If successful scientific inquiry is to be possible, there must be a world that is independent of how we believe it to be, and in which there are kinds and laws; and we must have the sensory apparatus to perceive particular things and events, and the capacity to represent them, to form generalized explanatory conjectures, and check how these conjectures stand up to further experience. Whether these preconditions are met is not a question the sciences can answer; it is specifically (...) philosophical. This is why the myriad forms of scientistic philosophy in vogue today (neurophilosophy, experimental philosophy, naturalized metaphysics, evangelical-atheist reductionism, etc), are all hollow at the core. Does this mean we must return to the old, a priori analytic model? No! What is needed instead is scientific philosophy in the sense Peirce articulated more than a century ago: philosophy motivated by a genuine desire to discover the truth, and relying not solely on reason but also on experience—only not the special, recherché experience required by the sciences, but close attention to aspects of everyday experience so familiar we hardly notice them.

The reformist philosophy of the classical pragmatist tradition has gradually evolved into the now-fashionable revolutionary styles of pragmatism, some scientistic, some literary. This evolution is traced from Peirce, James, Dewey, and Mead, through Schiller, Lewis, Hook,and Quine, to Rorty’s literary-political neo-pragmatism. Rather than get hung up on the question of which variants qualify as authentic pragmatism, it is better — more fruitful, and appropriately forward looking— to ask what we can learn from the older tradition, and what we can salvage (...) from the new.

Although the AGM theory established a paradigm for the theory of belief revision, which is generally regarded as a kind of standard in the field, it is also frequently criticized as inadequate because it neglects justificational structures. Other theories of belief revision are similarly remiss in this regard. So far, little has been done to address this shortcoming. This paper aims to fill this gap. Following a critical analysis of the AGM theory, a justification operator is introduced as a formal (...) means to incorporate justificational structures into a belief revision theory. An AGM style belief revision theory is proposed that is based on such a justification operator. The theory is presented in an axiomatic form. Representation theorems link the axioms with constructive belief change mechanisms. The proposed theory addresses the problems of the AGM theory and similar approaches that neglect justificational structures. (shrink)

Belief revision theories aim to model the dynamics of epistemic states. Besides beliefs, epistemic states comprise most importantly justificational structures. Typically, belief revision theories, however, model the dynamics of beliefs while neglecting justificational structures over and above logical relations. Despite some awareness that this approach is problematic, how devastating the consequences of this neglect are has not yet been fully grasped. In this paper, I argue that taking justificational structures into account could solve four well-known problems of belief revision.

El renacimiento del interés por Hegel en el mundo filosófico se apoya en varios puntos: la superación del dualismo entre el esquema conceptual y el contenido, la disipación del mito de lo dado y el inferencialismo. En relación con el primer punto, John McDowell intenta superar aquel dualismo, echando mano de un Hegel cuya retórica requiere de una domesticación. Se intenta iluminar el alcance y algunas limitaciones de esta propuesta, en su intento por desmontar la filosofía del permanente movimiento entre (...) el mito de lo dado o la inmediatez, por un lado, y el coherentismo, por el otro. The revival of interest in Hegel in contemporary philosophical world is based on several reasons: the overcoming of the dualism between conceptual scheme and content, the dissipation of the myth of the given, and inferentialism. Regarding the first point, John McDowell tries to overcome this dualism by making use of Hegel, whose rhetoric requires domestication. The article seeks to illuminate the scope and some limitations of this proposal in its attempt to dismantle philosophy from a permanent movement between the myth of the given or immediacy, on the one hand, and coherentism, on the other.

This paper concerns local yet systematic problems of contrastive underdetermination of model choice in cognitive neuroscience debates about the so-called two visual systems hypothesis. The underdetermination problem is systematically generated by the way certain assumptions about the representationalist nature of computation are translated into experimental practice. The problem is that behavioural data underdetermine the choice between competing representational models. In this paper, I diagnose how these assumptions generate underdetermination problems in the choice between competing functional models of perception–action. Using the (...) tools of philosophy of science, I describe the type of underdetermination and sketch a possible cure. (shrink)

Our scientific theories, like our cognitive structures in general, consist of propositions linked by evidential, explanatory, probabilistic, and logical connections. Those theoretical webs ‘impinge on the world at their edges,’ subject to a continuing barrage of incoming evidence. Our credences in the various elements of those structures change in response to that continuing barrage of evidence, as do the perceived connections between them. Here we model scientific theories as Bayesian nets, with credences at nodes and conditional links between them modelled (...) as conditional probabilities. We update those networks, in terms of both credences at nodes and conditional probabilities at links, through a temporal barrage of random incoming evidence. Robust patterns of punctuated equilibrium, suggestive of ‘normal science’ alternating with ‘paradigm shifts,’ emerge prominently in that change dynamics. The suggestion is that at least some of the phenomena at the core of the Kuhnian tradition are predictable in the typical dynamics of scientific theory change captured as Bayesian nets under even a random evidence barrage.

It is sometimes suggested that Collingwood's philosophy of history is decidedly anti-naturalist and argues for a complete separation between history and the natural sciences. The purpose of this paper is to examine this suggestion and to argue that Collingwood's conception of the relationship between history and natural sciences is much more subtle and nuanced than such a view would allow for. In fact, there is little in Collingwood to offend contemporary naturalistic sensibilities reasonably construed. The impression that Collingwood's views are (...) incompatible with naturalism stems, in part, from an overly Kantian interpretation of the idea of rationality, as applied to historical agents, in terms of transcendentally fixed norms. This difficulty, however, does not arise if we opt for a more Hegelian interpretation of rationality in terms of continuity in thought, which Collingwood himself seemed to favor. Examining Collingwood's pronouncements on these topics leads one to the conclusion that, while objecting to the excesses of early naturalism, Collingwood saw no insurmountable obstacles to the reconciliation of science and history and their potential collaboration in some areas.

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)

Popper emphasised both the problem-solving nature of human knowledge, and the need to criticise a scientific theory as strongly as possible. These aims seem to contradict each other, in that the former stresses the problems that motivate scientific theories while the one ignores the character of the problems that led to the formation of the theories against which the criticism is directed. A resolution is proposed in which problems as such are taken as prime in the search for knowledge, and (...) subject to discussion. This approach is then applied to the problem of induction. Popper set great stake to his solution of it, but others doubted its legitimacy, in ways that are clarified by changing the form of the induction problem itself. That change draws upon logic, which is the subject of another application: namely, in contrast to Popper’s adhesion to classical logic as the only welcome form (because of the maximal strength of criticism that it dispenses), can other logics be used without abandoning his philosophy of criticism?

In this paper, I argue that various disputes in ontology have important ramifications and so are worth taking seriously. I employ a criterion according to which whether a dispute matters depends on how integrated it is with the rest of our theoretical projects. Disputes that arise from previous tensions in our theorizing and have additional implications for other issues matter, while insular disputes do not. I apply this criterion in arguing that certain ontological disputes matter; specifically, the disputes over concrete (...) possible worlds and coincident material objects. Finally, I consider how one could show that some ontological disputes do not matter, using a Platonism/nominalism dispute as an example. (shrink)

This paper deals with some formal properties of objects that are supposed to be internal to persons, that is, mental structures and mental functions. Depending on the ways of talking about these internal objects, they will appear different. Two types of discourse will be presented, to be called the realist and the nominalist discourses, and for eachdiscourse I will focus upon the construction of `self'.The realist discourse assumes an identity between the person and his construction of himself. I will illustrate (...) this discourse in terms of Descartes' ideas on himself as a `thinking substance'. The nominalist discourse assumes an impossibility to attain this identity, and instead to imply a complementarity between the person and his self-construction. I will illustrate this discourse in terms of the problems both William James and Sartre discerned when a conscious person chases after his own consciousness (termed `judging thought' and `pour-soi' respectively).

It is often claimed that the debate between presentism and eternalism is merely verbal, because when we use tensed, detensed or tenseless notions of existence, there is no difference in the accepted metaphysical statements between the adherents of both views. On the contrary, it is shown in this paper that when we express their positions making use, in accordance with intentions of the presentists and the eternalists, of the tensed notion of existence (in the case of the presentists) and the (...) detensed or tenseless notion (in the case of the eternalists), the controversy remains deep and very important for us, because both ontological claims express a different attitude to the existence of the flow of time. It is shown that not only does the proposed approach to presentism and eternalism exactly express the intentions of the adherents of both views but it also offers a better understanding of them joining together seemingly different theses maintained by the presentists and the eternalists, and explaining at the same time the dynamism of the presentists' ontology. The paper takes for granted that we should assess metaphysical theories in a similar way as we assess scientific theories, that is on the basis of their explanatory value. (shrink)

In this paper I examine Crispin Wright's modal anti-realism as based on the availability of a certain attitude of Caution towards judgements of necessity. I think that Wright's account should be attractive in several ways for modal theorists with an anti-realist bend. However, the attitude of Caution to which it appeals has attracted some controversy. Wright himself has later come to doubt whether Caution is ultimately coherent. Here I first address Wright's worries concerning the coherence of Caution and show that (...) they are unfounded. But then I argue that although the attitude of Caution is coherent, it cannot provide a suitable basis for a non-eliminativist account of necessity. I offer two different objections against Caution. I argue that Wright's appeal to Caution, if successful, would show not only that modal judgement is non-objective but also that it is dispensable. Thus, I claim that appeal to Caution would seem to serve more as a threat against a non-eliminativist account of necessity, rather than as a potential adequate basis for it. However, I argue that Wright's appeal to Caution is unsuccessful, for there is no genuine Caution: Caution is a mere verbal attitude. (shrink)

Philosophical research tends to be done separately from empirical research, but this makes it difficult to tackle questions which require both. To make it easier to address these hybrid research questions, I argue that we should sometimes combine philosophical and empirical investigations. I start by describing a continuum of research methods from data collecting and analysing to philosophical arguing and conceptualising. Then, I outline one possible middle-ground position where research is equally philosophical and empirical: the Community of Inquiry reconceived as (...) a research method. In this method, a group of participants engage in philosophical discussion and dialogue to answer the research question . I argue that this collaborative philosophical inquiry, moderated by a philosopher, provides a new method for collecting and testing data. The results are philosophical positions and arguments blended with empirical findings. Next, I illustrate how I used this philosophical–empirical method in a recent study to evaluate the strength of educational metaphors. I conclude that the Community of Inquiry is a viable means of combining philosophical and empirical research, and a new and worthwhile method for research in education. (shrink)

Knowledge representation is a central issue for Artificial Intelligence and the Semantic Web. In particular, the problem of representing n-ary relations in RDF-based languages such as RDFS or OWL by no means is an obvious one. With respect to previous attempts, we show why the solutions proposed by the well known W3C Working Group Note on n-ary relations are not satisfactory on several scores. We then present our abstract model for representing n-ary relations as directed labeled graphs, and we show (...) how this model gives rise to a new ontological pattern for the representation of such relations in the Semantic Web. To this end, we define PROL. PROL is an ontological language designed to express any n-ary fact as a parametric pattern, which turns out to be a special RDF graph. The vocabulary of PROL is defined by a simple RDFS ontology. We argue that the parametric pattern may be particularly beneficial in the context of the Semantic Web, in virtue of its high expressive power, technical simplicity, and faithful meaning rendition. Examples are also provided. (shrink)

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.

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)

The final-year undergraduate dissertation is commonplace in Education Studies programmes across the world and yet its philosophical assumptions are complex and not always questioned. In England there is evidence to suggest a tacit preference for empiricism in textbooks designed to support early researchers. This brings, we suggest, problems associated with dualism, instrumentalism and of accounting for value, redolent of the dilemmas that emerge from Hume’s empiricist epistemology. The paper suggests that if argumentation were explicitly taught to undergraduates it may help (...) oversee the more judicious use of empirical approaches that are currently privileged in dissertation guidance.

Multivariate pattern analysis, or MVPA, has become one of the most popular analytic methods in cognitive neuroscience. Since its inception, MVPA has been heralded as offering much more than regular univariate analyses, for—we are told—it not only can tell us which brain regions are engaged while processing particular stimuli, but also which patterns of neural activity represent the categories the stimuli are selected from. We disagree, and in the current paper we offer four conceptual challenges to the use of MVPA (...) to make claims about neural representation. Our view is that the use of MVPA to make claims about neural representation is problematic. (shrink)

Is normative theory grounded in ontology and if so, how? Taking a debate between Kwame Gyekye and Thaddeus Metz as my point of departure, my aim in this article is to show that something normative does indeed follow from ontological views: The social ontological, I maintain, circumscribes the normative without, however, fully determining its content. My argument proceeds in two steps: First, I argue that our social ontological position constrains what kind of normative theory we may plausibly defend. A relational (...) ontology as defended by Gyekye entails a relational normative theory, whereas an atomist ontology calls for an individualist normative approach and a collectivist ontology for a strong communitarian one. Second, this link between the ontological and the normative has substantive implications for how to interpret the normative content of a theory; it entails interpreting normative values in light of the appropriate kind of normative thought. I illustrate the importance of this implication by showing that it suggests a decidedly relational reading of the core value of well-being in Gyekye’s moderate communitarianism, that resolves the alleged tension between communal and individual values in his account.

There is a close systematic relationship between panentheism, as a metaphysical theory about the relation between God and the world, and transhumanism, the ethical demand to use the means of the applied sciences to enhance both human nature and the environment. This relationship between panentheism and transhumanism provides a ‘cosmic’ solution to the problem of evil: on panentheistic premises, the history of the world is the one infinite life of God, and we are part of the one infinite divine being. (...) We ourselves are therefore responsible for the future development of the life of the divine being. We should therefore use the means provided by the natural sciences to develop the history of the world in such a way that the existence of evil shall be overcome and shall no longer be part of the divine being in whom we move and live and have our being. The metaphysics of panentheism leads to the ethics of transhumanism. (shrink)

In this paper I will try to defend a quasi-naturalistic interpretation of J.L. Austin’s work. I will rely on P. Kitcher’s 1992 paper “The Naturalists Return” to compile four general criteria by which a philosopher can be called a naturalist. Then I will turn to Austin’s work and examine whether he meets these criteria. I will try to claim that versions of such naturalistic elements can be found in his work.

Empiricist philosophers like Carnap invoked analyticity in order to explain a priori knowledge and necessary truth. Analyticity was “truth purely in virtue of meaning”. The view had a deflationary motivation: in Carnap’s proposal, linguistic conventions alone determine the truth of analytic sentences, and thus there is no mystery in our knowing their truth a priori, or in their necessary truth; for they are, as it were, truths of our own making. Let us call this “Carnapian conventionalism”, conventionalismC and cognates for (...) short. This conventionalistC explication of the a priori has been the target of sound criticisms. Arguments like Quine’s in “Truth by Convention” are in our view decisive: the truth of conventionalismC requires that the class of logical truths and logical validities be reductively accounted for as conventionally established; however, no such reduction is forthcoming, because logic is needed to generate the entire class from any given set of conventions properly so-called. Granted that conventionalismC is untenable, we want to take issue with a different, usually made criticism. Although the argument uncovers some difficulties for the way conventionalist claims are defended by some of its advocates, we will try to show that it fails. The criticism thus stands in the way of a proper appreciation of why the Carnapian account of the a priori is not correct. We will try to illustrate this by showing that the criticism we will dispute would dispose of conventionalist claims not only regarding philosophically problematic cases – logical and mathematical truths –, but also regarding cases for which they have some prima facie plausibility. One such case is that of truths that follow from mere abbreviations, “nominal” definitions; ‘someone is a bachelor if and only if he is an unmarried adult male’ can serve at this point for illustration. We will try to articulate a clear sense in which the contents of assertion such as this can be truths by convention. We do not need to prove that a conventionalist claim is true in those cases; it is enough for us to show that it is intelligible, for the arguments we will confront question even this. (shrink)

Science educators and those who investigate science learning have tended, for good reason, to focus their attention on students' conceptual development, Such a focus is, however, too narrow to provide full and proper understanding of the complexities of original science learning. Recently developmental cognitive psychologists have called on the work of postpositivistic philosophers of science, especially Thomas Kuhn, to bolster their research into conceptual development in science acquisition. What these psychologists have not recognized is that Kuhn's position is actually a (...) derivative of Wittgenstein's methodological nominalism, a viewpoint far more favorable to behaviorism than cognitive psychology. After drawing out some of the consequences of this fact for the developmental cognitive psychologist program for studying science learning, we suggest our own radical alternative. Drawing on Floden, Buchmann and Schwille's idea of “Breaking with Everyday Experience” we propose an alternative notion of original science learning in terms of Alfred Schutz's modification of Williams James' many worlds thesis. The many worlds thesis will allow us to better understand students' difficulty in learning idealized worlds such as science, worlds that represent a discontinuous break with ordinary everyday practical experience.

The paper reviews the current state of play around anti-representationalist attempts at countering Clark and Toribio’s representation-hunger thesis. It introduces a distinction between different approaches to Chemero’s Radical embodied cognition thesis in the form of, on the one hand, those pushing a hard line and, on the other, those who are more relaxed about their anti-representationalist commitments. In terms of overcoming Clark and Toribio’s thesis, hardliners seek to avoid any mentioning of mental content in the activity they purport to explain. (...) Yet, the paper argues, adopting a hard line complicates this endeavor considerably and unnecessarily. Those promoting a relaxed REC, however, are better off in that they have no problem in recognizing that some types of cognition are hybrid. By turning to Hutto and Myin’s Radical Enactivism as a prime example of a relaxed approach to the REC thesis, the paper points towards the lack of continuity between covariant information and informational content as the gap that would necessarily have to be closed in order for RECers to, once and for all, be able to dismiss Clark and Toribio’s hypothesis that certain kinds of cognition are per definition off-limits to anti-representationalism.

Decision theorists have attempted to accommodate several violations of decision theory’s axiomatic requirements by modifying how agents’ choice options are individuated and formally represented. In recent years, prominent authors have worried that these modifications threaten to trivialize decision theory, make the theory unfalsifiable, impose overdemanding requirements on decision theorists, and hamper decision theory’s internal coherence. In this paper, I draw on leading descriptive and normative works in contemporary decision theory to address these prominent concerns. In doing so, I articulate and (...) assess several different criteria for individuating and formally representing agents’ choice options. (shrink)

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.

ABSTRACT Bernard Yack’s The Longing for Total Revolution is not just an important study of an extremely influential strain of post-Kantian philosophy, which according to Yack culminated in both Marx and Nietzsche. It also exemplifies an unusual approach to the history of thought: a form of critical genealogy that, unlike the Nietzschean and Foucauldian variants, seeks intellectual charity by ascribing mistaken ideas not to non-ideational psychological or social sources, but to a web of beliefs that would have obscured from fully (...) rational historical actors the mistakenness of the idea being genealogized. This approach to intellectual history can justify the history of thought on logical grounds that are unavailable to those who attempt to justify it on the basis of the inherent interest of the past or the usefulness of intellectual history in providing resources for present-day use.

In formulating a theory of perception that does justice to the embodied and enactive nature of perceptual experience, proprioception can play a valuable role. Since proprioception is necessarily embodied, and since proprioceptive experience is particularly integrated with one’s bodily actions, it seems clear that proprioception, in addition to, e.g., vision or audition, can provide us with valuable insights into the role of an agent’s corporal skills and capacities in constituting or structuring perceptual experience. However, if we are going to have (...) the opportunity to argue from analogy with proprioception to vision, audition, touch, taste, or smell, then it is necessary to eschew any doubts about the legitimacy of proprioception’s inclusion into the category of perceptual modalities. To this end, in this article, I (1) respond to two arguments that Shaun Gallagher ( 2003 ) presents in “Bodily self-awareness and objectperception” against proprioception’s ability to meet the criteria of object perception, (2) present a diagnosis of Gallagher’s position by locating a misunderstanding in the distinction between proprioceptive information and proprioceptive awareness, and (3) show that treating proprioception as a perceptual modality allows us to account for the interaction of proprioception with the other sensory modalities, to apply the lessons we learn from proprioception to the other sensory modalities, and to account for proprioceptive learning. Finally, (4) I examine Sydney Shoemaker’s ( 1994 ) identification constraint and suggest that a full-fledged notion of object-hood is unnecessary to ground a theory of perception. (shrink)

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 pluralist sheds the more traditional ideas of truth and ontology. This is dangerous, because it threatens instability of the theory. To lend stability to his philosophy, the pluralist trades truth and ontology for rigour and other ‘fixtures’. Fixtures are the steady goal posts. They are the parts of a theory that stay fixed across a pair of theories, and allow us to make translations and comparisons. They can ultimately be moved, but we tend to keep them fixed temporarily. Apart (...) from considering rigour of proof as a fixture, I discuss fixed models, invariant notions and fixed information about objects across theories. There are other fixtures, but it is enough to start with these. (shrink)

An odd dissensus between confident metaphysicians and neopragmatist antimetaphysicians pervades early twenty-first century analytic philosophy. Each faction is convinced their side has won the day, but both are mistaken about the philosophical legacy of the twentieth century. More historical awareness is needed to overcome the current dissensus. Lewis and his possible-world system are lionised by metaphysicians; Quine’s pragmatist scruples about heavy-duty metaphysics inspire antimetaphysicians. But Lewis developed his system under the influence of his teacher Quine, inheriting from him his empiricism, (...) his physicalism, his metaontology, and, I will show in this paper, also his Humeanism. Using published as well as never-before-seen unpublished sources, I will make apparent that both heavy-duty metaphysicians and neopragmatist antimetaphysicians are wrong about the roles Quine and Lewis played in the development of twentieth-century philosophy. The two are much more alike than is commonly supposed, and Quine much more instrumental to the pedigree of current metaphysics. (shrink)

Koopman’s book revolves around the notion of transition, which he proposes is one of the central ideas of the pragmatist tradition but one which had not previously been fully articulated yet nevertheless shapes the pragmatist attitude in philosophy.

One of the consequences of transitionalism is the understanding of critique and inquiry as historical pro...

I explore three points about the relationship between C.I. Lewis’s conceptual pragmatism and W.V. Quine’s naturalized epistemology inspired by Robert Sinclair’s Quine, Conceptual Pragmatism, and the Analytic-Synthetic Distinction. First, I highlight Lewis’s long-standing commitment to Platonism about meaning and its connection to his reflective philosophical method and rejection of a linguistic account of analyticity. Second, I consider Sinclair’s claim that “Lewis’s epistemology provides no indication concerning how, despite different sensory experiences, we still come to agree on what we are talking (...) about and what counts as evidence” (2022, 113). I find more hints, especially in Lewis’s account of how we verify that two people share meaning in common. However, some of the pragmatic and broadly empirical factors Lewis appeals to are not part of Quine’s naturalized epistemology. Finally, I relate these points to Quine’s (1953/1980) claim to advance a more “thorough pragmatism” than Lewis. Quine does not say much about action, value, and ethics, but these are central parts of Lewis’s conceptual pragmatism and a source of his reluctance to abandon those parts of his epistemology that Sinclair argues Quine found dispensable.

Although during the last decades the philosophy of chemistry has greatly extended its thematic scope, the main difficulties appear in the attempt to link the chemical description of atoms and molecules and the description supplied by quantum mechanics. The aim of this paper is to analyze how the difficulties that threaten the continuous conceptual link between molecular chemistry and quantum mechanics can be overcome or, at least, moderated from the perspective of BM. With this purpose, in “The quantum-mechanical challenges” section (...) the foundational incompatibility between chemical and SQM descriptions will be briefly recalled. “Bohmian mechanics” section will be devoted to explain the main features of BM. In “Empirical equivalence and underdetermination” section, the consequences of the empirical equivalence between SQM and BM will be discussed. Finally, in the Conclusion, we will stress the scope of the obtained conclusions and the philosophical difficulties that still remain even after adopting BM for foundational purposes. (shrink)

Pragmatism is usually viewed as a unifed school, movement or tradition. Lists of its most important tenets typically include advocacy of open inquiry, pursued with an awareness of human fallibility, a view of justifcation that appeals to shared experience in all its manifestations – aesthetic, religious, moral, political and scientifc – and a conception of philosophy as a practice interwoven with problems of contemporary life. While disagreements among pragmatists are widely acknowledged, they are most often treated as easily resolved or (...) of marginal importance given the substantial body of doctrine that pragmatists are thought to share. I argue that this view of pragmatism obscures important philosophical differences among its proponents, to the serious detriment of our understanding of the tradition. I point out that fgures most often credited with advancing pragmatism – Charles Peirce, William James, John Dewey, W.V. Quine, Hilary Putnam and Richard Rorty – defend signifcantly divergent views, views that are anything but easy to reconcile. Their differences go to the very heart of how pragmatism is to be understood and defended and present serious obstacles to any characterization of it as a tradition with a common philosophical method, purpose or core set of doctrines. Pragmatism is far more diverse, subtle and diffcult to come to terms with than contemporary accounts of what is living and dead in it commonly presume. (shrink)

The problem with reductionism in biology is not the reduction, but the implicit attitude of determinism that usually accompanies it. Methodological reductionism is supported by deterministic beliefs, but making such a connection is problematic when it is based on an idea of determinism as fixed predictability. Conflating determinism with predictability gives rise to inaccurate models that overlook the dynamic complexity of our world, as well as ignore our epistemic limitations when we try to model it. Furthermore, the assumption of a (...) strictly deterministic framework is unnecessarily hindering to biology. By removing the dogma of determinism, biological methods, including reductive methods, can be expanded to include stochastic models and probabilistic interpretations. Thus, the dogma of reductionism can be saved once its ties with determinism are severed. In this paper, I analyze two problems that have faced molecular biology for the last 50 years—protein folding and cancer. Both cases demonstrate the long influence of reductionism and determinism on molecular biology, as well as how abandoning determinism has opened the door to more probabilistic and unconstrained reductive methods in biology.

This paper examines the problem of extending the programme of mathematical constructivism to applied mathematics. I am not concerned with the question of whether conventional mathematical physics makes essential use of the principle of excluded middle, but rather with the more fundamental question of whether the concept of physical infinity is constructively intelligible. I consider two kinds of physical infinity: a countably infinite constellation of stars and the infinitely divisible space-time continuum. I argue (contrary to Hellman) that these do not.
