There is more than one sense in which we say someone is following a rule. If I if I ask a child what the rule of counting is more than likely she cannot state a rule but will simply demonstrate how it is done by counting. — Fooloso4
I believe counting is intuitive — Janus
How do you tell that a child has followed the rule of addition? By looking at a finite set of examples. But, as for all induction, no finite set of observations can imply a universal principle. — Banno
Except that the topic is following rules. — Banno
There is no fact that ensures the extension of a concept into the future or a new context. — Antony Nickles
When you communicated in the past, you weren't following any particular rule. Meaning does not arise from community rule following. — frank
Admittedly, we have met the sceptical challenge by relying on an as yet undiscussed notion of intention. It should be recalled, however, that Kripke himself introduced this notion as being relevant to the sceptical problem, thereby suggesting that the notion is at least intelligible. Intention, indeed, makes all the difference. For assuming that an intention to use the standard interpretation of addition is present in S's mental history, we can readily admit that no object in the world, no picture in the mind's eye, no formula of any sort determines by itself how S goes on to employ the rules of addition. And we can do this without entertaining any sceptical doubts about his ability to add. Thus, should the sceptic challenge that '(x)', for instance, might mean '(x<h)', S can readily reply, 'But that's not how I intended it'.
This, however is not how Kripke conceives of intention. As a matter of fact, he excludes from the scope of his paradox the things to which Wittgenstein applies the paradox of §201 and he includes the things Wittgenstein would exclude... — Paul Moser and Kevin Flannery, Kripke and Wittgenstein: Intention without Paradox
The article is paywalled on the links I found, so I guess we will have to take your word for it. — Banno
Yep, the generally agreed view is that the problem Kripke posits is not found in Wittgenstein, that Kripke should not be seen as engaged in exegesis. — Banno

A natural reply to the sceptic's challenge is that S intended to use 'plus' in accordance with certain laws not satisfied by the quus function, i.e., the recursion equations for '+': (x) (x + 0 = x) and (x) ( y) (x + y' = (x + y)'), where the apostrophe indicates successor. This intention of S's, we might propose, constitutes the fact that S meant plus, and not quus, for only addition conforms to these laws. But Kripke opposes this kind of reply on the ground that 'the other signs used in these laws (the universal quantifiers, the equality sign) have been applied in only a finite number of instances, and they can be given non-standard interpretations that will fit non-standard interpretations of "+" ' (p. 17).
Kripke's objection, however, misses its target. For while it is true that S might have given '(x)' or '=' a non-standard interpretation, it is also true that S might give these signs a standard interpretation. Suppose then that S understands the universal quantifier in accordance with the standard interpretation, while intending to use 'plus' in accordance with the above recursion equations. In this case Kripke's objection will not apply. [...]
But, of course, we cannot therefore infer that S can answer the sceptic's challenge to the sceptic's satisfaction. For clearly S's having a certain intention that constitutes his meaning plus does not entail S's being able to establish beyond any doubt that he has (or had) such an intention. [...] Of course, the sceptic might object to S's reliance on non-demonstrative evidence or on memory beliefs in particular. But this kind of objection will give rise to a sterile form of scepticism, as one of the ground rules for any useful exchange between the sceptic and the non-sceptic is that justifying empirical evidence need not be demonstrative evidence. Insisting on such evidence, if only for the sake of argument, S might challenge the sceptic by asking what he means, or intends, by 'quus'. Further, the present sort of objection certainly will not provide us with a new form of philosophical scepticism; at most it will provide a traditional kind of epistemological scepticism to which recent philosophical literature provides some plausible replies. — Paul Moser and Kevin Flannery, Kripke and Wittgenstein: Intention without Paradox, pp. 311-12
...not because anyone involved is consciously following rules, but because it's following a well worn pattern, — frank

Hmm. What is a pattern, if not some sort of rule-following? OR perhaps, there are two ways of showing that you understand a pattern - by setting it out explicitly in words, and by continuing it.
So here's the problem. Consider "101010..."
Someone says "you are writing a one followed by a zero, and you intend us to understand this as continuing in perpetuity"
Someone else says "The complete pattern is "101010010101", a symmetrical placement of one's and zero's".
A third person says "The series continues as "101010202020303030..." and so on, up to "...909090" and then finishes".
Our evidence, "101010...", is compatible with all of these, and much more besides.
It's not the absence of rules that is puzzling, it's their abundance. — Banno
Yes, explicit rules are in a way post hoc. — Banno
