The Warsaw School of Logic (WSL) was the famous branch of the Lvov-Warsaw School (LWS) – the most important movement in the history of Polish philosophy. Logic made the most important field in the activities of the WSL. The aim of this work is to highlight the role and significance of the WSL in the history of logic in the 20th century.

Fichte’s Foundations of the Entire Wissenschaftslehre 1794 is one of the most fundamental books in classical German philosophy. The use of laws of thought to establish foundational principles of transcendental philosophy was groundbreaking in the late eighteenth and early nineteenth century and is still crucial for many areas of theoretical philosophy and logic in general today. Nevertheless, contemporaries have already noted that Fichte’s derivation of foundational principles from the law of identity is problematic, since Fichte lacked the tools to correctly (...) present the formal parts of Foundations. In this paper, however, we argue that Fichte’s approach intuitively offers an important contribution to transcendental philosophy, and especially to philosophy of logic. We first point out the difficulties of Fichte’s logic in the Foundations and improve it in a second part on the basis of a formal system in which both propositional logic and syllogistic are combined.

This article explores the question of how the members of the Lvov-Warsaw School promoted values that can be regarded as components of so-called logical culture. The author argues that these values are strictly connected with science. With references to Łukasiewicz, Czeżowski, and Kotarbiński,the article explores how values shape the logical culture and determines society as directed towards values. The article connects the meta-philosophical perspective with the philosophical one.

Maria Kokoszyńska-Lutmanowa was one of the most outstanding female representatives of the Lvov-Warsaw School. After achieving her PhD in philosophy under Kazimierz Twardowski’s supervision, she was Kazimierz Ajdukiewicz’s assistant. She was also influenced by Alfred Tarski whose results in semantics she analyzed and popularized. After World War II, she got the chair of logic in University of Wrocław and she organized studies in logic in this academic center. In the 1930s, Kokoszyńska kept in contact with members of the (...) Vienna Circle and became a kind of connecting factor between Polish logicians and the Viennese group. In Poland, she presented the views of members of the Vienna Circle. In Vienna, she emphasized the results of her Polish colleagues. In the present paper, some of Kokoszyńska’s results connected with the matters discussed in the Vienna Circle are presented, namely with the problem of metaphysics, the status of logic and the idea of unity of science.

The Introduction outlines, in a concise way, the history of the Lvov-Warsaw School—a most unique Polish school of worldwide renown, which pioneered trends combining philosophy, logic, mathematics and language. The author accepts that the beginnings of the School fall on the year 1895, when its founder Kazimierz Twardowski, a disciple of Franz Brentano, came to Lvov on his mission to organize a scientific circle. Soon, among the characteristic features of the School was its serious approach (...) towards philosophical studies and teaching of philosophy, dealing with philosophy and propagation of it as an intellectual and moral mission, passion for clarity and precision, as well as exchange of thoughts, and cooperation with representatives of other disciplines. The genesis is followed by a chronological presentation of the development of the School in the successive years. The author mentions all the key representatives of the School, accompanying the names with short descriptions of their achievements. The development of the School after Poland’s regaining independence in 1918 meant part of the members moving from Lvov to Warsaw, thus providing the other segment to the name—Warsaw School of Logic. The author dwells longer on the activity of the School during the Interwar period—the time of its greatest prosperity, which ended along with the outbreak of World War 2. Attempts made after the War to recreate the spirit of the School are also outlined and the names of continuators are listed accordingly. The presentation ends with some concluding remarks on the contribution of the School to contemporary developments in the fields of philosophy, mathematical logic or computer science in Poland.

The ‘Warsaw School of History of Ideas’ is the name given to a ‘revisionist think tank’ which was led by the historian Bronisław Baczko from 1956 to 1968 in Communist Poland. This group reunited scholars like Leszek Kołakowski or Krzysztof Pomian around questions related to political believes, theological conceptions or utopian thought. Expelled from the University, B. Baczko left Poland and seek shelter in Geneva where he became a Professor of history of Ideas and historiography. In his new (...) home, he developed an original vision on Enlightenment and the French Revolution. (shrink)

Kotarbiński is one of the leading figures in the Lvov-Warsaw school of Polish philosophy. We summarize the development of Kotarbiński’s thought from his early nominalism and ‘pansomatistic reism’ to the later doctrine of ‘temporal phases’. We show that the surface clarity and simplicity of Kotarbiński’s writings mask a number of profound philosophical difficulties, connected above all with the problem of giving an adequate account of the truth of contingent (tensed) predications. The paper will examine in particular the attempts (...) to resolve these difficulties on the part of Leśniewski. It will continue with an account of the relations of Kotarbińskian reism to the ontology of things or entia realia defended by the later Brentano. Kotarbiński’s identification of Brentano as a precursor of reism is, it will be suggested, at least questionable, and the paper will conclude with a more careful attempt to situate the Brentanian and Kotarbińskian ontologies within the spectrum of competing ontological views.

The aim of this paper is to show that the account of objective truth taken for granted by logicians at least since the publication in 1933 of Tarski’s “The Concept of Truth in Formalized Languages” arose out of a tradition of philosophical thinking initiated by Bolzano and Brentano. The paper shows more specifically that certain investigations of states of affairs and other objectual correlates of judging acts, investigations carried out by Austrian and Polish philosophers around the turn of the century, (...) formed part of the background of views that led to standard current accounts of the objectivity of truth. It thus lends support to speculations on the role of Brentano and his heirs in contemporary logical philosophy advanced by Jan Wolenski in his masterpiece of 1989 on the Logic and philosophy in the Lvov-Warsaw School.

The article presents ethical work of an outstanding representative of the philosophical Lvov-Warsaw School – Izydora Dąmbska. The conviction that philosophy is a science and is axiologically grounded was inherited from her teacher Kazimierz Twardowski. According to this point of view, being a philosopher means realization of both intellectual and moral values. The text gives an insight into the ways Dąmbska understands the term ethics and her notion of the most fundamental terms of axiological ethics: assessment, values, norms. (...) The four distinguished by her issues of scientific ethics: the issue of ethical criteria, sources of morality, moral foundation and range of ethics are also examined. Dąmbska’s achievements in the history of ethics, her reflections on ethics’ independence from religion and on teaching ethics at school are also presented. (shrink)

In the period after the First World War when the various national-ideological “truths” that led to it were not well resolved which resulted in the Second World War, one of the greatest world crises occurs. In those turbulent times, one philosopher renounces his national identity (changes his religion and name), wanting not to save himself from an evil world that is emerging but to join the creation of a completely new world – the world of modern logic. This man is (...) Alfred Tarski, whom many recognize as “the man who defined truth”, linking him to the formulation of the distinction between object and metalanguage. In the paper, I argue with historians of philosophy who claim that this distinction was first set by the logician and philosopher of the Lvov-Warsaw school Stanislaw Leśniewski (whose Tarski was the only doctoral student) accusing Tarski of violating professional laws without attributing the authorship of this distinction to Leśniewski. I show that this is not true and I cite the places where Tarski clearly emphasizes Leśniewski ‘s contribution. (shrink)

„Ruch Filozoficzny” and the freedom of scientific research in Poland (in 1947-1957 years). Presented article refers to the situation in the Polish philosophy, which took place between 40-50 of the twentieth century. Author’s reflections are carried on the example of attempts to reactivate in the realities of war, the polish philosophical journal “Ruch Filozoficzny” founded in 1911 by Kazimierz Twardowski. Political conditions have made the magazine was renewed twice, at each time was the greatest merit of Tadeusz Czeżowski. He was (...) assisted by the other representatives of the Lvov-Warsaw School, who worked in various academic centers in Poland. The reconstruction of the history of the magazine in the postwar years, will be based on previously unpublished archival material. In its conclusions, the author tries to point out of great importance of independent from the political authorities publishers on development of Polish philosophy. (shrink)

From the European point of view Zbigniew Antoni Jordan as a historian of the newest Polish philosophy In his article, the author presents Zbigniew Jordan’s works in the area of the history of philosophy, which are not well known in Poland. This representative of Lvov and Warsaw School was abroad, writing his habilitation thesis, when the World War II broke out. The war did not prevent him from active participation in the political life of Polish emigrants in Great (...) Britain. For the needs of current political activity he accomplished a lot of reliable and objective analyses of some geopolitical phenomena, which were a consequence of just finished war. Such kind of works made him take up serious historical studies and he started to use obtained experience to analyze the state and works of modern Polish philosophy, and especially the works of Lvov and Warsaw School. Furthermore, the article is an attempt to show the significance of Jordan’s works in propagating the history of Polish philosophy abroad. (shrink)

This book treats ancient logic: the logic that originated in Greece by Aristotle and the Stoics, mainly in the hundred year period beginning about 350 BCE. Ancient logic was never completely ignored by modern logic from its Boolean origin in the middle 1800s: it was prominent in Boole’s writings and it was mentioned by Frege and by Hilbert. Nevertheless, the first century of mathematical logic did not take it seriously enough to study the ancient logic texts. A renaissance in ancient (...) logic studies occurred in the early 1950s with the publication of the landmark Aristotle’s Syllogistic by Jan Łukasiewicz, Oxford UP 1951, 2nd ed. 1957. Despite its title, it treats the logic of the Stoics as well as that of Aristotle. Łukasiewicz was a distinguished mathematical logician. He had created many-valued logic and the parenthesis-free prefix notation known as Polish notation. He co-authored with Alfred Tarski’s an important paper on metatheory of propositional logic and he was one of Tarski’s the three main teachers at the University of Warsaw. Łukasiewicz’s stature was just short of that of the giants: Aristotle, Boole, Frege, Tarski and Gödel. No mathematical logician of his caliber had ever before quoted the actual teachings of ancient logicians. -/- Not only did Łukasiewicz inject fresh hypotheses, new concepts, and imaginative modern perspectives into the field, his enormous prestige and that of the Warsaw School of Logic reflected on the whole field of ancient logic studies. Suddenly, this previously somewhat dormant and obscure field became active and gained in respectability and importance in the eyes of logicians, mathematicians, linguists, analytic philosophers, and historians. Next to Aristotle himself and perhaps the Stoic logician Chrysippus, Łukasiewicz is the most prominent figure in ancient logic studies. A huge literature traces its origins to Łukasiewicz. -/- This Ancient Logic and Its Modern Interpretations, is based on the 1973 Buffalo Symposium on Modernist Interpretations of Ancient Logic, the first conference devoted entirely to critical assessment of the state of ancient logic studies.

This paper challenges the first Gettier counterexample to the tripartite account of knowledge. Noting that 'the man who will get the job' is a description and invoking Donnellan's distinction between their 'referential' and 'attributive' uses, I argue that Smith does not actually believe that the man who will get the job has ten coins in his pocket. Smith's ignorance about who will get the job shows that the belief cannot be understood referentially, his ignorance of the coins in his pocket (...) shows that it cannot be understood attributively. An explanation for why Smith appeared to have justified true belief is given by distinguishing between 'belief' and 'belief in truth'. Smith believes the sentence 'the man who will get the job has ten coins in his pocket' to be true (he mistakenly believes that Jones will get the job, of whom he knows that he has ten coins in his pocket) (hence his 'belief'), the sentence is true (hence 'truth'), and he has sufficient reason to assent to it (hence his 'justification'). But he does not believe the proposition expressed. Hence he does not know it either. (shrink)

The influence of Kasimir Twardowski on modern Polish philosophy is all-pervasive. As is well known, almost all important 20th century Polish philosophers went through the hard training of his courses in Lvov. Twardowski instilled in his students an enduring concern for clarity and rigour. He taught them to regard philosophy as a collaborative effort, a matter of disciplined discussion and argument. And he encouraged them to work together with scientists from other disciplines — above all with psychologists, and also with (...) mathematicians — so that the Lvov school of philosophy would gradually evolve into the Warsaw school of logic.

The author raises the question why Polish philosophy (by which he means Polish analytical philosophy, or the philosophy of the Lvov-Warsaw School) differs so much from what is known as 'Continental philosophy'. He identifies and analyses the following factors which have influenced philosophical developments in Poland: socialism, the connection between philosophy and mathematics, the influence of Austrian philosophy, the peculiar role of K. Twardowski, and Catholicism. The article ends with an appeal for not tolerating irrationalism and relativism in (...) philosophy. (shrink)

This paper reconstructs the American reception of logical positivism in the early 1930s. I argue that Moritz Schlick (who had visiting positions at Stanford and Berkeley between 1929 and 1932) and Herbert Feigl (who visited Harvard in the 1930-31 academic year) played a crucial role in promoting the *Wissenschaftliche Weltauffassung*, years before members of the Vienna Circle, the Berlin Group, and the Lvov-Warsaw school would seek refuge in the United States. Building on archive material from the Wiener Kreis (...) Archiv, the Harvard University Archives, and the Herbert Feigl Papers, as well as a large number of publications in American philosophy journals from the early 1930s, I reconstruct the subtle transformation of the American philosophical landscape in the years immediately preceding the European exodus. I argue that (1) American philosophical discussions about meaning and significance and (2) internal dynamics in the Vienna Circle between 1929 and 1931 significantly impacted the way in which US philosophers came to perceive logical positivism.

A Norwegian translation is here offered of Eugenie Ginsberg’s paper «Zur Husserlschen Lehre von den Ganzen und den Teilen» (in Archiv für systematische Philosophie und Soziologie 32, 1929, 108–120). The paper discusses Husserl’s six theorems from Logical Investigations III, §14. Ginsberg provides new proofs for theorems 1 and 3, and also endorses theorem 5. In contrast, a counter example is given to theorems 2, 4, and 6: However, proofs are supplied for a modified version of these theorems. Furthermore, an additional (...) three theorems are defended based upon Ginsberg’s modified theorems. Also, a brief introduction is given discussing Ginsberg’s pioneering role as part of the Lvov-Warsaw school—in spite of her being murdered by the Nazis in 1942—especially her role as the first commentator on Husserl’s third logical investigations, which is a pioneering work on mereology and ontology; but also her later publication from 1931 where she developed several notions of ontological dependence (for instance foreshadowing the work of Roman Ingarden as well as Kit Fine).

Logical and philosophical literature provides different classifications of reasoning. In the Polish literature on the subject, for instance, there are three popular ones accepted by representatives of the Lvov-Warsaw School: Jan Łukasiewicz, Tadeusz Czeżowski and Kazimierz Ajdukiewicz (Ajdukiewicz in Logika pragmatyczna [Pragmatic Logic]. PWN, Warsaw (1965, 2nd ed. 1974). Translated as: Pragmatic Logic. Reidel & PWN, Dordrecht, 1975). The author of this paper, having modified those classifications, distinguished the following types of reasoning: (1) deductive and (2) non-deductive, (...) and additionally two types of them in each of the two, depending on the manner of combining their premises with the conclusion through the relation of classical logical entailment. Consequently, the four types of reasoning: unilateral deductive (incl. its sub-types: deductive inference and proof), bilateral deductive (incl. complete induction), and reductive (incl. the sub-types: explanation and verification), logically nonvaluable (incl. inference by analogy, statistic inference), correspond to four operators of derivability. They are defined formally on the ground of Tarski’s axiomatic theory of deductive systems, by means of the consequence operation _Cn_ (Tarski in Monatshefte Math Phys 37:361–404, 1930a, C R Soc Sci Lett Vars 23:22–29, 1930b). Also, certain metalogical properties of these operators are given, as well as their relations with Tarski’s consequence operations \(Cn^+\) ( \(Cn^+ = Cn\) ) and dual consequences \(Cn^{-1}\) (Słupecki in Zeszyty Naukowe Uniwersytetu Wrocławskiego Seria B Nr 3:33–40, 1959, Słupecki et al. in Stud Log 29:76–123, 1971, Wybraniec-Skardowska, in: Wybraniec-Skardowska, Bryll (eds) Z badań nad teorią zdań odrzuconych [Studies in the Theory of Rejected Propositions], Series B, Studia i Monografie, Zeszyty Naukowe Wyższej Szkoły Pedagogicznej w Opolu, Opole, 1969), and \(Cn^-\) (Wójcicki in Bull Sect Log 2(2):54–57, 1973)).

The structure of this paper is as follows. My starting point is psychological flexibility (henceforth, PF) as it has been presented in psychology. Here I offer a synthetic view which embraces the most crucial aspects of flexibility, and describes its functional roles and underlying mechanisms. Secondly, I move my attention onto the field of current action theory and discuss two elementary concepts we commonly use when describing our actions: intention and desire. Of course, there are many “theories of desire” and (...) there is no point in trying (nor even the option) to discuss all of them under one heading. To show where the question of PF sneaks into the scene of action theory, I explore the idea of the resistance of desire, as proposed by Timo Airaksinen. The second concept to investigate at this stage is intention. As in the previous case, it is plain that there are plenty of accounts of intentions and there are many roles they play in the phenomenology of action. For the purposes of this paper, we need only something that can be interpreted as an approach to PF. Such an approach can be found in the idea of stability of intention or a plan, discussed famously by Michael Bratman. According to my interpretation, these two ideas, resistance of desire and stability of intention, allow to initially understand some important aspects of PF in action theory. To get a slightly more comprehensive view – and to supplement the outcomes gained on the grounds of the analyses of these two accounts – I introduce, in the third step, the concept of plasticity which comes from the so-called praxiology proposed by Tadeusz Kotarbiński (Lvov-Warsaw School). I try to show how this concept is still feasible and how it may enrich current philosophical accounts of agential flexibility. The strategy behind this stage of the paper is to enrich the Bratmanian approach to psychological stability. The last part of the paper contains some remarks on the philosophical outcome of the interdisciplinary approach to PF. (shrink)

In this paper, a formal theory is presented that describes syntactic and semantic mechanisms of philosophical discourses. They are treated as peculiar language systems possessing deep derivational structures called architectonic forms of philosophical systems, encoded in philosophical mind. Architectonic forms are constituents of more complex structures called architectonic spaces of philosophy. They are understood as formal and algorithmic representations of various philosophical traditions. The formal derivational machinery of a given space determines its class of all possible architectonic forms. Some of (...) them stand under factual historical philosophical systems and they organize processes of doing philosophy within these systems. Many architectonic forms have never been realized in the history of philosophy. The presented theory may be interpreted as falling under Hegel’s paradigm of comprehending cultural texts. This paradigm is enriched and inspired with Propp’s formal, morphological view on texts. The peculiarity of this modification of the Hegel-Propp paradigm consists of the use of algebraic and algorithmic tools of modeling processes of cultural development. To speak metaphorically, the theory is an attempt at the mathematical and logical history of philosophy inspired by the Internet metaphor. And that is why it belongs to the tradition of doing metaphilosophy in The Lvov-Warsaw School, which is continued today mainly by Woleński, Pelc, Perzanowski, and Jadacki. (shrink)

Reism or concretism are the labels for a position in ontology and semantics that is represented by various philosophers. As Kazimierz Ajdukiewicz and Jan Woleński have shown, there are two dimensions with which the abstract expression of reism can be made concrete: The ontological dimension of reism says that only things exist; the semantic dimension of reism says that all concepts must be reduced to concrete terms in order to be meaningful. In this paper we argue for the following two (...) theses: (1) Arthur Schopenhauer has advocated a reistic philosophy of language which says that all concepts must ultimately be based on concrete intuition in order to be meaningful. (2) In his semantics, Schopenhauer developed a theory of logic diagrams that can be interpreted by modern means in order to concretize the abstract position of reism. Thus we are not only enhancing Jan Woleński’s list of well-known reists, but we are also adding a diagrammatic dimension to concretism, represented by Schopenhauer. (shrink)

This is the first English translation of Leon Chwistek’s “Tragedia werbalnej metafizyki,” Kwartalnik Filozoficzny, Vol. X, 1932, 46–76. Chwistek offers a scathing critique of Roman Ingarden’s Das literarische Kunstwerk and of the entire Phenomenology movement. The text also contains many hints at Chwistek’s own philosophical and formal ideas. The book that Chwistek reviews attracted wide attention and was instrumental in winning Ingarden a position as Professor of Philosophy at the University of Lwów in 1933. Chwistek’s alienation from his fellow logicians (...) of the Lvov-Warsaw school is clear from his ridicule of Leśniewski’s project. (shrink)

This Open Access volume is based on the 'Early Carnap in Context’ workshop that took place in Konstanz in 2017 and looks at Rudolf Carnap’s philosophy, documented in his recently released diaries, from a combination of historical, cultural and philosophical perspectives. It enables further evaluation of the diaries and traces newly found interrelationships and their systematic definition. From a cultural and historical point of view, Logical Empiricism and Carnap’s pivotal opus, The Logical Structure of the World, did not evolve in (...) a vacuum. This applies equally in a history of philosophy context as well as under consideration of contemporary historical and cultural influences such as the socio-cultural setting in Vienna and Prague, the correlation between Logical Empiricism and Bauhaus modernism, the connection to the Life Reform Movement or the Youth Movement with its own life philosophy. Pursuing Carnap’s progression on a micro level of history and referring the results back to Carnap’s philosophy is now facilitated by recent access to his Diaries from 1908–1935. These shorthand records, reading lists, travel reports and notes constitute a valuable source for the research of networks and social movements which left their mark on him. (shrink)

The article describes the background of Roman Ingarden's 1922 review of Leon Chwistek's book Wielość rzeczywistości, and the back-and-forth that followed. Despite the differences, the two shared some interesting similarities. Both authors had important ties to the intellectual happenings outside Poland and were not considerd mainstream at home. In the end, however, it is these connections that allowed them to gain recognition. Ingarden, who had been a student of Husserl, became the leading phenomenologist in the postwar Poland. For Chwistek, a (...) painter, philosopher, and logician interested in Russell’s work, such connections meant that he won the competition for a professorship at the university in Lwów over Alfred Tarski. Until recently, Chwistek’s place in Polish logic remains unclear and Ingarden’s interactions with Polish logic and the Vienna Circle have not been investigated extensively. A deeper look at this intellectual fracas between Ingarden and Chwistek helps one in the study of the complicated mesh of alliances within the Lwów-Warsaw School. The article also identifies the origins of the split between phenomenology and the analytic philosophical tradition in Poland. The article is also accompanied by the translations of the reviews.

Who and how revised Marxism in Poland? The simple answer is that it was done by young intellectuals seeing themselves as obligated to social and political activity, eager to participate in the process of the constitution of a new postwar Communist society. Marxism was for them a philosophical world-view and a political program rising hopes for a better socio-economic reality. Revisionists were committed Communists and their attitude toward Marxism was almost religious. Marxism, Promethean and scientific at the same time, was (...) supposed to replace religion, for which the radically secular revisionists saw no place in the new society. (See: Mikołajczyk 2013, p. 44-48) After the shock of 1956 they stuck by the slogan: ’socialism–yes, distortions–no,’ they thought that “Marxist socialism was possible without Leninist political forms, that Communism might be attacked within «the framework of Marxism»,” and they “believed for some time ... that Stalinism was curable in the sense that Communism could be restored or «democratized» without questioning its foundations” (Kolakowski 1978, p. 461). They saw themselves in an elitist way, i.e., as true and devoted Marxists fighting with dogmas, orthodoxy, myths, and unfounded faith both within Marxism-Leninism and outside it. They were willing to accept the position of sectarians, heretics, or apostates. Their political and ideological involvement forced them to attack pre-war but still active Polish philosophers of the Lvov-Warsaw School and other nonMarxist thinkers (Roman Ingarden, Władysław Tatarkiewicz, Stanisław Ossowski), who were classified as “bourgeois thinkers” unable to understand and assimilate Marxism.

Inquiries concerning the theory of imperatives and norms prosecuted in Poland in the 20th century covered practically the whole scope of this theory. In a uniform conceptual scheme, the paper shows main results of this research done mostly within the Lvov-Warsaw School tradition. It begins with presenting the Polish theoreticians’ approach to three correlated theoretical situations containing our preferences (opposed to impulses, decisions and tendencies), accepted values and imposed obligations. The second step is discussing their views on means (...) of verbalising these situations, i.e. by help of imperatives, evaluations and norms (opposed to consultatives, instructions and optatives) correspondingly. The paper is closed with examining the Polish logicians’ trials of reconstruction of imperative-normative argumentation. (shrink)

Abstract The opening section outlines probabilism in the 20th century philosophy and shortly discusses the major accomplishments of Polish probabilist thinkers. A concise characterization of Bayesianism as the major recent form of probabilism follows. It builds upon the core personalist version of Bayesianism towards more objectively oriented versions thereof. The problem of a priori probability is shortly discussed. A tentative characterization of Kazimierz Ajdukiewicz’s standpoint regarding the inductive inference is cast in Bayesian terms. His objections against it presented in Pragmatic (...) Logic are presented. His 1958 paper on justification of non-deductive inference, as amply demonstrated by K. Szaniawski and I. Niiniluoto, extends his earlier Baysian position from 1928 monograph. In the closing section Ajdukiewicz’s standpoint is presented as a characteristically pragmatist and empiricist version of Bayesianism, which remains an unexplored and stimulating position. (shrink)

Zbigniew Jordan (1911–1977) – an outline to philosophical biography The 100th anniversary of Zbigniew Jordan’s birthday, which is coming soon, is an opportunity to remind this forgotten philosopher, classified in the second generation of Lvov and Warsaw School. His complex fortune reflects dilemmas and perplexities of Polish intelligence in the war and post-war times. Jordan, after defending his doctoral thesis in philosophy at Poznań University, continued his studies at Paris Sorbonne. At that time the prepared his postdoctoral thesis (...) on the notion of infinity. His work on this theme was interrupted by the outbreak of the WWII and Jordan participated in operations of Polish Army in the west. After the end of the war he started working in Radio Free Europe, Paris “Culture” and then in the centres of sovietology research in Europe and the United Stated. He has never come back to philosophy and only in the 1960s he undertook research work at English Universities at first as a lecturer and then as a professor of sociology. He died in the USA in 1977. Although Zbigniew Antoni Jordan did not accomplish any crucial discoveries in science, his life story is nearly a symbol of the historical turbulence and dilemmas, which were experienced by Polish intelligence at emigration.

The article aims to determine whether it is possible to build the reliably practiced classical philosophy, understood as a metaphysical research, directed towards the nature of objective reality. The purpose of this kind of philosophizing is knowledge and truth. Moreover, the practice of such philosophizing and its results should meet some of the characteristics of science. The paper establishes a set of conditions that have been imposed on the science of metaphysics by Kazimierz Twardowski. Among the conditions of such philosophizing (...) are anti-dogmatism, criticism, inter-subjectivity of philosophizing and its results, proper epistemic justification of philosophical beliefs, application of the analysis method, rigorous language and reasoning, the use of experience and scientific knowledge. The paper considers these conditions to be correct in most cases and argues that metaphysics can meet them. The existing cases of analytical metaphysics show that metaphysics is possible as a science. Next, the article argues that the late Twardowski failed to substantiate his claim that metaphysical positions which he classified as a world-view philosophy could not be scientifically justified, which could have been possibly done with differentiating ways of understanding what such a scientific justification should be. The article argues that he did not take into account a reductive conception of the metaphysical philosophy, which even though it allows the plurality of metaphysical explanations and does not force anyone to accept one position as the only possible and correct explanation, would have an objective value, if such metaphysics were elaborated indeed.

This article concerns genealogy of ideas from the Marburg school of neo-Kantian philosophy in’s early works in the context of intellectual and educational tendencies in Europe and the Russian Empire at the turn of the 20th century. Yevhen Spektorskyi (1875–1951) is known as a prominent philosopher and lawyer, professor, and the last president at the Saint Volodymyr University. Analyzing his early works, which were strongly connected to his teaching and scientific activities at the law faculty of Warsaw University, (...) the author recognizes several key factors as the reasons for considerable development of the main neo-Kantian ideas of the philosopher. Firstly, Spektorskyi’s research interests were strongly influenced by the intellectual communication with his teacher, professor, and lawyer Oleksandr Blok (1852–1909), whose research was concentrated on the idea of classification of the sciences and its further substantiating. Secondly, we know that at the beginning of 20th century Spektorskyi was on several long-term educational secondments in European educational institutions, which allowed him to immerse into intellectual life of that time. In the article, the author focuses on analysis of Spektorskyi’s published works and unpublished manuscripts of the years 1903–1910. It is clarified that their main issues concern essential notions and arguments of critical idealism and its implications for the procedures of rational argumentation of sciences (mainly, social sciences) by setting ideal goals and clarification of regulative ideas for the social scientists in their research. The article also examines Spektorskyi’s logical structure of critique of the founder of the Marburg school of Neo-Kantianism Hermann Cohen (1842–1918). The critique concerns the development of ethics as “mathematics of natural science” and argues for the creative and productive rethinking of neo-Kantian ideas by Spektorskyi. (shrink)

Climate change and environmental degradation are threatening the existence of humanity. The youth have the potential and capability to play a pivotal role in tackling these challenges. Therefore, the current study aims to examine how school and family environmental education can enhance environmental knowledge, willingness to take action, and pro-environmental behaviors among children and young people. The Bayesian Mindsponge Framework (BMF) analytics was utilized on a nationally representative dataset of 2069 Vietnamese primary, secondary, and high school students. The (...) analysis results suggest that school and family environmental education is beneficial for improving students’ environmental knowledge and willingness to take environmental actions. Notably, the effect of school education is more substantial for cultivating environmental knowledge, whereas family education has a stronger impact on raising students’ willingness than school education. Students with higher levels of environmental knowledge are more likely to conduct pro-environmental behaviors only when they are willing to take environmental actions. If students are unwilling to act, higher environmental knowledge is negatively associated with the likelihood of pro-environmental behavior. Following these findings, we call for coordinated education efforts of schools and families to cultivate students’ eco-surplus culture. The education efforts should be implemented along with exposing students to environmental settings and encouraging them to read environmental books. (shrink)

This study evaluated school quality indicators and teachers job performance in Cross River State. One research question and four null hypotheses were raised following factorial research design. Proportionate random sampling technique was employed in selecting a sample of 1,463 teachers representing 30 percent from a population of 4,878 teachers distributed across 271 public secondary schools in Cross River State. “School Quality Indicators Questionnaire (SQIQ) and Teachers’ Job Performance Questionnaire (TJPQ)” were the instruments used for data collection. Prepared data (...) were analyzed using descriptive statistics; while the null hypotheses were all tested at .05 alpha level using Pearson Product Moment Correlation and Multiple regression analyses as appropriate with the aid of Minitab statistical software v18. Findings revealed that, quality of school facilities, leadership, and supervision jointly accounted for 90.6 percent (Pred. R2 = .9063) of the total variance of teachers’ job performance; there is significant relationship between quality of school facilities (r = .478, p< .05), quality of leadership (r = .928, p< .05) quality of supervision (r = .881, p< .05) respectively with secondary school teachers’ job performance; quality of school facilities, leadership, and supervision have significant composite influence (F=4800.58, p<.05) on secondary school teachers’ job performance; quality of leadership was the highest predictor (t=45.38, p< .05) of teachers’ job performance, followed by quality of school supervision (t = 27.29, p <.05). Based on these findings, conclusions and recommendations were made for improvement. Keywords:. (shrink)

This study assessed school-community relationship and school system effectiveness in secondary schools in Cross River State. Four null hypotheses were formulated accordingly as guide to the study. The study adopted descriptive survey research design. A total of 1,480 academic staff which comprised 271 principals, and 396 vice principals selected through census technique, and 813 teachers selected using simple random sampling technique, were used to elicit data for the study. “School-Community Relationship and Secondary School System Effectiveness Questionnaire (...) (SCRSSSEQ)” was used as instrument for data collection. Collected data were analyzed using descriptive statistics, while the null hypotheses were all tested at .05 level of significance using Pearson Product Moment Correlation with the aid of SPSS version 21. Findings from the study revealed that: parent-teachers’ relationship, school- community use of resources, school-community communication and school-community collaboration are significantly related to secondary school system effectiveness respectively, in Calabar Municipal Area of Cross River State. It was concluded that generally that school community relationship has significant relationship with school system effectiveness respectively. Based on the findings of this study, it was recommended among others that; principals should setup active parents’ teachers’ associations in their schools with leaders of the association comprising of community members and staff of the school. This will serve as a link that binds the school to the community and will create a platform for discussing and settling disputes. (shrink)

School administrators are mandated to take the instructional leadership roles. On this premise, a study assessed the extent of instructional leadership practices of public elementary school administrators in El Salvador City Division, Philippines. Also, it explored their actual practices, challenges encountered, and the ways they overcome the challenges in practicing instructional leadership. It employed a mixed-method research design. It administered the adopted assessment tool on instructional leadership to 15 school administrators and 12 of them were involved in (...) the individual interviews. This was conducted between the last quarter of 2019 and the first quarter of 2020. Descriptive statistics were used to describe the extent of instructional leadership practices. Also, it analyzed the actual practices, the challenges encountered, and the ways of overcoming these challenges using thematic narrative analysis. Results revealed that public school administrators have always practiced the four domains or strands of instructional leadership to a very high extent. Providing the technical assistance, conducting clinical supervision, and innovating teaching and learning emerged as themes of their actual practices. These administrators had encountered challenges in dealing with teachers’ attitudes, conflicting schedules and activities, and teachers’ resistance to changes. They overcome the challenges by trying to meet the competency standards, adapting and modifying the existing programs, contextualizing teaching and learning, and inculcating the value and benefits of class observation. Looking at the findings from the lens of deliberate practice theory, it was concluded that school administrators have indicated they have acquired knowledge and a high level of understanding of their instructional leadership roles. But despite of this, they still met challenges and have tried their best to manage them. This study presented some doable and practical recommendations to the Department of Education (DepEd) and concerned offices which may benefit both the internal and external stakeholders of the schools.

Findings from the study revealed a significant relationship between physical hazard management, psychological management, environmental hazard management, noise hazard management and teachers job effectiveness in terms of punctuality, classroom management, instructional delivery, lesson evaluation, dressing and record keeping respectively. It was generally concluded that, school hazards management has a significant relationship to teachers' job effectiveness in secondary schools. Based on the findings of this study, recommendations were made. (shrink)

John White (2016) defends the UK private school system from the accusation that it allows an unfair form of ‘queue jumping’ in university admissions. He offers two responses to this accusation, one based on considerations of harm, and one based on meritocratic distribution of university places. We will argue that neither response succeeds: the queue-jumping argument remains a powerful case against the private school system in the UK. We begin by briefly outlining the queue-jumping argument (§1), before evaluating (...) White’s no-harm (§2) and meritocracy (§3) arguments. (shrink)

The Pneumatist school of medicine has the distinction of being the only medical school in antiquity named for a belief in a part of a human being. Unlike the Herophileans or the Asclepiadeans, their name does not pick out the founder of the school. Unlike the Dogmatists, Empiricists, or Methodists, their name does not pick out a specific approach to medicine. Instead, the name picks out a belief: the fact that pneuma is of paramount importance, both for (...) explaining health and disease, and for determining treatments for the healthy and sick. In this paper, we re-examine what our sources say about the pneuma of the Pneumatists in order to understand what these physicians thought it was and how it shaped their views on physiology, diagnosis and treatment.

This paper is an attempt to highlight significant developments in the history of philosophy in schools in Australia. We commence by looking at the early years when Laurance Splitter visited the Institute for the Advancement for Philosophy for Children (IAPC). Then we offer an account of the events that led to the formation of what is now the Federation of Australasian Philosophy in Schools Associations (FAPSA), the development and production of a diverse range of curriculum and supporting materials for philosophy (...) in schools, the making of the Australasian journal, and more recent events. Our purpose is to create further interest in exploring this complex and rich history. This will achieve a better understanding of the possible future directions for classroom practice and research.

Teachers encountered numerous challenges posed by the COVID-19 outbreak. Herewith, this study aimed to determine the challenges encountered by Filipino teachers in the new normal and their coping mechanisms. This study employed a qualitative inquiry to determine the challenges encountered and coping mechanisms employed by teachers amid modular instruction, involving 10 teachers from five secondary schools in the Philippines who participated voluntarily. Data were gathered through a written narrative from each participant and were analyzed thematically. Themed findings showed that these (...) teachers are greatly challenged in terms of learning quality transfer, module distribution and retrieval, students’ difficulties in following instruction, power disruption, internet connection, and health risks posed by the pandemic. Nevertheless, these teachers dealt with these difficulties by employing their own coping techniques. Teaching can be challenging and frustrating, especially in these difficult times, but as these teachers demonstrated, everything is possible. Hence, educators must be ready for any situation that may arise. This situation is unlikely to get better anytime soon; instead, teachers will need to adjust to and accept this reality. (shrink)

Selection within the educational domain breeds a special kind of suspicion. Whether it is the absence of transparency in the selection procedure, the observable outcomes of the selection, or the criteria of selection itself, there is much to corroborate the suspicion many have that selection in practice is unfair. And certainly as it concerns primary and secondary education, the principle of educational equity requires that children not have their educational experiences or opportunities determined by their postcode, their ethnic status, first (...) language, or family wealth. Indeed educational opportunities determined by unearned advantage or disadvantage offend against basic notions of fairness. But are public schools even permitted to select their students, and if so, how can selection procedures used by schools be best structured to achieve equitable ends? In this article we delineate, describe, and defend what we believe are the essential features of selection and also why we need to pay equal attention to both the outcomes and the processes leading to those outcomes. Provided the selection is motivated and guided by the right reasons, as well as appropriately monitored, we argue that selection can be equity promoting. (shrink)

School boosters are tax-exempt organizations that engage in fundraising efforts to provide public schools with supplementary resources. This paper argues that prevailing forms of school boosting are defeasibly unjust. Section 1 shows that inequalities in public education funding in the United States violate John Rawls’s two principles of domestic justice. Section 2 argues that prevailing forms of school boosting exacerbate and plausibly perpetuate these injustices. Section 3 then contends that boosting thereby defeasibly violates Rawlsian principles of nonideal (...) theory for rectifying injustice. Thus, boosting should be presumptively either made illegal or substantially reformed. Finally, Section 4 responds to potential objections. (shrink)

As the international momentum of the school effectiveness movement continues, its exponents remain largely impervious to criticism. This paper argues that while they may not readily align themselves with the individualistic aspects of Conservative social philosophy, their methodology necessarily secretes an atomised social ontology. The charge of ideological commitment rests on the fact that the essentially positivist epistemology employed by school effectiveness researchers presupposes an ontology of closed systems and atomistic events. Thus any notion of the structuring of (...) life‐chances is automatically ruled out of court. The reciprocity of social ontology and methodology is explored in order to account for the myopia of the school effectiveness movement. (shrink)

Nietzsche scholars have developed an interest in his use of “thick” moral psychological concepts such as virtues and emotions. This development coincides with a renewed interest among both philosophers and social scientists in virtues, the emotions, and moral psychology more generally. Contemporary work in empirical moral psychology posits contempt and disgust as both basic emotions and moral foundations of normative codes. While virtues can be individuated in various ways, one attractive principle of individuation is to index them to characteristic emotions (...) and the patterns of behavior those emotions motivate. Despite the surge in attention to Nietzsche’s use of emotions, the literature has tended to lump all emotional states together. In this paper, I argue that what Nietzsche calls the pathos of distance is best understood as the virtue associated with both contempt and disgust. I conclude with a discussion of the bleak prospects for a Nietzschean democratic ethos. (shrink)

As Bhaskar (1989:1) argues, we need to take philosophy seriously because it underwrites both what constitutes science and knowledge and which political practices are deemed legitimate. At present, the field of educational research internationally is witnessing a pragmatist trend, whereby practical education research is carried out without reference to ontological and epistemological concerns. For David Reynolds, a leading UK school effectiveness academic, '[p]recisely because we did not waste time on philosophical discussion or on values debates, we made rapid progress' (...) (1998:20). Equally, for Teddlie, '[t]he orientation of many in the US is to do rather than to reflect […] In reality many practitioners are currently interested in what could work at their school […rather…] than in ruminations about social inequalities associated with different socioeconomic classes' (Teddlie and Reynolds 2000:27). The purpose of this chapter is not only to reclaim critical realist social philosophy for educational research, but also to reclaim reality from the positivist and statistical methodology that underpins School Effectiveness Research (SER) and to make clear the difference that realism makes by virtue of its critical explanatory power in unmasking the ideological nature of SER and its adoption by New Labour.

Proactive educational institutions have introduced entrepreneurship education in their curricula to improve the employability of their learners. Using learners as the lens, the aim of this paper was to assess the efficacy of such programmes in the context of South African high schools and taking into consideration the ethnic and income dynamics of such schools. We argue in this paper that entrepreneurial intention should be complemented with other measures such as frequent enterprise visits and school business projects, especially in (...) the context of junior learners. Purposive sampling was used to select the schools for the case study. Learners (N=403) were drawn from high, medium and low-income schools for the study. Quantifying and non-quantifying data analysis methods were used to interpret the data. Descriptive and inferential statistical techniques were implored to analyse the survey data. The data set was subjected to chi-square tests and multivariate analysis using the SPSS software. It was revealed that an overwhelming majority (62%) of the respondents indicated that they would like to start up a business after their studies. Of these numbers, the overwhelming majority (81%) were black learners. It is also worth noting that a significant proportion (73%) of those that want to become entrepreneurs actually came from the middle income schools. (shrink)
