So we still don't have any basis for determining that S followed a particular rule. We just treat certain circumstances as if she did. — frank
Finally, the point just made in the last paragraph, that Wittgenstein's theory is one of assertability conditions, deserves emphasis. Wittgenstein's theory should not be confused with a theory that, for any m and n, the value of the function we mean by 'plus', is (by definition) the value that (nearly) all the linguistic community would give as the answer. Such a theory would be a theory of the truth conditions ofsuch assertions as "By 'plus' we mean such-andsuch a function," or "By 'plus' we mean a function, which, when applied to 68 and 57 as arguments,. yields 125 as value."
...
Wittgenstein thinks that these observations about sufficent conditions for justified assertion are enough to illuminate the role and utility in our lives of assertion about meaning and determination of new answers. What follows from these assertability conditions is not that the answer everyone gives to an addition problem is, by definition, the correct one, but rather the platitude that, if everyone agrees upon a certain answer, then no one will feel justified in calling the answer wrong.
But what would you look for in an extraterrestrial signal if you were assessing for rationality? You'd probably want to see intention, right? What tells you that an action was intentional?
Some would say we want to see some signs of judgement. For instance if we would take a sequence of constants as a sign of intelligence, that would tell us that the aliens consciously chose those numbers. Choice entails normativity. They picked this number over that one.
All of this is wrapped up in rule following, which is normativity at its most basic. To follow a rule means to choose the right action over the wrong ones.
If it turns out that there's no detectable rule following in the world, normativity starts to unravel and meaning along with it. Is that how you were assessing the stakes here? — frank
Let me, then, summarize the 'private language argument' as it is presented in this essay. (I) We all suppose that our language expresses concepts - 'pain', 'plus', 'red' - in such a way that, once I 'grasp' the concept, all future applications of it are determined (in the sense of being uniquely justified by the
concept grasped). In fact, it seems that no matter what is in my mind at a given time, I am free in the future to interpret it in different ways - for example, I could follow the sceptic and interpret 'plus' as 'quus'. In particular, this point applies if I direct my attention to a sensation and name it; nothing I have done determines future applications (in the justificatory sense above). Wittgenstein's scepticism about the determination of future usage by the past contents of my mind is analogous to Hume's scepticism about the determination of the future by the past (causally and inferentially). (2) The paradox can be resolved only by a 'sceptical solution of these doubts', in Hume's classic sense. This means that we must give up the attempt to find any fact about me in virtue of which I mean 'plus' rather than 'quus', and must then go on in a certain way. Instead we must consider how we actually use: (i) the categorical assertion that an individual is following a given rule (that he means addition by 'plus'); (ii) the conditional assertion that "if an individual follows such-and-such a rule, he must do so-and-so on a given occasion" (e.g., "if he means addition by '+', his answer to '6S+ 57' should be '125"'). That is to say, we must look at the circumstances under which these assertions are introduced into discourse, and their role and utility in our lives. (3) As long as we consider a single individual in isolation, all we can say is this: An individual often does have the experience of being confident that he has 'got' a certain rule (sometimes that he has grasped it 'in a flash'). It is an empirical fact that, after that experience, individuals often are disposed to give responses in concrete cases with complete confidence that proceeding this way is 'what was intended'. We cannot, however, get any further in explaining on this basis the use of the conditionals in (ii) above. Of course, dispositionally speaking, the subject is indeed determined to respond in a certain way, say, to a given addition problem. Such a disposition, together with the appropriate 'feeling of confidence', could be present, however, even if he were not really following a rule at all, or even if he
were doing the 'wrong' thing. The justificatory element of our use of conditionals such as (ii) is unexplained. (4) If we take into account the fact that the individual is in a community, the picture changes and the role of (i) and (ii) above becomes apparent. When the community accepts a particular conditional (ii), it accepts its contraposed form: the failure of an individual to come up with the particular responses the community regards as right leads the community to suppose that he is not following the rule. On the other hand, if an individual passes enough tests, the community (endorsing assertions of the form (i)) accepts him as a rule follower, thus enabling him to engage in certain types of interactions with them that depend on their reliance on his responses. Note that this solution explains how the assertions in (i) and (ii) are introduced into language; it does not give conditions for these statements to be true. (5) The success of the practices in (J) depends on the brute empirical fact that we agree with each other in our responses. Given the sceptical argument in (I), this success cannot be explained by 'the fact that we all grasp the same concepts'. (6) Just as Hume thought he had demonstrated that the causal relation between two events is unintelligible unless they are subsumed under a regularity, so Wittgenstein thought that the considerations in (2) and (3) above showed that all talk of an individual following rules has reference to him as a member of a community, as in (J). In particular, for the conditionals of type (ii) to make sense, the community must be able to judge whether an individual is
indeed following a given rule in particular applications, i.e. whether his responses agree with their own. In the case of avowals of sensations, the way the community makes this judgement is by observing the individual's behavior and surrounding circumstances.
I don't believe arithmetic to be merely rule following, but I think it is something we get intuitively on account of its being naturally implicit in cognition. Some animals can do rudimentary counting, which means they must be aware of number.
So, it begins with recognition of difference and similarity, then gestalted objects, then counting of objects, and this basis is elaborated in the functions of addition, subtraction, multiplication and division. Mathematical symbols and the formulation of arithmetical rules then open up the possibility of endless elaboration and complexification. — Janus
Counting makes sense as a genesis of arithmetic. But is doesn't escape from the sceptical question. There is no fact of the matter that determines whether I have counted correctly - except the fact that others will agree with me. This reinforces me in my practice of counting, as my agreement with others about their counts reinforces their practice of counting. — Ludwig V
I hope that makes it clear how I see it. I'm happy for others to disagree, provided they disagree with things I actually think, and not some imagined position based on their misunderstanding. — Janus
The challenge is about rule following, specifically about rule following activity that's now in the past. It's not an epistemic problem. It's not about what a person knows about which rule they followed. It's that there's no fact (a situation existing in the world) even in terms of mental states that satisfies Kripke's criteria for a rule-following-fact.
The idea of quadition was just to convey the problem. Kripke wasn't trying to do philosophy of math, although there have apparently been philosophers of math who were interested in it. — frank
My thoughts on it (so far) is that it fits pretty well with my belief that we aren't as rational in practice as we tend to think we are. I think some people would assume that means I end up a behaviorist, but I'd say they're making the same mistake again. They think their post hoc rationalizations are the way the world really is. It's not. — frank
Why a simple and seemingly private individualist mental life in the form of altered state of consciousness... has been represented and actualized in society to be aligned or opposed to a proper ethical way of life? — kudos

My point in indicating that everyone in the tread accepts it is to say that this burden is on you. To everyone in the thread it is accepted that we know our own actions in a more immediate way than we know others' actions, and if you disagree then you will have to provide an argument. The commonsensical idea is that when I see someone else flip a coin my knowledge is mediated by sense data; but when I flip a coin my knowledge that I am acting is in no way limited to sense data. Because I am the one effecting the act, therefore I know that the act is being effected. The mediation of the former is not present in the latter. — Leontiskos
You could come up with a million absurd and arbitrary rules like quusing, and all I can say is "so what?". The logic of counting is inherent in cognition; even animals can do basic counting. And I see no reason not to think that basic arithmetic finds its genesis in counting. Give me a good reason not to think that and I will reconsider. — Janus
If you have four piles of four objects then you have sixteen objects, three piles of three objects then you have nine, two piles of two objects you have four. This obviously cannot work with two objects, so I'm not seeing the relevance to deciding whether addition, subtraction, multiplication and division are basically derivable from counting operations. — Janus
Of course I agree that arithmetic is more complicated than counting, all I've been saying is that it is basically counting. It is the symbolic language of mathematics that allows for the elaborations (complications) of basic principles. — Janus
And I would also argue that it all finds its basis, its genesis, in dealing with actual objects, Thinking in terms of fractions, for example, probably started with materials that could be divided.
There can be no doubt that all our cognition begins with experience...But even though all our cognitions starts with experience, that does not mean that all of it arises from experience — Kant

Latching relays require only a single pulse of control power to operate the switch persistently. Another pulse applied to a second set of control terminals, or a pulse with opposite polarity, resets the switch, while repeated pulses of the same kind have no effects. Magnetic latching relays are useful in applications when interrupted power should not affect the circuits that the relay is controlling. — wiki
The SR f!ip-flop circuit is symmetrical, so it is somewhat arbitrary which output is chosen to be Q and ~Q. However, the Set pin is defined as the input that can cause Q to produce a 1 (5V) output. So one could swap Q and ~Q, but to be consistent with the conventions for SR flip-flops one would also need to swap which input is labeled S and which R. So like the stoplight it is a matter of convention. — wonderer1
Also, flip-flops themselves don't perform logical operations. They just serve as memories that can be used to provide inputs to logic gates (or combinations thereof), and store outputs from logic gates.
If you wanted to count a hundred objects you could put them in a pile, and move them one by one to another pile, making a mark for each move. Then if you wanted to add another pile of, say, thirty-seven objects you just move those onto the pile of one hundred objects, again marking each move. And then simply count all the objects or marks. — Janus
At this point it is pragmatic to jump up a level in abstraction and think in terms of logic gates instead of transistor circuits. — wonderer1
Addition, subtraction, multiplication and division are all, as far as i can see, basically counting, and counting is basically naming different quantities. Think about the abacus. — Janus
I have not understood how essences as definitions differs in salient ways from essences in terms of necessary properties. Isn't a definition a set of necessary and sufficient properties? — Banno
One way to cash this out is to say that risibility or the ability to learn grammar supervene on rationality, and it is rationality that belongs to the essence because it is explanatorily fundamental. Thus a human being is not defined as "A risible animal" or "An animal capable of learning grammar," but rather, "A rational animal." This contains and explains the others.
Aquinas claims that, in a similar way, delight supervenes on happiness, for happiness is essentially the possession of a fitting good and not the possession of delight, and yet delight always follows upon and attends happiness such that they appear indistinguishable.
I should point out yet again that it is one thing to disagree with some real definition and another to disagree with essentialism itself. The latter is much more contentious and difficult, and would seem to involve the claim that no properties are explanatorily prior or posterior. — Leontiskos
Are you looking at the 9th canon where he constructs an ever deepening series of nested a's and b's? Page 55 in my version?

What is marriage to you? — NOS4A2

I'm a bit pressed for time today, but for Aristotle the fundamental issue is that a kangaroo has an essence whereas a hammer does not, and this is because only the first is a cohesive thing (substance) with its own proper mode of being and acting (and this also includes teleological considerations). A hammer is an aggregate of substances thrown together for a human purpose.
A simpler example would be a horse-and-rider. A horse-and-rider is not a substance, and it has no essence. Instead it is a composite of two substances (a horse and a human rider). We can talk about the essence of a horse-and-rider in an analogical way, as if it were just a single thing, but technically this is not quite right.
I am not opposed to talking about the "essence" of a hammer or the "essence" of a named individual, just so long as we do not forget that for Aristotle there are no such essences. More broadly, it makes sense for the Aristotelian to say that the human has being in a more primary sense than the hammer does; or that the name attached to a perceptual 'description' is more primary than the name attached to the conceptual 'description' (and that the latter should take its cue from the former). Such a distinction may seem quite odd to the modern mind, but it may also be at the root of some of these issues. — Leontiskos
Moliere began a discussion of essences with the example of hammers. This is a strange move from the perspective of an Aristotelian, because hammers have no real essence. A hammer is a derivative being, a human artifact. Hammers should always be studied in relation to humans, because their existence is dependent upon humans. — Leontiskos
Isn't counting adding 1 to the previous number? — RogueAI

Metaphysically speaking I am unable to reduce a marriage to anything between two people, especially when it appears there is nothing between them, connecting them, and bonding one to the other. It also appears they are not “in” anything of the sort. I would say each of them relate to one another, or at least I would recognize that one is speaking figuratively when using such language. That isn’t to say one should never use the word “marriage” or “relationship”—abstractions, generalizations, universals are necessary to speak and think about the world—it’s just that one ought not to include them in his ontology, metaphysically speaking. As such he should not apply his politics to them. — NOS4A2
They are not only nominally or proximally bonded, but have a history together. — NOS4A2
But you raise some good questions in regards to political subjects (the people, the nation, the workers, the race, society). What sort of bond or relationship can we infer between the aggregate parts of these sets? Are these bonds actual? Or are they assumed and imposed? If they are not there, is it the goal of the politician to create them? — NOS4A2
In applying this subject to objects and entities outside another’s conceptual space, one would be hard-pressed to find and/or point to anything of the kind, and it would be difficult to discern what it is in the world he is actually talking about. — NOS4A2

I found this summary fairly interesting: https://www.projectenportfolio.nl/images/1/16/Robertson-Laws_of_Form.pdf — Count Timothy von Icarus
Side note: It's interesting that Brown was working on network issues. I've seen some articles on information theoretic/categorical models of quantum mechanics that attempt to explain physics as a network. This in turn, allows us to recreate standard QM in a different language, but also explains entanglement in a more intuitive network-based model (or so the author claimed, I did not find anything intuitive about the paper lol). I do find the idea of modeling reality as networks or possibility trees interesting though. But again, it's easier to conceptualize the network as a fundamental thing, rather then that the network simply is a model of process and relation, which seems to be the true basic entity! — Count Timothy von Icarus
