  • Diego Marconi Competence and Proper Names This paper is concerned with the semantics of proper names from two different points of view. As everyboy knows, there is a standard account of the semantics of proper names - it is Kripke's account, essentially. And there is a certain amount of neuropsychological research on proper names, or on the mental representation, or processing of proper names -not too small an amount, at this point. There is a certain amount of evidence, and there are a few theories, none of them regarded as definitive, if I read the state of the art correctly. It may be thought that such neuropsychological work is simply irrelevant to the concerns of semantics, and vice-versa. For semantics is concerned with the truth conditions of sentences per se, and neuropsychology has nothing to say about that; neuropsychology, on the other hand, is concerned with several mental performances involving proper names -retrieving them from memory, or using them as cues to a person's face- and with their place within semantic memory (in case they have a special place), and semantics has nothing to say about that. The truth conditions that semantics is after are defined on the ground of a metaphysical notion of truth, whereas the only notion of truth that can be relevant to psychology is an epistemological notion: i.e. psychology may be interested in, and may have something to say about the procedures by which we come to regard a sentence as true, not about the conditions on which it is "objectively" true.

    I tend to think otherwise. For it seems to me that any semantic theory must be such that an account of language use can be based on it. And language use, and what underlies such use, is what the neuropsychology of language is about. So, for example, if it turned out that our use of proper names is essentially based on information that is regarded by standard semantic theory as utterly irrelevant to the semantic value of a proper name, that would raise a problem. I am neither saying nor implying that that would constitute a refutation of semantic theory - God forbid. I am rather suggesting that that would open a gap between the theory of truth conditions and the theory of use. Some people -semantic dualists- believe that there is indeed such a gap, and they rationalize it by having the semantic value of some, or perhaps all linguistic expressions split into two parts or "factors": a factor that determines truth conditions and a factor that is relevant to use. I don't know if this is the right way of taking care of the gap: it looks more like an expression of resignation in the face of a problem than like a solution to it. But anyway: let us first see if there is a problem at all. ILet me start by reminding you of the main points of Kripke's account of the semantics of proper names. It has a positive side and a negative side. The positive side can be stated very briefly: proper names such as 'Plato' or 'Vercelli refer to whatever they refer to -Plato, that man, and the city of Vercelli- thanks to acts of dubbing (baptisms, or the like) that took place some time in the past, and whose efficacy got passed on to us through a kind of chain of speakers1, each of which meant to use the word to refer to whatever the previous speakers were referring to. Some details may change in the process -the phonetic form of the name, for example: the Greeks did not say 'Plato'- and occasionally something may go wrong so that the original reference is lost or replaced, but, by and large, this is how such things go. The doctrine's negative side is equally important. It is not the case, according to Kripke, that a proper name's reference is mediated by something that we might want to call a sense - a meaning. For example, 'Plato' does not refer to Plato, that man, because 'Plato' means 'the author of Cratylus ', say, and that man did in fact write the dialogue

    1In Kripke's view, a proper name's reference -in any possibile world- is determined by "a causal chain of communication" belonging to the actual world (1980, p.59, fn.22).

    Cratylus. Nor should we say that 'Plato' refers to Plato because we associate with the word -the name- a certain set of properties, or a description, or a picture (suppose it is not Plato but one of us who are alive today, say Bill Clinton) and the person in question has exactly those properties, or fits the description, or resembles the picture. Nothing of that kind is the case. There is no intermediary, unless you want to call a baptism an intermediary. Anyway, there is no conceptual, not to say mental, intermediary between the name and the object it refers to. Now, let me point out Kripke's point is not that no information is ever attached to a proper name, i.e. that people who use a proper name such as 'Aristotle' or 'Cicero' are somehow bound not to think of anything in connection with the name. Indeed, he appears to take the opposite for granted: most people, he says, when they think of Cicero think of a famous Roman orator2; people who use the name 'Feynman' usually know that he is a physicist; and so forth. If 'X' is a proper name (or, for that matter, a designating expression of any kind), people in whose linguistic practice 'X' has any room at all usually have beliefs of the form 'fX'3: they believe, for instance, that Cicero was a Roman orator, or that Feynman is a physicist. And surely Kripke has no objection against such beliefs, or some of them, being "triggered" whenever the name 'X' is actively used, or is part of a sentence the speaker understands. The point is, rather, that no matter how universal and regular such associations might be -i.e., even if there were a definite set of beliefs which are somehow 'activated' or 'triggered' in all cases in which a speaker (any speaker) uses or understands a sentence in which 'X' occurs- even in such highly unrealistic circumstances such beliefs would not constitute the meaning of 'X', nor would they be what determines the reference of 'X'. According to Kripke, nothing but the name's reference affects the truth conditions of sentences in which the name occurs. A sentence such as 'Aristotle was fond of dogs' (Kripke's example) is true if, and only if that individual, Aristotle, was fond of dogs. Similarly, the sentence is true at some other possible world if and only if that same individual, Aristotle, was fond of dogs in that possible world, i.e. iff that individual is in the extension of 'fond of dogs' as determined for that possible world. As Kripke says, his is

    a doctrine about the truth conditions, with respect to counterfactual situations, of (the propositions expressed by) all sentences, including simple sentences (1980, p.12).

    Now, of course, the theory -or part of the theory- is not only relevant to counterfactual situations: the theory is about the truth-conditions of proper-name-involving sentences in the actual world, as well. 'Aristotle was fond of dogs' is true (in the actual world, i.e. simply true) iff that man, Aristotle, was fond of dogs. If we call 'the semantic value of a word' whatever affects the truth conditions of the sentences in which the word occurs, then the semantic value of 'Aristotle' is the referent of 'Aristotle' as determined by the relevant causal chain. Such a referent may or may not as a matter of fact coincide with the object picked out by one or another definite description (such as 'Alexander's teacher' or 'the author of Metaphysics'), which, in turn, may or may not be associated with the name 'Aristotle' in a particular speaker's beliefs: nothing of this really matters for the name's semantic value, although it may matter in other respects. Notice, however, that Kripke's account is not just a theory of the semantic value of names as opposed to a theory of competence about proper names; i.e. it is not a theory of what determines the truth conditions of sentences involving proper names as opposed to a theory of what is required in order to understand such sentences.

    2"Most people, when they think of Cicero, just think of a famous Roman orator, without any pretension to think either that there was only one famous Roman orator or that one must know something else about Cicero to a have a referent for the name" (p.292). 3"To every name or designating expression 'X', there corresponds a cluster of properties, namely the family of properties f such that A believes 'fX'. This thesis is true, because it can just be a definition" (p.280).

    A proper understanding of this statement ['Aristotle was fond of dogs'] involves an understanding both of the (extensionally correct) conditions under which it is in fact true, and of the conditions under which a counterfactual course of history...would be correctly (partially) described by [it] (1980, p.6).

    Literally, Kripke does not say that understanding the statement amounts to knowing the relevant truth conditions; only that it involves such knowledge. However, I won't make much of this. I take it that for Kripke, understanding the sentence requires that one knows that the sentence is true iff the referent of the name 'Aristotle' was fond of dogs, and does not require that one has any particular beliefs about Aristotle (that he was a philosopher, Plato's student, a Greek, or whatever). There is, then, a problem for the theory considered as a theory of competence and understanding. The problem is best illustrated by reflecting on certain common cases of lexical anaphora. Consider the following short text: (1)

    Napoleon was impatiently waiting for his marshals. The emperor was furious: his orders had been disobeyed.

    There is an obvious sense in which understanding this text requires that one knows that 'Napoleon' and 'the emperor' are coreferential, i.e. that Napoleon was the emperor. And yet, in another sense that is not required. For example, one could adequately translate the text into French4 without needing to know that Napoleon was the emperor. But let us look at the first sense. It could be suggested that, even in that sense, information that Napoleon was the emperor is not required in order to understand the text: rather, the text itself provides that information. The text is so constructed as to suggest pragmatically that 'Napoleon' and 'the emperor' are coreferential (if they were not, the text would be unnatural, inappropriate, would violate a maxim, etc.). However, this is not so: the same structure could go with lack of coreferentiality: (2)

    Ney was impatiently waiting for his aide-de-camp. The emperor was furious: his orders had been disobeyed.

    without the resulting text being at all inappropriate in any respect. If the anaphoric structure were providing the information, then (2) would be providing the false information that Ney was the emperor; but it doesn't. If you believe that, on the contrary, it does, to some extent at least -i.e. it suggests that Ney was the emperor- think of the following: (3)

    Ney had been impatiently expected by Napoleon. The emperor was furious: his orders had been disobeyed.

    If (2) suggested that Ney was the emperor then (3) would indicate the same; but it doesn't. What I would like to suggest is that it is natural to regard a speaker who did not "understand" T1 in the appropriate way -i.e. by taking 'Napoleon' and 'the emperor' to be coreferential- as incompetent, exactly as we would regard a speaker as incompetent who could not sort our the anaphoric links in (4): (4)

    The mouse was closely watching the cat. The feline was pretending the rodent wasn't there.

    4 I am not sure whether that would be true for translations into any language. There could be languages in which anaphora must be marked morphologically.

    Thus, to the extent that the standard theory is not just a theory of the semantic value of proper names but a theory of understanding as well, there is a difficulty: for there are cases where understanding a text seems to require the availability of information attached to a proper name (it seems to require that one shares certain beliefs involving the proper name). I do not doubt that such difficulties could be taken care of, in more than one way: either by distringuishing two senses of 'understanding' as I just did, or perhaps by resorting to "pragmatics". I mentioned the difficulty just to give you an example of the kind of problems I have in mind. The question I have in mind is the following: what is exactly the role of beliefs such as 'Napoleon was the emperor' in our use of the proper name 'Napoleon'? More generally, to what extent and in what way does our use of proper names involve what the psychologists call 'semantic information' , i.e. information about properties of the name's referent? This is the viewpoint from which I want to look at neuropsychological research. II First of all, can we speak of proper names as a distinct mental category, or in other words, does the notion of a proper name have any specific psychological relevance? The answer to this seems to be 'yes': for example, proper names can be both selectively lost5 (i.e. the ability to use proper names is lost, while the ability to use common nouns is preserved) and selectively preserved6 (while common nouns are lost). Let me give you some examples. K.S., a patient studied by Ellis, Young, and Critchley (1989), had normal competence as far common nouns were concerned, but she could name very few people (6, controls 16.25), and her deficit extended to famous animals, famous buildings, and brands - whatever has a proper name. M.P., a case studied by Hittmair-Delazer et al. (1994), was only slightly impaired as far as common nouns were concerned, but he could name only 2/14 famous people (controls 14/14) from pictures, and only 2/22 from verbal descriptions (only Superman and Batman). On the other hand, M.E.D., a case reported by Cipolotti, McNeil and Warrington (1993), could verbally name no objects at all (0/10), and she could name only 3 objects out of 10 in writing; but she could name (in writing) 9 countries out of 10 and 8 famous people out of 10. Similarly, R.I., a patient of Semenza and Sgaramella (1993), who could name no objects at all with or without phonemic cues, was able to name 10/10 familiar people, 18/22 famous people when cued phonemically. Thus, a pattern of double dissociation emerges: some authors draw the conclusion that "proper names access from the semantic system to the phonological lexicon ... on a channel that is separate from the channel used by common nouns"7.

    At this point, let me introduce some quasi-technical vocabulary8. I will speak of lexical (semantic) competence to mean the knowledge and abilities underlying our use of words. I will distinguish two aspects, or sides of lexical competence: inferential competence is the ability to manage a vast network of words, underlying such performances as semantic inference, paraphrase, definition, retrieval of a word from its definition, synonym-finding, and so forth. Referential competence, or the referential side of competence, is the ability to map lexical items onto the world. An ordinary speaker can tell cats from cows, can point to a numeral on paper, can describe a person as running rather than walking; she can obey orders concerning her immediate surroundings -she can follow instructions such as 'Go to the table and pick up the book on it'- and she can obey an order such as 'Draw a picture of a hammer'. All such performances are based on

    referential competence. There is good reason to believe that the two sides of lexical competence are mentally separate, though usually interacting in several ways. There is also some evidence to the effect that referential competence, in turn, has two sides: there's naming - i.e. the ability to verbally label objects or pictures of them- and there's application, the ability to apply lexical labels in the world, e.g. to find an object corresponding to a linguistic description or to a word (finding a spoon, or a hammer, or a black sheep), or to pick out the right picture -a picture of a spoon, for example. There are people who are very good at application while their naming abilities are impaired9; the converse case has also been reported, though less frequently10. These notions are relevant to the cases I presented a moment ago. For example, M.P., the patient of Hittmair-Delazer, whose naming was very poor, had excellent application abilities. He could find the picture correponding to a given PN in 15 cases out of 15, while he could name only 3 of those same 15 pictures. M.E.D., a case of selective sparing of Proper names, had virtually pefect application for both Proper names and common nouns. In other cases, one can find dissociation of inferential and referential abilities. Now, the problem arises whether it is really proper names as such that constitute a significant mental category, or whether we should speak of persons' names vs. all other words, or again, whether there are subcategories of proper names that exhibit different patterns, both with respect to common nouns and with respect to one another. We saw a case in which many categories of proper names were selectively lost (K.S. of Ellis et al.), and a case in which both people's names and geographical names were selectively preserved (M.E.D. of Cipolotti and others). I know of at least five cases in which geographical names were preserved while people's names were lost11, whereas the converse case is not known to me - but that may depend on either my ignorance or the fact that not all cases were tested on geographic names. There is a case (Warrington and Clegg 1993) in which geographic names are the only words left. This is a remarkable case, for this person, A.F., appeared to have lost all competence whatsoever: he couldn't even name a chair. But as far as names of countries were concerned, he scored between 7/10 and 10/10 in both naming and application. So, there may be something special about the proper names of countries, though we cannot really speak of a separate mental category so far (for we have no double dissociation). In the sequel, I'll pretty much stick to people's names, for they have been studied more thoroughly and the evidence is more abundant. Anyway, it appears that all proper names go together in some respects at least. III Recalling a person's name seems to be a hard task, harder than recognizing her from her face or recalling her occupation or other circumstances of her life. Rather broad investigations of normal subjects found that

    9Kay and Ellis 1987, Miceli, Giustolisi & Caramazza 1991, Hart & Gordon 1992. 10 A striking case is D.T., reported by Silveri and Colosimo (1995): "When single pictures of objects were presented he immediately named them (9/10); when he was requested to point to one of two pictures in a word-()picture matching task, he named both of them, pointing at random" (p.4). I know that other such cases have been reported, some of them also involving proper names (Kremin 1986), but I have not studied them yet. 11 McKenna & Warrington (1980), Lucchelli & De Renzi (1992), Warrington & Clegg (1993), Hittmair-Delazer et al. (1994), Semenza & Zettin (1995).

    (A) people can correctly tell whether a face is familiar or not more often than they can specify the person's occupation, and they can specify the occupation more often than they can recall the person's name12;

    (B) judgments of familiarity are faster than retrieval of a person's occupation, which is faster than retrieval of the person's name13;

    (C) it is practically never the case that one can recall a person's name but not his or her occupation. For example, Hanley and Cowell's (1988) experiments with famous faces produced the following results: on 97.4% of the trials, where subjects knew a celebrity's name they also knew his or her occupation and found the face familiar. Only on 3 occasions out of 10,000 a subject found a face unfamiliar, did not know the occupation but was able to give the name; on 20 occasions subjects found the face familiar and could give the name, but not the occupation. Notice that in all such cases the subjects correctly guessed the occupation that they claimed not to know.

    Such data have inspired a model of the process of recognition and naming of people - the so-called Bruce & Young model (1986) [fig. 1].

    [insert figure 1] The model is intended to be strictly sequential: you cannot access information relative to a person unless you found her face familiar, and you cannot access the person's name unless you have accessed "semantic" information. You simply cannot know that a person's name is 'Saul Kripke' and not know that he is some sort of professor in the United States. This is because "names are not accessed directly by recognition units, but are accessed indirectly through person information" (Young, Hay and Ellis 1985, p.519; italics added). Similar results have been obtained from investigating the reverse process, i.e. the retrieval of a person's biographical circumstances and facial appearance from his or her name. What was found in this case14 is that recall of visual information on a person's face depends on prior retrieval of the person's occupation: you can't go from the name straight to the face, so to speak, without accessing semantic information in the process. On the other hand, if you start from semantic information -from biographical information about the person, for example- you can access both visual information about the person's face and the person's name, though not necessarily both. In particular, subjects may recall a person's facial appearance from biographical information while claiming not to know the person's name at all. Now, of course, researchers have been puzzled by some of these findings: why on earth should it be impossible, for example, to recall that one has a beard without recalling that he is a musician? Or, in the case of the reverse process, why should it be impossible to remember that a certain guy is named 'Boris Becker' without recalling that he is a tennis star15? Morever, people have been uneasy about a feature of both the Bruce-Young model and the reverse model, namely, that they seem to require a separate storage for proper names - separate with respect to other information concerning a person's properties, such as his occupation, age, circumstances in which he is usually met or seen, etc..

    In order the avoid the hypothesis of a separate storage for proper names, a somewhat different model was proposed in the early '90s. The model would explain why proper names are harder to retrieve than other kind of information about people without postulating a separate "box" for proper names, sequentially successive to the semantic box. This is the Burton and Bruce model (fig.2).

    [insert fig.2]

    Here the crucial idea is that ease of retrieval is a function of connectivity. In the Burton and Bruce model, proper names are regarded as bits of semantic information about people, on a par with occupation and other life circumstances: there is no separate pool or box for proper names. What characterizes proper names is that each of them is (usually) connected with only one Personal Identity Node, whereas other kind of information is connected with many PINs (for each of us knows many politicians, surgeons, postmen etc.). All connections have the same intrinsic weight, and they are all bidirectional. As a consequence, activation will tend to circulate in the system:

    If the Prince Charles PIN becomes excited, the royal SIU (say) will also become excited. This, in turn, will activate (to a small extent) the Princess Diana PIN. Because there are two PINs with some activation which are both connected to the royal SIU, this SIU will tend to be kept at a higher activation than if a single PIN were connected to ii. (Burton & Bruce 1992, p.49).

    Therefore, semantic units that have more connections will generally be kept at a higher level of activation. If retrieval depends on level of activation, this explains why proper names are harder to retrieve than (other) pieces of semantic information16.

    The Burton and Bruce model made two predictions: first, semantic information uniquely attached to a PIN should be as hard to retrieve as a name; secondly, names and occupations that are highly distinctive should be harder to retrieve than names and occupations that are common (for the former would be less "connected" than the latter). Neither prediction was upheld by later experiments (Stanhope and Cohen 1993): it turned out that both uncommon names and uncommon occupations were easier to remember than common ones, and that uncommon occupations were easier to recall than any name, common or uncommon17. Notice, moreover, that the Burton & Bruce model is at odds with data that were already well known when the model was proposed. For according to the model, the loss of proper names should be a matter of degree: for example, we should expect to find cases in which some proper names are preserved while many are lost, whereas most common nouns are preserved, though a few -the less common- are lost. What we find instead is a number of cases in which all proper names are lost while all common nouns -including the most distinctive- are preserved (McKenna & Warrington 1980, Semenza & Zettin 1988. etc.).

    Concerning the issue of how to account for the surprising facts we just mentioned -a proper name cannot be retrieved unless semantic information about the person is retrieved, and it does not give access to a person's face without giving access to semantic information about the person- I have my own hypothesis. To begin with naming: suppose that people are not recognized by matching a face, or the visual representation of a face, onto a mental catalogue of faces; suppose instead that people are recognized because a face (or the visual representation of a face) acts as a trigger to a set of scenes, stored representations of circumstances in which that particular face was seen by the subject. Recalling a scene that concerns a particular face, thus a particular person, would involve identifying at least some aspects of the scene (where it took place, what was the role of the people involved etc.), though not necessarily being able to describe it verbally. However, in the presence of normal referential competence, such a verbal description would be straightforwardly generated, so that semantic information about the person would be elicited by the very fact that the face is recognized, unless the triggered scenes are too few or too fuzzy to be identified. The person's name, on the other hand, is not an element of the triggered scenes for -to put it briefly- nothing visual corresponds to a proper

    16 The authors implemented a neural network model of their theory, yielding the expected results. 17 Also Hittmair-Delazer et al. 1994.

    name: a baker can be imaged in the act of baking bread, but Mr.John Baker cannot be imaged in any particular way because of his being named 'John Baker'. Therefore, the person's proper name must be retrieved as an independent piece of information, associated with the triggered scenes though not as an element of any of them. Similarly for the application direction: a name triggers a set of scenes which (normally) generate verbal descriptions and (normally) include visual representations of the face: thus semantic information is made available practically in the same breath as visual information about the person's face, so that it does not happen that the latter is available without the former being available as well. This model is speculative of course, but it does make some definite predictions. For example, for each single piece of information concerning a person, there would be cases in which the face is recognized but that particular piece of information (occupation, social position, biographical details etc.) is not retrieved, whereas there would never be cases in which the subject could retrieve some semantic information about the person whose face is familiar to her without being able to recall any circumstance in which she interacted with the face. IV Be that as it may, let us go back to the initial issue. Does neuropsychology teach us anything concerning the mental representation and processing of proper names that would be relevant to semantics? Let me summarize some of the results which appear to be more robust: 1) A person's name seems to be strongly associated with a set of properties that are ascribed to the name's bearer. The name cannot operate as a trigger to a person's face without triggering a description of the person as well; and, the name cannot be accessed (from a face) without accessing a description of the person. It would be interesting to investigate whether the analogue holds for geographic names as well. 2) A person seems to be mentally identified by a set of properties more than by his or her proper name. Recognizing a person involves (or, perhaps, just is) to ascribe to him a set of properties, though not necessarily a name. Conversely, a name does not lead us to a person's physical appearance without also (and probably, first) leading us to a set of properties that are characteristic of that person. 3) In fact, the role of proper names in the mental identification of human individuals (but probably of individual animals, buildings, brands etc.) appears to be relatively minor. A person can be identified, satisfactorily to many effects, even if his or her name is not known or recalled; conversely, the name does not provide access to a person's identity unless it gives access to a semantic description. For example, a person's physical appearance cannot be recalled without recalling a non-physical description of that person, and possibly only through such a description. Now, remember, the questions we had in mind were: what is the role of beliefs such as the belief that Napoleon was the emperor in our use of the proper name 'Napoleon'? And more generally: to what extent does our use of proper names involve what the psychologists call 'semantic information' , i.e. information about properties of the name's referent? It would then seem that the answers must be, to the first question, that the particular belief that Napoleon was the emperor is perhaps not crucial to our use of the name 'Napoleon'; however, some such belief must be around if certain uses of the name are to be possible, for example, if application of the name on the basis of physical appearance is to be possible - a pretty common use of proper names. So, coming to the

  • 9

    second question, it appears that semantic information plays a major role in the use of proper names.

    Now, did anybody seriously doubt that such is the case? I.e., did anybody, including Kripke, ever doubt that in order to use the name 'Napoleon' satisfactorily, one must know quite a bit about Napoleon? Probably not, even though perhaps not many were aware of how crucial such knowledge is to many performances that do not seem to directly involve it, such as putting a name to a face. In philosophy, the idea was, and is, that the problem of what is required for the use of names (in that sense) belongs to the province of pragmatics, whereas semantics proper -the study of the truth conditions of sentences- has no business with them. Whether such a split is justified -whether, for example, we can really accept to have two different and independent notions of understanding- is the theoretically important question, which I have not addressed and did not mean to address this time.
