In celebrating Arthur Prior we celebrate what he gave to the world. Much of this is measured by what others have made of his ideas after his death. The focus of this paper is a little different. It looks at what Prior himself thought he was accomplishing. In particular it considers Prior’s attitude to the semantic metatheory of the logics that he was interested in. The paper sets out some characteristics of the metalogical study of intensional languages in terms of (...) an indexical theory of truth conditions stated in the language of set theory. In examining Prior’s work using these characteristics, it emerges that Prior had serious reservations about this way of studying modal and tense logics. (shrink)

Our purpose in the present work is to survey some of the formulations that the theme of networks has received in contemporary philosophy of science over a period spanning twelve decades, from the end of the 19th century up to the present time. The proposal advanced herein is to interpret the evolution of this theme in four stages: first, one that goes from a metaphor or expressive image to a notion aspiring at implementation, but still having a virtual character, in (...) the orthodox view of theories; second, a shift towards networks viewed as explicit, with the notion still having an enormous metaphorical power, as in Neurath and Quine; third, from this towards a concept amenable to implementation, as in Thagard, but still in search of an epistemological rationale, supposedly provided by BonJour and Dancy; and finally, as a notion fully endowed with a precise structuralist implementation, in the scope of the structuralist metatheory of Balzer-Moulines-Sneed. The interpretive framework adopted in this exercise in the history of philosophy of science is a modified version of Gerald Holton's thematic model, adapted to the history of philosophy instead of its original domain, the history of scientific ideas. In our version of the thematic model, we posit two main dimensions for the appraisal of any given philosophical concept, besides the thematic dimension: the metaphorical one and the dimension of its systematic implementation.

In this essay I consider what is meant by the description ‘great’ philosophy and then offer some broadly applicable criteria by which to assess candidate thinkers or works. On the one hand are philosophers in whose case the epithet, even if contested, is not grossly misconceived or merely the product of doctrinal adherence on the part of those who apply it. On the other are those – however gifted, acute, or technically adroit – to whom its application is inappropriate because (...) their work cannot justifiably be held to rise to a level of creative-exploratory thought where the description would have any meaningful purchase. I develop this contrast with reference to Thomas Kuhn’s distinction between ‘revolutionary’ and ‘normal’ science, and also in light of J.L. Austin’s anecdotal remark – à propos Leibniz – that it was the mark of truly great thinkers to make great mistakes, or to risk falling into certain kinds of significant or consequential error. My essay goes on to put the case that great philosophy should be thought of as involving a constant readiness to venture and pursue speculative hypotheses beyond any limits typically imposed by a culture of ‘safe’, well-established, or academically sanctioned debate. At the same time – and just as crucially – it must be conceived as subject to the strictest, most demanding standards of formal assessment, i.e., with respect to basic requirements of logical rigour and conceptual precision. Focusing mainly on the work of Jacques Derrida and Alain Badiou I suggest that these criteria are more often met by philosophers in the broadly ‘continental’ rather than the mainstream ‘analytic’ line of descent. However – as should be clear – the very possibility of meeting them, and of their being jointly met by any one thinker, is itself sufficient indication that this is a false and pernicious dichotomy.

Sometimes we give truth-conditions for sentences of a discourse in other terms. According to Agustín Rayo, when doing so it is sometimes legitimate to use the terms of that very discourse, so long as the terms do not occur in the truth-conditions themselves. I argue that giving truth-conditions in this "outscoping" way prevents one from answering "discourse threat" (for example, the threat of indeterminacy).

The concept of a “scientific philosophy” first developed in the mid nineteenth century, as a reaction against what was viewed as the excessively speculative and metaphysical character of post-Kantian German idealism. One of the primary intellectual models of this movement was a celebrated address by Hermann von Helmholtz, “Über das Sehen des Menschen,” delivered at the dedication of a monument to Kant at Königsberg in 1855. Helmholtz begins by asking, on behalf of the audience, why a natural scientist like himself (...) is speaking in honor of a philosopher. This question only arises, he says, because of the current deplorable climate of enmity and mutual distrust between the two fields – a climate which is due, in Helmholtz’s opinion, to the entirely speculative system of Naturphilosophie that Schelling and Hegel have erected wholly independent of, and even in open hostility towards, the actual positive results of the natural sciences. What Helmholtz is now recommending, however, is a return to the close cooperation between the two fields exemplified in the work of Kant, who himself made significant contributions to natural science , and, in general, “stood in relation to the natural sciences together with the natural scientists on precisely the same fundamental principles.”1 And it was this recommendation that was enthusiastically embraced within the emerging “back to Kant!” movement, where it led to the idea that all metaphysics should be replaced by the new discipline of “epistemology” or “theory of knowledge” , so that philosophy itself would now become “scientific.”.

The relationship between Legal Realism and Legal Positivism has been a recurrent source of debate. The question has been further complicated by the related difficulty of assessing the internal relationship between the two main original strands of Legal Realism: American and Scandinavian. This paper suggests considering American and Scandinavian Realism as instantiations of forward-looking and backward-looking rule skepticism respectively. This distinction brings into sharp relief not only the fundamentally different relationship between each of these two Realist schools and Legal Positivism (...) but also their equally different potentials as starting points for naturalizing jurisprudence.

The meaning of a symbol is determined by its use, but the canonical way of specifying meaning is in a statement of the form "S means...". To be able to provide such a specification is equivalent to being able to translate the symbol S into one's own terms. A change in usage of terms involves a change of meaning iff the correct translation between earlier usage and later usage takes a term into a different expression. Such translation is holistic, a (...) matter of finding the best mapping. Sameness of meaning is a similarity relation, as is sameness of concept. The meaning of a larger expression is derived from the meaning of its parts iff the translation of the whole is derived from the translation of its parts. (shrink)

In this paper we argue that an existing theory of concepts called dynamic frame theory, although not developed with that purpose in mind, allows for the precise formulation of a number of problems associated with induction from a single instance. A key role is played by the distinction we introduce between complete and incomplete dynamic frames, for incomplete frames seem to be very elegant candidates for the format of the background knowledge used in induction from a single instance. Furthermore, we (...) show how dynamic frame theory provides the terminology to discuss the justification and the fallibility of incomplete frames. In the Appendix, we give a formal account of incomplete frames and the way these lead to induction from a single instance. (shrink)

This article offers a critical review of various ontological-relativist arguments, mostly deriving from the work of W. V. Quine and Thomas K hn. I maintain that these arguments are (1) internally contradictory, (2) incapable of accounting for our knowledge of the growth of scientific knowledge, and (3) shown up as fallacious from the standpoint of a causal-realist approach to issues of truth, meaning, and interpretation. Moreover, they have often been viewed as lending support to such programmes as the 'strong' sociology (...) of knowledge and the turn towards wholesale cultural-relativist doctrines, whether of the Wittgensteinian ('language-games') or Heideggerian (depth-hermeneutic) varieties. Thus Richard Rorty recommends that we should henceforth drop all that old-fashioned talk of 'truth', 'knowledge', or 'reality', since whatever warrants those descriptions from time to time is just the product of some currently favoured language-game or range of elective metaphors. Such ideas have little in common with Quine's general outlook of robust physicalism, nor again - though the case is less clear - with Kuhn's reconsidered approach to these issues as set forth in his 1969 Postscript to The Structure of Scientific Revolutions . However, both thinkers have left themselves open to misconstrual by adopting a sceptical-relativist fallback position in response to the well-known problems with logical empiricism. This essay therefore reviews those problems with reference to alternative, more adequate accounts of what is involved in the process of scientific discovery and theory-change. (shrink)

The main thesis of this paper is that it is not possible to determine the nature of epistemic justification apart from scientific psychological investigation. I call this view the strong thesis of methodological psychologism. Two sub-theses provide the primary support for this claim. The first sub-thesis is that no account of epistemic justification is correct which requires for the possession of at least one justified belief a psychological capacity which humans do not have. That is, the correct account of epistemic (...) justification must be psychologically realistic. The second sub-thesis is that it is not possible to determine whether an account of epistemic justification is psychologically realistic apart from scientific psychological investigation. After defending these subtheses, I point out some interesting consequences of the overall thesis which present a challenge to traditional epistemology. (shrink)

This paper examines the paradox of revisability. This paradox was proposed by Jerrold Katz as a problem for Quinean naturalised epistemology. Katz employs diagonalisation to demonstrate what he takes to be an inconsistency in the constitutive principles of Quine's epistemology. Specifically, the problem seems to rest with the principle of universal revisability which states that no statement is immune to revision. In this paper it is argued that although there is something odd about employing universal revisability to revise itself, there (...) is nothing paradoxical about this. At least, there is no paradox along the lines suggested by Katz. (shrink)

The 20 sup > th /sup > century has been a tumultuous time in psychology -- a century in which the discipline struggled with basic questions about its intellectual identity, but nonetheless managed to achieve spectacular growth and maturation. It’s not surprising, then, that psychology has attracted sustained philosophical attention and stimulated rich philosophical debate. Some of this debate was aimed at understanding, and sometimes criticizing, the assumptions, concepts and explanatory strategies prevailing in the psychology of the time. But much (...) philosophical work has also been devoted to exploring the implications of psychological findings and theories for broader philosophical questions like: Are humans really rational animals? How malleable is human nature? and Do we have any innate knowledge or innate ideas? One particularly noteworthy fact about philosophy of psychology in the 20 sup > th /sup > century is that, in the last quarter of the century, the distinction between psychology and the philosophy of psychology began to dissolve as philosophers played an increasingly active role in articulating and testing empirical theories about the mind and psychologists became increasingly interested in the philosophical underpinnings and implications of their work. Our survey is divided into five sections, each focusing on an important theme in 20 sup > th /sup > century psychology which has been the focus of philosophical attention and has benefited from philosophical scrutiny.

Many psychologists think that concepts should be understood on analogy with the terms of scientific theories, yet the significance of this claim has always been obscure. In this paper, I clarify the psychological content of the theory analogy, focusing on influential pieces by Susan Carey. Once plainly put, the analogy amounts to the view that a mental representation has its semantic properties by virtue of its role in a restricted knowledge structure. One of the commendable things about Carey's work is (...) that, unlike many other psychologists who appeal to the theory analogy, she takes seriously the need to specify how these structures are constrained. At the same time, the constraints she offers are insufficient. Her account also faces challenges from work in the semantics of natural kind terms. (shrink)

Brandom's book Making It Explicit defends Davidson's claim that conceptual thought can arise only on the background of a practice of mutual interpretation, without endorsing the further view that one can be a thinker only if one has the concept of a concept. This involves giving an account of conceptual content in terms of what Brandom calls practical deontic attitudes. In this paper, I make a plea for the conclusion that these practical attitudes are best seen as intentional, but non-conceptually (...) contentful. In particular, I argue that the hypothesis that Brandom's practical deontic attitudes are non-conceptually contentful wouldn't conflict with his view that non-conceptual intentionality is merely derivative. I then explore some of the implications which this hypothesis might have with respect to various forms of «intentional ascent». (shrink)

In his “Epistemology Naturalized,” Quine embraces a form of Humeanism. In this paper, I try to work out the significance of this Humeanism. In particular, I argue that it represents an anti-metaphysical position that Quine shares with Carnap. Crucial to my account is that contrary to much contemporary thinking on metaphysics, Carnap, and Quine following him, recognize both an ontological and an epistemological sense of metaphysics. As commentators have frequently acknowledged, Carnap and Quine disagree over rejecting metaphysics in the ontological (...) sense. I will argue, though, that they agree in rejecting metaphysics in their shared epistemological sense of the term. (shrink)

This essay first traces change in, roughly, the epistemology of the humanities from the 1950s to the 21st century. The second section looks at how the meaning and options in moral philosophy altered in more or less the same period. The last and easily most speculative section examines how these changes permeated American culture, and how professional philosophers responded to the challenges of the new political world they inhabited.

Several recent epistemologists have used understanding-assent links in theories of a priori knowledge and justification, but Williamson influentially argued against the existence of such links. Here I (1) clarify the nature of understanding-assent links and their role in epistemology; (2) clarify and clearly formulate Williamson’s arguments against their existence; (3) argue that Williamson has failed to successfully establish his conclusion; and (4) rebut Williamson’s claim that accepting understanding-assent links amounts to a form of dogmatism.

All’inizio del secolo XX, tre filosofi di Cambridge, Alfred North Whitehead, Bertrand Russell, e Charlie Dunbar Broad, sostennero un’ontologia basata sugli eventi che si riteneva fosse compatibile con la recente teoria della relatività . Gli eventi, perciò, rimpiazzavano le sostanze aristoteliche in veste di componenti primari dell’universo – essi erano concepiti come unità di spazio-tempo che si estendevano spazio-temporalmente e che si sovrapponevano al campo elettromagnetico. Via via che la fisica moderna progrediva, le ontologie basate sugli eventi sembrarono guadagnare ulteriore (...) supporto dal comportamento inaspettato delle particelle elementari descritte a livello quantistico. Dall’espansione dell’universo alle traiettorie delle particelle subatomiche, sembrava che tutto potesse essere sistematicamente interpretato in termini di eventi. (shrink)

Sven-Ove Hansson and Erik Olsson studied in Hansson and Olsson, 103–119 1995) the logical properties of an operation of contraction first proposed by Isaac Levi in Levi. They provided a completeness result for the simplest version of contraction that they call Levi-contraction but left open the problem of characterizing axiomatically the more complex operation of value-based contraction or saturatable contraction. In this paper we propose an axiomatization for this operation and prove a completeness result for it. We argue that the (...) resulting operation is better behaved than various rival operations of contraction defined in recent years. (shrink)

Em linguística gerativa, distinguem-se várias propriedades formais dos sistemas representacionais: a infinidade discreta, a finitude discreta e a infinidade do contínuo. Não é frequente filósofos aplicarem essas distinções ao estudo da forma lógica. O fato de essas distinções serem raramente aplicadas resultou em os filósofos pressuporem, geralmente sem discutir, que todas as formas lógicas apresentam una infinidade discreta, como o faz a linguagem natural. Este artigo defende a existência de outros tipos de forma lógica, além daquela que apresenta infinidade discreta. (...) Na representação mental é possível encontrar formar apresentando infinidade contínua e finitude discreta, além da infinidade discreta. Além disso, tais representações mantêm relações lógicas entre si, parcialmente em virtude dessas formas. Isso equivale à alegação de que o estudo da lógica natural precisa ir além da faculdade de linguagem, abrangendo formas lógicas pertinentes a representações mentais que não se assemelham a sentenças. Isso incluiria formas lógicas pictóricas. O ponto final é que, no estudo da lógica natural, é preciso considerar as formas lógicas representadas a sistemas mentais que antecedem a evolução da linguagem. (shrink)

A glass couldn't contain water unless it contained H2O-molecules. Likewise, a man couldn't be a bachelor unless he was unmarried. Now, the latter is what we would call a conceptual or analytical truth. It's also what we would call a priori. But it's hardly a conceptual or analytical truth that if a glass contains water, then it contains H2O-molecules. Neither is it a priori. The fact that water is composed of H2O-molecules was an empirical discovery made in the eighteenth century. (...) The fact that all bachelors are unmarried was not. But neither is a logical truth, so how do we explain the difference? Two-dimensional semantics is a framework that promises to shed light on these issues. The main purpose of this thesis is to understand and evaluate this framework in relation to various alternatives, to see whether some version of it can be defended. I argue that it fares better than the alternatives. However, much criticism of two-dimensionalism has focused on its alleged inability to provide a proper semantics for certain epistemic operators, in particular the belief operator and the a priori operator. In response to this criticism, a two-dimensional semantics for belief ascriptions is developed using structured propositions. In connection with this, a number of other issues in the semantics of belief ascriptions are addressed, concerning indexicals, beliefs de se, beliefs de re, and the problem of logical omniscience.

The paper analyses theoretical presuppositions of the predominant form of semantic naturalism in contemporary analytic philosophy. The aim is to show that irrespective of the fact that the doctrine of semantic naturalism is grounded in ontological and epistemological naturalism, and is developed on the basis of semantic externalism, this conception of foundational semantics rests on internalist premises, and therefore should be construed as Cartesian. Theories and their interrelations that are assumed by semantic naturalism are explicated by relying on the tripartite (...) interpretation of “the problem of intentionality”. The Cartesian aspects of the assumed theories – and thus of the form of semantic naturalism that is analysed – are then specified in the context of Hilary Putnam’s version of semantic externalism.

I compare Sellars’s criticism of the ‘myth of the given’ with Quine’s criticism of the ‘two dogmas’ of empiricism, that is, the analytic–synthetic distinction and reductionism. In Sections I to III, I present Quine’s and Sellars’s views. In IV to X, I discuss similarities and differences in their views. In XI to XII, I show that Sellars’s arguments against the ‘myth of the given’ are incompatible with Quine’s rejection of the analytic–synthetic distinction.

What is called ``orthodox'' quantum mechanics, as presented in standard foundational discussions, relies on two substantive assumptions --- the projection postulate and the eigenvalue-eigenvector link --- that do not in fact play any part in practical applications of quantum mechanics. I argue for this conclusion on a number of grounds, but primarily on the grounds that the projection postulate fails correctly to account for repeated, continuous and unsharp measurements and that the eigenvalue-eigenvector link implies that virtually all interesting properties are (...) maximally indefinite pretty much always. I present an alternative way of conceptualising quantum mechanics that does a better job of representing quantum mechanics as it is actually used, and in particular that eliminates use of either the projection postulate or the eigenvalue-eigenvector link, and I reformulate the measurement problem within this new presentation of orthodoxy.

In recent years, several authors have reconstructed the relationship between 20th-century economic theory and neuro-psychological research in terms of a three-stage narrative of initial unity, increasing separation, and ongoing reunification. In this article, I draw on major developments in economic theory and neuro-psychological research to provide a descriptive and normative critique of this reconstruction. Moreover, I put forward a reconstruction of the relationship between economics and neuro-psychology that, I claim, better fits both the available empirical evidence and the methodological foundations (...) of these disciplines. In doing so, I argue that recent calls to develop a unified interdisciplinary framework for modeling choice are premised on disputable presuppositions concerning both the domain of economic theory and the relationship between this theory’s axiomatic foundations and empirical findings about the neuro-psychological substrates of choice.

It is not unusual to think of Rorty’s work as a success in rhetoric and a failure in political philosophy. In this article we re-evaluate this assessment by analyzing a typical feature of Rorty’s writing: his frequent use of “we so-and-so.” Taking stock of the existing literature on the subject we discuss how Rorty’s use of the “we” was received by peers and how he himself made sense of it. We then analyze Rorty’s oeuvre in order to show that a (...) better understanding of his rhetorical “we” could make his politico-philosophical “we” more appealing. We suggest that Rorty’s pragmatist take on “ethnos” is preferable to other notions that are currently championed in political theory and philosophy. (shrink)

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

In this article, I examine the reconstruction that Peirce does on analytic/synthetic Kantian division, supported by his phenomenology, semiotic and pragmatism. The analysis of Peirce’s writings on mathematic suggests a notion of a posteriori and necessary analytical truths, that is, propositions that express one belief justified in experience, but whose generalization is valid for all the possible worlds. This was a new idea the time that Peirce formulated it, in 19th Century, and it contrasts with semantic-analytical tradition from Frege and (...) was contested by Quine in 1950’s. Peirce’s notion of analyticity is a result of his discovery of the logic of relatives, which led the philosopher to revise the deductive reasoning, dividing it into corollarial and theorematic, which in turn allow us to understand why mathematics is, simultaneously, deductive and non-trivial.

The exploration of popular culture topics by academic philosophers for non-academic audiences has given rise to a distinctive genre of philosophical writing. Edited volumes with titles such as Black Sabbath and Philosophy or Buffy the Vampire Slayer and Philosophy contain chapters by multiple philosophical authors that attempt to bring philosophy to popular audiences. Two dominant models have emerged in the genre. On the pedagogical model, authors use popular culture examples to teach the reader philosophy. The end is to promote philosophical (...) literacy, defined as acquaintance with the key problems, ideas, and figures in the history of philosophy. In contrast, on the applied philosophy model, authors use philosophy to open up new dimensions of the popular culture topic for fans. The end is to illustrate the value of philosophy in understanding the popular culture topic, and ultimately, to demonstrate the value of philosophy in general. Taking stock of the relative strengths and weaknesses of these two models provides an opportunity to reflect more broadly on whether, why, and how philosophers should engage the public. (shrink)

The recent enthusiasm for “participation” in agricultural development has fueled the development of new approaches to research and extension. The rhetoric of “participation” extends the horizons of agricultural research and extension beyond technical problem-solving. Yet in practice few of the personal, political, and experiential aspects of this process are addressed. This paper aims to draw attention to these elements of practice and to locate research and extension within wider social processes. Through a critique of conventional methodological strategies, this paper considers (...) the possibilities offered by “participatory” alternatives. Considering the scope and objectives of agricultural development raises a series of methodological questions: What counts as knowledge? Who defines and represents this knowledge? Whose knowledge counts? Knowledge for what? Knowledge for whom?The paper goes on to assess a number of these “new” methodologies, within and beyond agricultural development. Through a consideration of their strengths and weaknesses, a series of further issues are highlighted for future methodological development. It is argued that for agricultural research and extension to acknowledge process, closer attention needs to be paid to context. The activities of research and extension need to be set in time. Strategies are needed to explore and address diversity and difference in communities. Situating the actors and agencies involved in development within relations of power involves addressing—and redressing—the nature of interactions between these actors. These changes require not an ever increasing array of methods, it is argued, but new approaches to learning. (shrink)

In this paper, I challenge an influential understanding of naturalization according to which work on traditional problems in the philosophy of law should be replaced with sociological or psychological explanations of how judges decide cases. W.V. Quine famously proposed the ‘naturalization of epistemology’. In a prominent series of papers and a book, Brian Leiter has raised the intriguing idea that Quine’s naturalization of epistemology is a useful model for philosophy of law. I examine Quine’s naturalization of epistemology and Leiter’s suggested (...) parallel and argue that the parallel does not hold up. Even granting Leiter’s substantive assumption that the law is indeterminate, there is no philosophical confusion or overreaching in the legal case that is parallel to the philosophical overreaching of Cartesian foundationalism in epistemology. Moreover, if we take seriously Leiter’s analogy, the upshot is almost the opposite of what Leiter suggests. The closest parallel in the legal case to Quine’s position would be the rejection of the philosophical positions that lead to the indeterminacy thesis. (shrink)

Thesis (Ph. D.)--University of Hawaii at Manoa, 1996.

With resources hinted at in different ways by both Duhem and Quine, it is argued that some of their misgivings about empirical confirmation, or crucial experiments, may be exaggerated or unfounded; and that such experiments, suitably conceived, can give good meaning to empirical sentences. With appropriate meanings one can then wonder about synonymy and analyticity.

On what seems to be the best interpretation, what Quine calls 'the problem of synonymy' in Two Dogmas is the problem of approximating the extension of our pretheoretic concept of synonymy by clear and respectable means. Quine thereby identified a problem which he himself did not think had any solution, and so far he has not been proven wrong. Some difficulties for providing a solution are discussed in this paper.

The relation between logic and philosophy of science, often taken for granted, is in fact problematic. Although current fashionable criticisms of the usefulness of logic are usually mistaken, there are indeed difficulties which should be taken seriously — having to do, amongst other things, with different scientific mentalities in the two disciplines (section 1). Nevertheless, logic is, or should be, a vital part of the theory of science. To make this clear, the bulk of this paper is devoted to the (...) key notion of a scientific theory in a logical perspective. First, various formal explications of this notion are reviewed (section 2), then their further logical theory is discussed (section 3). In the absence of grand inspiring programs like those of Klein in mathematics or Hilbert in metamathematics, this preparatory ground-work is the best one can do here. The paper ends on a philosophical note, discussing applicability and merits of the formal approach to the study of science (section 4). (shrink)

In a recent paper, “The Concept of Logical Consequence,” W. H. Hanson criticizes a formal-structural characterization of logical consequence in Tarski and Sher. Hanson accepts many principles of the formal-structural view. Relating to Sher 1991 and 1996a, he says.

Elizabeth Anscombe’s classic paper Causality and Determination claims that causation can be perceived. It also defends causal singularism, the idea that the causal relation is fundamentally between the particular cause and effect, and does not depend on regularities holding elsewhere in the universe. But does the former furnish an argument for the latter? The present paper analyses a special type of causal experience involving emotional reactions to present stimuli; for instance, being frightened by a spider. It argues that such experiences (...) are strongly local, in the sense that they justify belief in a local causal relation independently of our knowledge about events elsewhere in the universe. If this analysis is correct, Humean regularity theories of causation are false; and all other non-singularist theories of causation face a difficult explanatory challenge. This means that the case for causal singularism comes out considerably strengthened. (shrink)
