In the late 1930s, a few years before the start of the Second World War, a small number of European philosophers of science emigrated to the United States, escaping the increasingly perilous situation on the continent. Among the first expatriates were Rudolf Carnap and HansReichenbach, arguably the most influential logical empiricists of their time. In this two-part paper, I reconstruct Carnap’s and Reichenbach’s surprisingly numerous interactions with American academics in the decades before their move in order (...) to explain the impact of their arrival in the late 1930s. This second part traces Reichenbach’s development and focuses on his frequent interactions with American academics throughout the 1930s. I show that Reichenbach was quite ignorant about developments in Anglophone philosophy in the first stages of his career but became increasingly focused on the United States from the late 1920s onwards. I reconstruct Reichenbach’s efforts to find a job across the Atlantic and show that some of his English publications—most notably Experience and Prediction—were attempts to change the American narrative about logical empiricism. Whereas U. S. philosophers identified scientific philosophy with the views of the Vienna Circle, Reichenbach aimed to market his probabilistic philosophy of science as a subtler alternative. (shrink)
I would like to assume that Reichenbach's distinction of Justification and Discovery lives on, and to seek arguments in his texts that would justify their relevance in this field. The persuasive force of these arguments transcends the contingent circumstances apart from which their genesis and local transmission cannot be made understandable. I shall begin by characterizing the context distinction as employed by Reichenbach in "Experience and Prediction" to differentiate between epistemology and science (1). Following Thomas Nickles and Kevin (...) T. Kelly, one can distinguish two meanings of the context distinction in Reichenbach's work. One meaning, which is primarily to be found in the earlier writings, conceives of scientific discoveries as potential objects of epistemological justification. The other meaning, typical for the later writings, removes scientific discoveries from the possible domain of epistemology. The genesis of both meanings, which demonstrates the complexity of the relationships obtaining between epistemology and science, can be made understandable by appealing to the historical context (2). Both meanings present Reichenbach with the task of establishing the autonomy of epistemology through the justification of induction. Finally, I shall expound this justification and address some of its elements of rationality characterizing philosophy of science(3). (shrink)
First published in 1949 expressly to introduce logical positivism to English speakers. Reichenbach, with Rudolph Carnap, founded logical positivism, a form of epistemofogy that privileged scientific over metaphysical truths.
HansReichenbach’s pragmatic treatment of the problem of induction in his later works on inductive inference was, and still is, of great interest. However, it has been dismissed as a pseudo-solution and it has been regarded as problematically obscure. This is, in large part, due to the difficulty in understanding exactly what Reichenbach’s solution is supposed to amount to, especially as it appears to offer no response to the inductive skeptic. For entirely different reasons, the significance of (...) Bertrand Russell’s classic attempt to solve Hume’s problem is also both obscure and controversial. Russell accepted that Hume’s reasoning about induction was basically correct, but he argued that given the centrality of induction in our cognitive endeavors something must be wrong with Hume’s basic assumptions. What Russell effectively identified as Hume’s (and Reichenbach’s) failure was the commitment to a purely extensional empiricism. So, Russell’s solution to the problem of induction was to concede extensional empiricism and to accept that induction is grounded by accepting both a robust essentialism and a form of rationalism that allowed for a priori knowledge of universals. So, neither of those doctrines is without its critics. On the one hand, Reichenbach’s solution faces the charges of obscurity and of offering no response to the inductive skeptic. On the other hand, Russell’s solution looks to be objectionably ad hoc absent some non-controversial and independent argument that the universals that are necessary to ground the uniformity of nature actually exist and are knowable. This particular charge is especially likely to arise from those inclined towards purely extensional forms of empiricism. In this paper the significance of Reichenbach’s solution to the problem of induction will be made clearer via the comparison of these two historically important views about the problem of induction. The modest but important contention that will be made here is that the comparison of Reichenbach’s and Russell’s solutions calls attention to the opposition between extensional and intensional metaphysical presuppositions in the context of attempts to solve the problem of induction. It will be show that, in effect, what Reichenbach does is to establish an important epistemic limitation of extensional empiricism. So, it will be argued here that there is nothing really obscure about Reichenbach’s thoughts on induction at all. He was simply working out the limits of extensional empiricism with respect to inductive inference in opposition to the sort of metaphysics favored by Russell and like-minded thinkers. (shrink)
In the years before the Second World War, Rudolf Carnap and HansReichenbach emigrated to the United States, escaping the quickly deteriorating political situation on the continent. Once in the U. S., the two significantly changed the American philosophical climate. This two-part paper reconstructs Carnap’s and Reichenbach’s surprisingly numerous interactions with American academics in the decades before their move in order to explain the impact of their arrival in the late 1930s. Building on archival material of several (...) key players and institutions, I take some first steps toward answering the question why logical empiricism became so successful in the United States after the War. This first part reconstructs Carnap’s development between 1923, when he first visited New York, and 1936, when he was offered a position at the University of Chicago. I describe Carnap’s first substantive contacts with American philosophers as well as the events leading up to his decision to emigrate. In addition, I argue that some of Carnap’s work from the mid-1930s—in particular “Testability and Meaning”—can be better understood if we take into account his attempts to correct the American narrative about logical positivism and his increasingly desperate efforts to find a position in the United States.

ABSTRACTThe distinction between ‘context of discovery’ and ‘context of justification’ in philosophy of science appears simple at first but contains interesting complexities. Paul Hoyningen-Huene has catalogued some of these complexities and suggested that the core usefulness of the ‘context distinction’ is in distinguishing between descriptive and normative perspectives. Here, I expand on Hoyningen-Huene’s project by tracing the label ‘context of discovery and context of justification’ to its origin. I argue that, contrary to initial appearances, HansReichenbach’s initial context (...) distinction from 1938 does not easily map onto Hoyningen-Huene’s distinction between descriptive and normative perspectives on science. However, this is not a reason to reject Hoyningen-Huene’s simplified context distinction, nor do I recommend returning to Reichenbach’s initial proposal. It is, however, further reason to believe that the context distinction does not have a single, easily understood meaning. Along the way, I revisit Reichenbach’s version of ‘rational reconstruction’ and highlight its usefulness as a tool for philosophy in general. (shrink)
With his distinction between the "context of discovery" and the "context of justification", HansReichenbach gave the traditional difference between genesis and validity a modern standard formulation. Reichenbach's distinction is one of the well-known ways in which the expression "context" is used in the theory of science. My argument is that Reichenbach's concept is unsuitable and leads to contradictions in the semantic fields of genesis and validity. I would like to demonstrate this by examining the different (...) meanings of Reichenbach's context distinction. My investigation also shows how the difference between genesis and validity precedes Reichenbach's context distinction and indicates approaches for meaningful applications of the concept of context to the phenomena designated by Reichenbach. I will begin by reconstructing the way in which Reichenbach introduces the distinction between discovery and justification as a difference of contexts (I). Drawing on the numerous meanings of the term "context", I will then emphasize some chief characteristics and review, through exemplification, the usage of this term. First of all, I turn to the context of discovery as the nonrational part of all scientific knowledge and show that this meaning cannot be defined consistently (la). For the context of justification, one can distinguish two main cases: the context of justification is either contrasted with the context of discovery, or it forms a unit there with. In the first case, the use of the context term becomes paradoxical, insofar as justification separated from scientific practice does not represent a field of reference which could be specifically contrasted with another field of reference (I b). In the second case, the unifying definitions contradict the contextual meaning of discovery and justification (1 c). In the last section, I point to a useful application of the concept of context which can be found in Reichenbach's argumentation and which refers to the practical conditions of justification(2).

In "The Logical Form of Action Sentences" Donald Davidson argues that HansReichenbach's analysis of action and event sentences is "radically defective." I show that Reichenbach can easily deflect Davidson's objections, thus leaving their respective accounts largely comparable.
Confronted with the problem of induction, HansReichenbach accepts that we cannot justify that induction is reliable. He tries to solve the problem by proving a weaker proposition: that induction is an optimal method of prediction, because it is guaranteed not to be worse and may be better than any alternative. Regarding the most serious objection to his approach, Reichenbach himself hints at an answer without spelling it out. In this paper, I will argue that there are (...) two workable strategies to rehabilitate Reichenbach’s account. The first leads to the widely discussed method of meta-induction, as proposed by Gerhard Schurz. The second strategy has not been suggested thus far. I will develop the second strategy and argue for it being, in some respects, superior to the first and closer to Reichenbach’s own position. (shrink)
The distinction between the contexts of discovery and justification, this distinction dear to the projects of logical empiricism, was, as is well known, introduced in precisely those terms by HansReichenbach in his Experience and Prediction (Reichenbach 1938). Thus, while the idea behind the distinction has a long history before Reichenbach, this text from 1938 plays a salient role in how the distinction became canonical in the work of philosophers of science in the mid twentieth century. (...) The new contextualist history of philosophy that has arisen in recent years invites us into an investigation of the nuances of philosophical distinctions and their roles in shaping the development of disciplines. Logical empiricism played a key role in the historical development of philosophy of science and this contextualist history has revealed a much richer set of projects in logical empiricism than the potted histories had allowed. Many stories have been told about the contexts of justification and discovery; few of those stories have paid more than passing attention to the larger projects in epistemology and meta-epistemology that Reichenbach was pursuing when he drew the distinction. This brief essay will seek partially to rectify that lack in, I hope, a somewhat surprising way. I shall stress the connection between this canonical distinction and some other epistemological and social terms that loom large in Reichenbach’s text, arguing that the social relevance of scientific philosophy for Reichenbach cannot be set aside in understanding his use of the DJ distinction. My point is, therefore, historical and reflexive. If we attend to the larger significance of the project in scientific philosophy that Reichenbach was advancing, we can see more clearly why the DJ distinction was introduced and rethink the significance of questioning the distinction.

Ernest Nagel played a key role in bridging the gap between American philosophy and logical empiricism. He introduced European philosophy of science to the American philosophical community but also remained faithful to the naturalism of his teachers. This paper aims to shed new light on Nagel’s intermediating endeavors by reconstructing his philosophical development in the late 1920s and 1930s. This is a decisive period in Nagel’s career because it is the phase in which he first formulated the principles of his (...) naturalism and spent a year in Europe to visit the key centers of logical empiricism. Building on a range of published and unpublished papers, notes, and correspondence—including hundreds of pages of letters to his close friend Sidney Hook—I reconstruct Nagel’s philosophical development, focusing especially on the philosophical influence of John Dewey, Morris R. Cohen, Rudolf Carnap, and HansReichenbach. (shrink)
Die Berliner Gruppe um HansReichenbach, Kurt Lewin, Walter Dubislav, Alexander Herzberg, Kurt Grelling und Carl Gustav Hempel, die die »Gesellschaft für wissenschaftliche Philosophie« in Berlin leitete, verstand sich als gleichberechtigter Partner der Wiener Kollegen und schlug durchaus einen eigenständigen Weg zu »einer an der exakten Wissenschaft geschulten Philosophie« (Reichenbach) ein. Im öffentlichen und geistigen Leben der deutschen Hauptstadt spielte sie eine bedeutende Rolle, bevor ihre Mitglieder durch den Nationalsozialismus ins Exil gezwungen wurden. Nach ihrer Emigration haben (...)Reichenbach, Hempel und andere für die Entwicklung der analytischen Philosophie und der modernen Wissenschaftstheorie im angelsächsischen Sprachraum eine bedeutende Rolle gespielt.

In what sense is the direction of time a matter of convention? In 'The Direction of Time', HansReichenbach makes brief reference to parallels between his views about the status of time’s direction and his conventionalism about geometry. In this article, I: (1) provide a conventionalist account of time direction motivated by a number of Reichenbach’s claims in the book; (2) show how forwards and backwards time can give equivalent descriptions of the world despite the former being (...) the ‘natural’ direction of time; and (3) argue that this offers an important middle-ground position between existing realist and antirealist accounts of the direction of time.

Unsere These lautet, dass die Geschichte des logischen Empirismus bisher nicht in ihrer ganzen Komplexität dargestellt wurde. Es herrscht das Bild vor, dass vor allem der Wiener Kreis die wissenschaftliche Philosophie seiner Zeit dominiert habe. In Wirklichkeit waren HansReichenbach und die Philosophen und Wissenschaftler in seiner Gruppe mehr als nur geistige Verwandte der Wiener logischen Empiristen. Die Berliner Gruppe war ein gleichberechtigter Partner bei der Verbreitung wissenschaftlicher Philosophie im deutschsprachigen Raum um 1930 und schlug dabei durchaus einen (...) individuellen Weg ein. Reichenbach hat daher auch ausdrücklich die Eigenständigkeit der Berliner Gruppe innerhalb des logischen Empirismus verteidigt (Hoffmann 1994, 26). Dabei kämpfte er nicht einfach für Gleichberechtigung mit dem Wiener Kreis. Reichenbach beanspruchte sogar die Priorität der Initiative. (shrink)
This paper outlines the intellectual biography of Walter Dubislav. Besides being a leading member of the Berlin Group headed by HansReichenbach, Dubislav played a defining role as well in the Society for Empirical/Scientific Philosophy in Berlin. A student of David Hilbert, Dubislav applied the method of axiomatic to produce original work in logic and formalist philosophy of mathematics. He also introduced the elements of a formalist philosophy of science and addressed more general problems concerning the substantiation of (...) human knowledge. What set Dubislav apart from the other logical empiricists was his expertise in the history of logic and exact philosophy which enabled him to elucidate and advance the thinking in both disciplines. In the realm of logic proper, Dubislav is best known for his pioneering work in theory of definitions. What is more, he did original work on the so called ‘quasi truth-tables’ which aided Reichenbach in developing his logic of probability. Dubislav also elaborated an influe.. (shrink)
Walter Dubislav (1895–1937) was a leading member of the Berlin Group for scientific philosophy. This “sister group” of the more famous Vienna Circle emerged around HansReichenbach’s seminars at the University of Berlin in 1927 and 1928. Dubislav was to collaborate with Reichenbach, an association that eventuated in their conjointly conducting university colloquia. Dubislav produced original work in philosophy of mathematics, logic, and science, consequently following David Hilbert’s axiomatic method. This brought him to defend formalism in these (...) disciplines as well as to explore the problems of substantiating (Begründung) human knowledge. Dubislav also developed elements of general philosophy of science. Sadly, the political changes in Germany in 1933 proved ruinous to Dubislav. He published scarcely anything after Hitler came to power and in 1937 committed suicide under tragic circumstances. The intent here is to pass in review Dubislav’s philosophy of logic, mathematics, and science and so to shed light on some seminal yet hitherto largely neglected currents in the history of philosophy of science.

The Berlin Group for scientific philosophy was active between 1928 and 1933 and was closely related to the Vienna Circle. In 1930, the leaders of the two Groups, HansReichenbach and Rudolf Carnap, launched the journal Erkenntnis. However, between the Berlin Group and the Vienna Circle, there was not only close relatedness but also significant difference. Above all, while the Berlin Group explored philosophical problems of the actual practice of science, the Vienna Circle, closely following Wittgenstein, was more (...) interested in problems of the language of science. The book includes first discussion ever (in three chapters) on Walter Dubislav’s logic and philosophy. Two chapters are devoted to another author scarcely explored in English, Kurt Grelling, and another one to Paul Oppenheim who became an important figure in the philosophy of science in the USA in the 1940s–1960s. Finally, the book discusses the precursor of the Nord-German tradition of scientific philosophy, Jacob Friedrich Fries. Mehr anzeigen Weniger anzeigen . (shrink)
The aim of this paper is to show that a comprehensive account of the role of representations in science should reconsider some neglected theses of the classical philosophy of science proposed in the first decades of the 20th century. More precisely, it is argued that the accounts of Helmholtz and Hertz may be taken as prototypes of representational accounts in which structure preservation plays an essential role. Following Reichenbach, structure-preserving representations provide a useful device for formulating an up-to-date version (...) of a (relativized) Kantian a priori. An essential feature of modern scientific representations is their mathematical character. That is, representations can be conceived as (partially) structure-preserving maps or functions. This observation suggests an interesting but neglected perspective on the history and philosophy of this concept, namely, that structure-preserving representations are closely related to a priori elements of scientific knowledge. Reichenbach’s early theory of a relativized constitutive but non-apodictic a priori component of scientific knowledge provides a further elaboration of Kantian aspects of scientific representation. To cope with the dynamic aspects of the evolution of scientific knowledge, Cassirer proposed a re-interpretation of the concept of representation that conceived of a particular representation as only one phase in a continuous process determined by pragmatic considerations. Pragmatic aspects of representations are further elaborated in the classical account of C.I. Lewis and the more modern of Hasok Chang. (shrink)
In the late 1920s and early 1930s, the philosopher HansReichenbach led a group of like-minded colleagues in Berlin that must count as an independent point of origin of the movement of logical empiricism. Like the Vienna Circle with whom they cooperated on numerous occasions, their concern was to develop a philosophy of science adequate to the latest advances in science itself. Differences of philosophical background and interests, however, resulted in putting different accents by justifying scientific knowledge.
The received view has it that HansReichenbach and his friends of the Berlin Group worked close together with the more prominent Vienna Circle. In the wake of this view, Reichenbach was often treated as a logical positivist – despite the fact that he decisively opposed it. In this chapter we follow another thread. We shall show the “third man”– besides Reichenbach and Walter Dubislav – of the Berlin Group, Kurt Grelling, as a man who could (...) grasp the academic trends of the time faster than anybody else, who was better informed about logic and philosophy of nature than his two prominent colleagues and thus, could better delineate, although tentatively, central threads of research of the Berlin Group. Grelling did this on several occasions, but most ostensibly in the last years of his life when he was focused on problems of formal ontology. On the basis of this analysis, we shall see that in the early 1920s, Reichenbach too was led by a project in ontology of science that he elaborated together with the psychologist Kurt Lewin. Moreover, Reichenbach’s later philosophy of nature was also shaped by this project. We present this direction of philosophy of science as a “road less travelled” which, however, if revived, can point to a new direction that will more closely connect philosophy and science. (shrink)
Chapter 3 surveys objectivity in the natural sciences. Thomas Kuhn problematized the logicist understanding of the objectivity or rationality of scientific change, providing a very different picture than that of the cumulative or step-wise progress of theoretical science. Theories often compete, and when consensus builds around one competitor it may be for a variety of reasons other than just the direct logical implications of experimental successes and failures. Kuhn pitted the study of the actual history of science against what (...) class='Hi'>HansReichenbach referred to as the “logical substitutes” logicists used to reconstruct the rationality of theory change. Such substitutes were promoted to show that theory confirmation is a purely epistemic affair, where purely epistemic implies purely inferential. But where the positivists saw logical compulsion as the reason for theory change, Kuhn saw psychology in values as relevant to how theories are actually confirmed or accepted by the scientific community.

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)
[Empiricism, Naturalism, and Ideas] The author analyses the modern reception of key themes in Hume’s philosophy during the past century. The first part presents Hume’s version of three such themes – empiricism, naturalism and the theory of ideas. The following three parts give an exposition of modern forms of each of these themes, with the choice of modern reception being directed to those contemporary authors who not only developed Hume’s motifs in the most original way, but who also explicitly traced (...) the origin of their modern theory to Hume. For this reason, in the second part, which deals with the reception of empiricism in logical positivism, HansReichenbach and his treatment of Hume’s problem of inductive knowledge is discussed. In the third part, dealing with naturalism, the obvious choice is the most influential version of this doctrine in the work of W. V. O. Quine. The fourth part deals with the modern reception of Hume’s theory of ideas in a recent monograph by Jerry Fodor. The author considers Hume’s naturalism as the most live part of Hume’s legacy. Empirismus has, after all, been considerably transformed in content, or has even been rejected by later philosophers; while Fodor’s updating of the theory of ideas does not offer an adequate answer to the question of the place of thinking and intentionality in the material world.

In this dissertation on Hilary Putnam's philosophy, I investigate his development regarding meaning and necessity, in particular mathematical necessity. Putnam has been a leading American philosopher since the end of the 1950s, becoming famous in the 1960s within the school of analytic philosophy, associated in particular with the philosophy of science and the philosophy of language. Under the influence of W.V. Quine, Putnam challenged the logical positivism/empiricism that had become strong in America after World War II, with influential exponents such (...) as Rudolf Carnap and HansReichenbach. Putnam agreed with Quine that there are no absolute a priori truths. In particular, he was critical of the notion of truth by convention. Instead he developed a notion of relative a priori truth, that is, a notion of necessary truth with respect to a body of knowledge, or a conceptual scheme. Putnam's position on necessity has developed over the years and has always been connected to his important contributions to the philosophy of meaning. I study Hilary Putnam's development through an early phase of scientific realism, a middle phase of internal realism, and his later position of a natural or commonsense realism. I challenge some of Putnam’s ideas on mathematical necessity, although I have largely defended his views against some other contemporary major philosophers; for instance, I defend his conceptual relativism, his conceptual pluralism, as well as his analysis of the realism/anti-realism debate.

How are fundamental constants, such as c for the speed of light, related to particular technological environments? Our understanding of the constant c and Einstein’s relativistic cosmology depended on key experiences and lessons learned in connection to new forms of telecommunications, first used by the military and later adapted for commercial purposes. Many of Einstein’s contemporaries understood his theory of relativity by reference to telecommunications, some referring to it as “signal-theory” and “message theory.” Prominent physicists who contributed to it ( (...) class='Hi'>HansReichenbach, Max Born, Paul Langevin, Louis de Broglie, and Léon Brillouin, among others) worked in radio units during WWI. At the time of its development, the old Newtonian mechanics was retrospectively rebranded as based on the belief in a means of “instantaneous signaling at a distance.” Even our thinking about lengths and solid bodies, argued Einstein and his interlocutors, needed to be overhauled in light of a new understanding of signaling possibilities. Pulling a rod from one side will not make the other end move at once, since relativity had shown that “this would be a signal that moves with infinite speed.” Einstein’s universe, where time and space dilated, where the shortest path between two points was often curved and which broke the laws of Euclidean geometry, functioned according to the rules of electromagnetic signal transmission. For some critics, the new understanding of the speed of light as an unsurpassable velocity—a fundamental tenet of Einstein’s theory—was a mere technological effect related to current limitations in communication technologies.

Dans cet article, nous examinerons le thème de la découverte en science. Nous soutiendrons qu’il est possible de définir une stratégie rationnelle soutenant la découverte au moyen du principe de l’abduction. Afin de démontrer cette thèse, il s’agira d’abord de diagnostiquer le problème de la complexité et de l’irrationalité de la découverte scientifique et de considérer la position néo-positiviste endossée par Karl Popper et HansReichenbach, selon laquelle la découverte ne peut faire l’objet d’une étude proprement logique ou (...) épistémologique. Par la suite, l’analyse se concentrera sur la position de Norwood R. Hanson qui, répondant et contredisant celle de Popper et de Reichenbach, affirme qu’il existe une « logique de la découverte », fondée sur le principe de l’abduction. Après avoir déployé l’argument de Hanson et explicité sa conception du principe de l’abduction, nous montrerons, en nous appuyant sur la vision d’Atocha Aliseda, comment l’abduction est liée à la découverte en science. Finalement, nous examinerons la notion d’inférence à la meilleure explication et le concept « d’hypothèse explicative » de Peter Lipton, ce qui permettra d’expliquer dans quelle mesure cette variante de l’abduction nous permet de comprendre les éléments et conditions qui favorisent la génération de découvertes en science.

My dissertation explores the ways in which Rudolf Carnap sought to make philosophy scientific by further developing recent interpretive efforts to explain Carnap’s mature philosophical work as a form of engineering. It does this by looking in detail at his philosophical practice in his most sustained mature project, his work on pure and applied inductive logic. I, first, specify the sort of engineering Carnap is engaged in as involving an engineering design problem and then draw out the complications of design (...) problems from current work in history of engineering and technology studies. I then model Carnap’s practice based on those lessons and uncover ways in which Carnap’s technical work in inductive logic takes some of these lessons on board. This shows ways in which Carnap’s philosophical project subtly changes right through his late work on induction, providing an important corrective to interpretations that ignore the work on inductive logic. Specifically, I show that paying attention to the historical details of Carnap’s attempt to apply his work in inductive logic to decision theory and theoretical statistics in the 1950s and 1960s helps us understand how Carnap develops and rearticulates the philosophical point of the practical/theoretical distinction in his late work, offering thus a new interpretation of Carnap’s technical work within the broader context of philosophy of science and analytical philosophy in general.

The distinction between context of discovery and context of justification points out to the difference between the generation a new idea or hyphotesis and the testing of it. Although the distinction is attributed to HansReichenbach and Karl Popper, Larry Laudan argues that the history of distinction is dates back to the debates of scientific in the seventeenth century. While in the seventeenth and eighteenth centuries there was no need to distinguish between discovery and justification, in the twentieth (...) century discovery and justification were considered two separate processes. In this paper, it will be argued that the distinction between the context of discovery and justification is untenable given that the history of science is a part of scientific research, as expressed by philosophers such as Kuhn and Feyerabend.

The essay “Was ist der Mensch?” appeared for the first time in December 1944 in the German magazine with a hundred years of tradition edited by the publisher J. J. Weber Illustrierte Zeitung Leipzig [Illustrated Magazine Leipzig]. This special cultural edition, entitled Der europäische Mensch [The European Man], which was distributed exclusively abroad, was to be the last volume of the magazine after its final regular issue in September 1994 (No. 5041). Only in 1947, the text was republished, with the (...) same pagination, in a compilation made by J. J. Weber, Vom Wahren, Schönen, Guten. Aus dem Schatz europäischer Kunst und Kultur [On the True, the Beautiful, the Good. From the Treasury of European Art and Culture]. The publisher was expropriated in 1948, and three years later the company was finally removed from the German commercial registry. “Was ist der Mensch?” has never been released in any of Gadamer’s books or separately published in a journal; it also does not appear within the 10 volumes of his Gesammelte Werke [Collected Works]—the only exception is an Italian translation included in a volume devoted to Gadamer’s views on education and the notion of Bildung (cf. Gadamer 2012). The aim of this translation is to make accessible this Gadamer’s quest for the occidental interpretations of human self-consciousness, which has until now been almost unknown and in which, for the first time, Gadamer shows, from a theoretical standpoint, not only his early—although implicit—keen interest in Max Scheler’s anthropology (particularly Scheler’s considerations on the basic historical types of the occidental man’s self-perception in accordance with the basic and underlying concept of human history that still have powerful effectiveness in modern times), but also—at the historical threshold of the imminent ending of World War II—his own concern regarding possible philosophical answers to the question: “What is man?” Cf. especially Scheler 1926 (GW 9, 120–144); 1928 (GW 9, 7–71); 1929 (GW 9, 145–170).

Hans Kelsen's thorough critique of Eric Voegelin's "New Science of Politcs" is - in my oppinion - the best commentary on Voegelin that has been written so far.
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.

Reichenbach's 'principle of the common cause' is a foundational assumption of some important recent contributions to quantitative social science methodology but no similar principle appears in econometrics. Reiss (2005) has argued that the principle is necessary for instrumental variables methods in econometrics, and Pearl (2009) builds a framework using it that he proposes as a means of resolving an important methodological dispute among econometricians. We aim to show, through analysis of the main problem instrumental variables methods are used to (...) resolve, that the relationship of the principle to econometric methods is more nuanced than implied by previous work, but nevertheless may make a valuable contribution to the coherence and validity of existing methods.

Reichenbach’s early solution to the scientific problem of how abstract mathematical representations can successfully express real phenomena is rooted in his view of coordination. In this paper, I claim that a Reichenbach-inspired, ‘layered’ view of coordination provides us with an effective tool to systematically analyse some epistemic and conceptual intricacies resulting from a widespread theorising strategy in evolutionary biology, recently discussed by Okasha (2018) as ‘endogenization’. First, I argue that endogenization is a form of extension of natural selection (...) theory that comprises three stages: quasi-axiomatisation, functional extension, and semantic extension. Then, I argue that the functional extension of one core principle of natural selection theory, namely, the principle of heritability, requires the semantic extension of the concept of inheritance. This is because the semantic extension of ‘inheritance’ is necessary to establish a novel form of coordination between the principle of heritability and the extended domain of phenomena that it is supposed to represent. Finally, I suggest that – despite the current lack of consensus on the right semantic extension of ‘inheritance’ – we can fruitfully understand the reconceptualization of ‘inheritance’ provided by niche construction theorists as the result of a novel form of coordination.

In this essay I revise, based on the notion of the ‘enlightened ruler’ or mingzhu and his critique of the literati of his time, the common belief that Han Fei was an amoralist and an advocate of tyranny. Instead, I will argue that his writings are dedicated to advising those who ought to rule in order to achieve the goal of a peaceful and stable society framed by laws in accordance with the dao.
This paper looks at the critical reception of two central claims of Peter Auriol’s theory of cognition: the claim that the objects of cognition have an apparent or objective being that resists reduction to the real being of objects, and the claim that there may be natural intuitive cognitions of nonexistent objects. These claims earned Auriol the criticism of his fellow Franciscans, Walter Chatton and Adam Wodeham. According to them, the theory of apparent being was what had led Auriol to (...) allow for intuitive cognitions of nonexistents, but the intuitive cognition of nonexistents, at its turn, led to scepticism. Modern commentators have offered similar readings of Auriol, but this paper argues, first, that the apparent being provides no special reason to think there could be intuitions of nonexistent objects, and second, that despite his idiosyncratic account of intuition, Auriol was no more vulnerable to scepticism than his critics.

Han Feizi’s criticisms of Confucian and Mohist political recommendations are often thought to involve materialist or historicist arguments, independently of their epistemological features. Drawing largely on Amia Srinivasan’s recent taxonomy of genealogical arguments, this paper proposes a genealogical reading of passages in “The Five Vermin [五蠹 wudu]” and “Eminence in Learning [顯學 xianxue].” This reveals Han Feizi’s arguments to be more comprehensively appreciated as problematizing Confucian and Mohist political judgments as arising from undermining contingencies, rendering them irrelevant, if not detrimental, (...) to any lasting excellence of a state. In doing this, it is also suggested that there is a ‘master argument’ underlying Han Feizi’s criticisms, according to which the epistemology of the Confucians and Mohists are fundamentally unreliable.

The work of Thomas White represents a systematic attempt to combine the best of the new science of the seventeenth century with the best of Aristotelian tradition. This attempt earned him the criticism of Hobbes and the praise of Leibniz, but today, most of his attempts to navigate between traditions remain to be explored in detail. This paper does so for his ontology of accidents. It argues that his criticism of accidents in the category of location as entities over and (...) above substances was likely aimed at Francisco Suárez, and shows how White’s worries about the analysis of location were linked with his broader cosmological views. White rejects real qualities, but holds that the quantity of a substance is somehow distinct from its bearer. This reveals a common ground with some of his scholastic interlocutors, but lays bare a deep disagreement with thinkers like Descartes on the nature of matter. (shrink)
It is a truism that where one starts from and the direction one goes determines where one ends up. This is no less true in philosophy than elsewhere, and certainly no less true in matters dealing with the relationship between God’s foreknowledge and human free actions. In what follows I will argue that the incompatibilist view that Fischer and others stalwartly defend results from the particular starting point they choose, and that if one adopts a different starting point about divine (...) knowledge the logical incompatibility they envision and philosophically anguish over evaporates.

In lieu of an abstract, here is a brief excerpt of the content:Spinoza and the Theory of Organism HANS JONAS I CARTESIANDUALISMlanded speculation on the nature of life in an impasse: intelligible as, on principles of mechanics, the correlation of structure and function became within the res extensa, that of structure-plus-function with feeling or experience (modes of the res cogitans) was lost in the bifurcation, and thereby the fact of life itself became unintelligible at the same time that the (...) explanation of its bodily performance seemed to be assured. The impasse became manifest in Occasionalism : its tour de force of an extraneous, divine "synchronization" of the outer and the inner world (the latter denied to animals) not only suffered from its extreme artificiality, the common failing of such ad hoc constructions, but even at so high a cost failed to accomplish its theoretical purpose by its own terms. For the animal machine, like any machine, raises beyond the question of the "how" that of the "what for" of its functioning---of the purpose for which it had thus been constructed by its maker.1 Its performance, however devoid of immanent teleology, must serve an end, and that end must be someone's end. This end may (directly) be itself, as indeed Descartes had implied when declaring self-preservation to be the effect of the functioning of the organic automaton. In that case the existence as such of the machine would be its end--either terminally, or in turn to benefit something else. In the former case, the machine would have to be more than a machine, for a mere machine cannot enioy its existence. But since, by the rigorous conception of the res extensa, it cannot be more than a machine, its function and/or existence must serve something other than itself. Automata in Descartes ' time were mainly for entertainment (rather than work). But the raison d'etre of the living kingdom could not well be seen in God's indulging his mechanical abilities or in the amusement of celestial spectators--especially since mere complexity of arrangement does not create new quality and thus add something to the unrelieved sameness of the simple substratum that might enrich the spectrum of being. For quality, beyond the primitive determinations of the extended per se, is the subjective creature of sensation, the confused representation of quantity in a mind; and thus organisms cannot harbor it because as mere machines they lack mentality, and pure spirits cannot because they lack sensuality, or the privilege of confusion and thereby of illusion with its possible enjoyment. And as to their intellectual enjoyment, even that, deprived of the thrill of discovery by the same token, would pale in the contemplation of what to sufficiently large The concept of "machine," adopted for its strict confinementto efficientcause, is still a finalisticconcept,even thoughthe final cause is no longer internal to the entity, as a mode of its own operation,but external to it as antecedent design. [43] 44 HISTORY OF PHILOSOPHY intellects is nothing but the ever-repeated exemplification of the same few, elementary (and ultimately trivial) truths. There remained, then, the time-honored--Stoic as well as Christian--idea that plants and animals are for the benefit of Man. Indeed, since the existence of a living world is the necessary condition for the existence of any of its members, the self-justifying nature of at least one such member (= species) would justify the existence of the whole. In Stoicism, Man provided this end by his possession of reason, which makes him the culmination of a terrestrial scale of being that is also self-justifying throughout all its grades (the end as the best of many that are good in degrees) ; in Christianity, by his possession of an immortal soul, which makes him the sole imago Dei in creation (the end as the sole issue at stake) ; and Cartesian dualism radicalized this latter position by making man even the sole possessor of inwardness or "soul" of any kind, thus the only one of whom "end" can meaningfully be predicated as he alone can entertain ends. All other life then, the product of physical necessity, can be considered his means. However, this traditional idea, in its anthropocentric vanity never a... (shrink)

The present study aimed to develop effective moral educational interventions based on social psychology by using stories of moral exemplars. We tested whether motivation to engage in voluntary service as a form of moral behavior was better promoted by attainable and relevant exemplars or by unattainable and irrelevant exemplars. First, experiment 1, conducted in a lab, showed that stories of attainable exemplars more effectively promoted voluntary service activity engagement among undergraduate students compared with stories of unattainable exemplars and non-moral stories. (...) Second, experiment 2, a middle school classroom-level experiment with a quasi-experimental design, demonstrated that peer exemplars, who are perceived to be attainable and relevant to students, better promoted service engagement compared with historic figures in moral education classes.

The article endeavours to compare the reflections on the Shoah of two of the most celebrated intellectuals of Jewish origin of the 20th century, namely the German philosopher Hans Jonas and the Soviet writer Vasily Grossman. Both Jonas’ essay on The Concept of God after Auschwitz and Grossman’s novels and reports, such as The Hell of Treblinka, Life and Fate, and The Sistine Madonna, are characterised by a thorough enquiry into the ambivalence of the human condition, that tries to (...) shed some light on the disturbing abyss of Auschwitz and the Shoah. Although neither Jonas nor Grossman considered themselves as religious believers, thanks to the Shoah they recollected their Jewish roots and developed peculiar and innovative thoughts on the meaning and vulnerability of life, human freedom, immortality, and God. The article endeavours to highlight the main similarities and differences between these two authors, who tackled the issue of thinking after Auschwitz. (shrink)
This is a review of From Discourse to Logic: Introduction to Modeltheoretic Semantics of Natural Language, Formal Logic and Discourse Representation Theory, written by Hans Kamp and Uwe Reyle and published by Kluwer Academic Publishers in 1993.
Studie pojednává o analýze a navrhovaném řešení problému „hodnotové neutrality" vědy německým kritickým racionalistou Hansem Albertem. Především Albert odmítá dvě vyhrocené pozice: novopozitivistickou ignoraci hodnotících soudů i jejich existencialistickou adoraci. Naopak se prostřednictvím takzvaných přemosťovacích principů snaží překlenout propast mezi poznáním na jedné straně a rozhodnutím na straně druhé. V návaznosti na Maxe Webera uznává princip hodnotové neutrality ve vědě, ovšem pouze v oblasti jejího objektového jazyka, neboť věda jako technologický systém výpovědí má pouze informativní, nikoli normativní charakter. To však (...) nevylučuje hodnocení v rovině předmětů věd a v rovině hodnotové báze věd. Dále se tato studie věnuje otázce hodnoty vědy o sobě a nakonec krátkému seznámení s Albertovým pojetím kritického racionalismu jako návrhu „způsobu života". (shrink)
Hans Kelsen's thorough critique of Eric Voegelin's "New Science of Politcs" is - in my oppinion - the best commentary on Voegelin that has been written so far.
