Scientific Language

Numerous societal issues, from climate change to pandemics, require public engagement with scientific research. Such engagement reveals challenges that can arise when experts communicate with laypeople. One of the most common frameworks for framing these communicative interactions is the deficit model of science communication, which holds that laypeople lack scientific knowledge and/or positive attitudes towards science, and that imparting knowledge will fill knowledge gaps, lead to desirable attitude/behavior changes, and increase trust in science. §1 introduces the deficit model in more (...) detail and shows that adhering to this model often fails to achieve its aims, which motivates the main question of this chapter: how can Ludwik Fleck’s theory of thinking collectives address the persistent problem of deficit approaches in science communication? I suggest that it can do so by exposing the deficit model’s implicit assumption of an expert-lay divide. Accordingly, §2 lays out Fleck’s theory and §3 contrasts it with contemporary debates about science communication. Following this descriptive work, §4 draws on Fleck’s ideas to make four concrete suggestions for further questioning the expert-lay divide. (shrink)

Krisen, heißt es manchmal, erfordern klare Ansagen: Bei Behauptungen wissen wir, woran wir sind. Vermutungen hingegen sind unklar und stehen der Übernahme von Ver­ant­wor­tung entgegen. In diesem Essay wird mit den Mitteln der Sprachphilosophie ge­zeigt, dass vermutende Sprechakte für die Krisenkommunikation in der Corona-Pandemie richtig und wichtig sind. Weder sind Vermutungen anfälliger für Unklarheit als andere Sprechakte noch sind sie besser dazu geeignet, Verantwortung abzuweisen. Im Gegen­teil: In einer Situation, die durch Unsicherheit geprägt ist, sind Vermutungen besonders wertvoll für das (...) Kommunizieren ungesicherter Hypothesen. (shrink)

Przed skomentowaniem książki, oferuję uwagi na temat Wittgenstein i Searle i logicznej struktury racjonalności. Eseje tutaj są w większości już opublikowane w ciągu ostatniej dekady (choć niektóre zostały zaktualizowane), wraz z jednym niepublikowanym elementem, i nic tutaj nie będzie zaskoczeniem dla tych, którzy nadążyli za jego pracą. Podobnie jak W, jest uważany za najlepszego filozofa standupu swoich czasów, a jego twórczość pisemna jest solidna jak skała i przełomowa w całym. Jednak jego brak podjęcia później W wystarczająco poważnie prowadzi do pewnych (...) błędów i zamieszania. Tylko kilka przykładów: na p7 dwukrotnie zauważa, że nasza pewność co do podstawowych faktów wynika z przytłaczającej wagi rozumu na poparcie naszych roszczeń, ale W pokazał definitywnie w "Na pewności", że nie ma możliwości wątpliwości co do prawdziwej tylko aksjomatycznej struktury naszego systemu 1 postrzegania, wspomnień i myśli, ponieważ sam w sobie jest podstawą do osądu i nie może być osądzony. W pierwszym zdaniu na p8 mówi nam, że pewność jest re prostu, ale tego rodzaju "pewność", którą moglibyśmy nazwać Certainty2, jest wynikiem rozszerzenia naszej aksjomatycznej i niepodróżnej pewności (Pewność1) poprzez doświadczenie i jest zupełnie inna, ponieważ jest propositional (prawda lub fałsz). Jest to oczywiście klasyczny przykład "walki z urzekaniem naszej inteligencji przez język", którą W wielokrotnie demonstrował. Jedno słowo- dwa (lub wiele) różnych zastosowań. Jego ostatni rozdział "Jedność propozycji" (wcześniej niepublikowane) również skorzystają znacznie z czytania W "Na pewność" lub dwóch książek DMS na OC (patrz moje recenzje), ponieważ jasno różnica między prawdziwymi tylko zdania opisujące S1 i prawdziwe lub fałszywe propozycje opisujące S2. To uderza mnie jako znacznie lepsze podejście do S biorąc S1 postrzegania jako propositional ponieważ tylko się T lub F po raz zaczyna myśleć o nich w S2. Jednak jego punkt, że propozycje pozwalają na oświadczenia rzeczywistej lub potencjalnej prawdy i fałszu, przeszłości i przyszłości i fantazji, a tym samym stanowić ogromny postęp w stosunku do społeczeństwa pre lub protolinguistic, jest przekonujący. Jak mówi: "Propozycja jest w ogóle czymś, co może określić warunek satysfakcji... i warunek satysfakcji... jest to, że tak i tak jest." Lub, trzeba dodać, że może być lub może być lub może być wyobrażane, że tak jest. -/- Ogólnie rzecz biorąc, PNC jest dobrym podsumowaniem wielu znaczących postępów w Wittgenstein wynikających z pół wieku pracy S, ale moim zdaniem, W nadal jest niezrównany, gdy uchwycić, co mówi. Idealnie, powinny być czytane razem: Searle dla jasnej prozy spójne i uogólnienia, zilustrowane perspicacious przykłady W i genialny aforyzmów. Gdybym był dużo młodszy, napisałbym książkę, która właśnie to robi. -/- Ci, którzy chcą kompleksowych, aktualnych ram dla ludzkich zachowań z nowoczesnego widoku dwóch systems, mogą zapoznać sięz moją książką "Logiczna struktura filozofii, psychologii, mind ijęzyka w Ludwig wittgenstein i John Searle' 2nd ed (2019).

L’humain produit des discours sur le monde : mythologies, religions, mysticismes, philosophies, science. La majorité de ses discours sont de nature transcendante. À la suite d’un clarification conceptuelle fondée sur les notions de réflexion et de discours général, la philosophie apparaît comme un dis- cours général transcendant parmi d’autres ; d’où l’échec de celle-ci à rendre compte du monde et de la science ; d’où la nécessité de disposer d’un discours général non transcendant, un discours général proprement scientifique, une métascience. (...) À la lumière des frontières ainsi redéfinies, il sera proposé de fonder la métascience sur une interprétation de l’oeuvre de Mario Bunge. Cette interprétation se fonde sur un ensemble de postulats généraux aux- quels Mario Bunge adhère et tenus pour acquis par les scientifiques. Il est proposé que soutenir un tel ensemble de postulats sans les problématiser à la manière des philosophes, fait en sorte que la pensée de Bunge ne relève plus de la philosophie. (shrink)

Summary Hans Albert's famous principle ‘Sollen impliziert Können’, which should bridge the two disparate domains of normative decisions and empirical informations is a constitutive one of the Popperian metaethical philosophy of social relations.

EI análisis de algunos programas lógicos y de algunos problemas ya tradicionales de la teoría de la computabilidad -como el problema de la correspondencia de Post-, permiten mostrar algunas claves para argumentar acerca de la posibilidad o imposibilidad de un ordenador omnisciente. Los programas logicos inductivos y alguno de sus resultados más prometedores, como Golem, sirven para valorar la posibilidad de un ordenador corno ayudante cualificado en la tarea de hacer ciencia. Ambas discusiones dan paso a una reflexión final sobre (...) el mecanicismo.The analysis ofsome logical programs and some traditional topics from the computability theory -as the Post Correspondence Problem-, enables us to illustrate some key points for discussing the possibility ofa computer as an omniscient entity. Inductive logical programs and some oftheir most promising representatives, such as Golem, are showed useful for evaluating the possibility ofa computer as a qualified support ofscientific activity. Both topics give rise to a concluding discussion around mechanism. (shrink)

Science and mathematics continually change in their tools, methods, and concepts. Many of these changes are not just modifications but progress---steps to be admired. But what constitutes progress? This dissertation addresses one central source of intellectual advancement in both disciplines: reformulating a problem-solving plan into a new, logically compatible one. For short, I call these cases of compatible problem-solving plans "reformulations." Two aspects of reformulations are puzzling. First, reformulating is often unnecessary. Given that we could already solve a problem using (...) an older formulation, what do we gain by reformulating? Second, some reformulations are genuinely trivial or insignificant. Merely replacing one symbol with another does not lead to intellectual progress. What distinguishes significant reformulations from trivial ones? According to what I call "conceptualism" (or "conceptual empiricism"), reformulations are intellectually significant when they provide a different plan for solving problems. Significant reformulations provide inferentially different routes to the same solution. In contrast, trivial reformulations provide exactly the same problem-solving plans, and hence they do not change our understanding. This answers the second question about what distinguishes trivial from significant reformulations. However, the first question remains: what makes a new way of solving an old problem valuable? Here, a bevy of practical considerations come to mind: one formulation might be faster, less complicated, or use more familiar concepts. According to "instrumentalism," these practical benefits are all there is to reformulating. Some reformulations are simply more instrumentally valuable for meeting the aims of science than others. At another extreme, "fundamentalism" contends that a reformulation is valuable when it provides a more fundamental description of reality. According to this view, some reformulations directly contribute to the metaphysical aim of carving reality at its joints. Conceptualism develops a middle ground between instrumentalism and fundamentalism, preserving their benefits without their costs. I argue that the epistemic value of significant reformulations does not reduce to either practical or metaphysical value. Reformulations are valuable because they are a constitutive part of problem-solving. Both science and mathematics aim at solving all possible problems within their respective domains. Meeting this aim requires being able to plan for any possible problem-solving context, and this requires reformulating. By reformulating, we clarify what we need to know to solve problems. Still, one might wonder whether the value of reformulations requires underlying differences in explanatory power. According to "explanationism," a reformulation is valuable only when it provides a better explanation. Explanationism stands as a rival middle ground position to my own. However, it faces numerous counterexamples. In many cases, two reformulations provide the same explanation while nonetheless providing different ways of understanding a phenomenon. Hence, reformulating can be valuable even when neither formulation is more explanatory. Methodologically, I draw on a variety of case studies to support my account of reformulation. These range from classical mechanics to quantum chemistry, along with examples from mathematics. Symmetry arguments provide a paradigmatic example: the mathematics of symmetry groups radically recasts quantum mechanics and quantum chemistry. Nevertheless, elementary approaches exist that eschew this additional mathematical apparatus, solving problems in a more tedious but less mathematically-demanding manner. Further examples include reformulations of quantum field theory, Arabic vs. Roman numerals, and Fermat's little theorem in number theory. In each case, my account identifies how reformulations change and improve our understanding of science and mathematics. (shrink)

W. V. Quine calls some general methods of science maxims: general defeasible principles that call on us to approximate, maximize, or minimize a state and that are interpreted and weighed in context-sensitive ways. On my reading, his empiricism asks us to maximize accepting overall theories empirically equivalent to ours but to minimize accepting sentences that both do not affect the empirical content of our overall theory and do not simplify our overall theory. His naturalism asks us to maximize accepting sentences (...) that are solely supported by standards that support our best current scientific theory. Drawing on the Quine archive at Houghton Library at Harvard, I support and apply these interpretations by investigating his rapidly evolving later work on empirical content and empirical equivalence, including some of his views on translation in this later work and his vacillation between what he calls the ecumenical and sectarian attitudes.

I offer an interpretation of Carnap and Quine’s views on cognitive significance and insignificance. The basic idea behind their views is as follows: to judge an expression is insignificant is to recommend it not be used in or explicated into languages used to express truth-valued judgments in inquiry; to judge an expression is significant is to recommend it be used in or explicated into such languages. These judgments are pragmatic judgments, made in light of purposes for language use in inquiry. (...) For Carnap at least, these pragmatic judgments are non-cognitive. This basic idea is only a roughly correct statement of their views. This is because the details of the scientific languages they recommend for inquiry are necessary to understand their views and the way they understand their own views. Even so, I offer two reasons to suggest that this basic idea is worthy of our consideration today. First, it provides a conception of significance that captures the natural thought that epistemological concerns can lead us to consider expressions to be insignificant without requiring an objectionable form of verificationism. Second, if we appeal also to Carnap and Quine’s pluralistic attitude toward explication, we can make a pragmatic judgment that an expression is insignificant while judging it to be significant on a distinct explication of significance fit for describing and explaining natural language.

The title of this monograph needs explanation. It certainly sounds too promising. A more adequate, though more cumbersome one, would read: the logical syntax and semantics of the language of empirical theories. The treatment of this subject in the present monograph needs further qualifications. It focusses on what is characteristic of empirical theories as opposed to others, viz. mathematical ones. Now the difference between these two kinds of theories lies evidently, not in their syntax, but semantics. This is why our (...) main concern here is going to be with the problem of interpretation of empirical theories. The fundamental problem here concerns the distinction between the empirical and the a priori elements inherent in any such theory. Accordingly, our final task must include an explication of concepts such as: meaning postulate, analytic, synthetic, empirically meaningful sentence, and others related to them. (shrink)

In this paper I will investigate the possibility of completing a Positivist style account of demarcation. One reason for pursuing this project is that standard criticisms of Positivism do not have the bite against the demarcation project that they are often assumed to have. To argue this will be the burden of the first part of this paper. The other reason is that new research in logic has provided machinery not available to the Positivists; machinery that shows promise for solving (...) some of the technical problems faced by Positivists' account of demarcation. To argue this will be the burden of the second part of this paper. (shrink)

Carnap suggests that philosophy can be construed as being engaged solely in conceptual engineering. I argue that since many results of the sciences can be construed as stemming from conceptual engineering as well, Carnap’s account of philosophy can be methodologically naturalistic. This is also how he conceived of his account. That the sciences can be construed as relying heavily on conceptual engineering is supported by empirical investigations into scientific methodology, but also by a number of conceptual considerations. I present a (...) new conceptual consideration that generalizes Carnap’s conditions of adequacy for analytic–synthetic distinctions and thus widens the realm in which conceptual engineering can be used to choose analytic sentences. I apply these generalized conditions of adequacy to a recent analysis of scientific theories and defend the relevance of the analytic–synthetic distinction against criticisms by Quine, Demopoulos, and Papineau.

Criteria of empirical significance are supposed to state conditions under which reference to an unobservable object or property is “empirically meaningful”. The intended kind of empirical meaningfulness should be necessary for admissibility into the selective contexts of scientific inquiry. I defend Justus’s recent argument that the reasons generally given for rejecting the project of defining a significance criterion are unpersuasive. However, as I show, this project remains wedded to an overly narrow conception of its subject matter. Even the most cutting (...) edge significance criteria identify empirical significance with predictive power, and thereby rule out vocabulary with legitimate scientific functions. In a nutshell, the problem is that there are terms that reduce the computational burden of extracting predictions from theory, and that may therefore be scientifically useful, but that do not produce any additional predictions, and so are ruled scientifically inadmissibility by existing significance criteria. I spell out this objection by specifying terms of this kind that are ruled inadmissible by Creath’s and Schurz’s criteria. Having objected in this way to extant criteria, and to the equation of empirical significance with predictive power in general, I discuss an approach to defining empirical significance that is capable of avoiding my objection and, more ambitiously, that may break the cycle of “punctures and patches” that has plagued the project from the beginning: I gloss Goldfarb and Ricketts’s idea of “case-by-case” delineations of empirically significant terms as the provision of special rather than general explications of the informal concept of empirical significance.

That some propositions are testable, while others are not, was a fundamental idea in the philosophical program known as logical empiricism. That program is now widely thought to be defunct. Quine’s (1953) “Two Dogmas of Empiricism” and Hempel’s (1950) “Problems and Changes in the Empiricist Criterion of Meaning” are among its most notable epitaphs. Yet, as we know from Mark Twain’s comment on an obituary that he once had the pleasure of reading about himself, the report of a death can (...) be an exaggeration. The research program that began in Vienna and Berlin continues, even though many of the specific formulations that came out of those circles are flawed and need to be replaced. (shrink)

Carnap’s search for a criterion of empirical significance is usually considered a failure. I argue that the results from two out of his three different approaches are at the very least problematic, but that one approach led to success. Carnap’s criterion of translatability into logical syntax is too vague to allow for definite results. His criteria for terms—introducibility by chains of reduction sentences and his criterion from “The Methodological Character of Theoretical Concepts”—are almost trivial and have no clear relation to (...) the empirical significance of sentences. However, his criteria for sentences—translatability, verifiability, falsifiability, confirmability—are usable, and under the assumptions needed for the Carnap sentence approach, verifiability, falsifiability, and translatability become equivalent. As a result of the Carnap sentence approach, metaphysics is rendered analytic. (shrink)

"Testability and Meaning" is one of Carnap's best-known works. It has been usually seen as one of the main sources of the received view of the philosophy of science, and it is normally read in the hght of the tradition it originated. Nevertheless, this reading detaches the text from the philosophical project to which it belongs. This paper aims to situate Camap's article in its proper philosophical place, which is found in the programme initiated in the Logische Syntax, a programme (...) which essentially remained alive throughout the rest of Camap's career. The paper shows how this view opens up a natural way of understanding Carnap's important article in a different light, more interesting and coherent. (shrink)

This article considers the development of Philipp Frank’s opposition to metaphysics in the light of the contention that there also was a long-standing pragmatic strand to the theorizing about science in the Vienna Circle. It is argued that the later Frank did not only distinguish metaphysical statements from those deemed simply cognitively meaningless by a substantive criterion but that in order to identify the latter he also sought to employ a practical rather than a formal criterion with which he and (...) Neurath had long been acquainted. (shrink)

Carnap’s analysis of the language of science had presupposed too close a connection between the semantics and testability. The core problem of the logical empiricist tradition was to show how to provide the interpretation of theoretical terms and hence the explanation of their application to observable entities by means of observation terms. It is argued that the utilization of a much more expressive semantic theory which identifies meanings with hyperintensional entities leads to a clarification of the competencies of semantics and (...) methodology. It is claimed that the observability or unobservability of term’s referents does not determine the meaning of the term. Carnap’s reduction sentences are therefore conceived only as methodological devices for the determination of unobservables via the theory-presupposed observable aspects. (shrink)

Recent scholarship (by mainly Michael Friedman, but also by Thomas Uebel) on the philosophy of Rudolf Carnap covering the period from the publication of Carnap’s’ 1928 book Der Logische Aufbau der Welt through to the mid to late 1930’s has tended to view Carnap as espousing a form of conventionalism (epitomized by his adoption of the principle of tolerance) and not a form of empirical foundationalism. On this view, it follows that Carnap’s 1934 The Logical Syntax of Language is the (...) pinnacle of his work during this era, this book having developed in its most complete form the conventionalist approach to dissolving the pseudoproblems that often attend philosophical investigation. My task in this paper, in opposition to this trend, is to resuscitate the empiricist interpretation of Carnap’s work during this time period. The crux of my argument is that Carnap’s 1934 book, by eschewing for the most part the empiricism he espouses in the Aufbau and in his 1932 The Unity of Science, is led to a form of conventionalism that faces the serious hazard of collapsing into epistemological relativism. My speculation is that Carnap came to recognize this deficiency in his 1934 book, and in subsequent work (“Testability and Meaning”, published in 1936/37) felt the need to re-instate his empiricist agenda. This subsequent work provides a much improved empiricist epistemology from Carnap’s previous efforts and, ashistory informs us, sets the standard for future research in the theory of confirmation. (shrink)

The first theory of confirmation that Carnap developed in detail is to be found in "Testability and Meaning". In this paper, he addressed the issue of a definition of empiricism, several years after abandoning the quest for a unique and universal logical framework supposed to be the basis of a clear distinction between the meaningful sentences of science and the pseudo-sentences of metaphysics. The principle of tolerance (according to which everyone is free to build up his own form of language (...) as he wishes) had been adopted near the end of 1932, at a time when it was already obvious to Carnap that a strictly verificationist criterion of meaning was inadequate. He therefore considered a variety of empiricisms and a variety of choices for the language of science. As Carnap put it, "there are many different possibilities in framing an empiricist language" and, correspondingly, several degrees of liberalization of the criterion of meaning. It was in this context that Carnap provided both a logical (syntactical) and an empirical analysis of confirmation (and of testing), before distinguishing requirements of different strengths which served the purpose of defining several versions of empiricism. (shrink)

The sheer multitude of criteria of empirical significance has been taken as evidence that the pre-analytic notion being explicated is too vague to be useful. I show instead that a significant number of these criteria—by Ayer, Popper, Przełęcki, Suppes, and David Lewis, among others—not only form a coherent whole, but also connect directly to the theory of definition, the notion of empirical content as explicated by Ramsey sentences, and the theory of measurement; two criteria by Carnap and Sober are trivial, (...) but can be saved and connected to the other criteria by slight modifications. A corollary is that the ordinary language defense of Lewis, the conceptual arguments by Ayer and Popper, the theoretical considerations by Przełęcki, and the practical considerations by Suppes all apply to the same criterion or closely related criteria. Furthermore, the equivalence of some criteria allows for their individual justifications to be taken cumulatively and, together with the entailment relations between nonequivalent criteria, suggest criteria for general auxiliary assumptions, comparative criteria, and more liberal conceptions of observation. (shrink)

The purpose of this paper is to try to set the record a little straighter about the idea of a verifiability criterion.

Two chief problems of the theory of knowledge are the question of meaning and the question of verification. The first question asks under what conditions a sentence has meaning, in the sense of cognitive, factual meaning. The second one asks how we get to know something, how we can find out whether a given sentence is true or false. The second question presupposes the first one. Obviously we must understand a sentence, i.e. we must know its meaning, before we can (...) try to find out whether it is true or not. But, from the point of view of empiricism, there is a still closer connection between the two problems. In a certain sense, there is only one answer to the two questions. If we knew what it would be for a given sentence to be found true then we would know what its meaning is. And if for two sentences the conditions under which we would have to take them as true are the same, then they have the same meaning. Thus the meaning of a sentence is in a certain sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. (shrink)
