In this paper I first aim to identify, from a perspective mindful of both analytic and Continental traditions, the central normative issues at stake in the various debates concerning commodification in law. Although there now exists a wealth of thoughtful literature in this area, I often find myself disoriented within the webs of moral criteria used to analyze the increasingly ubiquitous practice of converting legal goods into monetary values. I therefore attempt to distinguish and organize these often conflated conceptual distinctions (...) across several registers of moral analysis. Second, I formulate what I consider the most illuminating questions regarding the criteria used to evaluate commodification in law. Critiques of commodification in law face what I call problems of ideology, intractability, and hyperbole, and identifying these issues helps to explain the momentum of the law and economics movement.

The reality of revelation was one of the fundamental questions that\noccupied George Tyrrell as a writer until he died on 15 July 1909. The\ncentenary of his death is an opportune time to engage this English\nModernist in a dialogue with Karl Rahner on the subject of revelation.\nTyrrell insists on the primacy of the interior experience of revelation.\nAn exaggerated emphasis on inner religious experience, however, led him\ninevitably to a separation of the interior dimension of revelation from\nits verbal expressions and doctrinal formulations.\nRahner (...) also affirms the primacy of the originating inner experience of\nGod but stresses at the same time the intrinsic unity between this\ntranscendental revelation and its categorical, historical dimension.\nRevelation corresponds to the symbolic nature of the addressee. The\nMystery of the Incarnation is the point of reference for understanding\nGod's self-communication. The fullness of revelation has been realized\nin the indissoluble and irreversible unity of the Divine Logos with the\nMan Jesus. (shrink)
Zwischen 1987 und 1994 sandte ich 20 Briefe an Karl Popper. Die meisten betrafen Fragen bezüglich seiner Antiinduktionsbeweise und seiner Wahrscheinlichkeitstheorie, einige die organisatorische und inhaltliche Vorbereitung eines Fachgesprächs mit ihm in Kenly am 22. März 1989 (worauf hier nicht eingegangen werden soll), einige schließlich ganz oder in Teilen nicht-fachliche Angelegenheiten (die im vorliegenden Bericht ebenfalls unberücksichtigt bleiben). Von Karl Popper erhielt ich in diesem Zeitraum 10 Briefe. Der bedeutendste ist sein siebter, bestehend aus drei Teilen, geschrieben am (...) 21., 22. und 23. Oktober 1992, in dem er eine Vorform jener Definition der probabilistischen Unabhängigkeit entwickelte, die er 1994 im neuen Anhang *XX der 10. Auflage seiner Logik der Forschung (LdF) der wissenschaftstheoretischen Forschergemeinde vorstellte. Der berührendste ist sein letzter, geschrieben am 26. Juli 1994, in dem er trotz Erschöpfung mit Humor schildert, wie mühselig der Druck des Anhangs *XX verlaufen ist. Mein Bericht ist zugleich chronologisch und systematisch gegliedert: die ersten, vergleichsweise wenigen Briefe, großteils 1987 geschrieben, handeln von der Induktion; der große Rest, zeitlicher Schwerpunkt 1992, beschäftigt sich mit der Wahrscheinlichkeitstheorie. Das Kapitel 1 über Induktion ist in vier Abschnitte unterteilt: 1.1 Das Popper/Miller-Argument: eine Nachkonstruktion 1.2 Karl Poppers Brief vom 25.8.1987: Deduktive Stützung 1.3 Karl Poppers Brief vom 29.9.1987: Nochmals zur deduktiven Stützung 1.4 Echt induktive Stützung und Schwächung: zwei eigene Beweise Das Kapitel 2 über Wahrscheinlichkeit ist ebenfalls in vier Abschnitte unterteilt: 2.1 Ein Mangel an Überschußgesetzen in der Logic of Scientific Discovery 2.2 Probabilistische Unabhängigkeit 2.3 Wahrscheinlichkeitstheorie und Wahrscheinlichkeitssemantik 2.4 Die neue Unabhängigkeitsdefinition im Anhang *XX der LdF.

This paper looks at how the idea of pointless topology itself evolved during its pre-localic phase by analyzing the definitions of the concept of topological space of Menger and Nöbeling. Menger put forward a topology of lumps in order to generalize the definition of the real line. As to Nöbeling, he developed an abstract theory of posets so that a topological space becomes a particular case of topological poset. The analysis emphasizes two points. First, Menger's geometrical perspective was superseded by (...) an algebraic one, a lattice-theoretical one to be precise. Second, Menger's bottom–up approach was replaced by a top–down one. (shrink)
Popper first developed his theory of scientific method – falsificationism – in his The Logic of Scientific Discovery, then generalized it to form critical rationalism, which he subsequently applied to social and political problems in The Open Society and Its Enemies. All this can be regarded as constituting a major development of the 18th century Enlightenment programme of learning from scientific progress how to achieve social progress towards a better world. Falsificationism is, however, defective. It misrepresents the real, problematic aims (...) of science. We need a new conception of scientific method, a meta-methodology which provides a framework for the improvement of the aims and methods of science as scientific knowledge improves. This aim-oriented empiricist idea can be generalized to form a conception of rationality – aim-oriented rationality – which helps us improve problematic aims and methods whatever we may be doing. In this way, Popper’s version of the Enlightenment programme can be much improved, indeed transformed. (shrink)
There are two motivations commonly ascribed to historical actors for taking up statistics: to reduce complicated data to a mean value (e.g., Quetelet), and to take account of diversity (e.g., Galton). Different motivations will, it is assumed, lead to different methodological decisions in the practice of the statistical sciences. Karl Pearson and W. F. R. Weldon are generally seen as following directly in Galton’s footsteps. I argue for two related theses in light of this standard interpretation, based on a (...) reading of several sources in which Weldon, independently of Pearson, reflects on his own motivations. First, while Pearson does approach statistics from this "Galtonian" perspective, he is, consistent with his positivist philosophy of science, utilizing statistics to simplify the highly variable data of biology. Weldon, on the other hand, is brought to statistics by a rich empiricism and a desire to preserve the diversity of biological data. Secondly, we have here a counterexample to the claim that divergence in motivation will lead to a corresponding separation in methodology. Pearson and Weldon, despite embracing biometry for different reasons, settled on precisely the same set of statistical tools for the investigation of evolution. (shrink)
An exposition of Karl Marx’s argument in the Grundrisse for the logical development of money, this essay is divided into three parts. Since Marx is concerned to distinguish himself and his method from that of the seventeenth century political economists, I begin my paper with a brief reflection on “the scientifically correct method” or the “theoretical method” (Grundrisse 101 and 102). The second part of this paper considers how Marx justifies beginning his reflection with the concept of production in (...) general. To understand the importance that Marx attributes to production, one must also appreciate the way in which distribution, exchange, and consumption belong to the sphere of production. In the remaining pages of this section of my paper, then, I attempt to reconstruct Marx’s argument for the way in which these concepts (distribution, exchange, and consumption) are to be understood in relation to the sphere of production.

Karl Christian Friedrich Krause war ein bemerkenswerter Denker des Deutschen Idealismus. Seine Schriften können ohne Zweifel mit denen Hegels, Schellings und Fichtes konkurrieren. Gerade im Bereich der theoretischen Philosophie bietet das Krausesche Œuvre eine Fundgrube an Einsichten und Argumenten, die der heutigen, oftmals betont postmodernen oder atheistischen Philosophie eine dringend benötigte Kontrastfolie sein können. Sinn und Zweck der Arbeit ist es, den Panentheismus Krauses zeitgemäß darzustellen und Brückenschläge zur heutigen religionsphilosophischen Debatte aufzuzeigen.
In the book under review, Walter Reese-Schafer provides a concise Introduction to the sources, themes and conclusions of the philosophy of Karl-Otto Apel, Emeritus Professor at Frankfurt and close colleague of Jurgen Habermas. There are both Kantian and Peircean themes in Apel, with the chief focus on the concept of discourse ethics.
When Western Marxist sociologists, such as Jean Buadrillard, constructed their critical theory of consumer society, they took the consumer society as an objective fact and methodologically restricted themselves to the non-historical method of sociology, making them unable to grasp the correct meaning of Karl Marx's historical materialist methodology. Thus, they were unable to adequately critique and transcend consumer society. After spending the early 1850s building a theoretical foundation, Marx pointed out in 1857–1858 Economical Manuscript and 1861–1863 Economical Manuscript that (...) the governing model of capital was so complicated that it made consumption very important to the socio-economic form. Moreover, he explained the way of surpassing the conscious form of fetishism developed in consumer society from the perspective of the development of capitalist production. (shrink)
In 1967, American biologist Adrian Wenner (1928-) launched an extensive challenge to Karl von Frisch's (1886-1982) theory that bees communicate to each other the direction and distance of food sources by a symbolic dance language. Wenner and various collaborators argued that bees locate foods solely by odors. Although the dispute had largely run its course by 1973 -- von Frisch was awarded a Nobel Prize, while Wenner withdrew from active bee research -- it offers us a rare window into (...) mid-twentieth century discussions about animals, language, and cognition. Historians, sociologists, and scientists have commented on the debate and its outcome, but none has seriously questioned why von Frisch and Wenner pursued such different explanations of the bees' dances. In this paper, I explore von Frisch and Wenner's differing visions of animals and their behaviors and show how these contributed to their respective positions. Von Frisch's early-twentieth-century training in experimental physiology disposed him to focus on individual animals, their abilities, and their behaviors' evolutionary significance. Wenner, by contrast, was trained in mathematics and statistics and the Schneirla school of behavior. He viewed the bees' behaviors probabilistically with an eye toward the entire hive and its surroundings and ultimately explained them in terms of simple stimulus--response conditioning. Finally, while the debate was resolved in von Frisch's favor, he neither waged nor won the battle by himself. Instead, I show that practitioners, whose agendas ranged from the nascent fields of sociobiology to cognitive ethology, took up the cause of the communicating bees. (shrink)
The paper focuses on one central aspect of Karl Mannheim’s sociology of knowledge: his exemption of the contents of mathematics and the natural sciences from sociological investigations. After emphasizing the importance of Mannheim’s contribution and his exemption-thesis to the history and development of the field and the problem of relativism, I survey several interpretations of the thesis – especially those put forward by proponents of the so-called ‘Strong Programme’. I argue that these interpretations do not get the philosophical background (...) and impetus of Mannheim’s contribution right. By distinguishing between naturalistic and anti-naturalistic strands in Mannheim’s work I propose a new reading on which Mannheim did not exempt the contents of the areas in question principally or because of a lack of nerve and will. It is argued that Mannheim’s exemption-thesis rather is a consequence of his own sketchy sociological investigations of ‘the paradigm of the natural sciences’. (shrink)
Panentheism is an often-discussed alternative to Classical theism, and almost any discussion of panentheism starts by way of acknowledging Karl Christian Friedrich Krause (1781–1832) as the person who coined the term.1 However, apart from this tribute, Krause's own panentheism is almost completely unknown. In what follows, I first present a brief overview of Krause's life and correct some misconceptions of his work before I turn to the core ideas of Krause's own panentheistic system of philosophy. In brief, Krause elaborates (...) a scientific holism that is anchored in intellectual intuition of the Absolute as the one principle of being and recognition. The task of philosophical speculation consequently is twofold: the analytic-ascending part of philosophy proceeds by way of transcendental reflection and according to Krause enables us to obtain intellectual intuition. The synthetic-descending part of philosophy starts by way of showing that science as a whole is an explication of the original union of the Absolute as apprehended in intellectual intuition. Once this is achieved, Krause argues that the emerging philosophy of science is most adequately referred to as “panentheism” since everything is what it is “in and through” the Absolute, while the Absolute itself is not reducible to anything in particular. I end by showing how to relate Krause's panentheism to recent philosophical discussion. (shrink)
The present contribution aims at defining the relation between cybernetics and social theory from the perspective of society as order. After an historical framework of the cybernetic movement, a careful reading of the works of Norbert Wiener, in which he introduced the concept of feed-back and the idea of information society, has revealed a keen awareness about the social effects of technological innovation. Among the social scientists who had made use of cybernetic concepts, it has been considered the work of (...)Karl Deutsch, which was one of the first completely cybernetic perspective for the study of political and social phenomena. The main conclusion is that cybernetics, as a meeting point between different disciplines, has produced an image of self-regulated society in line with the image of society as order. (shrink)
Der Begriff der Vernunft gehört zu den Begriffen, die für Jaspers‘ philosophisches Denken und schriftliche verfaßte Philosophie eine besonders wichtige Rolle spielen. Gleichwohl kann es im Folgenden nicht um Jaspers‘ ganze Philosophie gehen, sondern nur um seinen Begriff der Vernunft. Sein Begriff der Vernunft ist jedoch für die wesentlichen Grundzüge seiner Philosophie konstitutiv und charakteristisch. Im ersten Teil werde ich kurz auf die Entwicklung der Schriften eingehen, in denen Jaspers hauptsächlich sein Verständnis von Vernunft dargelegt hat. Im zweiten Teil werde (...) ich dann Jaspers‘ Begriff der Vernunft anhand einiger wichtiger Aussagen in den genannten Werken rekonstruieren. Dabei kann jedoch nur der wesentliche Gehalt seines Begriffes der Vernunft berücksichtigt werden und nicht alle Strukturen, Formen und Funktionen der Vernunft, die dann für seine Philosophie charakteristisch und konstitutiv sind. Im dritten Teil werde ich dann kurz den systematischen Ort und Stellenwert von Jaspers‘ Begriff der Vernunft in seiner Vernunftphilosophie beleuchten. (shrink)
The two principal models of design in methodological circles in architecture—analysis/synthesis and conjecture/analysis—have their roots in philosophy of science, in different conceptions of scientific method. This paper explores the philosophical origins of these models and the reasons for rejecting analysis/synthesis in favour of conjecture/analysis, the latter being derived from Karl Popper’s view of scientific method. I discuss a fundamental problem with Popper’s view, however, and indicate a framework for conjecture/analysis to avoid this problem.
This essay has three interrelated goals: first, to sketch the basic contours of Georg Helm's energetic theory; second, to describe his attempt in his Grundzüge der mathematischen Chemie. Energetik der chemischen Erscheinungen (1894) to apply that theory to the (then) burgeoning new field of physical chemistry. This is of some interest historically, since Helm's work is the most sophisticated attempt to develop the whole of physical chemistry mathematically from an energetic point of view. Nevertheless, it is seriously flawed technically. (...) Moreover, that development is inconsistent with Helm's considered way of thinking about energy and energetic change. So a third goal of the essay is to explain his mature conception of the goal of energetics. I begin with a brief introduction to Helm and energetics, and end with some general conclusions about the success of Helm's mathematische Chemie. (shrink)
Karl Jaspers zählt zu den bedeutendsten Philosophen des 20. Jahrhunderts. Obwohl es bereits eine international etablierte Jaspersforschung gibt, haben die meisten seiner Werke jedoch noch keinen angemessenen Eingang in die historische und systematische Lehre der Philosophie gefunden. Diese Aufsatzsammlung gibt erstmals einen Einblick in die wichtigsten Begriffe seines philosophischen Denkens. Zu diesen Begriffen gehören Begriffe wie Grenzsituation, Freiheit, Menschenbild, Kommunikation, Philosophischer Glaube, Chiffre, Böses, Wahrheit, Vernunft, Gehäuse, Wissenschaft, Logik, Sprachphilosophie, Psychopathologie, Psychologie der Weltanschauung, Ethik, Einsamkeit, Erziehung, Politik, Universität, Achsenzeit, (...) Philosophia perennis und interkulturelle Philosophie. Einige dieser Begriffe wurden von Jaspers geprägt und gingen dauerhaft als neue Begriffe in die Philosophie, die Psychologie und die Psychopathologie ein. Die anderen Begriffe knüpfen zwar dem Wortlaut nach an die klassische Tradition der europäischen Philosophie an, wurden von Jaspers jedoch im Sinne einer Weltphilosophie umgestaltet und erweitert. Dieser Sammelband ist nicht nur ein einführendes Kompendium für Studierende der Philosophie, der verschiedenen Theologien der Weltreligionen sowie der Sozial- und Kulturwissenschaften. Er kann auch philosophisch Interessierten den Zugang zur Philosophie von Jaspers erleichtern. (shrink)
In this paper, the political pamphlet “Der Hessische Landbote” by the eminent German author, Georg Büchner (1813–1837), will be positioned within the context of its political and historical background, analyzed as to its argumentative and stylistic structure, and critically evaluated. It will be argued that propaganda texts such as this should be evaluated by taking into account both rhetorical perspectives and standards of rational discussion. As far as argumentative structure is concerned, a modified version of the Toulmin scheme will (...) be used for the description of three passages of the “Landbote”. As far as stylistic techniques are concerned, Büchner’s strategic use of some figures of speech, especially parallelism, metaphor and metonymy will be examined. As to the critical evaluation, the recently developed concept of “strategic maneuvering” within Pragma-Dialectics, the typology of argumentative dialogues established by D. Walton, and sets of critical questions will be used to assess the status of the arguments within the “Landbote” as potentially fallacious ones. (shrink)
The paper tries to grasp and acquire Karl Jaspers’s philosophical-mental horizons mainly with the terminological and methodological instruments of the musical – primarily symphonic – thematisation. Namely those typically jaspersian tensions and impulses, which in their connections to the Encompassing and to Existence are apparently far from them – turning back (and forth) to the oriental and western meta- physics of Sound and Light. While the “philosophical problems” elevated into themes, now start to inter- weave into spectacle (spectaculum) and (...) – along this – they open up as ciphers. Concomitantly they do not send us – western thinkers – beyond the World, but contrarily, they attach us to the communicative re- sponsibility towards the world, to ourselves respectively to others.

Le Obiezioni contro la Teoria medica di G.E. Stahl, tradotte per la prima volta in italiano, rappresentano un documento di particolare interesse storico-filosofico. Da una parte Georg Ernst Stahl (1659-1734), medico, chimico, fisico, sostenitore di una fisiologia corporea a impronta “vitalista” e dall’altra Gottfried Wilhelm Leibniz (1646-1716), genio universale della matematica e della filosofia dell’età barocca. Il fulcro della polemica riguarda la possibilità di capire se e in che misura l’organizzazione meccanica di un corpo organico sia di per se (...) sufficiente a spiegare il fenomeno della vita “biologica”, o se invece si debba postulare la presenza di princìpi vitali capaci di integrare le leggi fisiologiche che strutturano la corporeità. A dispetto della lontananza storica, o anzi forse proprio in virtù di tale lontananza, la polemica tra Leibniz e Stahl ci aiuta a decifrare le radici di uno dei refrain più abusati di tanta filosofia contemporanea, il tema cioè della ‘naturalizzazione’ della vita e dello spirito. L’idea di espungere tutti gli elementi “soprannaturali” (l’anima, gli spiriti, etc.) dal novero delle spiegazioni scientifiche non è certo un’idea novecentesca e si confronta in questo caso non solo con la sua tesi opposta, ma soprattutto con una vasta gamma di soluzioni intermedie e di varianti non riduzioniste, di cui proprio la filosofia di Leibniz è uno splendido esempio. Il volume è accompagnato da un saggio di postfazione intitolato Vita e organismo tra filosofia e medicina: le ragioni di una polemica. (shrink)
"Capital is moved as much and as little by the degradation and final depopulation of the human race, as by the probable fall of the earth into the sun. Apres moi le deluge! is the watchword of every capitalist and of every capitalist nation" (Marx, CAPITAL Vol 1, 380-381).
In this paper, the (possible) role of model theory forstructuralism and structuralist definitions of ``reduction'' arediscussed. Whereas it is somewhat undecisive with respect tothe first point – discussing some pro's and con's ofthe model theoretic approach when compared with a syntacticand a structuralist one – it emphasizes that severalstructuralist definitions of ``reducibility'' do not providegenerally acceptable explications of ``reducibility''. This claimrests on some mathematical results proved in this paper.
This paper is an investigation into what could be a goodexplication of ``theory S is reducible to theory T''''. Ipresent an axiomatic approach to reducibility, which is developedmetamathematically and used to evaluate most of the definitionsof ``reducible'''' found in the relevant literature. Among these,relative interpretability turns out to be most convincing as ageneral reducibility concept, proof-theoreticalreducibility being its only serious competitor left. Thisrelation is analyzed in some detail, both from the point of viewof the reducibility axioms and of modal logic.
In his paper "Finitism" (1981), W.W. Tait maintains that the chief difficulty for everyone who wishes to understand Hilbert's conception of finitist mathematics is this: to specify the sense of the provability of general statements about the natural numbers without presupposing infinite totalities. Tait further argues that all finitist reasoning is essentially primitive recursive. In this paper, we attempt to show that his thesis "The finitist functions are precisely the primitive recursive functions" is disputable and that another, likewise defended by (...) him, is untenable. The second thesis is that the finitist theorems are precisely the universal closures of the equations that can be proved in PRA. /// En su articulo "Finitism" (1981), W.W. Tait sostiene que la dificultad principal para quien quiere comprender la concepción hilbertiana de la matemática finitista es ésta: especificar el sentido de la demostrabilidad de enunciados generales sobre los números naturales sin presuponer totalidades infinitas. Además, Tait argumenta que todo razonamiento finitista es esencialmente primitivo recursivo. En este artículo tratamos de mostrar que su tesis "Las funciones finitistas son precisamente las funciones primitivas recursivas" es discutible y que otra, también defendida por él, resulta insostenible. La segunda tesis es que los teoremas finitistas son precisamente las clausuras universales de las ecuaciones que pueden demostrarse en PRA. (shrink)
Hilbert developed his famous finitist point of view in several essays in the 1920s. In this paper, we discuss various extensions of it, with particular emphasis on those suggested by Hilbert and Bernays in Grundlagen der Mathematik (vol. I 1934, vol. II 1939). The paper is in three sections. The first deals with Hilbert's introduction of a restricted ? -rule in his 1931 paper ?Die Grundlegung der elementaren Zahlenlehre?. The main question we discuss here is whether the finitist (meta-)mathematician would (...) be entitled to accept this rule as a finitary rule of inference. In the second section, we assess the strength of finitist metamathematics in Hilbert and Bernays 1934. The third and final section is devoted to the second volume of Grundlagen der Mathematik. For preparatory reasons, we first discuss Gentzen's proposal of expanding the range of what can be admitted as finitary in his esssay ?Die Widerspruchsfreiheit der reinen Zahlentheorie? (1936). As to Hilbert and Bernays 1939, we end on a ?critical? note: however considerable the impact of this work may have been on subsequent developments in metamathematics, there can be no doubt that in it the ideals of Hilbert's original finitism have fallen victim to sheer proof-theoretic pragmatism.

This paper is an attempt to bring together two separated areas of research: classical mathematics and metamathematics on the one side, non-monotonic reasoning on the other. This is done by simulating nonmonotonic logic through antitonic theory extensions. In the first half, the specific extension procedure proposed here is motivated informally, partly in comparison with some well-known non-monotonic formalisms. Operators V and, more generally, U are obtained which have some plausibility when viewed as giving nonmonotonic theory extensions. In the second half, (...) these operators are treated from a mathematical and metamathematical point of view. Here an important role is played by U -closed theories and U -fixed points. The last section contains results on V-closed theories which are specific for V. (shrink)
From early work of N. Goodman to recent approaches by H. Field and D. Lewis, there have been attempts to combine 2nd order languages with calculi of individuals. This paper is a contribution, containing basic denitions and distinctions and some metatheorems, to the development of a general metatheory of such theories.
Nature and society are dichotomized in much discussion in critical theory or science, largely because of the want of a satisfactory way to connect or combine the problems and prospects involved. Yet the interconnection is nowhere more apparent than in the idea of the social or cultural, or capitalism as second nature. This article, developed from the opening lecture for the Thesis Eleven Conference `Landprints Over Boundaries: in Honour of George Seddon', compares Marx and Seddon on nature and second nature, (...) in order to suggest points of contact and traffic between Seddon's project and that of critical theory, not least with reference to problems of place and the peculiarities of the antipodes. How to connect the two? Marx shifts from the anthropological and historical to the more abstract concerns with capital as second nature; Seddon remains more inquisi-tive, empirical, though comparative and cosmopolitan in nature. Reading the two projects together is an interesting exercise in orientation for critical theory today. (shrink)
Since its first publication in 1981, Karl Marx has become one of the most respected books on Marx's philosophical thought. Allen Wood explains Marx's views from a philosophical standpoint and defends Marx against common misunderstandings and criticisms of his views. All the major philosophical topics in Marx's work are considered: alienation, historical materialism, morality, philosophical materialism, and the dialectical method. The second edition has been revised to include a new chapter on capitalist exploitation and new suggestions for further reading. (...) Wood has also added a substantial new preface which looks at the fall of the Soviet Union and ambivalence towards capitalism, and explores Marx's relevance and place in the twenty-first century.

Karl Popper has been one of the few philosophers of sciences who has influenced scientists. I evaluate Popper's influence on our understanding of evolutionary theory from his earliest publications to the present. Popper concluded that three sorts of statements in evolutionary biology are not genuine laws of nature. I take him to be right on this score. Popper's later distinction between evolutionary theory as a metaphysical research program and as a scientific theory led more than one scientist to misunderstand (...) his position on evolutionary theory as a scientific theory. In his later work Popper also introduced what he took to be improvements of evolutionary theory. Thus far these improvements have had almost no influence on evolutionary biology. I conclude by examining the influence of Popper on the reception of cladistic analysis. (shrink)
Karl Popper is the greatest philosopher of the 20th century. No other philosopher of the period has produced a body of work that is as significant. What is best in Popper's output is contained in his first four published books. These tackle fundamental problems with ferocious, exemplary integrity, clarity, simplicity and originality. They have widespread, fruitful implications, for science, for philosophy, for the social sciences, for education, for art, for politics and political philosophy. This article provides a critical survey (...) of Popper’s work. (shrink)
