Critical notice of Paul Feyerabend's Farewell to Reason. The basic difficulty with Feyerabend's argument is not that he goes too far in rejecting traditional philosophical views but that he does not go far enough. We should indeed dismiss philosophical attempts to forge a "direct line to heaven" and forswear introducing "caricatures" of the rationalist's conception of reason to accommodate the complexities of history. But we should also shun the temptation to regard tradition as a surrogate for reason and to elevate (...) freedom and democracy to the status of explanatory philosophical principles. It is no less a mistake to follow the relativist and fetishize cultural diversity than it is to follow the rationalist and fetishize reason. To recognise that we are on our own is not to repudiate rationalism in favour of relativism, but to bid farewell as firmly and as finally to both. (shrink)

The different “postmodern” philosophies that arose from the 1970s to the 1990s have often been considered as a kind of irrationalist-skeptical-relativist “ideology” or assorted amalgam, which in our time would dangerously take over the philosophical academy and western cultures, with grave risk for universalist or simply rationalist projects. Nevertheless, as the title of this article shows, a closer examination of some trends of postmodern thought would be able to perceive that they not only are uncomfortable with the label “relativist,” “irrationalist” (...) or “skeptical,” but also that they offer substantial arguments against, for example, the main theses of relativism. Naturally, none of these trends has any qualms about abominating universalism as well (the presumed mortal enemy of the relativists). Thus the most sensible conclusion would be that what really seems erroneous to authors such as those we shall approach here is the presumed dilemma (presented as inevitable) between relativism and universalism (it is curious that, at least as far as faith in the existence of such a dichotomy is concerned, these presumed irreconcilable enemies, which both the relativists and the universalists believe themselves to be, are plainly in agreement). Only if they subscribe to such a rejection of this dilemma could it be explained that important thinkers of the heterogeneous postmodern group (such as those whom I propose to have a dialogue with in this article) have scorned, on the one hand, any and all universal project of rationality, but have also strongly disallowed relativist proposals (just as, naturally, they have likewise taken advantage of the issue to deny their presumed adherence to relativism as such). This idea, however, has not been understood by a large part of the scholars involved today in epistemology and practical philosophy (the two philosophical specialties in which one most frequently faces the question of relativism). To approach this understanding, therefore, perhaps it would not be amiss to review the different arguments that some postmodern thinkers use against relativism. Specifically, we shall tale a look at the reasoning in this sense that has come from Gianni Vattimo (1936), Paul K. Feyerabend (1924-1994), and Richard Rorty (1931). All of them have too often had to suffer from the suspicion of being considered as relativists. To absolve philosophers such as these from such an accusation seems to be a sine qua non condition for understanding their true position towards the universalism versus relativism dilemma. (shrink)

The paper presents some thoughts about how an account of rationality might be recovered from what might have first appeared as anti-rationalistic ideas in the work of Kuhn and Feyerabend. The paper draws inspiration from some suggestions of Bernstein and Rorty, as well well as Brown's theory of rationality.

Relativism in the philosophy of science is widely associated with the work of Thomas Kuhn and Paul Feyerabend. Kuhn and Feyerabend espoused views about conceptual change and variation of scientific method that have apparent relativistic implications. Both held that scientific theories or paradigms may be incommensurable due to semantic variation. Two ways that truth may be relative because of semantic incommensurability will be distinguished. Davidson’s criticism of the idea of an untranslatable language will be discussed, as well as a (...) response to incommensurability based on the causal theory of reference of Kripke and Putnam. A form of relativism with respect to epistemic rationality may also be derived from the claims of Kuhn and Feyerabend about methodological variation. Kuhn’s initial suggestions about paradigm-dependent standards and absence of extra-paradigmatic standards give rise to a view on which rationality is relative to paradigm. Kuhn’s later view that there is a stable set of shared scientific values is less prone to relativistic interpretation. Feyerabend’s claim that “anything goes” suggests an extreme form of relativism, but should be understood instead as the view that all rules of method may be violated in some circumstances. The latter brings Feyerabend’s view into line with Kuhn’s later view. (shrink)

The chapter deals with the two most distinctive elements of the Introduction of the Naturrecht Feyerabend, namely the notions of an end in itself and autonomy. I shall argue that both are to be interpreted with regard to the aim of explaining the ground of right. In this light, I suggest that the notion of an end in itself counters a voluntarist conception like Achenwall’s with a claim whose necessity has a twofold ground: First, the representation of an unconditional worth (...) emerges as a structural element of the practical use of reason. Second, that representation concerns the necessary self-understanding of moral subjects. Finally, I argue that the other distinctive element, the occurrence of the notion of autonomy, is best understood as an application of that idea to a specific issue, which Kant addresses by showing that freedom is a self-regulating domain.

My aim in this chapter is to clarify the nature of the shift in Feyerabend’s philosophical thinking in the 1970s, focusing on issues of realism, relativism, and pluralism. Contra-Preston, I argue that realism-relativism is a misleading variable for characterizing Feyerabend’s shift in the 1970s. Rather, I characterize this shift as Feyerabend’s expansion of pluralism and suggest that this shift appears in Feyerabend’s publications starting in the late-1960s (e.g., Feyerabend 1968b, 1969b, 1970a, 1970c). Adopting the terminology of Brown and (...) Kidd (2016), this shift is characterized by a move from arguments for pluralism within science to broader arguments for pluralism in society. I argue that this shift was largely due to: (1) Feyerabend’s rejection of an empiricist demarcation criterion for science in the mid-1960s, and (2) Feyerabend’s incorporation of Mill’s arguments for pluralism into his own publications starting in 1970. This shift can be characterized as a broadening or expanding the scope of Feyerabend’s arguments for pluralism from contexts of scientific knowledge to the broader context of social or cultural (including ethical) knowledge. I articulate this argument with reference to the framework for classifying Feyerabend’s works formulated by Brown and Kidd (2016). Against Brown and Kidd (and Preston), I argue that realism-relativism is a red-herring as a variable for distinguishing Feyerabend’s early and middle works. Brown and Kidd’s distinction between pluralism within science and pluralism in society is a more useful variable for characterizing Feyerabend’s shift in thinking in the 1970s. Whereas Preston (1997) and Brown and Kidd (2016) identify the beginning of Feyerabend’s pluralism in society phase in 1978 with the publication of Science in a Free Society (Feyerabend 1978), I suggest that the relevant shift occurs much earlier, and it appears in Feyerabend’s publications starting in 1970 (Feyerabend 1970a, 1970b). On this understanding, Feyerabend’s philosophical shift (c. 1970) should be viewed as an expansion (or broadening) of the scope of application of his pluralist arguments, inspired by Mill’s ethical arguments for pluralism in society (Mill 1859/1977).

This paper explores the relationship between scepticism and epistemic relativism in the context of recent history and philosophy of science. More specifically, it seeks to show that significant treatments of epistemic relativism by influential figures in the history and philosophy of science draw upon the Pyrrhonian problem of the criterion. The paper begins with a presentation of the problem of the criterion as it occurs in the work of Sextus Empiricus. It is then shown that significant treatments of (...) epistemic relativism in recent history and philosophy of science (critical rationalism, historical philosophy of science and the strong programme) draw upon the problem of the criterion. It is briefly suggested that a particularist response to the problem of the criterion may be put to good use against epistemic relativism. (shrink)

I confront Feyerabend's position and critical rationalism in order to have a foundation or starting point for my (historical) investigation. The main difference of his position towards falsificationism is the belief that different theories cannot be discussed rationally. Feyerabend is convinced that Galilei's observations with the telescope in the historical context of the Copernican revolution supports his criticism. In particular, he argues that the Copernican theory was supported by deficient hypotheses, and falsifications were disposed by ad hoc hypotheses and propaganda. (...) Furthermore, he claims that his philosophy of science reconstructs Galilei's defence of the Copernican theory. He introduces a central principle of his position (the principle of tenacity) in order to justify a research strategy of not eliminating falsified theories. He tries to show that the tenacious defence of a theory corresponds to Galilei's defence of the Copernican theory. Remarkably, Feyerabend's approach to explain the development of science earns an important support from his interpretation of Galilei's observations. On this basis I give a falsificationist interpretation of Galilei's observations with the telescope, and oppose this interpretation to Feyerabend's. From a falsificationist perspective, auxiliary hypotheses compete during the Copernican revolution which can (with some effort) be critically discussed. Then I analyse the historical case in order to test Feyerabend's interpretation of the Copernican revolution. Inter alias I investigate thoroughly whether Galilei, as Feyerabend claims, immunised falsifications of the Copernican theory by the introduction of ad hoc hypotheses. The investigation considers Galilei's explanation of Venus' phases, his establishment of the irradiation hypothesis, the explanation of the telescope's functionality, and the role of the reproducibility of the observations with the telescope. Finally I provide a rational reconstruction of Galilei's falsification of the Ptolemaic theory. The formalisation shows that Galilei was not a cautious critical rationalist, but a very confident scientist using the method of falsification. (shrink)

Review of the third edition of Paul Feyerabend's Against Method.

Chapter 2 primarily discusses Bernstein’s account and its differences both from Nagle’s metaphysical realism and Rorty’s postmodern pragmatism. Trying to diagnose assumptions that polarize thinkers to become objectivists and relativists, Bernstein articulates a Cartesian Anxiety he thinks they ironically both share. Descartes’ anti-skeptical wave of rigor was presented as a rationalistic project of rebuilding an unstable and dilapidated ‘house of knowledge’ on secure philosophical and scientific foundations. His overtly foundationalist metaphor of rebuilding from timbers set “in rock or hard clay” (...) shapes Descartes’ attempt to refute the skeptic and to secure the objectivity of knowledge as pursued by a more rigorous and analytical method of knowing.

Ethical objectivists hold that there is one and only one correct system of moral beliefs. From such a standpoint it follows that conflicting basic moral principles cannot both be true and that the only moral principles which are binding on rational human agents are those described by the single true morality. However sincerely they may be held, all other moral principles are incorrect. Objectivism is an influential tradition, covering most of the rationalist and naturalist standpoints which have dominated nineteenth and (...) twentieth century moral philosophy: there is widespread agreement amongst relativists themselves that objectivism is firmly rooted in common sense.

This article explains that and how Robert S. Hartman and Brand Blanshard, two of the most insightful philosophers of the 20th Century, were complete rationalists in their approach to philosophical problems, especially those in value theory. They both rejected emotive, subjectivist, and relativistic approaches to ethical values. Both were convinced that “intrinsic goodness” is the most important, meaningful, and basic of all ethical or moral concepts. Just how they understood reasonableness and the task of philosophers is explored. Significant differences between (...) the two on the meaning of “good” are examined. Blanshard’s equating of “intrinsically good” with “fulfillment and pleasure” is critiqued, and Hartman’s alternative to this is presented and defended. (shrink)

Traditional epistemology is haunted by the spectre of scepticism. Yet the more pressing concern in the contemporary intellectual scene must surely be relativism rather than scepticism. This has been the case in the history and philosophy of science since the work of Thomas Kuhn and Paul Feyerabend, to say nothing of the emergence of the sociology of scientific knowledge. In Epistemic Relativism: A Constructive Critique, Markus Seidel comes firmly to grips with this modern spectre. Though Seidel devotes attention (...) to other forms of relativism, the primary focus of the book is epistemic relativism, which he understands to be relativism about epistemic justification. Relativist or relativist-tending authors such as Kuhn, Nelson Goodman, Martin Kusch, Richard Rorty and Peter Winch receive some discussion . But Seidel takes as his main relativist target the work of the founding figures of the Edinburgh “strong programme”, Barry Barnes and David Bloor. While .. (shrink)

The article analyzes Petro Kudriavtsev’s historical philosophical conception in the context of basic tendencies and reference points of development of historical philosophical science in Europe in 19th – the beginning of 20th cent. For this purpose, the place and significance of reception of European philosophy in the P. Kudriavtsev’s historic philosophical works are identified. Furthermore, the article discusses the complex of philosophical and historical ideas that appeared to be productive for development of Kudriavtsev’s original historical philosophical conception. The latter is (...) proved to be formulated in the process of deep creative interpretation of European historical philosophical studies achievements, such as ethics and philosophical constructions of the European thought. The author finds out the particularity of the P. Kudriavtsev’s original approach to understanding of historical philosophical process, based on comprehension of rationalism and empiricism, two opposite models of historical philosophical knowledge. Besides, the author argues for the similarity in approach to the history of philosophy between P. Kudriavtsev and the representatives of historical-philosophical tradition after Hegel. Reconstruction of P. Kudriavtsev’s historical philosophical conception allows the author to conclude, on the one hand, that conception reflected one of the central problems in Western European philosophy on the edge of 19 th – 20 th centuries – the problem of values. On the other hand, the conception was aimed to oppose the relativistic and nihilistic tendencies, which dominated in Modern European philosophy. (shrink)

ENGLISH: The author investigates whether the model prevalent today of an “humble reason” - based on fallibilism and epistemic humility - is the most appropriate to express the theological truth, even in the light of the debate within the contemporary theism (rational theology). To answer this question it is necessary to examine the epistemological status of “human truth” and the “truth of faith”, in order to develop a common approach to sciences, philosophy and theology. Finally, the author shows how the (...) communitarian dimension and the “choice” (a call for freedom) are inherent to theology understood as “critical faith”, whose peculiarity is to posit itself without nostalgia in the middle between fideism, rationalism and a certain relativism. From the path, finally, it emerges the proposal of a new “cristeologia”. ITALIAN: Il rapporto tra fede e ragione è la questione meta-teologica per eccellenza. L’autore si propone dunque d’indagare se il modello oggi prevalente di “ragione umile” – basato su fallibilismo e umiltà epistemica – sia il più adeguato per esprimere le verità teologiche, anche alla luce del dibattito interno al teismo contemporaneo (teologia razionale). Per rispondere a questa domanda è necessario esaminare lo statuto epistemologico della verità umana e della verità di fede, per poter elaborare un metodo comune alle discipline scientifiche, filosofiche e teologiche, capace di trovare un equilibrio tra fideismo e positivismo teologico. Dopo una breve panoramica storica dei rapporti tra fede e ragione nel pensiero occidentale (con particolare attenzione alla dottrina dei praeambula fidei), l’articolo cercherà di mostrare come, nel paradigma della verità relazionale e del fallibilismo sia necessario integrare il problema delle fonti, dell’autorità, del concetto di ispirazione e della nozione di “rivelazione”, giacché contraddistinguono la teologia rispetto alla filosofia. Si mostrerà infine come la dimensione comunitaria e della scelta (appello alla libertà) siano connaturate alla teologia intesa come fede critica, la cui peculiarità è di collocarsi senza nostalgie nel mezzo tra fideismo, razionalismo e un certo relativismo. Dal percorso emergerà infine la proposta di una nuova "cristeologia". (shrink)

The 18th century witnessed the transformation of aesthetics into an independent philosophical discipline. In this period, two main traditions emerged, based on which we can categorize aesthetic theorists. The first of these is classical or rationalist aesthetics, and the other is empiricist or subjective aesthetics. Because classical/rational aesthetic theories were largely based on Cartesian metaphysics, they also inherited the difficulties faced by Cartesian metaphysics. For Descartes, senseperception is not a reliable mode of cognition and truth only comes out of the (...) ideas of pure understanding. Where Descartes' philosophy came to a dead end was that it could not convincingly explain how the concepts in our minds represent reality that is independent of us. This problem also manifested itself in the rationalist aesthetics. Similarly, the empiricist theory inherited the weaknesses of the empiricist epistemology. The main problem of empiricism was to overcome subjectivism and reach universal principles that make sense of the world surrounding us. To overcome the relativism of the empiricist epistemology, empiricist theoreticians claimed that there is an intuition, a common feeling shared by all human beings. However, this common feeling could not be proven empirically. Diderot created a new aesthetic theory that aimed to reconcile rationalist and empiricist aesthetics by redefining the term perception. This article discusses Diderot's innovative effort to create a new aesthetics free from the limits of rationalism and empiricism. (shrink)

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.

This paper examines Friedrich Nietzsche’s critique of traditional philosophy and his radical alternative: perspectivism. Nietzsche challenges the philosophical pursuit of absolute truth, arguing that what thinkers present as objective discovery is, in fact, shaped by personal biases, cultural assumptions, and the will to power. He critiques Platonism, rationalism, and Kantian metaphysics, exposing them as constructed systems rather than neutral inquiries into reality. In contrast, Nietzsche’s perspectivism rejects the idea of an objective, neutral standpoint. He argues that knowledge is always interpretative, (...) shaped by human needs and conditions. However, this does not lead to relativism; Nietzsche insists that some perspectives are more coherent, and more life-affirming than others. His aphoristic writing style reflects this, engaging the reader in an active process of interpretation. The paper further explores the implications of perspectivism, particularly its influence on Michel Foucault, Thomas Kuhn, and Richard Rorty, whose work in epistemology, science, and pragmatism builds upon Nietzsche’s rejection of absolute truth. Finally, it addresses key challenges to perspectivism, including accusations of epistemic nihilism, the validity of science, and the self-referential critique. The analysis argues that Nietzsche’s framework does not deny meaning but reorients how we assess knowledge, shifting the focus from objectivity to coherence, strength, and life-affirmation. (shrink)

Karl Popper, ca raționalist critic, a fost un oponent al tuturor formelor de scepticism, convenționalism și relativism în știință. În 1935 a scris Logica cercetării (Logik der Forschung. Zur Erkenntnistheorie der modernen Naturwissenschaft), traducând ulterior cartea în engleză și publicând-o sub titlul The Logic of Scientific Discovery (1959) considerată ca o lucrare de pionierat în domeniu. Multe dintre argumentele din această carte sunt îndreptate împotriva membrilor "Cercului Vienez", precum Moritz Schlick, Otto Neurath, Rudolph Carnap, Hans Reichenbach, Carl Hempel și (...) Herbert Feigl. 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. Popper a contribuit semnificativ la dezbaterile privind metodologia științifică generală, demarcarea științei de pseudoștiință, natura probabilității și metodologia științelor sociale. (shrink)

The paper explores the relativistic implications of the thesis of incommensurability. A semantic form of incommensurability due to semantic variation between theories is distinguished from a methodological form due to variation in methodological standards between theories. Two responses to the thesis of semantic incommensurability are dealt with: the first challenges the idea of untranslatability to which semantic incommensurability gives rise; the second holds that relations of referential continuity eliminate semantic incommensurability. It is then argued that methodological incommensurability poses little risk (...) to the rationality or objectivity of science. For rational theory choice need neither be dictated by an algorithm nor governed by a binding set of rules. The upshot of the discussion is deflationary. There is little prospect for a relativistic conception of science based on inflated claims about the incommensurability of scientific theories. (shrink)

What can be understood of other cultures? And what can we learn about people in general from the study of other cultures? In the three closely related essays that constitute this book and which have already created considerable controversy in their original French versions, and been rewritten and expanded for this edition, Dan Sperber discusses these fundamental issues of anthropology. In the first essay he analyses the way in which anthropology is written and read. In the second, he offers a (...) novel rationalist alternative to cultural relativism, based on both anthropological and psychological arguments, and illustrated by his own fieldwork in Ethiopia. The third essay provides an assessment of the work of Lévi-Strauss, in which the arguments of the previous two essays are linked with an incisive critique of Lévi-Strauss' contribution to the study of cultural variation.

These essays reveal another side of Horkheimer, focusing on his remarkable contributions to critical theory in the 1930s. Max Horkheimer is well known as the director of the Frankfurt Institute for Social Research and as a sometime collaborator with Theodor Adorno, especially on their classic Dialectic of Enlightenment. These essays reveal another side of Horkheimer, focusing on his remarkable contributions to critical theory in the 1930s. Included are Horkheimer's inaugural address as director of the Institute, in which he outlines the (...) interdisciplinary research program that would dominate the initial phase of the Frankfurt School, his first full monograph, and a number of other pieces published in the 1930s. The essays, most of which have not appeared in English before, are surprisingly relevant to current post-philosophy debates, notably "On the Problem of Truth," with its focus on pragmatism, and "The Rationalism Debate in Current Philosophy," a sustained critique of the post-Cartesian philosophy of consciousness. Horkheimer's 1933 critique of Kantian ethics, "Materialism and Morality," is of particular interest given the current reaction to the neo-Kantian aspect of Habermas's work. There are also essays relevant to the current foundations debate within Continental philosophy, and the rationality/relativism question is sustained throughout the volume. (shrink)

Philosophy of science and history of science both have a significant relation to science itself; but what is their relation to each other? That question has been a focal point of philosophical and historical work throughout the second half of this century. An analysis and review of the progress made in dealing with this question, and especially that made in philosophy, is the focus of this thesis. Chapter one concerns logical positivist and empiricist approaches to philosophy of science, and the (...) significance of the criticisms levelled at them by analytic epistemologists such as Willard Quine and 'historicist' philosophers, especially Thomas Kuhn. Chapter two details the attempts by Kuhn and Lakatos to integrate these historicist criticisms with historically oriented philosophy of science, in their separate attempts at providing rational explanations of historical developments. Kuhn's latest work seeks to mend fences with philosophy, but his efforts remain too closely tied to the epistemological approaches strongly criticized in his earlier work. Lakatos' treatment of history is much more subtle than most have understood it to be, but the conception of scientific rationality that arises out of it is transformed into an abstract cultural product, more reminiscent of Hegel's geist than of individual human rationality. Chapters three and four discuss the recommendations of Lakatos and Laudan to historians with regard to historiography, and the actual historiographies and philosophy of history of practicing historians and historians of science. The philosophers' contributions indicate little concern for the historians' own methods, materials, and purposes; and the historians' writings present methodologies for history of science that are independent of the normative demarcations of philosophy of science, pace Lakatos and Laudan. Chapter five develops a philosophical position that fosters a more productive engagement between philosophy and history of science, a 'methodological historicism' that embraces the possibility of an important role for social and political factors in a philosophical study of scientific development. The epistemological relativism that might accompany such a historicist position need not be the radical epistemological anarchism of Feyerabend, though it will allow for a significant underdetermination of scientific development by reason nonetheless.

The coronavirus pandemic, like its predecessors - AIDS, Ebola, etc., is evidence of the evolutionary instability of the socio-cultural and ecological niche created by mankind, as the main factor in the evolutionary success of our biological species and the civilization created by it. At least, this applies to the modern global civilization, which is called technogenic or technological, although it exists in several varieties. As we hope to show, the current crisis has less ontological as well as epistemological roots; its (...) reason lies in the main evolutionary trends in the development of science as a social institution. It was only later that epistemological factors were transformed into existential-ontological factors associated with the asymmetry of the existence of civilization and our biosocial nature. The perception or ignorance of a risk factor as a real fact is determined by the presence or absence of knowledge about it. In other words, risk is the result of the integration of the corresponding ontological concept into the general categorical structure. The plurality of such structures is a hallmark of multidisciplinary ontologies, each of which is associated with its own factual continuum. The aim of this study was to conceptually model for support relativistic parameter of evolutionary efficiency of stable evolutionary human strategy (SESH) in its techno-rationalistic module. The meaning of this term is equivalent to the category of scientific and technological development. (shrink)

Abstract: This study explores some theoretical issues in scientific research such as, the nature of experimentation and problems of methodology in scientific practice as well as the question of truth, rationality, objectivity and utility of scientific discoveries. The paper discusses a number of theorizing that have emerged in response to the challenge raised by the above concerns. Epistemological models of science from critical rationalists, like Popper, Kuhn, Feyerabend and the neo-pragmatic methodological orientation of Arthur Fine’s Natural Ontological Attitude (NOA) to (...) Science, have been adopted as points of discussion on what science as an empirical discipline entail. The paper concludes that a rigorous epistemological discussion on the methodology of scientific inquiry is a desideratum for the progress of science. (shrink)

Adviser: Professor Stefan Baumrin In the first chapter I introduce the distinction between metaethics and normative ethics and argue that metaethics, properly conceived, is a part of cognitive science. For example, the debate between rationalism and sentimentalism can be informed by recent empirical work in psychology and the neurosciences. In the second chapter I argue that the traditional view that one’s theory of semantics determines what one’s theory of justification must be is mistaken. Though it has been the case that (...) there are ‘typical’ combinations of semantic and justificational theories this is by no means forced on one. In the third chapter I examine two current kinds of expressivism; that of Blackburn and Copp. Each gives us an example of different combinations of semantic and justificatory theory. In Blackburn’s case he combines a use theory of meaning with a classic emotivist theory of justification, In Copp’s case it is a neo-Gricean philosophy of language with a realist’s theory of justification. I find both of these wanting as they ultimately collapse into relativistic subjectivism. In the fourth and fifth chapter I turn to developing Emotive Realism. The basic idea behind this view is that when someone says ‘x is wrong/right’ that person has (a) expressed a moral emotion about x and at the same time (b) expressed the belief that the emotion in (a) is the correct one to have. The belief expressed in (b) will be true or false depending on one’s theory of justification. In the fourth chapter I argue that we need separate semantic theories for thoughts and sentences. In the fifth chapter I fill in the details of Emotive Realism as I see it. (shrink)

Despite the centrality of the idea of history to Dewey's overall philosophical outlook, his brief treatment of philosophical issues in history has never attracted much attention, partly because of the dearth of the available material. Nonetheless, as argued in this essay, what we do have provides for the outlines of a comprehensive pragmatist view of history distinguished by an emphasis on methodological pluralism and a principled opposition to thinking of historical knowledge in correspondence terms. The key conceptions of Dewey's philosophy (...) of history outlined in this paper -- i.e. historical constitution of human nature, constructivist ontology of historical events, as well as the belief that the proper form of historical judgments is underwritten by the category of continual change -- are discussed with a view to the current challenges in philosophy of history, e.g. the contest between naturalism and rationalism, objectivity and relativism, questions surrounding the function of narrative in history, and the relationship of history to the problems of identity and self-knowledge. The intended upshot of the essay is to suggest that Dewey's brief yet substantial analysis may be capable of supplying the guiding principles for articulating a viable and promising pragmatist (and naturalist) conception of historical knowledge.

TWENTIETH-CENTURY ETHICS. AFTER NIETZSCHE -/- Preface This book tells the story of twentieth-century ethics or, in more detail, it reconstructs the history of a discussion on the foundations of ethics which had a start with Nietzsche and Sidgwick, the leading proponents of late-nineteenth-century moral scepticism. During the first half of the century, the prevailing trends tended to exclude the possibility of normative ethics. On the Continent, the trend was to transform ethics into a philosophy of existence whose self-appointed task was (...) that of describing the human condition as consisting of choices, as unavoidable as arbitrary, without any attempt at providing criteria for making such choices. In the Anglo-Saxon countries, the heir of ethics was a philosophy of morality, that is, an analysis of the language of morality that intended to clarify valuations without trying to justify them. 1958 was the year of the normative turn that led to the Rehabilitation of practical philosophy, a turn followed by decades of controversies between distinct kinds of normative ethics: utilitarian, Kantian, virtue ethics. While the controversy was raging, a quiet revolution took place, that of applied ethics which surprisingly dissolved the controversy's very subject matter by providing methods for making convergence possible on intermediate principles even when no agreement was available about first principles. The normative turn and the revolution of applied ethics have led us, at the turn of the century, to a goal that was quite far from the starting point. Instead of scepticism and relativism that was the fashion at the beginning of the century, at the beginning of the third millennium impartial and universal moral arguments seem to hold the spot being supported, if not by a final rational foundation, at least by reasonableness, the most precious legacy of the Enlightenment. -/- ● TABLE OF CONTENTS -/- ● I Anglo-Saxon philosophy: naturalism 1.

It stresses the role of religious concerns, as well as that of the Idealist legacy. It argues that PE is more a patchwork of somewhat diverging contributions than a unitary work, not to say the paradigm of a new school in Ethics. -/- ●III Anglo-Saxon philosophy: non-cognitivism 1.

Stevenson and the pragmatics of moral language 6. Stevenson and the methods for solving ethical disagreement 7. Hare and prescriptivism The chapter reconstructs first the discussion after Moore. The naturalistic-fallacy argument was widely accepted but twisted to prove instead that the intuitive character of the definition of 'good', its non-cognitive meaning, in a first phase identified with 'emotive' meaning. Alfred Julius Ayer is indicated as a typical proponent of such non-cognitivist meta-ethics. More detailed discussion is dedicated to Bertrand Russell's ethics, a more nuanced and sophisticated doctrine, arguing that non-cognitivism does not condemn morality to arbitrariness and that the project of rational normative ethics is still possible, heading finally to the justification of a kind of non-hedonist utilitarianism. Stevenson's theory, another moderate version of emotivism is discussed at some length, showing how the author comes close to the discovery of the role of a pragmatic dimension of language as a basis for ethical argument. A section reconstructs the discussion from the Forties about Hume's law, mentioning Karl Popper's argument and Richard Hare's early non-cognitivist but non-emotivist doctrine named prescriptivism. -/- ●IV Anglo-Saxon philosophy: critics of non-cognitivism 1.

Plessner, Gehlen and the Philosophische Anthropologie -/- The chapter illustrates first the idea of phenomenology and the Husserl's project of a phenomenological ethic as illustrated in his 1908-1914 lectures. The key idea is dismissing psychology and trying to ground a new science of the apriori of action, within which a more restricted field of inquiry will be the science of right actions. Then the chapter illustrates the criticism of modern moral philosophy conducted in the 1920 lectures, where the main target is naturalism, understood in the Kantian meaning of primacy of common sense. The third point illustrate is Adolph Reinach's theory of social acts as a key the grounding of norms, a view that sketches the ideas 'discovered' later by Clarence I. Lewis, John Searle, Karl-Otto Apel and Jürgen Habermas. A final section discusses Nicolai Hartman, who always refused to define himself a phenomenologist and yet developed a more articulated and detailed theory of 'values' – with surprising affinities with George E. Moore - than philosophers such as Max Scheler, who claimed to be Husserl's legitimate heirs. -/- ● VI Continental philosophy: the critics of the philosophy of values 1.

Brandt and indirect conscience utilitarianism -/- The chapter addresses the issue of the complex process of self-transformation Utilitarianism underwent after Sidgwick's and Moore's fatal criticism and the unexpected Phoenix-like process of rebirth of a doctrine refuted. Two examples give the reader a glimpse at this uproarious process. The first is Roy Harrod Wittgensteinian transformation of utilitarianism in pure normative ethics depurated from hedonism as well as from whatsoever theory of the good. This transformation results in preference utilitarianism combined with a 'Kantian' version of rule utilitarianism. The second is Richard Hare's two-level preference utilitarianism, where act utilitarianism plays the function of the eventual rational justification of moral judgments and rule-utilitarianism that of an action-guiding practical device. -/- ● IX Normative ethics: neo-Aristotelianism and virtue ethics 1. Hannah Arendt, action and judgement 2. Hans-Georg Gadamer and phronesis 3. Alasdair MacIntyre on practices, virtues, and traditions 5. Stuart Hampshire on deliberation 6. Bernard Williams and moral complexity 7. Feminist ethics -/- Sect 1 reconstructs the post-war rediscovery of ethics by many German thinkers and its culmination in the Sixties in the movement named 'Rehabilitation of practical philosophy' is described. Heidegger's most brilliant disciples were the promoters of this Rehabilitation. Hans-Georg Gadamer is a paradigmatic example. His reading of Aristotle's lesson I reconstructed, starting with Heidegger's lesson but then subtly subverting its outcome thanks to the recovery of the significant role of the notion of phronesis. Sect 3 discusses the three theses defended by Anscombe in 'Modern Moral Philosophy'. It argues that: a) her answer to the question "why should I be moral?" requires a solution of the problem of theodicy, and ignores any attempts to save the moral point of view without recourse to divine retribution; b) her notion of divine law is an odd one more neo-Augustinian than Biblical or Scholastic; c) her image of Kantian ethics and intuitionism is the impoverished image manufactured by consequentialist opponents for polemical purposes and that she seems strangely accept it; d) the difficulty of identifying the "relevant descriptions" of acts is not an argument in favour of an ethics of virtue and against consequentialism or Kantian ethics, and indeed the role of judgment in the latter is a response to the difficulties raised by the case of judgment concerning future action. The chapter gives a short look at further developments in the neo-naturalist current trough a reconstruction of Philippa Foot's and Peter Geach's critiques to the naturalist-fallacy argument and Alasdair MacIntyre's grand reconstruction of the origins and allegedly inevitable failure of the Enlightenment project of an autonomous ethic. -/- ● X Normative ethics: Kantian and rights-based ethics 1.

Donagan and persons as ends in themselves Parallel to the neo-Aristotelian trend, there was in the Rehabilitation of practical philosophy a Kantian current. This current started with the discovery of the pragmatic dimension of language carried out by Charles Peirce and the Oxford linguistic philosophy. On this basis, Karl-Otto Apel singled out as the decisive proponent of the linguistic and Kantian turn in German-speaking ethics, worked out the performative-contradiction argument while claiming that this was able to provide a new rational and universal basis for normative ethics. The chapter offers an examination of his argument in some detail, followed by a more cursory reconstruction of Jürgen Habermas's elaboration on Apel's theory. -/- ● XI The applied ethics renaissance 1.

The chapter argues that Rawls's distinction between a "political" and a "metaphysical" approach to the theory of justice, one central part of ethical theory, is a formulation of the same basic idea at the root of both the principles approach and the new casuistry, both discussed in the following chapter. The idea is that it is possible to reach an agreement concerning positive moral judgments even though the discussion is still open – and in Rawls' view never will be close – on the essential criteria for judgment. -/- ● XII Fin-de-siècle metaethics 1.

In this article I take a critical look at the origins and sources of Bruno Latour's pluralism as it is expressed in his book AN INQUIRY INTO MODES OF EXISTENCE, and compare it to other similar projects (Wittgenstein, Feyerabend, Badiou). I consider the accusations of reductionism and of relativism, and demonstrate that Latour's «empirical metaphysics» is not an ontological reductionism but a pluralist ontology recognising the existence of a plurality of entities and of types of entities. Nor is it (...) an epistemological relativism but an ontological pluralism affirming the existence of a plurality of types of existence. These two strands, pluralist ontology and ontological pluralism, mutually reinforce each other to produce at least the outlines of a robust pluralist realism. (shrink)

The discovery of the role of models in science by Granger parallels the analogous discovery made by Mary Hesse and Marx Wartofsky. The role models are granted highlights the linguistic dimension of science, resulting in a 'softening' of Bachelard's rationalistic epistemology without lapsing into relativism. A 'linguistic' theory of metaphor, as contrasted with Bachelard's 'psychological' theory, is basic to Granger's account of models. A final paragraph discusses to what extent Granger's 'mature' theory of models would imply a revision of (...) his early economic methodology. (shrink)

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)

In this paper, I examine the problem of Bayle's skepticism. I show that he is not a wholesale skeptic. Rather, he thinks that reason is plagued by internal conflicts. But its principles, which clash with each other, can be adopted separately from each other. It is often what we have to do when dealing with metaphysical problems. This also entails that reason is not to be rejected as a whole when it happens to be contradicted by faith; only some of (...) its principles have to be denied, and solely in that case. Further, Bayle believes that we possess absolute certainly in our knowledge of ethical principles. I show how this is compatible with his relativism in other domains by putting back his contention in the context of Reformed thought. (shrink)

The paper deals with a charge that is often made against consequentialist moral theories: that they are unacceptably demanding. This is called the Overdemandingness Objection. The paper first distinguishes three interpretations of the Objection as based on the three dimensions of moral demands: scope, content, and authority. It is then argued that neither the scope, nor the content-based understanding of the Objection is viable. Constraining the scope of consequentialism is neither helpful, nor justified, hence the pervasiveness of consequentialism cannot be (...) the ground for the Objection. Although recent approaches interpret the Objection as a claim about the excessively demanding content of consequentialism, it is argued that the stringency of consequentialism is also unproblematic insofar as demandingness is concerned. These results show that the only way to put the Objection is by focusing on the inescapability of consequentialism. The Objection thus takes the following form: consequentialism is overdemanding because it requires us, with decisive force, to do things that we do not have decisive reason to perform. However, in the last part of the paper it is shown that defending this interpretation of the Objection is at best an open-ended and perilous enterprise. The paper concludes that the case for authority is weak: although this is the only defensible way to advocate the Objection, its successful defence depends on the truth of further substantial philosophical positions.

Paul Feyerabend argued that theories can be faced with experimental anomalies whose refuting character can only be recognized by developing alternatives to the theory. The alternate theory must explain the experimental results without contrivance and it must also be supported by independent evidence. I show that the situation described by Feyerabend arises again and again in experiments or observations that test the postulates in the standard cosmological model relating to dark matter. The alternate theory is Milgrom’s modified dynamics. I discuss (...) three examples: the failure to detect dark-matter particles in laboratory experiments; the lack of evidence for dark-matter sub-haloes and the dwarf galaxies that are postulated to inhabit them; and the failure to confirm the predicted orbital decay of Milky Way satellite galaxies and other systems due to dynamical friction against the dark matter. In each case, Feyerabend’s criterion directs us to interpret the experimental or observational results as an indirect refutation of the standard cosmological model in favor of Milgrom’s theory.

This essay introduces the transcription and translation of Paul Feyerabend's "Der Begriff der Verständlichkeit in der modernen Physik" [The concept of intelligibility in modern physics] (1948), which is an early essay written by Paul Feyerabend in 1948 on the topic of intelligibility (Verständlichkeit) and visualizability (Anschaulichkeit) of physical theories. The existence of such essay was likely. It is listed in his bibliography as his first publication. Yet the content of the essay was unknown, as no original or copy is extant (...) in Feyerabend's Nachlass and no known published version was available to the community—until now. The essay has both historical and philosophical interest: it is, as far as our current knowledge goes, Feyerabend's earliest extant publication. It documents Feyerabend's philosophical interest as a physicist-to-be, in what he himself called his “positivist” phase; and it gives a rare if fragmentary insight into the early discussions of the ‘Third Vienna Circle’ and, more generally, the philosophical culture of discussion in Vienna.

Paul Feyerabend, one of the most original and nonconformist epistemologists of the 20th century, is known for describing science as an essentially anarchic enterprise characterized by different, sometimes contradictory, methods, approaches and ways of reasoning. But it was through his reflections on art and myth that he developed an even more radical view: there are different forms of human thought, each characterized by a different rationality and reality, and science is only one of them. And in intellectual history there is (...) only change, but not progress. (shrink)

I suggest following Paul Feyerabend's own advice, and interpreting Feyerabend's work in light of the principles laid out by John Stuart Mill. A review of Mill's essay, On Liberty, emphasizes the importance Mill placed on open and critical discussion for the vitality and progress of various aspects of human life, including the pursuit of scientific knowledge. Many of Feyerabend's more unusual stances, I suggest, are best interpreted as attempts to play certain roles--especially the role of "defender of unpopular minority opinion"--that (...) are necessary to fulfilling Mill's conditions for rational exchange and optimal human development.

The thesis of this article is that Feyerabend’s philosophy of science, hinged on his pillar of ‘anarchism’ and ‘anything goes’ can serve as a challenge for scientific and technological development in Africa. Africa has been largely tagged as ‘underdeveloped’ because she has failed to chart her own course of scientific development, and has somewhat felt satisfied playing the dependent role. This work agrees with Feyerabend’s thesis that knowledge (scientific) is a local commodity designed to solve local problems. Using the textual (...) and contextual methods we contend that every culture, certainly including Africa, can harness her own indigenous scientific categories and develop from her own local perspective. We reason with Feyerabend that Western science is not sacrosanct, nor its method of rationality the only path toward development. The work reveals that Feyerabend’s views, though challenging and somewhat intriguing, are very congenial to our African experience. Thus we conclude by adumbrating some positive implications that his views have for the Africans, especially towards scientific and even technological development. (shrink)

I argue that we can profitably understanding Feyerabend’s work in at least the latter half of his career in terms of a series of experiments with ways of conceptualising and criticising scientism, under the aegis of a ‘critique of scientific reason’. The critique of science’s self-understanding was the more sophisticated and successful, while the critique of scientific modernity was more erratic and less effective, due mainly to the failure to take up the necessary resources.

Relativists make room for the possibility of “faultless disagreement” by positing the existence of subjective propositions, i.e. propositions true from some points of view and not others. We discuss whether the adoption of this position with respect to a certain domain of discourse is compatible with a realist attitude towards the matters arising in that domain. At first glance, the combination of relativism and realism leads to an unattractive metaphysical picture on which reality comprises incoherent facts. We will sketch (...) the contours of a realist-relativist position called “subjectivism”, which avoids this result by giving up the assumption that the points of view of different subjects are all metaphysically “on a par”.

Feyerabend is well-known as a pluralist, and notorious for his defences of, and sympathetic references to, heterodox subjects, such as parapsychology. Focusing on the latter, I ask how we should understand the relationship between the pluralism and the defences, drawing on Marcello Truzzi's and Martin Gardner's remarks on Feyerabend along the way.

I offer a new interpretation of Feyerabend’s ‘conquest of abundance’ narrative. I consider and reject both the ontological reading as implausible and the ‘historical’ reading as uncompelling My own proposal is that the ‘conquest of abundance’ be understood in terms of an impoverishment of the richness of human experience. For Feyerabend, such abundance is ‘conquered’ when individuals internalize distorting epistemic prejudices including those integral to the theoretical conceptions associated with the sciences. I describe several ways, identified by Feyerabend, in which (...) individuals can be led to occlude the richness of their experience in ways that are existentially impoverishing. (shrink)

This paper presents a naturalistic response to the challenge of epistemic relativism. The case of the Azande poison oracle is employed as an example of an alternative epistemic norm which may be used to justify beliefs about everyday occurrences. While a distinction is made between scepticism and relativism, an argument in support of epistemic relativism is presented that is based on the sceptical problem of the criterion. A response to the resulting relativistic position is then provided on (...) the basis of a particularist response to scepticism combined with a naturalistic approach to the warrant of epistemic norms. It is argued that it is possible to comparatively assess the ability of epistemic norms to lead to epistemic aims. As against the epistemic relativist, it is possible to provide an objective basis for the choice between alternative epistemic norms. (shrink)

Throughout the writings of Paul Feyerabend, there are constant references to the historical contingency of the scientific enterprise, often accompanied by philosophical claims about the significance of that contingency. This paper presents those contingentist claims, situates them in the context of more recent work on the contingency of science, and offers an interpretation of their significance. I suggest that Feyerabend’s sense of contingency was connected to his defences of pluralism, and also to the ‘conquest of abundance’ narrative developed in the (...) very late writings. (shrink)

There are a number of debates that are relevant to questions concerning objectivity in science. One of the eldest, and still one of the most intensely fought, is the debate over epistemic relativism. —All forms of epistemic relativism commit themselves to the view that it is impossible to show in a neutral, non-question-begging, way that one “epistemic system”, that is, one interconnected set of epistemic standards, is epistemically superior to others. I shall call this view “No-metajustification”. No-metajustification is (...) commonly taken to deny the objectivity of standards. In this paper I shall discuss two currently popular attempts to attack “No-metajustification”. The first attempt attacks no-metajustification by challenging a particular strategy of arguing in its defence: this strategy involves the ancient Pyrrhonian “Problem of the Criterion”. The second attempt to refute No-metajustification targets its metaphysical underpinning: to wit, the claim that there are, or could be, several fundamentally different and irreconcilable epistemic systems. I shall call this assumption “Pluralism”. I shall address three questions with respect to these attempts to refute epistemic relativism by attacking no-metajustification: Can the epistemic relativist rely on the Problem of the Criterion in support of No-metajustification? Is a combination of Chisholmian “particularism” and epistemic naturalism an effective weapon against No-metajustification? And is Pluralism a defensible assumption? (shrink)

I argue that relativists about aesthetic and other evaluative language face some of the same objections as non-naturalists in ethics. These objections concern the metaphysics required to make it work. Unlike contextualists, relativists believe that evaluative propositions are not about the relation in which things stand to certain standards. Nevertheless, the truth of such propositions would depend on variable standards. I argue that relativism requires the existence of states of affairs very different from other things known to exist. Furthermore, (...) there seems to be no convincing reason to postulate such entities. However, if they do not exist, then relativism leads to an error theory. That is unattractive, as relativism was meant to preserve the truth of many evaluative claims. (shrink)

ABSTRACT Contemporary relativists often see their view as contributing to a semantic/post-semantic account of linguistic data about disagreement and retraction. I offer an independently motivated metasemantic account of the same data, that also handles a number of cases and empirical results that are problematic for the relativist. The key idea is that the content of assertions and beliefs is determined in part by facts about other times, including times after the assertion is made or the belief is formed. On this (...) temporal externalist view, speaker behaviours such as retraction of previous assertions play a role in making it the case that a past utterance has a given meaning. (shrink)

In 1957, Feyerabend delivered a paper titled ‘On the Quantum-Theory of Measurement’ at the Colston Research Symposium in Bristol to sketch a completion of von Neumann's measurement scheme without collapse, using only unitary quantum dynamics and well-motivated statistical assumptions about macroscopic quantum systems. Feyerabend's paper has been recognised as an early contribution to quantum measurement, anticipating certain aspects of decoherence. Our paper reassesses the physical and philosophical content of Feyerabend's contribution, detailing the technical steps as well as its overall philosophical (...) motivations and consequences. Summarising our results, Feyerabend interpreted collapse as a positivist assumption in quantum mechanics leading to a strict distinction between the uninterpreted formalism of unitary evolution in quantum mechanics and the classically interpreted observational language describing post-measurement outcomes. Thus Feyerabend took the no-collapse completion of the von Neumann measurement scheme to show the dispensability of the positivist assumption, leading the way to a realistic interpretation of quantum theory. We note, however, that there are substantial problems with his account of measurement that bring into question its viability as a legitimate foil to the orthodox view. We further argue that his dissatisfaction with the von Neumann measurement scheme is indicative of early views on theoretical pluralism. (shrink)

Recent research gives perspectivism the status of a stand-alone epistemological research program. As part of this development, it must be distinguished from other epistemologies, especially relativism. Not only do relativists and perspectivists use a similar vocabulary—even the supposed tenets (features of the doctrine) seem to partially overlap. To clarify the relation between these programs, I suggest drawing two important distinctions. The first is between the (1) terminological and (2) doctrinal components of epistemologies, the second between the (2a) analytical and (...) (2b) synthetic doctrinal components. The method of the originalistic linguistic analysis that I introduce in this article shows that both relativism and perspectivism use the same matrix of interconnected linguistic expressions that belong to what I call the universal epistemic language. Furthermore, this method reveals which doctrinal components necessarily follow from this linguistic basis and the terms ‘relativism’ and ‘perspectivism’ and which are a result of deliberate philosophical constructions. As for the linguistic basis and analytical doctrinal components, relativism and perspectivism are complementary members of one epistemology. Doctrinal additions that transform the original meaning of the terms ‘relativism’ and ‘perspectivism’, such as ‘indifferentism’ and ‘non-absolutism’, should always be explicitly mentioned to avoid confusion and straw men debates in philosophy.
