Well, for me the
intention matters; is the intention communication (and yes, art
is communication as well - it communicates the artists feelings at the time)?
If the intention is to communicate how many moons have passed, why is tally marks not considered written language?
We talk about the language of mathematics, and no one bats an eye, but tally marks still fall into the category of language of mathematics.
I am seeing the stated criteria as a distinction without a difference: The intentional mark `5` signifying how many moons have passed is somehow different to the intentional mark `|||||`, but no one is explaining what the difference is.
