As the 19th century drew to a close, logicians formalized an ideal notion of proof. They were driven by nothing other than an abiding interest in truth, and their proofs were as ethereal as the mind of God. Yet within decades these mathematical abstractions were realized by the hand of man, in the digital stored-program computer. How it came to be recognized that proofs and programs are the same thing is a story that spans a century, a (...) chase with as many twists and turns as a thriller. At the end of the story is a new principle for designing programming languages that will guide computers into the 21st century. -/- For my money, Gentzen’s natural deduction and Church’s lambda calculus are on a par with Einstein’s relativity and Dirac’s quantum physics for elegance and insight. And the maths are a lot simpler. I want to show you the essence of these ideas. I’ll need a few symbols, but not too many, and I’ll explain as I go along. -/- To simplify, I’ll present the story as we understand it now, with some asides to fill in the history. First, I’ll introduce Gentzen’s natural deduction, a formalism for proofs. Next, I’ll introduce Church’s lambda calculus, a formalism for programs. Then I’ll explain why proofs and programs are really the same thing, and how simplifying a proof corresponds to executing a program. Finally, I’ll conclude with a look at how these principles are being applied to design a new generation of programming languages, particularly mobile code for the Internet. (shrink)

A brief overview of the main Croatian philosophers of the 19th century is given (regardless of whether they worked in or outside of Croatia). Special attention is paid to Šimun Čučić (logic, metaphysics, ethics) and Franjo pl. Marković (logic, aesthetics). The philosophy of other authors is briefly summarized on the ground of the existing research results.

This chapter explores interpretive debates about Aristotle’s Categories in the 19th century. The interpretation of this text became the locus to pursue the further philosophical aim of defending logic against an epistemological recalibration of concepts such as that found in the transcendental and metaphysical deductions of Kant’s Critique of Pure Reason. As Colin Guthrie King argues, this was the ultimate philosophical ambition of Friedrich Adolf Trendelenburg’s interpretation of Aristotle’s doctrine of categories, but perhaps more important than this (...) project itself were its derivatives: a model for the proper philosophical interpretation of an ancient philosophical text, and an exemplary model of how to defend such a text against an influential anachronistic interpretation.

The first beginnings of modern logic in Croatia are recognizable as early as in the middle of the 19th century in Vatroslav Bertić. At the turn of the 20th century, Albin Nagy, who was teaching in Italy, made contributions to algebraic logic and to the philosophy of logic. At that time, a distinctive author Mate Meršić stood out, also working on algebraic logic. In the Croatian academic philosophy, until the publication of Gajo Petrović's (...) textbook (1964) and the contributions by Heda Festini, a critical or indifferent attitude toward modern logic prevailed. The first comprehensive modern logic textbook in Croatian was written by mathematician Vladimir Devidé (1964), known, for example, for his axiomatizations of natural numbers and classical propositional logic. In the Croatian philosophy of the 1980s and 1990s, influential logicians are Goran Švob and mathematician Zvonimir Šikić. At the turn of the 21st century, logical investigations are being intensified and extended to various branches of the contemporary logic. (shrink)

In their paper ‘Why Frege did not plagiarize the Stoics’ (Gabriel et al. 2024), G. Gabriel, K. Hülser and D. Rami provide an extended set of arguments to show that Frege didn’t, and couldn’t have, plagiarize(d) the Stoics via Prantl’s long chapter on Stoic logic (Prantl 1855) or at all, thus attempting to counter Bobzien’s 2021 ‘Frege plagiarized the Stoics’. The present short essay is Part II of a four-part refutation of Gabriel et al. 2024: The authors repeatedly ‒ (...) and wrongly ‒ claim that there is a tradition of Stoic logic (and Stoic logical terminology) transmitted continuously from antiquity to the 19th century that was generally known in the 18th and 19th centuries. In this second part of the refutation, it is shown that, and why, the authors are entirely mistaken on every one of these points. (shrink)

The debate about Aristotle’s categories in the 19th century is largely a reaction to Kant’s criticisms of the Aristotelian theory of categories. Scholars tried both to interpret Aristotle’s texts and to defend the Stagirite from the accusation of collecting the categories in a rhapsodic way. Starting from this well-known historiographical assumption, I aim to show that Kant not only criticized but also provided an interpretation of the Aristotelian theory of categories and that the interpretations of nineteenth-century scholars (...) (Trendelenburg, Bonitz, Brentano, Apelt, and others), while intending to respond to Kant, move largely within the conceptual framework outlined by Kant, contain Kantian elements or develop hints provided by Kant.

In this extended essay, I argue that Frege plagiarized the Stoics --and I mean exactly that-- on a large scale in his work on the philosophy of logic and language as written mainly between 1890 and his death in 1925 (much of which published posthumously) and possibly earlier. I use ‘plagiarize' (or 'plagiarise’) merely as a descriptive term. The essay is not concerned with finger pointing or casting moral judgement. The point is rather to demonstrate carefully by means of (...) detailed evidence that there are numerous (over a hundred) and extensive parallels both in formulation and --more importantly-- in content between the Stoics and Frege, parallels so plentiful that one would be hard pressed to brush them off as coincidence. These parallels include several that appear to occur in no other modern works that were published before Frege’s own and were accessible to him. Additionally, a cluster of corroborating historical data is adduced to support the suggestion, showing how easy it would have to been for Frege to plagiarize the Stoics. This (first) part of the essay is easy to read and vaguely entertaining, or so I hope. (Corrigendum: At school, Frege likely had seven, not ten, years of intensive Latin and four years of intensive ancient Greek courses.). (shrink)

Bertrand Russell was one of the best-known proponents of logicism: the theory that mathematics reduces to, or is an extension of, logic. Russell argued for this thesis in his 1903 The Principles of Mathematics and attempted to demonstrate it formally in Principia Mathematica (PM 1910–1913; with A. N. Whitehead). Russell later described his work as a further “regressive” step in understanding the foundations of mathematics made possible by the late 19th century “arithmetization” of mathematics and Frege’s logical (...) definitions of arithmetical concepts. The logical system of PM sought to improve on earlier attempts by solving the contradictions found in, e.g., Frege’s system, by employing a theory of types. In this article, I also consider and critically evaluate the most common objections to Russell’s logicism, including the claim that it is undermined by Gödel’s incompleteness results, and Putnam's charge of “if-thenism”. I suggest that if we are willing to accept a slightly revisionist account of what counts as a mathematical truth, these criticisms do not obviously refute Russell’s claim to have established that mathematical truths generally are a species of logical truth.

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

Logic diagrams have seen a resurgence in their application in a range of fields, including logic, biology, media science, computer science and philosophy. Consequently, understanding the history and philosophy of these diagrams has become crucial. As many current diagrammatic systems in logic are based on ideas that originated in the 18th and 19th centuries, it is important to consider what motivated the use of logic diagrams in the past and whether these reasons are still valid (...) today. This paper proposes that transcendental philosophy was a key inspiration for the development of logic diagrams and that such diagrams can be employed in transcendental arguments, even after the linguistic turn.

Renaissance philosopher, mathematician, and theologian Nicholas of Cusa (1401-1464) said that there is no proportion between the finite mind and the infinite. He is fond of saying reason cannot fully comprehend the infinite. That our best hope for attaining a vision and understanding of infinite things is by mathematics and by the use of contemplating symbols, which help us grasp "the absolute infinite". By the late 19th century, there is a decisive intervention in mathematics and its philosophy: the (...) philosophical mathematician Georg Cantor (1845-1918) says that between the realm of the finite and the absolute infinite, there is an intermediate realm partaking in properties in a certain sense of both the finite and the infinite: the transfinite realm. Like the finite, the transfinite realm is a realm of mathematical objects, numbers, and knowledge. Like the absolute infinite, the transfinite is a form of infinity insofar as transfinite sets and numbers transcend any finite number. Echoing Cusanus and neo-Platonism, Cantor says that the transfinite sequence of all ordinals is a symbol of the absolutely infinite, that is, God. This paper considers how the doctrine of symbolism and the philosophers' different commitments to the laws of logic, especially the Law of Non-Contradiction (LNC), enables these thinkers to articulate a transcendental apophatic approach to divinity.

This volume examines the entire logical and philosophical production of Nikolai A. Vasil’ev, studying his life and activities as a historian and man of letters. Readers will gain a comprehensive understanding of this influential Russian logician, philosopher, psychologist, and poet. The author frames Vasil’ev’s work within its historical and cultural context. He takes into consideration both the situation of logic in Russia and the state of logic in Western Europe, from the end of the 19th century (...) to the beginning of the 20th. Following this, the book considers the attempts to develop non-Aristotelian logics or ideas that present affinities with imaginary logic. It then looks at the contribution of traditional logic in elaborating non-classical ideas. This logic allows the author to deal with incomplete objects just as imaginary logic does with contradictory ones. Both logics are objects of interesting analysis by modern researchers. (shrink)

Modern logic is primarily concerned with formally valid arguments, namely arguments where the conclusion is a logical consequence of the premises. Intuitively, this means that the conclusion necessarily follows from the premises in virtue of their logical form alone. Such arguments form the backbone of philosophy, mathematics, and science in general: for instance, the famous Pythagorean Theorem is a logical consequence of the axioms of Euclidean geometry. However, the task of defining the concept of logical consequence is far from (...) straightforward. Logical consequence is the glue that holds our belief system together, but what holds the glue together? This question cuts deep into the very foundations of scientific knowledge. -/- The standard model-theoretic definition of logical consequence, originally formulated by Alfred Tarski in 1936, has been questioned by philosophers from various perspectives over the past few decades. John Etchemendy famously argues that Tarski’s account fails to capture the pre-theoretic, intuitive concept of logical consequence. Logical pluralists suggest that there is more than one correct concept of it. On the other hand, historians have pointed out that Tarskian definitions of logical consequence had already been proposed by Parisian logicians in the 14th century, and again by Bernard Bolzano in the 19th century. It has been suggested that their proposals may have captured the intuitive concept of logical consequence even better than Tarski’s. And yet, the fact that their proposals were not widely accepted at their own time suggests that the intuitive concept itself may have changed over time. -/- The aim of this dissertation is to analyse the continuities and discontinuities between Tarski’s account and its premodern precedents. My overall thesis is twofold. On one hand, I show that a Tarskian ‘substitutional’ criterion of logical consequence was more widespread in the 14th century than has been previously thought, and that it continued to be promoted by many prominent textbooks of logic in the early modern era until it was subsumed by the Aristotelian theory of the syllogism. On the other hand, I argue that the notion of logical form presupposed by most 14th-century authors was distinctively non-Tarskian. Back then, logical form was primarily about relationships among concepts, but it is now taken to be just about the structural properties of propositions. I suggest that Tarski is partly to blame for this transformation: his definition was successful precisely because he deliberately suppressed some philosophical intuitions to suit the needs of mathematical logicians. -/- The dissertation consists of five articles. Article I focuses on the theories of formal consequence by the 14th-century logician William of Ockham and his student Adam Wodeham. Both distinguished between two kinds of formal consequence (consequentia formalis), the first of which anticipates Tarski’s account, but their second kinds of formal consequence differ. I show that Wodeham’s two kinds of formal consequence are based on two kinds of logical form. -/- In Article II, I further develop and defend what I call the ‘dual form hypothesis’. I ask why the 14th-century Parisian tradition of formal consequence, as close as it is to Tarski’s definiton, was not as influential at the time as the rival British tradition. I argue that the two traditions were closer to each other than we have thought. They agreed that formal consequence involves a truth-preserving form, and only disagreed on whether that form is structural or conceptual. -/- Article III traces the early modern reception of the Parisian definition through a large-scale analysis of Early English Books Online, which contains almost all books printed in the British empire from the 15th to the 17th century. I show that Parisian-style definitions were surprisingly widespread in textbooks of logic that were used for teaching in Oxford, Cambridge, and Dublin for a long time. -/- In Article IV, I argue that Tarski’s definition of logical consequence is not a conceptual analysis (as Etchemendy and others have claimed) but a Carnapian explication. The point is that Tarski did not even try to capture the essence of a pre-existing everyday concept; on the contrary, he deliberately sacrificed some everyday intuitions on the altar of formal correctness. -/- Finally, Article V takes on the challenge of formalizing the medieval British definition of formal consequence in modern logic. I try out several approaches and conclude that Gillian Russell’s recent account of logical consequence can be applied to provide a fruitful formalization of the medieval notion. (shrink)

Biosemiotics belongs to a class of approaches that provide mental models of life since it applies some semiotic concepts in the explanation of natural phenomena. Such approaches are typically open to anthropomorphic errors. Usually, the main source of such errors is the excessive vagueness of the semiotic concepts used. If the goal of biosemiotics is to be accepted as a science and not as a priori metaphysics, it needs both an appropriate source of the semiotic concepts and a reliable method (...) of adjusting them for biosemiotic use. Charles S. Peirce’s philosophy offers a plausible candidate for both these needs. Biosemioticians have adopted not only Peirce’s semiotic concepts but also a number of metaphysical ones. It is shown that the application of Peirce’s basic semiotic conceptions of sign and sign-process (semiosis) at the substantial level of biosemiotics requires the acceptance of certain metaphysical conceptions, i.e. Tychism and Synechism. Peirce’s method of pragmaticism is of great relevance to biosemiotics: 1. Independently of whether Peirce’s concepts are used or even applicable at the substantial level of biosemiotics, Peirce’s method remains valuable in making biosemiotics and especially in adjusting its basic concepts. 2. If Peircean semeiotic or metaphysics is applied at the substantial level of biosemiotics, pragmaticism is valuable in clarifying the meaning and reference of the applied Peircean concepts. As a consequence, some restrictions for the application of Peirce in biosemiotics are considered and the distinction of Peirce’s philosophy from the 19th century idealistic Naturphilosophie is emphasized.

The emergence of the entropy-as-disorder metaphor in the 19th century is considered. The logic behind the emergence of the metaphor of negative entropy in Schrödinger’s book is presented. After that the irrelevance of the entropy-as-disorder metaphor as well as the negative entropy metaphor is discussed. An alternative metaphor based on the concept of free energy is proposed.

By the beginning of the 19th century Hegel's dialectic turned contradiction (conceived as unity of a concept with its determined negation) into distinguished inference. In the course of 20th century a family of systems known as "paraconsistent" formalized dialectical logic according to the contemporary paradigm of inference, oriented to truth-preserving, and not powered anymore solely by contradiction. In this way, nevertheless, Hegel's idea of logic as unfolding of concepts ordered by degree of "determination" reached at (...) every step of the process, was put aside. We attempt to recover the importance of that idea for the hegelian concept of "logical necessity", pointing out in addition that it may well play the role of an order relation for dialectical inference.

This paper addresses a structural question at the intersection of philosophy and science: why has the constitutional layer of theoretical systems remained institutionally vacant since the late 19th century, and what are the formal consequences of this vacancy? -/- We introduce a functional distinction between two layers present in any theoretical construction. The operational layer executes inference, computation, and expansion. The constitutional layer specifies what a theory is, within what scope it is valid, and what identity criteria it (...) adopts. Historical analysis from 1870 to 2000 demonstrates that the divergence of mathematical physics from philosophical methodology produced an institutional separation in which the constitutional layer was systematically left without an explicit custodian. -/- The central formal result, the Internal Closure Impossibility Theorem, proves that no operational layer can generate its own constitutive conditions as internal operations. The proof proceeds by reductio ad absurdum: assuming such internal generation exists produces an infinite regress that cannot terminate within finite computational resources. An external fixation point, termed Arbitrium, is therefore structurally necessary. -/- This result is not a reformulation of Gödel incompleteness or Tarski's truth hierarchy. Gödel operates at the syntactic level of formal systems; Tarski at the level of linguistic hierarchies. The present theorem operates at the constitutive level of theoretical construction itself. -/- The framework employed is Noology, a formal system developed within Cognitional Mechanics, which provides axiomatic foundations for the functional separation of constitutional and operational layers. Re-implementing the audit function in a form compatible with contemporary mathematical physics constitutes the logical responsibility identified by this paper. (shrink)

马克思主义自19世纪提出以来，对人类社会的政治、经济、生态和精神文明产生了深远影响。然而，其理论与实践在多维度上存在系统性危害：政治上导致极权统治与阶级斗争逻辑，经济上忽视自然与生态循环，生态上造成环 境破坏与资源枯竭，精神文明上压制创新与文化自由。本文通过历史案例分析（苏联、中国、古巴等国），结合“老-杨创世纪宇宙观”的自然生成、循环共生哲学，对马克思主义实践的深层危害进行系统剖析，并提出面向未来 文明的重建路径：政治自由与平衡、经济可持续发展、生态共生、精神文明创新，以及多维度整合的系统性自我调节机制。最终指出，文明的发展必须遵循宇宙法则，顺应自然生成与共生原则，实现社会、文明与自然的长期和谐 。 -/- Abstract Since its inception in the 19th century, Marxism has profoundly influenced human society in political, economic, ecological, and cultural dimensions. However, both its theory and practice have produced systematic harms: politically, it leads to authoritarian rule and class struggle logic; economically, it disregards natural and ecological cycles; ecologically, it results in environmental degradation and resource depletion; culturally and spiritually, it suppresses innovation and freedom. Through historical case studies (e.g., the Soviet Union, China, Cuba) and (...) in the perspective of the Lao-Yang Genesis Cosmology, which emphasizes natural generation, cyclicality, and symbiosis, this paper systematically analyzes the deep harms of Marxist practice and proposes pathways for reconstructing future civilization: political freedom and balance, sustainable economic development, ecological symbiosis, cultural and spiritual innovation, and multi-dimensional systemic self-regulation. It ultimately argues that civilization must follow universal cosmic laws, harmonize with natural generation and symbiosis, and achieve long-term societal, civilizational, and ecological equilibrium. -/- .

The reception of Kant began in Croatia at the turn of the 19th century with the writings of J.B. Horváth, whose textbooks were in use at that time in Croatia and Hungary. Unlike Horváth's decidedly negative attitude toward Kant, Šimun Čučić (Simeon Chuchich), in his systematic work Philosophia Critice Elaborata (1815), adopted some aspects of Kantian philosophy. This includes, for example, the formalistic conception of logic, Kantian apriorism and subjectivism, the formalistic approach to the moral law, and (...) the like. However, since these elements were incorporated into a schoolbook type of text, they could not always be consistently implemented. The beginning of the reception of Kant in Croatia coincided with the revival of Croatian national self-awareness. -- Die Kantrezeption setzte in Kroatien an der Wende zum 19. Jahrhundert ein mit den Schriften J. B. Horváths, dessen Lehrbuecher in Kroatien und Ungarn damals in Gebrauch waren.

Quine’s classical classic interpretation succinctly characterized characterizes Carnap’s Aufbau as an attempt “to account for the external world as a logical construct of sense-data....” Consequently, “Russell” was characterized as the most important influence on the Aufbau. Those times have passed. Formulating a comprehensive and balanced interpretation of the Aufbau has turned out to be a difficult task and one that must take into account several disjointed sources. My thesis is that the core of the Aufbau rested on a problem that (...) had haunted German philosophy since the end of the 19th century. In terms fashionable at the time, this problem may be expressed as the polarity between Leben and Geist that characterized German philosophy during the years of the Weimar Republic. At that time, many philosophers, including Cassirer, Rickert and Vaihinger, were engaged in overcoming this polarity. As I will show, Carnap’s Aufbau joined the ranks of these projects. This suggests that Lebensphilosophie and Rickert’s System der Philosophie exerted a strong influence on Carnap’s projects, an influence that is particularly conspicuous in his unpublished manuscript Vom Chaos zur Wirklichkeit. Carnap himself asserted that this manuscript could be considered “the germ of the constitution theory” of the Aufbau. Reading Chaos also reveals another strong but neglected influence on the Aufbau, namely a specific version of neutral monism put forward by the philosopher and psychologist Theodor Ziehen before World War I. Ziehen’s work contributed much to the invention of the constitutional method of quasi-analysis. -/-. (shrink)

With his influence on the development of physiology, physics and geometry, Hermann von Helmholtz – like few scientists of the second half of the 19th century – is representative of the research in natural science in Germany. The development of his understanding of science is not less representative. Until the late sixties, he emphatically claimed the truth of science; later on, he began to see the conditions for the validity of scientific knowledge in relative terms, and this can, (...) in summary, be referred to as hypothesizing. Already in the past century, HeImholtz made first approaches to an understanding of science, which were incompatible with his own former position and which pointed to the modern age to an astonishingly large extent. A comparison with Karl R. Popper's logic of research will illustrate how closely he nevertheless approached modern understanding of science. In Popper's logic of research, hypothesizing of scientific knowledge is definitely much more advanced than in Helmholtz's theory of science. What begins vaguely to emerge with Helmholtz has already become an explicitly formulated programme with Popper. Although HeImholtz and Popper are not on a direct line of epistemological development and Popper refers to HeImholtz only rarely and casually, there are in fact surprising points of contact which have not been taken notice of so far and which appear above all if one looks at Helmholtz's understanding of science against the background of Popper's logic of research.

The question of the applicability of mathematics is an epistemological issue that was explicitly raised by Kant, and which has played different roles in the works of neo-Kantian philosophers, before becoming an essential issue in early analytic philosophy. This paper will first distinguish three main issues that are related to the application of mathematics: indispensability arguments that are aimed at justifying mathematics itself; philosophical justifications of the successful application of mathematics to scientific theories; and discussions on the application of real (...) numbers to the measurement of physical magnitudes. A refinement of this tripartition is suggested and supported by a historical investigation of the differences between Kant’s position on the problem, several neo-Kantian perspectives, early analytic philosophy, and late 19th century mathematicians. Finally, the debate on the cogency of an application constraint in the definition of real numbers is discussed in relation to a contemporary debate in neo-logicism, in order to suggest a comparison not only with Frege’s original positions, but also with the ideas of several neo-Kantian scholars, including Hölder, Cassirer, and Helmholtz.

-/- Populism: A Double-Edged Sword in Modern Democracy -/- Populism is one of the most frequently used yet often misunderstood terms in contemporary political discourse. It has influenced elections, swayed public opinion, and reshaped national policies across the globe. At its core, populism is a political strategy or approach that aims to represent the interests and voice of the “common people” in opposition to a perceived corrupt elite or establishment. While it can reinvigorate democracy and bring neglected issues to the (...) forefront, populism also poses significant risks to democratic institutions and social cohesion. -/- Defining Populism -/- Populism does not function as a comprehensive ideology like conservatism or socialism. Rather, it operates as a political logic or style, often characterized by a dichotomy between “the pure people” and “the corrupt elite” (Mudde & Rovira Kaltwasser, 2017). Populist leaders claim to embody the general will of the people and typically frame their opposition as illegitimate or morally inferior. This approach often involves direct appeals to the masses, with disdain for traditional institutions like the judiciary, media, or political parties. -/- Populism can manifest across the ideological spectrum. Left-wing populism tends to focus on economic justice, inequality, and class struggle, while right-wing populism often emphasizes nationalism, cultural identity, and skepticism toward immigration or globalism. Regardless of political leaning, populism fundamentally seeks to mobilize people against established centers of power. -/- Historical Origins and Global Spread -/- The term “populism” originated from the U.S. People’s Party in the late 19th century. This movement represented the grievances of rural farmers against banks, railroads, and industrial monopolies (Kazin, 1995). Populism later gained prominence in Latin America through leaders like Juan Perón in Argentina and Hugo Chávez in Venezuela, who blended charismatic leadership with policies aimed at empowering the poor and working class. -/- In the 21st century, populism has reemerged as a powerful force globally. In Europe, populist parties have capitalized on discontent stemming from economic crises, refugee influxes, and dissatisfaction with the European Union. In Asia and Africa, populist leaders have gained popularity by challenging colonial legacies, elite corruption, and foreign influence, often promising national revival and self-sufficiency. Populist movements have also gained traction in North America, where distrust in traditional political systems continues to grow. -/- The Appeal of Populism -/- Populism thrives in environments of crisis, inequality, and mistrust. Economic instability, unemployment, cultural change, and political disillusionment create fertile ground for populist narratives (Inglehart & Norris, 2016). Populist leaders offer clear, emotionally resonant messages that speak directly to people’s fears, frustrations, and hopes. -/- The modern media landscape, particularly the rise of social media, has intensified the populist surge. Populist figures often bypass traditional media outlets to communicate directly with their supporters, spreading simple, relatable messages that may resonate more than complex policy debates (Moffitt, 2016). This direct connection fosters a sense of authenticity and responsiveness, further building trust among followers. -/- Criticisms and Dangers -/- Despite its potential to increase democratic engagement, populism carries several risks. First, by dividing society into binary opposites—good versus evil, people versus elite—it tends to polarize the political landscape. This can lead to the erosion of democratic dialogue, compromise, and mutual respect. -/- Second, populist leaders often challenge the legitimacy of democratic institutions. By attacking the press, judiciary, or electoral processes, they may consolidate power and undermine checks and balances (Levitsky & Ziblatt, 2018). Some populist regimes have curtailed civil liberties, weakened the rule of law, or manipulated elections under the guise of fulfilling the people’s will. -/- Third, populism can result in unrealistic promises and short-term policies. Leaders may appeal to emotional grievances without addressing underlying structural problems. When results fail to materialize, disillusionment can set in, potentially fostering instability or extremism. -/- Feasible Solutions -/- To mitigate the dangers of populism while addressing its root causes, a multi-pronged approach is essential: -/- 1. Strengthen Democratic Institutions: Governments should reinforce the independence and credibility of democratic institutions—such as courts, electoral commissions, and public broadcasters. Transparent, accountable institutions build public trust and can resist manipulation by populist actors. -/- 2. Promote Inclusive Economic Policies: Economic inequality fuels populist discontent. Policymakers should implement inclusive policies that promote equitable access to jobs, education, and healthcare. Investment in rural areas and marginalized communities can reduce the perception of systemic neglect. -/- 3. Improve Political Communication and Civic Education: Citizens need to understand how democracy functions and how their participation matters. Educational systems should promote critical thinking, media literacy, and awareness of democratic norms to make citizens more resistant to demagoguery and misinformation. -/- 4. Address Legitimate Grievances Responsibly: Rather than dismissing populist concerns outright, mainstream parties and institutions should listen to citizens’ real frustrations—whether they stem from globalization, immigration, or corruption—and address them through practical and evidence-based policy solutions. -/- 5. Encourage Transparent and Ethical Leadership: Ethical governance, anti-corruption measures, and public accountability are key to countering the appeal of populists who promise to “clean up the system.” Leaders must lead by example to restore faith in politics. -/- 6. Foster Social Dialogue and Unity: Building platforms for dialogue between different social, ethnic, and political groups can reduce polarization. Promoting mutual understanding and cooperation, especially at the local level, fosters social cohesion and resilience against divisive rhetoric. -/- Conclusion -/- Populism is a complex and dynamic force in modern democracy. It reflects genuine grievances and has the capacity to rejuvenate political engagement. However, it also poses serious risks if it erodes democratic norms, institutions, and societal unity. The challenge for democratic societies is to respond constructively: by listening, reforming, and educating—rather than by repressing or ignoring. -/- If the root causes of populism are addressed with empathy, transparency, and sound policy, its energy can be redirected into positive democratic renewal rather than destructive division. Only through this balanced approach can democracies survive and thrive in an age of uncertainty and change. -/- References -/- Inglehart, R., & Norris, P. (2016).

The mathematical developments of the 19th century seemed to undermine Kant’s philosophy. Non-Euclidean geometries challenged Kant’s view that there is a spatial intuition rich enough to yield the truth of Euclidean geometry. Similarly, advancements in algebra challenged the view that temporal intuition provides a foundation for both it and arithmetic. Mathematics seemed increasingly detached from experience as well as its form; moreover, with advances in symbolic logic, mathematical inference also seemed independent of intuition. This paper considers various (...) philosophical responses to these changes, focusing on the idea of modifying Kant’s conception of intuition in order to accommodate the increasing abstractness of mathematics. It is argued that far from clinging to an outdated paradigm, programs based on new conceptions of intuition should be seen as motivated by important philosophical desiderata, such as the truth, apriority, distinctiveness and autonomy of mathematics.

Why did Kierkegaard prefer to write his masterpieces under different pseudonyms and what was the theatrical logic behind the constant playfulness of an author otherwise doomed to melancholy? What were the reasons of his ongoing philosophical, theological and aesthetic hide-and-seek that he did not want to finish until the very last, nearly tragic phase of his authorship? How much inspiration did Kierkegaard receive from theatrical performances, from playwrights and even from actors and actresses of 19th-century Copenhagen, which (...) seemed to be sometimes stronger than the influence exercised on him by his professors, masters and theologians of Denmark’s “Golden Age”? Can the difference between direct and indirect communication that basically characterized Kierkegaard’s oeuvre be described in theatrical terms or even to approach it as an ongoing dramatic dialogue? Should we rather call it a “polylogue” as different actors are present throughout the texts that were often polemic with each other, simultaneously reflecting certain issues from different angles and finally Kierkegaard denying that any of those were written by him? Could his own name be a pseudonym, as his brother suggested when giving the eulogy on the prodigal son, who learned to doubt from Socrates and from Descartes, yet could not give up his intention to question even the final axioms of human existence? The author tries to find answers to these questions by reconstructing the very special Kierkegaardian method, so familiar from the stage, in the spiritual, cultural and theatrical context of Kierkegaard’s Denmark.

Kant’s account of objective knowledge famously uses a dualism of types of representation: intuitions and concepts. This dualism came under renewed criticism from many of his followers. By eliminating intuition, the a priori judgements of mathematics were no longer viewed as requiring syntheses. This means that mathematical knowledge had to be analytic. As a result, its derivability from logic became a major focus of interest at the end of the 19th century. Frege’s proposal for this logicist programme (...) however led to a paradox identified by Russell. This paper claims that this can be seen as a direct consequence of the discarding of intuition in epistemology. The paper proposes a Kantian solution to the paradox, and offers a diagnosis which identifies in what sense this paradox can be viewed as an antinomy. In this way, the paper seeks to illustrate the scope of the Kantian conception of antinomy against a background of post-Kantian developments in logic. (shrink)

GILBERT JEAN FACCARELLO (Paris, 1950) is professor of economics at Université Panthéon-Assas, Paris, and a member of the Triangle research centre (École Normale Supérieure de Lyon and CNRS). He is presently chair of the ESHET Council (European Society for the History of Economic Thought). He completed his doctoral research in economics at Université de Paris X Nanterre. He has previously taught at the Université de Paris-Dauphine, Université du Maine and École Normale Supérieure de Fontenay/Saint-Cloud (now École Normale Supérieure de Lyon). (...) He is a co-founder of The European Journal of the History of Economic Thought, which he co-edited for 20 years with J. L. Cardoso, Heinz D. Kurz, and A. Murphy. With Alain Béraud, he edited the Nouvelle histoire de la pensée économique (La Découverte, 3 volumes, 1992-2000) and, together with Heinz D. Kurz, he is presently editing a Handbook of the History of Economic Analysis (3 volumes, forthcoming with Edward Elgar). -/- EJPE interviewed Gilbert Faccarello about his research career in the history of economic thought, where he has focused especially on old and new classical and Marxian political economy, and French political economy during the 18th and 19th centuries. G. Faccarello discusses his interest not only in the logical structure and context of the economic ideas of past thinkers but also the links between economic thought, philosophy, and religion.

A new, modern interpretation of the term "ideology" is proposed, in which this term is defined as a general philosophical and semantic meaning of the name of an important epistemological method. The polemics contain an indication of the narrow contextual specificity of the first experiments in the use of the term in the works of French philosophers of the 19th century and a different semantic basis. On the example of the practical use of this method, the study defines (...) and formulates the basic features of human intelligence. Based on the practical use of this method, the basic features of human intelligence are determined and formulated in the study. Based on further research into human syntactic perception and syntactically structured human responses to perceptions, we are trying to determine how AI architecture will be organized and whether its work can only be organized taking into account positive, humanitarian goal-setting. Efforts to develop AI based on professional approaches, rather than on an exceptionally narrow vision from the standpoint of the technical implementation of some theoretically unjustified task related to increasing the productivity of individual services and technological processes, are evaluated. The need for ontological research in the philosophy of AI in its ideal form, as it should be, and the definition of its state today is emphasized. Attention is also paid to the logical and semantic definition of the term "artificial intelligence." It has been argued that the term does not capture the ultimate goals or ambitions of this technology industry but is only referred to as such for the purpose of marketing success. The AI models being created in their architectural foundations are proposed to be compared with the basic natural organization of human intelligence. Based on a comparison of the basic elements of human intelligence and AI, the study concludes that they have nothing in common. (shrink)

The philosophy of mathematics has been accused of paying insufficient attention to mathematical practice: one way to cope with the problem, the one we will follow in this paper on extensive magnitudes, is to combine the `history of ideas' and the `philosophy of models' in a logical and epistemological perspective. The history of ideas allows the reconstruction of the theory of extensive magnitudes as a theory of ordered algebraic structures; the philosophy of models allows an investigation into the way epistemology (...) might affect relevant mathematical notions. The article takes two historical examples as a starting point for the investigation of the role of numerical models in the construction of a system of non-Archimedean magnitudes. A brief exposition of the theories developed by Giuseppe Veronese and by Rodolfo Bettazzi at the end of the 19th century will throw new light on the role played by magnitudes and numbers in the development of the concept of a non-Archimedean order. Different ways of introducing non-Archimedean models will be compared and the influence of epistemological models will be evaluated. Particular attention will be devoted to the comparison between the models that oriented Veronese's and Bettazzi's works and the mathematical theories they developed, but also to the analysis of the way epistemological beliefs affected the concepts of continuity and measurement.

Psychology has been considered to have an autonomy from the other sciences (especially physical science) in at least two ways: in its subject-matter and in its methods. To say that the subject-matter of psychology is autonomous is to say that psychology deals with entities—properties, relations, states—which are not dealt with or not wholly explicable in terms of physical (or any other) science. Contrasted with this is the idea that psychology employs a characteristic method of explanation, which is not shared by (...) the other sciences. I shall label the two senses of autonomy ‘metaphysical autonomy’ and ‘explanatory autonomy’ The question of whether psychology as a science is autonomous in either sense is one of the philosophical questions surrounding the (somewhat vague) doctrine of ‘naturalism’: questions concerning the extent to which the human mind can be brought under the aegis of natural science. In their contemporary form, these questions had their origin in the ‘new science’ of the 17th century. Early materialists like Hobbes (1651) and La Mettrie (1748) rejected both explanatory and metaphysical autonomy: mind is matter in motion, and the mind can be studied by the mathematical methods of the new science just as any matter can. But while materialism (and therefore the denial of metaphysical autonomy) had to wait until the 19th century before starting to become widely accepted, the denial of explanatory autonomy remained a strong force in empiricist philosophy. Hume described his Treatise of Human Nature (1739-40) as an ‘attempt to introduce the experimental method of reasoning into moral subjects’—where ‘moral’ signifies ‘human’. And subsequent criticism of Hume’s views, notably by Kant and Reid, ensured that the question of naturalism—whether there can be a ‘science of man’—was one of the central questions of 19th century philosophy, and a question which hovered over the emergence of psychology as an independent discipline (see Reed 1994). In the 20th century, much of the philosophical discussion of the autonomy of psychology has been inspired by the Logical Positivists’ discussions of the UNITY OF.... (shrink)

According to Kant, pure intuition is an indispensable ingredient of mathematical proofs. Kant‘s thesis has been considered as obsolete since the advent of modern relational logic at the end of 19th century. Against this logicist orthodoxy Cassirer’s “critical idealism” insisted that formal logic alone could not make sense of the conceptual co-evolution of mathematical and scientific concepts. For Cassirer, idealizations, or, more precisely, idealizing completions, played a fundamental role in the formation of the mathematical and empirical (...) concepts. The aim of this paper is to outline the basics of Cassirer’s idealizational account, and to point at some interesting similarities it has with Kant’s and Peirce’s philosophies of mathematics based on the key notions of pure intuition and theorematic reasoning, respectively.

Master's Dissertation: This dissertation aims to analyse two periods of Bertrand Russell's philosophy (Platonism 1899 - 1912 and Constructivism 1913 - 1918), in which he developed his temporal theories that are studied and have an impact until today. Russell might be considered the main defender and exponent of the static theory of time. Although he revised his conception of time during the years of study, he was always in favour of the static theory. Take into account that Russell and Moore (...) revolted against English idealism in the late 19th century, and Russell became a Platonist. At the beginning of the Platonist period, Russell ignores epistemological notions, adopting a vast ontology. The first theory of time that we see in the dissertation is the absolute theory of time, defended between 1899 and 1912. The main characteristic of an absolute theory of time is that it infers instants or moments in reality. However, in the article On Denoting (1905), we see an abandonment over the years of entities that were previously part of Russell's Platonic heaven. Regarding his temporal theory, even in 1912, Russell was against the idea of a theory of relational time, as opposed to the theory of absolute time. Because a relational theory without instants as primitive entities does not guarantee the construction of a time series. Only with the development of the method of construction of instants proposed by Whitehead, Russell's workmate in the philosophical project of Principia Mathematica, a relational theory might be developed, without having to postulate moments prior to the events. From constructivism, and with the Occam's Razor principle to deflate his ontology, Russell does not postulate anything beyond what is given to us, i.e., the sense-data. In this way, all entities that might be constructed from something simpler (what we perceive via acquaintance (sense-data)) will not need to be postulated. In this dissertation, we will see the change that occurs in Russellian philosophy, taking as its starting point its purely logical arguments in favour of the absolute theory, towards a concern with its ontology over the years, in order not to postulate anything beyond what is given to us.

Renaissance philosopher, mathematician, and theologian Nicholas of Cusa (1401-1464) said that there is no proportion between the finite mind and the infinite. He is fond of saying reason cannot fully comprehend the infinite. That our best hope for attaining a vision and understanding of infinite things is by mathematics and by the use of contemplating symbols, which help us grasp "the absolute infinite". By the late 19th century, there is a decisive intervention in mathematics and its philosophy: the (...) philosophical mathematician Georg Cantor (1845-1918) says that between the realm of the finite and the absolute infinite, there is an intermediate realm partaking in properties in a certain sense of both the finite and the infinite: the transfinite realm. Like the finite, the transfinite realm is a realm of mathematical objects, numbers, and knowledge. Like the absolute infinite, the transfinite is a form of infinity insofar as transfinite sets and numbers transcend any finite number. Echoing Cusanus and neo-Platonism, Cantor says that the transfinite sequence of all ordinals is a symbol of the absolutely infinite, that is, God. Moreover, Cantor envisioned his transfinite set theory (Mengenlehre) as providing the analytical methods and techniques necessary for a comprehensive, organic, non-reductive description of nature, a Naturphilosophie. Thus Cantor’s novel mathematics is presented as part of a long tradition, to which Cusanus, Bruno, Spinoza, Leibniz and others belong, in which the infinity and infinite character of organic life forms is appreciated, and is in some sense a mirror or symbol of the divine. The doctrine of symbolism and their different approach to the laws of logic present in both the work of Cusanus and Cantor enables these thinkers to articulate a transcendental apophatic approach to divinity.

Abstract. Noticing that all of the 19th, 20th and 21st centuries treatments of trigonometry surveyed in this article are conceptually or logically defective, it is required to seek a conceptually sound and logically correct foundations of the subject. To this end, several questions have to be discussed: Is mathematics arbitrary? What does it have to do with nature? Reality? Applications? What is measure? Direct measure? Indirect measure? What are ratios? Eudoxean ratios? What is their relationship to measure? What are (...) the real numbers? What is their relationship to ratios? To measure? What are the geometric trigonometric functions? The analytic trigonometric functions? What is the relationship between them? What is the measure of an angle? what is its relationship to trigonometry?......? After dealing with these philosophical and technical questions, a treatment of both geometric and analytic trigonometry which would be conceptually sound and logically correct foundations of the subject is proposed. This treatment distinguishes between geometric trigonometric functions (the elements of whose domain are angles) and analytic trigonometric functions (the elements of whose domain are real numbers), the bridge from the former to the latter is the measure of angles. The geometric trigonometric functions are defined to be the Eudoxean ratios between appropriate straight line-segments, and the measure of an angle is defined to be its Eudoxean ratio to the radian, which is to be defined beforehand . Also, the Eudoxean ratios were defined beforehand, and it was advocated that it is conceptually sound to consider them as the positive elements of the field of the real numbers. (shrink)

After independently creating the Dynamic Mathematical Principles of LC Oscillation, I revisited scientific history. Maxwell’s era was not far from the foundational stages of modern science; he must have recognized the necessity of creating a new algebra to accurately express his equations. Consequently, I utilized AI to trace the history of science. Purpose & Background This paper addresses the long-standing "loss of soul" in mathematical physics—the transition from dynamic, phase-aware algebra to static, geometric projections. The primary goal is to restore (...) the historical legitimacy of Dynamic Algebra, a lineage rooted in Hamilton’s quaternions and Maxwell’s original formulations, which was sidelined by 19th-century pragmatic engineering. The Theoretical Framework The "Harmonious Oscillation Mathematical System" is established as a logical language that treats physical reality not as a collection of "static point-sets" but as an eternal "dynamic wave". By redefining the logical unit as a State Transition (S_n), the system utilizes universal operators: Magnetic Element (L) for causal inertia, Electric Element (C) for potential capacity, and Resistance (R) for logical entropy and physical cost. Core Innovations & Methodology Historical Rectification: We audit the transition from Maxwell’s 20 original quaternion equations to Heaviside’s vector simplifications, revealing the loss of "rotational logic" and the externalization of time. Dual-Engine Execution: The system employs a Micro-Recursive Engine for round-by-round energy settlement and a Macro-Topological Blueprint (Dynamic Wave Algebra) for dimensionality reduction. The Survival Function (F): A quantitative audit tool that predicts system persistence or collapse based on the game between driving sovereignty (E), real-part efficiency, and imaginary-part losses. Significance & Comparative Advantage Unlike the Geometric School (which lacks causal inertia) or the Traditional Algebraic School (which is overly idealized), this system forces mathematical symbols to carry real "physical weight". It demonstrates that Endogenous Time is an emergent property of oscillation cycles, meaning time effectively stands still without energy transformation. Conclusion In the era of AGI, Dynamic Algebra finds its ultimate computational realization. By leveraging Impedance Matching and Logical Filtering, this framework collapses the complexity of tens of thousands of variables into linear growth, offering a unified, high-efficiency language for economic, social, and biological evolution.

This paper aims to show that Frege’s and Hilbert’s mutual disagreement results from different notions of Anschauung and their relation to axioms. In the first section of the paper, evidence is provided to support that Frege and Hilbert were influenced by the same developments of 19th-century geometry, in particular the work of Gauss, Plücker, and von Staudt. The second section of the paper shows that Frege and Hilbert take different approaches to deal with the problems that the developments (...) in 19th-century geometry posed for the traditional Kantian philosophy of mathematics. Frege maintains that Anschauung is a source of knowledge by which we acknowledge geometrical axioms as true. For Hilbert, in contrast, axioms provide one of several correct “pictures” of reality. Hilbert’s position is thereby deeply influenced by epistemological ideas from Hertz and Helmholtz, and, in turn, influenced the neo-Kantian Cassirer. (shrink)

This paper examines the relationships between Romantic painting, poetry, and philosophy, historically tracing the circulation of images used to communicate sublimity (for example, images of ruins, storms, volcanoes, and so on). Kant's "Critique of Judgment" deployed the same vocabulary of images that appear in Coleridge and Shelly, in Church and in Turner. The discussion thereby places Kant's 3rd Critique within its cultural context. But it also reveals the massive shift from Enlightenment rationalism to 19th century historicism that Romanticism (...) enacted, and Kant's resistance to, and unwilling participation, in that shift. For the nostalgic logic of ruins, and the irruption of geological time, both of which were conceived and negotiated through sublimity, cannot be assimilated within Kant's philosophy. The treatment of the sublime in the "Critique of Judgment" represents Kant's philosophy straining at its own limits in the attempt to develop a philosophy of history and to articulate an historicized philosophical anthropology. Therefore, read through art history, Kant's 3rd. Critique represents a vital transition between Enlightenment rationalism/beauty and Romantic historicism/sublimity, along with the work of Beethoven, Goya, and the Marquis de Sade. (shrink)

The word 'reason' as used today is used ambiguous in its meaning. It may denote either of two mental faculties: a lower reason associated with discursive, linear thinking, and a higher reason associated with direct apprehension of first principles of mathematics and logic, and possibly also of moral and religious truths. These two faculties may be provisionally named Reason (higher reason) and rationality (lower reason). Common language and personal experience supply evidence of these being distinct faculties. So does classical (...) philosophical literature, the locus classicus being Plato's Divided Line analogy. -/- The effect of currently using a single word to denote both faculties not only produces confusion, but has had the effect of decreasing personal and cultural awareness of the higher faculty, Reason. Loss of a sense of Reason has arguably contributed to various psychological, social, moral, and spiritual problems of the modern age. This issue was also a central concern of 19th century Transcendentalists, who reacted to the radical empiricism of Locke. It would be advantageous to adopt consistent terms that make explicit a distinction between higher and lower reason. One possibility is to re-introduce the Greek philosophical terms nous and dianoia for the higher and lower reason, respectively. This discussion has certain parallels with the recent theories of McGilchrist (2009) concerning the increasingly left-brain hemisphere orientation of human culture. (shrink)

Soren Kierkegaard was a profound and prolific writer in the Danish “golden age” of intellectual and artistic activity. His work crosses the boundaries of philosophy, theology, psychology, literary criticism, devotional literature and fiction. Kierkegaard brought this potent mixture of discourses to bear as social critique and for the purpose of renewing Christian faith within Christendom. At the same time he made many original conceptual contributions to each of the disciplines he employed. He is known as the “father of existentialism”, but (...) at least as important are his critiques of his peer Hegel and of the German romantics, his contributions to the development of modernism, his literary experimentation, his vivid re-presentation of biblical figures to bring out their modern relevance, his invention of key concepts which have been explored and redeployed by thinkers ever since, his interventions in contemporary Danish church politics, and his fervent attempts to analyse and revitalise Christian faith. Kierkegaard is regarded by modern contemporaries as somewhat of an intellectual ‘time bomb’, although writing in the early 19th century, Kierkegaards ideas did not explode upon the western intellectual world until the 20th century. Both the contemporary philosophical and theological scenes have been profoundly influenced by this explosion, and chances are that in coming generations writers will still draw insight on some of Kierkegaards unique ideas. His philosophy on religious belief took centuries of philosophical discourse concerning the existence of God and took the discussion in a completely new direction. Up until the writing of Kierkegaard religious philosophy was centered around attempts to ‘prove’ Gods existence via means of a logically consistent, well reasoned argument ala Aquinas’ Five Ways, Anselm etc. To vindicate religious belief, one would traditionally offer some form of structured argument in favour of deity that appealed to reason e.g First Cause, Ontological argument etc, a field which is now known as apologetics-the intellectual defense of religious belief. For Kierkegaard however, reason and faith are a false dichotomy- rational argument and human reason are somewhat irrelevant to religious belief,and this plays a central role in his philosophical doctrine which is an attempt to vindicate Christian faith through his thesis that ‘truth is subjectivity’(Schaeffer, 1982). Firstly, what will be discussed here is a critical evaluation of Kierkegaards philosophy of religious belief as expounded in his works Philosophical Fragments and Concluding Unscientific Postscript. Secondly, a look at some responses and criticisms of Kierkegaards religious views- as he was a notoriously ambiguous and vague writer, he wrote the majority of his famous works pseudonymously, his work has been frequently scrutinised. Finally, concluding with an analysis of his philosophy and if we can consider his work a complete vindication of religious belief. (shrink)

The study examines the modes of representation and communication of information through illustrative teaching aids in the 19th century. It focuses primarily on the didactic wall paintings and the tradition of lectures with slides and notes, how could the experience of these types of collectively observed images influence impressions and expectations of early film audiences. Didactic images are here analyzed primarily in terms of their compositional features, but in an effort to explain how processuality penetrated into the didactic (...) image of the 19th century also with regard to the aspect of time. As a result, the study calls for a reassessment of the importance of the didactic wall painting in the formation of modern visuality and observational practices of the late 19th century. (shrink)

This paper provides an analysis of Franz Brentano’s thesis that psychology employs a distinctive method, which sets it apart from physiology. The aim of the paper is two-fold: First, I situate Brentano’s thesis (and the broader metaphysical system that underwrites it) within the context of specific debates about the nature and status of psychology, arguing that we regard him as engaging in a form of boundary work. Second, I explore the relevance of Brentano’s considerations to more recent debates about autonomy (...) on the one hand and theoretical and/or methodological integration on the other. I argue that Brentano puts his finger on the idea that an integrated research process presupposes the existence of distinct methods and approaches, and that he highlights the philosophical challenge of accounting for such distinct methods. I suggest that Brentano’s ideas offer unconventional perspectives on current debates, in particular regarding first-person methods and the investigative process in cognitive science. (shrink)

Friedrich Nietzsche’s criticism towards the substance-concept „I“ plays an important role in his late thought, and can be properly understood by making reference to the 19th century debate on the scientific psychology. Friedrich Lange and Ernst Mach gave an important contribution to that debate. Both of them developed the ideas of Gustav Fechner, and thought about a „psychology without soul“, i.e. an investigation that gives up with the old metaphysics of substance in dealing with the mind-body problem. In (...) this paper I shall deal with both Lange and Mach (whose writings has been read by Nietzsche), in order to shed some light on Nietzsche’s rejection of the „I“ in philosophy. (shrink)

In this paper we look at the manual analysis of arguments and how this compares to the current state of automatic argument analysis. These considerations are used to develop a new approach combining a machine learning algorithm to extract propositions from text, with a topic model to determine argument structure. The results of this method are compared to a manual analysis.

Scholars often argue that Charles Sanders Peirce was responsible for Josiah Royce's semiotic turn in _The Problem of Christianity_ of 1913. Thus scholars tend to assume that a _Roycean_ approach to semiotics was a later development and derives almost entirely from Peirce's semiotics. Far from a later development, Royce probably read Peirce much earlier. Indeed, even before Royce had read Peirce, the kernel of a Rocyean approach to semiotics is found in the dissertation of 1878. Thus the present essay will (...) prove that a Roycean approach to semiotics did not have a basis in Peirce's semiotics, whether early or later, but rather grew out of Royce's earliest writings. The first part will reconstruct the early pragmatism in the dissertation of 1878 and find that the kernal of a Roycean approach to semiotics was the idea of a _mediating third_. The second part will show how the disseration's pragmatism develops into a phenomenology of time that contains Royce's earliest semiosic insights. The third part will explain how the early pragmatism and phenomenology come together in the argument on the possibility of error from Royce's _The Religious Aspect of Philosophy_ of 1885. The possibility of error is Royce's original argument for absolute idealism, so the essay will conclude that a Roycean approach to semiotics entails a semiotics of the absolute. (shrink)

At the end of the 19th century, most professional historians – wherever they existed – deemed history to be a form of knowledge ruled by a method that bears no resemblance with those most commonly traceable in the natural sciences. The bulk of the historian’s task was then frequently regarded as being the application of procedures frequently referred to as ‘historical method’. In the context of such an emerging interest on historical methods and methodology, at least three textbooks (...) stand out: Johann Gustav Droysen’s Grundriss der Historik (Outline of the Theory of History), Ernst Bernheim’s Lehrbuch der historischen Methode (Handbook of Historical Method), and Charles Langlois and Charles Seignobos’s Introduction aux études historiques (Introduction to the Study of History). These books were quite influential in Germany, France, and elsewhere, and they very much helped promote a general idea of historical method that would become relatively consensual among historians of many nationalities by the early 20th century. Such a relative agreement on historical method sponsored both the communication and the development of a sense of disciplinary identity among historians trained within different and sometimes conflicting national traditions. It was then partially extended, partially challenged, and surely made more complex when, from the 1920s on, social and economic historians became a good part of the historiographical establishment in many countries. The three books by Droysen, Bernheim, and Langlois and Seignobos were already pieced together by Rolf Torstendahl, who studied them as a group of texts that, despite their differences, contributed to shape the developments outlined above. However, Torstendahl’s primary aim was to show how Droysen, Bernheim, and Seignobos all resorted to ‘method’ as a way to circumvent skepticism against the possibility of historical knowledge, rather than investigate the internal interrelationships between the three texts. In this chapter I follow precisely this latter, not yet taken, road, focusing on crucial cross-references between the Grundriss, the Lehrbuch, and the Introduction. I intend to show that, at a general level, the schemes of historical method found in these texts are largely convergent, and that this convergence is due to Bernheim’s reading of Droysen and to Langlois and Seignobos’s reading of Bernheim. I will attempt to do it through a regressive approach that starts with an analysis of the Introduction. Aspects of the editorial history and circulation of the three texts will also be briefly addressed, as a way to illustrate their special importance within the framework of early 20th century historical theory. Because my argument calls for a focus on the most general lines of Droysen’s, Bernheim’s, and Langlois and Seignobos’s schemes of historical method, I will, for the sake of consistency, refrain from analysing in-depth the complex epistemological and ontological arguments in which those schemes are nested.

This chapter explores some of the major developments in the philosophical understanding of suicide in 19th Century Western thought. Two developments in particular are considered. The first is a widespread shift towards thinking about suicide in medical terms rather than moral terms. Deploying methods initiated by a number of French and German thinkers in the preceding century who worked at the then emerging interface between the social and biological sciences, a number of 19th century thinkers (...) ejected what they took to be old metaphysical superstitions about ‘good’ and ‘evil’, and replaced them with (allegedly) hard-nosed scientific diagnoses of ‘health’ and ‘sickness’. Dismissing traditional moral arguments against the permissibility of suicide, the phenomenon came to be viewed as a symptom of decline or degeneration. How variations of this view, in biological and social contexts, reorientated practical responses to suicide in terms of treatment rather than moral condemnation is explored. The second 19th century development in philosophical thought with respect to suicide the chapter considers concerns its place in one of the most significant controversies in Germany from 1860 to the turn of the century: the Pessimismusstreit or ‘pessimism dispute’. While philosophical pessimism might be thought to vindicate or even entail suicide, many of the most prominent pessimists—including Arthur Schopenhauer and Eduard von Hartmann—denied that this was the case, and perhaps surprisingly took suicide to involve a special kind of moral and/or epistemic failing. The chapter aims to elucidate the different arguments which pessimists appealed to in order to ground this position. (shrink)

The Polish philosophy of mathematics in the 19th century had its origins in the Romantic period under the influence of the then-predominant idealist philosophies. The decline of Romantic philosophy precipitated changes in general philosophy, but what is less well known is how it triggered changes in the philosophy of mathematics. In this paper, we discuss how the Polish philosophy of mathematics evolved from the metaphysical approach that had been formed during the Romantic era to the more modern positivistic (...) paradigm. These evolutionary changes are attributed to the philosophers Henryk Struve, Antoni Molicki and Julian Ochorowicz, and mathematicians Karol Hertz and Samuel Dickstein. We also show how implicit ideas (i.e., those not declared openly) from the area between the philosophy of science and general philosophy played a crucial role in the paradigm shift in the Polish philosophy of mathematics.

The article examines the collaborations between the pensionnaires of the Villa Medici in Rome and the members of the French School of Athens, shedding light on the complex relationships between architecture, art, and archeology. The second half of the 19th century was a period during which the exchanges and collaborations between archaeologists, artists, and architects acquired a reinvented role and a dominant place. Within such a context, Athens was the place par excellence, where the encounter between these three (...) disciplines took place. The main objective of the article is to render explicit how the revelations of archeology, actively disseminated by the members of the French School of Athens—the “Athéniens”—had an important impact on the approach of certain pensionnaires of the Villa Medici in Rome. Particular emphasis is placed on certain pensionnaires, who decided to devote their envois to ancient monuments of Greece. In parallel, the article intends to shed light on the methods that helped the pensionnaires-architects of the Villa Medici in Rome appropriate archaeological discoveries concerning Greek antiquities. The article takes, as a starting point, the following hypothesis: to better understand the figure of the architect-archaeologist, of whom Jacques Ignace Hittorff is an emblematic example, it is pivotal to bear in mind that before the second half of the 19th century neither the figure of Hellenic archeology nor the figure of the architect had yet acquired their autonomy. Taking into account that Johann Joachim Winckelmann, in the middle of the 18th century, forged an ideal Greek model, which was criticized during the second half of the 19th century, the article also sheds light on the fact that the revelations of archaeologists have called into question the Winckelmannian image of Greece. Another aspect that is explored in the article is Jacques Ignace Hittorff’s studies concerning the polychromy of ancient Greek monuments, paying special attention to his Restitution du temple d’Empédocle à Sélinonte ou l’Architecture polychrome chez les Grecs. The article also explores how the shifts of the status of philhellenism are related to the mutations of the meaning of travel to Greece. In parallel, it investigates the impact of Greek independence on the ideals of beauty and nature in arts, as well as how Greek independence is related to the intensification of the interest in the excavations of Greek antiquities.
