Is there any intrinsic meaning in anything?
I'm undecided.
I'm influenced by Charles Sanders Peirce's early (1860's) theory of signs. (Peirce was continually tinkering with his theory of signs throughout his life and produced several rather different versions at various points.)
https://plato.stanford.edu/entries/peirce-semiotics/
The earlier version is actually quite simple and common-sensical and the SEP outlines it this way:
"What we see here is Peirce's basic claim that signs consist of three inter-related parts: a sign, an object, and an interpretant. For the sake of simplicity, we can think of the sign as the signifier, for example, a written word, an utterance, smoke as a sign for fire etc. The object, on the other hand, is best thought of as whatever is signified, for example, the object to which the written or uttered word attaches, or the fire signified by the smoke. The interpretant, the most innovative and distinctive feature of Peirce's account, is best thought of as the understanding that we have of the sign/object relation. The importance of the interpretant for Peirce is that signification is not a simple dyadic relationship between sign and object: a sign signifies only in being interpreted. This makes the interpretant central to the content of the sign, in that, the meaning of a sign is manifest in the interpretation that it generates in sign users."
Which would suggest that there isn't any intrinsic between relationship between a number sign ('2' for example) and its object (the quantity two, pairs, metaphysical dyads or whatever it is). What's still needed is an interpretant that interprets the number 2 as a sign for its quantitative object. Different cultures may (and historically have) invented different number signs to represent whatever our '2' refers to. (What the objects of number signs actually are is still a metaphysical mystery.)
But it may be more complicated than that. Pierce was always chasing the complications which generated the later elaborations in this theory. The SEP again:
"Put simply, if we come to interpret a sign as standing for its object in virtue of some shared quality, then the sign is an
icon. Peirce's early examples of icons are portraits and noted similarities between the letters p and b. If on the other hand, our interpretation comes in virtue of some brute existential fact, causal connections say, then the sign is an
index. Early examples include the weathercock, and the relationship between the murderer and his victim. And finally, if we generate an interpretant in virtue of some observed general or conventional connection between sign and object, then the sign is a
symbol. Early examples include the words 'homme' and 'man' sharing a reference."
So perhaps not all number signs should receive the same analysis. The Roman numeral 'II' might arguably be an icon of its mysterious dyadic object. While the numeral '2' would seem to be more of a symbol. So perhaps one could argue that the Roman numeral 'II' has more of an intrinsic number-meaning than our more familiar '2'.
