense of past as well as present, then we may want to reimagine physical as more radically relational than traditionally assumed. — Joshs
So yes, the becoming of the thing is temporarily prior to its being. So what? — Agustino
Take it another way. The pencil is the cause of a point on the paper. The pencil touching the paper, and a point appearing on the paper are simultaneous, not temporarily separate. — Agustino
Some things can't come to exist without the priors. — Marchesk
This doesn't follow, because the future, when it becomes present will be physical in just the same sense as the present is and the past was. — Janus
It is better to say that the future is non-actual; it exists only as potential, and if nature is not deterministic; what it will be is not yet determined. — Janus
There doesn't need to be a temporal progression. The cause is logically, though not temporarily, prior to the effect. Why logically? Because the cause must contain the effect within it, and not the other way around. — Agustino
No, that doesn't tell me that it's not simultaneous, that just tells me that one is cause and the other is effect. — Agustino
The pencil can move without creating a line - if it doesn't move while in contact with, say, a page. A line cannot move a pencil, since it doesn't have that potency. Only a pencil has the potency of creating a line when moved on a paper. But the creation of the line and the movement of the pencil are simultaneous temporarily, though not logically, as explained above. — Agustino
Basically, the 4 causes leave no gaps. Efficient cause and effect are understood to be temporarily simultaneous, so the Humean notion that we could imagine A happening first without being followed by B is false. Since A (the cause) is simultaneous with B (the effect), they cannot but be linked. Like drawing a line on the paper. The line that is drawn (the effect) is simultaneous with the movement of the pencil (the cause). — Agustino
Husserl said that each moment of experienced time( time consciousness) was a tripartite structure of retention, Immediate presentation and protention. In order to experience any 'now' , we are also experiencing g the passing of the just prior now, in he form of retention, a kind of trace of memory. The now also has a protentional component, an anticipating or intending beyond itself into the future. If you think about it, this makes some sense. Awareness is situated as anticipatory, as being directed toward the future. — Joshs
The fact of the matter is that experienced reality never repeats itself exactly, not our perceptions moment to moment or our conceptually accessible world. So we are already used to the idea, from our own experience of it, that the future is going to evade our attempts to precisely duplicate our present or past. Rather than making future reality, however you want to characterize
it, nonexistent, it does the opposite. EX-istence moment to moment implies a certain aspect of non-predictability, of exceeding the past in some qualitative way. But that isnt normally a problem for us. For instance, our perceptual system is designed to optimize for regularities, patterns, consistencies in the flux of incoming sensation. So we don't normally notice the fact that our perceptual world is not self-identical moment to moment. It apppears that way to us because our perceptions abstract the regularities. — Joshs
That is what the physical world is, a reality of constant flux, out of which we are able to extract and construct regularities.
If we try to turn these regularities into determinisms, we may preserve a prectability at the cost of a meaningful understanding of a constantly developing world. — Joshs
Some things, like the integers, are included in that domain, and other things, like the square root of -1, are not. — Wayfarer
To clarify, I was referring to information pointing to no concepts, that is, meaningless raw data, like statics from the tv set, perceived by the senses but unintelligible to the mind. Otherwise, I agree that meaningful information must be non-physical, for the reason you pointed out. — Samuel Lacrampe
You are once again confusing the symbol or word, with the concept it points to. Yes, we can change the symbols 1, 2, 3, ..., but we cannot change the concepts I, II, III, ... As such, we can make 1+1=3 if we change the symbols, but cannot make I+I=III <-- As you can see, there is one too many bar on the right side of the equation, which makes it unbalanced.
And as it is with concepts of numbers, so it is with other concepts. E.g., we can change the word "red", but the concept of red-ness will remain unchanged. — Samuel Lacrampe
A rock participates in the form of rock-ness, even before a subject observes it or find a word or symbol for it for the first time. — Samuel Lacrampe
think this is very close to the naturalistic fallacy. And besides, none of the quoted passage does anything to address what has been rightly called The Unreasonable Effectiveness of Mathematics in the Natural Sciences. One of the noticeable achievements of mathematical physics, is to discover hitherto entirely unknown, and even unsuspected, properties of matter, on the basis of mathematical symmetries and reasoning. To reduce mathematics to 'behaviours' seems comically insufficient to account for these achievements. (It's also worth mentioning, again, the considerable influence of Platonism on the development of modern scientific method, via the influence of the Italian Renaissance humanists on Galileo, among others.) — Wayfarer
Isn't that my point - that it ISN'T useful to make such a distinction when talking about causation and information flow?
What exactly IS the distinction being made anyway, and why? If I have said that information is both "physical" and "non-physical", then what use is there to make a distinction between them? If you're wanting to simply make a distinction between different kinds, or forms, of information, then you aren't making an argument against anything I have said, as it is all still information. — Harry Hindu
Nope, it's not correct by definition, because there's nothing in place to make it right or wrong. — Πετροκότσυφας
Nope, it's not uniform practice itself that makes it right or wrong. It's not the criterion, it's the presupposition for the emergence of the criterion itself. It's the rule, which is based on uniform practice, which makes it right or wrong. — Πετροκότσυφας
Based on that, it's only natural to harden this basic mathematical practice, inherent in this situation, into a rule. Three kids = split food in three. — Πετροκότσυφας
But if the infolding of the universe is a process in which each present moment of time is not exhaustively predictable in a linearly causal fashion from the previous moment, then time becomes something more than an empty construct. Or one could say, the nature of objective reality itself presupposes novelty. — Joshs
So, I correctly guessed Manafort then Flynn. Let's see if I can make it three for three. Next is Kushner. — Michael
No, you still have it wrong: that there has been a pattern or regularity to your cat's activities is a matter of observation: that there will be such in the future would be an inference. — Janus
What have I said that entails that I must think that? I don't agree with any notion that any way we might be able to think is just "all in our heads". Nature (including us) is such that we can think dualistically (among other ways of thinking); and from that it certainly does not follow that nature is, in some purportedly absolute ontological way dualistic (or monistic). I think what follows is that nature is non-dualistic or pluralistic; it has infinite, and infinitely many, aspects. — Janus
No, this is wrong. If you see your cat coming in every morning for her food; this is something you have observed. This habit of hers is not 'directly' in-the-moment-observed, like the cat herself is, but it also not an inference; you know she regularly comes in and eats the food you provide for her. — Janus
It might imply an inherent dualism in the way we think about things; but I don't think it implies an ontological dualism. — Janus
The term "behavioral regularities" does not even refer to the process of learning and its institutions. It refers to acts of sorting and arranging and W. does not hypothethise about its origin. Regarding the rest,
at least what of it is not irrelevant, it does not sound like W. I'm not sure where you've found that. It actually sounds more like you when you were replying to Samuel about school. — Πετροκότσυφας
As explained in this article:
Thus, interestingly, there is a sense in which Wittgenstein actually agrees with the line taken by Hardy, Frege and other Platonists insisting on the objectivity of mathematics. What Wittgenstein opposes is not objectivity per se, but the ‘philosophical’ explanation of it. The alternative account he proposes is that arithmetical identities emerge as a special codification of these contingent but extremely robust, objectively verifiable behavioral regularities. (Yet, recall that although the arithmetical propositions owe their origin and relevance to the existence of such regularities, they belong to a different order.) So, what Wittgenstein rejects is a certain “metaphysics of objectivity” (Gerrard [1996, 173])
A closer look at the contingent regularity relevant in this context – behavioural agreement – is now in order. (At PI §206 and 207 Wittgenstein suggests that these regularities form the basis of language itself.) This type of agreement consists in all of us having, roughly, the same natural reactions when presented with the same ‘mathematically’ related situations (arranging, sorting, recognizing shapes, performing one-to-one correspondences, and so forth.) Its existence is supported by the already discussed facts: (i) we can be trained to have these reactions, and (ii) the world itself presents a certain stability, many regular features, including the regularity that people receiving similar training will react similarly in similar situations. (There surely is a neuro-physiological basis for this; cats, unlike dogs, cannot be trained to fetch.)
So, it is simply not the case that the truth-value of a mathematical identity is established by convention. Yet behavioural agreement does play a fundamental role in Wittgenstein’s view. This is, however, not agreement in verbal, discursive behaviour, in the “opinions” of the members of the community. It is a different, deeper form of consensus – “of action”
The specific kind of behavioural agreement (in action) is a precondition of the existence of the mathematical practice. The agreement is constitutive of the practice; it must already be in place before we can speak of ‘mathematics.' The regularities of behaviour (we subsequently ‘harden’) must already hold. So, we do not ‘go on’ in calculations (or make up rules) as we wish: it is the existent regularities of behaviour (to be ‘hardened’) that bind us.
While the behavioural agreement constitutes the background for the arithmetical practice, Wittgenstein takes great care to keep it separated from the content of this practice (Gerrard [1996, 191]). As we saw, his view is that the latter (the relations between the already ‘archived’ items) is governed by necessity, not contingency; the background, however, is entirely contingent. As Gerrard observes, this distinction corresponds, roughly, to the one drawn in LFM, p. 241: “We must distinguish between a necessity in the system and a necessity of the whole system.” (See also RFM VI-49: “The agreement of humans that is a presupposition of logic is not an agreement in opinions on questions of logic.”) It is thus conceivable that the background might cease to exist; should it vanish, should people start disagreeing on a large scale on simple calculations or manipulations, then, as discussed, this would be the end of arithmetic – not a rejection of the truth of 2+3=5, but the end of ‘right’ (and ‘wrong’) itself, the moment when such an identity turns into a mere string of symbols whose truth would not matter more than, say, the truth of ‘chess bishops move diagonally.' (Note that this rule is not grounded in a behavioural empirical regularity, but it is merely formal, and arbitrary.)
The very fact of the existence of this background is not amenable to philosophical analysis. The question ‘Why do we all act the same way when confronted with certain (mathematical) situations?’ is, for Wittgenstein, a request for an explanation, and it can only be answered by advancing a theory of empirical science (neurophysiology, perhaps, or evolutionary psychology).
Related to Platonism, ‘mentalism’ is another target of Wittgenstein, as Putnam [1996] notes. This is the idea that rules are followed (and calculations made) because there is something that ‘guides’ the mind in these activities. [...] The mind and this guide form an infallible mechanism delivering the result. This is a supermechanism, as Putnam calls it, borrowing Wittgenstein’s own way to characterize the proposal. [...] Moreover, if we try to take these super-mechanisms seriously we fall into absurdities. — Πετροκότσυφας
I have said numerous times that this distinction is unnecessary as the "physical" and "non-physical" still interact and are causally influenced by each other. — Harry Hindu
You are employing a very narrow sense of 'observe' here. Natural regularities and patterns are observable, but obviously not in the sense that you can look at one like you might look at a tree. — Janus
To address your other objection: if there is some "aspect of reality" that we cannot observe, and that cannot be explained in the language of physics, it can only be daid that it is non-physical in the trivial definitional sense that 'physical' is taken to mean 'unobservable' and/or 'not capable of explanation in terms of physics'.
Any other sense of 'non-physical' implies dualism...or what else? — Janus
We don't have to resort to imagining an ideal physics. We could instead imagine the possibilities of an embrace by physicists of arguments by scientists like Lee Smolen and Ilya Prigogone that the currently accepted physical description of reality is hampered by its reliance on a static model that sees time as a superfluous construct. — Joshs
On the other hand, if we say that some future, "ideal" physics is what is meant, then the claim is rather empty, for we have no idea of what this means. The "ideal" physics may even come to define what we think of as mental as part of the physical world. In effect, physicalism by this second account becomes the circular claim that all phenomena are explicable in terms of physics because physics properly defined is whatever explains all phenomena.
If I observe the sun to rise each morning that is an observed invariance. — Janus
Yes, but I didn't say that the thing is trivial, I said that it is referred to as non-physical in a trivial sense; which is a totally different proposition. — Janus
No, logically, the description cannot be the thing described. — Janus
But I don't see why it would need to be thought to be "non-physical" in anything other than the more or less trivial senses that it is either not an object of the senses, or is not something that could be explained by physics, since physics itself presupposes it. — Janus
As far as I can tell, the hypothesis of info being nothing but arrangements of physical parts seems adequate, when concepts are not involved. — Samuel Lacrampe
Part of reality, independent of a subject. As such, math concepts are discovered and unchangeable. We cannot simply decide that "1+1=3", even if everybody agreed to do so. — Samuel Lacrampe
But my view is, I hope, a bit more radical than that - information of any and all kinds, really isn't physical at all, but is only represented physically. — Wayfarer
Digging in the weeds — fdrake
But we also need a definition of 'better'. The one I would instinctively reach for is 'more useful'. One intuition is 'better' than another under my interpretation if it enables more accurate predictions. — andrewk
Based on past posts, I have the feeling that you would reject using 'usefulness' as a benchmark for quality of an intuition. But that then begs the question of what definition of 'better' you would like to use in its place. Again I might guess that you would prefer a definition that had something to do with 'truth'. Personally, I would reject such a definition, as I do not believe in Absolute Truth.
Now my understanding is that Aristoteleans form a proper subset of those who believe in Absolute Truth. So there should be no difficulty finding a non-Aristotelean that believes in Absolute Truth, who thus could continue down that line of discussion, by accepting 'truth' as a measure of the quality of an understanding. But I am not such a person. — andrewk
I suppose that's a 'No' then. One can judge that something is a proof without understanding it. — andrewk
Perhaps a helpful parallel is a chess game. One can look at the moves in a Fischer vs Spassky game and verify that Fischer did indeed do a sequence of legal moves that resulted in Spassky being in an unwinnable position. But that is not the same as understanding the strategy by which Fischer achieved that. — andrewk
OK, when you say something is immaterial, or non-physical, what exactly do you mean? merely that it is not an object of the senses, or something else? — Janus
What we refer to as "physical laws" are observed invariances of physical processes. Things seem to reliably behave in certain ways, and we call these ways 'laws of nature'. — Janus
So, if the 'laws' are observed invariances of action of physical objects and processes, and those invariances are caused by, or reflect, the will of God or the will and/or the nature of the objects and processes themselves what else is required? Why do we need "immaterial forms"? — Janus
How do you know that? Is it nothing more than a matter of definition? — Janus
But in the world objects engender other objects in various ways, and the forms those engendered objects take seem to be determined by invariances that we call "physical laws". — Janus
Even if the forms of entities were exhaustively determined by God's will as in Leibniz's Monadic metaphysics; why would there need to be a determining immaterial form in between God's act of will and the actual, physical forms of the entities? — Janus
Meaning - the physical encoding of how to interpret the representation. — tom
Hmmm... do you think the legal system is capable to deal with those who have real power? I don't really think so. — Agustino
Once you understand the form - plane figure bounded by three intersecting straight lines - then you don’t need to imagine it. — Wayfarer
It just defies common sense that the blind understand colours, any more than the permanently deaf will fathom music. — Wayfarer
Although it would be pointless to argue that, because it’s plainly false. — Wayfarer
If his writings on metaphysics bring joy to some people, and they do not induce them to harm others, then that is a good thing (IMHO). — andrewk
