Some philosophers argue that many contemporary debates in metaphysics are “illegitimate,” “shallow,” or “trivial,” and that “contemporary analytic metaphysics, a professional activity engaged in by some extremely intelligent and morally serious people, fails to qualify as part of the enlightened pursuit of objective truth, and should be discontinued” (Ladyman and Ross, Every thing must go: Metaphysics naturalized , 2007 ). Many of these critics are explicit about their sympathies with Rudolf Carnap and his circle, calling themselves ‘neo-positivists’ or ‘neo-Carnapians.’ Yet (...) despite the fact that one of the main conclusions of logical positivism was that metaphysical statements are meaningless, many of these neo-positivists are themselves engaged in metaphysical projects. This paper aims to clarify how we may see a neo-positivist metaphysics as proceeding in good faith, one that starts with serious engagement with the findings of science, particularly fundamental physics, but also has room for traditional, armchair methods.

Abstract Artificial language philosophy (also called ‘ideal language philosophy’) is the position that philosophical problems are best solved or dissolved through a reform of language. Its underlying methodology—the development of languages for specific purposes—leads to a conventionalist view of language in general and of concepts in particular. I argue that many philosophical practices can be reinterpreted as applications of artificial language philosophy. In addition, many factually occurring interrelations between the sciences and philosophy of science are justified and clarified by the (...) assumption of an artificial language methodology.

This paper explores the work of Nicolas Rashevsky, a Russian émigré theoretical physicist who developed a program in "mathematical biophysics" at the University of Chicago during the 1930s. Stressing the complexity of many biological phenomena, Rashevsky argued that the methods of theoretical physics -- namely mathematics -- were needed to "simplify" complex biological processes such as cell division and nerve conduction. A maverick of sorts, Rashevsky was a conspicuous figure in the biological community during the 1930s and early 1940s: he (...) participated in several Cold Spring Harbor symposia and received several years of funding from the Rockefeller Foundation. However, in contrast to many other physicists who moved into biology, Rashevsky's work was almost entirely theoretical, and he eventually faced resistance to his mathematical methods. Through an examination of the conceptual, institutional, and scientific context of Rashevsky's work, this paper seeks to understand some of the reasons behind this resistance. (shrink)

This study examines the relativistic aspects of Arnold Schoenberg's harmonic and aesthetic theories in the light of a framework of ideas presented in the early writings of Ludwig Wittgenstein, the logician, philosopher of language, and Schoenberg's contemporary and Austrian compatriot. The author has identified correspondences between the writings of Schoenberg, the early Wittgenstein, and the Vienna Circle of philosophers, on a wide range of topics and themes. Issues discussed include the nature and limits of language, musical universals, theoretical conventionalism, word-to-world (...) correspondence in language, the need for a fact- and comparison-based approach to art criticism, and the nature of music-theoretical formalism and mathematical modeling. Schoenberg and Wittgenstein are shown to have shared a vision that is remarkable for its uniformity and balance, one that points toward the reconciliation of the positivist-relativist dualism that has dominated recent discourse in music theory. Contrary to earlier accounts of Schoenberg's harmonic and aesthetic relativism, this study identifies a solid epistemological core underlying his thought, a view that was very much in step with Wittgenstein and the Vienna Circle, and thereby with the most vigorous and forward-looking stream in early twentieth century intellectual history.

Abstract. Value judgments are meaningless. This thesis was one of the notorious tenets of Carnap’s mature logical empiricism. Less well known is the fact that in the Aufbau values were con-sidered as philosophically respectable entities that could be constituted from value experiences. About 1930, however, values were banished to the realm of meaning-less me-taphysics, and Carnap came to endorse a strict emotivism. The aim of this paper is to shed new light on the question why Carnap abandoned his originally positive (...) attitude concerning values. It is argued that Carnap’s non-cognitivist attitude was the symptom of a deep-rooted and never properly dissolved tension be-tween his conflicting inclinations towards Neokantianism and Lebensphilosophie. In America Carnap’s non-cognitivism became a major obstacle for a closer collaboration between lo-gical empiricists and American pragmatists. Carnap’s persisting ad---herence to the dualism of practical life and theoretical science was the ultimate reason why he could not accept Morris’s and Kaplan’s pragmatist the-ses that cognitivism might well are compatible with a logical and empiricist scientific philosophy.

Gideon Rosen, Brian Leiter, and Catarina Dutilh Novaes raise deep questions about the arguments in Morality and Mathematics (M&M). Their objections bear on practical deliberation, the formulation of mathematical pluralism, the problem of universals, the argument from moral disagreement, moral ‘perception’, the contingency of our mathematical practices, and the purpose of proof. In this response, I address their objections, and the broader issues that they raise.

In this paper, I look at Susan Stebbing’s articles and reviews that critically engage logical positivism. These appeared before the publication of A.J. Ayer’s Language, Truth and Logic and helped shape the early British reception of logical positivism. I highlight Stebbing’s adoption of G.E. Moore’s tripartite distinction between knowing a proposition, understanding it, and giving an analysis of it and, in light of this distinction, her focus on whether the principle of verifiability can ground a plausible account of communication. Stebbing (...) thinks not, and I reconstruct her reasons, as well as her own account of communication. In doing this, I relate her criticisms to her rejection of methodological solipsism and her dissatisfaction with the logical positivist treatment of statements about other minds and the past. I also argue that Stebbing’s work provides a bridge to later criticisms of logical positivism from ordinary language philosophers. Foregrounding Stebbing’s engagement with logical positivism, especially her focus on communication, paints a fuller picture of how the logical positivists came to be part of analytic philosophy despite having different concerns than many of the British philosophers engaging their work.

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)

Carnap’s seminal ‘Empiricism, Semantics and Ontology’ makes important use of the notion of a framework and the related distinction between internal and external questions. But what exactly is a framework? And what role does the internal/external distinction play in Carnap’s metaontology? In an influential series of papers, Matti Eklund has recently defended a bracingly straightforward interpretation: A Carnapian framework, Eklund says, is just a natural language. To ask an internal question, then, is just to ask a question in, say, English. (...) To try to ask an external question is to try, absurdly, to ask a question in no language at all. Finding that so trivial an I/e distinction can’t help to explain Carnap’s deflationary metaontology, Eklund is led to attribute to Carnap a view he calls ontological pluralism. In this paper, I show that Eklund misreads Carnap, and I argue that this misreading obscures fundamental features of Carnap’s philosophy. I then defend an account of frameworks as what Carnap called semantical systems, and I place this account in the context of Carnap’s philosophical program of explication. Finally, I discuss the role that frameworks and the I/e distinction play in ESO, showing that ESO provides no reason to attribute the doctrine of ontological pluralism to Carnap. (shrink)

Verificationism has had a bad press for many years. The view that the meaning of our words is bound up with the discernible difference it would make if what we say, think or write were true or false, nowadays is scorned as “positivist” though it was shared by eminent empiricists and pragmatists. This paper seeks to sort through some of the complexities of what is often portrayed as an unduly simplistic conception. I begin with an overview of its main logical (...) empiricist varieties before considering which aspects of it fall victim to which of the three major types of objection that have been raised against it. I will conclude that what is left standing is a modest proposal that seems worth further investigation. (shrink)

This paper has three interdependent aims. The first is to make Reichenbach’s views on induction and probabilities clearer, especially as they pertain to his pragmatic justification of induction. The second aim is to show how his view of pragmatic justification arises out of his commitment to extensional empiricism and moots the possibility of a non-pragmatic justification of induction. Finally, and most importantly, a formal decision-theoretic account of Reichenbach’s pragmatic justification is offered in terms both of the minimax principle and the (...) dominance principle.

This paper reflects on metametaphysics and as such develops a metametameta-physical view: that quietist metametaphysics requires dialetheism, and in turn a paraconsistent logic. I demonstrate this using Carnap’s metametaphysical position in his 'Empiricism, Semantics and Ontology' as an example, with regard to how it exhibits self-reference and results in inconsistency. I show how applying Carnap’s position to itself produces a dilemma, both horns of which lead to a contradiction. Such inconsistency commonly arises from meta-theories with global scope, as the 'meta' (...) approach aims to transcend the scope of that which it is theorizing about, whilst the global nature will place itself back within the scope of that which it is theorizing about, which together result in the theory referring to itself whilst refuting itself. I argue that any global metametaphysical theory that draws a limit to thought will face self-reference problems leading to contradictory realms. My conclusion is conditional: If we want to meta-philosophize in such a way and treat quietist meta-theories as being true, then we need to be dialetheist and utilize a paraconsistent logic in order to accommodate the contradictions that result from such theorizing.

Many who take a dismissive attitude towards metaphysics trace their view back to Carnap’s ‘Empiricism, Semantics and Ontology’. But the reason Carnap takes a dismissive attitude to metaphysics is a matter of controversy. I will argue that no reason is given in ‘Empiricism, Semantics and Ontology’, and this is because his reason for rejecting metaphysical debates was given in ‘Pseudo-Problems in Philosophy’. The argument there assumes verificationism, but I will argue that his argument survives the rejection of verificationism. The root (...) of his argument is the claim that metaphysical statements cannot be justified; the point is epistemic, not semantic. I will argue that this remains a powerful challenge to metaphysics that has yet to be adequately answered. (shrink)

This project investigates naturalized metaphysics as a recent trend in analytic metaphysics originating in the naturalist attitude of James Ladyman and Don Ross in their seminal work Everything must Go: Metaphysics Naturalized (2007). The primary focus, however, will be the more recent article “Neo-Positivist Metaphysics” (2012) by Alyssa Ney that originates in this tradition. The project will conclude that naturalized metaphysics is an unsuccessful attempt at an answer to the question ’how is metaphysics possible’. More precisely, the project will establish (...) that any answer to this question must instruct how to succeed at attempts at assertions about the Kantian thing in itself. This requirement is the result of an argument that no other conception of ’reality’ is robust enough to accommodate an ambitious metaphysics. Subsequently, it will be argued that naturalized metaphysics is conceived by its proponents as an attempt at such an answer, but that naturalized metaphysics does not provide the required instruction. This problem occurs because of Carnap’s challenge to metaphysics. Carnap observes that no assertion can be made outside a linguistic framework which has the consequence that metaphysical assertions must be about the conceptual conventions of the linguistic framework rather than the thing in itself. It is the view of Ney and the other proponents of naturalized metaphysics that metaphysics is possible as a naturalized metaphysics; a metaphysics that appropriately defers or yields to the findings of science. The project argues that this requirement does nothing to ensure that Carnap’s challenge is avoided. The challenge is equally significant to naturalized and non-naturalized metaphysics, so long as both require that successful attempts at metaphysics must be assertions about the thing in itself. -/- The project concludes that until or unless Carnap’s challenge is refuted, naturalized metaphysics remain impossible, just like the metaphysics it is supposed to replace.

Taking a cue from remarks Thomas Kuhn makes in 1990 about the historical turn in philosophy of science, I examine the history of history and philosophy of science within parts of the British philosophical context in the 1950s and early 1960s. During this time, ordinary language philosophy's influence was at its peak. I argue that the ordinary language philosophers' methodological recommendation to analyze actual linguistic practice influences several prominent criticisms of the deductive-nomological model of scientific explanation and that these criticisms (...) relate to the historical turn in philosophy of science. To show these connections, I primarily examine the work of Stephen Toulmin, who taught at Oxford from 1949 to 1954, and Michael Scriven, who completed a dissertation on explanation under Gilbert Ryle and R.B. Braithwaite in 1956. I also consider Mary Hesse's appeal to an ordinary language-influenced account of meaning in her account of the role of models and analogies in scientific reasoning, and W.H. Watson's Wittgensteinian philosophy of science, an early influence on Toulmin. I think there are two upshots to my historical sketch. First, it fills out details of the move away from logical positivism to more historical- and practice-focused philosophies of science. Second, questions about linguistic meaning and the proper targets and aims of philosophical analysis are part and parcel of the historical turn, as well as its reception. Looking at the philosophical background during which so-called linguistic philosophers also had a hand in bringing these questions to prominence helps us understand why. (shrink)

The story of the rise and fall of pragmatism is sometimes called the eclipse narrative. This paper addresses a specific version of this narrative that the logical empiricists arrived in North America in the 1930s and within 30 years had supplanted the pragmatists as the dominant philosophy there. Philosophers such as Alan Richardson and Cheryl Misak have challenged this view by emphasizing the similarities between these two movements. While both seem to admit that there is a distinction between the two (...) when it comes to values, I point out that the issue of values feeds into all aspects of pragmatist thinking, and so despite what seems on the surface to be agreements between the two movements, they were still quite different in all areas of their thinking. I challenge the degree of similarities by arguing that there were some sharp distinctions between the two movements, with the most important being the fact-value distinction and its impact on how each conceived of the term “practical.” I close by addressing how these distinctions should affect how we conceive of the eclipse narrative.

Despite influencing the social sciences since the 1930s, S. S. Stevens' "operationist" philosophy of science has yet to be adequately understood. I reconstruct Stevens' operationism from his early work and assess the influence of various views (logical positivism, behaviorism and the "operational viewpoint" of P. W. Bridgman, among others) on Stevens. Stevens' operationism emerges, on my reconstruction, as a naturalistic methodological directive aimed at agreement, founded in turn on the belief that agreement is constitutive of science, the scientific community, and (...) objectivity. Further, I show that operationism is historically and philosophically independent of the views mentioned above. (shrink)

This paper applies conceptual engineering to deal with four objections that have been levelled against operationalism in psychology. These objections are: operationalism leads to harmful proliferation of concepts, operationalism goes hand-in-hand with untenable antirealism, operationalism leads to arbitrariness in scientific concept formation, and operationalism is incompatible with the usual conception of scientific measurement. Relying on a formulation of three principles of conceptual engineering, I will argue that there is a useful form of operationalism that does not fall prey to these (...) four objections. (shrink)

Carnap’s lectures at the 1935 Paris Congress for the Unity of Science marked the beginning of his mature metaphilosophy. This paper considers what role remained for epistemology once it was “purified” of all psychological elements as Carnap there demanded. It is argued that while this did mean the end of traditional epistemology, room was found for nontraditional versions in the course of the further development of Carnap’s logic of science.

This dissertation consists of three parts. Part I is a defense of an artificial language methodology in philosophy and a historical and systematic defense of the logical empiricists' application of an artificial language methodology to scientific theories. These defenses provide a justification for the presumptions of a host of criteria of empirical significance, which I analyze, compare, and develop in part II. On the basis of this analysis, in part III I use a variety of criteria to evaluate the scientific (...) status of intelligent design, and further discuss confirmation, reduction, and concept formation.

It is well-known that the mature Foucault, while recognizing the influence of phenomenology on him during his youth, declared his anti-phenomenological position since his archeological breakthrough. This paper tries to argue and show that though phenomenology is an object of criticism of Foucault’s archaeology, it nonetheless plays a paradoxical and strategic role in the construction of the archaeological project. Though Foucault undertakes in The Birth of the Clinic a critical deconstruction of phenomenology as positivism, against the open anti-positivist declaration of (...) phenomenology itself, in the Archeology of Knowledge Foucault acknowledges that the opening of the space of archeology requires the practice of the “épochè of the épochè”, and in this sense archeology is a positivism too. That means also that archeology is possible only by the practice of the phenomenological operation of épochè in order to exit from phenomenology. This paradoxical and strategic usage of phenomenology in Foucault’s archeology is extended to his theory of discourse. For Foucault came to realize the limit of discursive practice: not only words signify but things signify too. If archeology wants to extend its domain of competence, it has to recur to description according to the way things show up themselves. This is nothing other than the basic methodological recommendation of phenomenology. Thus Foucault’s open declaration of his anti-phenomenological position is merely apparent, hiding his discrete paradoxical and strategic usage of the rich methodological resources of phenomenology.

James Conant, a proponent of the ‘New American Wittgenstein’, has argued that the standard inter- pretation of Wittgenstein is wholly mistaken in respect of Wittgenstein’s critique of metaphysics and the attendant conception of nonsense. The standard interpretation, Conant holds, misascribes to Wittgenstein Carnapian views on the illegitimacy of metaphysical utterances, on logical syntax and grammar, and on the nature of nonsense. Against this account, I argue that (i) Carnap is misrepresented; (ii) the so-called standard interpretation (in so far as I (...) have contributed to it) is misrepresented; (iii) Wittgenstein’s views, early and late, are misrepresented. I clarify Wittgen- stein’s conception of logical syntax and of the nonsense that results from transgressing it. (shrink)

In her paper “Neo-positivist metaphysics” (Philosophical Studies, 160(1), 53–78, 2012), Alyssa Ney promises a naturalized metaphysics that is acceptable even by positivists’ – and specifically Carnap’s – standards. This neo-positivist metaphysics takes its outset in the findings of our best science and relies on them to inform a metaphysics that can avoid the dependence on linguistic frameworks that is inherent to Carnapian deflationism. Neo-positivist metaphysics attempts to sidestep these problems by inheriting its semantic credentials directly from science itself. This paper (...) argues that such attempts are unsuccessful since science contains no resources with which to answer Carnap’s challenge either, and a science-based metaphysics is therefore just as vulnerable to Carnapian deflationism as traditional metaphysics. Consequently, neo-positivist metaphysics does not provide the promised metaphysics that can avoid Carnapian deflationism. While this conclusion focuses on Ney’s neo-positivist metaphysics, its scope includes any attempt to avoid Carnapian deflationism by a naturalized metaphysics that relies on strict deference to the findings of science. Substantial metaphysics – naturalized or not – is impossible unless or until Carnapian deflationism is refuted, and the resources for such a refutation cannot be found in naturalized metaphysics.

In biology the term “vitalism” is usually associated with Hans Driesch’s doctrine of the entelechy: entelechies were nonmaterial, bio-specific agents responsible for governing a few peculiar biological phenomena. Since vitalism defined as such violates metaphysical materialism, the received view refutes the doctrine of the entelechy as a metaphysical heresy. But in the early twentieth century, a different, non-metaphysical evaluation of vitalism was endorsed by some biologists and philosophers, which finally led to a logical refutation of the doctrine of the entelechy. (...) In this non-metaphysical evaluation, first, vitalism was not treated as a metaphysical heresy but a legitimate response to the inadequacy of mechanistic explanations in biology. Second, the refutation of vitalism was logically rather than metaphysically supported by contemporary biological knowledge. The entelechy was not a valid concept, because vitalists could neither formulate vital laws, nor offer convincing examples of experimental indeterminism. (shrink)

Philosophy is usually considered to be searching out the most general, and hence also the most necessary and the most eternal, truth; its central part, ontology, is often assumed to be fastening upon whatever might be "the form of the world". And because our world is the world as formed by the way we comprehend it and by the way we cope with it by means of our language, it is often assumed that its form must be brought out by (...) the analysis of the interrelations between the meanings of our words and our statements. This is why many philosophers, and analytic philosophers in particular, say that philosophy consists in the analysis of meaning. However, to maintain that philosophy is in this way interlocked with necessary truth and with meaning is no longer a simple matter. Both these concepts are being constantly challenged. Is there, after all, something like necessary truth (pace Quine) to be captured by philosophy? Can we still maintain that there is a meaning (pace not only Quine, but also Austin, Wittgenstein and other sceptics), which can constitute the subject to philosophical analyses? And if these concepts should become endangered species, then what about philosophy? (shrink)

In recent years, a revisionist process focused on logical positivism can be observed, particularly regarding Carnap’s work. In this paper, I argue against the interpretation that Kuhn’s The Structure of Scientific Revolutions having been published in the International Encyclopedia of Unified Science, co-edited by Carnap, is evidence of the revisionist idea that Carnap “would have found Structure philosophically congenial”. I claim that Kuhn’s book, from Carnap’s point of view, is not in philosophy of science but rather in history of science (...) (in the context of a sharp discovery–justification distinction). It could also explain the fact that, despite his sympathetic letters to Kuhn as editor, Carnap never refers to Kuhn’s book in his work in philosophy of science. (shrink)

Doing Worlds with Words throws light on the problem of meaning as the meeting point of linguistics, logic and philosophy, and critically assesses the possibilities and limitations of elucidating the nature of meaning by means of formal logic, model theory and model-theoretical semantics. The main thrust of the book is to show that it is misguided to understand model theory metaphysically and so to try to base formal semantics on something like formal metaphysics; rather, the book states that model theory (...) and similar tools of the analysis of language should be understood as capturing the semantically relevant, especially inferential, structure of language. From this vantage point, the reader gains a new light on many of the traditional concepts and problems of logic and philosophy of language, such as meaning, reference, truth and the nature of formal logic.

The title is meant to emphasize the immense loss of status I take logic to have undergone in recent decades, and to suggest something about its causes. The loss is most obvious in the context of higher education, where almost no post-secondary institutions now have effectual general requirements in standard formal logic, as that was easily understood thirty or more years ago. Courses in so-called 'critical thinking' are, with rare and noble exceptions, only a further illustration of the point, for (...) many of them, if not most, say nothing at all about logical form and formal logic, and proceed as if thought and discourse could be critically understood and appraised in total ignorance of their formal aspects.
