In September 2007, more than 100 philosophers came to Prague with the determination to approach Karl Popper's philosophy as a source of inspiration in many areas of our intellectual endeavor. This volume is a result of that effort.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Academic Skepticism in Hume and Kant: A Ciceronian Critique of Metaphysics by Catalina González QuinteroZuzana ParusnikováCatalina González Quintero. Academic Skepticism in Hume and Kant: A Ciceronian Critique of Metaphysics. Cham: Springer, 2022. Pp. 268. Hardcover. ISBN: 978-3-030-89749-9. £99.99.This book is a valuable contribution to the rapidly expanding field of research into the formative impact of ancient skepticism on early modern philosophy. This new paradigm was introduced several decades (...) ago, as González Quintero acknowledges, by the pioneering work of Richard Popkin; and while Popkin emphasized the constitutive role of Pyrrhonism in this process, recent philosophical debates have been characterized by a more measured approach, carefully differentiating between the Academics and the Pyrrhonists, and their respective influence on modern skeptics. Gonzáles Quintero opts for the Academic interpretation of Hume’s skepticism, applying it to both his Treatise and the first Enquiry, and extending it to both of Kant’s Critiques—an area much less explored in the context of ancient skepticism. She thus heads into a complex philosophical landscape.The reader may be somewhat puzzled by the book’s subtitle, one which seems to add yet another theme to its already broad structure. However, as Gonzáles Quintero explains in the Introduction, she wants to take the discussions of Academic skepticism beyond the field of empirical science and concentrate on the attitude of the skeptics towards metaphysics; her aim is to show how Cicero, Hume, and Kant “used skeptical means to examine the justification of metaphysical claims and to determine, in this way, which resulting beliefs could be held non-dogmatically and for practical purposes” (1). Perhaps then, the book may be more accurately titled Academic Skepticism and Metaphysics: Cicero, Hume and Kant.Though this may seem a reduction in the scope of the topics, in this particular case it is an expansion, since the author reconstructs how the attitude of the skeptics to metaphysics unfolds from their general epistemological skepticism concerning the limits of reason. She divides the book into three main parts (Cicero, Hume, and Kant), with the first chapter of each part describing the skeptical method of that particular philosopher or school, and the second examining its application to metaphysical matters. This is a huge undertaking for one book, requiring the author to navigate a vast field of philosophical material, including a significant amount of primary and secondary literature, while turning it all back toward the main question concerning the role played by Academic (Carneadean) skepticism in the ancient, Humean, and Kantian treatments of religion and other metaphysical issues. The danger of topic-overload arises and a selective approach is crucial to avoid “dropping the ball.” Gonzáles Quintero tackles this task with varying success. [End Page 346]The first chapter of the first part of the book provides a thorough analysis of Academic skepticism and how it differs from Pyrrhonism and stoicism. With an extensive knowledge of scholarly debates on ancient skepticism, the author discusses various nuances in the relationship between radical Pyrrhonism and Arciselaus of the Second Academy, moving on, predictably, to Carneades of the Third Academy, who proposed a moderate version of skepticism based on evaluating the degree of persuasiveness of impressions. Such impressions deserve non-dogmatic approval and can thus reduce the scope of epoché; they motivate our search for truth while admitting our fallibility; and they guide us in practical matters. Her argument that assenting to persuasive beliefs contains a rational (normative) aspect perhaps deserves further discussion; for the ancient skeptics the criterion of persuasiveness was subjective and unstable, reflecting our momentary feelings about appearances.In the chapter on metaphysics, the author compares Cicero’s skeptical method in De Natura Deorum (DND) and the Tusculan Disputations. In the former, Cicero (through the character of Cotta) abandons skeptical principles (which would prevent us from defining the nature of the gods) for the sake of the practical usefulness of religious rituals as endorsed by the Stoics; while for the Epicureans (Velleius) the gods (or some cosmic Deity) are utterly unconcerned by our world, for the Stoics (Balbus) they care about human affairs—thus this latter stance supports the state religion that Cicero...

Popper proposed his theory of objective knowledge to eliminate subjectivist epistemologies. Popper’s objectivism culminated in the theory of the autonomous World 3 characterized by its independence from the subjective factors belonging to World 2. I argue that Popper did not succeed in unifying his idea of the autonomy of knowledge with the requirement of the creative role of the critical subject in cognition. Moreover, his effort to desubjectivize knowledge undermined the vital importance of the critical activity that ensures the dynamism (...) of the growth of knowledge. In this respect, Popper suppressed the most interesting feature of his philosophical contribution. (shrink)

Semmelweis’ discovery of the etiology of childbed fever has long attracted the attention of historians of medicine and biographers. In recent years it has also become of increasing interest to philosophers. In this paper I discuss the interpretation of Semmelweis’ methodology from the viewpoint of the inference to the best explanation and argue that Popperian methodology is better at capturing the dynamics of the growth of knowledge. Furthermore, I criticize the attempts to explain the failure of Semmelweis to have his (...) discovery accepted on the basis of the Kuhnian concept of paradigms, and warn that this view may endorse dogmatism as the norm The Kuhnian position also raises the problem of the authoritarian nature of scientific institutions which defend a paradigm against unorthodox, rebellious views, such as in the case of Semmelweis. Popperian philosophy is seen as a challenge to promote a link between an open society and open science with its main aim being to cherish a free critical spirit. (shrink)

At various occasions Popper states that in order for a theory to show its strength “certain amount” of dogmatism must precede the critical testing phase. He even argues that dogmatism is a necessary precondition of criticism. These are alarming statements, undermining Popper’s methodological imperative of falsification. Critical rationalism is based on a strict opposition to dogmatism for logical reasons, for evolutionary reasons, and for ideological reasons. Popper cannot provide any objective criterion defining the proper dosage of dogmatism and thus opens (...) doors to its uncontrolled expansion. Criticism thus ceases to be the non-negotiable normative principle and the inviolable standard of rationality. (shrink)

Hume built his philosophical system with the ambition to become a Newton of human nature. His science of man is the fulfillment of this project. Hume was inspired by the Newtonian experimental empirical method excluding hypotheses, and he applied this method to moral sciences; he took those to be the basis of all other knowledge. The observation of human cognitive faculties, however, brought him to sceptical conclusions concerning the rational justification of empirical sciences. His original ambitions are thus undermined and (...) his scepticism leads to the loss of legitimacy of natural science. The core of Hume's science of man is twofold - it consists in the analysis of mind and of human social behaviour. Hume contributed to the development of psychology and helped to form social sciences as a specific research area. Following his empirical method based on observation, his science of man has rather a documentary role than any normative features. (shrink)

Debata o tzv. „Novém Humovi“ byla v posledních desetiletích dominantním tématem humovské interpretace. James Hill ve svém příspěvku v tomto časopise podporuje hlavní požadavek „novohumovců“, který vymezuje Huma jako epistemologického skeptika a ontologického realistu. Vůči tomuto pojetí máme několik výhrad. Některé se týkají nejasností v definici realismu a celkově i smysluplnosti projektu „Nový Hume“. Některé se týkají konkrétních Hillových argumentů zaměřených na Humovy Dialogy a především jeho tvrzení, že v tomto díle lze nalézt další důkaz Humova realismu.

In lieu of an abstract, here is a brief excerpt of the content:Against the Spirit of Foundations: Postmodernism and David Hume1 Zuzana Parusnikova Introduction David Hume lived at the very dawn ofthe modern age and belonged to the Scottish Enlightenment. The Enlightenment is often conceived of as the essence of modernity, thus standing in firm opposition to postmodernism. According to postmodernists, the Enlightenmentideal of a universal liberating rationality and the principle of universally shared norms ofhumanism have not only lost their (...) vigour and appeal, but have proved to be oppressive and downright authoritarian. The project of the Enlightenment should thus be abandoned. And yet, despite the fact that Hume chronologically belonged to modernity, I find striking similarities between his views and postmodernism. Over the years there have been many, typically modern, efforts to find some unity and to grasp the essence of Hume's philosophy, to provide some general interpretative angle by which it can appear as a consistent philosophical system. I want to argue that such an approach is neither necessary nor desirable because it deprives Hume's philosophy of its most appealing feature—his acceptance of and tolerance towards the irreconcilability of its sceptical and natural elements. There is no need to force Hume to fit neatly under any traditional philosophical label.2 The permanent inconsistency in his 'system' resulting from his firm anti-foundationalist attitude is not a defect but instead makes his philosophy far more intriguing. The disunity which can be found in Hume's texts is also the feature bringing him close to postmodernism. Postmodernism is a fuzzy area, difficult to approach let alone to define. It deliberately avoids defining itself and could even be seen as "the characteristic of a universe where there are no more definitions possible." 3 Postmodernism is not a homogeneous stage of thinking following after modernism (as the prefix 'post' misleadingly suggests), but rather deconstructs modernity without offering a new and coherent alternative. Therefore, paradoxically, while deconstructing we have to use thevocabularywhichis being deconstructed and cannotcompletely avoid the ' logos ofthe definition'. This feature is reflected in what Derrida calls 'writing under erasure': we write and erase at the same time—since our language is constructed upon the modern logocentrism, we have no choice but to Volume XLX Number 1 ZUZANA PARUSNIKOVA use it. As a result, interpreting the meaning of texts, although authoritarian in its original intention, reveals the illusory character of any ultimate interpretation. Texts are viewed as mysterious and confusinglabyrinths,bycontrasttothemodernobsession aboutclarity, precision, consistency and the possibility of decoding the exact, fundamental message they convey. Philosophy is no longer conceived ofas a questfor foundations, and philosophical texts are looked at from a new perspective: they are rather 'misread', 'misinterpreted' or read on the margins' in order to paralyse the oppressive interpretations seeking some foundational interpretative principle and imposing compulsory norms ofunderstanding.4 Hume's philosophy has suffered extensive abuse of this foundationalist kind. With rare exceptions (for example, Richard Popkin), most interpreters have tried to eliminate the inconsistencies and contradictions in his writings and to pigeon-hole him victoriously. But Hume has given them a hard time indeed. The reason he has been such a poser is, in my opinion, that he—like postmodernists—does not offer any foundationalist perspective. In fact, their firm antifoundationalism makes allies ofhim and postmodernists. Anti-foundationalism For postmodernism, philosophy ceases to enjoy its traditional privilege of being a foundationalist discipline in either a metaphysical or an epistemological sense. Philosophy does not reveal any hidden depths, any deeper truths. It does not provide any unique insights guiding us beyond the immense diversity ofthe world towards its essential unity (metaphysics), nor does itprovide anyepistemological clue tothe world. Philosophy is denied the function of an epistemological police organizing the world into a well-arranged, easily-surveyed picture. For postmodernists, this modern "fantasy to seize reality"and makeitfully transparent and communicable is a source of terror.5 Postmodernism views the desire to master reality as leading to intellectual dictatorship, by eliminating the relevance and the rights ofthe other" which does not conform to modern principles and is thus downgraded in the modern hierarchy.

I shall situate Hume's scepticism within a broader philosophical and historical context. Firstly, I shall consider the place of Hume's thought within the early modern break with the almost millennium long metaphysical tradition, a break initiated by Descartes. The framework of being structured by a universal order was replaced by the individual human mind that broke free from any higher authority and became an autonomous cognitive agent. Subsequently, the ontological self-evidence of the world or the possibility of adequate knowledge came (...) under sceptical attack. Hume firmly belongs to this discourse and can be seen as the most consistent exponent of this early modern sceptical line. In this light, the ‘New Hume’ claim that Hume was an ontological realist will be shown to be misplaced in principle. Secondly, the strong influence of Pyrrhonism on Hume's philosophy will be considered, together with his concept of mitigated scepticism. The Pyrrhonian legacy is especially noticeable in Hume's acceptance of the weakness of reason and in his emphasis on the instructive role of philosophy – instead of attempting to make it the foundation of science it becomes a guide to a balanced, happy life. In this respect, Hume stands outside the early modern mainstream in philosophy. (shrink)

Complementary and alternative medicine is becoming increasingly popular in western countries, with estimates of CAM usage as high as 40%. This has prompted a change of attitude of the medical establishment: the initial dismissal of CAM is being replaced by a drive to integrate CAM into the mainstream. Two possible explanations for this integration thrust are considered. Firstly, integration could be motivated largely by cognitive interest in CAM. Secondly, integration could be mainly power-driven, aimed at controlling the alternative movement and (...) exploiting its capacity to make money. The second explanation seems more plausible, and is supported by data showing the paucity of research on CAM. The medical establishment does not sufficiently appreciate the challenge CAM poses, and does not consider its scientific appraisal to be a high priority. Instead, the allopathic community seems preoccupied with the opportunistic desire to protect its authority and social status. Such a discourse can become dogmatic, reluctant to revise critically the ‘accepted’ body of knowledge. Popper's critical rationalism could help to undercut dogmatism and encourage a critical, open-minded orientation of medical science. (shrink)

Abstract This paper aims to analyse Karl Popper's conception of ?three worlds?, and especially the problem of world 3?the world of objective knowledge. Firstly, I try to explain Popper's turn to ontological questions which I link to his antipsychologism and to issues raised by the development of logic after World War II. I then consider Popper's concept of the autonomy of world 3 and his attempt to introduce world 3 as a world of knowledge without a knowing subject. I conclude (...) that Popper did not succeed in unifying his central idea of autonomy of knowledge with the requirement of the creative role of the critical subject carrying out the evolution of knowledge. I see the core of this contradiction especially in his co?existing ideas of the timeless existence of world 3 and the elimination of the subject from it. The attempt to desubjectivize the realm of objective knowledge leads to a philosophically unbalanced standpoint which presupposes a creative subject and at the same time neglects it. Finally, I question Popper's account of the growth of world 3. Popper considers only cognitive motivations, and excludes a broad range of motivating factors which originate in the problems which we face in our lives, and affect our cognitive interests in world 3.
