Let's take a second, maybe two, and make it so that at least one of us has thought about what you've written.
Language and by extention punctuation are two non-existent constructs
This is blatantly false:
Language exists. Punctuation exists.
that are not only constantly changing but also entirely dependant upon common-usage, something that is almost impossible to measure.
I -I'm sorry, did you forget your thesis? I thought that language didn't exist?
So then I reply:
This is not so. Language is a very real construct- a formalized catalog of symbols. Punctuation is merely an agreed upon method of how to put ideas (symbols) together. While it is true that this convention is almost completely reliant on common usage, we cannot abandon rules entirely in favor of "common usage" (read: ebonics) because the accepted rules are what maintain the library of symbols' meanings.Grammar (and punctuation!) unifies the users of a language and prevents it from splintering into a thousand (or bajillion, as the case may be) regional dialects.
So therefore any attempt to disregard their usage is the very definition of Fail.
For the Cliffs Notes users among you I've bolded the relevant comment.
For my wonderfully insightful extension of the conversation I am rewarded with this gem:
It very much is so.
The parallel structure implies that you are merely asserting the opposite of my thesis. It's great that we know our respective positions. Can you back yours up though?
Language is only so real as the greatest works of fiction
Here you continue to demonstrate a critical failure in abstract thought. Just because an idea is intangible does not mean it is non-existent. For instance: the English language exists.
it exists only in your head and the signifiers you place around it. So while you may see a fish in your head and think 'this is a fish' that doesn't actually make it a fish at all. There is no innate meaning in a fish that means that it is it is termed as a fish. There is no real link between the word Fish and the body of matter that is termed a fish.
And now you regail us your confusion between the subjective nature of language and the existence of a language at all. To cut to the chase: I don't care that my symbol for "FISH" has no direct relation to the amalgamation of carbon that is collinear with what I call an "arm." It is great that you've grasped this distinction (really. I'm not even being sarcastic here.) but the point you've made is absolutely irrelevant to the discussion. We are not dealing with the material the symbols represent, but how the symbols are arranged. Thus, if I were to invent a new system (for instance: ;alkjsdkljasfiopuewqti is the root word meaning "matter" and all words consist of prefixes or suffixes to that root describing it (I am positing the unity of energy and matter) my argument would still be valid) I would still have to follow the conventions of the system I invented in order to maintain any coherence.
Language is an abstract concept that creates meaning- a system that people have created out of thin air to make the world nice and orderly. Lying to themselves that the world makes sense when in actual fact it does no such thing.
I've never claimed that the world makes sense. Not to me, at least- I have a family history of being able to sense only a thin band of the electromagnetic spectrum, in addition to reflexes honed for relatively small objects traveling very slowly in relation to the speed of light. So what do I know, amirite?
But wait! I'm not claiming knowledge of the world. 😬 I'm asserting the importance of conventions in communication. Another for instance: If you call the color of this text "blue" but I call it "green" then we will begin to have fundamental (and perhaps fatal) misunderstandings.
Punctuation and grammar is merely a way to organise a system meant to organise the world, a system that has absolutely no basis in fact whatsoever.
I like how you think that this clinches it. I don't know if I've been unclear, but your response has been a bit like a KKK member at a Greenpeace meeting:
GreenPeace: Let's go save those trees!
KKK member: And we've gotta kill the *******!
GP: go save that redwood forest!
KKK member: And lynch some darkies!
GP: wait what?
I don't care about the "basis in fact" (which is an entire topic in and of itself). I don't even care a little bit. I care about maintaining internal consistence. I would not be in the least put out if you wanted to talk about warblefs (a fictional plant from which a certain spice is extracted) so long as you carried out the conversation in correct English. (This takes as a given that you are conversing in English.)
