Popper and Other Philosophers

In this paper, I set out to critically review the impact of Popperian falsificationism and Lakatosian methodology of scientific research programmes [MSRP] on economic methodology and philosophy of economics. The central thesis I maintain is that neither Popper's falsificationism nor Lakatos' MSRP offers [philosophy of] economics a proper condition for the reception or rejection of economic theories.

L’article de Karl Popper « Indeterminism in Quantum Physics and in Classical Physics » est tombé injustement dans l’oubli. Popper jugeait le déterminisme faux : l’avenir est ouvert. En principe, remplacer la variante de Laplace de la pré-détermination par une prédétermination prévisible permet de rendre scienti-fique, donc réfutable, le déterminisme « scientifique ». Popper a affirmé qu’il l’avait réfuté. Maintenant, un système métaphysique peut avoir une extension – au sens mathématique – qui le rend explicatif et testable. Si une extension (...) existe, alors elle n’est pas unique, et de nombreuses autres extensions alterna-tives existent. La preuve de Popper n’est alors pas concluante. (shrink)

Karl Popper’s “Indeterminism in Quantum Physics and in Classical Physics” suffers unjust neglect. He judged determinism false: the future is open. In principle, replacing Laplace's variant of predetermination with predictable predetermination renders “scientific” determinism scientific and so refutable. Popper claimed that he had refuted it. Now a metaphysical system may have an extension—in the mathematical sense—that may render it explanatory and testable. If it exists, then it is not unique but has many alternative extensions. Popper’s proof is then inconclusive.

The objective of this work is to present Ludwig Wittgenstein's perspective on the impossibility of the existence of philosophical problems, to then reflect on the implications of such a perspective based on Popper's thought. For that, Wittgenstein's perspective, as exposed in his work Tractatus logico-philosophicus, is contrasted with Karl Popper's perspective presented in “The nature of philosophical problems and their scientific roots” (in Conjectures and refutations). The example of the problem faced by Kant in his work Critique of pure reason (...) will also be considered for the analysis of Wittgenstein's argument. According to Wittgenstein, philosophical problems are pseudo-problems because they have no solution. However, despite admitting the existence of pseudo-problems, Popper argues that factual, logical, or hybrid problems, under certain circumstances, can be philosophical. Thus, the aim is to contrast these two perspectives in order to emphasize how not all philosophical problems are pseudo-problems. (shrink)

20. yüzyılın önemli bilim felsefecisi Lakatos'un, bilim felsefesinde getirmiş olduğu yeni bakış açısı ve yöntem tartışmasıyla ayrıcalıklı bir konumu bulunmaktadır. Bilimin yapısı ve işleyişinin anlaşılması için bilim tarihinin iyi bilinmesi gerektiği belirten düşünür, bilimsel bilginin bilimsel olmayandan ayırt edilmesi hususunda var olan bilimsellik ölçütlerine eleştiriler getirerek kendi sınır çizme ölçütünü belirlemiştir. Buna bağlı olarak Bilimsel Araştırma Programı aracılığıyla bilimsel rasyonalitenin nasıl geliştiği konusuna da açıklık getirmeye çalışmıştır. Onun düşünsel arka planında, bilim felsefesinde fikirleriyle önemli yer edinmiş Viyana Çevresi, Popper ve (...) Kuhn gibi düşünürler ve onların bilimsellik, rasyonalite gibi temel problemlere yönelik çeşitli çözüm önerileriyle geliştirdikleri kuramları bulunmaktadır. Viyana Çevresi'nin olgusal temelli doğrulamacılığa dayanan bilim anlayışına eleştiriler yönelterek, Popper'ın bilimsellik ölçütü olan yanlışlamacılığı "dogmatik", "metodolojik" ve "sofistike" yanlışlamacılık şeklinde analiz eden Lakatos, bu analizini Kuhn'un bilimsel devrimler ile geliştirdiği tarih tasarımı ile sentezlemeye çabalamıştır. Bu çalışmada, Lakatos'un bilimsel metodolojisi için öne sürdüğü yeni çözüm önerisi bağlamında kendinden önceki bilimsel görüşlere yönelik eleştirilerini incelemek, bilim anlayışının bilim felsefesi açısından önemini belirlemek ve bilimsel yöntem sorunu üzerine düşüncelerini irdelemek amaçlanmaktadır.

In this paper I defend the claim that Paul Feyerabend held a robust metaphilosophical position for most of his philosophical career. This position I call Decision-Based Epistemology and reconstruct it in terms of three key components: a form of epistemic voluntarism concerning the justification of philosophical positions and a behaviorist account of philosophical beliefs, which allows him to cast normative arguments concerning philosophical beliefs in scientific methodology, such as realism, in terms of means-ends relations. I then introduce non-naturalist and naturalist (...) variants of his conception of normativity, which I trace back to his mentors Viktor Kraft and Karl Popper, respectively. This distinction, introduced on the metaphilosophical level, can can be put to use to explain key changes in Feyerabend’s philosophical proposals, such as the viability of his methodological argument for realism. I conclude that this Decision-Based Epistemology should be further explored by historically embedding Feyerabend’s metaphilosophy in a voluntarist tradition of scientific philosophy. (shrink)

Through his phenomenological approach, Husserl criticized the situation of science and called it a crisis. He aimed to suggest a way out of this crisis by presenting a philosophical program. However, restoring philosophy to its ancient unifying situation, saving science from this crisis, and giving it a human face, requires, according to critical rationalism, to consider the objectivity and rationality of science. Ignoring these considerations puts science on an incorrect and inconvenient path. These considerations require a revision of Husserl’s essentialism (...) and justificationsim, and placing truth as the aim of science. (shrink)

Essentialism is one of the common approaches in the philosophy of technology. Based on this approach, technology has an independent essence, and knowing technology requires knowing this essence. The present article aims to criticize essentialism in the philosophy of technology in the framework of critical rationalism. The paper argues that essentialism is inadequate because it leads to irrationalism and determinism and destroys any ground for reform and critical discussion about technology; instead, it recommends sudden and irrational changes. Secondly, it contains (...) some presuppositions and false doctrines about the evolution of technology and its relation to humans. We will also explain that essentialists’ recommendation to take refuge in art or hold a free relationship towards technology is inconclusive in facing technological inconveniences. Instead, local considerations should be taken into account in the modification process, and they should be carried out piecemeal and in a critical context. (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”.

A review of Steven Fuller's excellent book. Steve Fuller, professor of sociology at the University of Warwick, argues that, unfortunately for science, Kuhn won this debate. In the wake of Kuhn, science has come to be justified more by its paradigmatic pedigree than by its progressive aspirations. In other words, science is judged by whatever has come to be the dominant scientific community.

Lakatos's methodology, if analysed as belonging to the demarcationist-rationalist program launched by Popper gives some interesting conclusions concerning the feasibility of the project: (1) Rationalism cannot provide arguments against relativism. (2) A theory of scientific rationality cannot be defended without relying on scientific authorities. (3) A historical justification of scientific rationality does not show that the procedures that are rational according to the theory are truth-conducive.

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 plural for knowledge, “knowledges” fell out of use in English philosophical discourse at the end of the Seventeenth Century. This paper reflects on the potential significance of this in the development of theoretical approaches to epistemology from the writings of John Locke to Karl Popper and the present day.
