In this book, Rupert Read offers the first outline of a resolute reading, following the highly influential New Wittgenstein 'school', of the Philosophical Investigations. He argues that the key to understanding Wittgenstein's later philosophy is to understand its liberatory purport. Read contends that a resolute reading coincides in its fundaments with what, building on ideas in the later Gordon Baker, he calls a liberatory reading. Liberatory philosophy is philosophy that can liberate the user from compulsive patterns of (...) thought, freeing one for possibilities that were previously obscured. Such liberation is our prime goal in philosophy. This book consists in a sequential reading, along these lines, of what Read considers the most important and controversial passages in the Philosophical Investigations 1, 16, 43, 95 & 116 & 122, 130-3, 149-151, 186, 198-201, 217, and 284-6. Read claims that this liberatory conception is simultaneously an ethical conception. The PI should be considered a work of ethics in that its central concern becomes our relation with others. Wittgensteinian liberations challenge widespread assumptions about how we allegedly are independent of and separate from others. Wittgenstein's Liberatory Philosophy will be of interest to scholars and advanced students working on Wittgenstein, and to scholars of the political philosophy of liberation and the ethics of relation.

In an article published thirteen years ago, I tried to break new ground by showing that the texts transmitted under the titleCataleptonas the work of Virgil can be seen to form an elaborately arranged and highly allusive book of verse written by a single author. This latter, I argued, was identical with the anonymous poet who, in an epilogue, represents the preceding poems as the juvenilia of the author later known for hisBucolics,GeorgicsandAeneidand, consequently, is himself speaking in the alleged early (...) works asVirgil impersonator. This anonymous poet, however, cannot rightly be labelled a literary forger, since he repeatedly and quite unmistakably recalls each of Virgil's threeoperaas well as other texts written after the year 19b.c. Evidently, then, he is inviting his readers to take part in a literarylusus, one in which they are expected to be familiar not only with the texts ofBucolics,GeorgicsandAeneidbut also with the life of the man who wrote them. The fiction of a young Virgil is created, one who wrote his first poems—the verses referred to in the epilogue aselementaandrudis Calliope—primarily under the influence of Catullus, the said poems being, with the exception ofCatal.12 and 16, epigrams. My interpretation has borne fruit, with Irene Peirano and Markus Stachon each devoting, in 2012 and 2014 respectively, a monograph to this approach and offering what are often very thorough analytical readings of the poems as the creations of aVirgil impersonator. However, neither of these two Latinists has considered one particular interpretative aspect, which I myself had only been able to introduce very briefly into my paper: the recognition that, as many more recent studies have now further corroborated, Roman poetry books were designed for linear, sequential reading, that they have, as it were, a story to tell. Peirano, moreover, disregards in her study the threePriapeapositioned in editions before the other fifteen epigrams and shown there with their own separate numbering. In the manuscripts, however, the titleCataleptonrefers without exception to a unit comprising the threePriapeaand the fifteen epigrams. The titlePriapea, found in the catalogue of the Murbach manuscripts and in some codices, is always attached solely to the poemQuid hoc noui est?In theVita Suetoniana-Donatiana, the termsCatalepton,PriapeaandEpigrammatawere evidently used as three different titles; the author may not have seen thatCataleptonis the title of all the poems. Furthermore, I should like to point out that, counted together, ‘Virgil's’Priapeaand epigrams come to a total of seventeen poems and so match precisely both the total of seventeen books in the real Virgil's three works and the total number of Horace's epodes, of the poems, that is, which the not-so-real Virgil quite conspicuously evokes in his own penultimate poem. More significantly, however, a sequential reading of thePriapea et Epigrammatacan in fact build a watertight case for taking the texts to be, as it were, a composite whole, and that is what I intend to argue in the rest of the article.

One of the unconventional features of Wittgenstein’s _Tractatus Logico-Philosophicus_ is its use of an elaborated and detailed numbering system. Recently, Bazzocchi, Hacker und Kuusela have argued that the numbering system means that the _Tractatus_ must be read and interpreted not as a sequentially ordered book, but as a text with a two-dimensional, tree-like structure. Apart from being able to explain how the _Tractatus_ was composed, the tree reading allegedly solves exegetical issues both on the local and the global level. (...) This paper defends the sequential reading against the tree reading. After presenting the challenges generated by the numbering system and the two accounts as attempts to solve them, it is argued that Wittgenstein’s own explanation of the numbering system, anaphoric references within the _Tractatus_ and the exegetical issues mentioned above do not favour the tree reading, but a version of the sequential reading. This reading maintains that the remarks of the _Tractatus_ form a sequential chain: The role of the numbers is to indicate how remarks on different levels are interconnected to form a concise, surveyable and unified whole.

Humans can pronounce a nonword. Some researchers have interpreted this behavior as requiring a sequential mechanism by which a grapheme-phoneme correspondence rule is applied to each grapheme in turn. However, several parallel-distributed processing models in English have simulated human nonword reading accuracy without a sequential mechanism. Interestingly, the Japanese psycholinguistic literature went partly in the same direction, but it has since concluded that a sequential parsing mechanism is required to reproduce human nonword reading accuracy. In (...) this study, by manipulating the list composition, we demonstrated that past psycholinguistic studies in Japanese have overestimated human nonword reading accuracy. When the more fairly reevaluated human performance was targeted, a newly implemented Japanese PDP model simulated the target accuracy as well as the error patterns. These findings suggest that PDP models are a more parsimonious way of explaining reading across various languages. (shrink)

The paper analyses the impact of the discovery of the division of infusoria on eighteenth century microscopical iconography. In Autumn 1765, when reproducing the antispontaneist experiments of Lazzaro Spallanzani, Horace-Bénédict de Saussure (1740-1799) discovered a new method of generation of the animalcules of the infusions, namely their division. Drawing a dividing animalcule raised particular problems, notably the question of how to depict the time sequence of a microscopical creature. Although Saussure's journal of microscopical experiments remained unpublished, the discovery was soon (...) diffused and acknowledged by the European naturalists who began to repeat the observations and quickly faced iconographic problems similar to those experienced by Saussure. Indeed, linearity, used to picture time, is a construction, and, notably for public images, scholars had to contend with the conventions of drawers and engravers. The analysis of microscopical iconographic material of the period 1740-1786 shows that during this period, certain naturalists invented new solutions for depicting time, but diffusion of their innovations was not immediate. Nevertheless, in regards to the illustration of microscopical creatures, it is between 1765 and 1776 that the use of linearity was established as a solution enabling an audience to read an iconographic time process as a text.

More than 50 years after it was first published, The Concept of Law remains the most important work of legal philosophy in the English-speaking world. In this volume, written for both students and specialists, 13 leading scholars look afresh at Hart's great book. Unique in format, the volume proceeds sequentially through all the main ideas in The Concept of Law: each contributor addresses a single chapter of Hart's book, critically discussing its arguments in light of subsequent developments in the field. (...) Four concluding essays assess the continued relevance for jurisprudence of the 'persistent questions' identified by Hart at the beginning of The Concept of Law. The collection also includes Hart's 'Answers to Eight Questions', written in 1988 and never before published in English. Contributors include Timothy Endicott, Richard HS Tur, Pavlos Eleftheriadis, John Gardner, Grant Lamond, Nicos Stavropoulos, Leslie Green, John Tasioulas, Jeremy Waldron, John Finnis, Frederick Schauer, Pierluigi Chiassoni and Nicola Lacey.

The results of a hypothetical experiment requiring a sequence of quantum measurements are obtained retrospectively, after the experiment has been completed, from a single reading of an “apparatus register.” The experiment is carried out reversibly and Schrödinger's equation is satisfied until the terminal reading of the register. The technique is illustrated using a feasible method of measuring photon spin as the quantum “object” observable and using the photon energy as the “apparatus register.” The technique is used to discuss (...) the “watchdog” effect, the effect of repeated measurements inhibiting quantum jumps.

This study investigated visual statistical learning (VSL) in 24 deaf signers and 24 hearing non‐signers. Previous research with hearing individuals suggests that SL mechanisms support literacy. Our first goal was to assess whether VSL was associated with reading ability in deaf individuals, and whether this relation was sustained by a link between VSL and sign language skill. Our second goal was to test the Auditory Scaffolding Hypothesis, which makes the prediction that deaf people should be impaired in sequential (...) processing tasks. For the VSL task, we adopted a modified version of the triplet learning paradigm, with stimuli presented sequentially across space and time. Results revealed that measures of sign language skill (sentence comprehension/repetition) did not correlate with VSL scores, possibly due to the sequential nature of our VSL task. Reading comprehension scores (PIAT‐R) were a significant predictor of VSL accuracy in hearing but not deaf people. This finding might be due to the sequential nature of the VSL task and to a less salient role of the sequential orthography‐to‐phonology mapping in deaf readers compared to hearing readers. The two groups did not differ in VSL scores. However, when reading ability was taken into account, VSL scores were higher for the deaf group than the hearing group. Overall, this evidence is inconsistent with the Auditory Scaffolding Hypothesis, suggesting that humans can develop efficient sequencing abilities even in the absence of sound. (shrink)

The article re-examines the relationship between the works of Alfred Schütz and Harold Garfinkel, focusing on their respective approaches to temporality in interaction. Although there are good reasons to emphasize the differences between Schütz’s notion of individual projects of action and Garfinkel’s interest in communicative sequencing, there is also an interesting historical connection. In order to elucidate this connection, the article provides a close reading of the steps that lead Schütz from his premise of ‘egological’ time consciousness to his (...) understanding of the reflexive and interactive process of meaning establishment and interpretation developed in his first book, _The Phenomenology of the Social World_ (1967 [1932]). The article reflects further upon which aspects of Schütz’s considerations resonated with Garfinkel in his formative years and how Garfinkel related to them variously in his later development of ethnomethodology. Hence, it appears that Garfinkel’s ethnomethodology successively departs from many of Schütz’s premises while simultaneously incorporating and further developing some of his notions on the sequential organization and temporal flux of interactive processes.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Reading After Actium: Vergil's Georgics, Octavian, and RomeSergio CasaliChristopher Nappa. Reading After Actium: Vergil's Georgics, Octavian, and Rome. Ann Arbor: University of Michigan Press, 2005. xii + 293 pp. Cloth, $75.Nappa's reading of the Georgics is a linear one: in his own words, his book is "a literary commentary that moves sequentially through the text from beginning to end" (3). After the introduction, the book (...) is divided into four chapters, each one devoted to a single book of the poem. This is how Nappa presents his work: "It is my contention that the Georgics can be profitably understood as a post-Actium 'reading,' or rather a set of them, of the situation in which Octavian found himself in the early 20s b.c.e., after the battle of Actium and before the assumption of the title Augustus. Perhaps more importantly, the Georgics represents an attempt to engage in a constructive dialogue with Octavian on the potential courses available to him and on the potential interpretations of his character, achievements, and motives, which would have been a central concern to the Roman and Italian elite"; Nappa wants to read the Georgics "as a didactic work addressed to Octavian, one that invites him (and any other reader) to react to specific problems, puzzles, and challenges" (1–3).From these proemial declarations I was expecting a linear reading of the poem constantly focused on Octavian as the model reader of the text, a consistent attempt to imagine his reactions as the "disciple" of Vergil. In fact, Nappa does not do that, at least not in a fully consistent way. Octavian as the ideal disciple and the poem as a series of "lessons" to the princeps are only a part of Nappa's actual reading of Vergil's text. I must confess that this discovery has been a bit disappointing, especially since the first chapter does in fact rather brilliantly begin with a lesson to Augustus; but this is due to the fact that the poem, of course, opens with an invocation to the princeps. Unfortunately, after that Octavian will not always be the center of attention, as I was hoping. But this does not mean that Nappa does not have interesting things to say about Vergil's poem.The introduction (1–22) clarifies Nappa's avowedly reader-oriented approach to Vergil's text: he proposes to confront the poem's difficulties and contradictions as, in a sense, the real meaning of the text: "the lessons of the [End Page 611] Georgics do not consist of the transmission of information but of the experience of confronting the often chimerical world presented by the poet.... the Georgics emphasizes the fact that in our quest for a meaning various audiences will construct (or discover) different, and even mutually exclusive meanings" (3). After a defense of intentionality as a heuristic tool for reading the Georgics, Nappa discusses the complex status of Octavian in the poem. First of all, he is the poem's addressee, "the most important audience Vergil has ever had," to whom to poet address even harsh lessons ("Octavian must understand the nature of the world he is trying to govern and the way the world sees him," 6); but he is also one of the topics of discussion, and at the same time one of the gods who are asked to favor the poet's undertaking. For Nappa, "the poem does not express a view of the princeps or his achievements so much as it invites the audience, Octavian as well as us, to consider the theme from multiple points of view" (8). Vergil's famous "mistakes" also "serve a didactic purpose: by inviting his readers to consider agricultural advice that is either obviously erroneous or presented in a highly selective and nonsequential way, the teaching poet compels them to search for deeper meaning, a term I use with some reluctance. The meaning each reader finds will, of course, depend on that reader" (11). In the last section of the introduction, Nappa locates the position of his reading within recent scholarship on the Georgics: his aporetic stance recalls above all Christine Perkell, The Poet's Truth (Berkeley...

ABSTRACTIn the first section I ask two questions: what sort of a poem is Childe Harold’s Pilgrimage, and what is the immediate experience of reading it in sequence? These two questions are the practical equivalents of the main terms of my title. I try to answer them by reconstructing a first reading of the poem in the light of my own experience and the imagined one of the first readers of the poem. I suggest that two terms—accretion and (...) elimination—are helpful here and that, in some ways, the structure and sequential experiencing of the poem resemble the structures of extended nineteenth-century musical forms. In the second section, I reverse perspective and take a position at the end of the poem. From such a point, it is easier to find what the poem has included and eliminated and this, in turn, suggests the kind of poem that it is. In the third section I tackle the terms “improvisation” and “hybrid genres” directly, link them with my earlier arguments, and engage with some theorists, especially Bakhtin.... (shrink)

Reichle et al. specify two assumptions as being basic to E-Z Reader: Words are sequentially attended during fixations, and saccades are triggered by a cognitive event. We point out that there is little evidence for the first assumption and counterevidence for the second. Also, the labile/nonlabile stage distinction in saccade preparation seems to be contrary to current evidence. An alternative explanation of saccade onset times in reading assumes that saccades are strategically generated, independent of language processing, but are delayed (...) on a probabilistic basis by processing difficulties.

Thom Brooks'sHegel's Political Philosophy: A Systematic Reading of the Philosophy of Rightpresents a very clear and methodologically self-conscious series of discussions of key topics within Hegel's classic text. As one might expect for a ‘systematic’ reading, the main body of Brooks's text commences with an opening chapter on Hegel's system. Then follow seven chapters, the topics of which are encountered sequentially as one reads through thePhilosophy of Right. Brooks's central claim is that too often Hegel's theories or views (...) on any of these topics are misunderstood because of a tendency to isolate the relevant passages from the encompassing structure of thePhilosophy of Rightitself, and, in turn, from Hegel's system of philosophy as a whole, with its logical underpinnings. Brooks is clearly right in holding that Hegel hadintendedthePhilosophy of Rightto be read against the background of ‘the system’ and the ‘logic’ articulating it —nobody doubts that— but there is a further substantive issue here.Shouldcontemporary readers heed Hegel's advice? Brooks's answer is emphatically in the affirmative, and what results is a series of illuminating discussions in which he makes a case for his own interpretations on the basis of systematic considerations, presented against a range of alternatives taken from the contemporary secondary literature, which is amply covered, often in the extensive endnotes to the book.

Recently, dynamic text presentation, such as scrolling text, has been widely used. Texts are often presented at constant timing and speed in conventional dynamic text presentation. However, dynamic text presentation enables visually presented texts to indicate timing information, such as prosody, and the texts might influence the impression of reading. In this paper, we examined this possibility by focusing on the temporal features of digital text in which texts are represented sequentially and with varying speed, duration, and timing. We (...) call this “textual prosody.” We used three types of textual prosody: “Recorded,” “Shuffled,” and “Constant.” Recorded prosody is the reproduction of a reader’s reading with pauses and varying speed that simulates talking. Shuffled prosody randomly shuffles the time course of speed and pauses in the recorded type. Constant prosody has a constant presentation speed and provides no timing information. Experiment 1 examined the effect of textual prosody on people with normal hearing. Participants read dynamic text with textual prosody silently and rated their impressions of texts. The results showed that readers with normal hearing preferred recorded textual prosody and constant prosody at the optimum speed. Recorded prosody was also preferred at a low presentation speed. Experiment 2 examined the characteristics of textual prosody using an articulatory suppression paradigm. The results showed that some textual prosody was stored in the articulatory loop despite it being presented visually. In Experiment 3, we examined the effect of textual prosody with readers with hearing loss. The results demonstrated that readers with hearing loss had positive impressions at relatively low presentation speeds when the recorded prosody was presented. The results of this study indicate that the temporal structure is processed regardless of whether the input is visual or auditory. Moreover, these results suggest that textual prosody can enrich reading not only in people with normal hearing but also in those with hearing loss, regardless of acoustic experiences. (shrink)

In this study, we investigated how word- and text-level processes contribute to different types of reading fluency measures. We aimed to increase our understanding of the underlying processes necessary for fluent reading. The sample included 73 Dutch Grade 3 children, who were assessed on serial word reading rate, word-list reading fluency, and sentence reading fluency. Word-level processes were individual word recognition speed and sequential processing efficiency. Text-level processes were receptive vocabulary and syntactic skills. The (...) results showed that word- and text-level processes combined accounted for a comparable amount of variance in all fluency outcomes. Both word-level processes were moderate predictors of all fluency outcomes. However, vocabulary only moderately predicted sentence reading fluency, and syntactic skills merely contributed to sentence reading fluency indirectly through vocabulary. The findings indicate that sequential processing efficiency has a crucial role in reading fluency across various measures besides individual word recognition speed. Additionally, text-level processes come into play when complexity and context availability of fluency measures increases, but the exact timing requires further study. Findings are discussed in terms of future directions and their possible value for diagnostic assessment and intervention of reading difficulties. (shrink)

Disney represents a mythology that is universal because they are rapidly acquiring every possible alternate reality that one cares to enter, except for the sexual realm and the Christian religion realm. When Disney owns all possible significant alternate universes, then only Disney can colonize one's imagination, and only Disney will give him/her the lens through which to perceive any competing claim on understanding his/her ultimate Reality. Well, visual containment helps the psyche stay in the mode and the mood for the (...) various psychic propaganda programs being run, and allows one to enjoy and prolong the fantasy, as well as empty his/her wallet of all possible contents since the only way to experience more Disney is to hand them exactly all of his/her cash. Thus, in short order, Disney has successfully colonized an awful lot of the global imagination, from young to old, male to female, from history to fantasy, and now from right to left. (shrink)

Paul of Venice joined the Austin Friars at an early age and was sent by them from Padua to study at Oxford in 1390. When he returned, full of ideas and laden with books, he began his prodigious writing career with several books on logic, including the Logica Magna, which runs to some half a million words. The current volume contains the final treatise, on insolubles - that is, logical paradoxes. After surveying fifteen previous solutions, Paul develops his own, based (...) on the idea that such propositions falsify themselves. Besides a critical edition of the Latin text, the volume also contains an English translation, a detailed commentary, excerpts from two other logical works of Paul, and a substantial introduction. The introduction describes the fourteenth-century background to Paul's treatise; it also gives a detailed rebuttal of a recent claim that the Logica Magna is not by Paul because its content clashes with genuine works of his. All in all, the volume greatly enhances our understanding of the development of logic, in particular of the semantics of propositions, during a crucial century in its history. (shrink)

This print edition of Read's account of logical thought includes the original publication's diagrams and tables. In this excellent book, Read commences by offering an overview of past attitudes and definitions of logic. Individual chapters consider the various means by which logical processes are conceived and developed in the mind. Philosophical arguments, spatial reasoning and mathematical forms of logic are discussed in great depth, with illustrations appended where deemed necessary. Read, an academic and philosopher, employs his decades long experience of (...) teaching students about the logical disciplines to write a detailed and comprehensive accounts of logic's aspects. Throughout this work, he attempts to retain a clarity of expression which makes the concepts discussed understandable for readers previously unversed in the types of logical expression. Read also sets out the principles behind setting up a hypothesis, and highlights the common logical fallacies which crop up in human reasoning. Extensive attention is given to the process of syllogism, by which sound conclusions are drawn from the premises offered. Throughout the book, Read is attentive in defining and explaining the esoteric terminology native to logic. As well as allowing the reader swift comprehension of the various subtopics, this explanatory style confers improved flow to the book. At the conclusion we are offered many questions corresponding to each chapter: these are intended to test the reader's understanding, and enforce the mental habits of utilising logical and critical thought. First published in 1898 and subject to several editions with revisions and refinements thereafter, Logic Deductive and Inductive retains a good reputation among academics and logicians. Its successful balance between striking a concise introductory tone with an embrace of the core elements of the subject has served to preserve its popularity into the modern day. (shrink)

"The Politics of Transindividuality" proposes a new understanding of not just the relation of the individual to the collective, but of politics and economics, one that can not only keep pace with existing transformations of capital but ultimately contest them.

A central component in the E-Z Reader model is a two-stage word processing mechanism made responsible for both the triggering of eye movements and sequential shifts of attention. We point to problems with both the verbal description of this mechanism and its computational implementation in the simulation. As an alternative, we consider the use of a connectionist processing module in combination with a more indirect form of cognitive eye-movement control.

The logician's central concern is with the validity of argument. A logical theory ought, therefore, to provide a general criterion of validity. This book sets out to find such a criterion, and to describe the philosophical basis and the formal theory of a logic in which the premises of a valid argument are relevant to its conclusion. The notion of relevance required for this theory is obtained by an analysis of the grounds for asserting a formula in a proof.

There exists a common view that for theories related by a ‘duality’, dual models typically may be taken ab initio to represent the same physical state of affairs, i.e. to correspond to the same possible world. We question this view, by drawing a parallel with the distinction between ‘interpretational’ and ‘motivational’ approaches to symmetries.

In this book, Stephen Read sets out to rescue logic from its undeserved reputation as an inflexible, dogmatic discipline by demonstrating that its technicalities and processes are founded on assumptions which are themselves amenable to philosophical investigation. He examines the fundamental principles of consequence, logical truth and correct inference within the context of logic, and shows that the principles by which we delineate consequences are themselves not guaranteed free from error. Central to the notion of truth is the beguiling issue (...) of paradox. Its philosophical value, Read shows, lies in exposing the invalid assumption on which the paradox is built. Thinking About Logic also discusses logical puzzles which introduce questions relating to language, the world, and their relationship. (shrink)

Inferentialism claims that expressions are meaningful by virtue of rules governing their use. In particular, logical expressions are autonomous if given meaning by their introduction-rules, rules specifying the grounds for assertion of propositions containing them. If the elimination-rules do no more, and no less, than is justified by the introduction-rules, the rules satisfy what Prawitz, following Lorenzen, called an inversion principle. This connection between rules leads to a general form of elimination-rule, and when the rules have this form, they may (...) be said to exhibit “general-elimination” harmony. Ge-harmony ensures that the meaning of a logical expression is clearly visible in its I-rule, and that the I- and E-rules are coherent, in encapsulating the same meaning. However, it does not ensure that the resulting logical system is normalizable, nor that it satisfies the conservative extension property, nor that it is consistent. Thus harmony should not be identified with any of these notions. (shrink)

We approach the physics of \emph{minimal coupling} in general relativity, demonstrating that in certain circumstances this leads to violations of the \emph{strong equivalence principle}, which states that, in general relativity, the dynamical laws of special relativity can be recovered at a point. We then assess the consequences of this result for the \emph{dynamical perspective on relativity}, finding that potential difficulties presented by such apparent violations of the strong equivalence principle can be overcome. Next, we draw upon our discussion of the (...) dynamical perspective in order to make explicit two `miracles' in the foundations of relativity theory. We close by arguing that the above results afford us insights into the nature of special relativity, and its relation to general relativity. (shrink)

Anti-exceptionalism about logic is the doctrine that logic does not require its own epistemology, for its methods are continuous with those of science. Although most recently urged by Williamson, the idea goes back at least to Lakatos, who wanted to adapt Popper's falsicationism and extend it not only to mathematics but to logic as well. But one needs to be careful here to distinguish the empirical from the a posteriori. Lakatos coined the term 'quasi-empirical' `for the counterinstances to putative mathematical (...) and logical theses. Mathematics and logic may both be a posteriori, but it does not follow that they are empirical. Indeed, as Williamson has demonstrated, what counts as empirical knowledge, and the role of experience in acquiring knowledge, are both unclear. Moreover, knowledge, even of necessary truths, is fallible. Nonetheless, logical consequence holds in virtue of the meaning of the logical terms, just as consequence in general holds in virtue of the meanings of the concepts involved; and so logic is both analytic and necessary. In this respect, it is exceptional. But its methodologyand its epistemology are the same as those of mathematics and science in being fallibilist, and counterexamples to seemingly analytic truths are as likely as those in any scientic endeavour. What is needed is a new account of the evidential basis of knowledge, one which is, perhaps surprisingly, found in Aristotle. (shrink)

Michael Dummett and Dag Prawitz have argued that a constructivist theory of meaning depends on explicating the meaning of logical constants in terms of the theory of valid inference, imposing a constraint of harmony on acceptable connectives. They argue further that classical logic, in particular, classical negation, breaks these constraints, so that classical negation, if a cogent notion at all, has a meaning going beyond what can be exhibited in its inferential use. I argue that Dummett gives a mistaken elaboration (...) of the notion of harmony, an idea stemming from a remark of Gerhard Gentzen's. The introduction-rules are autonomous if they are taken fully to specify the meaning of the logical constants, and the rules are harmonious if the elimination-rule draws its conclusion from just the grounds stated in the introduction-rule. The key to harmony in classical logic then lies in strengthening the theory of the conditional so that the positive logic contains the full classical theory of the conditional. This is achieved by allowing parametric formulae in the natural deduction proofs, a form of multiple-conclusion logic. (shrink)

Does the gravitational field described in general relativity possess genuine stress-energy? We answer this question in the affirmative, in a weak sense applicable in a certain class of frames of a certain class of models of the theory, and arguably also in a strong sense, applicable in all frames of all models of the theory. In addition, we argue that one can be a realist about gravitational stress-energy in general relativity even if one is a relationist about spacetime ontology. In (...) each case, our reasoning rests upon a functionalist approach to the definition of physical quantities. (shrink)
