Suppose that one is at least a minimal realist about a given domain, in that one thinks that that domain contains truths that are not in any interesting sense of our own making. Given such an understanding, what can be said for and against the method of reflective equilibrium as a procedure for investigating the domain? One fact that lends this question some interest is that many philosophers do combine commitments to minimal realism and a reflective equilibrium methodology. Here, for (...) example, is David Lewis on philosophy: Our “intuitions” are simply opinions: our philosophical theories are the same. Some are commonsensical, some are sophisticated; some are particular; some general; some are more firmly held, some less. But they are all opinions, and a reasonable goal for a philosopher is to bring them into equilibrium. Our common task it to find out what equilibria there are that can withstand examination, but it remains for each of us to come to rest at one or another of them… Once the menu of well-worked out theories is before us, philosophy is a matter of opinion. Is that to say that there is no truth to be had? Or that the truth is of our own making, and different ones of us can make it differently? Not at all! If you say flatly that there is no god, and I say that there are countless gods but none of them are our worldmates, then it may be that neither of us is making any mistake of method. We may each be bringing our opinions to equilibrium in the most careful possible way, taking account of all the arguments, distinctions, and counterexamples. But one of us, at least, is making a mistake of fact. Which one is wrong depends on what there is (1983: x-xi). In addition to philosophy in general, the method of reflective equilibrium has also been endorsed as the appropriate procedure for investigating various other subject.. (shrink)

The given is the state of a mind in its primary engagement with the world. A satisfactory epistemology—one, it turns out, that is foundationalist and includes a naïve realist view of perception—requires a certain account of the given. Moreover, knowledge based on the given requires both a particular view of the world itself and a heterodox account of judgment. These admittedly controversial claims are supported by basic ontological considerations. I begin, then, with two contradictory views of the world per se (...) and the structure one experiences. I draw out the consequences of these two views for what intentionality is. The two views yield incompatible accounts of the given. The definitive spontaneity of the one account, and passivity of the other, can be understood in terms of the structure (or lack thereof) in the given. In defense of the claim that a structured given is not an apt epistemic basis, I examine an attempt to found an epistemology on such an account in light of the so-called myth of the given. I maintain that the given, if it is to provide some justification for taking the world to be a particular way, must be unstructured. To support this, I first discuss a significant problem with traditional foundationalism. I then argue that a satisfactory (foundationalist) epistemology requires the rejection of the orthodox propositional view of judgment in favor of a non-propositional, reistic view. (shrink)

The age-old question “What is truth?” is not an unambiguous one. There are at least two different meanings. In one sense, it is a semantic question about the meaning of the word “truth” and/or a metaphysical question about the nature of the property of truth, that is, how truth can be defined in terms of other notions, if it is definable at all. In another sense, it is an epistemological question about the criterion or test of truth, that is, how (...) we can recognize or accept (empirical) propositions as true. Ayer, in Language, Truth and Logic (LTL) and some other articles, tried to convince us that when we attempt to elucidate a theory of truth, we are only engaging in the epistemological project of finding the criterion of truth. This anti-semantical and anti-metaphysical view is based on Ayer’s (radical) deflationism about truth. In this chapter, I will argue that since Ayer did not accept that the criterion of truth is intimately related to the concept of truth, he can be seen as a deflationist about the nature of truth and as an advocate of a certain (Schlickian) kind of correspondence conception about the criterion of truth. His position would not be tenable if he had maintained what some of his contemporaries accepted, namely that there is a close connection between the two truth-theoretical tasks: the definitional and the criterial one.

A. J. Ayer’s Language, Truth, and Logic had been responsible for introducing the Vienna Circle’s ideas, developed within a Germanophone framework, to an Anglophone readership. Inevitably, this migration from one context to another resulted in the alteration of some of the concepts being transmitted. Such alterations have served to facilitate a number of false impressions of Logical Empiricism from which recent scholarship still tries to recover. In this paper, I will attempt to point to the ways in which LTL has (...) helped to foster the various mistaken stereotypes about Logical Empiricism which were combined into the received view. I will begin by examining Ayer’s all too brief presentation of an Anglocentric lineage for his ideas. This lineage, as we shall see, simply omits the major 19th century Germanophone influences on the rise of analytic philosophy. The Germanophone ideas he presents are selectively introduced into an Anglophone context, and directed towards various concerns that arose within that context. I will focus on the differences between Carnap’s version of the overcoming of metaphysics, and Ayer’s reconfiguration into what he calls the elimination of metaphysics. Having discussed the above, I will very briefly outline the consequences that Ayer’s radicalisation of the Vienna Circle’s doctrines had on the subsequent Anglophone reception of Logical Empiricism.

The question how to turn the principles implicitly governing the concept of truth into an explicit definition of the concept hence coalesced with the question how to get a finite grip on the infinity of T-sentences. Tarski's famous and ingenious move was to introduce a new concept, satisfaction, which could be, on the one hand, recursively defined, and which, on the other hand, straightforwardly yielded an explication of truth. A surprising 'by-product' of Tarski's effort to bring truth under control was (...) the breathtaking finding that truth is in a precisely defined sense ineffable, that no non trivial language can contain a truth-predicate which would be adequate for the very 4 language. This implied that truth proved itself to be strangely 'language-dependent': we can have a concept of truth-in-L for any language L, but we cannot have a concept of truth applicable to every language. In a sense, this means, as Quine put it, that truth belongs to "transcendental metaphysics", and Tarski's 'scientific' investigations seem to lead us back towards a surprising proximity of some more traditional philosophical views on truth. 3. TARSKI'S THEORY AS A PARADIGM So far Tarski himself. Subsequent philosophers then had to find out what his considerations of the concept of truth really mean and what are their consequences; and this now seems to be an almost interminable task.

Esta enciclopédia abrange, de uma forma introdutória mas desejavelmente rigorosa, uma diversidade de conceitos, temas, problemas, argumentos e teorias localizados numa área relativamente recente de estudos, os quais tem sido habitual qualificar como «estudos lógico-filosóficos». De uma forma apropriadamente genérica, e apesar de o território teórico abrangido ser extenso e de contornos por vezes difusos, podemos dizer que na área se investiga um conjunto de questões fundamentais acerca da natureza da linguagem, da mente, da cognição e do raciocínio humanos, bem (...) como questões acerca das conexões destes com a realidade não mental e extralinguística. A razão daquela qualificação é a seguinte: por um lado, a investigação em questão é qualificada como filosófica em virtude do elevado grau de generalidade e abstracção das questões examinadas (entre outras coisas); por outro, a investigação é qualificada como lógica em virtude de ser uma investigação logicamente disciplinada, no sentido de nela se fazer um uso intenso de conceitos, técnicas e métodos provenientes da disciplina de lógica. O agregado de tópicos que constitui a área de estudos lógico-filosóficos é já visível, pelo menos em parte, no Tractatus Logico-Philosophicus de Ludwig Wittgenstein, uma obra publicada em 1921. E uma boa maneira de ter uma ideia sinóptica do território disciplinar abrangido por esta enciclopédia, ou pelo menos de uma porção substancial dele, é extrair do Tractatus uma lista dos tópicos mais salientes aí discutidos; a lista incluirá certamente tópicos do seguinte género, muitos dos quais se podem encontrar ao longo desta enciclopédia: factos e estados de coisas; objectos; representação; crenças e estados mentais; pensamentos; a proposição; nomes próprios; valores de verdade e bivalência; quantificação; funções de verdade; verdade lógica; identidade; tautologia; o raciocínio matemático; a natureza da inferência; o cepticismo e o solipsismo; a indução; as constantes lógicas; a negação; a forma lógica; as leis da ciência; o número.

Some members of the Vienna Circle argued for a coherence theory of truth. Their coherentism is immune to standard objections. Most versions of coherentism are unable to show why a sentence cannot be true even though it fails to cohere with a system of beliefs. That is, it seems that truth may transcend what we can be warranted in believing. If so, truth cannot consist in coherence with a system of beliefs. The Vienna Circle's coherentists held, first, that sentences are (...) warranted by coherence with a system of beliefs. Next they drew upon their verification theory of meaning, a consequence of which is that truth cannot transcend what can be warranted. The coherence theory of knowledge and verificationism together entail that truth cannot transcend what can be warranted by coherence with a system of beliefs. The Vienna Circle's argument for coherentism is strong and anticipates contemporary anti-realism. (shrink)

Correspondence theories are frequently either too vaguely expressed – “true statements correspond to the way things are in the world,” or implausible – “true statements mirror raw, mind-independent reality.” I address this problem by developing features and roles that ought to characterize what I call ldquo;modest” correspondence theories. Of special importance is the role of correspondence in directing our responses to cases of suspected non-factuality; lack of straightforward correspondence shows the need for, and guides us in our choice of, various (...) kinds of reconstrual projects. This, I argue, is in contrast to the approaches suggested by deflationism and coherence, and thus modest correspondence theories are appropriately distinct from rivals. (shrink)

Traces of the coherence theory are to be found in rationalistic epistemological systems of Leibniz, Spinoza, Kant, Hegel and Fichte. However, the first fully advanced coherence theory was proposed by Bradley in XIX century. He was followed by Joachim, McTaggart, and particularly Blanshard and Ewing. The coherence theory later became popular among philosophers of the Vienna Circle, notably in Neurath and Hempel.2 Recently, Rescher tried to combine various proposals of coherentists into one fully unified view.

: This paper explicates and defends the thesis that individual rational judgment, of the kind required for justification, whether in cognition or in morals, is fundamentally socially and historically conditioned. This puts paid to the traditional distinction, still influential today, between ‘rational’ and ‘historical’ knowledge. The present analysis highlights and defends key themes from Kant’s and Hegel’s accounts of rational judgment and justification, including four fundamental features of the ‘autonomy’ of rational judgment and one key point of Hegel’s account of (...) ‘mutual recognition’. These themes are linked to Kant’s and Hegel’s transformation of the modern natural law tradition. The results explain why Kant’s and Hegel’s philosophy are indeed the origins of the properly pragmatic account of rationality, why the pragmatic account of rationality provides genuine rational justification and why this pragmatic account of rational justification is consistent with realism about the objects of empirical knowledge and with strict objectivity about moral norms. > Russian translation : Nelly Motroshilova, ed., К 200-летию выхода в свет «Феноменологии духа» Гегеля, 195–219. > Turkish translation : ‘Hegel’in Tinin Görüngübilimi’nde Karşihkh Onanma ve Ussal Gerekçelendirme’.

This article examines how Quine and Sellars develop informatively contrasting responses to a fundamental tension in Carnap’s semantics ca. 1950. Quine’s philosophy could well be styled ‘Essays in Radical Empiricism’; his assay of radical empiricism is invaluable for what it reveals about the inherent limits of empiricism. Careful examination shows that Quine’s criticism of Carnap’s semantics in ‘Two Dogmas of Empiricism’ fails, that at its core Quine’s semantics is for two key reasons incoherent and that his hallmark Thesis of Extensionalism (...) is untenable. The tension in Carnap’s semantics together with Quine’s exposure of the severe limits of radical empiricism illuminate central features of Sellars’s philosophy: the fully general form of the myth of givenness, together with Sellars’s alternative Kantian characterisation of understanding; the full significance of Carnap’s distinction between conceptual analysis and conceptual explication, and its important methodological implications; the specifically pragmatic character of Sellars’s realism; and Sellars’s methodological reasons for holding that philosophy must be systematic and that systematic philosophy must be deeply historically and textually informed. This paper thus re-examines this recent episode of philosophical history for its philosophical benefits and systematic insights. (shrink)

I examine the thesis that Otto Neurath anticipated the programme of naturalised epistemology already at the time of the Vienna Circle and consider the relation between Neurath's proposals and those of two contemporary theorists whose research programmes he would thus have broadly anticipated. The thesis is confirmed by reference to Neurath's own writings. The connection between Neurath's programme and the programmes of his two successors considered here, however, is found to be highly indirect in one case and nonexistent in the (...) other — despite their undeniable overlap.

Do the terms “logical positivism” and “logical empiricism” mark a philosophically real and significant distinction? There is, of course, no doubt that the first term designates the group of philosophers known as the Vienna Circle, headed by Moritz Schlick and including Rudolf Carnap, Herbert Feigl, Philipp Frank, Hans Hahn, Otto Neurath, Friedrich Waismann and others. What is debatable, however, is whether the name “logical positivism” correctly distinguishes their doctrines from related ones called “logical empiricism” that emerged from the Berlin Society (...) for Scientific Philosophy around Hans Reichenbach which included Walter Dubislav, Kurt Grelling, Kurt Lewin and a young Carl Gustav Hempel.1 The ..

Positivism has been used to establish a standard that Information Systems (IS) research must meet to be scientific. According to such positivistic beliefs in IS, scientific research should: 1) be generalizable, 2) focus on stable independent variables, 3) have certain ontological assumptions, and 4) use statistical or quantitative methods rather than qualitative methods. We argue that logical positivist philosophers required none of these. On the contrary, logical positivist philosophers regarded philosophizing in general and ontological considerations in particular as nonsense. Moreover, (...) the positivists’ preferred empirical research method was not a survey, but rather a qualitative observation recorded by field notes. In addition, positivist philosophers required neither statistical nor nonstatistical generalizability. At least some positivist philosophers also acknowledged the study of singular cases as being scientific. Many research orientations (e.g., single-setting research, examination of change, qualitative research) that are deemed “unscientific” by positivism in IS seem to be “scientific” (in principle) according to logical positivism. In turn, generally speaking, what has been justified as scientific by positivism in IS (e.g., requirements of statistical or nonstatistical generalizability, surveys, independent variables, ontological views) were either not required by logical positivists or were regarded as nonsensical by logical positivists. Furthermore, given that positivism is sometimes associated (or confused) with logical empiricism in IS, we also briefly discuss logical empiricism. Finally, realizing that certain influential, taken-forgranted assumptions that underlie IS research are unwarranted could have ground-breaking implications for future IS research. (shrink)

Doxastic distinctions help us define the basis and biases in belief–formation. Empirical and extra-empirical justification play an important role in determining doxastic distinctions. When we distinguish the different types of beliefs, we understand that there are basically three kinds of beliefs, namely, verifiable, falsifiable, and unfalsifiable beliefs. Empirical justification provides the basis for establishing the veracity of verifiable and falsifiable beliefs. Extra-empirical justification provides the basis for establishing the veracity of unfalsifiable or irrefutable beliefs. Verifiable or falsifiable beliefs that are (...) reductive require the mandatory acceptance of their truth. However, unfalsifiable beliefs which are non-reductive require the volitional acceptance of their truth. Because there is both empirical and extra-empirical justification in belief-formation, we can accept beliefs with or without, against, or regardless of empirical evidence. Unfalsifiable beliefs do not mean that these beliefs are unjustifiable; it simply means that these beliefs are not empirically justifiable. Understanding the basis and biases of belief-formation is to be aware of how we come to know what we believe. As empirical basis allows us to hold beliefs based on either the principle of confirmation or falsification. Extra-empirical basis, namely phenomenological conjectures, allows us to hold beliefs founded on existential assertions. The intent of this paper is to present doxastic distinctions to help us understand the basis and biases associated with belief-formation. As long as epistemic claims are accepted, and their content is considered believable, the means used to arrive at those beliefs must also be respected. Every doxastic distinction not only provides the basis for belief-formation but also defines the role and limits of both empirical and extra-empirical justification in belief-formation. When we recognize the different types and different ways of justifying beliefs: we understand why we can accept beliefs with or without evidence; against or regardless of empirical justification, and know when to define beliefs as Plato argued as justified true belief and when to define beliefs as justified belief-decisions. Keywords: beliefs, justified true belief; justified belief-decisions, empirical and extra-empirical. (shrink)

The present article purports to show that the protocol sentence debate, pursued by some leading members of the Vienna Circle in the mid-1930s, was essentially a controversy over the explanation and the real significance of the concept of truth. It is further shown that the fundamental issue underlying the discussions about the concept of truth was the relationship between form and content, as well as between logic/language and the world. R. Carnap was the philosopher who most explicitly and systematically attempted (...) to come to grips with this problem. It is shown that the form-content distinction pervades the three most important phases of Carnap's philosophical development: the structuralist (in Der logische Aufbau der Welt), the syntactical and the semantical. His final semantical stance is essentially determined by the concept of linguistic frameworks. The article purports to demonstrate that this concept cannot be dispensed with in philosophy, but that Carnap failed to work out its ontological implications. Finally, the concept of an internal ontology is briefly delineated. (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.

This paper investigates the strange case of an argument that was directed against a positivist verification principle. We find an early occurrence of the argument in a talk by the phenomenologist Roman Ingarden at the 1934 International Congress of Philosophy in Prague, where Carnap and Neurath were present and contributed short rejoinders. We discuss the underlying presuppositons of the argument, and we evaluate whether the attempts by Carnap (especially) actually succeed in answering this argument. We think they don’t, and offer (...) instead a few sociological thoughts about why the argument seems to have disappeared from the profession’s evaluaton of the positivist criterion of verifiability.

Uebel has recently claimed that, contrary to popular opinion, none of the philosophers of the Vienna Circle of Logical Positivists were proponents of epistemological foundationalism. According to the considerations of the current discussion, however, Uebel's conclusion is erroneous, especially with respect to the work of Moritz Schlick. The chief reason Uebel offers to support his conclusion is that current attempts to portray Schlick's epistemology as foundationalist fail to overcome its ‘ultimate incoherence’. In contrast, it is argued that current interpretations, based (...) on the unpublished as well as the published record, provide understandings of Schlick's foundationalist epistemology as not only coherent, but plausible. In closing, Uebel's own treatment of Schlick's work, which purports to show that the most feasible candidates for foundational statements are ‘meaning-theoretic’ clarifications of the content of expressions, itself fails to accurately represent Schlick's own characterizations, and pictures Schlick's epistemology as a confused mix of epistemic and semantic insights.

In this paper, I argue (a) that the predicate "true" is ambiguously used to express a deflationary and a substantial concept of truth and (b) that the two concepts are systematically related in that substantial truths are deflationary truths of a certain kind. Claim (a) allows one to accept the main insights of deflationism but still take seriously, and participate in, the traditional debate about the nature of truth. Claim (b) is a contribution to that debate. The overall position is (...) not new and it has previously been defended by supervaluationists about vagueness. However, the position is here motivated in a new, independent way, and an explanation is offered why some uses of "true" do not seem to require disambiguation. (shrink)

Kurt Gödel criticizes Rudolf Carnap's conventionalism on the grounds that it relies on an empiricist admissibility condition, which, if applied, runs afoul of his second incompleteness theorem. Thomas Ricketts and Michael Friedman respond to Gödel's critique by denying that Carnap is committed to Gödel's admissibility criterion; in effect, they are denying that Carnap is committed to any empirical constraint in the application of his principle of tolerance. I argue in response that Carnap is indeed committed to an empirical requirement vis‐à‐vis (...) tolerance, a fact that becomes clear upon closer scrutiny of Carnap's relevant writings. *Received July 2009; revised January 2010. †To contact the author, please write to: Department of Philosophy, University of Saskatchewan, 9 Campus Drive, Saskatoon, SK S7N 5A5, Canada; e‐mail: [email protected].

This paper formally explores the common ground between mild versions of epistemological coherentism and infinitism; it proposes—and argues for—a hybrid, coherentist–infinitist account of epistemic justification. First, the epistemological regress argument and its relation to the classical taxonomy regarding epistemic justification—of foundationalism, infinitism and coherentism—is reviewed. We then recall recent results proving that an influential argument against infinite regresses of justification, which alleges their incoherence on account of probabilistic inconsistency, cannot be maintained. Furthermore, we prove that the Principle of Inferential Justification (...) has rather unwelcome consequences—formally resembling the Sorites paradox—as soon as it is iterated and combined with a natural Bayesian perspective on probabilistic inferences. We conclude that strong versions of foundationalism and infinitism should be abandoned. Positively, we provide a rough sketch for a graded formal coherence notion, according to which infinite regresses of epistemic justification will often have more than a minimal degree of coherence.

Coherence and correspondence are classical contenders as theories of truth. In this paper we examine them instead as interacting factors in the dynamics of belief across epistemic networks. We construct an agent-based model of network contact in which agents are characterized not in terms of single beliefs but in terms of internal belief suites. Individuals update elements of their belief suites on input from other agents in order both to maximize internal belief coherence and to incorporate ‘trickled in’ elements of (...) truth as correspondence. Results, though often intuitive, prove more complex than in simpler models (Hegselmann & Krause 2002, 2006; Grim, Singer, Reade & Fisher 2015). The optimistic finding is that pressures toward internal coherence can exploit and expand on small elements of truth as correspondence is introduced into epistemic networks. Less optimistic results show that pressures for coherence can also work directly against the incorporation of truth, particularly when coherence is established first and new data is introduced later.

In the Tractatus, Wittgenstein maintains that “The world is all that is the case.” Some philosophers have seen an advantage in introducing into a formal language either a constant which will represent the world, or an operator, e.g., ‘Max’, such that indicates that p gives a complete description of the actual world, of the world at some instant of time, or of a possible world. Such propositions are called world propositions, possible world propositions, or maximal propositions. For us, a maximal (...) proposition is a possible world proposition; it gives a complete description of one way the world might be. A maximal proposition p is not logically false, and for any proposition q, either p entails q or p entails not-q. (shrink)

A perennial epistemological question is whether things can be known just as they are in the absence of any awareness of them. This epistemological question is posterior to ontological considerations and more specific ones pertaining to mind. In light of such considerations, the author propounds a naïve realist, foundationalist account of knowledge of things in themselves, one that makes crucial use of the work of Brentano. After introducing the resources provided by Brentano’s study of mind, the author reveals the ontological (...) framework in which it takes place. Doing so is instrumental to illuminating acquaintance, the state that enables the direct engagement of a mind and some other thing. The author discusses this state and shows how it has the epistemic heft, with a Brentanian account of judgment, to provide the foundations of one’s knowledge of the world. A naïve realist, foundationalist account of knowledge is open to a compelling objection; the author presents this objection with the means of undermining it. In conclusion, the author recurs to the opening theme of the primacy of ontology and suggests that familiar misgivings about knowing things in themselves are all based on questionable—and ultimately untenable—ontological presuppositions.

John Dewey’s theory of truth is widely viewed as proposing to substitute “warranted assertibility” for “truth,” a proposal that has faced serious objections since the late 1930s. By examining Dewey’s theory in its historical context – and, in particular, by drawing parallels with Otto Neurath’s concurrent attempts to develop a non-correspondence, non-formal theory of truth – I aim to shed light on Dewey’s underlying objectives. Dewey and Neurath were well-known to each other and, as their writing and correspondence make clear, (...) they took similar paths over the mid-century philosophical terrain. I conclude that Dewey’s account of truth is more principled, and more relevant to historical debates, than it first appears. (shrink)

Truth is a fundamental philosophical concept that, despite its common and everyday use, has resisted common-sense formulations. At this point, one may legitimately wonder if there even is a common-sense notion of truth or what it could look like. In response, I propose here a common-sense account of truth based on four “truisms” that set a baseline for how to go about building an account of truth. Drawing on both ordinary language philosophy and contemporary pragmatic approaches to truth, I defend (...) a pragmatic, common-sense theory of truth. The result is a theory that focuses the use and function of truth while also emphasizing its “subject-independence.”. (shrink)

Realism about the external world enjoys little philosophical support these days. I rectify this predicament by taking a relatively pragmatist line of thought to defend commonsense realism; I support commonsense realism through an interpretation and application of Donald Davidson’s notion of triangulation, the triangle composed of two communicators coordinating and correcting their responses with a shared causal stimulus. This argument is important because it has a crucial advantage over the often used abductive argument for realism. My argument avoids unwarranted conclusions, (...) whereas the abductive argument is “inflationary” because it reaches beyond the limits of evidence for its realist conclusion. To illustrate the problems of the abductive argument and motivate my Davidsonian approach, I take a brief look at the abductive argument for realism in Frederick Will’s work. (shrink)

Abstract This article examines the little-explored remarks on verification in Wittgenstein's notebooks during the period between 1930 and 1932. In these remarks, Wittgenstein connects a verificationist theory of meaning with the notion of logical multiplicity, understood as a space of possibilities: a proposition is verified by a fact if and only if the proposition and the fact have the same logical multiplicity. But while in his early philosophy logical multiplicities were analysed as an outcome of the formal properties of simple (...) objects and simple signs, Wittgenstein in the early 1930s connects the notion of logical multiplicity with the notion of ways of seeing. I will argue that the relevant ways of seeing are closely similar to seeing-as or aspect seeing. According to Wittgenstein's view in the early 1930s, logical multiplicities are part of our perceptual experience of propositions and facts. In this sense, the verification relation depends on how we experience propositions and facts as being surrounded by a logical space of possibilities. Strikingly, Wittgenstein's way of thinking about the verification relation offers solutions to a set of seemingly intractable problems connected with the versions of verificationism developed by members of the Vienna Circle.

I defend against criticism the following claims concening Thomas Kuhn: (i) there is a strong naturalist streak in The structure of scientific revolutions, whereby Kuhn used the results of a posteriori enquiry in addressing philosophical questions; (ii) as Kuhn's career as a philosopher of science developed he tended to drop the naturalistic elements and to replace them with more traditionally philosophical a prior approaches; (iii) at the same there is a significant residue of positivist thought in Kuhm, which Kuhn did (...) not recognise as such; (iv) the naturalist elements referred to in (i) are the most original and fruitful elements of Kuhn's thinking; (v) the positivistic elements referred to in (iii) vitiated his thought and acted as factors in preventing Kuhn from developing the naturalistic elemtns and from following the path taken by much subsequent philosophy of science. Preston presents an alternative reading of Kuhn which emphasizes the Wittgensteinian elements in Kuhn. I argue that this alternative view is, descriptively, poorly supported by the textual evidence and the facts of the history of philosophy of science in the twentieth century. I provide some defence of the naturalistic approach and related themes. (shrink)

One of the motivations for the researches leaded by the members of Vienna Circle with regard to the foundations of scientific language is found on Wittgenstein’s “Tractatus Logico-Philophicus”. Even though there are divergences about the legitimacy of this influence, thebook was, in effect, taken as a theoretical motivation for the structuring of scientific language, developed by logical empiricists. This paper will present the theories developed by members of Vienna Circle emphasizing the elements presents in Tractatusthat were taken, largely, as influence (...) over the “criterion of meaning” of a philosophical proposition adopted by logical empiricists in an attempt to set a foundation for knowledge.

We respond to Lee’s (forthcoming) commentary on our article “Demystifying the Influential IS Legends of Positivism” (Siponen & Tsohou [S&T], 2018). Lee offers four arguments against our analyses and conclusions in S&T (2018). First, because logical positivism (LP) has been discredited, he contends it cannot be used as a normative standard in IS. We clarify that our conclusions in S&T (2018) point to (1) the lack of justification for certain IS beliefs, and (2) a misunderstanding rather than legitimacy of LP (...) as a philosophy of science. Second, Lee argues that IS researchers characterizing positivism never said they were following the tenets of LP. We provide evidence to show some influential papers on positivism in IS research indicated they were indeed following LP. Third, Lee offers an alternative explanation for the emergence and nature of IS positivism. His explanation has merit, and it can be accommodated in S&T’s (2018) account of positivism in IS. Unfortunately, his explanation does not account for certain problems in the IS discipline’s use of positivism. In S&T (2018), we provide a plausible explanation for these problems. Finally, we discuss the implications of S&T’s (2018) findings for the need to better understand the philosophical assumptions underlying “IS positivism.” We also counter Lee’s arguments that our conclusions in S&T (2018) should not make a difference to the future of IS research.

Recently, Michael Friedman has claimed that virtually all the seeds of Hempel’s philosophical development trace back to his early encounter with the Vienna Circle (Friedman 2003, 94). As opposed, however, to Friedman’s view of the principal early influences on Hempel, we shall see that those formative influences originated rather with the Berlin Group. Hempel, it is true, spent the fall term of 1929 as a student at the University of Vienna, and, thanks to a letter of recommendation from Hans Reichenbach, (...) he even attended some sessions of the Vienna Circle. But he spent much less time in Vienna than in Berlin, where he studied under Reichenbach from 1926 till 1933 and wrote a dissertation on probability, Reichenbach’s specialty. Hempel also attended seminars conducted by Walter Dubislav, another member of the Berlin Group. (shrink)
