Because physical theories typically predict numerical values, an improvement in experimental precision reduces the tolerance range and hence increases corroborability. In most psychological research, improved power of a statistical design leads to a prior probability approaching 1/2 of finding a significant difference in the theoretically predicted direction. Hence the corroboration yielded by "success" is very weak, and becomes weaker with increased precision. "Statistical significance" plays a logical role in psychology precisely the reverse of its role in physics. This problem is (...) worsened by certain unhealthy tendencies prevalent among psychologists, such as a premium placed on experimental "cuteness" and a free reliance upon ad hoc explanations to avoid refutation.

While many philosophers of science have accorded special evidential significance to tests whose results are "novel facts", there continues to be disagreement over both the definition of novelty and why it should matter. The view of novelty favored by Giere, Lakatos, Worrall and many others is that of use-novelty: An accordance between evidence e and hypothesis h provides a genuine test of h only if e is not used in h's construction. I argue that what lies behind the intuition that (...) novelty matters is the deeper intuition that severe tests matter. I set out a criterion of severity akin to the notion of a test's power in Neyman-Pearson statistics. I argue that tests which are use-novel may fail to be severe, and tests that are severe may fail to be use-novel. I discuss the 1919 eclipse data as a severe test of Einstein's law of gravity.

It is argued that philosophical realism is well suited to serve as a perspective from which to understand nursing, and that it should be considered as an alternative to positivist, interpretivist, hermeneutical and phenomenological approaches. However, existing forms of realism, including theory and entity realism are shown to be faced with serious problems. In response, an alternative form ‘constraint realism’ is outlined, and shown to be apposite for illuminating the rule or convention governed behaviour characteristic of human beings. A brief (...) sketch is offered of its application to the social practice of nursing. (shrink)

A belief common among philosophers and biologists alike is that Mendelian genetics has been or is in the process of being reduced to molecular genetics, in the sense of formal theory reduction current in the literature. The purpose of this paper is to show that there are numerous empirical and conceptual difficulties which stand in the way of establishing a systematic inferential relation between Mendelian and molecular genetics. These difficulties, however, have little to do with the traditional objections which have (...) been raised to reduction. (shrink)

Sometimes a theory is interpreted realistically--i.e., as literally true--whereas sometimes a theory is interpreted instrumentalistically--i.e., as merely a convenient device for summarizing, systematizing, deducing, etc., a given body of observable facts. This paper is part of a program aimed at determining the basis on which scientists decide on which of these interpretations to accept a theory. I proceed by examining one case: the nineteenth-century debates about the existence of atoms. I argue that there was a gradual transition from an instrumentalist (...) to a realistic acceptance of the atomic theory, because of gradual increases in its predictive power, the "testedness" of its hypotheses, the "determinateness" of its quantities, and because of resolutions of doubts about the acceptability of its basic explanatory concepts.

In this essay it is argued that (1) if the process of scientific inquiry were to continue foreever, then science would ultimately terminate in the acceptance of a single theoretical framework better than all conceivable others, and (2) there is some evidence in favor of the view that science will continue unto eternity but no evidence in favor of the contrary view. In arguing for claim (1) it is claimed that if we are to understand the sense in which science (...) is progressive we must mean either that science progresses by approximating a final goal which, given an infinite process, will be attained, or that science progresses simply in the sense of expanding a body of funded knowledge such that, given an infinite process, the body of funded knowledge expands ad infinitum. That the second member of this disjunct is false and that the first cannot be shown to be false follows largely from a discussion and rejection of all available arguments (five) against the hypothesis proposed in (1). Further, an argument provided by Peirce (and suitably supplemented) provides additional positive evidence for the truth of the first member. No such argument exists for the truth of the second member. In arguing for claim (2) it is held that evidence in favor of a belief can be purchased by the positive moral value likely to occur as a result of accepting the beliefs, and that there is at least one moral value which accrues to the belief that inquiry will continue forever but which does not accrue to the belief that inquiry will not continue forever. In short, while there is no systematic evidence for or against the view that inquiry will continue forever, we have the right (and duty) to believe that inquiry will continue forever but we do not have the right (and duty) to believe the contrary.

The paper sets up a general framework for defining the notion of verisimilitude. Popper’s own account of verisimilitude is then located within this framework; and his account is defended on the grounds that it can be seen to provide a reasonable structural or Pareto criterion, rather than a substantive criterion, of verisimilitude. Some other criteria of verisimilitude that may be located within the framework are also considered and their relative merits compared.

The pragma-dialectical research program begins with a philosophical estate, in which a conception of reasonableness is offered that must serve as ground for the theoretical estate. Pragma-dialectics has produced many important insights in the theoretical estate, including the ideal model and the rules for critical discussions. However, here I will argue that the conception of reasonableness that the pragma-dialecticians adopt in the philosophical estate, based on anti-dogmatism, assumption of fallibilism and willingness to engage in critical discussion, is too narrow to (...) support the whole system of pragma-dialectical rules. What the philosophical estate requires is a broad and rich conception of excellent performance in argumentative practice, which then the rules of the critical discussion are intended to capture systematically in the theoretical estate. In my view, a virtue approach to argumentation is the ideal framework for such a philosophical ground. Virtues such as intellectual empathy, intellectual honesty, faith in reason, or recognition of reliable authority, point towards aspects of a philosophical conception of excellent arguing that are absent in the pragma-dialectical view of reasonableness. Finally, I will argue that what pragma-dialecticians call “second-order conditions” for a critical discussion are better understood as minimal argumentative virtue, a basic degree of virtue that arguers are required to possess in order to be prepared to participate in a fruitful critical discussion. The possession of such a basic degree of argumentative virtue is, I believe, what we mean when we characterise someone as reasonable. (shrink)

Interactionism holds that explanatory and interpretive projects are mutually enriching. If so, then the evolutionary and cognitive science of religions’ explanatory theories should aid interpretive projects concerning religious meaning. Although interpretive accounts typically focus on the local and the particular, interpreters over the past century have construed Freud and Marx as offering general interpretive theories. So, precedent for general interpretive theorizing exists. 4E cognitive science, which champions how cognition is embedded in natural and cultural settings, extended into external structures, enacted (...) via motor routines, and embodied via representations rooted in human bodily form, has encouraged interpretive researchers. Theories of embodied cognition especially have embraced a sweeping view of meaning that attends to the emotions’ role and to their evolutionary origins. That inspires a 6E cognitive science that attends to the emotional and evolved dimensions of cognition too and opens up the possibility of general interpretive theories of broadly Darwinian character. Evolved cognitive systems qualify as maturationally natural cognition, which exhibits a distinctive constellation of features. The by-product theory holds that religious representations’ engagement of maturationally natural cognition fosters religions’ success. Representations with some minimal violation of intuitive expectations concerning some ontological category grab attention, stick in memory, and preserve the many automatic inferences accompanying the category. The empirical evidence for this and other elaborations of the by-product view suggests that it discloses dynamics of evolved cognition and associated emotions that tend to guide the pursuit of religious meanings systematically toward well-worn grooves in the semantic landscape.

In a recent paper in this journal, entitled ‘Scientific Progress: Why Getting Closer to Truth is Not Enough’ (2017), Moti Mizrahi argues that the view of progress as approximation to the truth or increasing verisimilitude is plainly false. The key premise of his argument is that on such a view of progress, in order to get closer to the truth one only needs to arbitrarily add a true disjunct to a hypothesis or theory. Since quite clearly scientific progress is not (...) a matter of adding true disjuncts to theories, the argument goes, the view of progress as approximation to the truth is untenable. We show that the key premise of Mizrahi’s argument is false: according to verisimilitude-based accounts of progress, adding arbitrary true disjuncts to existing theories is just not enough to get closer to the truth.

Imre Lakatos gained fame in the English-speaking world as a follower and critic of philosopher of science Karl Popper. However, Lakatos’ background involved other philosophical and scientific sources from his native Hungary. Lakatos surreptitiously used Hegelian Marxism in his works on philosophy of science and mathematics, disguising it with the rhetoric of the Popper school. He also less surreptitiously incorporated, particularly in his treatment of mathematics, work of the strong tradition of heuristics in twentieth century Hungary. Both his Marxism and (...) his emphasis on heuristics contained a view of science and mathematics that contrasted with the mainstream of Anglo-American philosophy of science. Both involved a dynamic view of science, whether historical or psychological, and an emphasis on practice as opposed to static, formal representations of scientific theories. (shrink)

ABSTRACTWhile conspiracies have always been with us, conspiracy theories are more recent arrivals. The framing of conspiracy theories as rooted in erroneous or delusional belief in conspiracies is characteristic of “positive” approaches to the topic, which focus on identifying the causes and cures of conspiracy theories. “Critical” approaches, by contrast, focus on the historical and cultural construction of the concept of conspiracy theory itself. This issue presents a range of essays that cut across these two broad approaches, and reflect on (...) the problematic relationship between conspiracy theory and democratic politics. (shrink)

We historically trace various non-conventional explanations for the origin of the cosmic microwave background and discuss their merit, while analyzing the dynamics of their rejection, as well as the relevant physical and methodological reasons for it. It turns out that there have been many such unorthodox interpretations; not only those developed in the context of theories rejecting the relativistic paradigm entirely but also those coming from the camp of original thinkers firmly entrenched in the relativistic milieu. In fact, the orthodox (...) interpretation has only incrementally won out against the alternatives over the course of the three decades of its multi-stage development. While on the whole, none of the alternatives to the hot Big Bang scenario is persuasive today, we discuss the epistemic ramifications of establishing orthodoxy and eliminating alternatives in science, an issue recently discussed by philosophers and historians of science for other areas of physics. Finally, we single out some plausible and possibly fruitful ideas offered by the alternatives. (shrink)

Karl Popper developed a theory of deductive logic in the late 1940s. In his approach, logic is a metalinguistic theory of deducibility relations that are based on certain purely structural rules. Logical constants are then characterized in terms of deducibility relations. Characterizations of this kind are also called inferential definitions by Popper. In this paper, we expound his theory and elaborate some of his ideas and results that in some cases were only sketched by him. Our focus is on Popper's (...) notion of duality, his theory of modalities, and his treatment of different kinds of negation. This allows us to show how his works on logic anticipate some later developments and discussions in philosophical logic, pertaining to trivializing connectives, the duality of logical constants, dual-intuitionistic logic, the conservativeness of language extensions, the existence of a bi-intuitionistic logic, the non-logicality of minimal negation, and to the problem of logicality in general.

The traditional conception of knowledge is justified, true belief. If one looks at a modern textbook on epistemology, the great bulk of questions with which it deals are to do with personal knowledge, as embodied in beliefs and the proper experiences that someone ought to have had in order to have the right (or justification) to know. I intend to argue that due to the explosive growth of knowledge whose domain is “outside the head”, this conception has outlived its relevance. (...) -/- On the other hand, Karl Popper’s (1934) Falsificationism, with its emphasis on the objective character of knowledge, is not only a sounder, but also a more appropriate theory of knowledge for understanding the nature and growth of civilization. Later, Popper (1945) generalized this approach to obtain critical rationalism, in which all claims to knowledge, whether scientific or otherwise, are understood as objective solutions to objective problems and can be evaluated by other non-observational - types of criticism. I will first argue that Popper’s methodology is quite suited to the view that knowledge is an objective autonomous product and then adduce his theory of world 3, an ontology that neatly wraps up various considerations. World 3 is the domain of abstract products of the human mind that now have a life of their own, outside of human heads: theories, arguments, problems, plans, etc. I then adduce some other arguments for the autonomous quality of knowledge.

ABSTRACT:In this article I inquire into Confucian ethics from a non-ideal stance investigating the complex interaction between Confucian ideals and the reality of the modern workplace. I contend that even Confucian workers who regularly engage in social rites at the workplace have an internal, Confucian reason to appreciate the value of rights at the workplace. I explain, from a Confucian non-ideal perspective, why I disagree with the presumptuous idea that labor (or workplace) rights are necessarily incompatible with Confucian ideals and (...) values. Specifically, I argue that if managers were “sages,” the highest moral exemplars and authorities in the Confucian tradition, they would perceive that social rituals alone are often not a contextually intelligent and valued response for the development of intimate communities in the modern workplace. The sage perspective will lead Confucian managers to realize, from their own moral perspective, that they have good reason to balance rites with rights, so long as the adoption is extrinsically valuable and consistent with the Confucian ideal. This article contributes to the debates about Confucianism's compatibility with rights, helps Western human rights scholars better contextualize their arguments in Confucianism-influenced cultures, and contributes to the development of a Confucian or Chinese approach to business ethics.

Hearsay or indirect testimony receives little discussion even today in epistemology, and yet it represents one of the cardinal modes for the transmission of knowledge and for human cognitive development. It suffices to think of school education whereby a student listens to teachers reporting knowledge acquired, often indirectly, from the most varied sources such as text books, newspapers, personal memory, television, etc… Or let us consider the importance of oral tradition in the social and cultural development of civilisations. Or even (...) let us call to mind the learning process of infants who, only thanks to the knowledge learned from others, succeed in learning the language. Finally, with the emerging digital technology, the information gleaned from third parties is influencing the creation of knowledge in a full gamut of fields, in a quasi-comprehensive manner. This leads us to claim that hearsay, despite the reductionist conceptual scheme to which epistemology has confined it in that indirect testimony, is in any case quintessential in the dissemination of knowledge. This work fully expounds upon the basic mechanism of indirect testimonial transmission and provides an epistemologically founded explanation of the cognitive possibilities of hearsay by investigating, in the light of the anti-reductionist paradigm, three mutually connected epistemic properties, namely trust, reputation and coherence, that are key in the epistemic justification of the truth acquired via an indirect testimony.

Shearmur argues for the importance of Popper’s ideas about World 3, and against the idea that they should be re-interpreted in social terms. However, he also argues for the importance of Popper’s ideas about methodological rules—and that these may be given a partially social interpretation. The content of our ideas may in consequence differ from what we take it to be, as a consequence of our institutions and practices operating as methodological rules. He also explores related ideas about the interplay (...) between World 3 and social factors in connection with Darnton’s ideas about the book and work that has built on it, and related issues about the public sphere and the problem of effective deliberative feedback on public policy.

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.

Hempel, Popper, and Kuhn argue that to be scientific is to be testable, to be falsifiable, and most nearly to do normal science, respectively. I argue that to be scientific is largely to be interactive, offering some examples from science to show that the ideas from different fields of science interact with one another. The results of the interactions are that hypotheses become more plausible, new phenomena are explained and predicted, we understand phenomena from a new perspective, and our worldview (...) becomes simpler. I also argue that given that the interactions are impressive features of science, astrology and religion would be regarded as science, provided that there are similar interactions in those enterprises.

The ArgumentScientific tools—measurement and calculation instruments, techniques of inference—straddle the line between the context of discovery and the context of justification. In discovery, new scientific tools suggest new theoretical metaphors and concepts; and in justification, these tool-derived theoretical metaphors and concepts are morelikely to be accepted by the scientific community if the tools are already entrenched in scientific practice.Techniques of statistical inference and hypothesis testing entered American psychology first as tools in the 1940s and 1950s and then as cognitive theories (...) in the 1960s and 1970s. Not only did psychologists resists statistical metaphors of mind prior to the institutionalization of inference techniques in their own practice; the cognitive theories they ultimately developed about “the mind as intuitive statistician” still bear the telltale marks of the practical laboratory context in which the tool was used.

The examples and concepts that Shoemaker cites are rather heterogeneous. Some distinctions need to be drawn. An optimality thesis involves not just an ordering of options, but a value judgment about them. So let us begin by distinguishing minimality from optimality. And the concept of minimality can play a variety of roles, among which I distinguish between extremum descriptions, statements hypothesizing an optimizing process, and methodological recommendations. Finally, I consider how the three categories relate to Shoemaker’s question that “Who is (...) optimizing: the scientist or nature?” . (shrink)

This paper examines the strengths and weaknesses of one of science's most pervasive and flexible metaprinciples;optimalityis used to explain utility maximization in economics, least effort principles in physics, entropy in chemistry, and survival of the fittest in biology. Fermat's principle of least time involves both teleological and causal considerations, two distinct modes of explanation resting on poorly understood psychological primitives. The rationality heuristic in economics provides an example from social science of the potential biases arising from the extreme flexibility of (...) optimality considerations, including selective search for confirming vidence, ex post rationalization, and the confusion of prediction with explanation. Commentators are asked to reflect on the extent to which optimality is an organizing principle of nature, a set of relatively unconnected techniques of science, a normative principle for rational choice and social organization, a metaphysical way of looking at the world, or something else still.

Beyond modularityattempts a synthesis of Fodor's anticonstructivist nativism and Piaget's antinativist constructivism. Contra Fodor, I argue that: (1) the study of cognitive development is essential to cognitive science, (2) the module/central processing dichotomy is too rigid, and (3) the mind does not begin with prespecified modules; rather, development involves a gradual process of “modularization.” Contra Piaget, I argue that: (1) development rarely involves stagelike domain-general change and (2) domainspecific predispositions give development a small but significant kickstart by focusing the infant's (...) attention on proprietary inputs. Development does not stop at efficient learning. A fundamental aspect of human development (“representational redescription”) is the hypothesized process by which information that isina cognitive system becomes progressively explicit knowledgetothat system. Development thus involves two complementary processes of progressive modularization and progressive “explicitation.” Empirical findings on the child as linguist, physicist, mathematician, psychologist, and notator are discussed in support of the theoretical framework. Each chapter concentrates first on the initial state of the infant mind/brain and on subsequent domain-specific learning in infancy and early childhood. It then goes on to explore data on older children's problem solving and theory building, with particular focus on evolving cognitive flexibility. Emphasis is placed throughout on the status of representations underlying different capacities and on the multiple levels at which knowledge is stored and accessible. Finally, consideration is given to the need for more formal developmental models, and a comparison is made between representational redescription and connectionist simulations of development. In conclusion, I consider what is special about human cognition by speculating on the status of representations underlying the structure of behavior in other species. (shrink)

The main claim of this paper is that the method outlined and used in Aristotle’s Ethics is an appropriate and credible one to use in bioethics. Here “appropriate” means that the method is capable of establishing claims and developing concepts in bioethics and “credible” that the method has some plausibility, it is not open to obvious and immediate objection. It begins by suggesting why this claim matters and then gives a brief outline of Aristotle’s method. The main argument is made (...) in three stages. First, it is argued that Aristotelian method is credible because it compares favourably with alternatives. In this section it is shown that Aristotelian method is not vulnerable to criticisms that are made both of methods that give a primary place to moral theory (such as utilitarianism) and those that eschew moral theory (such as casuistry and social science approaches). As such, it compares favourably with these other approaches that are vulnerable to at least some of these criticisms. Second, the appropriateness of Aristotelian method is indicated through outlining how it would deal with a particular case. Finally, it is argued that the success of Aristotle’s philosophy is suggestive of both the credibility and appropriateness of his method. (shrink)

Classical realism is enjoying a renaissance in the study of international relations. It is well known that the analytical and normative international-political thought of early 20th-century classical realists is based on assumptions about human nature. Yet current knowledge of these assumptions remains limited. This article therefore revisits and examines the nature and intellectual roots of the human nature assumptions of three truly consequential classical realists. The analysis shows — similar to the causa Hans J. Morgenthau — that the human nature (...) assumptions of George F. Kennan, Walter Lippmann and E. H. Carr are — to varying degrees — Freudian. Unless this hitherto neglected dimension is recognized, an understanding of their international-political thought and of the political philosophy of realism remains incomplete. Two conclusions are presented. First, current criticism of classical realism’s human nature assumptions is unjustified. Second, any (re-) engagement with classical realism must recognize its human nature baggage. Realist international-political theorizing is necessarily human nature-based international-political theorizing. (shrink)

Mealey's sociopathy model is an exemplar of popular diathesis-stress models. Although such models, when presented in descriptive language, offer the illusion of integrative explanation, their actual scientific value is very limited because they fail to make specific, quantitative, falsifiable predictions. Conceptual and quantitative weaknesses of such diathesis-stress models are discussed and the requirements for useful models are outlined.

Recent evidence that psychopathy is a nonarbitrary population, such that the trait may be categorical rather than continuous, is consistent with Mealey's distinction between primary and secondary psychopaths. Thus, there are likely to be at least two routes to criminality, and psychopathic and nonpsychopathic criminals are likely to respond differently to interventions.

Although Mealey's account provides several interesting hypotheses, her integration across disparate samples renders the value of her explanation for psychopathy ambiguous. Recent evidence on Psychopathy Checklist-identified samples (Hare, 1991) suggests primary emotional and cognitive deficits inconsistent with her model. Whereas high-anxious psychopaths display interpersonal deficits consistent with Mealey's hypotheses, low-anxious psychopaths' deficits appear more sensitive to situational parameters than predicted.

Further understanding at neuroscientific and personality levels should considerably advance our ability to deal with individuals that have strong sociopathic tendencies. An analysis of neurodynamic responses to emotional stimuli will eventually be able to detect sociopathic tendencies of the brain. Such information could be used to enhance the options available to individuals at risk without limiting their personal freedoms.
