From 1901 till, at least, 1919, Russell persistently maintained that there are two kinds of logic, between which he sharply discriminated: mathematical logic and philosophical logic. In this paper, we discuss the concept of philosophical logic, as used by Russell. This was only a tentative program that Russell did not clarify in detail, so our task will be to make it explicit. We shall show that there are three (-and-a-half) kinds of Russellian philosophical logic: (i) “pure logic”; (ii) philosophical logic (...) investigating the logical forms of propositions; (iii) philosophical logic exploring the logical forms of facts: in epistemology; and in the external world. In particular, Russell’s program or philosophical logic of the facts of the external world remained less than sketchily outlined. We shall discuss it in some detail in the hope that it can start a new life. (shrink)

The conception of truth-making, albeit in a rudimentary form, could already be discerned in the writings of G. E. Moore and E. Husserl in the early 1900s. A few years later it was more extensively exploited by William James. It was Wittgenstein, however, who gave the concept a precise meaning. In 1913/1914 Wittgenstein advanced a theory of possible worlds, only one of which was real. Every proposition suggests a part of a possible world which does or does not correspond to (...) parts of the real world. In the first case the proposition is true, in the second case false. Moreover, the part of the real world makes the sentence true. This part is a truth-maker, and the sentence is a truth-bearer. Surprisingly enough, Wittgenstein’s concept of truth-making had its family resemblance with William James’s conception of truth. In 1915 Wittgenstein stopped using the concept of truth-making—it was also not men-tioned in the Tractatus. Unfortunately, Russell did not notice this and in 1918 he adopted the concept of truth-making. In the 1930s, it was used by some second generation analytic philosophers (Schlick, Stebbing, and Wisdom). However, it became rather popular among analytic philosophers only in the 1980s. (shrink)

The present paper has two objectives. First, it explicates the story, initially portrayed by Eckart Förster (2012), that allegedly philosophy started with publishing of Kant’s CPR and ended a quarter century later when Hegel’s Phenomenology of Mind appeared. We address the questions in what sense this happened and how is this development to be interpreted? Secondly, we demonstrate that similar radical transition from new, “true” beginning of philosophy to its apparent finishing took place in two other, high profile occasions in (...) the history of Western philosophy, in two key points of its development: in the years 390–365 BC, between the early and the late Plato, and between 1898 and 1922, between Russell and Wittgenstein’s Tractatus. These three short-lived, spectacular transitions from philosophy’s alleged start to its alleged ultimate accomplishment give us good reason to speak about a specific 25-years principle in philosophy. In a peculiar way, this principle reveals philosophy’s true nature. (shrink)

The impacts that AI and robotics systems can and will have on our everyday lives are already making themselves manifest. However, there is a lack of research on the ethical impacts and means for amelioration regarding AI and robotics within tourism and hospitality. Given the importance of designing technologies that cross national boundaries, and given that the tourism and hospitality industry is fundamentally predicated on multicultural interactions, this is an area of research and application that requires particular attention. Specifically, tourism (...) and hospitality have a range of context-unique stakeholders that need to be accounted for in the salient design of AI systems is to be achieved. This paper adopts a stakeholder approach to develop the conceptual framework to centralize human values in designing and deploying AI and robotics systems in tourism and hospitality. The conceptual framework includes several layers – ‘Human-human-AI’ interaction level, direct and indirect stakeholders, and the macroenvironment. The ethical issues on each layer are outlined as well as some possible solutions to them. Additionally, the paper develops a research agenda on the topic. (shrink)

The received view has it that analytic philosophy emerged as a rebellion against the German Idealists (above all Hegel) and their British epigones (the British neo-Hegelians). This at least was Russell’s story: the German Idealism failed to achieve solid results in philosophy. Of course, Frege too sought after solid results. He, however, had a different story to tell. Frege never spoke against Hegel, or Fichte. Similarly to the German Idealists, his sworn enemy was the empiricism (in his case, John Stuart (...) Mill). Genealogically, this stance is not difficult to explain. Frege grew up as a philosopher in the context of the German Idealists. He was a member of Karl Snell’s “Sunday Circle” of university teachers in Jena. The group was influenced with Schelling and the German romanticists. The first Anglophone scholar to point out what Frege's thought owes to nineteenth-century Germany philosophy, Hans Sluga, argued that Frege followed the philosophical-logical tradition originating with Leibniz and Kant which Trendelenburg and Lotze developed significantly. About the same time, a philosophical historian writing in German, Gottfried Gabriel, did much to bring this tradition to light, casting Frege as neo-Kantian. Advancing beyond Sluga and Gabriel, the present paper reveals that through the mediation of Trendelenburg and especially of Lotze many elements of German idealism found their way into Frege's logic and philosophy.

Shortly before G. E. Moore wrote down the formative for the early analytic philosophy lectures on Some Main Problems of Philosophy (1910–1911), he had become acquainted with two books which influenced his thought: (1) a book by Husserl's pupil August Messer and (2) a book by the Greifswald objectivist Dimitri Michaltschew. Central to Michaltschew's book was the concept of the given. In Part I, I argue that Moore elaborated his concept of sense-data in the wake of the Greifswald concept. Carnap (...) did the same when he wrote his Aufbau, the only difference being that he spoke not of sense-data but of Erlebnisse. This means, I argue, that both Moore's sense-data and Carnap'sErlebnisse have little to do with either British empiricists or the neo-Kantians. In Part II, I try to ascertain what made early analytic philosophy different from all those philosophical groups and movements that either exercised influence on it, or were closely related to it: phenomenologists, Greifswald objectivists, Brentanists. For this purpose, I identify the sine qua non practices of the early analytic philosophers: exactness; acceptance of the propositional turn; descriptivism; objectivism. If one of these practices was not explored by a given philosophical school or group, in all probability, it was not truly analytic. (shrink)

Russell’s initial project in philosophy (1898) was to make mathematics rigorous reducing it to logic. Before August 1900, however, Russell’s logic was nothing but mereology. First, his acquaintance with Peano’s ideas in August 1900 led him to discard the part-whole logic and accept a kind of intensional predicate logic instead. Among other things, the predicate logic helped Russell embrace a technique of treating the paradox of infinite numbers with the help of a singular concept, which he called ‘denoting phrase’. Unfortunately, (...) a new paradox emerged soon: that of classes. The main contention of this paper is that Russell’s new conception only transferred the paradox of infinity from the realm of infinite numbers to that of class-inclusion. Russell’s long-elaborated solution to his paradox developed between 1905 and 1908 was nothing but to set aside of some of the ideas he adopted with his turn of August 1900: (i) With the Theory of Descriptions, he reintroduced the complexes we are acquainted with in logic. In this way, he partly restored the pre-August 1900 mereology of complexes and simples. (ii) The elimination of classes, with the help of the ‘substitutional theory’, and of propositions, by means of the Multiple Relation Theory of Judgment, completed this process. (shrink)

The Berlin Group was an equal partner with the Vienna Circle as a school of scientific philosophy, albeit one that pursued an itinerary of its own. But while the latter presented its defining projects in readily discernible terms and became immediately popular, the Berlin Group, whose project was at least as sig-nificant as that of its Austrian counterpart, remained largely unrecognized. The task of this chapter is to distinguish the Berliners’ work from that of the Vienna Circle and to bring (...) to light its impact in the history of scientific philosophy. (shrink)

Two concepts of utmost importance for the analytic philosophy of the twentieth century, “sense-data” and “knowledge by acquaintance”, were introduced by Bertrand Russell under the influence of two idealist philosophers: F. H. Bradley and Alexius Meinong. This paper traces the exact history of their introduction. We shall see that between 1896 and 1898, Russell had a fully-elaborated theory of “sense-data”, which he abandoned after his analytic turn of the summer of 1898. Furthermore, following a subsequent turn of August 1900—-after he (...) became acquainted with the works of Peano and later of Frege—-Russell gradually developed another theory of sense-data. With the collaboration of G. E. Moore, Russell reintroduced the term “sense-data” in 1911. Concomitantly with this move, Russell introduced the epistemological term “knowledge by acquaintance”, which came to designate the grasping of sense-data and universals. (shrink)

The present essay advances a theory of social reality which concurs with the formal ontology developed in Wittgenstein’s Tractatus. Furthermore, we identify this formal ontology as reistic but in a rather wide sense: in the sense that social objects are primary whereas social relations are super-structured over them. This thesis has been developed in opposition to John Searle’s claim, made in his book Construction of Social Reality (1995), that the building blocks of social reality are institutions. We do not claim (...) that this is the only valid theory of social reality. We simply hope that it has considerable ex-planatory power so that it can be used as a theory alternative to those already existing or to any new theory of society. The paper has two parts. Part One sets out the theoretical foundations of the approach followed in it, whereas Part Two advances details of its application to sociology and history. (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 Hans Reichenbach’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.

Between April and November 1912, Bertrand Russell and Ludwig Wittgenstein were engaged in a joint philosophical program. Wittgenstein‘s meeting with Gottlob Frege in December 1912 led, however, to its dissolution – the joint program was abandoned. Section 2 of this paper outlines the key points of that program, identifying what Russell and Wittgenstein each contributed to it. The third section determines precisely those features of their collaborative work that Frege criticized. Finally, building upon the evidence developed in the preceding two (...) sections, section 4 recasts along previously undeveloped lines Wittgenstein‘s logical–philosophical discoveries in the two years following his encounter with Frege in 1912. The paper concludes, in section 5, with an overview of the dramatic consequences the Frege-Wittgenstein critique had for Russell‘s philosophical development. (shrink)

Historians of philosophy commonly regard as antipodal Bertrand Russell and Edmund Husserl, the founding fathers of analytic philosophy and phenomenology. This paper, however, establishes that during a formative phase in both of their careers Russell and Husserl shared a range of seminal ideas. In particular, the essay adduces clear cases of family resemblance between Husserl’s and Russell’s philosophy during their middle period, which spanned the years 1905 through 1918. The paper thus challenges the received view of Husserl’s relation to early (...) analytic philosophy and this by pursuing two strategies of exposition. One involves comparing Husserl with Russell, and not, as has been the usual practice, with Frege. The other, which follows the first, foregrounds Husserl’s thinking vis-à-vis Russell’s from 1905 onward, a move that constitutes a break with what has become the standard approach of emphasising the relatedness of Husserl of the Logical Investigations (1900/1) to analytic philosophy. Moreover, this approach discloses two chief grounds of relatedness between the middle Husserl and the middle Russell. One is their shared interest in exploring philosophical “fundamentals”. The second consists of common elements shared by their epistemologies and philosophies of mind. (shrink)

I argue that an analogy between pains and sounds suggests a way to give an objective account of pain which fits well with a naïve perceptualist account of feeling pain. According to the proposed metaphysical account, pains are relational physical events with shared qualitative nature, each of which is constituted by tissue damage and the activation of nociceptors. I proceed to show that the metaphysical proposal is compatible with platitudes about pains being animate, private, and self-intimating states.

Many historians of analytic philosophy consider the early philosophy of Moore, Russell and Wittgenstein as much more neo-Hegelian as once believed. At the same time, the authors who closely investigate Green, Bradley and Bosanquet find out that these have little in common with Hegel. The thesis advanced in this chapter is that what the British (ill-named) neo-Hegelians brought to the early analytic philosophers were, above all, some ideas of Lotze, not of Hegel. This is true regarding: (i) Lotze’s logical approach (...) to practically all philosophical problems; (ii) his treating of the concepts relation, structure (constructions) and order; (iii) the discussion of the concepts of states of affairs, multiple theory of judgment, general logical form; (iv) some common themes like panpsychism and contemplating the world sub specie aeternitatis.

Hermanns Lotze (1817–1881) hat nachweislich einige der bedeutendsten Philosophen des fin de siècle beeinflusst: (i) die britischen „Neo-Hegelianer“; (ii) Husserls Phänomenologie; (iii) Diltheys Philosophie des Lebens; (iv) die Neukantianer; (v) die frühere analytische Philosophie. Das angegebene Ziel seines dreibändigen Mikrokosmos (1856–1864) war „die Reflexion über den Sinn unseres menschlichen Daseins“. Die Aktualität dieser Aufgabe war eine Folge der wissenschaftlichen und industriellen Revolution Mitte des 19. Jahrhunderts. Sie veränderte die Art, wie sich die Menschen das Universum vorstellten. Lotze sah Gefahr in (...) den zahlreichen Versuchen seitens einiger philosophisch interessierter Wissenschaftler in Deutschland, zu beweisen, dass das menschliche Sein nur mechanisch und materialistisch zu verstehen ist. Er machte es sich zur Aufgabe, den Menschen das Gefühl von Heimat in dieser stark veränderten Welt zurückzugeben. Dies erklärt auch, wieso Lotze seine Untersuchung in „völlig populärer Form“ darstellte. Lotzes Mikrokosmos war jedoch nicht nur ein Werk der populären Philosophie. Sie fußt auf fundierten theoretischen Überlegungen. Man kann Lotzes Werk als einen gewagten Versuch betrachten, die sich abzeichnende Spaltung zwischen akademischer und populärer Philosophie zu überwinden. (shrink)

When Wittgenstein started writing the Tractatus in June 1915, he was convinced that he was producing a theory. Accordingly, he chose a theoretical style of expressing his thought. Wittgenstein abandoned this stance only at the end of his work of composing the book. He realized that what he is producing in not a theory but a manual for improving our language and thinking. Unfortunately, it was too late to change the architecture and the style of the book: Wittgenstein simply had (...) no time to do that. This drawback makes the Tractatus notoriously difficult to understand and is apparently the major factor that caused the so called “Tractarian Wars”. (shrink)

Karl Popper has often been cast as one of the most solitary figures of twentieth-century philosophy. The received image is of a thinker who developed his scientific philosophy virtually alone and in opposition to a crowd of brilliant members of the Vienna Circle. This paper challenges the received view and undertakes to correctly situate on the map of the history of philosophy Popper’s contribution, in particular, his renowned fallibilist theory of knowledge. The motive for doing so is the conviction that (...) the mainstream perspective on Popper’s philosophy makes him more difficult to understand than might otherwise be the case. The thinker who figures most significantly in the account of Popper developed in these pages is Leonard Nelson. Both a neo-Friesian and neo-Kantian, this philosopher deeply influenced Popper through his student Julius Kraft, who met with Popper on numerous occasions in the mid 1920s. It is in the light of this influence that we understand Popper’s recollection that when he criticized the Vienna Circle in the early 1930s, he looked upon himself “as an unorthodox Kantian”.

This paper introduces a novel interpretation of Wittgenstein’s Tractatus, a work widely held to be one of the most intricate in the philosophical canon. We understand the Tractatus not as the development of a theory but as the advancement of a new logical symbolism (a new instrument) that enables one to “recognize the formal properties [the logic] of propositions by mere inspection of propositions themselves” (6.122). Moreover, the Tractarian conceptual notation stands to instruct us in a better way to follow (...) the logic of language, and by that token, enhances our ability to think. Upon acquiring the thinking skills that one can develop by working with this symbolism, one can “throw away [this] ladder” (6.54), as it were, and move on. (shrink)

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, Hans Reichenbach 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)

Philosophy is deeply rooted in human nature. On the one hand, thinking of an infinite essence of the universe may actualize an infinite essence of humans themselves and thus root them in the Cosmos infinity. On the other hand, to think of infinity is to acquire the power of infinity, i.e., an infinite power. In short, thinking in terms of infinity fills us with infinity. Philosophy allows individuals to overstep the limits of the lived experience, transcends their Selves beyond daily (...) occurrence. Obviously, just this human transcendence into metaphysical reality, into the world of essential relationships ensures a therapeutic effect of philosophy. (shrink)

State of affairs (Sachverhalt) is one of the few terms in philosophy, which only came into use for the first time in the twentieth century, mainly via the works of Husserl and Wittgenstein. This makes the task of finding out who introduced this concept into philosophy, and in exactly what sense, of considerable interest. Our thesis is that Lotze introduced the term in 1874 in the sense of the objective content of judgments, which is ipso facto the minimal structured ontological (...) unit. We would argue against authors such as Michael Dummett and Barry Smith, who have tried to prove that Lotze's theory of judgment, and so of states of affairs, was ad-vanced in the wake of psychologism.

The paper discusses Leo Tolstoy's philosophy as developed in his works 'A Synoptic Presentation of the Four Gospels' and 'The Gospel in Brief'. Tolstoy considered Christian religion not as a belief but as an ethical doctrine about how to live, so that our life does not lose its meaning when confronted with the death. Jesus' doctrine teaches that we must lead our life following our spirit, not our flesh. This means that we must strive to understand other persons and to (...) be good to them. Then God will stay with us and we will lose our fear of the death.. (shrink)

The task of this paper is to reconstruct Bertrand Russell project for religion without God and dogma. Russell made two attempts in this direction, first in the essay “Free Man’s Worship” (1903), and then, in theoretical form, in the paper “The Essence of Religion” (1912). Russell’s explorations of religious impulses run in parallel with his work on technical philosophy. According to Russell from 1903–12, religion is an important part of human pursuits. However, whereas the ordinary man believes in God, the (...) freeman embraces a religion without fear and dogma. He strives for a union with the universe achieved in contemplation made from many perspectives through “impartiality of vision”. For this reason freemen renounce the Self and the Will. Russell abandoned his project for religion without God mainly because of Wittgenstein’s criticism. In his later writings he continued to criticize the religion of the ordinary man, without to further develop a positive philosophy of religion, though. (shrink)

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)

The task of this paper is to show that Franz Brentano was not a solitary figure who advanced his philosophy in complete isolation from other contemporary philosophers in Germany, as some Neo-Brentanists have claimed over the last 30–40 years. He developed his philosophical psychology in the context of his time—in particular, under the influence of Hermann Lotze.

Carl Stumpf (1848–1937) is a key figure in the fin de siècle germanophone philosophy. Unfortunately, after the World War One, the interest towards Stumpf as a philosopher waned. One of the reasons was that already in the 1920s the attention of the mainstream philosophers shifted in direction of the rising rivalry between analytic and continental philosophy. The interest towards Carl Stumpf’s philosophy was revived only in the last twenty years or so. Great service in this provided the Neo-Brentanists. But while (...) the association of Carl Stumpf with Franz Brentano fostered Stumpf studies, it also gave rise of one-sided interpretations of Stumpf as a philosopher. In this way his importance and idiosyncrasy as philosopher remained in shadow. (shrink)

Susan Stebbing’s paper “Logical Positivism and Analysis” (March 1933) was unusually critical of Wittgenstein. It put up a sharp opposition between Cambridge analytic philosophy of Moore and Russell and the positivist philosophy of the Vienna Circle to which she included Wittgenstein from 1929–32. Above all, positivists were interested in analyzing language, analytic philosophers in analyzing facts. Moreover, whereas analytic philosophers were engaged in directional analysis which seeks to illuminate the multiplicity of the analyzed facts, positivists aimed at final analysis which (...) “proves” that there are simples. Stebbing’s paper urged Wittgenstein to recast his philosophy and 1933 abandon those components of it that linked him to the Vienna Circle. (shrink)

Gottlob Frege’s conception of works of art has received scant notice in the literature. This is a pity since, as this paper undertakes to reveal, his innovative philosophy of language motivated a theoretically and historically consequential, yet unaccountably marginalized Wittgenstinian line of inquiry in the domain of aesthetics. The element of Frege’s approach that most clearly inspired this development is the idea that only complete sentences articulate thoughts and that what sentences in works of drama and literary art express are (...) ‘mock thoughts’ (Schiengedanken). The early Wittgenstein closely followed Frege’s lead on this theme. One sees this, for example, in the Tractatus, where Wittgenstein announces that only sentential propositions model (‘picture’) states of affairs whereas works of art are objects we perceive sub specie aeternitatis (1961, 83). By the 1930s, however, Wittgenstein began to revise his view beyond his initial Frege-inspired standpoint. He came to insist that works of art can convey thoughts as well, but that thoughts do not model (picture) the world of facts and hence do not convey information about measurable objects and events. Rather, his contention was that aesthetically configured thoughts that artworks communicate impart information about our perspective on reality and reconfigure our view of life. To be more explicit, successful (gelungene) or ‘good’ works of art (ibid.), in Wittgenstein’s view, can supply aesthetically instructive ‘gestures’ that open to living experience promising new ways of being. It is in this respect, he held, that artists ‘have something to teach’ (1980, 36). (shrink)

In parts of his Notebooks, Tractatus and in “Lecture on Ethics”, Wittgenstein advanced a new approach to the problems of the meaning of life. It was developed as a reaction to the explorations on this theme by Bertrand Russell. Wittgenstein’s objective was to treat it with a higher degree of exactness. The present paper shows that he reached exactness by treating themes of philosophical anthropology using the formal method of topology.

Lotze’s "Microcosm" was published in three volumes, in 1856, 1858 and 1864, respectively. It was soon one of the most widely read philosophy books of the time. It was translated into French and Russian immediately, into English in 1885/87, and into Italian in 1911/16. The book saw six editions in Germany alone by 1923.

In trying to answer the question What is analytic philosophy? I shall follow two methodological principles. (i) The first was suggested by Peter Hacker and reads: ‘Any characterisation of “analytic philosophy” which excludes Moore, Russell and the later Wittgenstein, as well as the leading figures of post War analytic philosophy [for us these are John Wisdom, Ryle, Austin, Strawson and Dummett], must surely be rejected.’ (Hacker 1996a, p. 247) The correct definition of analytic philosophy must cohere with the philosophy of (...) its generally recognized founding fathers. (ii) Any characterisation of ‘analytic philosophy’ which was massively represented in the history of philosophy in the past, must be rejected too. To be sure, Moore, Russell and Wittgenstein, and later also Ryle, Austin and their friends, were doing a type of philosophy which they consciously understood as new—it was intrinsically New Philosophy. The problem was only that this newness was difficult to identify and define. (shrink)

In this paper we shall open a perspective from which the relatedness between the early analytic philosophy and Husserl’s phenomenology is so close that we can call the two programs with one name: “rigorous philosophy”, or “theory of forms”. Moreover, we shall show that the close relatedness between the two most influential philosophical movements of the 20th century has its roots in their common history. At the end of the paper we shall try to answer the question why being rather (...) related at the beginning, their ways parted in the subsequent years. (shrink)

Many authors believe that the manuscripts Frege wrote in 1924–1925 are not theoretically of interest. They are rather a product of his emotional despair and theoretical dead-end which he reached in the last years of his life. Such is also the judgement of Michael Dummett delivered in his seminal book Frege: Philosophy of Language. According to Dummett, “the few fragmentary writings of Frege’s final period—1919–1925—are not of high quality: they are interesting chiefly as showing that Frege did, at least at (...) the very end of his life, acknowledge the failure of the logicist programme” (Dummett 1981, p. 664). In this paper we will try to show that the widely accepted negative assessment of Frege’s latest writings is due to a lack of understanding of their true idea. In fact, the change in Fre-ge’s mind in the last two or three years of his life was result of long deliberations on a severe tension in his founding intuitions. The change itself made his logico-philosophical project more coherent and, thus, is of utmost theoretical importance. (shrink)

The paper investigates the history of the introduction of what was later called “analytic philosophy” in October 1911–May 1912. Despite the fact that Russell and Wittgenstein were in full agreement in their antipathy towards the old-style philosophy, for example, that of Bergson, each had his own conception of the New Philosophy. For Russell, it meant “examined philosophy”, or philosophy advanced through “scientific restraint and balance” of our theoretical conjectures, and resulted in a series of logically correctly constructed theories. For Wittgenstein, (...) it resulted in syncopated, short logical-philosophical “discoveries”. In the years to come, the two conceptions of “rigorous philosophy” embraced by Russell and Wittgenstein often came in conflict. (shrink)

The conventional wisdom has it that between 1905 and 1919 Russell was critical to pragmatism. In particular, in two essays written in 1908–9, he sharply attacked the pragmatist theory of truth, emphasizing that truth is not relative to human practice. In fact, however, Russell was much more indebted to the pragmatists, in particular to William James, as usually believed. For example, he borrowed from James two key concepts of his new epistemology: sense-data, and the distinction between knowledge by acquaintance and (...) knowledge by description. Reasonable explanation of this is that, historically, Russell’s logical realism and James’s pragmatism have the same roots—the German philosopher Rudolph Hermann Lotze (1817–1881). In this paper we are going to explore the fact that in 1905, under Lotze’s influence, Russell married propositions with beliefs. A few years later this step also made Russell prone to embrace the theory of truth-making that has its roots in James. In contrast to the concept of sense-data and to the distinction between knowledge by acquaintance and knowledge by description, however, the understanding that we believe propositions—and not, for example, simply grasp them—was in tension with Russell’s Principle of Extensionality, according to which propositions can be logically connected with other propositions only as truth-functions. The point is that when we judge a mind-relation (for example, a relation of belief) to a proposition, the latter cannot be determined as true or false. The two most talented pupils of Russell, Wittgenstein and Ramsey, severely criticized the central place propositional attitudes play in Russell’s logic. Wittgenstein analyzed “A believes that p” to “ ‘p’ says p” (5.542). Ramsey criticized Russell’s beliefs in propositions the other way round: He stressed that belief is an ambiguous term that can be interpreted for the better in the sense of pragmatism. Prima facie surprisingly, he maintained that his “pragmatism is derived from Mr Russell.” (1927: 51). (shrink)

Husserl’s theory of manifolds was developed for the first time in a very short form in the Prolegomena to his Logical Investigations, §§ 69–70 (pp. 248–53), then repeatedly discussed in Ideas I, §§ 71–2 (pp. 148–53), in Formal and Transcendental Logic, §§ 51–4 (pp. 142–54), and finally in the Crisis, § 9 (pp. 20–60). Husserl never lost sight of it: it was his idée fixe. He discussed this theme over forty years, expressing the same, in principle, ideas on it in (...) different terms and versions. His discussions of it, however, were always cut short and inconclusive, so that he never developed his theory of manifolds in detail. Main claim in this essay is that Husserl’s theory of manifolds is twofold. It is (1) a theory of theories, advanced in the good German tradition of Wissenschaftslehre, launched first by Bernard Bolzano. The latter, in turn, is an offspring of the ancient tradition of mathesis universalis, explored in the modernity by Descartes and Leibniz. Further, (2) the theory of manifolds is also a formal theory of everything. Its objective is to provide a systematic account of how the things in the world (its parts) hang together in wholes of quite different kind. It is to be noted that Husserl explicitly speaks about (1) and only implicitly about (2). In this paper we shall also show that the theory of everything is intrinsically connected with the theory of theories. (shrink)

This paper advances an assessment of Kant’s Critique of Pure Reason made from a bird’s eye view. Seen from this perspective, the task of Kant’s work was to ground the spontaneity of human reason, preserving at the same time the strict methods of science and mathematics. Kant accomplished this objective by reviving an old philosophical discipline: the peirastic dialectic of Plato and Aristotle. What is more, he managed to combine it with logic. From this blend, Kant’s transcendental idealism appeared as (...) a new logic that paralleled Aristotle’s syllogistic logic. The first result of this move was that philosophy became a formal study that treats even such subjects as ethics with rigour. Another outcome was that it established philosophy as a professional – school – discipline. In the twentieth century academy, this development was echoed by the emergence of analytic philosophy, in which Kant’s new logic evolved into a philosophical logic. (shrink)

The present paper considers using Social Networking Sites (SNS) as the primary means of communication . Current situations of communication are often associated with the active use of various SNS - convenient tool for information exchange, as new media, and one of the most widespread ways of self-presentation. The author comes to the conclusion that a SNS (like Facebook) gives no effective means to discern the real face - ego-, personal or actual social identity. However, modern Internet technologies provide us (...) with useful instruments, applied to the social network analysis and semiotic approach, to define the virtual social (or personal) identity that can (or cannot) be the same as the real one.

Die Psychologie hat sich im zweiten Viertel des 19. Jahrhunderts langsam zu einer autonomen Disziplin entwickelt. Im Unterschied zu den anderen Figuren in dieser Entwicklung, Johann Friedrich Herbart, Ernst Heinrich Weber und Gustav Theodor Fechner, hat Lotze in seiner Medicinische Psychologie (1852) von Anfang an die neue Disziplin, die Psychologie, konsequent in enger Verbindung mit der Philosophie entwickelt. Damit hat er die Hoffnung gebremst, die Psychologie völlig experimentellen Untersuchungen zu überlassen, die um diese Zeit schon viele gepflegt haben. Lotze scheute (...) sich jedoch, diese Disziplin „philosophische Psychologie“ zu benennen. Sie war für ihn nur physiologische Psychologie, herausarbeitet mit Hilfe der Philosophie. Sie stellt nur Tatsachen fest, untersucht wie Körper und Seele sich zueinander verhalten und dies nicht nur empirisch, sondern auch „metaphysisch“. (shrink)

In the late 1920s and early 1930s, the philosopher Hans Reichenbach 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.

It is generally acknowledged that Kant’s new “transcendental” philosophy produced a “Copernican revolution” in this discipline. Instead to philosophically explore the world, Kant investigated the possibility of cognizing the world through human reason. Unfortunately, it is not thus clear which exactly method helped Kant to produce it. The claim of the present paper is that Kant’s new approach in philosophy went together with a change of the style followed in this discipline. Instead of doing philosophical “meditations” (like Descartes) or composing (...) philosophical “essays” (like Locke and Hume), Kant introduced, what we call here, a diachronic encyclopedic approach of doing philosophy, which was brought about in the context of the highly influential in his years Encyclopédie of D’Alembert and Diderot. In contrast to the latter, however, Kant’s project prompted a logical unification of all substantial ideas introduced in philosophy so far. (shrink)

The received view has it that Hans Reichenbach 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)

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 Hans Reichenbach 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)

In the last decades, several attempts were made to exploit the relatedness between the early analytic philosophers and Hegel. Some 30 years ago, Peter Hylton and Nicholas Griffin investigated the apprenticeship of Bertrand Russell with neo-Hegelians. 25 years later, the direction of interest changed. Paul Redding and Angelica Nuzzo sought a connection between Hegel and analytic philosophy following hints made by Robert Brandom and John McDowell. According to these authors, Hegel can be seen as a theorist of concepts. Moreover, they (...) found that Hegel’s understanding of concepts is close to that of the early analytic philosophy. The approach we are following in this paper is different. We shall concentrate on the relatedness between the method of the early analytic philosophers and aspects of Hegel’s method. This is an unexplored venue and we hope that our study will open a new perspective both in the history of the early analytic philosophy and in Hegel Studies. To be more explicit, we are not going to specifically investigate the genealogical connection between these two methods. We shall be mainly concerned with their kinship. (shrink)
