Quantum Theory and the Schism in Physics is one of the three volumes of Karl Popper’s Postscript to the Logic of scientific Discovery . The Postscript is the culmination of Popper’s work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science. Quantum Theory and the Schism in Physics is the third volume of the Postscript . It may be read independently, but it also forms part of Popper’s interconnected argument in (...) the Postscript . It presents Popper’s classic statement on quantum physics and offers important insights into his thinking on problems of method within science and physics as a whole. (shrink)

Realism and the Aim of Science is one of the three volumes of Karl Popper’s Postscript to the Logic of scientific Discovery. The Postscript is the culmination of Popper’s work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science. Realism and the Aim of Science is the first volume of the Postcript . Popper here formulates and explains his non-justificationist theory of knowledge: science aims at true explanatory theories, yet it can (...) never prove, or justify, any theory to be true, not even if is a true theory. Science must continue to question and criticise all its theories, even those that happen to be true. Realism and the Aim of Science presents Popper’s mature statement on scientific knowledge and offers important insights into his thinking on problems of method within science. (shrink)

The subjectivist-agnostic interpretation of the category of truth, which we examined in Part One, on "critical rationalism," has deep epistemological roots. Hence, Lenin's analysis of the epistemological intentions of "physical" idealism, which emerged at the end of the last century, is fully applicable to a description of the epistemological falsification of Karl Popper and his followers.

On the basis of careful textual exegesis and philosophical analysis, and contrary to the received view, Mark R. Wheeler demonstrates that Aristotle presents and systematically explicates his definition of the essence of the truth in the Metaphysics. Aristotle states the nominal definitions of the terms "truth" and "falsehood" as part of his arguments in defense of the logical axioms. These nominal definitions express conceptions of truth and falsehood his philosophical opponents would have recognized and accepted in the context of dialectical (...) argument. On the basis of these nominal definitions, Aristotle develops his definitions of the essences of truth and falsehood--his "real" definitions of truth and falsehood. Aristotle's methodical exposition of his essential definitions of truth and falsehood in the Metaphysics serves as a well-developed example of how his philosophical inquiry starts with nominal definitions and ends with real definitions. Wheeler also argues for the novel claim that Aristotle defines the most fundamental kind of truth in terms of accurate measurement. Aristotle's metrical conception of truth serves as the theoretical basis for specifying the truth conditions of various assertions, for identifying the sorts of beings implicated in these truth conditions, and for explaining the nature of approximate truth and falsehood. Far from offering us a minimal account of truth, Wheeler shows how Aristotle offers us a sophisticated and metrical theory of truth. (shrink)

Manifest Activity presents and critically examines the model of human power, the will, our capacities for purposeful conduct, and the place of our agency in the natural world of one of the most important and traditionally under-appreciated philosophers of the 18th century: Thomas Reid. For Reid, contrary to the view of many of his predecessors, it is simply manifest that we are active with respect to our behaviours; it is manifest, he thinks, that our actions are not merely remote (...) products of forces that lie outside of our control. Reid holds, instead, that actions are all and only those events that spring from active power and he produces insightful and imaginative arguments for the claim that only a creature with a mind is capable of having active power. He believes that only human beings, and creatures 'above us', are capable of directing events towards ends, of endowing them with purpose or direction, the distinctive feature of action. However, he also holds that all events, and not merely human actions, are products of active power, power possessed either by human beings or by God. This collection of theses leads Reid to the view that human behaviour and the progress of nature are both essentially teleological. Patterns in nature are the products of laws of which God is the author; patterns in human conduct are the products of character and the laws that individuals set for themselves. Manifest Activity examines Reid's arguments for this view and the view's implications for the nature of character, motivation and the special kind of causation involved in the production of human behavior.

ABSTRACT The individual-community relationship has always been one of the most fundamental topics of social sciences. In sociology, this is known as the micro-macro relationship while in economics it refers to the processes, through which, individual actions lead to macroeconomic phenomena. Based on philosophical discourse and systems theory, many sociologists even use the term "emergence" in their understanding of micro-macro relationship, which refers to collective phenomena that are created by the cooperation of individuals, but cannot be reduced to individual (...) actions. "Emergence" theories attempt to explain the nature of society as a complex system by examining how individuals and their relationships lead to the creation of integrated and macro-social phenomena such as markets, educational systems, cultural beliefs, and shared social practices. As a prelude to activity, every researcher has to answer the question from the methodological point of view, how is it possible to study the behavior of social groups and how can we gain knowledge about the laws related to social groups? Anyone who deals with humanities and social sciences or any reality and phenomenon that affects human beings, inevitably deals with the reality that is emerging. In fact, emergence occurs when one level of reality emerges radically from another level. Examples of emergent levels of reality include how the mind emerges from the body; or the way society emerges from human beings. Therefore, when there is an emerging factor, different scientific disciplines should be used, because it is inevitable to talk about social affairs, psychology and neurobiology, as well as physical and even chemical. -/- INTRODUCTION Since its beginning in the 19th century, sociology has faced the fundamental question of what a social phenomena stands for? At a glance, sociologists deal with the study of social groups, collective behavior, institutions, social structures, social networks, and social dynamics, and ultimately all such phenomena are composed of individuals. Therefore, social phenomena seem to have no independent ontological status, and in this case, sociology is ultimately about reducible individuals. Different approaches about the micro-macro relationship, using the concept of "emergence", argue that although collective phenomena are created by individuals, they cannot be reduced to individual action. The term "emergence" is used to distinguish "emergent results" from " Procedural results". Results are called Procedural that can only be calculated by adding or subtracting the causes that act together. On the contrary, they are emergent outcomes that are qualitatively novel compared to the causes from which they originate. An example of such emergent results is mental characteristics that emerge from neural processes, but are not considered among the characteristics of neural processes of components - which are their origin. Philosophical debates about emergentism and reductionism focus on the mind-brain relationship, but as many philosophers have noted, they can be generalized to apply to any hierarchical set of features. The cognitive revolution reactivated a 19th century controversy between theorists of Identity and dualism. The theorists of Identity believe in reductionist materialism and elimination of metaphysics, according to which the mind is nothing more than the biological, while the dualists believe that the mind and the brain are distinct from each other. Emergence has been considered as a third way between the theories of Identity and dualism. -/- METHODOLOGY Interdisciplinarity Is fundamentally indicated by the dominance of open systems as well as social and emerging systems at different levels. Therefore, as long as we are facing a new emergentism, there will necessarily be different fields and an interdisciplinary method. The commonality of social sciences and cognitive sciences on the issue of emergence provides the possibility of interaction and exchange of concepts between these two for deeper research. Therefore, in this research, apart from the concepts of Subvenience and downward causation, we have used multiple realization and wildly disjunctive, which are used to explain the emerging concept in cognitive sciences, including neurobiology, psychology, and philosophy. For analytical and interdisciplinary approaches, after examining the concepts of subvenience, and wildly disjunctive, Individualistic and collectivist emergentism have been reviewed. And then their adequacy is criticized and evaluated in meeting strong emergence conditions. -/- FINDINGS Philosophers of the mind have been able to define the conditions of irreducibility and downward causation, which are essential for strong emergence, by using the principle of subvenience with the help of multiple realization and wildly disjunctive principles. Therefore, by definition, emergentist individualism suffers from the problem of how to explain downward causality and irreducibility, and emergentist collectivism faces the challenge of reification. The analysis of the challenges facing the two methodological approaches of individualism and collectivism leads us to three unresolved issues about the emerging phenomenon, which are realism, downward causality, and mechanism. Despite the differences in the stances of these two approaches regarding the aforementioned triple problems, individualists and collectivists both agree that some social characteristics are reducible; and some others are irreducible due to their complexity, the determination of which, depends on the case study of the mechanism of emergence of each social characteristic. -/- CONCLUSION An emergence that is consistent with reductionism is called a weak emergence. And strong emergence includes the principle of irreducibility and downward causality. According to strong emergence, the characteristics of social phenomena have downward causal power, which cannot be reduced to the causal forces. The principle of subvenience, together with multiple realization and wildly disjunctive, can provide the conditions of irreducibility and downward causality, which are essential conditions of strong emergence. Based on the philosophical analysis of two methodological approaches, individualist and collectivist, it can be concluded that emergentist individualism suffers from the problem of how to explain downward causality and irreducibility, and reification collectivism faces the challenge of reification. The analysis of the problems faced by these two approaches leads us to three unresolved issues, which are realism, downward causality, and mechanism. individualist emergentists acknowledge the existence of emergent social characteristics, but despite this, they believe that these characteristics are not real but merely analytical constructs that require explanation based on individuals and their mutual actions. But collectivists argue that emergentism yields a categorical ontology and supports social realism. They accept the dependence of social characteristics on individuals, but claim that social entities and structures are ontologically independent. Individualists and collectivists both agree that some social characteristics are reducible; and others are irreducible due to their complexity; and the only way to recognize this is to engage in empirical studies of the mechanisms and temporal processes of "emergence" that create social characteristics. -/- NOVELTY The newness of this compact article is as follows: a) Presenting an interdisciplinary approach using the analysis of philosophy of cognitive sciences, including the philosophy of mind, neurobiology and psychology to formulate the issue of social emergence; b) Criticizing individualist and collectivist methodological approaches to the issue of social emergence and explaining the sufficiency and shortcomings of both in providing weak and strong emerging conditions; c) Explaining and categorizing the challenges facing methodological approaches in explaining the phenomenon of social emergence, in three categories: realism, downward causality, and mechanism.

We compare Karl Popper’s ideas concerning the falsifiability of a theory with similar notions from the part of statistical learning theory known as VC-theory . Popper’s notion of the dimension of a theory is contrasted with the apparently very similar VC-dimension. Having located some divergences, we discuss how best to view Popper’s work from the perspective of statistical learning theory, either as a precursor or as aiming to capture a different learning activity.

We introduce a subclass of Kripke's fixed points in which falsehood is the preferred truth value. In all of these the truthteller evaluates to false, while the liar evaluates to undefined (or overdefined). The mathematical structure of this family of fixed points is investigated and is shown to have many nice features. It is noted that a similar class of fixed points, preferring truth, can also be studied. The notion of intrinsic is shown to relativize to these two subclasses. The (...) mathematical ideas presented here originated in investigations of so-called stable models in the semantics of logic programming. (shrink)

1. A new wave of subjectivism in the theory of pictorial art began around forty years ago; and since then it has gathered pace in tandem with changing fashions in the philosophy of mind. The initial impetus was provided by the publication of Ernst Gombrich’s 1956 Mellon Lectures, Art and Illusion.1 In this book, and in many subsequent articles and lectures which elaborate its theme, Gombrich argues that the development of Western art – essentially the art of ancient (...) Greece and the art of Western Europe from Giotto to Cezanne – consists in a series of discoveries about the nature of visual perception, and the means by which the effect of visible objects on our senses can be simulated. ‘What may make a painting like a distant view through a window’ he writes, ‘is not the fact that the two can be as indistinguishable as is a facsimile from the original: it is the similarity between the mental activities both can arouse.’ And in another place: ‘The goal which the artist seeks with such self-critical persistence is … a psychological effect.’2 These remarks are concerned with a specific artistic tradition, and with specific pictorial devices, such as foreshortening and shading, which I shall not write about here. But Gombrich’s work launched a search for a general theory of depiction based on the same approach. The search intensified in the wake of Nelson Goodman’s Languages of Art, which persuaded most of its readers that the resemblance theory of depiction could not be made to work, but did not provide a plausible alternative to it. Today there is broad agreement among philosophers that the nature of pictorial art cannot be explained by analysing the relationship between the marks on the surface of a picture and the kinds of objects that they represent. The consensus is that it can only be explained by defining the psychological effect that these marks produce.3 Today, the two most influential theories of depiction that are guided by this general idea are Richard Wollheim’s and Christopher Peacocke’s..

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.

In Section 5 of his important paper, “Truth, Rationality, and the Growth of Knowledge,”’ Karl Popper discusses the requirements for knowledge to grow. According to Popper, a scientist often finds himself in the following problem-situation: A theory T that he has been using so far, while it can explain some facts, cannot explain others, and is falsified by still other facts. Consequently, the scientist desires to come up with a theory T‘ that will explain everything that T could (...) and at least some things that T could not, especially those facts which falsified T. Would not such a success, if we could emerge with a T’, be enough? Not so, claims Popper. Given that our aim is more and more interesting truth, “the logic of the general problem-situation” demands that T‘ satisfy other requirements as well. If these added requirements are not met, our aim of approach- ing truth would be vitiated.2 These additional requirements are three in all. First, that every new theory proposed, such as T‘, should proceed from some “simple, new, and powerful, unifying idea.” Second, that every new theory should be independently testable, and third, each such theory should pass some new, and severe, tests.3 Popper believes that the third requirement is crucial for the growth of knowledge, and he discusses it in considerable detail. My primary aim in this paper is to show that Popper’s arguments in support of his third requirement do not stand up. I shall argue that if knowledge can grow at all on Popper’s other assumptions then it can grow even if every new theory subsequent to the initial theory should violate Popper’s third requirement. In showing how knowledge can grow even though the third requirement is never satisfied, I use assumptions and methods which Popper allows himself. Hence, I leave open the question of the legitimacy of these assumptions and methods which have, in fact, been severely criticized by Adolf Grunbaum, David Miller, Pave1 Tichy, and others. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.2 (2001) 312-314 [Access article in PDF] Shook, John R. Dewey's Empirical Theory of Knowledge and Reality.The Vanderbilt Library of American Philosophy. Nashville: Vanderbilt University Press, 2000. Pp. ix + 316. Cloth, $46.00; Paper, $22.95. The current renaissance of American pragmatism, and John Dewey's philosophy in particular, began two decades ago with Richard Rorty's refashioning of Dewey as a postmodernist who renounces (...) the "professional philosophy" of metaphysics and epistemology for the fluidity of conversation in the life and growth of a community. This depiction, though praised for rekindling Dewey's star, has been widely challenged by subsequent commentators. Ralph Sleeper's 1986 The Necessity of Pragmatism persuasively argues that Dewey reconfigures, rather than renounces, the logical and metaphysical grounds of knowledge. Despite an archaic Hegelian vocabulary that misleadingly suggests idealism and antirealism, Sleeper finds Dewey advancing a genuine metaphysics of existence, not merely a conversation about experience: a naturalistic realism of independent existences that enter into and are transformed by human interactions with them.This perspective is shared by most Dewey scholars, including Sandra Rosenthal, Raymond Boisvert, and J. E. Tiles. At least until now. In a profound and provocative exploration of his early philosophy, John R. Shook, presents a compelling case that Dewey's reconstruction of metaphysics and epistemology is deeper than even Sleeper imagined. Dewey did not merely abandon idealism under the influence of William James, as most assume; he transformed it in a original way that, while wholly naturalistic, [End Page 312] is a fusion of idealism and realism that overcomes both the former's "mind-stuff" and the latter's "in-itself reality."Dewey began his philosophical odyssey with the searing desire to eradicate the dualisms of mind versus world, phenomenal versus noumenal, perceptual versus conceptual. Post-Hegelian idealists agreed that this division is ultimately reconciled in the "absolute," though they disagreed about whether the absolute is psychological or cosmological, social or supernatural, knowable or unknowable. From the very beginning, Shook argues, Dewey accepted the psychological path as sketched by James Ward, and also Edward Caird's claim that the absolute must be knowable in some sense. Intriguingly, the missing link between perception and conceptual awareness is Wilhelm Wundt's notion of volition: percepts are neither mechanically attached to concepts nor are they overlaid by Kantian "faculties of mind." Instead, a disruption of perceptual or noncognitive experience generates a desire for reconciliation that calls forth ideas that diagnose the problem and suggest ways to resolve it. Achieved solutions, in turn, forge a background of habitual dispositions that shape interpretations within the noncognitive realm.While still an idealist, then, Shook finds the essential elements of the "method of inquiry" that later anchored Dewey's instrumentalism and pragmatism. Prior to 1890, however, he still construed this as individual "mental activity," and the problem of its relation to God's Absolute Mind remained. Upon relinquishing the supernatural for the social, however, this final obstacle was eliminated. The dispositional background extends beyond the individual to the customs, traditions, and values of a culture—indeed, even the barest notions of "self" and "reality" are inconceivable without reference to such a background. This is Dewey's broad conception of "experience"—a humanistic naturalism with no trace of mind-stuff or subjectivism. In this sense Dewey is a realist, though his affirmation of things-themselves (including things we have not or may never actually discover) avoids the things-in-themselves that is the bane of metaphysical realism. To claim that things exist without an experiential background of how we may find them to exist is at best empty verbiage, and at worst hypnosis by the dervishes of dualism.Scrupulous in research, penetrating in detail, Shook's presentation is so faithful to Dewey that it will undoubtedly draw many of the same criticisms once hurled at the master. Though careful readers will be able to identify "experience" in its broadly social and functional sense, others will be confused by applications as diverse as "mental activity," "soul," "reality," "the history of the...

According to my interpretation, based on the entirety of Michael Polanyi's epistemological works, his theory of tacit knowing is conceived of as three models tied together by the central feature of Intellectual Passions as integrator. The models are progressively refined forms of his first conception of tacit knowing: ‘we know more than we can tell’. The three models are: the Gestalt-Perception Model based on the gestalt notion of part-whole relations, the Action-Guiding Model incorporating the phenomenological-existential notion of intentional action, (...) and the Semiotic Model, an abstract conception of action directed to meaning showing that tacit knowing has a ‘from-to structure’. In the Semiotic Model integration is named by the logical term ‘inference’. Polanyi's conception of reality and his theory of truth are introduced linked to the models, to show why his epistemology is not subjectivist and his theory of truth is not relativist. (shrink)

I offer two potential diagnoses of the behavioral norms governing post‐truth politics by comparing the view of language, communication, and truth‐telling put forward by David Lewis (extended by game theorists), and John Searle. My first goal is to specify the different ways in which Lewis, and game theorists more generally, in contrast to Searle (in the company of Paul Grice and Jurgen Habermas), go about explaining the normativity of truthfulness within a linguistic community. The main difference is that for Lewis (...) and game theorists, “truthful” signaling follows from an align- ment of interests, and deception follows from mixed motives leading to the calculation that sending false information is better for oneself. Following in the Enlightenment tradition, Searle argues that practical reasoning, which involves mastery of at least one language, requires that actors intend to communicate. This intention includes constraining the content of statements to uphold veracity conditions. After distinguishing between these two accounts, I will artic- ulate the implications for explaining, and even informing actions, constitutive of post‐truth politics. I argue that the strategic view of communication is suffi- cient neither to model everyday conversation nor to reflect a public sphere useful for democratic govern- ment. Both the pedagogy of strategic communication as cheap talk, and its concordance with new digital information technologies, challenge norms of truthful- ness that underlie modern institutions essential to an effective public sphere.

Based on a rather simple thesis that we can learn from our mistakes, Karl Popper developed a falsificationist epistemology in which knowledge grows through falsifying, or criticizing, our theories. According to him, knowledge, especially scientific knowledge, progresses through conjectures that are controlled by criticism, or attempted refutations . As he puts it, ‘Criticism of our conjectures is of decisive importance: by bringing out our mistakes it makes us understand the difficulties of the problem which we are trying to solve. This (...) is how we become better acquainted with our problem, and able to propose more mature solutions: the very refutation of a theory ... is always a step forward that takes us nearer to the truth. And this is how we can learn from our mistakes’ . Since criticism plays such a crucial role in Popper's falsificationist methodology, it seems natural to envisage his heuristic as a helpful resource for developing critical thinking. However, there is much controversy in the psychological literature over the feasibility and utility of his falsificationism as a heuristic. In this paper, I first consider Popper's falsificationism within the framework of his critical rationalism, elucidating three core and interrelated concepts, viz. fallibilism, criticism, and verisimilitude. Then I argue that the implementation of Popper's falsificationism means exposing to criticism various philosophical presuppositions that work against criticism, such as essentialism, instrumentalism, and conventionalism; it also means combating what seems a common tendency of humans to be biased towards confirmation. I examine the confirmation bias, to which Popper did not give much attention: its pervasiveness and various guises, some theoretical explanations for it, and the role of teachers in undermining its strength and spread. Finally, I consider the question whether students can and should be taught to use disconfirmatory strategies for solving problems. (shrink)

In this work Ockham proposes a theory of simple predication, which he uses in explicating the truth conditions of progressively more complicated kinds of propositions. His discussion includes what he takes to be the correct semantic treatment of quantified propositions, past tense and future tense propositions, and modal propositions, all of which are receiving much attention from contemporary philosophers. He also illustrates the use of exponential analysis to deal with propositions that prove troublesome in both semantic theory and (...) other disciplines, such as metaphysics, physics, and theology. This type of analysis plays an essential role in his substantive philosophical and theological works, and in many cases then can hardly be understood without a prior acquaintance with this section of the Summa. An introduction by Alfred J. Freddoso clarifies and summarizes Ockham's theory, discusses certain philosophical problems which it engenders, and proposes new interpretations for parts of it. The essay will be helpful both to those interested in Ockham as a historical figure and to those interested in his substantive systematic contributions to logical theory. (shrink)

This volume gathers together for the first time are all the key texts in a crucial debate in modern philosophy, centered on Leibniz's famous 1695 essay, the "New System of the Nature of Substances and their Communication," in which he introduced his strikingly original theory of metaphysics. His "system" became increasingly famous and drew him into discussion and development of these ideas, both in public and in private, with a variety of thinkers, most notably the great French philosopher Pierre (...) Bayle. Woolhouse's and Francks's new English edition gives the only full representation of this debate, and will therefore be essential reading for anyone who wishes to gain a proper understanding of Leibniz's philosophy and its intelletual context. All the texts are newly translated and extensively annotated; many appear in English for the first time. (shrink)

Based on a rather simple thesis that we can learn from our mistakes, Karl Popper developed a falsificationist epistemology in which knowledge grows through falsifying, or criticizing, our theories. According to him, knowledge, especially scientific knowledge, progresses through conjectures (i.e. tentative solutions to problems) that are controlled by criticism, or attempted refutations (including severely critical tests). As he puts it, ‘Criticism of our conjectures is of decisive importance: by bringing out our mistakes it makes us understand the difficulties of the (...) problem which we are trying to solve. This is how we become better acquainted with our problem, and able to propose more mature solutions: the very refutation of a theory... is always a step forward that takes us nearer to the truth. And this is how we can learn from our mistakes’ (1989, p. vii). Since criticism plays such a crucial role in Popper's falsificationist methodology, it seems natural to envisage his heuristic as a helpful resource for developing critical thinking. However, there is much controversy in the psychological literature over the feasibility and utility of his falsificationism as a heuristic. In this paper, I first consider Popper's falsificationism within the framework of his critical rationalism, elucidating three core and interrelated concepts, viz. fallibilism, criticism, and verisimilitude. Then I argue that the implementation of Popper's falsificationism means exposing to criticism various philosophical presuppositions that work against criticism, such as essentialism, instrumentalism, and conventionalism; it also means combating what seems a common tendency of humans to be biased towards confirmation. I examine the confirmation bias, to which Popper did not give much attention: its pervasiveness and various guises, some theoretical explanations for it, and the role of teachers in undermining its strength and spread. Finally, I consider the question whether students can and should be taught to use disconfirmatory strategies for solving problems. (shrink)

In 'On the nature of truth and falsehood' Russell offers both a multiple relation theory of judgment and a correspondence theory of truth. It has been a prevailing understanding of the Tractatus that Wittgenstein rejects Russell’s multiple relation idea but endorses the correspondence theory. Ramsey took the opposite view. In his 'Facts and Propositions', Ramsey endorses Russell’s multiple relation idea, rejects the correspondence theory, and then asserts that these moves are both due to Wittgenstein. This chapter (...) will argue that Ramsey’s ascriptions are both correct. The extent of the agreement between Ramsey and Wittgenstein will be argued, moreover, to count definitively against standard understandings of Ramsey as a redundancy theorist of truth. Wittgenstein is no correspondence theorist and Ramsey is no redundancy theorist; rather, both philosophers offer identity theories of truth. (shrink)

Herner Sæverot begins this article with an example: how Søren Kierkegaard used deceit as a means to educate. In one of his biographical texts, it turns out that Kierkegaard's objective was to deceive his readers into a totalized and universal truth. According to Sæverot, Kierkegaard's approach shows that he was a “demystifier,” someone who wants to save an other from delusion and bring this person into a better understanding of the world. Contrary to Kierkegaard, Sæverot argues that education is [im]possible—which, (...) he further maintains, may open up the possibility of being “educated.” Sæverot couches his argument in the context of a novel, Vladimir Nabokov's Lolita. Through a phenomenological study, Sæverot demonstrates how Nabokov creates deceits and adverse forces in his writings so as to open up a space of education, wherein the reader can take active part. The education of Nabokov is thus unpredictable and transformative. The ways in which Nabokov deceives and “educates” can, Sæverot ultimately contends, open up new domains for the field of educational theory. (shrink)

In this paper I examine five essential themes in Brand Blanshard's coherence theory of truth. Blanshard defines truth in terms of the rational or the interdependence of concepts, where concepts determine objects of experience rather than merely conform to them. On this view, truth is contextual and is the approximation of thought to reality or the systemization of the two ends - the immanent and transcendent. I raise some worries for this account of truth, foremost of which is (...) the worry that it commits us to a deep-seated skepticism, both theoretical and practical. In order to be able to tell when the immanent end is achieved and if it is making progress towards the transcendent end (i.e., when the ultimate systematization is realized), we require an omniscient standpoint of cosmic order or overarching system of beliefs. While this seems possible in principle it is not so in practice. (shrink)

ENGLISH ABSTRACT: Basic statements play a central role in Popper's "The Logic of Scientific Discovery", since they permit a distinction between empirical and non-empirical theories. A theory is empirical iff it consists of falsifiable statements, and statements (of any kind) are falsifiable iff they are inconsistent with at least one basic statement. Popper obviously presupposes that basic statements are themselves empirical and hence falsifiable; at any rate, he claims several times that they are falsifiable. In this paper we (...) prove that no basic statement is falsifiable, if the term 'basic statement' is to be understood according to Popper's definitions of that term. More precisely, we prove not only that no Popperian basic statement in the narrow sense of the word is falsifiable, but also that no Popperian basic statement in the broader sense, and even in the broadest possible sense, is falsifiable. This leads to the paradoxical result that, according to Popper's definitions of 'basic statement', the basis of the empirical sciences is not itself empirical. Furthermore, we point out a similar paradox as regards Popper's falsifiability scheme for theories. We close with a look at possibilities for overcoming these paradoxes. DEUTSCHE ZUSAMMENFASSUNG: Basissätze spielen eine zentrale Rolle in Poppers Logik der Forschung, denn sie erlauben die Unterscheidung zwischen empirischen und nichtempirischen Theorien: Eine Theorie ist empirisch genau dann, wenn sie aus falsifizierbaren Aussagesätzen besteht, und Aussagesätze (beliebiger Art) sind falsifizierbar genau dann, wenn sie mindestens einem Basissatz widersprechen. Popper setzt offensichtlich voraus, dassŸ die Basissätze selbst empirisch und somit falsifizierbar sind. Jedenfalls behauptet er mehrmals ihre Falsifizierbarkeit. Wir beweisen in unserem Aufsatz, dassŸ die Basissätze nicht falsifizierbar sind, und wir beweisen dies nicht nur für Poppersche Basissätze im engeren Sinn, sondern auch für Poppersche Basissätze im weiteren Sinn und schlieߟlich für Poppersche Basissätze im weitesten, mit den Vorstellungen Poppers gerade noch verträglichen Sinn. Dies führt zu dem paradoxen Ergebnis, dass nach Poppers eigenen methodologischen Postulaten die Basis der empirischen Wissenschaften nicht selbst empirisch ist. Darüber hinaus entwickeln wir ein ähnliches Paradoxon bezüglich Poppers Falsifizierbarkeitsschema für Theorien. Zum AbschlussŸ unseres Aufsatzes betrachten wir einige Möglichkeiten, die von uns entdeckten Paradoxa zu überwinden. (shrink)

While developing his theory of world 3, Popper rejects two claims made by Plato: first, that the inhabitants of world 3, ideas, are a source of ultimate explanation, a divine revelation of truth, and second, that these ideas are unchanging. I will rehabilitate the second claim. Man does not construct world 3 by creating his theories, nor is it a source of ultimate truth. Instead, world 3 is discovered by man, and it destroys some of his theories: destructive Platonism. (...) I discuss the impact of the modified position on the Grundlagenstreit in mathematics, taking into account Gillies’s constructive Aristotelianism. I then turn to the philosophy of computers and discuss how destructive Platonism relates to computers and the Internet. In particular, I criticize Popper’s claim that computers are nothing but elaborate pens as too pessimistic and incautious, and the fashionable “singularity” theory as too optimistic and at the same time too fatalistic. In my closing remarks, as an antidote against both views, I provide a more modest and reasonable speculation about the ultimate goal and meaning of life. (shrink)

This classic remains one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history.

David Lewis presented Convention as an alternative to the conventionalism characteristic of early-twentieth-century analytic philosophy. Rudolf Carnap is well known for suggesting the arbitrariness of any particular linguistic convention for engaging in scientific inquiry. Analytic truths are self-consistent, and are not checked against empirical facts to ascertain their veracity. In keeping with the logical positivists before him, Lewis concludes that linguistic communication is conventional. However, despite his firm allegiance to conventions underlying not just languages but also social customs, he pioneered (...) the view that convening need not require any active agreement to participate. Lewis proposed that conventions arise from “an exchange of manifestations of a propensity to conform to a regularity” (87–8). In reasserting the conventional quality of languages and other practices resting on mutual expectations, Lewis comfortably works within the analytic tradition. Yet he also deviates from his predecessors because his conventionalist approach is comprehensively grounded in instrumentalism. Lewis adopts an extension of David Hume's desire-belief psychology articulated in rational choice theory. He develops his philosophy of convention relying on the highly formal mid-twentieth-century expected utility and game theories. This attempt to account for language and social customs wholly in terms of instrumental rationality has the implication of reducing normativity to preference satisfaction. Lewis’ approach continues in the trend of undermining normative political philosophy because institutions and practices arise spontaneously, without the deliberate involvement of agents. Perhaps Lewis’ Convention is best seen as a resurgent form of analytic philosophy, characterized by “a style of argument, hostility to [ambitious] metaphysics, focus on language, and the dominance of logic and formalization” that solves the dilemma of “combining the analytic inheritance…with normative concerns” by reducing normativity to individuals’ preference fulfillment consistent with the axioms of rational choice.

In his recent book Christian Hermeneutics, James Fodor observes that ‘although Christians have from the very beginning been interested in living truthful, obedient lives … they have not exhibited the same passion for developing their own distinctive theory of truth’.1 Yet ‘the task confronting contemporary theology … is that of the rehabilitation or recovery of a distinctively Christian vision of truth’.2 To his credit, Fodor has attempted to rectify this state of affairs: first, by critiquing some of the more (...) prominent theories of truth from a Christian point of view, and secondly, by sketching some of the essential elements of a uniquely Christian understanding or conception of truth. In this article, I present a detailed analysis of Fodor’s alethic musings, and argue that they are both logically and theologically unsound. (shrink)

Karsavin's social ideas in many respects determined his relation to the Russian Revolution and the Bolshevik order. In full accord with his theory of the symphonic person, the broad and mass character of the processes that brought the Bolsheviks to power and enabled them to hold on to it was for Karsavin a sufficient reason to recognize the historical justification of the new order and to expect positive fruits from it. Of course, he never abandoned the standards of Christian (...) ethics in his evaluation of the practice of bolshevism; he was quite harsh in his denunciations of murders and persecutions. Nor did he descend to "Change of Landmarks" capitulationism, stressing more than once: "To understand the truth of what is happening does not mean to 'change landmarks' without qualification and, having lost face, to become appendages of the Communists." Although he was willing to allow, together with the "Change of Landmarks" people, that the Bolsheviks preserved Russia and its statehood from total collapse, he, in contrast to them, firmly asserted that what was needed was not submission to bolshevism but determined quests for a valid strategy to overcome it. Nonetheless, of all our religious thinkers, it was indisputably he who went further than anyone else in accepting and approving Bolshevik policy, who was inclined to believe in the fruitfulness of the Soviet experiment. This far-reaching acceptance was already clearly expressed in a short chapter on revolution that Karsavin appended to his Philosophy of History [Filosofiia istorii]. This acceptance was later intensified and actively defended in articles and public speeches, and it achieved its absolute apogee in the period of the philosopher's participation in the Eurasian movement.

Much recent work in the philosophy of language has been concerned with the project of constructing a theory of reference and truth for natural languages. I shall discuss certain assumptions which have been tacitly in the background of most of this work; what I hope my rather sceptical discussion will show is that the project of giving a theory of reference and truth is much more problematic - and more closely tied to questions of general philosophical interest - (...) than is usually suspected.

_Conjectures and Refutations_ is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

Intersubjectivity refers to one person’s awareness in relation to another person’s awareness. It is key to well-being and human development. From infancy to adulthood, human interactions ceaselessly contribute to the flourishing or impairment of intersubjectivity. In this work, we first describe intersubjectivity as a hallmark of quality dyadic processes. Then, using parent-child relationship as an example, we propose a dyadic active inference model to elucidate an inverse relation between stress and intersubjectivity. We postulate that impaired intersubjectivity is a manifestation (...) of underlying problems of deficient relational benevolence, misattributing another person’s intentions, and neglecting the effects of one’s own actions on the other person. These problems can exacerbate stress due to excessive variational free energy in a person’s active inference engine when that person feels threatened and holds on to his/her invalid beliefs. In support of this dyadic model, we briefly describe relevant neuroimaging literature to elucidate brain networks underlying the effects of an intersubjectivity-oriented parenting intervention on parenting stress. Using the active inference dyadic model, we identified critical interventional strategies necessary to rectify these problems and hereby developed a coding system in reference to these strategies. In a theory-guided quantitative review, we used this coding system to code 35 clinical trials of parenting interventions published between 2016 and 2020, based on PubMed database, to predict their efficacy for reducing parenting stress. The results of this theory-guided analysis corroborated our hypothesis that parenting intervention can effectively reduce parenting stress if the intervention is designed to mitigate the problems of deficient relational benevolence, under-coupling, and over-mentalizing. We integrated our work with several dyadic concepts identified in the literature. Finally, inspired by Arya Nagarjuna’s Buddhist Madhyamaka Philosophy, we described abstract expressions of Dependent Origination as a relational worldview to reflect on the normality, impairment, and rehabilitation of intersubjectivity.

Determinist thought with its sui generis view on life, nature and being as a whole is a point of view that could be observed in many different cultures and beliefs. It was thanks to Greek thought that it ceased to be a cultural element and transformed into a systematic cosmology. Schools such as Leucippos, then Democritos and Stoa attempted to integrate the determinist philosophy into ontology and cosmology. In the course of time, physics and metaphysics-based determinism approaches were introduced, and (...) a wide spectrum has emerged from genetics to behaviorism, from culture to psychology, from atomism to divinity. Determinism, whether physical or metaphysical origin, ignores freedom of will and deny agency competence over human behavior. Due to this feature, it is opposed by ethical theories, legal philosophies and religions. When the arguments for determinism are possible to disprove logically and philosophically, this is not so easy when the claims base themselves on scientific base. As the logical consequence of this novel fact, it is important to question the epistemological value of scientific knowledge and critically analyze the data of experiments and clinical studies in terms of methodology when answering any hypothesis such as neuro-biological, neuro-psychological, or neuro-theological argumentations. On the other hand, it is necessary to reach alternative experiments on the same subject or to show that it is possible to interpret them in different ways, as in the example of the Libet experiment. The neurobiological determinism based on biological reductionism, emerged as the result of ignoring the ontological difference of the mind, equating the mind with the brain, or defining mentality as an epiphenomenon of the brain. The main divergence stems from the acceptance of materialist philosophy. Paradigms that reduce existence only to matter do not take the metaphysical possibilities into account. In this case, although the problems called qualia or subjective experience stand there unresolved, the claim is preserved. Although many new developments such as the discovery of the entropy law, the big bang theory, and quantum physics have shaken the materialist philosophy, modern science resists an epistemological revision. However, with the current epistemology, it does not seem possible to grasp both the universe and the being as a whole. This is the most important reason why every attempt to understand the nature and spiritual side of human beings fails despite numerous experiments on the brain. However, the human brain is an organ that seems sophisticated and its secrets cannot be easily solved. Since there is not enough information about the brain, there is not enough evidence to claim that the brain, and therefore the mind, are part of the deterministic universe. Increasing brain researches since the last quarter of the twentieth century has revealed that genes, neurons and particularly brain chemistry claim much greater role than expected in human behavior. These results have been instrumentalized by some researchers for a radical claim that free will is an illusion, while by others it has led to the acceptance of will as less important over actions than was thought. Both ideas adopted a model of biological determinism in which freedom of will was ignored. Hypotheses based on controversial interpretations of various experiments raised concerns about religious, moral, and legal responsibility. Although man cannot be thought of as a non-free being from the point of view of common sense, the smog screen over the truth would not be lifted unless the scientific data in question had a correct interpretation. At first glance, it seems unreasonable to discuss universal determinism in the quantum universe. Nevertheless, the claim that strong causality prevails in the material world, including consciousness, remains in place. Therefore, firstly criticizing determinism and then examining biological determinism will help to fix the conceptual framework. This article aims to explain why genetics and neurobiology, while acknowledging their importance in the realization of behavior, can’t completely abolish moral agency. Some hypotheses attribute consciousness and free will to the physico-shimic structure of the brain, the random activity of neurons, or the ability to automatically transform inputs into outputs with the advantage of genetic information. This is the most sensitive and important point of being human; it attacks free will. Paradoxically, while global civilization of our time promises infinite freedom to human beings the science of the same age tries to prove that it is not free. (shrink)

In this long-awaited volume, Jeremy Shearmur and Piers Norris Turner bring to light Popper's most important unpublished and uncollected writings from the time of The Open Society until his death in 1994. After The Open Society: Selected Social and Political Writings reveals the development of Popper's political and philosophical thought during and after the Second World War, from his early socialism through to the radical humanitarianism of The Open Society. The papers in this collection, many of which are (...) available here for the first time, demonstrate the clarity and pertinence of Popper's thinking on such topics as religion, history, Plato and Aristotle, while revealing a lifetime of unwavering political commitment. After The Open Society illuminates the thought of one of the twentieth century's greatest philosophers and is essential reading for anyone interested in the recent course of philosophy, politics, history and society.

The ‘task confronting contemporary theology’, says James Fodor, ‘is that of the rehabilitation or recovery of a distinctively Christian vision of truth’ (Christian Hermeneutics[Oxford, 1995] p. 72). In this paper I examine Fodor's attempt to construct a Christian or transformational theory of truth. I argue that his analysis of truth in terms of transformation leads to a concept of truth which is both subjective and relative. I argue further that Fodor's truth theory is either committed to a version (...) of creative anti‐realism, according to which the existence of basic structure of the world is determined by our linguistic activities, or it implies that although our language doesn't correspond to the world, we should go on making our theological truth claims anyway. I conclude that Fodor's Christian theory of truth is in most crucial respects not Christian at all. (shrink)

The basic theme of Popper's philosophy--that something can come from nothing--is related to the present situation in physical theory. Popper carries his investigation right to the center of current debate in quantum physics. He proposes an interpretation of physics--and indeed an entire cosmology--which is realist, conjectural, deductivist and objectivist, anti-positivist, and anti-instrumentalist. He stresses understanding, reminding us that our ignorance grows faster than our conjectural knowledge.

This is a challenging and original work on the concept of justification and its application to ethical statements. The book divides into two parts. The first part is devoted to a systematic treatment of the nature of justification. It begins with a critical rejection of the deductive model. Wellman presents plausible arguments for the existence of non-deductive evidences in ethics and shows how ethical theories can be tested by "thought-experiment" as analogous to the confirmation of scientific theories by laboratory trials. (...) An interesting kind of inference termed "conductive reasoning" is described. It is argued that this third form of reasoning can be validly used in justifying ethical conclusions. Distinctive of conductive reasoning is its non-formal and inconclusive feature. Its validity is alleged to lie in its dependence upon the content of the argument. But by and large there is no way to judge the validity of these basic ethical arguments but by thinking them through and feeling their logical force." Wellman goes on to develop a challenge-response model for understanding the nature of justification. Justification is "to be understood essentially as a process of responding to challenges made." However, Wellman makes no attempt to consider the role of moral concepts in determining the validity of conductive reasoning and its role in the justification of ethical statements. Part II considers the dimensions of ethical justification in terms of the model of challenge and response. Seven species of challenge are described: truth, truth-value, meaningfulness, validity, validity-value, competence, and knowability. On the whole the book contains challenging views and material for the epistemology of ethics.--A. S. C. (shrink)

The Metaphysics of Good and Evil is the first, full-length contemporary defence, from the perspective of analytic philosophy, of the Scholastic theory of good and evil - the theory of Aristotle, Augustine, Aquinas, and most medieval and Thomistic philosophers. Goodness is analysed as obedience to nature. Evil is analysed as the privation of goodness. Goodness, surprisingly, is found in the non-living world, but in the living world it takes on a special character. The book analyses various kinds of (...) goodness, showing how they fit into the Scholastic theory. The privation theory of evil is given its most comprehensive contemporary defence, including an account of truthmakers for truths of privation and an analysis of how causation by privation should be understood. In the end, all evil is deviance - a departure from the goodness prescribed by a thing's essential nature. Key Features: Offers a comprehensive defence of a venerable metaphysical theory, conducted using the concepts and methods of analytic philosophy. Revives a much neglected approach to the question of good and evil in their most general nature. Shows how Aristotelian-Thomistic theory has more than historical relevance to a fundamental philosophical issue, but can be applied in a way that is both defensible and yet accessible to the modern philosopher. Provides what, for the Scholastic philosopher, is arguably the only solid metaphysical foundation for a separate treatment of the origins of morality. (shrink)

Liberals and Marxists alike have had a stake in making Marx non?liberal in theory and anti?liberal in practice. My re?reading of his work and life emphasizes the considerable overlaps and continuity between his views and activities and the liberalism of his day and ours. Marx?s critique of liberalism thus becomes subtler and less easily dismissed by liberals, who would do well to confront the violence and class struggle inherent in the success of the liberal project, rather than to erase (...) this in favour of an idealized doctrine and sanitized history. I identify an irony in that Marx politicized reason and reasonableness long before anti?foundational ?post?Marxists? developed their ?political? critique of traditional Marxist conceptions of truth and science.

The way in which knowledge progresses, and especially our scientific knowledge, is by unjustified anticipations, by guesses, by tentative solutions to our problems, by conjectures. These conjectures are controlled by criticism: that is, by attempted refutations, which include severely critical tests. They may survive these tests; but they can never be positively justified: they can neither be established as certainly true nor even as 'probable'. Criticism of our conjectures is of decisive importance: by bringing out our mistakes it makes us (...) understand the difficulties of the problems which we try to solve. This is how we become better acquainted with our problem, and able to propose more mature solutions: the very refutation of a theory - that is, of a tentative solution to our problem - is always a step forward that takes us nearer the truth. And this is how we can learn from our mistakes. As we learn from our mistakes our knowledge grows, even though we may never know - that is, know for certain. Since our knowledge can grow, there can be no reason here for despair of reason. And since we can never know for certain, the can be no authority here for any claim to authority, for conceit over our knowledge, or for smugness. The essays and lectures of which this book is composed apply this thesis to many topics, ranging from problems of the philosophy and history of the physical and social sciences to historical and political problems.

In Michael Ruse's recent publications, such as Taking Darwin Seriously (1998) and Evolutionary Naturalism (1995), he has advocated a certain sort of evolutionary epistemology and has argued that it implies a rejection of metaphysical realism (MR) in favor of a position that he calls “internal realism” (IR). Additionally, he has maintained that, insofar as his evolutionary epistemology implies a rejection of MR in favor of IR, it escapes the kind of argument against naturalism that Alvin Plantinga makes in his Warrant (...) and Proper Function (1993). In this article I explain the relevant views and arguments of Ruse and Plantinga, and I critically engage with Ruse's views, arguing that (1) his case for rejecting MR has no essential connection to evolutionary considerations; (2) his case for rejecting MR depends upon internalist assumptions about the nature of knowledge that are in need of some kind of defense; and (3) given his implicit internalism and his commitment to IR, his argument for rejecting MR can be used against his IR.

In his account of probable reasoning, Poincare used the concept, or at least the language, of conventions. In particular, he claimed that the prior probabilities essential for inverse probable reasoning are determined conventionally. This paper investigates, in the light of Poincare's well known claim about the conventionality of metric geometry, what this could mean, and how it is related to other views about the determination of prior probabilities. Particular attention is paid to the similarities and differences between Poincare's conventionalism (...) as it applies to probabilities and de Finetti's subjectivism. The aim of the paper is to suggest that in accounts of the development of ideas about probable reasoning, particularly those customarily described as Bayesian, Poincare's discussion deserves more attention than it has so far received.

ABSTRACT This article is written in the field of the philosophy of science. The aim is to express how painting and drawing can be used as part of a phenomenological research method. The painter or drawer is a visual researcher in the process of capturing a holistic and truthful experience of a cultural phenomenon. We will highlight the visual researcher process and how the experience of truth is known throughout this process. The paining and sketches, which we present in this (...) article, are part of a book, together with written narratives and pedagogical theory – on teaching as a phenomenon – called Lærerpraksis og Pedagogisk teori. The paintings and drawings present teaching in a way that complements and expands the written text. The sketches and painting of teaching attempt to establish the truth as unconcealment of a phenomenon. Our argumentation is based on the theories of Gadamer, Cassirer, Panofsky and Heidegger. Gadamer connects humanistic research with artistry and the experience of truth. Cassirer argues that the perception of a cultural phenomenon begins as a holistic understanding to bring forth the symbolic form or essence of the phenomenon. Panofsky transfers the theory of Cassirer into the field of painting. The concept of synthetic intuition is the intrinsic knowing of a painting, which corresponds to Cassirer’s concept of symbolic forms. Heidegger’s theory explores how art unfolds and preserves the truth. We will argue that the connection between art and truth could bring forth important perspectives on phenomenological science and turn the research activity closer to an artistic form. (shrink)

In this most recent book in an evolving series of foundational works in philosophy, semiotics, and theology, Neville probes into the nature and function of that class of signs that have an astonishing power to transform selves and communities. In unfolding what, for him, are the essential ingredients in religious symbols, he uses some of the categories and phenomenological descriptions that have done service in his other works. Particularly, he brings to bear on symbols his analysis of the creator/creation (...) relationship, his privileging of value over form, and the nature of determinateness and its boundary. At the same time, he puts pressure on any semiotic theory that would engulf the uniqueness of religious symbols under a pseudogeneric understanding of codes. (shrink)
