Mit seinem Einfluß auf die Entwicklung der Physiologie, Physik und Geometrie ist Hermann von Helmholtz wie kaum ein anderer Wissenschaftler der zweiten Hälfte des 19. Jahrhunderts repräsentativ für die Naturforschung in Deutschland. Nicht weniger repräsentativ nimmt sich die Entwicklung seiner Wissenschaftsauffassung aus. Während er bis in die späten 60er Jahre einen emphatischen Wahrheitsanspruch der Wissenschaft vertrat, begann er in der nachfolgenden Zeit, die Geltungsbedingungen der wissenschaftlichen Erkenntnis einer Relativierung zu unterwerfen, die zusammenfassend als Hypothetisierung bezeichnet werden kann. Helmholtz entwickelte damit (...) schon im vergangenen Jahrhundert Ansätze einer Wissenschaftsauffassung , die in erstaunlichem Umfang in die Richtung der Moderne weisen. Wie nah er späteren Wissenschaftsauffassungen bereits gekommen ist, kann ein Vergleich mit Karl R. Poppers Forschungslogik illustrieren. In seiner Forschungslogik ist die Hypothetisierung der wissenschaftlichen Erkenntnis entschieden weiter vorangeschritten als in Heimholtz' Wissenschaftstheorie. Was sich bei Helmholtz erst vage abzuzeichnen beginnt, ist bei ihm bereits explizit formuliertes Programm geworden. Obwohl HeImholtz und Popper in keiner direkten wissenschaftstheoretischen Entwicklungslinie stehen und Popper sich in seinen Schriften auch nur sehr selten und beiläufig auf Helmholtz bezieht, finden sich dennoch überraschende und bisher nicht beachtete Berührungspunkte, die insbesondere dann hervortreten, wenn man Heimholtz' Wissenschaftsauffassung vor dem Hintergrund von Poppers Forschungslogik betrachtet.

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.

Článek se zabývá způsobem, jakým vnímá vztah vědecké metody a demokracie Karl Popper. Toto sepětí je jedním ze základních atributů Popperova myšlení. Pro jeho pochopení je třeba zasadit Poppera do historického kontextu vývoje liberálního myšlení a poukázat na možné souvislosti se Schumpeterovou redefinicí demokracie. Výchozím bodem je však interpretace základních episte- mologických předpokladů Popperova myšlení - konceptů provizornosti vědeckého poznání a ratio negativa. Primárním cílem článku je kontextualizace těchto předpokladů s politologickými a sociologickými důsledky. Ty lze spatřovat nejen (...) s odmítnutím positivismu a esencialismu, ale také v Popperově preferenci volebních a stranických systémů. Na závěr je rozpracována problematika kritického racionalismu, hodnot a otevřené společnosti na základě možných námitek vůči Popperově teorii. (shrink)

El presente trabajo intenta profundizar en la noción de racionalidad y la lógica de la situación de Karl Popper en el marco del debate entre “economía sustantiva” y “economía formal o instrumental”. Con tal propósito realizaremos una breve aproximación histórica al concepto de racionalidad económica señalando los distintos aportes de diversos autores a la cuestión. Este marco histórico permitirá encuadrar el planteo que Karl R. Popper hace de la lógica de la situación como metodología de las (...) ciencias sociales tomada de la teoría económica. En cuanto a la racionalidad y la lógica de la situación en Popper distinguiremos algunas notas acerca del análisis situacional y de la noción de racionalidad que subyace al mismo. Analizaremos el principio de racionalidad y el debate en torno al status epistemológico de tal principio. (shrink)

Bu çalışmada bilginin kazandığı doğru nitelemesi ve bilimsel bilgide doğrunun bir dogma haline gelmesi, kökenleriyle birlikte tartışılacaktır. Bu hususta Karl Popper'ın yanlışlamacı bilim imgesinin anlatıldığı bu çalışmada ikili bir yol izlenecektir. İlki; Popper'ın neye, neden karşı çıktığı üzerine, ikincisi ise bu karşı çıkış sonucunda açılan boşluğun nasıl doldurulduğudur. Dolayısıyla birinci aşama Popper açısından geleneksel imgeye yapılan bir kritik niteliğinde olurken, ikinci aşama ise Poppercı bilim imgesinin serimlendiği bölümü oluşturacaktır. Nihayetinde Popper yenilikleriyle bilimsel düşünüşe yeni bir (...) soluk getirirken, son bölümde sisteminin ne gibi eksiklikler barındırdığı tartışılacaktır. Bu eksiklikler ise Ayer ve Duhem-Quine tezi ile sırasıyla yanlışlamanın mantıksal olarak imkânsızlığı ve kuramın yanlışlanmasında holistik yaklaşımın gerekliliğini kapsayacaktır. (shrink)

A review of the volume that brings together K.R. Popper's writings on deductive logic and its foundations. I emphasize Popper's inferentialist position in his earlier articles and Carnap's influence on many of his logical ideas (an interesting letter from Carnap to Popper is also summarised in the review).

Abstract. Competition between developed and developing countries in developing the defense industry in the era of globalization has crossed the boundaries of a country's alliances. However, in the transfer of technology (ToT) process, it remains the object of domination by large countries, and developing countries remain confined in a rigid bureaucracy. Researchers offer a problem-solving approach to developing the defense industry experienced by developing countries. The researcher's first step describes the bureaucracy of developing countries, and then the researcher projects the (...) development of a strategy as a solution. The researcher realizes that the trial and error approach offered by Karl R. Popper demands further testing, so the researcher also explains the weaknesses of the solutions offered. The researcher concludes that the Problem-Solving approach can solve problems and anticipate problems. Problem-Solving is no longer seen as containing a simple method but an epistemology; Solutions appear before the problem itself appears. The researcher corrected the problem- solving position, as explained by Ian Angus, who moved from one line to a new line continuously. Researchers see not moving lines and continuing but reality entering a broader flow. (shrink)

This paper examines the differences and affinities between Karl Popper’s critical rationalism and Theodor Adorno’s critical theory through renewed attention to the original documents of their 1961 debate. While commentaries often describe the Popper-Adorno encounter as a theoretical disappointment, I reveal a confrontation between conceptually opposed programs of social research. Though both theorists are committed to critique as a political and epistemological struggle for human freedom, their conceptions of this struggle are starkly different. In the original seminar (...) papers, we find a conflict between critique as a practice of social rationality (Popper) and a critique of social rationality itself (Adorno). The versions of critical rationalism and critical theory meeting in this debate thus emphasize opposite dimensions of a reflexive practice of immanent critique. In closing, I suggest dissolving this conceptual tension by recovering the educational orientation of critique. (shrink)

Bilime ve onun bilgisine akademik, politik, ekonomik ve kamusal alanlar olmak üzere birçok alanda diğer bilgi iddialarına kıyasla daha fazla güven duyulmaktadır. Bilime duyulan bu güvenin temelinde büyük ölçüde bilimsel süreçlerin ve yöntemlerin nesnel bir şekilde yürütülmesi ve bu nesnel sürecin bir ürünü olarak bilimsel bilginin tarafsız bilim insanları tarafından ortaya konulduğu düşüncesi yatmaktadır. Bu bakımdan toplum tarafından bilimin tartışılmaz statüsünün ve bilimsel bilgiye verilen değerin belirleyicisi olarak nesnellik özelliği ön plana çıkmaktadır. Bilhassa doğa bilimleri söz konusu olduğunda bilimsel yöntemin (...) olgulara ve dış dünyaya ilişkin nesnel bilgiler sağladığı düşünülmektedir. Bu bakımdan doğa bilimleri, bilimde nesnelliğin paradigmatik örnekleri olarak kabul görmektedir. Beşeri ve sosyal bilimler alanında ise doğa bilimlerine kıyasla nesnellik algısı düşük olmasına rağmen, yöntemlerinin bilimsel yöntemle çalışılmaya uygun olmasından dolayı en azından ilke olarak nesnel olduğu değerlendirilmektedir. Bilimin değerler alanından ziyade olgu alanına ilişkin çalışmalar yürütmesi, bilim insanlarının değerler, anlamlar ve ideallerinden de kendisini izole ederek bilimsel nesnelliği temin edilebileceği konusunda genel bir kavrayışa yol açmaktadır. Bu görüşün önde gelen düşünürü Karl Popper’dır. Popper bilimsel nesnelliğin, olgusal içerikli önermelerin – protokol önermeleri – öznelerarası sınanabilir olması ile temin edilebileceğini ve böylece bilim insanlarının çalışmalarında kültür, değer ve inanç gibi öznel kanılarının bilimsel bilginin temellendirilmesi ve sınanması noktasında kullanılamayacağını ifade etmiştir. Ancak bilimin doğasına yönelik bir soruşturma bilimsel bilginin düşünüldüğü kadar nesnel bir sürece sahip olmadığını, bilim faaliyetini gerçekleştiren bilim insanlarının kişisel çıkarlarının, değerlerinin ve içinde yaşamış oldukları kültürel faktörlerin bilimsel bilginin elde edilmesi sürecinde etkili olabileceğini ortaya koymaktadır. Bu bakımdan bilimin doğasını doğru bir şekilde anlayabilmenin yolu bilimlerde nesnellik ölçütünün sosyolojik ve kültürel unsurlarla yakından ilişkili olduğunu bilmekten geçmektedir. Thomas Kuhn bilimsel değerlendirmelerde değer yargılarının ve kültürel unsurların kaçınılmaz olduğu düşüncesindedir. Kuhn, Popper’ın aksine sosyolojik etmen ve değerleri de işin içerisine katarak bir bilimsel nesnellik değerlendirmesi yapmaktadır. Bu doğrultuda, o bilimde fazlasıyla öznel unsurları vurguladığı eleştirilerine imkân vermeyecek şekilde bilim insanlarının takip etmesi gereken ve tavsiye niteliğinde olan belirli değerler neticesinde bilimsel nesnelliğin ve rasyonalitenin sağlanabileceğini ifade etmektedir. Bu kapsamda çalışmada, bilimin en bilinen özelliği olarak göze çarpan nesnellik kavramı ve düşüncesine yönelik kavramsal bir belirlemenin ardından kültür ve değer gibi sosyolojik unsurların bilimsel objektifliğin ayrılmaz bir parçası olduğu argümanı, Popper ve Kuhn’un çalışmaları göz önünde bulundurularak serimlenecektir.

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.

Na základě analýzy otázky, jak se učíme ze zkušenosti představuje studie problém indukce nejprve tak, jak byl formulován Humem skrze jeho příčinu v nezdůvodnitelnosti principu uniformity přírody. Následně ukazuje Popperovo řešení problému spočívající v naprostém odmítnutí induktivního usuzování. Popperův přístup je podroben srovnání s reliabilistickou pozicí Davida Papineau - stanoviskem, že poznání je pravdivým přesvědčením generovaným spolehlivou metodou. Hlavním cílem textu je znovuotevření diskuze nad tématem neplatnosti indukce a možná redukce námitek vůči její logické neplatnosti na základě nahlédnutí reliabilistického stanoviska. (...) Vedlejším záměrem je pak ilustrovat možné styčné body mezi kritickým racionalismem s jeho důrazem na delegitimizaci vědění a reliabilistickým kritériem spolehlivosti. (shrink)

Donald T. Campbell outlines an epistemological theory that attempts to be faithful to evolution through natural selection. He takes his position to be consistent with that of Karl R. Popper, whom he credits as the primary advocate of his day for natural selection epistemology. Campbell writes that neither he nor Popper want to give up the goal of objectivity or objective truth, in spite of their evolutionary epistemology. In discussing the conflict between an epistemology based on natural (...) selection and objective truth, Campbell cites an article by the German sociologist and philosopher Georg Simmel entitled 'On a Connection of Selection Theory to Epistemology', as presenting the issue in a notably forthright manner.The present essay summarizes Simmel's article, with the purpose of clarifying, in terms that Campbell apparently finds satisfactory, the conflict that Campbell acknowledges between an evolutionary epistemology and ultimate truth; the essay then examines the responses of Campbell and Popper to Simmel's position. While Campbell and Popper acknowledge the work of Simmel, their responses suggest something less than a full consideration of Simmel's position. (shrink)

Bilimi ve bilimsel bilgiyi kültür, değer ve öznel yargılardan izole ederek nesnel bir şekilde ortaya koyabilmeye yönelik hararetli tartışmaların yaşandığı yirminci yüzyıl bilim anlayışının temel gayesi, deney ve gözleme tabi olabilecek fiziki dünyadaki olguları, mantıksal çözümlemeye tabi tutarak birleştirilmiş bilime ulaşmaktır. Bu amaca giden yolda olgulara dayanmayan ve sınanamayan her türlü metafizik öge yok sayılır. Bilimsel bilginin sadece deney ve gözleme tabi olana, diğer bir deyişle olgu verilerine dayandığı iddiasını taşıyan bu düşünce sistemi, özellikle Viyana Çevresi üyeleri tarafından benimsenmiştir. Bu (...) bakımdan Çevre üyelerinin bilimsellik anlayışındaki temel ölçüt olgulara dayanan önermelerin ya da yargıların doğrulanabilmesidir. Bilimsel bilginin sadece olgusal dünyanın gözlemlenmesi ve bu gözlem sonucunda ortaya konulan önermelerin ya da ifadelerin doğrulanmasıyla sağlandığını düşünen Çevre üyelerinin bu savlarındaki amacı bilimi ve onun bilgisini her türlü kültür ve değer alanından uzaklaştırarak metafiziksel unsurlardan arındırılmış nesnel bilgiye ulaşmaktır. Çevre üyelerinin birçoğu bilim alanı içerisinde tartışmaya yol açan meselelerin aslında metafiziksel içerikli ve dolayısıyla bunların görünüşte problemler olduğunu belirterek bu tartışmaların bilimsel bilginin gelişimi önünde bir engel oluşturacağı kanaatindedir (Hızır, 1965, s. 254). Söz gelimi, Carnap’a göre, metafizik ögeler olgusal içeriğe sahip olmadığı ve sınanabilir nitelikte olmadıkları için bilim alanı içerisinde değerlendirilemez. Bu nedenle, metafizik ögeler hem doğrulanması mümkün olmadığı hem de dilin mantıksal dizimine genellikle uymadığı gerekçesiyle anlamsızdır (Öztürk, 2011, s. 155). Bu bakımdan Çevre üyelerine göre, olgulara dayanmayan ve bilimde yanılsamalara yol açan metafizik söylemler bilimden ayıklanmalı ve bilimsel bilgi ancak olgu ve deneye dayanan önermeler üzerinden yürütülmelidir. Öte yandan Çevre düşünürleri mantıksal çözümleme yoluyla olgulara dayanan önermelerin metafiziksel unsurlar içeren önermelerden ayırt edilebileceğini ifade etmiştir. Bu bağlamda metafizik önermeleri, metafizik olmayan önermelerden ayırt edecek ölçütün doğrulanabilirlik olduğunu savunurlar. Çevre üyelerinin bu tutumları bir bakıma bilim ve sözde bilim arasında ayrım yapma ve metafiziği bilimin dışında tutma çabası olarak da değerlendirilebilir (Kabadayı, 2011, s. 39-40). Yirminci yüzyıl bilim anlayışında bilimsel etkinlikte gözlemin ve gözlemi yürüten bilim insanlarının dolaysız öznel duyu verileriyle ilişkili olduğu bu nedenle gözlem verilerinin psikolojizmin etkisinde olduğu fikri ortaya atılır. Başta Neurath olmak üzere dönemin bilim felsefecileri bilimsel bilginin kültür, değer ve psikoloji gibi öznel unsurlardan uzaklaştığı sürece değerli olduğu kanısında olduğu için bu fikre karşı çıkmaktadır (Gillies, 2018, s. 123). Görüldüğü üzere, Çevre üyelerinin temel amacı metafizik önermelerden arındırılmış, olgulara dayanan bir bilime ulaşmaktır. Bu amacın gerçekleşmesine olanak sağlayacak yöntem ise mantıksal çözümlemedir. Bu bağlamda Çevre üyeleri olgulara dayanan ve doğrulanabilen önermelerin, söz dizimi (sentaks) ve anlamsal (semantik) açıdan incelemeye tabi tutulması gerektiğini düşünmektedir (Yardımcı, 2018, s. 13-15). Özellikle Carnap (1935, s. 9-10) doğrulamanın ancak öne sürülen önermenin mantıksal analize tabi tutularak yapılması gerektiğini iddia etmiştir (Irzık, 1962, s. 65). Bununla birlikte, felsefenin işlevi, önermeleri mantıksal analize tabi tutarak yalın hale getirmektir. İşte felsefenin bu yönü Neurath’da bilimin birliği, Carnap’ta ise bilimin sentaksı, yani bilimin mantığı üzerine çalışma anlamına gelir (Hızır, 1965, s. 252). Bilimi, bilim olmayandan ayırma yöntemi olarak kullanılan doğrulama işlemi, teorik bir söylem ve gözlem önermesi arasında yapılan bir işlem olması bakımından mantıksal ve dilsel bir özellik taşır. Buradaki temel sorun ise teorik bir önermenin gözlem önermelerine indirgenebilir nitelikte olması ve gözlem önermelerinin, gözlem ile nasıl ilişki kurduğunu saptamaktır. İşte Viyana Çevresi üyeleri bu ilişkinin protokol önermeleri ile kurulduğu kanaatindedir (Ural, 2012, s. 105-107) çünkü onlara göre; öznelerarası bir bilimin sağlanması için yansız ve anlam karmaşasından arındırılmış bir dil gereklidir (Serin, 2015, s. 55). Bu dil de ancak protokol önermeler aracılığıyla kurulabilir. Bu bağlamda Çevre üyelerinin, metafiziksel ifadeler barındıran önermelerin anlamsızlığı ve bilimleri ortak bir paydada birleştiren fiziksel bir dil oluşturma olmak üzere iki temel hedefinin olduğu söylenebilir (Godfrey-Smith, 2003, s. 25; Salgar, 2012, s. 187).

In Popper's Logik der Forschung, a theoretical system is a set of sentences that describe a particular sub-area of science, in particular of empirical science. The goal of axiomatizing a theoretical system is to specify a small number of "axioms" describing all presuppositions of the sub-area under consideration, so that all other sentences of this system can be derived from them by means of logical or mathematical transformations. The paper discusses two philosophical interpretations of these proper axioms. First, proper (...) axioms stipulate the use of the signs for the basic concepts of the system. Consequently, the proper axioms turn out to be analytic relative to a class of interpretations of the underlying logic. Hence, they cannot be falsified by refuting their logical consequences because these consequences are analytic as well. Secondly, proper axioms are synthetic, falsifiable and uncertain sentences. Hence, they are not immunized against falsification by refuting their logical consequences. (shrink)

The relation between body and mind is one of the oldest riddles that has puzzled mankind. That material and mental events may interact is accepted even by the law: our mental capacity to concentrate on the task can be seriously reduced by drugs. Physical and chemical processes may act upon the mind; and when we are writing a difficult letter, our mind acts upon our body and, through a chain of physical events, upon the mind of the recipient of the (...) letter. This is what the authors of this book call the 'interaction of mental and physical events'. We know very little about this interaction; and according to recent philosophical fashions this is explained by the alleged fact that we have brains but no thoughts. The authors of this book stress that they cannot solve the body mind problem; but they hope that they have been able to shed new light on it. Eccles especially with his theory that the brain is a detector and amplifier; a theory that has given rise to important new developments, including new and exciting experiments; and Popper with his highly controversial theory of 'World 3'. They show that certain fashionable solutions which have been offered fail to understand the seriousness of the problems of the emergence of life, or consciousness and of the creativity of our minds. In Part I, Popper discusses the philosophical issue between dualist or even pluralist interaction on the one side, and materialism and parallelism on the other. There is also a historical review of these issues. In Part II, Eccles examines the mind from the neurological standpoint: the structure of the brain and its functional performance under normal as well as abnormal circumstances. The result is a radical and intriguing hypothesis on the interaction between mental events and detailed neurological occurrences in the cerebral cortex. Part III, based on twelve recorded conversations, reflects the exciting exchange between the authors as they attempt to come to terms with their opinions. (shrink)

K. R. Popper distinguished between two main uses of logic, the demonstrational one, in mathematical proofs, and the derivational one, in the empirical sciences. These two uses are governed by the following methodological constraints: in mathematical proofs one ought to use minimal logical means (logical minimalism), while in the empirical sciences one ought to use the strongest available logic (logical maximalism). In this paper I discuss whether Popper’s critical rationalism is compatible with a revision of logic in the (...) empirical sciences, given the condition of logical maximalism. Apparently, if one ought to use the strongest logic in the empirical sciences, logic would remain immune to criticism and, thus, non-revisable. I will show that critical rationalism is theoretically compatible with a revision of logic in the empirical sciences. However, a question that remains to be clarified by the critical rationalists is what kind of evidence would lead them to revise the system of logic that underlies a physical theory, such as quantum mechanics? Popper’s falsificationist methodology will be compared with the recently advocated extension of the abductive methodology from the empirical sciences to logic by T. Williamson, since both of them arrive at the same conclusion concerning the status of classical logic. (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)

Karl Pfeifer attempts to present a coherent view of panentheism that eschews Pickwickian senses of “in” and aligns itself with, and builds upon, familiar diagrammed portrayals of panentheism. The account is accordingly spatial-locative and moreover accepts the proposal of R.T. Mullins that absolute space and time be regarded as attributes of God. In addition, however, it argues that a substantive parthood relation between the world and God is required. Pfeifer’s preferred version of panpsychism, viz. panintentionalism, is thrown into the (...) mix as an optional add-on. On this account, God is conceived of as a “spiritual field” whose nature can be made more intelligible by regarding “God” as having a mass-noun sense in some contexts. Pfeifer closes with the suggestion that we look to topology and mereology for further development of the position outlined in his paper. (shrink)

Karl Popper is famous for having proposed that science advances by a process of conjecture and refutation. He is also famous for defending the open society against what he saw as its arch enemies – Plato and Marx. Popper’s contributions to thought are of profound importance, but they are not the last word on the subject. They need to be improved. My concern in this book is to spell out what is of greatest importance in Popper’s (...) work, what its failings are, how it needs to be improved to overcome these failings, and what implications emerge as a result. The book consists of a collection of essays which dramatically develop Karl Popper’s views about natural and social science, and how we should go about trying to solve social problems. Criticism of Popper’s falsificationist philosophy of natural science leads to a conception of science that I call aim-oriented empiricism. This makes explicit metaphysical theses concerning the comprehensibility and knowability of the universe that are an implicit part of scientific knowledge – implicit in the way science excludes all theories that are not explanatory, even those that are more successful empirically than accepted theories. Aim-oriented empiricism has major implications, not just for the academic discipline of philosophy of science, but for science itself. Popper generalized his philosophy of science of falsificationism to arrive at a new conception of rationality – critical rationalism – the key methodological idea of Popper’s profound critical exploration of political and social issues in his The Open Society and Its Enemies, and The Poverty of Historicism. This path of Popper, from scientific method to rationality and social and political issues is followed here, but the starting point is aim-oriented empiricism rather than falsificationism. Aim-oriented empiricism is generalized to form a conception of rationality I call aim-oriented rationalism. This has far-reaching implications for political and social issues, for the nature of social inquiry and the humanities, and indeed for academic inquiry as a whole. The strategies for tackling social problems that arise from aim-oriented rationalism improve on Popper’s recommended strategies of piecemeal social engineering and critical rationalism, associated with Popper’s conception of the open society. This book thus sets out to develop Popper’s philosophy in new and fruitful directions. The theme of the book, in short, is to discover what can be learned from scientific progress about how to achieve social progress towards a better world. (shrink)

This view assumes that scientists have an objective attitude isolated from social factors in the process of obtaining scientific knowledge. In the second quarter of the twentieth century, the Vienna Circle and Popper argued that sociological and psychological elements can be seen in the context of discovery and that attempts to justify scientific theories and research are merely objective, epistemic studies. The claims regarding this distinction made under the context of discovery and the context of justification are interrupted by the arguments emphasized by Kuhn in his "The Structure of Scientific Revolutions" published in 1962. Kuhn opposes the distinction between discovery and justification by stating that social and psychological factors are present in both contexts. In this respect, Kuhn's conclusions are supported by the arguments put forward by the Strong Programme. (shrink)

Karl Popper (1902-1994) was one of the most influential philosophers of science of the 20th century. He made significant contributions to debates concerning general scientific methodology and theory choice, the demarcation of science from non-science, the nature of probability and quantum mechanics, and the methodology of the social sciences. His work is notable for its wide influence both within the philosophy of science, within science itself, and within a broader social context. Popper’s early work attempts to solve (...) the problem of demarcation and offer a clear criterion that distinguishes scientific theories from metaphysical or mythological claims. Popper’s falsificationist methodology holds that scientific theories are characterized by entailing predictions that future observations might reveal to be false. When theories are falsified by such observations, scientists can respond by revising the theory, or by rejecting the theory in favor of a rival or by maintaining the theory as is and changing an auxiliary hypothesis. In either case, however, this process must aim at the production of new, falsifiable predictions. While Popper recognizes that scientists can and do hold onto theories in the face of failed predictions when there are no predictively superior rivals to turn to. He holds that scientific practice is characterized by its continual effort to test theories against experience and make revisions based on the outcomes of these tests. By contrast, theories that are permanently immunized from falsification by the introduction of untestable ad hoc hypotheses can no longer be classified as scientific. Among other things, Popper argues that his falsificationist proposal allows for a solution of the problem of induction, since inductive reasoning plays no role in his account of theory choice. Along with his general proposals regarding falsification and scientific methodology, Popper is notable for his work on probability and quantum mechanics and on the methodology of the social sciences. Popper defends a propensity theory of probability, according to which probabilities are interpreted as objective, mind-independent properties of experimental setups. Popper then uses this theory to provide a realist interpretation of quantum mechanics, though its applicability goes beyond this specific case. With respect to the social sciences, Popper argued against the historicist attempt to formulate universal laws covering the whole of human history and instead argued in favor of methodological individualism and situational logic.

Karl Popper’s critique of idealism manifests itself with the application of his method, falsificationism, to metaphysics, epistemology, and social and political philosophy. According to Popper, who identifies himself as a philosophical realist, idealism has emerged as a result of the idea that reality cannot be known by reason and of the search for certainty which is erroneous, and it has begotten two mistaken and detrimental views. These views are historicism, the notion that history has an irresistible course, (...) and holism, the notion that social wholes are organic structures that amount to more than the individuals constituting them. Historicism and holism have become the philosophical underpinnings of closed societies throughout history, such as the totalitarian regimes of the 20th century. Therefore, with a practical leaning, Popper actually takes aim at these pernicious consequences of idealism while criticizing it. In this study, idealism and the contours of Popper’s philosophy are examined, and then Popper’s metaphysical, epistemological, social, and political critiques against idealism are investigated. Keywords: Karl Popper, idealism, historicism, holism, falsificationism. (shrink)

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

Karl Popper, ca raționalist critic, a fost un oponent al tuturor formelor de scepticism, convenționalism și relativism în știință. Multe dintre argumentele sale sunt îndreptate împotriva membrilor "Cercului Vienez". Popper este de acord cu aceștia cu privire la aspectele generale ale metodologiei științifice și neîncrederea lor în metodologia filosofică tradițională, dar soluțiile sale au fost semnificativ diferite. A contribuit semnificativ la dezbaterile privind metodologia științifică generală, demarcarea științei de pseudoștiință, natura probabilității și metodologia științelor sociale.

Karl Popper, as a critical rationalist, was an opponent of all forms of skepticism, conventionalism and relativism in science. A major argument of Popper is Hume's critique of induction, arguing that induction should never be used in science. But he disagrees with the skepticism associated with Hume, nor with the support of Bacon and Newton's pure "observation" as a starting point in the formation of theories, as there are no pure observations that do not imply certain theories. (...) Instead, Popper proposes falsifiability as a method of scientific investigation. DOI: 10.13140/RG.2.2.11481.36967 . (shrink)

Karl Popper a propus falsificabilitatea ca un criteriu important în diferențierea dintre știință și pseudoștiință. El susține că verificarea și confirmarea nu pot juca niciun rol în formularea unui criteriu satisfăcător de delimitare. În schimb, propune ca teoriile științifice să se deosebească de teoriile ne-științifice prin pretenții testabile pe care viitoarele observații le-ar putea dezvălui a fi false. Popper atrage atenția asupra faptului că teoriile științifice sunt caracterizate prin existența unor falsificatori potențiali - declarații care ar putea (...) fi descoperite ca fiind false.

A brief intellectual biography of Sir Karl Popper.

Bu makalede, bilim felsefecisi kimliğiyle tanınan Thomas Kuhn’un eğitim ve özellikle fen eğitimi alanındaki görüşlerine değinilmektedir. Fen eğitimi, bilim, bilimin doğası ve bilim uygulamaları hakkında düşünceler geliştirmeye odaklanarak fen öğrenimi için gerekli olan beceri ve anlayışın geliştirilmesini amaçlamaktadır. Fen eğitiminin temel amaçlarından biri bilimin gerçek doğasının tespit edilmesi ve bu doğrultuda bir eğitim modelinin belirlenmesidir. Bu çerçevede Kuhn’un bilim tarihine yönelik incelemeleri neticesinde ileri sürdüğü paradigma kavramı bilimin doğası ve fen eğitimi konusundaki görüşlerin değişimine yol açmıştır. Kuhn açısından fen eğitimi (...) yürürlükteki bilim yapma tarzının temelinde yatan paradigma ve öğretilerinin bilim insanlarına ve öğrencilere aktarılması sürecidir, bu nedenle fen eğitimi yalnızca olağan bilim döneminde mümkündür. Kuhn’un eğitim modeli, mevcut paradigmayla ilişkili olarak karşılaşılan bulmaca ya da sorunları çeşitli örneklerden hareketle tekrar tekrar çözmeye çalışan öğrenciler aracılığıyla gerçekleştirilir. Kuhn’un olağan bilimin sınırları içerisinde kalarak değerlendirdiği fen eğitimi anlayışı eleştirel düşünceyi engellediği iddiasıyla Karl Popper, John Watkins ve Richard Bailey tarafından katı, tutucu, dogmatik ve endoktrinasyonu vurgulayan bir eğitim anlayışı olarak görülmektedir. Bu çerçevede makalede, öncelikli olarak Kuhn’un bilimin doğası ve bilimin gelişim tarzına yönelik belirlemeleri doğrultusunda fen eğitimine yönelik düşünceleri ve bu düşüncelerin eğitim alanındaki yansımaları incelenmektedir. Ardından, Kuhn’un fen eğitimi üzerine görüşlerinin iddia edildiği gibi dogmatik bir yapıda olmadığı, endoktrinasyonu ya da zorla öğretimi vurgulamadığı, bu tür yorumların radikal bir yaklaşımdan öteye gidemediği ileri sürülmektedir. Son olarak makalede, Kuhn’un fen eğitimi anlayışının yalnızca bir durum tespiti ya da bir fen eğitimi tasviri olarak değerlendirilmesi gerektiği düşüncesi ön plana çıkarılmaktadır. -/- In this article, Thomas Kuhn’s impact, who is known as a philosopher of science, on science education are mentioned. Science education aims to develop the skills and understanding necessary for science learning, with a focus on developing ideas about science and the nature of science. One of the main purposes of science education is to determine the true nature of science and to determine an education model in this direction. In this context, the concept of paradigm, which Kuhn put forward as a result of his studies on the history of science, has led to a change in views on the nature of science and science education. For Kuhn, science education is the process of conveying the paradigm underlying the current way of doing science to scientists and students because science education is possible only in the normal science period. Kuhn’s educational model is carried out through students who repeatedly try to solve puzzles or problems encountered in relation to the current paradigm. Kuhn’s understanding of science education is seen by Karl Popper, John Watkins and Richard Bailey as a rigid, conservative, dogmatic and indoctrinational education approach with the claim that it prevents critical thinking. In this context, the article primarily examines Kuhn’s thoughts on science education and the reflections of these thoughts in the field of education. Then, it is argued that Kuhn’s views on science education are not dogmatic as claimed, he does not emphasize indoctrination, and that such interpretations cannot go beyond a radical approach. Finally, in the article, it is emphasized that Kuhn’s understanding of science education should be evaluated only as a description of science education. (shrink)

Natural science, properly understood, provides us with the methodological key to the salvation of humanity. First, we need to acknowledge that the actual aims of science are profoundly problematic, in that they make problematic assumptions about metaphysics, values and the social use of science. Then we need to represent these aims in the form of a hierarchy of aims, which become increasingly unproblematic as one goes up the hierarchy; as result we create a framework of relatively unproblematic aims and methods, (...) high up in the hierarchy, within which much more problematic aims and methods, low down in the hierarchy, may be improved as scientific knowledge improves. Then, we need to generalize this hierarchical, aims-and-methods-improving methodology so that it becomes fruitfully applicable to any worthwhile endeavour with problematic aims. Finally, we need to apply this methodology to the immensely problematic task of making progress towards as good a world as feasible. (shrink)

In this essay, the problem of violence, its causes, and how eternal peace in a society can be attained shall be discoursed. Violence is illegitimate torture which may be either psychological or physical. Mostly violence is the product of irrational actions which cause destruction in society. Reason is the only solution to the problem of violence. In the paper, I will use Karl Popper’s theory of Critical Rationalism to argue that rational deliberation can resolve the conflicts which often (...) cause violence in society. The practice of unreason primarily causes violence in society which is one of the gravest hindrances to human development. For example, in Pakistani society, an orthodox mind easily gets inclined toward intolerant behavior. The first and foremost aim of this thesis will be to give a proper analysis of why unreason occurs in society. Secondly, it will attempt to propose a viable solution to the problem of violence. However, it will also consider the alternative solutions presented by other theorists. In this regard, Karl popper’s theory of Critical Rationalism could be promising. Being a problem-oriented philosopher, Popper argues that societies advance through trial and error underpinning critical rationality. (shrink)

Those who turn to phenomenological psychopathology as an answer to problems in psychiatric healthcare may find a philosophical tradition rooted in the early-mid 20th century that has done little to adapt to modern ideas in psychiatric healthcare and psychiatric research. The Renewing Phenomenological Psychopathology project, funded by the Wellcome Trust and led by Professor Matthew Broome and Professor Giovanni Stanghellini, calls for reflection, revitalization and reconstruction of this discipline, diversifying global scholarship and working with lived experience scholars, so that it (...) can pave new paths in psychiatric understanding. The contributions of the current special issue aim to breathe new life into a vital method in psychopathology and to chart its future trajectory. (shrink)

This study investigates the significant relationship between procrastination and academic burnout among first-year college students. Employing correlational design and standardized tests, the statistical analysis reveals that the r coefficient of 0.33 indicates a low positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to the decision to reject the null hypothesis. Hence, a significant relationship exists between procrastination and academic burnout among college students.

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)

Classically, Christians have professed the saving efficacy of the cross. Does Karl Rahner? Recent commentary on Foundations of Christian Faith has described Rahner as conflating “atonement” generally with penal substitutionary theories of a changing God, as ruling out the redemptive significance of Christ’s death, and as denigrating the normativity of Scripture in order to do so. This article responds to these claims, unfolding Rahner’s soteriology and arguing that he advances a theology of the cross which affirms its saving efficacy, (...) including in the last decade of his work.

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

Karl Popper, en tant que rationaliste critique, a été un opposant à toutes les formes de scepticisme, de conventionnalisme et de relativisme scientifique. En 1935, il a écrit Logik der Forschung. Zur Erkenntnistheorie der modernen Naturwissenschaft, traduisant plus tard le livre en anglais et le publiant sous le titre The Logic of Scientific Discovery (1959), considéré comme un travail de pionnier dans son domaine. De nombreux arguments de ce livre sont dirigés contre les membres du « Cercle de (...) Vienne », tels que Moritz Schlick, Otto Neurath, Rudolph Carnap, Hans Reichenbach, Carl Hempel et Herbert Feigl. Popper est d'accord avec eux sur les aspects généraux de la méthodologie scientifique et sur leur méfiance à l'égard de la méthodologie philosophique traditionnelle, mais ses solutions ont été sensiblement différentes. Popper a largement contribué aux débats sur la méthodologie scientifique générale, la démarcation de la pseudo-science, la nature des probabilités et la méthodologie des sciences sociales.

According to Karl Popper, science cannot verify its theories empirically, but it can falsify them, and that suffices to account for scientific progress. For Popper, a law or theory remains a pure conjecture, probability equal to zero, however massively corroborated empirically it may be. But it does just seem to be the case that science does verify empirically laws and theories. We trust our lives to such verifications when we fly in aeroplanes, cross bridges and take modern (...) medicines. We can do some justice to this apparent capacity of science to verify if we make a number of improvements to Popper’s philosophy of science. The key step is to recognize that physics, in accepting unified theories only, thereby makes a big metaphysical assumption about the nature of the universe. The outcome is a conception of scientific method which facilitates the criticism and improvement of metaphysical assumptions of physics. This view provides, not verification, but a perfect simulacrum of verification indistinguishable from the real thing. (shrink)

Sulla base di un'analisi della biblioteca di Karl Popper, la "Karl Popper collection" di Klagenfurt in Austria, argomento che le letture e i commenti di questo grande pensatore del Novecento testimoniano un uso dell'autocritica e del confronto come strumento di crescita della conoscenza umana.

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.

Suporterii lui Popper au susținut că cele mai multe critici se bazează pe o interpretare neînțeleasă a ideilor sale. Ei afirmă că Popper nu ar trebui interpretat în sensul că falsificabilitatea este o condiție suficientă pentru delimitarea științei. Unele pasaje par să sugereze că el o consideră doar o condiție necesară. Alte pasaje ar sugera că, pentru ca o teorie să fie științifică, Popper impune (pe lângă falsificabilitate) și alte teste, și că rezultatele negative ale testelor sunt (...) acceptate.

În această lucrare argumentez faptul că, în ciuda criticilor teoriei falsificabilității propuse de Karl Popper pentru demarcarea între știință și ne-știință, în principal pseudoștiință, acest criteriu este încă foarte util, și perfect valabil după perfecționarea lui de către Popper și adepții lui. Mai mult, chiar și în versiunea sa inițială, considerată de Lakatos ca ”dogmatică”, Popper nu a afirmat că această metodologie este un criteriu absolut de demarcare: un singur contra-exemplu nu este suficient pentru a falsifica (...) o teorie; mai mult, o teorie poate fi salvată în mod legitim de falsificare prin introducerea unei ipoteze auxiliare. În comparație cu teoria lui Kuhn a revoluțiilor, de care el însuși s-a dezis ulterior transformând-o într-o teorie a ”micro-revoluțiilor”, consider că metodologia de demarcare a lui Popper, împreună cu dezvoltarea ulterioară propusă de acesta, inclusiv coroborarea și verosimilitudinea, deși imperfectă, nu numai că este valabilă și azi, dar este încă cea mai bună metodologie de demarcare. Pentru argumentare, m-am folosit de principalele lucrări ale lui Popper care tratează această problemă, și a principalilor săi critici și susținători. După o scurtă prezentare a lui Karl Popper, și o introducere în problema demarcației și metodologia falsificabilității, trec în revistă principalele critici aduse și argumentele susținătorilor săi, accentuând pe ideea că Popper nu a pus niciodată semnul egalității între falsificare și respingere. În final prezint propriile concluzii în această problemă. -/- DOI: 10.58679/TW55590. (shrink)

Despite the criticism of Karl Popper's falsifiability theory for the demarcation between science and non-science, mainly pseudo-science, this criterion is still very useful, and perfectly valid after it was perfected by Popper and his followers. Moreover, even in his original version, considered by Lakatos as "dogmatic", Popper did not assert that this methodology is an absolute demarcation criterion: a single counter-example is not enough to falsify a theory; a theory can legitimately be saved from falsification by (...) introducing an auxiliary hypothesis. Compared to Kuhn's theory of revolutions, which he himself later dissociated from it transforming it into a theory of "micro-revolutions," I consider that Popper's demarcation methodology, along with the subsequent development proposed by him, including the corroboration and the verisimilitude, though imperfect, is not only valid today, but it is still the best demarcation methodology. For argumentation, I used the main works of Popper dealing with this issue, and his main critics and supporters. After a brief presentation of Karl Popper, and an introduction to the demarcation problem and the falsification methodology, I review the main criticisms and the arguments of his supporters, emphasizing the idea that Popper has never put the sign of equality between falsification and rejection. Finally, I present my own conclusions on this issue.

Whether defended or criticized, Darwinism is generally considered a scientific theory. However, Popper contests this point. According to him, Darwinism (defined as the explanation of evolution by natural selection) is less a scientific theory than a metaphysical research program: a theoretical framework that has a heuristic function for science, but that does not fulfill the necessary condition for any science, namely testability. In terms of deconstructing Darwinism, Popper’s position is therefore interesting. It raises the question of the scientificity (...) of Darwinism. More generally, it raises the question of the scientificity of the debate on the mechanisms of evolution: what type(s) of argument(s) does this debate bring into play? Can this debate be reduced to an opposition between a scientifically founded theory (Darwinism) and other theories of evolution that are purely philosophical, or even ideological? First, I analyze Popper’s position. According to him, Darwinism is rationally defensible, but difficult to test because it is not capable of making precise and sufficiently specific predictions. Darwinism is therefore more metaphysical than scientific, even if it has a heuristic function for science. Moreover, Popper proposes an improvement of Darwinism by asserting that it must give a more important place to the activity of organisms in evolution. In a second step, I discuss Popper’s position, taking into account the criticisms that this position has generated. As regards the non-testability of Darwinism, it appears that the tests proposed in the literature do not meet the defects pointed out by Popper. On the metaphysical character of Darwinism, I discuss Popper’s assertion on two levels: on the possibility of a clear demarcation between science and non-science, and on the value of the demarcation criterion proposed by Popper. Finally, on the improvement of Darwinism, I attempt to underline the originality of the Popperian proposal. (shrink)

Philosophy of science is seen by most as a meta-discipline – one that takes science as its subject matter, and seeks to acquire knowledge and understanding about science without in any way affecting, or contributing to, science itself. Karl Popper’s approach is very different. His first love is natural philosophy or, as he would put it, cosmology. This intermingles cosmology and the rest of natural science with epistemology, methodology and metaphysics. Paradoxically, however, one of his best known contributions, (...) his proposed solution to the problem of demarcation, helps to maintain the gulf that separates science from metaphysics, thus fragmenting cosmology into falsifiable science on the one hand, untestable philosophy on the other. This has damaging repercussions for a number of issues Popper tackles, from the problem of induction to simplicity of theory and quantum theory. But his proposed solution to the demarcation problem is untenable. Metaphysical assumptions are an integral part of scientific knowledge, inherent in the persistent acceptance of unified theories against the evidence. Once this is appreciated, it becomes obvious that natural philosophy, a synthesis of science and philosophy, is both more rigorous and of greater intellectual value than the two dissociated components we have today. What Popper sought for could come to full fruition. Problems that Popper tackled, from the problem of induction, to the problem of unity of theory, problems of quantum theory, and problems concerning the scope and limits of physics, all receive more adequate resolution within the new, fully-fledged natural philosophy.

Neopositivistic philosophers held that Popper's destructive criticism to inductive methods is wrong. The legend according to which Popper's criticism, in the final analysis, is inconsistent is greatly widespread also amongst neopositivistic Italian scholars. I argue that they are wrong, and that, in general, Popper's view about induction is true. According to Popper all scientific concepts are theoretical, for every assertion not only entails hypotheses but it is also hypothetical, that is not sure and always falsifiable. I (...) argue that the validity and the strength of Popper's criticism to induction is independent from the view according to which all scientific concepts are theoretical. (shrink)

It is an irony to attack a more sceptical epistemology than one's own in the name of scepticism and defend, instead, an epistemology that is positively illogical. And yet that is what Martin Gardner has done in his “A Skeptical Look at Karl Popper.”.
