A challenge for theories of incomplete descriptions is to capture the consistency of ‘Sobel sequences’ and to account for an asymmetry in the acceptability of utterances of Sobel sequences and ‘reverse Sobel sequences’. David Lewis’s theory of incomplete descriptions answers, unlike many other theories, the challenge from Sobel sequences, but it does not answer the challenge from reverse Sobel sequences. This article presents another asymmetry in the availability of anaphoric readings of Sobel sequences and reverse Sobel (...) sequences, and proposes an explanation of the original asymmetry on its grounds. This provides an answer to the challenge for Lewis’s theory. (shrink)

Standard attempts to defend Russell's Theory of Descriptions against the problem posed by incomplete descriptions, are discussed and dismissed as inadequate. It is then suggested that one such attempt, one which exploits the notion of a contextually delimited domain of quantification, may be applicable to incomplete quantifier expressions which are typically treated as quantificational: expressions of the form AllF's, NoF's, SomeF's, Exactly eightF's, etc. In this way, one is able to retain the plausible claim that such (...) expressions ought to receive their usual quantificational analyses. The conclusion tentatively drawn is that perhaps definite descriptions arenot amenable to a (Russellian) quantificational analysis. (shrink)

The implicit content associated with incomplete definite descriptions is contributed in the form of definite descriptions of situations. A definite description of this kind is contributed by a small structure in the syntax, which is interpreted, in general terms, as ‘the situation that bears R to s’.

In this paper I offer a defence of a Russellian analysis of the referential uses of incomplete (mis)descriptions, in a contextual setting. With regard to the debate between a unificationist and an ambiguity approach to the formal treatment of definite descriptions (introduction), I will support the former against the latter. In 1. I explain what I mean by "essentially" incomplete descriptions: incomplete descriptions are context dependent descriptions. In 2. I examine one of (...) the best versions of the unificationist “explicit” approach given by Buchanan and Ostertag. I then show that this proposal seems unable to treat the normal uses of misdescriptions. I then accept the challenge of treating misdescriptions as a key to solving the problem of context dependent descriptions. In 3. I briefly discuss Michael Devitt’s and Joseph Almog’s treatments of referential descriptions, showing that they find it difficult to explain misdescriptions. In 4. I suggest an alternative approach to DD as contextuals, under a normative epistemic stance. Definite descriptions express (i) what a speaker should have in mind in using certain words in a certain context and (ii) what a normal speaker is justified in saying in a context, given a common basic knowledge of the lexicon. In 5. I define a procedure running on contextual parameters (partiality, perspective and approximation) as a means of representing the role of pragmatics as a filter for semantic interpretation. In 6. I defend my procedural approach against possible objections concerning the problem of the boundaries between semantics and pragmatics, relying on the distinction between semantics and theory of meaning.

This paper offers a unified, quantificational treatment of incomplete descriptions like ‘the table’. An incomplete quantified expression like ‘every bottle’ (as in “Every bottle is empty”) can feature in true utterances despite the fact that the world contains nonempty bottles. Positing a contextual restriction on the bottles being talked about is a straightforward solution. It is argued that the same strategy can be extended to incomplete definite descriptions across the board. ncorporating the contextual restrictions into (...) semantics involves meeting a complex array of desiderata, yet the apparently simpler pragmatic alternative faces severe problems and is therefore a nonstarter. (shrink)

The purpose of this paper is to discuss two phenomena related to the semantics of definite descriptions: that of incomplete uses of descriptions, and that of the underdetermination of referential uses of descriptions. The Russellian theorist has a way of accounting for incomplete uses of descriptions by appealing to an account of quantifier domain restriction, such as the one proposed in Stanley and Szabó (2000a). But, I argue, the Russellian is not the only one (...) in a position to appeal to such an account of incomplete uses of descriptions. Proponents of other theories, such as the Fregean, which does not treat descriptions as quantifiers, might benefit from this account of domain restriction. In the second part of the paper I discuss referential uses of incomplete definite descriptions. Relative to such uses, Wettstein (1981) and others have argued that the Russellian theory faces a problem of underdetermination of semantic content. Neale (2004) has replied to this objection showing why it does not pose a threat to the Russellian theory. Again, I argue that not only the Russellian, but also the Fregean can subscribe to Neale’s (2004) suggestion. (shrink)

In “On Referring” Peter Strawson pointed out that incomplete descriptions pose a problem for Russell’s analysis of definite descriptions. Howard Wettstein and Michael Devitt appealed to incomplete descriptions to argue, first, that Russell’s analysis of definite descriptions fails, and second, that Donnellan’s referential/attributive distinction has semantic bite. Stephen Neale has defended Russell’s analysis of definite descriptions against Wettstein’s and Devitt’s objections. In this paper, my aim is twofold. First, I rebut Neale’s objections to (...) Wettstein’s and Devitt’s argument and argue that Neale’s attempt to provide an account of referential descriptions within a Russellian framework fails. Second, contra Devitt and Wettstein, I argue that the problem posed by incomplete descriptions shows that Donnellan was right in believing that referential descriptions refer even if the definite description fits nothing.

We investigate incomplete symbols, i.e. definite descriptions with scope-operators. Russell famously introduced definite descriptions by contextual definitions; in this article definite descriptions are introduced by rules in a specific calculus that is very well suited for proof-theoretic investigations. That is to say, the phrase ‘incomplete symbols’ is formally interpreted as to the existence of an elimination procedure. The last section offers semantical tools for interpreting the phrase ‘no meaning in isolation’ in a formal way.

The truth-table degree of the set of shortest programs remains an outstanding problem in recursion theory. We examine two related sets, the set of shortest descriptions and the set of domain-random strings, and show that the truth-table degrees of these sets depend on the underlying acceptable numbering. We achieve some additional properties for the truth-table incomplete versions of these sets, namely retraceability and approximability. We give priority-free constructions of bounded truth-table chains and bounded truth-table antichains inside the truth-table (...) complete degree by identifying an acceptable set of domain-random strings within each degree.

Critics and champions alike have fussed and fretted for well over fifty years about whether Russell’s treatment is compatible with certain alleged acceptable uses of incomplete definite descriptions,[2] where a description (the F( is incomplete just in case more than one object satisfies its nominal F, as in (1).

Bayesian models typically assume that agents are rational, logically omniscient and opinionated. The last of these has little descriptive or normative appeal, however, and limits our ability to describe how agents make up their minds (as opposed to changing them) or how they can suspend or withdraw their opinions. To address these limitations this paper represents the attitudinal states of non-opinionated agents by sets of (permissible) probability and desirability functions. Several basic ways in which such states of mind can be (...) changed are then characterised and compared with those found in AGM style models of attitude revision. Finally these models are employed to describe how agents make up their mind when deliberating. (shrink)

§1. Overview. Philosophers and mathematicians have drawn lots of conclusions from Gödel's incompleteness theorems, and related results from mathematical logic. Languages, minds, and machines figure prominently in the discussion. Gödel's theorems surely tell us something about these important matters. But what?A descriptive title for this paper would be “Gödel, Lucas, Penrose, Turing, Feferman, Dummett, mechanism, optimism, reflection, and indefinite extensibility”. Adding “God and the Devil” would probably be redundant. Despite the breath-taking, whirlwind tour, I have the modest aim of forging (...) connections between different parts of this literature and clearing up some confusions, together with the less modest aim of not introducing any more confusions.I propose to focus on three spheres within the literature on incompleteness. The first, and primary, one concerns arguments that Gödel's theorem refutes the mechanistic thesis that the human mind is, or can be accurately modeled as, a digital computer or a Turing machine. The most famous instance is the much reprinted J. R. Lucas [18]. To summarize, suppose that a mechanist provides plans for a machine,M, and claims that the output ofMconsists of all and only the arithmetic truths that a human, or the totality of human mathematicians, will ever or can ever know. We assume that the output ofMis consistent. (shrink)

Russell urged that some phrases having no meaning in isolation could nonetheless, Contribute to the meaning of sentences in which they occur. In the case of definite descriptive phrases, A proof is offered. It is argued that russell's proof is valid, Contrary to some commentators. Proper understanding of the notion of "incomplete symbol" plays a key role in the assessment of the argument, As well as in full appreciation of the radical departure of russell's analysis from "surface" grammar.

In lieu of an abstract, here is a brief excerpt of the content:Thomas G. Pavel INCOMPLETE WORLDS, RITUAL EMOTIONS' IN recent years, the notion of "fictional world" has enjoyed a considerable rise in fortune. The expression, however, is not entirely new. To refer to the world of a literary work, of a novel or of a play, has always been a favorite way of speaking for literary critics and aestheticians. In most cases, these were informal worlds. A discussion of (...) the world of Balzac, Dostoyevsky, HenryJames, or Proust often amounts to a description of each author's preferences in die selection and rearrangement of his material. Such discussion primarily fits authors who purposefully attempt to build comprehensive representational artifacts. One speaks quite naturally about l'univers balzacien, or about the universe of Musil. But is one entitled to refer with equal ease to the world ofBenjamin Constant, meagerly perceptible in his Adolphe, a short novel built in the spirit of economy, displaying just a few characters and a minimum of worldly information? Perhaps density and comprehensiveness are not indispensable characteristics of literary worlds. Aestheticians and narratologists using the "fictional worlds" terminology seem to believe mat any kind of artistic text projects a world, be it rich or poor. Such worlds are imagined in the fashion of modern philosophy of logic as states of affairs, more or less comprehensive. Some writers believe that the states of affairs comprised in fictional worlds must be fairly sizable, since diey should include "not only what the author indicates, but also whatever is required (entailed) by that which he indicates." 1 The laws of nature which are not specifically contradicted by the text would belong to its world. Thus, a few notorious cases aside, there is no reason to doubt that every child born in fiction has been engendered by a human fadier as long as the text does not report an exception. And if it does? Then, assuming that the laws of logic still govern if not fiction itself at least our understanding of it, we may appeal to what "possible world" philosophers have called "small miracles." * Editor's note: This article, as well as the contributions by Gerald Prince, Peter van Inwagen, and Kendall Walton which follow it, grew out ofa symposium on "Styles ofFictionality," organized by Professor Pavel and held at Harvard University in 1981. The Fall, 1983 issue of PHILOSOPHY AND LITERATURE will contain additional papers presented at the symposium. 48 Thomas G. Pavel49 Imagine, for instance, the world in which Notre Dame de Paris would be covered with blue paint. While everything else would preserve the properties it possesses in the actual world, with the laws of nature and the caused chains maintained, a small local change, somewhat miraculous, would modify only the color of the venerable building. Similarly, the world of Balzac may be understood as the world of early and mid-nineteenth-century France, slightly modified by the addition of a few hundred imagined characters. That diese conform surprisingly well to the general laws of French society of the time is so much the goal of Balzac's successful project, that for the sociologically-minded reader die' actual nonexistence of Rastignac, Rubempré, Vautrin, or Birotteau may appear a mere accident. These characters, one may surmise, display every trait that actual counterparts of theirs would possess, except existence. Hence, why would Rastignac's or Vautrin's emergence in a world omerwise identical to nineteenth-century France amount to anydiing more than a "small miracle"? On the other hand, Balzac's world being blessed wim hundreds of such miracles, the very magnitude of the project vindicates the attribute of "visionary," ascribed to Balzac by Béguin, or, if metaphorically undercut, mat of"God the Father" given him by Thibaudet. For, would not such magnitude entail more than just local changes in an otherwise faithful representation of the "actual" nineteenthcentury France? Similarly, would we interpret a fictional world in which a child has been engendered not by a human father, but by a divinity, as identical in all respects to the actual world, except for the limited modification attributed to a small miracle? 2 If we grant for a moment the improbable assumption that nineteenth-century France was a given and that Balzac...

Early in Principia Mathematica Russell presents an argument that "‘the author of Waverley’ means nothing", an argument that he calls a "definite proof". He generalizes it to claim that definite descriptions are incomplete symbols having meaning only in sentential context. This Principia "proof" went largely unnoticed until Russell reaffirmed a near-identical "proof" in his philosophical autobiography nearly 50 years later. The "proof" is important, not only because it grounds our understanding of incomplete symbols in the Principia programme, (...) but also because failure to understand it fully has been a source of much unjustified criticism of Russell to the effect that he was wedded to a naive theory of meaning and prone to carelessness and confusion in his philosophy of logic and language generally. In my paper, I (1) defend Russell’s "proof" against attacks from several sources over the last half century, (2) examine the implications of the "proof" for understanding Russell’s treatment of class symbols in Principia, and (3) see how the Principia notion of incomplete symbol was carried forward into Russell’s conception of philosophical analysis as it developed in his logical atomist period after 1910.

In a work that appeared in 1967 but which has lost none of its interest today, P. Alexandre gave a list of the 51 languages of Black Africa (or homogeneous dialectical and linguistic groups) that approached or surpassed a million speakers. For each of them he evaluated available documentation, on a scale of from 1 to 6. He gave the rating 1 to languages for which the documentation was poor (outdated grammars and dictionaries, incomplete or absurd systems of unscientific (...) transcription) and the rating 6 to languages for which works conforming to modern requirements were available (correctly noted sound systems, phonological and phonetic descriptions, annotated texts, dictionaries, stylistic and dialectological studies, audio material). Only three languages merited the rating 6 and only four were rated 5. This means that only seven languages out of about 1200 could be considered as accurately described, that is, offering all the necessary guarantees to the specialist. (shrink)

In his paper, “Descriptions, Indexicals, and Belief Reports: Some Dilemmas (But Not the Ones You Expect)” (Mind 104, (1995)), Stephen Schiffer presents a powerful argument against anyone who accepts a Russellian account of definite descriptions (including incomplete descriptions) and who also accepts a direct referential account of indexicals. On the one hand, the most plausible version of the Theory of Descriptions, namely, the Hidden-Indexical Theory of Descriptions, entails that a speaker who uses an (...) class='Hi'>incomplete description, “the F”, referentially means some description-theoretic, object-independent proposition by an utterance of a sentence of the form, “The F is G”. On the other hand, since speaker meaning supervenes on one’s psychological states, what holds for referential uses of incomplete descriptions must also hold for referential uses of indexicals and demonstatives. In other words, speakers who produce literal, referential, indexical utterances of the form, “" is G” also mean some description-theoretic proposition by their utterances. Furthermore, the Russellian has no non-arbitrary reason for preferring a direct referential account of indexicals, which he should accept, to a rival, incompatible account which treats indexicals as disguised descriptions. In my paper, I argue that the Russellian does have such a reason: the rival account cannot explain all the relevant speaker meaning facts that the direct reference theory can. I conclude the paper by defending the Russellian view that, in producing a referential utterance of “the F is G”, a speaker can mean a description-theoretic proposition and, in addition, mean an object-dependent proposition involving the speaker’s referent.

According to the received view, descriptivism is a dead end in an attempt to account for singular reference by proper names, indexicals and possibly even incomplete descriptions, for they require referentialism. In contrast to this, I argue for an application of the former to all kinds of singular terms, indexicals in particular, by relying on a view of incomplete descriptions as elliptical in a pragmatic sense. I thus provide a general analysis of singular reference. The proposed (...) approach is in line with the classical theory of propositions, except for admitting “private” ones with subjective mental entities as constituents. On the other hand, there is no commitment to singular Russellian propositions with ordinary objects as constituents and in general to meanings that cannot be “in the mind”. (shrink)

Various theories of referent are critically but briefly surveyed from the perspective of structural realism; a constructivist version of structural realist account of referent is outlined, and its implications for history of science and for descriptive metaphysics are briefly indicated.

A common objection to Russell's theory of descriptions concerns incomplete definite descriptions: uses of (for example) ‘the book is overdue’ in contexts where there is clearly more than one book. Many contemporary Russellians hold that such utterances will invariably convey a contextually determined complete proposition, for example, that the book in your briefcase is overdue. But according to the objection this gets things wrong: typically, when a speaker utters such a sentence, no facts about the context or (...) the speaker's communicative intentions single out a particular description-theoretic proposition as the proposition expressed. However, this is an objection only if it is assumed that successful linguistic communication requires the hearer to identify a proposition uniquely intended by the speaker. We argue that this assumption is mistaken. On our view, no proposition, descriptive or referential, is uniquely intended in such a context; thus, no proposition can nor need be identified as the proposition expressed. One significant upshot is that, once the aforementioned assumption is rejected, incompleteness no longer poses a threat to Russell's theory of descriptions. (shrink)

The normative principle of description invariance presupposes that rational preferences must be complete. The completeness axiom is normatively dubious, however, and its rejection opens the door to rational framing effects. In this commentary, we suggest that Bermúdez's insightful challenge to the standard normative view of framing can be clarified and extended by situating it within a broader critique of completeness.

The model of incomplete cooperative games incorporates uncertainty into the classical model of cooperative games by considering a partial characteristic function. Thus the values for some of the coalitions are not known. The main focus of this paper is 1-convexity under this framework. We are interested in two heavily intertwined questions. First, given an incomplete game, how can we fill in the missing values to obtain a complete 1-convex game? Second, how to determine in a rational, fair, and (...) efficient way the payoffs of players based only on the known values of coalitions? We illustrate the analysis with two classes of incomplete games—minimal incomplete games and incomplete games with defined upper vector. To answer the first question, for both classes, we provide a description of the set of 1-convex extensions in terms of its extreme points and extreme rays. Based on the description of the set of 1-convex extensions, we introduce generalisations of three solution concepts for complete games, namely the τ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\tau $$\end{document}-value, the Shapley value and the nucleolus. For minimal incomplete games, we show that all of the generalised values coincide. We call it the average value and provide different axiomatisations. For incomplete games with defined upper vector, we show that the generalised values do not coincide in general. This highlights the importance and also the difficulty of considering more general classes of incomplete games. (shrink)

The first aim of this paper is to elucidate Russell’s construction of spatial points, which is to be <br>considered as a paradigmatic case of the "logical constructions" that played a central role in his epistemology and theory of science. Comparing it with parallel endeavours carried out by Carnap and Stone it is argued that Russell’s construction is best understood as a structural representation. It is shown that Russell’s and Carnap’s representational constructions may be considered as incomplete and sketchy harbingers (...) of Stone’s representation theorems. The representational program inaugurated by Stone’s theorems was one of the success stories of 20th century’s mathematics. This suggests that representational constructions à la Stone could also be important for epistemology and philosophy of science. More specifically it is argued that the issues proposed by Russellian definite descriptions, logical constructions, and structural representations still have a place on the agenda of contemporary epistemology and philosophy of science. Finally, the representational interpretation of Russell’s logical constructivism is used to shed some new light on the recently vigorously discussed topic of his structural realism. (shrink)

Some contemporary semantic views defend an asymmetry thesis concerning defi-nite descriptions and indexicals. Semantically, indexicals are devices of singular refer-ence; they contribute objects to the contents of the speech acts made with utterances including them. Definite descriptions, on the other hand, are generalized quantifiers, behaving roughly the way Russell envisaged in “On Denoting”. The asymmetry thesis depends on the existence of a sufficiently clear-cut distinction between semantics and pragmatics, because indexicals and descriptions are often used in ways (...) that apparently contradict the asymmetry thesis; the semantics/pragmatics distinction is invoked to see behind the appearances. The paper critically examines arguments by Schiffer against the asymmetry thesis, based on referential uses of incomplete descriptions. (shrink)

One of the most important insights that Russell had in presenting his philosophy of language was his view of singular definite descriptions. Russell held that singular phrases of the form ‘the so-and-so’ should not be viewed as names, but rather incomplete symbols which can be said to have meaning only in a context. We should not represent the sentence The inventor of bifocals is bald.as a simple subject-predicate sentence of the form ‘Fa.’ but rather as a complex existential (...) sentence. According to Russell we should analyze as There is a unique x such that x invented bifocals and x is bald.Moreover, if Russell's analysis is correct then the proposition expressed by will be true in a given circumstance provided that there is a unique inventor of bifocals who is bald in that circumstance.

Despite its enormous popularity, Russell’s theory of definite descriptions has received various criticisms. Two of the most important objections against this theory are those arising from the Argument from Incompleteness and the Argument from Donnellan’s Distinction. According to the former although a speaker may say something true by assertively uttering a sentence containing an incomplete description , on the Russellian analysis such a sentence expresses a false proposition; so, Russell’s theory cannot adequately deal with such sentences. According to (...) the latter objection a descriptive sentence is actually ambiguous—it expresses a general proposition when the description contained in it is used attributively, and a singular proposition when the description in question is used referentially; Russell’s theory is inadequate as it fails to capture this ambiguity and offers an analysis according to which a descriptive sentence expresses only a general proposition. These objections are examined in the present dissertation. It is shown here that these objections arise from: (i) ignoring the distinction between the meaning of a sentence and the assertions made by using it, (ii) the failure to distinguish between the semantic meaning of a sentence and the pragmatic meaning with which it is used on a particular occasion. To make the distinction mentioned in (i), a significant part of Scott Soames’ theory concerning meaning and assertions has been adopted in this dissertation; and, to make the distinction mentioned in (ii), a test, namely the cancellability test, and two Distinguishing Criteria, namely DC-1 and DC-2, have been developed here. It has been argued here that if we properly make the relevant distinctions, then we will find that: (a) the phenomenon cited by the Argument from Incompleteness can be well explained keeping the Russellian analysis of descriptive sentences intact, (b) the phenomenon arising from the Argument from Donnellan’s Distinction raises an issue of pragmatics and is irrelevant to Russell’s semantic analysis of descriptive sentences. So, none of the above criticisms poses a genuine threat to Russell’s theory of definite descriptions; his theory actually provides, to a large extent, a correct semantic analysis of descriptive sentences.

We investigate a speci c model of knowledge and beliefs and their dynamics. The model is inspired by public announcement logic and the approach to puzzles concerning knowledge using that logic. In the model epistemic considerations are based on ontology. The main notion that constitutes a bridge between these two disciplines is the notion of epistemic capacities. Within the model we study scenarios in which agents can receive false announcements and can have incomplete or improper views about other agent's (...) epistemic capacities. Moreover, we try to express the description of problem speci cation using the tools from applied ontology { RDF format for information and the Protege editor. (shrink)

Russell claims in his autobiography and elsewhere that he discovered his 1905 theory of descriptions while attempting to solve the logical and semantic paradoxes plaguing his work on the foundations of mathematics. In this paper, I hope to make the connection between his work on the paradoxes and the theory of descriptions and his theory of incomplete symbols generally clearer. In particular, I argue that the theory of descriptions arose from the realization that not only can (...) a class not be thought of as a single thing, neither can the meaning/intension of any expression capable of singling out one collection (class) of things as opposed to another. If this is right, it shows that Russell’s method of solving the logical paradoxes is wholly incompatible with anything like a Fregean dualism between sense and reference or meaning and denotation. I also discuss how this realization lead to modifications in his understanding of propositions and propositional functions, and suggest that Russell’s confrontation with these issues may be instructive for ongoing research.

The existence of a transitive, complete, and weakly independent relation on the full set of gambles implies the existence of a non-Ramsey set. Therefore, each transitive and weakly independent relation on the set of gambles either is incomplete or does not have an explicit description. Whatever tools decision theory makes available, there will always be decision problems where these tools fail us. In this sense, decision theory remains incomplete.

This critical notice of Stephen Neale's "Descriptions", (MIT Press, 1990) summarizes the content of the book and presents several objections to its arguments, as well as praising Neale for showing just how close the linguistic notion of L F is to the analytic philosopher's notion of "logical form". It is claimed that Neale's use of generalized quantifiers to represent definite descriptions from Russell's account by which descriptions are "incomplete symbols".

_ Source: _Volume 53, Issue 2-4, pp 221 - 248 One of the peculiarities of Peter Abelard’s analysis of incomplete and non-assertive sentences is his use of the notion of desire: in both _Dialectica_ and _Glosses on Peri hermeneias_ the terms _desiderium_ and _desidero_ move to the foreground side by side with _optatio, expectatio, suspensio_ and the related verbs. Desire plays a structural role in Abelard’s descriptions of the compositional way in which the linguistic message is received, changing (...) step by step from incomplete to complete: the person who receives the incomplete message desires to get further information through other words since he knows that the purpose of such words or sequences of words is to combine with other words in order to form a complete sentence. On the other hand, the expression of the speaker’s attention to his inner affections renders the same semantic content a different complete sentence. (shrink)

One of Strawson's objections to Russell's theory of descriptions is that what are intuitively natural and correct utterances of sentences involving incomplete descriptions come out false by RTD. Russellians have responded, not by challenging Strawson's view that these uses are natural and correct, but by embellishing RTD to accommodate these uses. I pursue an alternative line of attack: I argue that there are circumstances in which "we" would find utterances of such sentences unnatural and improper but "RTD" (...) would sanction. So, RTD clashes with ordinary language, as Strawson suggests. (shrink)

The article aims to demonstrate that the nudge theory suffers from three main weaknesses stemming from its theoretical dependence on behavioural economics. The first two weaknesses endanger the paternalistic goal, whereas the third does not justify the libertarian attribute. The first weakness lies in the incomplete realistic characterisation of behavioural economics theory that is the central theoretical pillar of Nudge theory. The second weakness is even more relevant. The normative model of behavioural economics is neoclassical rationality. It can be (...) applied to choices in conditions of risk, when it is possible to forecast the probability of the outcomes of one’s choices. On the contrary the real life problems are inside a complex and uncertain environment. In an uncertain environment the neoclassical algorithms are no longer valid, in that they postulate the knowledge of the probability of the outputs. Thus errors and bias, as observed in behavioural economics, are not such in many instances, but they are instead adaptive and therefore rational responses to the context of decision-making. Therefore nudge theory that pursues the normative paternalistic objective of neutralising the bias and judgement errors discovered by behavioural economics and putting paternalistically the citizen on the right track, is in fact proceeding in the wrong direction. The last weakness concerns an assumption of Nudge theory about the duality of mind. System 1 represents the intuitive mind, while System 2 corresponds to the analytical one. System 1 tends to make decisions quickly and unconsciously, while System 2 follows a slow and conscious process. Biases and judgement errors are mainly generated by System 1. However, System 2 may later intervene to correct them. From this premise, the Nudge theory affirms its libertarian character. In this paper I will argue that the dualism of the mind would not entail the reversibility of some nudges, particularly of default states. In this way the fundamental pillar is weakened to justify the libertarian character of the nudge theory. (shrink)

1. ExpositionRichard Sharvy's ‘A more general theory of definite descriptions’ was published in 1980. Its aim was to replace Russell's paradigm by " a general theory of definite descriptions, of which definite mass descriptions, definite plural descriptions, and Russellian definite singular count descriptions are species. … We have an account of the generic ‘the’ along these same lines. " By now his theory has attained the status of a new paradigm. Even a casual trawl of (...) the literature throws up over a score of citations and endorsements, and no rebuttals of its central contention that the primary use of ‘the’ is to indicate totality . We shall argue that it is wrong for mass description, wrong for singular description, wrong for plural description and wrong for generic ‘the’. Sharvy would have approved: his obituary says that his car displayed the slogan ‘Subvert the Dominant Paradigm’.He follows Russell in treating descriptions as incomplete symbols, but nothing in his paper turns on this aspect of it, and we can bypass the issue by considering them in the context of complete sentences. Where Russell translates F into the predicate calculus as Formula Sharvy translates it as Formula Here ≤ is supposed to stand for some or other species of part of relation. His other governing idea is of a predicate's being cumulative. G is cumulative if any number of things that satisfy G have a sum, i.e. a least upper bound with respect to ≤ which also satisfies G. The meanings of ≤, sum and cumulativity vary according to the different kinds of description, which we take in the order in which Sharvy presents them. Meanwhile, we note that he originally defined ‘sum’ to mean simply the l.u.b. , but subsequently redefined …. (shrink)
