Ruhlen's A Guide to the World's Languages is an accessible account of the honorable opposition and has a good summary of previous work in the area.
Greenberg's "mass comparison" amounts to eyeballing a bunch of lexicons and guessing that certain languages are related. This in itself is normal and necessary. It is what happens before you apply the comparative method and attempt to rigorously prove a connection.
As I like to say about mass lexical comparison, the difference between it and the comparative method is that between asking a question and finding the answer. And the question mark won't straighten by itself. Greenberg's list of lookalikes doesn't say, "These languages are related", it says, "Are these languages related?". Of course, asking the right question is the first step towards finding the answer; but in the case of Amerind, we can't be sure that it is the right question. Of course, it is at least a
legitimate question, but one may ask why Greenberg excluded Eskimo-Aleut (a well-established family) and Na-Dene (a grouping which is controversial but at least worthy of serious discussion). Probably, his reasons were that these groups largely coincide with populations that were shown to be late arrivals by means of genetics. But recent genetic studies and archaeological finds have drawn the "Clovis model", according to which all the other indigenous Americans descend from a single founder population that passed the Bering land bridge about 12,000 years ago, in question, and that undermines the Amerind hypothesis.
zompist wrote:The controversy is not about whether mass comparison is useful, or whether Amerind is possible. It comes when Greenberg and Ruhlen deny that any other evidence is needed. (See Ruhlen, op. cit., p. 253: he describes it as a "serious error" to require "the presence of regular correspondences and the reconstruction of proto-forms", that is, the comparative method.)
The sad fact is that reconstruction takes a long long time. (Look at the fact that we have an active PIE thread: there are still controversies in this most studied of language families 200 years after the family was proposed!)
Yes. There are still a lot of controversial things in the reconstruction of PIE, despite IE being the best-studied family of all, and with the luxury of having ancient literary languages at disposal that bridge about half the time since breakup. With Uralic, things look worse, for instance, and with most other families, even worse still.
zompist wrote:A lot of the families you see in overall classifications (including mine in the sci.lang FAQ) are not in fact supported by the comparative method, simply because no one's got that far yet. E.g. Greenberg's classification of African languages is generally accepted by Africanists, but has not been established by reconstruction. There are reconstructions of Bantu, but not Niger-Congo. There are reconstructions of Algonquian, but not Almosan.
Yep. Of Greenberg's four African macrofamilies, none has been reconstructed yet, though Afrasian and Niger-Congo show morphological similarities which suggest that these two at least are valid. But these resemblances aren't really closer than those between IE and Uralic! So there is a lot left to do here. It seems that Greenberg used the following algorithm:
1. If it looks as if it was related to Semitic, it goes to Afrasian.
2. If it looks as if it was related to Bantu, it goes to Niger-Congo.
3. If the above fail, and it has clicks, it goes to Khoisan.
4. If the above fail, and it doesn't have clicks, it goes to Nilo-Saharan.
So, two language family
candidates, one grouping based on a single typological feature, and one wastebasket.
The Khoisanists at least seem to have realized that they have no valid evidence of their field of study being a single family.
At least, these four macrofamilies are somewhat useful for the purpose of classification. Amerind, in contrast, isn't.
zompist wrote:As I mentioned in the other thread, something that seems obvious at first look— that is, when you apply mass comparison— may completely dissipate when you apply the comparative method. An example is "Quechumaran", a node intended to include Quechua and Aymara (and some remoter relatives of Aymara, such as Jaqaru). There is a large number of cognates... however, there is almost no variation between the Aymara and Quechua forms (there is more variation within Quechua), and the majority of words are spectacularly non-cognate. Grammatical endings don't match up at all. There's a good explanation for this: borrowing. One of the languages massively borrowed from the other, just as English did from French, Japanese did from Chinese, and Farsi did from Arabic.
(These remarks are based on my own attempt at reconstruction, and supported by e.g. Bruce Mannheim. Campbell also dismisses the surface level of cognates as borrowings, but believes he's found a deeper level that does point to a connection; but he gives no examples and I've never seen his data.)
Fine. If many open-class lexemes match but the morphology doesn't, one can be sure that one is dealing with loanwords. This was how Hübschmann established that Armenian was not an Iranian language in 1863. This is also what fuels the criticism levelled against the Altaic "family". The open-class lexemes are once again more similar than the inflectional morphology. (Though there are also similarities in the personal pronouns - which, however, also encompass IE, Uralic and a few others.)
zompist wrote:Did Greenberg have some magic that allowed him to avoid such problems? No, he did exactly what I did when collecting numbers: he wrote down vocabulary items from dictionaries into big notebooks. (I'm pretty sure his notebooks are available at his university.)
Yes.
zompist wrote:You have to be particularly careful with Amerindian languages, because the data are often in bad shape. Lexicons always look nice in print, but they were often recorded by untrained people with English- or Spanish-trained ears. As just one example, Ives Goddard gives the example of Beothuk 'gathet' and 'yazeek', both words for 'one' from different sources, which have been compared to Proto-Algonquian *nekwetw- and *pe-šekw- respectively. But Beothuk is extinct and poorly recorded, and Goddard's best guess is that the two Beothuk "words" are two attempts at the same word, possibly something like /ɣażiʔ/. Specialists in the area can work out these things, but a generalist looking at published wordlists cannot.
As another example of how bad early work could be, Campbell mentions a work by Sapir (a perfectly respectable scholar) linking Beothuk and Algonquian with 16 words. Ruhlen discusses Sapir's speculations without mentioning how little basis some of them had.
If you want to dig into the fight, there is no conspiracy— go get the data and reconstruct a family that hasn't been properly treated yet. There's a huge amount of work to do in South America. In a couple hundred years maybe your successors can work up to Amerind.
Amen!
