I'm asking what kind of thing a set of rules is, fundamentally. What kind of thing is a set, fundamentally? — S
"Set" is a name used to pick out a group of different particular things. All these particulars have something in common. The commonality is what makes them part of the set.
A set of rules is a group of rules. A more interesting and probing question remains...
Are the things in the set existentially dependent upon our taking account of them?
What kind of a thing is a rule, fundamentally?
That's debatable... obviously.
Is the rule existentially dependent upon being taken account of?
Perhaps a better question is this...
Does everything that governs the behaviour of thing count as being a rule, even when and if we have not yet taken it into account?
Gravity(space-time) governs behaviour. The Second Law of Thermodynamics governs behaviour. Shrodinger's Equation describes/predicts it. F=ma describes/predicts it. Does that difference between governing and describing matter here?
I would think it mattered to what counts as a rule, if all rules govern.
Another thing...
Some rules can be broken. Others cannot. Both govern behaviour. Not sure if talking about rules lends itself to substantive philosophical thought about the ontology of linguistic meaning.
What kind of thing is language?
Shared meaning being used to influence the world and/or ourselves. The use is important here, as a result of the fact that two creatures can share meaning and no know that one another exist. Shared meaning... alone... is necessary but insufficient for language. All language is existentially dependent upon shared meaning, but not the other way around.
What kind of thing is meaning?
Meaning is existentially dependent upon a creature capable of drawing correlations between different things. The drawing of the correlation is the attribution of meaning. Convention has it that there are two basic kinds of theories of meaning. Both presuppose symbolism. So... all meaning is existentially dependent upon something to become sign/symbol, something to become significant/symbolized, and a creature capable of making a connection between the two... drawing a correlation.
There are no examples to the contrary.
Linguistic meaning has this same 'core', so to speak.
What do they consist of, on a fundamental level? Physical? Mental? Abstract? Concrete? Objective? Subjective? Location? No location? Is location a category error? How does interaction work?...
I find that none of those notions can take proper account of meaning.
