Normality judgements are frequently used in everyday communication as well as in biological and social science. Moreover they became increasingly relevant to formal logic as part of defeasible reasoning. This paper distinguishes different kinds of normality statements. It is argued that normality laws like “Birds can normally fly” should be understood essentially in a statistical way. The argument has basically two parts: firstly, a statistical semantic core is mandatory for a descriptive reading of normality in (...) order to explain the logical features of normality laws. Secondly, a statistical justification of normality statements can be derived by game theoretic considerations if the normality law is understood as communication convention. (shrink)

We discuss the content and significance of John von Neumann’s quantum ergodic theorem (QET) of 1929, a strong result arising from the mere mathematical structure of quantum mechanics. The QET is a precise formulation of what we call normal typicality, i.e., the statement that, for typical large systems, every initial wave function ψ0 from an energy shell is “normal”: it evolves in such a way that |ψt ψt| is, for most t, macroscopically equivalent to the micro-canonical density matrix. The QET (...) has been mostly forgotten after it was criticized as a dynamically vacuous statement in several papers in the 1950s. However, we point out that this criticism does not apply to the actual QET, a correct statement of which does not appear in these papers, but to a different (indeed weaker) statement. Furthermore, we formulate a stronger statement of normal typicality, based on the observation that the bound on the deviations from the average specified by von Neumann is unnecessarily coarse and a much tighter (and more relevant) bound actually follows from his proof.

The five English words—sentence, proposition, judgment, statement, and fact—are central to coherent discussion in logic. However, each is ambiguous in that logicians use each with multiple normal meanings. Several of their meanings are vague in the sense of admitting borderline cases. In the course of displaying and describing the phenomena discussed using these words, this paper juxtaposes, distinguishes, and analyzes several senses of these and related words, focusing on a constellation of recommended senses. One of the purposes of this paper (...) is to demonstrate that ordinary English properly used has the resources for intricate and philosophically sound investigation of rather deep issues in logic and philosophy of language. No mathematical, logical, or linguistic symbols are used. Meanings need to be identified and clarified before being expressed in symbols. We hope to establish that clarity is served by deferring the extensive use of formalized or logically perfect languages until a solid “informal” foundation has been established. Questions of “ontological status”—e.g., whether propositions or sentences, or for that matter characters, numbers, truth-values, or instants, are “real entities”, are “idealizations”, or are “theoretical constructs”—plays no role in this paper. As is suggested by the title, this paper is written to be read aloud. -/- I hope that reading this aloud in groups will unite people in the enjoyment of the humanistic spirit of analytic philosophy.

This paper uses the intuition from the game of chickento model client-auditor financial reporting and audit effort strategies. Within an ethical context, our model is concerned with the client misreporting and its detection by the auditor. The paper uses a welfare game(similar to the game of chicken) to more formally model client-auditor strategies. The welfare game is then extended to provide additional insight into ethical and audit effort issues.Such a welfare gameprovides equilibrium in mixed strategies. This mixed strategy solution makes (...) possible four outcomes from the game: 1) Financial Statements are fairly presented by client and the auditor performs a normal audit, 2) Financial Statements are fairly presented by client and the auditor performs an extended audit (over auditing), 3) Financial State-ments are misstated by client and detected by the auditor, and 4) Financial Statements are misstated by client and not detected by the auditor (audit failure despite no intended unethical action on the part of the auditor).

A deficit in the number of organs available for transplantation persists even with an increase in donation rates. One possible choice of donor for organs that appears under-referred and/or unaccepted is patients with primary brain tumours. In spite of advances in the treatment of high-grade primary central nervous system (CNS) tumours, the prognosis remains dire. A working group on organs from donors with primary CNS tumours showed that the risk of transmission is small and outweighs the benefits of waiting for (...) a normal donor, in survival and organ life-years, with caveats. This paper explores the possibility that, if information on organ donation were made available to patients and their families with knowledge of their inevitable fate, perhaps some will choose to donate. It would be explained that to achieve this, elective ventilation would be performed in their final moments. This would obviate the consent question because of an advance statement. It is accepted that these are sensitive matters and there will be logistic issues. This will need discussion with the public and other professionals, but it could increase the number of donors and can be extrapolated to encompass other primary CNS tumours. (shrink)

An overcomplete logic is a logic that ‘ceases to make the difference’: According to such a logic, all inferences hold independently of the nature of the statements involved. A negation-inconsistent logic is a logic having at least one model that satisfies both some statement and its negation. A negation-incomplete logic has at least one model according to which neither some statement nor its negation are satisfied. Paraconsistent logics are negation-inconsistent yet non-overcomplete; paracomplete logics are negation-incomplete yet non-overcomplete. A paranormal (...) logic is simply a logic that is both paraconsistent and paracomplete. -/- Despite being perfectly consistent and complete with respect to classical negation, nearly every normal modal logic, in its ordinary language and interpretation, admits to some latent paranormality: It is paracomplete with respect to a negation defined as an impossibility operator, and paraconsistent with respect to a negation defined as non-necessity. In fact, as it will be shown here, even in languages without a primitive classical negation, normal modal logics can often be alternatively characterized directly by way of their paranormal negations and related operators. So, instead of talking about ‘necessity’, ‘possibility’, and so on, modal logics could be seen just as devices tailored for the study of (modal) negation. This paper shows how and to what extent this alternative characterization of modal logics can be realized. (shrink)

David Mermin suggests that my recent proof pertaining to quan tum nonlocality is undermined by an essential ambiguity pertaining to the meaning of counterfactual statements in quantum physics The ambiguity he cites arise from his imposition of a certain criterion for the meaningfulness of such counterfactual statements That criterion con ates the meaning of a counterfactual statement with the details of a proof of its validity in such a way as to make the meaning of such a statement (...) dependent upon the context in which it occurs That dependence violates the normal demand in logic that the meaning of a statement be de ned by the words in the statement itself not by the context in which the statement occurs My proof conforms to that normal requirement I describe the context independent meaning within my proof of the counterfactual statements in question..

This paper discusses critically the fundamental elements of the Stegmüller/Sneed-reconstruction of Kuhn's normal science concept. It is argued that a) Kuhn himself cannot accept this reconstruction if he wants to describe theory dynamics in the past; b) the reconstruction is not based on a pure non-statement view; c) to have a theory in the sense of Kuhn, should be related to the ordered pair <K,Iₒ> to ensure the desired constancy over time; d) the reconstruction implies, contrary to Kuhn, the ability (...) of rejecting a theory without having an alternative one; e) the rejection of a theory can be the result of a falsifying procedure and, therefore, theories are not immune from falsification; f) the reconstruction still contains rationality gaps; g) the reconstruction shows more precisely than Kuhn's work that Popper is right when he attacks normal scientist's behaviour; h) the positions of the Kuhnians and of the criticists could be reconciled partially.

In previous work, the author has shown that $\Pi ^1_1$ -induction along $\mathbb N$ is equivalent to a suitable formalization of the statement that every normal function on the ordinals has a fixed point. More precisely, this was proved for a representation of normal functions in terms of Girard’s dilators, which are particularly uniform transformations of well orders. The present paper works on the next type level and considers uniform transformations of dilators, which are called 2-ptykes. We show that $\Pi (...) ^1_2$ -induction along $\mathbb N$ is equivalent to the existence of fixed points for all 2-ptykes that satisfy a certain normality condition. Beyond this specific result, the paper paves the way for the analysis of further $\Pi ^1_4$ -statements in terms of well ordering principles. (shrink)

Three variants of Beth's definability theorem are considered. Let L be any normal extension of the provability logic G. It is proved that the first variant B1 holds in L iff L possesses Craig's interpolation property. If L is consistent, then the statement B2 holds in L iff L = G + {0}. Finally, the variant B3 holds in any normal extension of G.

Michael Rathjen and the present author have shown that ‐bar induction is equivalent to (a suitable formalization of) the statement that every normal function has a derivative, provably in. In this note we show that the base theory can be weakened to. Our argument makes crucial use of a normal function f with and. We shall also exhibit a normal function g with and.

Carnap in the 1930s discovered that there were non-normal interpretations of classical logic - ones for which negation and conjunction are not truth-functional so that a statement and its negation could have the same truth value, and a disjunction of two false sentences could be true. Church ar-gued that this did not call for a revision of classical logic. More recent writers seem to disa-gree. We provide a definition of "non-normal interpretation" and argue that Church was right, and in fact, (...) the existence of non-normal interpretations tells us something important about the condi-tions of extensionality of the classical logical operators.

Suppose $\kappa$ is a supercompact cardinal and $\lambda > \kappa$. We study the relationship between the partition property and the weak partition property for normal ultrafilters on $P_\kappa\lambda$. On the one hand, we show that the following statement is consistent, given an appropriate large cardinal assumption: The partition property and the weak partition property are equivalent, there are many normal ultrafilters that satisfy these properties, and there are many normal ultrafilters that do not satisfy these properties. On the other hand, (...) we consider the assumption that, for some $\lambda > \kappa$, there exists a normal ultrafilter $U$ on $P_\kappa\lambda$ such that $U$ satisfies the weak partition property but does not satisfy the partition property. We show that this assumption is implied by the assertion that there exists a cardinal $\gamma > \kappa$ such that $\gamma$ is $\gamma^+$-supercompact, and, assuming the GCH, it implies the assertion that there exists a cardinal $\gamma > \kappa$ such that $\gamma$ is a measurable cardinal with a normal ultrafilter concentrating on measurable cardinals.

In a recent paper by M. Rathjen and the present author it has been shown that the statement “every normal function has a derivative” is equivalent to $\Pi ^1_1$ -bar induction. The equivalence was proved over $\mathbf {ACA_0}$, for a suitable representation of normal functions in terms of dilators. In the present paper, we show that the statement “every normal function has at least one fixed point” is equivalent to $\Pi ^1_1$ -induction along the natural numbers.

Bourdieu’s concept of ‘symbolic capital’ has been used to study various kinds of elites. This article shows how it can help us understand the status and privileges of early modern English courtiers—and how these could be won and lost. The discussion focuses on the funeral, burial and commemoration of the most successful of contemporary generals, Charles Blount, 1st Earl of Devonshire, 8th Baron Mountjoy (1563–1606), and sets these in the context of the Jacobean court’s concern with symbolic capital. It demonstrates (...) that the ceremonies normally accorded someone of Mountjoy’s rank and military success were not observed properly. He was penalised because he had married his long-standing lover, Lady Penelope Rich (1563–1607), the ‘Stella’ of Sir Philip Sidney’s sonnets. King James I showed the couple great favour until their marriage, which he declared unlawful and annulled. The heralds accepted his ruling, after disagreeing among themselves. The article shows that though the funeral was held in Westminster Abbey, Mountjoy was not buried there but in another London church, formerly known as Greyfriars, where a monument was erected to him. Lady Rich was personally and symbolically excluded from the funeral. Also discussed is the privately printed poem that Mountjoy’s client Samuel Daniel (1562–1619) wrote for the funeral, which defends Mountjoy and alludes, in a half-hidden way, to Penelope’s exclusion. The article concludes by considering how the symbolic capital of the whole court sank in this period. Most of the archival evidence considered has not been published before, some of it illustrated in figures, the rest in appendices (an armorial description of Mountjoy’s arms at his funeral, bills from the Westminster Abbey funeral and a translated extract from a contemporary history in Latin).

In lieu of an abstract, here is a brief excerpt of the content:Sophistics, Rhetorics, and Performance; or, How to Really Do Things with WordsBarbara CassinTranslated by Andrew Goffey"How to do things with words?" How can you really do things with nothing but words? It seems to me that sophistics is in a way the paradigm of discourse that does things with words. Doubtless it is not a "performative" in Austin's sense of the word, although Austin's sense varies considerably in extension (...) and intension. But it is for real a discourse that operates, that transforms or creates the world, and has what I call a "world effect."Making the connection with performativity is all the more tempting, as epideixis, the word that serves in Plato to designate sophist discourse, cannot be rendered better than by "performance," on condition that "performance" is also understood in the sense of contemporary aesthetics as a "happening," an "event," an improvisation that requires engagement (Gorgias is the inventor of discourse ex tempore, according to Philostratus)—something like an "exploit."1"Performative" is Austin's own invention, acclimated to French by Austin himself at a colloquium held at Royaumont (Austin 1962); thereafter it was immediately adopted and popularized by Émile Benveniste (1966). "Performance" is a much older term, which, after ceaseless borrowings to and fro between English and French, has seen its meaning shifted and extended accordingly. Klein's Comprehensive Etymological Dictionary of English Language (Klein 1971) maintains that in English "performer" [End Page 349] was coined from Old French parfournir (from medieval Latin perfurnire) and/or parformer; in addition French borrowed the term at least three times, if the Dictionnaire culturel de la langue francaise (Rey 2005) is to be believed: in 1869, by analogy with the vocabulary of horse races to mean the "manner of developing a subject, of executing a work in public"; in 1953, to denote "individual result in the accomplishment of a task"; and in 1963, in the wake of Chomsky, to mean the opposite of "competence." In sum, the word is a fluid, bilingual term that bridges sport (performance in the sense of a record), technique (performance in the sense of the output of a machine), psychology (performance of a test), linguistics (performance/competence), and modern art (performance in the sense of happening).Let us start with the relationship between performance and performative. It is a way to interrogate the status of rhetorics, for which Austin, without naming it, reserves a somewhat unstable place between the "locutionary" on the one hand and the "illocutionary" or performative on the other, calling it the "perlocutionary" ("per" precisely as in "performative").2But it is not of Austin that I will speak. Austin is simply the contemporary frame of reference that informs us today: he "invented" the performative as such for us, by trying to isolate it. And he never hides the difficulty, the permeability, of his taxonomy. Just one citation is enough to show the difficulty. In the seventh lecture of the twelve that make up How to Do Things with Words (quite late then) he writes: "It is time [...] to make a fresh start on the problem. We want to reconsider more generally the senses in which to say something may be to do something, or in saying something we do something (and also perhaps to consider the different case in which by saying something we do something). Perhaps some clarification and definition may help us out of our tangle. For after all, 'doing something' is a very vague expression. When we issue any utterance whatsoever, are we not 'doing something'?" (1975, 91–92).In the framework of the generalized theory of speech acts, the difference between the locutionary, the illocutionary, and the perlocutionary has for a long time been in a "tangle". It is not so easy to differentiate between the three. All three are, precisely, "acts" of language, and without doubt the categories are at once abstract, slippery, and overlapping. The "locutionary" or "constative," a "normal" statement, is an utterance that "says something"; it is an "act of saying something" (1975, 100): "The cat is on the mat" has a meaning (both a "sense" and a "reference") and is susceptible of being either true or false.

Under normal circumstances, saying that you have a thought, a belief, a desire, or an intention differs from saying that somebody (who happens to be you) has that attitude. The former statement comes with some form of first person authority and constitutes commitments that are not involved in the latter case. Speaking with first person authority, and thereby publicly committing oneself, is a practice that plays an important role in our communication and in our understanding of what it means to (...) be a person. In their Group Agency, Christian List and Philip Pettit argue that some corporations are agents with attitudes of their own, and they claim that they are persons. The question on which this paper is focused is: Can corporations (groups with attitudes and the capacity for linguistic communication) participate in this practice, that is, can they express their attitudes with first person authority, and thereby enter first person commitments? The first section of the paper gives a rough (and, I hope, ecumenical) account of some features of first person authority and commitment. The second section examines if and how this account of first person authority carries over to corporations. It is argued that the possibility for groups to express their attitudes with straightforward first person authority, and thus to enter first person commitments, are extremely limited. The third part of the paper argues that while under normal circumstances, a member’s expression of her group’s attitudes in first person plural terms does not constitute straightforward first person authority, it does come with something resembling some aspects of the first-personal commitments encountered in the singular case.

We say that things happen accidentally when they do indeed happen, but only by chance. In the opposite situation, an essential happening is inescapable, its inevitability being the sine qua non for its very occurrence. This paper will investigate modal logics on a language tailored to talk about essential and accidental statements. Completeness of some among the weakest and the strongest such systems is attained. The weak expressibility of the classical propositional language enriched with the non-normal modal operators of (...) essence and accident is highlighted and illustrated, both with respect to the definability of the more usual modal operators as well as with respect to the characterizability of classes of frames. Several interesting problems and directions are left open for exploration. (shrink)

Mathematical statements arising from program verification are believed to be much easier to deal with than statements coming from serious mathematics. At least this is true for “normal programming”.

The first part is dedicated to the different accounts on secularization that may be applied to European countries: the classical Weber theory that view secularization as an “iron law” of any society, the institutional secularization, secularization as the decline and adequacy of religious practice, the continuation of the classical theory in the 60’s and beyond, the criticism of this theory and the particular argument of the increase of fundamentalist religious movements. The attempts to formulate new theories on secularization based on other assumptions than the classical one are also presented. The increased presence of religion in private life does not mean a decrease of religion in the public space but rather a new definition of it. Despite the different intensity of belief in national terms, some trends like “believing without belonging” are common, meaning that secularization could have a single meaning in Europe, apart from other continents. The second part starts with presenting the three types of Church - State relationship at the national level. All these have in common the fact that the state is neutral towards religious subjects, a religious subsection is singled out within the public sphere and the state has the right to intervene in this area only as an arbiter. There is already a European law on religion and this statement is supported by examples from the Lisbon Treaty, The Charter of Fundamental Rights, different Directives and decisions of the European Court of Justice. Common rules on religion agreed at the European level helps better to understand why there is a common European model on religions, different from the national models. After taking into account the two aspects described above, a common European model on religion in the public sphere emerges as a necessary conclusion. (shrink)

Many books explain what is known about the universe. This book investigates what cannot be known. Rather than exploring the amazing facts that science, mathematics, and reason have revealed to us, this work studies what science, mathematics, and reason tell us cannot be revealed. In The Outer Limits of Reason, Noson Yanofsky considers what cannot be predicted, described, or known, and what will never be understood. He discusses the limitations of computers, physics, logic, and our own thought processes. Yanofsky describes (...) simple tasks that would take computers trillions of centuries to complete and other problems that computers can never solve; perfectly formed English sentences that make no sense; different levels of infinity; the bizarre world of the quantum; the relevance of relativity theory; the causes of chaos theory; math problems that cannot be solved by normal means; and statements that are true but cannot be proven. He explains the limitations of our intuitions about the world -- our ideas about space, time, and motion, and the complex relationship between the knower and the known. Moving from the concrete to the abstract, from problems of everyday language to straightforward philosophical questions to the formalities of physics and mathematics, Yanofsky demonstrates a myriad of unsolvable problems and paradoxes. Exploring the various limitations of our knowledge, he shows that many of these limitations have a similar pattern and that by investigating these patterns, we can better understand the structure and limitations of reason itself. Yanofsky even attempts to look beyond the borders of reason to see what, if anything, is out there. (shrink)

I have two basic goals in this paper. The one is to suggest that in thinking about objections to presentism, it is useful to structure those objections in a certain way. The second is then to set out, and evaluate, objections to presentism, and to show that presentism is untenable. -/- My discussion is organized as follows. In section 1, I briefly distinguish between two very different varieties of presentism, on only one of which I shall focus here. In section (...) 2, I discuss how presentism is best defined. That discussion is inconclusive, but I am inclined to recommend a different characterization of presentism than is normally offered. -/- Sections 3 through 9 are then concerned with objections to presentism. In section 3, I refer briefly to tenseless objections to all tensed views, including presentism, and to one central objection in particular that I think is very important. But I do not attempt either to answer that objection, or to support it, in this paper. In section 4, I discuss four objections to presentism that seem to me either problematic or unconvincing as they are ordinarily stated. I shall also consider, however, whether some of these objections can be reinstated. In discussing, in section 4, a version of the truthmaker objection set out by David Armstrong, I suggest that, in thinking about objections to presentism, it is best to divide up sentences about the past in a certain way, and my brief statement, in section 5, of what I take to be the crucial objections to presentism, is organized along those lines. In sections 6 and 7, I set out two objections to tensed-facts presentism that are concerned with general propositions about the past that do not involve cross-temporal relations, and that are not expressed by sentences that contain proper names. The first of these objections is concerned with the meaning of statements about the past or about the future; the second is the truthmaker objection. -/- Section 8 is then concerned with objections to tensed-facts presentism that focus upon cross-temporal relations. Here I argue that it is the relation of causation that is crucial. -/- In section 9, I then turn to the question of whether sentences containing names of individuals that no longer exist pose an additional, independent problem for tensed-facts presentism.

A ‘should’ question normally signals work for an ethicist but this ethicist’s task is complicated by the normative dimension of all the chapters in this volume. Each author was asked to come up with three recommendations from their own subject area – ’should’ statements deriving from the ‘is’ analysis that they present. If those prescriptions cover the relevant topics, what more is there for an ethicist to do? I have had a personal interest in obstetricians’ relationship with ‘older women’ (...) since being classified as an ‘elderly primigravida’ at the superannuated age of 26 years. Apart from that, however, what original contribution can I make? The convenors of the 56th RCOG Study Group gave me plentiful suggestions – perhaps a little too plentiful: How should the RCOG approach its constituencies, medical ethics, regulation and its relationship to government and the rest of the medical profession, i.e. the NHS and the market, vested interests, individuals or consumers, families, the unborn, doctors, drug companies, surrogacy, the unborn, trafficking, global adoption, law, research? I have to admit this was just too much for me. Instead, I want to argue for what may seem a self-evidently simple point. The RCOG describes its mission as ‘setting standards to improve women’s health’ – presumably all women. In the 6 years that I have served on the RCOG Ethics Committee, however, we have almost always been concerned with that minority of the female population who are of reproductive age. (shrink)

This study investigated eye-movement patterns during emotion perception for children with hearing aids and hearing children. Seventy-eight participants aged from 3 to 7 were asked to watch videos with a facial expression followed by an oral statement, and these two cues were either consistent or inconsistent in emotional valence. Results showed that while normal-hearing children paid more attention to the upper part of the face, children with hearing aids paid more attention to the lower face after the oral statement was (...) presented. When there was an inconsistency between the visual and auditory cues, children with hearing aids were likely to increase attention to the upper face. The results revealed the underlying mechanism of deficits in emotion perception for hearing-impaired children. (shrink)

Dynamic Epistemic Logic (DEL) deals with the representation and the study in a multi-agent setting of knowledge and belief change. It can express in a uniform way epistemic statements about: 1. what is true about an initial situation 2. what is true about an event occurring in this situation 3. what is true about the resulting situation after the event has occurred. We axiomatize within the DEL framework what we can infer about (iii) given (i) and (ii). Given three (...) formulas φ,φ' and φ" describing respectively (i), (ii) and (iii), we also show how to build a formula φ ? φ' which captures all the information which can be inferred about (iii) from φ and φ'. We show how our results extend to other modal logics than K. In our proofs and definitions, we resort to a large extent to the normal form formulas for modal logic originally introduced by Kit Fine. In a companion paper (Aucher, 2012), we axiomatize what we can infer about (ii) given (i) and (iii), and what we can infer about (i) given (ii) and (iii), and show how to build two formulas φ ? φ" and φ' ? φ" which capture respectively all the information which can be inferred about (ii) from φ and φ", and all the information which can be inferred about (i) from φ' and φ".

Bentham's critical statements on the Declaration of Human Rights of the French revolutionaries are supposed to be merely of historical value, as directed against a dated formulation. Against this, it is argued that the essential point of Bentham's argument is valid against any intuitivist interpretation of human rights (that is, against interpretations that take human rights as ultimate, absolute data) but are agreeable with an interpretation that takes Human Rights to be preferred lines of action that are normally conducive (...) to the greatest general hapiness.

Our normal discourse is replete with discussion of things which do not exist — the objects of fiction, of illusion and hallucination, of religious worship, of misguided fears and other intentional states. Let us call such discourse empty. How to account for the meaning of empty discourse, and such truth values as its statements have, are perennial and thorny philosophical topics. Many positions are well known; in this book of five chapters Azzouni advocates another. Empty discourse is literally about (...) nothing; nonetheless, one may give an account of how its sentences are both meaningful and have appropriate truth values. In the first three chapters, the ideas are applied to the objects of mathematics, hallucination, and fiction, respectively. Chapter 5 fills out the picture with a discussion of truth-conditional semantics. Chapter 4 broaches the question of how all this is relevant to a broader question: the unity of the sciences.The book is ingenious and clearly argued.1 There are many perceptive discussions — for example, of the way we talk about fictional objects, and about hallucination. And although it is not the main aim of the book, it mounts a number of telling arguments against alternative positions. And even if the book did not persuade at least this reader of its main thesis, it has estabished a genuinely novel and intriguing position …. (shrink)

In this article, Lucas maintains the falseness of Mechanism - the attempt to explain minds as machines - by means of Incompleteness Theorem of Gödel. Gödel’s theorem shows that in any system consistent and adequate for simple arithmetic there are formulae which cannot be proved in the system but that human minds can recognize as true; Lucas points out in his turn that Gödel’s theorem applies to machines because a machine is the concrete instantiation of a formal system: therefore, for (...) every machine consistent and able of doing simple arithmetic, there is a formula that it can’t produce as true but that we can see to be true, and so human minds and machines have to be different. Lucas considers as well in this article some possible objections to his argument: for any Gödelian formula we could, for instance, construct a machine able to produce it or we could put the Gödelian formulae that we had proved as axioms of a further machine. However - as Lucas underlines - for every of such machines we could again formulate another Gödelian formula, the Gödelian formula of these machines, that they are not able to proof but that we can recognize as true. More general arguments, such as the possibility to escape Gödelian argument by suggesting that Gödel’s theorem applies to consistent systems while we could be inconsistent ones, are moreover refuted by Lucas by maintaining that our inconsistency corresponds to occasional malfunctioning of a machine and not to his normal inconsistency; indeed, a inconsistent machine is characterized by producing any statement, on the contrary human being are selective and not disposed to assert anything.

Defeasible conditionals are statements of the form ‘if A then normally B’. One plausible interpretation introduced in nonmonotonic reasoning dictates that ) is true iff B is true in ‘most’ A-worlds. In this paper, we investigate defeasible conditionals constructed upon a notion of ‘overwhelming majority’, defined as ‘truth in a cofinite subset of \’, the first infinite ordinal. One approach employs the modal logic of the frame \\), used in the temporal logic of discrete linear time. We introduce and (...) investigate conditionals, defined modally over \\); several modal definitions of the conditional connective are examined, with an emphasis on the nonmonotonic ones. An alternative interpretation of ‘majority’ as sets cofinal ) rather than cofinite ) is examined. For these modal approaches over \\), a decision procedure readily emerges, as the modal logic \ of this frame is well-known and a translation of the conditional sentences can be mechanically checked for validity; this allows also for a quick proof of \-completeness of the satisfiability problem for these logics. A second approach employs the conditional version of Scott-Montague semantics, in the form of \-many possible worlds, endowed with neighborhoods populated by collections of cofinite subsets of \. This approach gives rise to weak conditional logics, as expected. The relative strength of the conditionals introduced is compared to KLM logics and other conditional logics in the literature.

This paper argues that the medical conception of health as absence of disease is a value-free theoretical notion. Its main elements are biological function and statistical normality, in contrast to various other ideas prominent in the literature on health. Apart from universal environmental injuries, diseases are internal states that depress a functional ability below species-typical levels. Health as freedom from disease is then statistical normality of function, i.e., the ability to perform all typical physiological functions with at least (...) typical efficiency. This conception of health is as value-free as statements of biological function. The view that health is essentially value-laden, held by most writers on the topic, seems to have one of two sources: an assumption that health judgments must be practical judgments about the treatment of patients, or a commitment to "positive" health beyond the absence of disease. I suggest that the assumption is mistaken, the commitment possibly misdescribed. (shrink)

A recent consensus statement claimed that double effect can justify induction of labor before viability when life-threatening pathological complications arise from the interaction of a normally functioning placenta with the diseased heart of the mother. The authors of this essay agree. They analyze two pieces published in response, using the framework of the first and fourth criteria of double effect; identify and attempt to clarify inaccuracies and other sources of ambiguity in the discussion; and acknowledge practical implications for other scenarios (...) previously considered illicit. They conclude that more thorough medical and moral discussion is needed regarding the fourth criterion, even if the act itself is not intrinsically evil.

Intuitionistic logic provides an elegant solution to the Sorites Paradox. Its acceptance has been hampered by two factors. First, the lack of an accepted semantics for languages containing vague terms has led even philosophers sympathetic to intuitionism to complain that no explanation has been given of why intuitionistic logic is the correct logic for such languages. Second, switching from classical to intuitionistic logic, while it may help with the Sorites, does not appear to offer any advantages when dealing with the (...) so-called paradoxes of higher-order vagueness. We offer a proposal that makes strides on both issues. We argue that the intuitionist’s characteristic rejection of any third alethic value alongside true and false is best elaborated by taking the normal modal system S4M to be the sentential logic of the operator ‘it is clearly the case that’. S4M opens the way to an account of higher-order vagueness which avoids the paradoxes that have been thought to infect the notion. S4M is one of the modal counterparts of the intuitionistic sentential calculus and we use this fact to explain why IPC is the correct sentential logic to use when reasoning with vague statements. We also show that our key results go through in an intuitionistic version of S4M. Finally, we deploy our analysis to reply to Timothy Williamson’s objections to intuitionistic treatments of vagueness. (shrink)

In Law’s Empire, Ronald Dworkin introduces an important distinction between what he calls the ‘grounds’ and the ‘force’ of law. The former primarily interest Dworkin in LE and concern the “circumstances in which particular propositions of law should be taken to be sound or true.” (110) Propositions of law, we are told, are “all the various statements and claims people make about what the law allows or prohibits or entitles them to have.” (4) That Canadians owing income tax to (...) the federal government must file their returns before April 30 or face a late penalty is presumably an example of a proposition of law. That the United States constitution prohibits slavery is another. These (true) propositions of law simply report the law’s (present) requirements, requirements which normally should be respected but which might justifiably be disobeyed or disregarded in exceptional cases. A true proposition of law, then, does not necessarily entail an answer to the question: What should I do, or decide (if called upon to render a judicial decision)? It also does not necessarily entail an answer to the question: Should the coercive power of the state be exercised against this person? (shrink)

In recent years there has been a resurgence of interest in Ethical Intuitionism, whose core claim is that normal ethical agents can and do have non-inferentially justified first-order ethical beliefs. Although this is the standard formulation, there are two senses in which it is importantly incomplete. Firstly, ethical intuitionism claims that there are non-inferentially justified ethical beliefs, but there is a worrying lack of consensus in the ethical literature as to what non-inferentially justified belief is. Secondly, it has been overlooked (...) that there are plausibly different types of non-inferential justification, and that accounting for the existence of a specific sort of non-inferential justification is crucial for any adequate ethical intuitionist epistemology. In this context, it is the purpose of this paper to provide an account of non- inferentially justified belief which is superior to extant accounts, and, to give a refined statement of the core claim of ethical intuitionism which focuses on the type of non- inferential justification vital for a plausible intuitionist epistemology. Finally, it will be shown that the clarifications made in this paper make it far from obvious that two intuitionist accounts, which have received much recent attention, make good on intuitionism’s core claim.

We present the inconsistency-adaptive deontic logic DP r , a nonmonotonic logic for dealing with conflicts between normative statements. On the one hand, this logic does not lead to explosion in view of normative conflicts such as O A ∧ O ∼A, O A ∧ P ∼A or even O A ∧ ∼O A. On the other hand, DP r still verifies all intuitively reliable inferences valid in Standard Deontic Logic (SDL). DP r interprets a given premise set ‘as (...) normally as possible’ with respect to SDL. Whereas some SDL-rules are verified unconditionally by DP r , others are verified conditionally. The latter are applicable unless they rely on formulas that turn out to behave inconsistently in view of the premises. This dynamic process is mirrored by the proof theory of DP r. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Norms, Conventions, and PsychopathsNeil Levy (bio)Keywordspsychopathy, morality, conventions, responsibilityI am grateful to my commentators for their provocative challenges to my claim that psychopaths ought to be excused moral responsibility for their wrongdoing owing to their (alleged) failure to grasp the moral/conventional distinction. I have learned from all the commentators—now, and in some cases in the past as well—and I am sincerely honored by their having taken my work seriously (...) enough to comment on it, even if only to take issue with it. In what follows, I shall attempt to reply to their main criticisms. As will shortly become clear, I do not here have the space for anything like adequate responses. Instead, I shall have to content myself with programmatic statements of how such responses might go. Let me admit at the outset that until the details of these responses are fully worked out, and the relevant empirical research conduced, I cannot be sure that the responses will succeed. Nevertheless, there are grounds for confidence, given the available data.Because there is some overlap between the criticisms, I shall address some of them—those of Blair, Nichols, and Vargas—by topic rather than by commentator, before turning to Mullen and Matravers.Is the Ability to Understand the Moral/Conventional Distinction a Necessary Condition of Aptness for Moral Responsibility?Blair, as well as Vargas and Nichols, suggests that an agent's knowing that an action is against the rules might be sufficient to ground responsibility for performing that action, even if the agent lacks the ability to draw the moral/conventional distinction. As Blair points out, we do not reserve blame only for those who violate moral rules. Blame, and sometimes punishments, are also meted out to those who violate merely conventional norms. Because psychopaths can understand conventional norms perfectly well, they may therefore seem to be appropriate targets of at least some kind of moral blame.But is it really the case that agents are (ever) blameworthy for violating conventional norms alone? Many philosophers, for instance when considering the morality of civil disobedience, have argued that conventional norms are typically backed by second-order moral norms. Hence, for many or all conventional norms, there is a (defeasible) moral obligation not to violate that norm, an obligation independent of the content of the conventional norm; it is because there are such second-order moral obligations that agents are blameworthy for violating conventional norms. [End Page 163] But if this is the case, then the fact that we sometimes blame agents for violating conventional norms is not evidence against the claim that the ability to grasp moral norms is a necessary condition of blameworthiness. There is no reason to think that psychopaths will find it any easier to grasp second-order moral norms than first-order (of course, they may understand that there are such things as second-order norms—norms concerning norms—but for them such norms will only be conventional). In fact, it might be more difficult to understand the moral force of second-order moral norms than first, inasmuch as the harms caused by violating such norms are emotional and not physical. Normal subjects invest (some) conventional norms with moral significance, and it is for this reason that we regard violations of such norms as apt to give rise to blame; lacking the ability to draw the moral/conventional distinction, psychopaths cannot invest such norms with moral significance. Once again, for them these norms are merely conventional, and they therefore fail to grasp the full significance of violating them.It might be objected that if conventional transgressions are (sometimes) backed up by second-order moral norms, children would not classify them as neatly as they do. They would misclassify some conventional norms as moral, insofar as they are backed up by second-order moral norms. They would therefore deny that violations of conventions are permissible on the say-so of an authority. There are two possible explanations of children's classifications, compatible with the suggestion that some conventions are backed by second-order moral norms. First, it may be that greater cognitive sophistication is required to grasp second-order moral norms than... (shrink)

I explore various ways of integrating the framework for predeterminism, agency, and ability in[P.McNamara, Nordic J. Philos. Logic 5 (2)(2000) 135] with a framework for obligations. However,the agential obligation operator explored here is defined in terms of a non-agential yet personal obligation operator and a non-deontic (and non-normal) agency operator. This is contrary to the main current trend, which assumes statements of personal obligation always take agential complements. Instead, I take the basic form to be an agent’s being obligated (...) to be such that p. I sketch some logics for agential obligation based on personal obligation and agency, first in a fairly familiar context that rules out conflicting personal obligations (and derivatively, conflicting agential obligations), and then in contexts that do allow for conflicts (of both sorts).

Wittgenstein demystified the notion of 'observational self-knowledge'. He dislodged the long-standing conception that we have privileged access to our impressions, sensations and feelings through introspection, and more precisely eliminated knowing as the kind of awareness that normally characterizes our first-person present-tense psychological statements. He was not thereby questioning our awareness of our emotions or sensations, but debunking the notion that we come to that awareness via any epistemic route. This makes the spontaneous linguistic articulation of our sensations and impressions (...) nondescriptive. Not descriptions, but expressions that seem more akin to behaviour than to language. I suggest that Wittgenstein uncovered a new species of speech acts. Far from the prearranged consecration of words into performatives, utterances are deeds through their very spontaneity. This gives language a new aura: the aura of the reflex action. I argue, against Peter Hacker, that spontaneous utterances have the categorial status of deeds. This has no reductive consequences in that I do not suggest that one category is reduced to another, but that the boundary between them is porous. This explodes the myth of an explanatory gap between the traditionally distinct categories of saying (or thinking) and doing, or of mind and body. (shrink)

Chapter 1: An Introduction: The ‘Semantic Sting’ Argument Describes Dworkin’s theory as concerning the conditions of legal validity. “A legal system is a system of norms. Validity is a logical property of norms in a way akin to that in which truth is a logical property of propositions. A statement about the law is true if and only if the norm it purports to describe is a valid legal norm…It follows that there must be certain conditions which render certain norms, (...) but not others, legally valid. Hence it also follows that there can be two types of disagreement over the truth or falsehood of propositions about the law. People can disagree over the question ‘What are the conditions of legal validity?’, in which case their disagreement is a theoretical one. Or they can agree on the conditions of validity, and disagree as to whether or not those conditions actually obtain in a given case or not.” Argues that the best way to interpret Dworkin’s ‘semantic-sting argument’ is as a general argument against conventionalism in legal positivism. Summarizes the outcome of Dworkin’s argument as follows: “[I]f Dworkin is right about the legal reasoning of lawyers and judges, conventionalism would be self-defeating: if lawyers and judges recognize as legally binding not only those norms which are uncontroversially identifiable under the Rule of Recognition, that is, if what they recognize as binding is not only source-based law, then conventionalism turns out to be false on its own terms. In other words, either law is not what lawyers and judges think that it is, in which case law is not a matter of conventions, or – if it is what lawyers and judges think – conventionalism is false, as they do not see the law as purely a matter of conventions.” Dworkin’s theory, then, is a new conception of jurisprudence aiming to present itself as a rival to conventionalism. The book will be concerned with re-examining positivism in light of the interpretative challenge. Chapter 2: Meaning and Interpretation “[R]oughly, interpretation can be defined as an understanding or explanation of the meaning of an object.” Interpretation in this narrow sense is distinct from a less formal and broader use of interpretation that makes it equivalent to explanation. “Hence also, only those objects which are capable of bearing some meaning qualify as objects of interpretation.” [Why shouldn’t we think of interpretation as object-identification? This seems to be closer to what Dworkin has in mind.] Thus, a consideration of the philosophical work on meaning is appropriate. First, a consideration of Davidson on interpretation. The thesis is that Davidson’s “radical interpretation” can only account for sentence meaning and not for linguistic interpretation in general. Davidson cannot account for the non-rule-governed aspects of communication. “Semantics, as opposed to interpretation, concerns those aspects of communication which are rule or convention governed…but such rules are normally unavailable as reasons or justifications for an interpretation. On the contrary, interpretation is usually required because the issue is not determined by rules or conventions.” Interpretation, rather, is parasitic with understanding the meaning of an expression and not equivalent with it. As Dummett notes, any reflection on the meanings of words assumes prior knowledge of ordinary meanings. “This leads to the conclusion that understanding or explaining the meaning of an expression and interpreting it, are two conceptually separate things. It also indicates that seman ics can only be employed, if at all, to elucidate the concept of interpretation by way of contrast: interpretation concerns those aspects of communication which are under-determined by semantic rules or conventions.” Pragmatics, the study of problems posed by discrepancies between utterer’s meaning and sentence meaning, would seem to be closer to inquiry into interpretation. Both are concerned with understanding how meaning is possible where conventional rules leave off. Contemporary pragmatics, moreover, recognizes the logically indeterminate character of communicative inferences beyond conventional meaning and that the contextual conditions that account for the possibility cannot be realized in the semantic structure of the sentence. However, different criteria of success may be at work in pragmatics than interpretation. Pragmatics is concerned with how communication is achieved and thus the criteria of success would be grasping a speaker’s intentions. Many think, however, that communication is unimportant in certain spheres of communication, e.g. artistic interpretation, and that in these cases the aim of interpretation is not to uncover the actual artist’s intentions. What kind of meaning is interpretation aimed at then? It cannot be the meaning the object has for the interpreter. “Interpretation purports to be a statement about the object interpreted, not about the subject who offers the interpretation…it is crucial to remember that not everything we say about a work of art, or any other text, amounts to an interpretation of it. Only those aspects of a text which can shed light on its meaning form part of the text’s interpretation. What the text means for someone rarely entails anything about what the text means.” [This is puzzling to some extent for it remains somewhat ambiguous what it means to talk of subject-independent meaning.] Interpretive meaning attribution is, rather, counterfactual. “In general, I will suggest that the answer to this question consists in the fact that meaning is assigned by a counterfactual statement. Given that x is the meaning attributed to, for instance a text T, and x is not the literal meaning of T, nor is it the meaning of T intended by its author, then the attribution of meaning x to T can only be understood as the contention that on the basis of certain assumptions a certain fictitious or stipulated speaker would have meant x by expressing T.” Thus, on this account, interpretation, when it does not concern an actual speaker, turns out to be a kind of counterfactual intention attribution. Twofold point: “First, that interpretation is essentially a matter of attributing intentions, that is, in the pragmatics sense of ‘meaning’, namely, meaning that such-and-such by an act or expression. At the same time, interpretations need not be based on the intentions of actual authors; the meaning of an act or expression is understandable in terms of counterfactual intentions.” [Are we really restricted to understanding the coherence and integrity of meaning in such a way? Presumably the author is a kind of device for organizing meaning, much like Dworkin’s integrity, but need it take that format?] The logic of interpretation is typically reducible to intention attribution. [What role does the counterfactual author play in structuring meaning?] The criteria of interpretive success will depend upon the object, whether it is the real author or the counterfactual author. If the former, success will depend upon the retrieval of the author’s actual intentions. “Likewise, if the author is characterized in terms of some ideal representative of a certain genre, for instance, the presumptions which are taken to determine this c aracterization would provide the criteria of success for the particular interpretation offered.” [The criteria of success would seem, then, to be the principles, ideals, etc. that we attribute to the counterfactual author. These attributed qualities would be doing all the work – is the attribution of intention to the hypothetical author, then, really necessary at all?] [Does this account presuppose a weird dichotomy between what an object is and what it means? This dichotomy is different, if present at all, in Dworkin.] Chapter 3: Dworkin’s Theory of Interpretation and the Nature of Jurisprudence Three main insights of Dworkin’s theory of interpretation: “First, that interpretation strives to present its object in its best possible light. Second, that interpretation is essentially genre-dependent. And third, that there are certain constraints that determine the limits of possible interpretations of a given object.” Why the best light? Dworkin doesn’t really address this question in depth but claims that otherwise we are left with no way of justifying and choosing an interpretation or we are left with the author’s intention model, which we should reject. [Marmor doesn’t seem clear on what precisely it means to present something in its best light – seems to conflate it with most appealing light which, I take it, is different than what Dworkin has in mind.] “Dworkin is quite right to maintain that without having some views about the values inherent in the genre to which the text is taken to belong, no interpretation can take off the ground. The values we associate with the genre partly, but crucially, determine what would make sense to say about the text, what are the kinds of meaning we could ascribe to it.” There is no necessity for an interpretation to present an object in its best light with regards to the genre it is taken to be part of. Interpretations “could simply strive to present it in a certain light, perhaps better than some, worse than others, but in a way which highlights an aspect of the meaning of the text which may be worth paying attention to for some reason or another.” [What kind of reasons would count in choosing to present it in one light rather than another?] There is simply zero grounds for Dworkin’s assertion that we have no reason to pay attention to an interpretation that does not present it in its best light. Take a psychoanalytic interpretation of Hamlet, for example – not the best light, but a legitimate one. [This seems related to the next criticism – clearly Dworkin would have to loosen his insistence on the best, though not to detriment.] Moreover, especially with regards to art, it doesn’t appear possible to make an all things considered judgment about the best interpretation given the incommensurability of different values that are taken to inhere in a given genre. [Dworkin can respond here that we may have different available interpretations that could be justified with respect to the relevant value. Moreover, a lack of common denominator does not prevent any comparison whatsoever.] Constructive interpretation concerns social practices constituted by norms – it imposes a purpose or value rendering intelligible the normative character of the practice. There is a separate aspect of constructive interpretation that maintains that elements of the practice are sensitive to the point of the practice. It is important to note that different social practices will institutionalize themselves in different ways – thus, different practices will establish varying conditions on how the practice can be altered. The position of the positivists is that evaluative judgments concerning what the law should be are insufficient for determining what the law is given the nature of law’s institutionalization.&nb p; [This would seem to reside on a certain conception of law, i.e. an interpretation about where the value of law lies.] “[T]his being one of the main points of dispute between Dworkin and his positivist opponents, Dworkin cannot at this initial state presume law to be sensitive to its value in the manner that other, non-institutional practices might be, without incurring the charge of having assumed the very point at issue.” The upshot for Dworkin is that any explanation of a social practice such as law requires the same kind of reasoning as participation in that practice. This will be called the hermeneutic thesis. We can try to reconstruct a justification for this view based on the necessity of shared background assumptions – but this will not do since Dworkin’s claim is stronger: it contends that participants’ and theorists’ must “adopt one and the same normative point of view.” [The sense of normative here is unclear. It is true, though, that shared background assumptions do not imply viewing the law as valuable in any particular way, or at least it does not imply this in any strong sense.] Dworkin makes two distinct points with the hermeneutic thesis: “First, that the explanation of a social practice, like law or the arts, is essentially interpretative, and as such, necessarily value laden. Second, that the interpretation of such social practices, which Dworkin calls ‘argumentative’, is unique in the sense that the practice itself is an evaluative enterprise, and that therefore the interpreter of such a practice must form an evaluative judgment of her own about those values which are inherent in the practice that she purports to interpret.” [As stated, the first thesis is terribly ambiguous – for Dworkin, it clear implies a commitment to constructive interpretation. For Marmor, who accepts it, it is totally unclear what commitment he intends to make. He seems to mean simply that we have criteria for success concerning what counts as a successful explanation.] Mamor denies the second thesis. “What Dworkin seems to ignore here is that there is a crucial difference between forming a view about the values which are manifest in a social practice, like law, and actually having evaluative judgments about them.” [The problem, however, it that it is a contentious matter what values are part of the law – a theorist’s account of what values are constitutive of a particular legal system must rely on the kind of arguments which participants rely on. Of course, a theorist might simply note a debate about values and attempt to remain agnostic, but this will fail to be a full theoretical account of what law is!] Dworkin’s thesis seems to depend exclusively on his account of constructive interpretation. [This seems exactly right.] Chapter 4: Coherence, Holism, and Interpretation: The Epistemic Foundation of Dworkin’s Legal Theory Begins with discussion of Rawls’ reflective equilibrium. Sums up dual criticism as follows: “[T]he assumption that intuitions are independently true and the converse one, that their truth depends on fitting a coherent scheme, both seem to yield paradoxical results.” Dworkin, in his article “The Original Position”, claims that Rawls cannot commit himself to ethical realism. “[T]he natural model presupposes some form of ethical realism, while the constructive model does not. One important difficulty arising from an attempt to apply the natural model to Rawls is, that under the natural model, any theory which dopes not account for an intuition, at least for one which is held firmly, cannot be wholly satisfactory, just as scientific theory which does not account for certain observational data it is supposed to cover, would not be satisfactory in a familiar way.” Rawls, rather, is committed to a constructivist view of morality. Moreover, the reason we value coherence epistemically in moral theory is that it itself is a value of political morality – fairness requires consistency and publicity in the application of moral standards. Marmor notes the following problem with such a view: “[I]f coherence is justified, as it is here, with reference to certain moral values, that is, a specific conception of fairness, then we face the following problem: the presupposed values of fairness must themselves be based upon intuitive convictions, in which case the question of their truth cannot be ignored. If they are taken to be true…we are driven back to the perplexities of the natural model.” Discusses, helpfully, the Fish/Dworkin debate. The upshot is that Dworkin’s interpretive model is best off if it commits itself to a Quineian holism. However, this undermines his distinction between internal and external skepticism since holism must deny that moral judgments constitute a closed system. [This analysis seems exactly right.] Endorses Simmonds view that Dworkin’s theory does not meet the requirements of complexity he identifies as necessary to avoid vicious circularity in interpretive judgments of fit and identity. Coherence is doing the work through and through and therefore the interpretive theory of law is circular. [Will require further investigation, though it is unclear how coherence is doing any work in the pre-interpretive stage. At this stage, the judgments, if interpretive, seem to be derived from different sources. In any case, using coherence as a value seems to be highly suspect.] Why doesn’t Dworkin just reject Fish’s assumptions: because of his jurisprudence. “If legal texts can have a meaning that is not entirely dependent on a process of interpretation, then it is at least sometimes the case that the law can simply be understood, and applied, without the mediation of interpretation. And if that is the case, then the argument from interpretation against legal positivism collapses. It is no longer the case that every conclusion about what the law is, depends on evaluative considerations about what it ought to be.” Chapter 5: Semantics, Realism, and Natural Law Assessment of Michael Moore’s legal realism and its implications. [The final criticisms of Moore are not decisive.] Chapter 6: Constructive Identification and Razian Authority A consideration of Dworkin’s denial that the communication model of interpretation is appropriate for legal interpretation. Marmor argues that intentions do play a crucial role in the identification of legal norms in a way that is incompatible with Dworkin’s “coherence thesis”. Marmor takes Dworkin to be committed to the constructive identification thesis: that the identification of something as part of the legal, artistic, etc. genre can be done sufficiently by evaluative considerations. “Here, one must maintain that evaluative considerations are sufficient to determine whether something is a legal norm or a work of art”. [Fit, however, constrains possible evaluative considerations – thus evaluative considerations are not sufficient in themselves.] “Now the crucial point here is this: if you maintain the possibility of constructive identification in art, you must assume that works of art can be identified as such on the basis of certain features they happen to possess, features which contain no reference to any particular intention to create a work of art…unless we take intentions into account, how can we discriminate between the concept of an aesthetic artifact and the con ept of a work of art?” [It is unclear, and I think false, that constructive interpretation of anything requires identifying something irrespective of an artificers intentions. Those intentions may be relevant, dependent upon the genre under which we are trying to classify the object. Nothing, seemingly, about constructive interpretation in general excludes this possibility.] Marmor’s point is that it turns out to be impossible to identify art as art without reference to an artist’s intentions – especially given the state of contemporary art. [It is notable that Marmor’s response to counterexample implicitly depends upon a fully developed theory of aesthetics. His cursory comments on the matter of identifying art seem insufficient to say the least.] The rest of the chapter considers the incompatibility of Raz’s account of authority with constructive interpretation. The incompatibilities mentioned do not move beyond what Raz identifies in his article “Authority, Law and Morality”, but a defense of this notion of authority is defended in several [inconclusive] respects. [Raz and Marmor want to separate identification from content. This is not clearly a defensible separation.] Chapter 7: No Easy Cases? Chapter defends notion that there is a distinction between easy and hard cases in the positivist sense. Takes a Hartian approach and ultimately defends the distinction by associating it Wittgenstein’s conception of rule following. The point is that one need to look the purpose of rule in order to understand what the rule requires. Chapter 8: Legislative Intent and the Authority of Law Examines the following doctrine concerning the role of legislative intent in adjudication: “[F]irst, it would hold that laws, at least in certain cases, are enacted with relatively specific intentions, and that this is a matter of fact which is discernible through an ordinary fact-finding procedure. Second, that in certain cases the presence of such a fact, namely, that the law was enacted with a certain intention, provides judges with a reason to decide the legal dispute in accordance with the relevant legislative intent.” [It is important that for Marmor, interpretive strategies are only appropriate in hard cases. However, we should wonder what grounds positivism can offer for deciding a hard case in any manner which is not the morally best manner according to the judgment of the judge. There are no legal grounds, by definition, in hard cases and so what justificatory strategy would endorse any judicial decision except for the morally best one?] We can ascribe intentions to a legislative body, when this is possible at all, by taking the shared intentions of the majority, rather than some group intention, to be the significant intentions. Moreover, we should expect a good deal of consensus about intentions for otherwise it is hard to explain how legislative bodies are able to produce so much legislation. Discussion of kinds of intentions concludes as follows: “I have distinguished between three main types of intention that are potentially relevant from the legal point of view. Apart from the intentions that are manifest in the language of the law itself, legislators typically have further intentions in enacting a given law, and sometimes they would have certain intentions bearing on its proper application. I have also suggested that some of these further intentions may be essentially non-avowable, in which case they are rendered initially irrelevant. Finally, I have pointed out that considerations of consistency require that the legislator’s application intentions be taken into account only if, and to the extent that, they are in accord with his further intentions.” The manner in which intentionalism is to be justif ed relies on the distinction, Marmor maintains, between expert and mere collective action authority. “The point I wanted to make is strictly conditional: if, and only if, a certain law is justified on the basis of the expertise branch of the normal justification thesis, would it make sense to defer to the legislature’s intentions in the interpretation of the law, that is, to the extent that there is, in fact,; such an intention and it can clarify something that needs clarification.” Insofar as a legislature can be considered an expert on the matter requiring adjudication and interpretation should the body’s intention be taken into account. Chapter 9: Constitutional Interpretation Begins by laying out general necessary features of a constitution. Then Marmor moves on to consider general questions of constitutional legitimacy. First, he considers what grounds might be offered for the legitimacy of a constitution at all. He notes that the central question is what permits a single generation to bind future generations. He then examines four arguments to avoid this problem. The first is based on the moral legitimacy of the constitution; Marmor rejects this solution for the [truly dubious] reason that the constitution would make no practical difference because it would not supply reasons in addition to those provided by morality [but, presumably, the point is that these legally valid rules would be institutionally enshrined]. The second is based on the moral authority of the framers and Marmor rightly rejects this on the basis of the idealization of the framers it requires and less rightly on the basis that there cannot be moral authorities. Third is the “argument from interpretation” which claims that “as long as the particular content of the constitution is determined by its interpretation, and the authoritative interpretation at any time correctly instantiates the values which ought to be upheld in the community, the constitution would be morally legitimate”. The fourth is Raz’s which argues that a constitution is valid so long as its constraints are morally permissible because conventions of this type might aid the continuity of the legal system, i.e. it is important to have a convention of this type and the constitution is a kind of this type. Marmor appears to endorse these two approaches and concludes: “The conditions for the legitimacy of a constitution must comprise the following conditions. First, the values and principles enshrined in it must be morally permissible…Second, when certain choices are made in particular cases, they would be legitimate if they are either morally underdetermined, or else, morally correct…It follows from this that both arguments must assume that at least in those areas in which the constitution would make a moral difference, it can be interpreted to make the difference that it should, that is, according to the true moral principles that should apply to the particular case...the moral legitimacy of constitutions very much dependent on the practices of their interpretation. In other words, a great deal of the burden of moral legitimacy is shifted by these arguments to the application of the constitution, thus assuming that the constitution is legitimate only if the courts are likely to apply the constitution in a morally desirable way.” [This implies that the only significant value constitutions have is in providing a conventional practice where some such practice is required.] Moves on to argue that courts typically rely, and rightly so, on moral considerations when deciding constitutional issues because typically, in cases of the kind that reach the supreme or constitutional court, there is no law on the case. Much of this relies on his earlier discussion about the nature of interpretation in the law – that legal interpretation is always a matter of cha ging the law. (shrink)

\ is a 7000 line Prolog parser/theorem-prover for logical categorial grammar. In such logical categorial grammar syntax is universal and grammar is reduced to logic: an expression is grammatical if and only if an associated logical statement is a theorem of a fixed calculus. Since the syntactic component is invariant, being the logic of the calculus, logical categorial grammar is purely lexicalist and a particular language model is defined by just a lexical dictionary. The foundational logic of continuity was established (...) by Lambek while a corresponding extension including also logic of discontinuity was established by Morrill and Valentín :167–192, 2010). \ implements a logic including as primitive connectives the continuous and discontinuous connectives of the displacement calculus, additives, 1st order quantifiers, normal modalities, bracket modalities, and universal and existential subexponentials. In this paper we review the rules of inference for these primitive connectives and their linguistic applications, and we survey the principles of Andreoli’s focusing, and of a generalisation of van Benthem’s count-invariance, on the basis of which \ is implemented.

Although Strawson’s main aim in “On Referring” was to argue that definite descriptions can be used referentially – that is, “to mention or refer to some individual person or single object . . . , in the course of doing what we should normally describe as making a statement about that person [or] object” (1950, p. 320) – he denied that definite descriptions are always used referentially. The description in ‘Napoleon was the greatest French soldier’ is not used referentially, says (...) Strawson, since it is used not to mention an individual, but only “to say something about an individual already mentioned” (p. 320). This is an example of what we may call a predicative use of a definite description, though such uses might be better illustrated by considering the false sentence.. (shrink)

Some propositions are structurally unknowable for certain agents. Let me call them ‘Moorean propositions’. The structural unknowability of Moorean propositions is normally taken to pave the way towards proving a familiar paradox from epistemic logic—the so-called ‘Knowability Paradox’, or ‘Fitch’s Paradox’—which purports to show that if all truths are knowable, then all truths are in fact known. The present paper explores how to translate Moorean statements into a probabilistic language. A successful translation should enable us to derive a version (...) of Fitch’s Paradox in a probabilistic setting. I offer a suitable schematic form for probabilistic Moorean propositions, as well as a concomitant proof of a probabilistic Knowability Paradox. Moreover, I argue that traditional candidates to play the role of probabilistic Moorean propositions will not do. In particular, we can show that violations of the so-called ‘Reflection Principle’ in probability need not yield structurally unknowable propositions. Among other things, this should lead us to question whether violating the Reflection Principle actually amounts to a clear case of epistemic irrationality, as it is often assumed. This result challenges the importance of the principle as a tool to assess both synchronic and diachronic rationality—a topic which is largely independent of Fitch’s Paradox—from a somewhat unexpected source.

The renewed interest in the foundations of quantum statistical mechanics in recent years has led us to study John von Neumann’s 1929 article on the quantum ergodic theorem. We have found this almost forgotten article, which until now has been available only in German, to be a treasure chest, and to be much misunderstood. In it, von Neumann studied the long-time behavior of macroscopic quantum systems. While one of the two theorems announced in his title, the one he calls the (...) “quantum H-theorem,” is actually a much weaker statement than Boltzmann’s classical H-theorem, the other theorem, which he calls the “quantum ergodic theorem,” is a beautiful and very non-trivial result. It expresses a fact we call “normal typicality” and can be summarized as follows: For a “typical” finite family of commuting macroscopic observables, every initial wave function ψ0 from a micro-canonical energy shell so evolves that for most times t in the long run, the joint probability distribution of these observables obtained from ψt is close to their micro-canonical distribution.

Any attempt to construct a realist interpretation of quantum theory founders on the Kochen-Specker theorem, which asserts the impossibility of assigning values to quantum quantities in a way that preserves functional relations between them. We construct a new type of valuation which is defined on all operators, and which respects an appropriate version of the functional composition principle. The truth-values assigned to propositions are (i) contextual; and (ii) multi-valued, where the space of contexts and the multi-valued logic for each context (...) come naturally from the topos theory of presheaves. The first step in our theory is to demonstrate that the Kochen-Specker theorem is equivalent to the statement that a certain presheaf defined on the category of self-adjoint operators has no global elements. We then show how the use of ideas drawn from the theory of presheaves leads to the definition of a generalised valuation in quantum theory whose values are sieves of operators. In particular, we show how each quantum state leads to such a generalised valuation. A key ingredient throughout is the idea that, in a situation where no normal truth-value can be given to a proposition asserting that the value of a physical quantity A lies in a set D of real numbers , it is nevertheless possible to ascribe a partial truth-value which is determined by the set of all coarse-grained propositions that assert that some function f(A) lies in f(D), and that are true in a normal sense. The set of all such coarse-grainings forms a sieve on the category of self-adjoint operators, and is hence fundamentally related to the theory of presheave. (shrink)

The maximum entropy principle is widely used to determine non-committal probabilities on a finite domain, subject to a set of constraints, but its application to continuous domains is notoriously problematic. This paper concerns an intermediate case, where the domain is a first-order predicate language. Two strategies have been put forward for applying the maximum entropy principle on such a domain: applying it to finite sublanguages and taking the pointwise limit of the resulting probabilities as the size n of the sublanguage (...) increases; selecting a probability function on the language as a whole whose entropy on finite sublanguages of size n is not dominated by that of any other probability function for sufficiently large n. The entropy-limit conjecture says that, where these two approaches yield determinate probabilities, the two methods yield the same probabilities. If this conjecture is found to be true, it would provide a boost to the project of seeking a single canonical inductive logic—a project which faltered when Carnap's attempts in this direction succeeded only in determining a continuum of inductive methods. The truth of the conjecture would also boost the project of providing a canonical characterisation of normal or default models of first-order theories. Hitherto, the entropy-limit conjecture has been verified for languages which contain only unary predicate symbols and also for the case in which the constraints can be captured by a categorical statement of quantifier complexity. This paper shows that the entropy-limit conjecture also holds for categorical statements of complexity, for various non-categorical constraints, and in certain other general situations. (shrink)

Art viewers and critics talk as if visual artworks say things, express messages, or have meanings. For instance, Picasso’s 'Guernica' has been described as a “generic plea against the barbarity and terror of war”, forming a “powerful anti-war statement”. One way of understanding meaning in art is to draw analogies with language. My thesis explores how the notion of a speech act – an utterance with a performative aspect – can illuminate art’s power to ‘speak’. In recent years, philosophers of (...) art have explored speech act theory in relation to literary art, though barely at all in relation to visual art. Given the way we talk about painting, sculpture, installation, film, and photography, and given that artists have investigated performativity through their art, this neglect is surprising. My thesis develops two main arguments. First, artwork meaning is active. I argue that visual artworks, under certain conditions, are speech acts. They have propositional content, and they have a certain force: they can do things such as assert, protest, and criticise – things we would normally do with words. I defend these contested claims against several dissenters, and explore some consequences: in particular, I explore how art can lie, a hitherto neglected question. Second, artwork meaning is flexible. I argue that what an artwork says and does is affected by the context in which it’s displayed, and in particular, by its curation. As a result, an artwork’s content and force can vary from context to context. This goes against a dominant view in the philosophy of art – what I call ‘Originalism’ – that the meaning of an artwork is fixed by factors which held at the time of the work’s creation, and so cannot change across time. I argue that this is mistaken: artworks can change in meaning. Curatorial factors can affect an artwork’s content and force, and consequently its social effects. It is known that our verbal speech has the power to oppress and liberate people in a society. My thesis aims to show that art also has this power to shape society; through what it says, and through what it does. (shrink)
