Thanks for the (double!) post in response to what I wrote
You're right that I'm passionate about this particular topic!
I do agree with you wholeheartedly about the appropriateness of dialect-use in certain settings. The "standard" language is the medium of choice in academic circles, of course, and academic work written in a non-standard dialect will not be taken seriously (though use of such a dialect in no way takes away from the content of the work itself!). Similarly, academic-sounding speech would get laughed off the stage at a rap contest, unless specifically used for humorous effect (a la Eminem). Using the "proper" variety of a language in a particular context can be crucial for communicating most efficiently.
The major point that we disagree on seems to be the development and status of dialects.
Particularly the following quote:
I feel that there is a difference between a true dialect- Scotch- and one that emerges from people's wilful misknowledge and ignorance of a standard language. When people say, 'I ain't got nothing,' on the street or in an exam (and it happens,) they are not attempting to speak a dialect; they are speaking a version of standard English at odds with its basic grammar rules.
There is so much to disagree with in here! First of all, why is Scotch any more a true dialect, than, say ebonics, or Spanglish, or Singapore English (all 3 of which get derided). Go to New Guinea and listen to the Pidgin English spoken there, which is the national language and has newspapers written in it. 50 years ago it sounded like a joke to speakers of "standard" English. Once again, "standard" English and "established" dialects are social constructs, dictated by political power, geographical borders, and sheer number of speakers, along with their control of media outlets, publishing, and so on.
How can one possess "willful misknowledge"? If one doesn't know something, they can't willfully disobey or change it! I would reckon that you are likely far more ignorant of the language used by Eastern Canadian fishermen than they are of Standard English. They may have a passive knowledge of it, but in a sense are bilingual, while you remain monolingual. (of course I have no idea what varieties of English you may be familiar with; this is just an illustrative example)
What I'd like to stress are the following 2 points:
1. Development of one dialect into a standard variety is nothing more than an accident of "being in the right place at the right time", if you will. In other words, the "right" people happen to speak it, so it spreads.
2. People speak the variety of a language they are comfortable with and grew up speaking. So when someone says: "I ain't got nothing", whether they are familiar with Standard English or not is irrelevant. They are not "willfully" ignoring rules of Standard English grammar and creating new constructs willy-nilly; they are simply saying what they are used to saying, based on actual rules of grammar in their dialect.
A very interesting example of this is Black American English as spoken here in Philadelphia. Many "educated" people listen to this and think black people don't know how to conjugate even the simple verb "to be". This is because you hear sentences like "He be flipping over dat" and other such utterances.
Research shows that the use of "be" for the 3rd person form rather than "is" is actually highly constrained to certain contexts. Both "is" and "be" co-exist, and have different aspectual uses. In other words, our "standard" variety, having only "is", lacks this richness that the so-called "inferior" variety of English possesses.
Now, just to be clear, we may be talking around each other if the only thing you really mean is that people should use Standard English when it's appropriate to do so, and they should feel free to use their own dialect in other situations. I sense, however, that you don't have a clear sense of the difference between "breaking basic grammar rules of standard English" and "simply speaking a separate variety of the language".
The fact that you said this:
Perhaps, like in the ebonics case, if people knew both how to speak standard English and this misconstrued collection of wrong things at the wrong time, maybe I would be less harsh.
was the most disturbing thing to me!
Based on this quote alone, it sounds as though you truly believe that ebonics is somehow "wrong", and hence "inferior", and that people who ONLY speak ebonics are inferior FOR THIS REASON. I hope that you can come to see that on the contrary, ebonics is a rich variety of English spoken by millions of people (many of whom do not know Standard English very well at all) with the same expressive power as the standard language, and a huge, highly creative oral literature (rap music).
In general, new vocabulary items, grammatical structures, and usage crop up for a variety of reasons: teenage "slang" as a backlash against authority figures, borrowed words to fill gaps in scientific vocabulary, coining new words using existing grammatical structures and so on. Whether they stick around to be adopted by the standard language or remain forever within a particular variety of the language is in no way related to the content of the structures themselves. It is almost random, in fact. Sometimes when communities of speakers are isolated from each other for long enough (like blacks and whites in the United States, who are largely still living segregated lives), enough changes develop to create totally different dialects. Enough time passes, and you end up with mutually unintelligible languages, like the Germanic languages or Romance languages, or going back further, Indo-European languages.
We'll leave the discussion of historical linguistics to another thread, though
OK, I've rambled on long enough! Sorry for the long post.
