BACKGROUND: Reasoning biases have been suggested as risk factors for delusional ideation in both patients and non-clinical individuals. Still, it is unclear how these biases are longitudinally related to delusions in the general population. We hence aimed to investigate longitudinal associations between reasoning biases and delusional ideation in the general population. METHODS: We conducted an online cohort study with 1184 adults from the German and Swiss general population. Participants completed measures on reasoning biases (jumping-to-conclusion bias JTC, liberal acceptance bias LA, (...) bias against disconfirmatory evidence BADE, possibility of being mistaken PM) and delusional ideation at baseline, and delusional ideation 7 to 8 months later. RESULTS: A greater JTC bias was associated with a greater increase in delusional ideation over the following months. This association was better described by a positive quadratic relationship. Neither BADE, LA nor PM were associated with subsequent changes in delusional ideation. CONCLUSIONS: This study suggests that jumping-to-conclusions predicts delusional ideation in the general population but that this association may follow a quadratic trajectory. While no other associations turned significant, future studies with shorter temporal distances may shed further light on the role of reasoning biases as risk factors for delusional ideation in non-clinical samples.

The prisoner 's dilemma game has acquired large literatures in several disciplines. It is surprising, therefore, that a good definition of the game is hard to find. Typically an author relates a story about captured criminals or military rivals, provides a particular payoff matrix and asserts that the PD is characterized, or illustrated, by that matrix. In the few cases in which characterizing conditions are given, the conditions, and the motivations for them, do not always agree with each other or (...) with the paradigm examples elsewhere. In this paper we describe several varieties of PD's. In particular, we suggest there are two distinctions among PD's with philosophical significance, the pure/impure and the utilitarian/nonutilitarian distinctions. In the first section, we explain and characterize the two distinctions. In the second, we discuss an issue of moral philosophy that illustrates the significance of the former. (shrink)

A notable early result of David Makinson establishes that every monotone modal logic can be extended to LI, LV, or LF, and every antitone logic can be extended to LN, LV, or LF, where LI, LN, LV, and LF are logics axiomatized, respectively, by the schemas □α↔α, □α↔¬α, □α↔⊤, and □α↔⊥. We investigate logics that are both monotone and antitone (hereafter amphitone). There are exactly three: LV, LF, and the minimum amphitone logic AM axiomatized by the schema □α→□β. These logics, (...) along with LI, LN, and a wider class of “extensional” logics, bear close affinities to classical propositional logic. Characterizing those affinities reveals differences among several accounts of equivalence between logics. Some results about amphitone logics do not carry over when logics are construed as consequence or generalized (“multiple-conclusion”) consequence relations on languages that may lack some or all of the nonmodal connectives. We close by discussing these divergences and conditions under which our results do carry over. (shrink)

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were—and still are. _The Structure of Scientific Revolutions _is that kind of book. When it was first published in 1962, it was a landmark event in the history and philosophy of science. Fifty (...) years later, it still has many lessons to teach. With _The Structure of Scientific Revolutions, _Kuhn challenged long-standing linear notions of scientific progress, arguing that transformative ideas don’t arise from the day-to-day, gradual process of experimentation and data accumulation but that the revolutions in science, those breakthrough moments that disrupt accepted thinking and offer unanticipated ideas, occur outside of “normal science,” as he called it. Though Kuhn was writing when physics ruled the sciences, his ideas on how scientific revolutions bring order to the anomalies that amass over time in research experiments are still instructive in our biotech age. This new edition of Kuhn’s essential work in the history of science includes an insightful introduction by Ian Hacking, which clarifies terms popularized by Kuhn, including paradigm and incommensurability, and applies Kuhn’s ideas to the science of today. Usefully keyed to the separate sections of the book, Hacking’s introduction provides important background information as well as a contemporary context. Newly designed, with an expanded index, this edition will be eagerly welcomed by the next generation of readers seeking to understand the history of our perspectives on science. (shrink)

The system obtained by adding full propositional quantification to S5 is known to be decidable, while that obtained by doing so for T is known to be recursively intertranslatable with full second-order logic. Recently it was shown that the system with two S5 operators and full propositional quantification is also recursively intertranslatable with second-order logic. This note establishes that the map assigning [1][2]p to \squarep provides a validity and satisfaction preserving translation between the T system and the double S5 system, (...) thus providing an easier proof of the recent result.

Ranging from Joseph Bellamy to Hilary Putnam, and from early New England Divinity Schools to contemporary university philosophy departments, historian Bruce Kuklick recounts the story of the growth of philosophical thinking in the United States. Readers will explore the thought of early American philosphers such as Jonathan Edwards and John Witherspoon and will see how the political ideas of Benjamin Franklin, Thomas Paine and Thomas Jefferson influenced philosophy in colonial America. Kuklick discusses The Transcendental Club (members Henry David Thoreau, Ralph (...) Waldo Emerson) and describes the rise of pragmatism centered on Metaphysical Club of Cambridge (and members William James, Oliver Wendell Holmes, and Charles Peirce). He examines the profound impact Darwinism had on American philosophy and looks at Idealists such as the Kantian Josiah Royce and the Hegelian John Dewey. The book shows how, in the twentieth century, the Nazi conquest of Europe unleashed a flood of European intellectuals onto these shores, including such major thinkers as Theodore Adorno, Erich Fromm, Rudolph Carnap, and Alfred Tarski. Finally, Kuklick examines the contributions of such contemporary philosophers as Sidney Hook and Willard Quine and such books as John Rawl's A Theory of Justice and Herbert Marcuse's One Dimensional Man. Kuklick pulls no punches in portraying the state of American philosophy today and its contested role in the intellectual life of the nation and the world. The range of philosophical thought in our nation's history has been great, from Edwards's Religious Affections to Kuhn's The Structure of Scientific Revolutions, and Bruce Kuklick has captured it all in a book that blends intricate details with sweeping vision.

Transoral laser microsurgery applies to the piecemeal removal of malignant tumours of the upper aerodigestive tract using the CO2 laser under the operating microscope. This method of surgery is being increasingly popularised as a single modality treatment of choice in early laryngeal cancers (T1 and T2) and occasionally in the more advanced forms of the disease (T3 and T4), predomi- nantly within the supraglottis. Thomas Kuhn, the American physicist turned philosopher and historian of science, coined the phrase ‘paradigm shift’ (...) in his groundbreaking book The Structure of Scientific Revolutions. He argued that the arrival of the new and often incompatible idea forms the core of a new paradigm, the birth of an entirely new way of thinking. This article discusses whether Steiner and col- leagues truly brought about a paradigm shift in oncological surgery. By rejecting the principle of en block resection and by replacing it with the belief that not only is it oncologically safe to cut through the substance of the tumour but in doing so one can actually achieve better results, Steiner was able to truly revolutionise the man- agement of laryngeal cancer. Even though within this article the repercussions of his insight are limited to the upper aerodigestive tract oncological surgery, his willingness to question other peoples’ dogma makes his contribution truly a genuine paradigm shift.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

This book is an introduction to and interpretation of the philosophy of language devised by Donald Davidson over the past 25 years. The guiding intuition is that Davidson's work is best understood as an ongoing attempt to purge semantics of theoretical reifications. Seen in this light the recent attack on the notion of language itself emerges as a natural development of his Quinian scepticism towards "meanings" and his rejections of reference-based semantic theories. Linguistic understanding is, for Davidson, essentially dynamic, arising (...) only through a continuous process of theory construction and reconstruction. The result is a conception of semantics in which the notion of interpretation and not the notion of knowing a language is fundamental. In the course of his book Bjorn Ramberg provides a critical discussion of reference-based semantic theories, challenging the standard accounts of the principle of charity and elucidating the notion of radical interpretation. The final chapter on incommensurability ties in with the discussions of Kuhn's work in the philosophy of science and suggests certain links between Davidson's analytic semantics and hermeneutic theory.

A case study of the development of quantum field theory and of S-matrix theory, from their inceptions to the present, is presented. The descriptions of science given by Kuhn and by Lakatos are compared and contrasted as they apply to this case study. The episodes of the developments of these theories are then considered as candidates for competing research programs in Lakatos' methodology of scientific research programs. Lakatos' scheme provides a reasonable overall description and a plausible assessment of the (...) relative value of these two programs in terms of progressive and degenerating problem shifts. Also discussed are the roles of various types of models as they have been used in these areas of theoretical high-energy physics. (shrink)

Puzzle-solving, like several other everyday activities, appears in a more sophisticated and ramified form in the realm of natural science. Improving on Thomas Kuhn's rudimentary account of puzzles in science, this paper formulates logical and functional criteria for the occurrence of scientific puzzles, and examines the two-fold nature of their solutions. Then, with the aid of erotetic logic, puzzle-posing questions are identified, their presuppositional relations to scientific theory and explanations are explored, and a new tool for history of science (...) research is developed.

The received view on the contributions of the physics community to the birth of molecular biology tends to present the physics community as sharing a basic level consensus on how physics should be brought to bear on biology. I argue, however, that a close examination of the views of three leading physicists involved in the birth of molecular biology, Bohr, Delbrück, and Schrödinger, suggests that there existed fundamental disagreements on how physics should be employed to solve problems in biology even (...) within the physics community. In particular, I focus on how these three figures differed sharply in their assessment of the relevance of complementarity, the potential of chemical methods, and the relative importance of classical physics. In addition, I assess and develop Roll-Hansen’s attempt to conceptualize this history in terms of models of scientific change advanced by Kuhn and Lakatos. Though neither model is fully successful in explaining the divergence of views among these three physicists, I argue that the extent and quality of difference in their views help elucidate and extend some themes that are left opaque in Kuhn’s model.

In lieu of an abstract, here is a brief excerpt of the content:116 HISTORY OF PHILOSOPHY Forms not only as objects of contemplation but as patterns of conduct. Presumably the "physicist " is not interested, as physicist, in completing the dialectical journey. So from a moral point of view he rests in opinion, even though his thought may be conversant with Forms. Gully does not like the idea that the philosopher has a privileged method; Plato "gives no proper reason why (...) one particular method or account is privileged" (p. 146).Methods of "collection and division," as developments within the dialectical method, are discussed in the later dialogues, but they never take us to the end of the dialectical journey. Perhaps we should say that the modesty of Socrates in Books VI and VII of the Republic is prophetic. If one is looking for a completed theory of knowledge, one does not find it. Gulley is in agreement with this point, but he feels that if one wants to look for the area in which Plato could have settled on an adequate theory one will find it in the relationship of pure to applied mathematics. He says that Plato develops in his latest thought "a metaphysical theory restricted to the explanation of mathematical knowledge which provides a more satisfactory explanation of the distinction between a priori and empirical knowledge than does the theory of Forms" (p. 187). Yet with a suggestion of surprise he concludes, on Aristotle's testimony, that Plato 2id not "abandon the more general explanation.., which the theory of Forms provided." I 1o not think Gulley wishes to suggest that Plato should have seen the light as Gulley sees it, ~or Gulley conveys the impression of having confronted a puzzling fact. Some readers may be reassured in their efforts to lop off Level IV and commit it to the flames, but the author has presented his case with impartiality.

It is a testimony to the enduring importance of Thomas Kuhn's The Structure of Scientific Revolutions that, 30 years on, its doctrines of normal science and paradigm, incommensurability and revolution continue to challenge metascien tists and stimulate vigorous debate. Critique has mainly come from philosophers and historians; by and large, interested sociologists have embraced Kuhn. Un justifiably so, this article argues, bringing to light a serious difficulty or anom aly in his account of the social side of science. (...) Contrary to what he claims, scientific knowledge is not the achievement of organic communities. It is con structed in trans-epistemic arenas by diverse participants, laypeople, and specialists. Accepting community is a flawed concept in the sociology of science, and in appreciating the major role Kuhn assigned it, the Kuhnian system looks less robust than it did before. (shrink)

The article examines the problem of interpreting normal and revolutionary science in the concept of Thomas Kuhn. It is shown that the “normal science” is the central concept of the Kuhn’s history of science, designed in accordance with the normative definition of science adopted by him. Such a story serves an internal purpose – to justify the special epistemical status of expert knowledge. But there is also an external goal – to establish professional science as an institution with (...) special epistemological status and social function, which is situated in a center of intellectual power and property. Historians are those who are forced to constantly rewrite history – either following the methodology of “rational reconstruction” or responding to the challenges of their time. To be a “conservative” or a “revolutionary” in the history of science is a choice made not only for philosophical reasons, but also under the influence of the general socio-cultural situation of the epoch.

The history of the philosophy of thought experiments has touched on the work of Kuhn, Popper, Duhem, Mach, Lakatos, and other big names of the 20th century, but so far, almost nothing has been written about Paul Feyerabend. His most influential work was Against Method, 8 chapters of which concern a case study of Galileo with a specific focus on Galileo’s thought experiments. In addition, the later Feyerabend was very interested in what might be called the epistemology of drama, (...) including stories and myths. This paper brings these different aspects of Feyerabend’s work together in an attempt to present what might have been his considered views on scientific thought experiments. I conclude by contrasting Feyerabend’s ideas with two modern currents in the debate surrounding thought experiments: 1) the claim that the epistemology of thought experiments is just the epistemology of deductive or inductive arguments, and 2) the claim that the specifically narrative quality of thought experiments must be taken into account if we want a complete epistemology of thought experiments.

In his book Radical Evolution: The Promise and Peril of Enhancing Our Minds, Our Bodies—and What It Means to Be Human (2005), author-journalist Joel Garreau identifies four technologies whose synergistic activity may transform humankind into a state transcending present human nature: genetic, robotic, information, and nano (GRIN) technologies. If the GRIN technologies follow Moore's Law, as information technology has done for the past four decades, Homo sapiens and human society may be unimaginably different before the middle of this century. But (...) among scientists, futurists, and other pundits there is no agreement on the nature and ramifications of this transformation. Based on dozens of interviews, Garreau sees three possible scenarios for our species. The Heaven Scenario foresees enhanced bodies and minds in a disease-free world, perhaps even immortality; the Hell Scenario warns of losing our identity as a biological entity and perhaps the demise of liberal democracy; the Prevail Scenario predicts that we will muddle through the GRIN technology revolution basically intact, as we have prevailed during past technological upheavals. In this review, these scenarios are examined in the context of Kuhn's “normal” versus “extraordinary” science and in the context of current understanding about gene function. (shrink)

Recent work on Imre Lakatos’s missing Hungarian dissertation on the historical sociology of science sheds new light on his mature philosophy of science. Remembered primarily as an “internalist” defender of the autonomy of science, and a Cold Warrior in poli­tics, commentators have mistaken his contribution as primarily a rearguard action against the followers of Thomas Kuhn and the “externalists” influenced by Boris Hessen. It comes as a surprise, then, to find that he developed and retained a fully general soci­ology (...) of scientific knowledge, with Marxist roots that articulated Lenin’s “inexhaustible atom.” He carried forward this emphasis on the fallible, changing, and incomplete nature of our engagement with the natural world by a dialectical account of how research programs advance and recede historically. In his effort to develop a synthesis of Popper and Kuhn, and via his engagement with Paul Feyerabend, he continued to develop a distinctly dialectical ap­proach to science. (shrink)

The question, how is profound intellectual disagreement possible, even when addressed toward the paradigmatically reasonable activity of scientific communication, has generated a number of puzzling responses. On a response attributed to Thomas S. Kuhn, some episodes in the history of science don't allow for meaningful disagreement. In such situations, the adversaries talk at cross purposes until one side is either "converted" or dies off. ;This skeptical prospect has also been considered by those who study the differences between natural languages, (...) and the misunderstandings which punctuate a child's first language acquisition. I investigate theories of concepts in search of one capable of illuminating the apparent gaps in communication between scientists, between speakers of different languages, and between infants and adults. I begin by showing that the antipsychologist efforts of post-Fregean philosophers of language, in particular those built on a causal theory of reference, fail to explain either how communication is possible when it is, or why it isn't otherwise. Nor does recourse to a principle of charity or humanity help them in this regard. I conclude that such attempts can't ground an account of communication. ;I argue that an account of concept learning drawn in part from recent work in developmental psychology can explain both the possibility of serious disagreement, as well as the possibility of overcoming it reasonably. I urge that the revival of psychologism in the philosophy of language follows. Semantic psychologism is semantics informed by empirical psychology, not by the phenomenology Frege attacked. I explore the consequences of this doctrine for the philosophy and history of science. These include a rejection of the common philosophical assumption that all meaningful communication can be reduced to a form of translation, and renewed emphasis on the importance of analogy in communication. ;Finally, I apply this new semantic psychologism toward the historical interpretation of science. If the program is right, it should provide insight into the communicative dimensions of important episodes in the history of science. While a full exploration of this historical method lies beyond the scope of my thesis, two preliminary case studies indicate its fruitfulness. (shrink)

Nuestro siglo avanza, y una cierta perspectiva de él, o por lo menos de su inicio, empieza a perfilarse. En el panorama reflexivo ha ido tomando fuerza un movimiento que podría pretenderse como la emblemática filosofía del s. XXI: nos referimos al neorrealismo. El presente trabajo ensaya un acercamiento a tal movimiento de la mano de uno de sus afamados representantes, Markus Gabriel; podemos aprovechar el examen de algunas de las tesis del autor germano para hacernos una idea de por (...) dónde discurre el caminar de nuestra fonda reflexión, en este caso en el marco del longevo debate realismo vs. idealismo (o metafísica vs. constructivismo, como se estime). Tal lid podría entenderse de raigambre ontológica, pero nos hemos ido dado cuenta de la fundamental co-implicación entre ser y saber. De esta suerte, a partir de la analítica de Gabriel a propósito de lo existente y el mundo se inferirán consecuencias (o tal vez sea en dirección contraria) sobre modos, medios, elementos y condiciones de tal saber, destacándose la posibilidad y oportunidad de manejar cosmovisiones, una cuestión ya planteada en autores como Dilthey, Heidegger, Foucault o Kuhn. Todo ello nos abre la vía para reflexionar sobre la propia reflexión, recordándosenos que lo filosófico, por lo menos en nuestra civilización occidental, ha llamado al diálogo desde diferentes puntos de vista, haciendo hincapié en el compromiso y practicidad de la filosofía en sí misma, capaz de coadyuvar en la preservación de ese tesoro de nuestra cultura que es su multiplicidad y poliedrismo.

T. Kuhn’s theory of scientific revolutions has repeatedly been the subject of criticism. It is important to note that Kuhn pays very limited attention to the phenomenon of the scientific revolution itself, comparing the revolution either with a religious conversion or with a gestalt switch. Such comparisons, however, are very superficial. This paper outlines a new understanding of the scientific revolution as a result of the resonance of the intellectual trends of the early modern period. It was the (...) quasi-simultaneous action of various factors that led to revolutionary changes in natural philosophy, which, in turn, gave rise to the actual scientific revolution. In addition, the article shows that the Copernican Revolution cannot be described within the model of scientific revolution developed by T. Kuhn. Ptolemy’s theory was mathematically constructed so that it could not make inaccurate predictions of planetary motion, because – as we are now clear – the function characterizing the trajectory of planetary motion was actually represented as a Fourier series. The Copernican revolution was not a Kuhn-type scientific revolution, nor was it caused by the empirical failures of Ptolemaic astronomy. Events unfolded according to a different scheme. Copernicus set out to carry out the principle of the uniform circular motion of the planets more consistently than had been done in Ptolemy’s theory, at the same time presenting to this theory those requirements of an aesthetic and methodological order, which the cognitively fragmented system of Ptolemy, for all its flexibility, could not satisfy and, by the conditions of its creation, could not satisfy. In addition, the article shows that Copernicus, in constructing his heliocentric theory, was essentially seeking answers to the challenges that Alberti’s artificial perspective and Nicholas of Cusa’s theological speculation posed to the visual experience in the sixteenth century.

The uniqueness of logic is upheld and contrasted with twenty roles of a wider responsive order that includes us and our procedures. Empirical responses are precise, but different in different approaches. Procedures and findings are independent of (not separable from) their concepts. Two-way feedback obviates a top-down derivation of findings from assumptions, hypotheses, history, or language. The postmodern problems of interpretation, conditions of appearances and relativism involve the ancient error of making perception the model-instance of experience. Instead, bodily interaction functions (...) in language and precedes perception and interpretation. Logic, space time locations and individuated referents involve positional relations derived from comparing. Beyond Kuhn, Feyerabend, Newton and Einstein, if we can give interaction priority over comparing, the responsive objectivity of both can be upheld. A new empiricism, neither naive nor constructivist, uses the words order, explication, truth, and exactly to build on Wittgenstein and on Dilthey's hermeneutic. Natural language is metaphor-like, originally crossed. Logic must ignore its assumptions. It must render everything as a machine and drop humans and animals out. A new discipline is proposed, to move between the logical and the responsive orders, to deal with the machine/human interface and the social uses of science such as bioengineering. (shrink)

Ideas used in the philosophy of science to describe the development of science (T. Kuhn, V. Stepin, K. Hübner) are analyzed in a context of their adaptation for educational purposes. It is shown that the most appropriate approach considers the science as a unique complex self-organizing system. This approach makes it possible to integrate any fruitful ideas from different models.

Point-of-care testing (POCT) is a sensitive, specific and rapid form of testing for the presence of HIV antibodies. Post-exposure prophylaxis for HIV infection can reduce seroconversion rates by up to 80%. Needlestick injuries are the second commonest cause of occupational injury in the NHS and 20% of these occur during operations. In the NHS, in order to protect staff and patients from the risk of bloodborne viruses such as HIV, it is mandatory to report such injuries; however, numerous studies have (...) shown that many groups, particularly doctors, are reluctant to do so. This article outlines the arguments for and against the introduction of preoperatively seeking consent from patients to have their blood tested for HIV via POCT in order to improve the reporting rates of needlestick injuries incurred during surgery and to protect staff from infection.
