J, W, M. V2rhaar (42-82). But the former is more historical than methodological in its orientation: it is in fact a valuable survey of linguistic influences on anthropology in the Unitxl States - a rich and well-peopled tapestry in Hymes’s familiar manner. Verhaar’s paper is also useful and at times illuminating - in part a gallant attempt to dish up phenomenology for English-speaking readers, andB in part a comparison with Chomsky’s concept of linguistic theory. But this is simply ‘Theory and phenomcnology’ ; how does ‘Method’ in Garvin’s sense come into it? It is no disparagement of such papers to say that there is little gain in publishing them together. Nor can one discuss linguistic method simply by presenting a specific example of linguistic research. The third longest contribution has a promising title : ‘Experimental methods in psycholinguistics’, by J. Dubois and L. Iragaray (212-45). In fact it is simply a write-up of a single experiment - an interesting and pioneering experiment, concerned with the interactions of syntax and lexical collocation, but if there are any methodological cone I usions the reader must draw them by himself. Likewise F. DaneS offers little more than a summary of Czechoslovak researches into Functional Sentence Perspective (‘One instance of Prague School methodology: functional analysis of utterance and text’, 132-4(O). He adds some brief remarks at the beginmng, saying broadly speaking that the Prague School linguists have always been sound chaps who adopted a “balanced’ approach to their subject; but nothing is said in detail a’oout the methods which are illustrated. Surely the mere illustration is not sufficient for a collection on ‘Method and theory’ in general? But perhaps because of the heterogeneity of the volume, it is only the issues of theory and method which call for extended comment. In a linguistic investiga@tion, Garvin’s own approach is to restrict his a lpyio~i. theory to the minimum: a handful of ‘relatively simple assumptions about the nature of language’ (110). From these as-

sumptions we may derive a set of ‘methodological principles’ (95) which specify the type of procedure which is appropriate to a given type of analysis: in the paper before us, for exampIe, he illustrates the detailed format of a type of test which is commonly undertaken with informants - the motives and criteria for each particular tes arising, of course, from specific material at a specific stage of investigation. Now this approach is not ‘anti-theoreticat” (see the remark cited in his first footnote [95]). Nor can it be accused of con-

eliciting forms within a paradigm, of assessing the adequacy of a corpus, and the iike. It may also help if we learn to keep o”tr notebooks tidily, to recall and cross-reference our material, and so on; a good deal of Longacre’s arguably mistitled Grammar discovery ~6rocedwesis concerned with just such matters. I3ut should we admit any vital role for organised ‘linguistic analysis’? Many linguists would follow Chomsky and say no. The crucial point is that given “observational adequacy’, with respect to sufficient ‘primary linadequacy’ can allegedly be guistic data’, relative ‘descriptive measured, within an ‘explanatorily adequate’ theory, by means of a. formal evaluation. Qua theoreticians and methodologists we are not then ‘interested’, for example, in th; structure of a ‘behavioural test’ . $B?f,\, ,* taking for morph-segmentation (Garvm’s **PO+ rhlJL ;l~ll+=atio~, lll\lO1. .‘-m____ tfrp ___-1 grammar as a whole, ‘rules’ which assign a set of ‘structural descriptions’ with the right segmentation should be ‘simpler’ (SC. in terms of an er,+&icaily correct evaluation measure) than those which get it wrong. NOWLongacre does not speak in such language, at least. Rut we might put it to him: in principle, is there anything in this aspect of Chomsky’s philosophy which he would not be willing or else driven (by the logic of his remarks before us) to accept? By 1964 American attitudes on this point had already so far hardened that the conference yielded not a breath of a discussion. The stock argument for an evaluation procedure is that it is, in fact, the w ?akest requirement that can be placed on a linguistic theory: one recalls the relevant chapter in Chomsky’s SJV&JG~Z'G strzcctures. Garvin’s 0 wn proposals can only be interpreted, through these eyes, as an attempt to meet the considerably stronger requirement of a discovery procedure. But a grammar is nothing less than a theory of the particular language; surely in other sciences it is unheard of to demand, etc., etc. Unfortunately, such recitals have been dinned so persistently in our ears that we are apt to forget that they are sometimes irrelevant . Marly iinguists are not concerned with a formal procedure of any kind. Quite simply, they would dispute that either the development or the evaluation of hypotheses can be the province of a ‘linguistic theory’ in Chomsky’s sense. Thus Garvin’s concept of a general theory is, as we have seen, significantlv restricted. He RIV rejects the concept of a grammar as itxlf d ‘theory’ ; it is simply ‘a description based on a theory’ (95).

It is only in this wider context that a profitable ct One important q is whether evaluation procedures in turn are feasiblf: t us accept the case against dist a formal metatheory tthe the most adequate theory iven data. But is it not indeed extraordinary to expecl that a metatheory should provide assessments of empirical correctness (in Ghomsky’s ‘descriptive’ sense) at all! Adequacy, it would be said, can only be the fruit of a sound and imaginative application of ii uistic method : techniques of observation, analysis, ex rimc,nt, d so on, We have again no right to demand that a theory of ‘correctness’ - even of reiative ‘correctness’ - of theories sI!ould plaovide a ‘rigorous’ solution. Now the transformationalist answer 1.0 all this presumably lies in the theory of universals. An explanatorily adequate theory is, above all, a restriction of the type of gramnlar for which correctness is even admissible: this involves a specificiktion of ‘formal’ universals (as is in part attempted, whether successfuI.ly or unsuccessfully, in Longacre’s paper) and also of ‘substantive’ universals which restrict, to put it loosely, the very categories in terms of which the data may be analysed. It is not on the mere evaluation measure, therefore, tha ake burden is intended to fall. The basic error of Marvin and many others, one would reply, is to work from a general model which is s;3 arbitrarily impoverished. It is in this comlection that we may turn to P. M. Postal’s contribution : ‘The method of universal grammar’ (I 13-27). Postal’s roncerns the retlexive construction : after particular illustrattion ._-,~anrrnng the facts of English in particular and then Mohawk in particular (11644) he abstracts a pair of rules, for ‘ordinary anawhich are tentatively ‘assumed’ phora’ and ’ reflezcive anaphora’, (124) to be obligal ory for all languages. The fact that such rules can be formulated, ‘in such diverse and superficially different languages as Mohawk and English’, is ‘some evidence that a rich universal grammar does exist and is discoverable’ (127). The discussion which followed was agai,n devoted, in the main, to the specific substantive

proposals; in fact, some of Postal’s points were verye tentative. One questioner also wondere (I (whether ‘universal statements’ can be made on the evidence of just two languages (130). Postal’s reply is, of course, in principle correct : such statements are intended as hypetheses, and indeed it is ‘perfectly reasonable’ for a hypothesis to be advanced on nc: contrastive evidence whatsoever (~oc. cit. ; see also a comment by Victoria Fromkin at an earlier session [36]). On the ot.her hand, we must also abide by the standards of responsible scholarship. I might suggest, let us say, that all languages use similar particles in locative and temporal expressions (e.g., English i~zLondon or in A@& at WembZr!y or at teatime, and so on). This is verifiable anuA m;ah+ 1111~U &be interesting if true. However, it can already be checked extensively with the aid of published grammars. It would therefore be a cause for scandal -though not, we will still adrnit, for methodological scandal - if I were to publish a paper without first doing ‘so. ‘Izut surely Postal’s approach is open to more serious objections. How precisely, we must ask, does one frame and verify hypotheses of this kind? How do we determine, for example, if the reflexive constructions of Ianguagqs X, y and z do in fact display significant resemblances? Now many linguists would .begin by asking for a definition of the term ‘reflexive construction’. We may then have to inquire, as a first step, whether all our languages ‘have got’ constructions to which this term is applicable. If so, the answers will themselves be interesting. Alternatively, the definition may be such that a language could hardly be expected not to satisfy it: thus it might simply be based on co-reference within one-verb sentences Ne hit himself being ‘refle:;ive’ just because the /ze and h&self refer to the same person. In eii her case, we will then find that the construction in any particl+r !22,-~a+m display:; three sorts of properties. The first are simply the defining properties themselves. The second are those which may be shown to follow from the defining properties, either directly or in conjunction again with r;‘eatures that can hardly be expected to be absent. For example, if ‘reflexives’ are indeed established simply by co-reference it 1s inot surprising that, in addition, reflexive sentences such as We hit hiwad/ or I hit m~~~st$/ can be seen to fil; out paradigms composed of sentences without coreference, such as He hit me and I hit him (cf. Postal’s properties E3 for English, M3 for Mohawk). Thirdly, however, there will be many properties that seem entirely independent. For example, it does net

If eithe of these was universal - which, of course, t lhey are not ,- we eou claim to have made a ~+~.~ine discovery. A+n, we could pro rly advance the hypothesis {compare Postal on the basis of E and M6) that an element which marks the reflexive i t9 simple sent rices will net cr appear when the relation of co-reference extends into an emt:~&?eJ structure. This too is prilna facia wrong (e.g., Latin se in the Accuxat ive and Infinitive construction), but a’: least we know what VIe are doing. We can pro~xse genuine hyl:otheses, which can be verified or falsified for any language on which we have the information. Unfortunately, this does not appear to be Postal’s way of procerc?a ing. He does not begin with an Q:@+ori definition of ‘reflexiveness’ ; we &are merely referred to ‘c&ses of sentences . . . which have traditionally been ca.Iled’ by this name (I 16). Nor does he examine his listed properties of English arld Mohawk to see how far they may be interdependent; ht if they do not initiall>, ‘seem’ independent then the fact that cc?rtain ‘similarities’ are ‘predicted’ by his rules (126) is of scant explanatory interest ! Now tht? lack of a definition would be comprehcrm~ible in an inductive study. We would begin, let us say, by writing ;L generative grammar for English ‘in its own terms’. This might contain a ‘syntactic feature x which is realised in str& eta. $$rite separately we would then write a grammar of Mohawk, alsc ‘in its own terms’.

preach which Postal intended! To describe each language in its own terms is for him ‘as misguided as it is impossible’ (127). And, of course, we would be back with all th91:problems of inductive linguistic analysis which the transformationalists have been trying to escape from. But how does he, in fact, propose to guarantee a scientific basis? His particular ‘hypothesis’ consists, as we have said, of two rules: the first assigns a feature ‘ + Anaphoric’ to any Noun-phrase that is identical with a preceding Noun-phrase in the same deep structure, and the second an additional feature ‘-+ Reflexive’ if, at ‘some point K in transformational derivations’, there is no undcrlying ‘sentence’ of which one but not: the other is part. Both fcaturcs are assigned to the head Noun; Postal ad& a subsidiary rule by which all modifiers of ‘ + Anaphoric’ Nouns are deleted (125). The consequence:3 for surface structure then ‘depend on the rules and lexical conditions of the relevant language’. Thlls English has a special rule for se& Mohawk for ntat, and so on. Bl~i how in principle could such a ‘hypothesis’ be falsified? Obxziously, Postal would retort, if WCfind a language whose grammar could not contain them! But is such a language conceivable - one ‘Lhat can be generated, that is to say, by a transformational gramma but net, for example, if it assigns the feature ‘-+ Keflcxivc’ in this sort of way? Presumably there are two possibilities. The first is that the deep structures might not meet the conditions uuder which these rules apply. But that means, in effect, thlzt the language would exclude co-reference : that its ‘semantic representations’ could not include the equivalent of English sentences such as He kit kintsetf, John said he (i.e., John) co&d not co1;12e, and so on. This hardly seems likely. The second 3s that its ‘surface structurrts’ could not be derivccl f; om the intermediate structures, ‘at level K’, which result from their application. But how can this be imagined ? Let us suppose, for example, that ‘EC’is such that in Latin grammar a structure such as Caesar dixit $hesarem ueGsse]s will indeed exist without CQc:scgYerN,b being marked as ‘+ Reflexive’. Nevertheless would we ha.ve any difficulty in writing a transformation - SOME transformation, at least - to derive tile Pronoun se correctly ? Let us imagine, again J ;:L quasi-English in which He lzit Jzijn is ambiguous in precisely the sarm: sense as He said be cotildut’t. Would we have any difficulty in form-_+ lating ‘lexical co:rlditions’ by which the realisations of [3rd singular, + Reflexive] andI [3rd singular, - Reflexive] fell together?

Now at this point a pigeon-holcr may be tempted to redefine i;ur discipline. Experimental phonetics, he might say, is not a branch of linguistics at all. Instead it belongs to psychology - cross-classified no doubt, but nevertheless with under ‘linguistic psychology’, methods that only find their coherence in the psychological field. Contrast, comparative philology must be reassigned as a branch of history - subclassified, perhaps, under prehistory and likewise crossclassified as linguistic rather than political, economic, and so forth. Again, within the rump of linguistics proper, we could l lttcmpt a reclassification of its own remaining subdisciplines ; thul; Rona, in the paper which we have cited, proposes a scheme of ‘ cd (diachronic V~YSZLT synchronic; ‘diatopic’, for a gcographit:al study, V~YS~ZIS ‘syntopic’ ; ‘diastratic’, referring to sociocultural str Ita., versus ‘synstratic’, 200-20 1) within which sociolinguistics has its own lit tic area and methods of investigation. Now one appreciates that for many people this is intellectually attractive. And it may be that the variety of method and theory in linguistics COULD be rationalised in this sort of way. But it offers little help with the realities of out situation. A linguist syecialising in a particular language must often act both as a comparative linguist and as a phonetican, as a ‘sociolinguist’ and as a dialectologist, as a dictionary-maker and a.s a syn. chronic grammarian, simply as part of the total ;nvcs%.@ion of his data. One cannot in practice tear these various activitit?s apart : it is notoricus, for example, that a man untrained in compaiativCb linguistics may not then be able to keep his mind from the subject, but will frequently end by doing it badly. In this sense the discipline ‘linguistics’ has an ineluctable unity, and any linguist has to tnaster the large variety of ‘melhods’ that it offers. Another difficulty, let us admit, is that these methods arc often obscure. Sometimes we seem in practice to be clear enough as to what we are doing; it is surely too much to say that ‘accurate work’ is possible only when everything has been neatly codified. But occasionally we are in real confusion. At the moment, this seems particularly true of the many investigations into language universals -. which excuses, I hope, the space that I have devoted to Postal’s relatively early and exploratory paper. If people must organise conferences, then ‘The methodology of universal grammar’ is one of the less unprofitable topics that might now be chosen. In the end, however, the hard core of our difficulties springs simply
