In this book, I will discuss three main topics: the roots and aims of scientific knowledge, scientific knowledge in society, and science and values I understand scientific knowledge as being a planned and continuous production of the general and common knowledge of scientific communities. I begin my discussion with a brief analysis of the main differences between sciences, on the one hand, and everyday experience, philosophies, religions, and ideologies, on the other. I define the concept of science as a set (...) of family resemblances (in Wittgenstein's sense). The sciences can be distinguished along three lines, in terms of the difference between empirical and non-empirical sciences, differences in degrees of theoretical and methodological structure among individual sciences and scientific disciplines. Scientific knowledge is based upon some grounds, paradigmatic knowledge bases. Scientific knowledge is founded on a unified paradigmatic knowledge base. The latter includes fundamental theories, basic facts, generally accepted empirical regularities (laws), scientific research methods, scientific explanations, and established relations to other sciences. Scientific knowledge in general is defined well in classical terms by the definition that knowledge is a true and rationally-justified belief. In this connection, scientific truth is relative, depending on the given paradigmatic knowledge base and on the precision and accessibility of the measurements and observations involved. In the book's first part, I consider the production and testing of scientific hypotheses, scientific explanations, the structure of scientific theories, and the problem of scientific realism. I consider explanation an integral part of a wider nexus of heuristic and theoretical activities in science like giving reasons, understanding, clarification, and founding. Continuous production of scientific explanations is a necessary condition for the systematic reproduction of scientific knowledge. Accordingly, it does not suffice to describe them in terms of the logical structure of the arguments on which they are based, but rather, scientific explanations ought to be given complete with an epistemic and pragmatic context of the explanation. I consider especially deductive-nomological, inductive-statistical, dispositional, teleological-functional, and genetic explanations. I emphasize the ever-increasing importance of explanations by analogy and by model. Orthogonal to these distinctions lies the distinction between causal and epistemic explanation. Epistemic explanations relate scientific discoveries to epistemic progress, and causal explanations are these epistemic explanations that relate scientific discoveries to reality too. Causal explanations inform us that certain changes occur in the world as agents of other changes, or rather, that certain changes are real consequences of other changes. Thus, by having explanations of causes, we can intervene in the world to induce by design certain changes in some course of phenomena. I consider scientific theories as logically and epistemically ordered wholeness of scientific knowledge in a realm of research that enables us to construct useful models of reality. After the discussion of different 'statement' views on theories and different interpretations of the theory-experience relation, I introduce the 'model' theoretical (non-statement) views on theories, especially the structural theory of science. The model views on theories transcend the realism-antirealism dualism by introducing models between theory and reality. Therefore, the question of scientific realism is not merely whether and, if so, which element(s), of scientific theories represent reality, but rather which conditions suffice to infer from a theory that one of its models truly expresses reality. In other words, under which conditions do models of a theory represent models of reality? Generally, models are just as much images of reality in a theory as they are images of a theory in reality. The actual problem of scientific realism doesn't originate in the observable-unobservable distinction (even if this distinction is otherwise theoretically loaded), but rather in ontological quandaries, of the sort especially encountered in modern physical theories such as quantum mechanics, relativity theory, and cosmological theories, although they are known to arise in other sciences as well. Scientific theories may be real, even if they describe nothing about the world. However, such theories can be given this status only if their formal, mathematical postulates exhibit some formal homology between reality and mathematical forms. The very fact that it is possible to describe reality with the help of mathematics even in cases, where every (representational, conceptual) language and thought fall short, would indicate that even mathematics itself is, in some sense, a part of reality, although 'outside' of the empirical world. It follows we have to distinguish the non-empirical reality and the empirical world. Formal objectivity and non-arbitrariness of theories do not emerge from either our language or thoughts, or from the world of facts, causes, and effects, but rather from non-empirical reality, which frames the world as some kind of objective transcendental condition for the possibility of the existence of the world, thoughts, and language. In the second part of the book, I consider the incorporation of scientific work and scientific knowledge into modern society and its relations to values and ethics. Production of scientific knowledge goes on as a parallel distributed process of a special kind of social (shared) cognition. The central part of this cognition is the presentation of parts of the world by scientific (theoretical) models which are warranted by the shared and public practice of justification, and in reflective acting in the world as it would. I consider various formal concepts of collective propositional knowledge (distributed, mutual, common knowledge). Scientific knowledge is an achievement to be ascribed to a scientific community or, indirectly, to all those who apply or expand it, rather than to individuals per se. It presents the continuous and partially planned production of non-trivial common knowledge of the research communities in modern societies. However, besides common knowledge, shared dispositional knowledge (knowledge how of scientific teams) and shared knowledge by acquiring (knowledge of fundamental similarities and differences in scientific teams) are parts of the real body of scientific knowledge. Scientific common knowledge implies the projection into idealized universal knowledge of all real or potentially rational and well-informed individuals. The respect of scientific knowledge thus presents the norm of rationality. Science as the intensively shared and socially distributed kind of cognition enters into modern society as a special kind of work (general work), as a productive force (social invention drive), and as a form of capital (human, social, cultural, informational, etc.). However any of these categories can adequately represent the socio-economical role of science in modern societies, and we are still waiting for a more adequate general concept that would theoretically cover the 'scientification' of modern societies. My thesis is that the most important general effect of scientification is (and will be) the growth of social processes that structurally resemble parallel distributed shared social cognition of science, and not so much the rise of the use of scientific knowledge and scientifically based information in all kinds of production. Scientification of modern societies inevitably includes a much stronger need for moral and social responsibility of scientists for their work and its effects in their local society and the global world. This need comes in contradiction with the quite large accepted idea (and even the 'norm') on value-free research. I discuss to some degree different arguments for the absence of non-epistemic values and ethical reasoning from science and find them non-convincing. The sound idea of value-free research lies in the need for the absence of categorical value statements from scientific explanations and theoretical deductions. Values and ethical judgment have, and sometimes they even have to play an important role in another part of research and its application in science or outside it. Not the value-loudness of research is a danger for science but its blind, non-reflective use. It leads to the ideologization and politicization of science. A similar danger lies in the purely value-neutrality of research. It leads to the instrumentalization of science to the technical or bureaucratic means for 'any' aims. (shrink)

These two small works are a good supplement to Rescher’s recent trilogy. Whereas the systems-theoretic approach is employed in Methodological Pragmatism in dealing with the problem of the legitimation of claims to factual knowledge or cognitive rationality, Dialectics deals with the argumentation aspect of thesis-introduction rather than the logical aspect of thesis-derivation. Although some key notions such as the idea of burden of proof and presumption have been stated in the former work, what is offered here is a (...) systematic discussion of a disputational model of inquiry. The principal aims are "to exhibit the sociocommunal roots of the foundations of rationality, to provide an instrument for the critique of scepticism implicit in the cognitive solipsism of the Cartesian approach, and to illuminate the communal and controversy-oriented aspects of rational argumentation and inquiry—scientific inquiry in particular." Again, Rescher limits his discussion to "the probative mechanism in the factual domain." This book, if it were not for its price, should be a good supplement to a course in "informal" logic which focuses on argumentation rather than on mere evaluation of arguments. Plausible Reasoning provides the mechanism for evaluation of plausibility claims as distinct from probabilistic ones. The basic differences between these two types of claims are clearly discussed. "Plausibility is essentially a classificatory concept which ranks theses in terms of the standing and solidity of their cognitive basis. Plausibility grades theses by an external or extrinsic standard of the hierarchical nature of their supporting bases. It classifies propositions by the status of the evidential sources or validating principles that vouch for them. Probability weighs alternatives and evaluates theses by this relative contentual weight of the supporting considerations."—A.S.C. (shrink)

This paper describes a novel perspective on the foundations of mathematics: how mathematics may be seen to be largely about “information compression via the matching and unification of patterns”. That is itself a novel approach to IC, couched in terms of nonmathematical primitives, as is necessary in any investigation of the foundations of mathematics. This new perspective on the foundations of mathematics reflects the facts that mathematics is almost exclusively the product of human brains, and has been developed, as (...) an aid to human thinking, mathematics is likely to be consonant with much evidence for the importance of IC in human learning, perception, and cognition. This perspective on the foundations of mathematics has grown out of a long-term programme of research developing the SP Theory of Intelligence and its realization in the SP Computer Model, a system in which a generalised version of ICMUP—the powerful concept of SP-multiple-alignment—plays a central role. This paper shows with an example how mathematics, without any special provision, may achieve compression of information. Then, it describes examples showing how variants of ICMUP may be seen in widely used structures and operations in mathematics. Examples are also given to show how several aspects of the mathematics-related disciplines of logic and computing may be understood as ICMUP. Also discussed is the intimate relation between IC and concepts of probability, with arguments that there are advantages in approaching AI, cognitive science, and concepts of probability via ICMUP. Also discussed is how the close relation between IC and concepts of probability relates to the established view that some parts of mathematics are intrinsically probabilistic, and how that latter view may be reconciled with the all-or-nothing, “exact,” forms of calculation or inference that are familiar in mathematics and logic. There are many potential benefits and applications of the mathematics-as-IC perspective. (shrink)

There are a number of different species concepts currently in use. The variety results from differing desiderata and practices of taxonomists, ecologists and evolutionary theorists. Recently, arguments have been presented for pluralism about species. I believe this is unsatisfactory, however, because of the central role of species in biological theory. Taking the line that species are individuals, I ask what might individuate them. In other work I have argued that dynamical systems are individuated by their cohesion. I present here a (...) version of a cohesion concept of species that accounts for the advantages of other species concepts, and is open-ended enough to accommodate additions to or changes in biological theory. On my account biological forces combine like Newtonian forces, to work on a common locus. Just as we might have an electromagnetic system, we might have an ecological species, if the dominant source of cohesion is ecology, but there is no certainty that biological species will divide up into elegant single principle types anymore than there is for physical systems.

[Edited from Conclusion section:] We have looked at various challenging issues to do with getting connectionism to cope with high-level cognitive activities such a reasoning and natural language understanding. The issues are to do with various facets of generalization that are not commonly noted. We have been concerned in particular with the special forms these issues take in the arena of propositional attitude processing. The main problems we have looked at are: (1) The need to construct explicit representations of generalizations, (...) not just generalize correctly to individual cases; (2) The need to be able to match two or more complex short-term information structures, to enable rapid generalization from recent examples rather than from long-term memories; (3) The need to represent and reason with anomalous combinations of concepts; (4) The need to perform embedded reasoning. This presents special problems for systems using non-concatenative representations (as in mainstream connectionist approaches). We also touched on vague quantification in attitude report complements. Neither this topic nor that of analogies between short-term structures (point 2) has been adequately addressed in the symbolic framework, let alone in connectionism. -/- The opportunities and problems covered are put forward as things worth being optimistic about or pessimistic about, respectively. They are not put forward as decisive arguments for or against connectionism. The hope is that this chapter contributes to a greater understanding of the connectionist/symbolist gap by presenting some unusual issues and by throwing new light on some well known ones. (shrink)

. Artificial Intelligence (AI) has long dealt with the issue of finding a suitable formalization for commonsense reasoning. Defeasible argumentation has proven to be a successful approach in many respects, proving to be a confluence point for many alternative logical frameworks. Different formalisms have been developed, most of them sharing the common notions of argument and warrant. In defeasible argumentation, an argument is a tentative (defeasible) proof for reaching a conclusion. An argument is warranted when it ultimately (...) prevails over other conflicting arguments. In this context, defeasible consequence relationships for modelling argument and warrant as well as their logical properties have gained particular attention. This article analyzes two non-monotonic inference operators Carg and Cwar intended for modelling argument construction and dialectical analysis (warrant), respectively. As a basis for such analysis we will use the LDSar framework, a unifying approach to computational models of argument using Labelled Deductive Systems (LDS). In the context of this logical framework, we show how labels can be used to represent arguments as well as argument trees, facilitating the definition and study of non-monotonic inference operators, whose associated logical properties are studied and contrasted. We contend that this analysis provides useful comparison criteria that can be extended and applied to other argumentation frameworks. (shrink)

My aim here is (1) to argue that the usual argument for thinking dysfunction has no place in a dispositionalist approach to functions is deeply flawed and (2) to develop a positive account of the explanatory role dysfunction attributions play in dispositionalist-style functional analysis. I will also argue that while my account undermines one common motivation for preferring an etiological over a dispositionalist approach, perhaps more interestingly, it also blurs the boundary between the two and opens a path (...) to unifying them.

Causal inference plays a central role in behavioral science. Historically, behavioral science methodologies have typically sought to infer a single causal relation. Each of the major approaches to causal inference in the behavioral sciences follows this pattern. Nonetheless, such approaches sometimes differ in the causal relation that they infer. Incremental causal inference offers an alternative to this conceptualization of causal inference that divides the inference into a series of incremental steps. Different steps infer different causal (...) relations. Incremental causal inference is consistent with both causal pluralism and anti-pluralism. However, anti-pluralism places greater constraints the possible topology of sequential inferences. Arguments against causal inference include questioning consistency with causation as an explanatory principle, charging undue complexity, and questioning the need for it. Arguments in favor of incremental inference include better explanation of diverse causal inferences in behavioral science, tailored causal inference, and more detailed and explicit description of causal inference. Incremental causal inference offers a viable and potentially fruitful alternative to approaches limited to a single causal relation. (shrink)

Argumentation theory is a distinctly multidisciplinary field of inquiry. It draws its data, assumptions, and methods from disciplines as disparate as formal logic and discourse analysis, linguistics and forensic science, philosophy and psychology, political science and education, sociology and law, and rhetoric and artificial intelligence. This presents the growing group of interested scholars and students with a problem of access, since it is even for those active in the field not common to have acquired a familiarity with relevant aspects (...) of each discipline that enters into this multidisciplinary matrix. This book offers its readers a unique comprehensive survey of the various theoretical contributions which have been made to the study of argumentation. It discusses the historical works that provide the background to the field and all major approaches and trends in contemporary research. Argument has been the subject of systematic inquiry for twenty-five hundred years. It has been graced with theories, such as formal logic or the legal theory of evidence, that have acquired a more or less settled provenance with regard to specific issues. But there has been nothing to date that qualifies as a unified general theory of argumentation, in all its richness and complexity. This being so, the argumentation theorist must have access to materials and methods that lie beyond his or her "home" subject. It is precisely on this account that this volume is offered to all the constituent research communities and their students. Apart from the historical sections, each chapter provides an economical introduction to the problems and methods that characterize a given part of the contemporary research program. Because the chapters are self-contained, they can be consulted in the order of a reader's interests or research requirements. But there is value in reading the work in its entirety. Jointly authored by the very people whose research has done much to define the current state of argumentation theory and to point the way toward more general and unified future treatments, this book is an impressively authoritative contribution to the field.

In order to make scientific results relevant to practical decision making, it is often necessary to transfer a result obtained in one set of circumstances—an animal model, a computer simulation, an economic experiment—to another that may differ in relevant respects—for example, to humans, the global climate, or an auction. Such inferences, which we can call extrapolations, are a type of argument by analogy. This essay sketches a new approach to analogical inference that utilizes chain graphs, which resemble directed (...) acyclic graphs (DAGs) except in allowing that nodes may be connected by lines as well as arrows. This chain graph approach generalizes the account of extrapolation I provided in my (2008) book and leads to new insights that integrate the contributions of the other participants of this symposium. More specifically, this approach explicates the role of “fingerprints,” or distinctive markers, as a strategy for avoiding an underdetermination problem having to do with spurious analogies. Moreover, it shows how the extrapolator’s circle, one of the central challenges for extrapolation highlighted in my book, is closely tied to distinctive markers and the Markov condition as it applies to chain graphs. Finally, the approach suggests additional ways in which investigations of a model can provide information about a target that are illustrated by examples concerning nanomaterials in sunscreens and Wendy Parker’s discussion of fingerprints in climate science.

The exhaustion particles of the Yi languages are sentence-end morphemes with a surprising wealth of possible interpretations. With gradeable states they convey the meaning of superlative, with accomplishments they function as completive particle, and in ungradeable states, activities or achievements they act as all particles, i.e. as universal non-distributive quantifiers, on the first argument. A unified account of the all -, completive - and superlative -meanings is proposed. It is argued that all three notions basically divide their respective domain (...) into three types: a singular domain type, a quantized domain type and a homogeneous domain type. For events there is also a fourth domain type, the bounded domain type, which does not have an analogy with objects and states. Object-denotations Event-denotations State-denotations Singular Individual OD Punctual ED Ungradeable SD Quantized Quantized OD Quantized ED State with quantized comparison class Bounded — Bounded ED — Homogeneous Homogeneous OD Homogeneous ED State with homogeneous comparison class The all -, the completive - and the superlative -meanings of the exhaustion particles have in common that they are incompatible with entities from the singular domain type, pragmatically implausible with entities from the homogeneous domain type, and compatible with entities from the quantized domain type.

There are several interpretations of the argument structure of Darwin's Origin of Species, representing Covering-Law, Inference-to-the-Best-Explanation, and (more recently) Semantic models. I argue that while all three types of interpretation enjoy some textual support, none succeeds in capturing the overall strategy of the Origin, consistent with Darwin's claim that it is 'one long argument'. I provide detailed criticisms of all three current models, and then offer an alternative interpretation based on the view that there are three main argument strategies (...) in the Origin, all supporting the 'causal efficacy' of Darwin's theory. This interpretation provides both a more unified treatment of the text, and some important implications concerning the relation between general philosophical models of scientific theory support and specific historical cases.

As a learning tool, argument and decision maps enable students to hone their interpretive and analytical skills. This paper illustrates one effective approach to teaching the diagrammat­ic conventions used in a powerful decision and argument mapping methodology. The twenty example maps included begin with a configuration illustrating one reason offered in support of a conclusion, and build to highly complex maps illustrating the analyses of real world decisions as recorded in interviews and official documents. Using their interpretive and analytical (...) skills, and the simple conventions taught and illustrated here, students and researchers are able to build and to refine maps that show simple arguments, lines of reasoning, unspoken but implicit as­sumptions, pro and con argumentation, individual and group decision making, the influences of reactive cognitive heuristics on decision making, the use of various familiar valid and fallacious inference patterns, and the bolstering phenomenon associated with the use of multiple arguments in support of a given option.

The Handbook of the Logic of Argument and Inference is an authoritative reference work in a single volume, designed for the attention of senior undergraduates, graduate students and researchers in all the leading research areas concerned with the logic of practical argument and inference. After an introductory chapter, the role of standard logics is surveyed in two chapters. These chapters can serve as a mini-course for interested readers, in deductive and inductive logic, or as a refresher. Then follow (...) two chapters of criticism; one the internal critique and the other the empirical critique. The first deals with objections to standard logics (as theories of argument and inference) arising from the research programme in philosophical logic. The second canvasses criticisms arising from work in cognitive and experimental psychology. The next five chapters deal with developments in dialogue logic, interrogative logic, informal logic, probability logic and artificial intelligence. The last chapter surveys formal approaches to practical reasoning and anticipates possible future developments. Taken as a whole the Handbook is a single-volume indication of the present state of the logic of argument and inference at its conceptual and theoretical best. Future editions will periodically incorporate significant new developments. (shrink)

This paper studies a fundamental mechanism by which conflicts between arguments are drawn from sentiments regarding acceptability of the arguments. Given sets of arguments, an inverse abstract argumentation problem seeks attack relations between arguments such that acceptability semantics interprets each argument in the sets of arguments as being acceptable in each of the attack relations. It is an inverse problem of the traditional problem we refer to as the forward abstract argumentation problem. Given an attack relation, the forward (...) abstract argumentation problem seeks sets of arguments such that acceptability semantics interprets each argument in the sets of arguments as being acceptable in the attack relation. We give a probabilistic model of argumentation-theoretic inference. It is a generative model formalising the process by which acceptability semantics interprets acceptability of arguments in a given attack relation. We show that it gives a broad view of solutions to the forward and inverse abstract argumentation problems. Specifically, solutions to the inverse and forward abstract argumentation problems are shown to be equivalent to a maximum likelihood estimate and maximum likelihood prediction, respectively, which are both available with the generative model. In addition, they are shown to be special cases of the posterior distribution and the evidence, respectively, which are both obtained by probabilistic inference on the generative model. We report an experiment result and application example of the generative model in the inverse problems. (shrink)

Although Hume’s critique of the design argument is a powerful non-inductive meta-argument, the main line of critical reasoning is not analogical but rather a complex meta-argument. It consists of two parts, one interpretive, the other evaluative. The critical meta-argument advances twelve criticisms: that the design argument is weak because two of its three premises are justified by inadequate subarguments; because its main inference embodies four flaws; and because the conclusion is in itself problematic for four reasons. Such complexity is (...) quite manageable in a meta-argumentation approach. (shrink)

Leading East Asian Buddhist thinkers of the seventh century compared, analyzed, and finalized seminal epistemological and soteriological issues that had been under discussion in India and East Asia for centuries. Among the many doctrinal issues that came to the fore was the relationship between the Tathagatagarbha understanding of the human psyche and the view of basic karmic indeterminacy articulated by the new stream of Indian Yogacara introduced through the translations and writings of Xuanzang and his disciples. The great Silla scholiast (...) Wonhyo, although geographically located on the periphery in the Korean peninsula, was very much at the center of the intense discussion and debate that occurred on these topics. Through the force of his writings, he became one of the most influential figures in resolving doctrinal discrepancies for East Asian Buddhism. Although many of Wonhyo’s writings are lost, through his extant work we are able to get a solid glimpse of his profound and learned insights on the nature and function of the human mind. We can also clearly see his hermeneutical approaches and methods of argumentation, which are derived from apophatic Madhyamika analysis, the newly introduced Buddhist logic, as well as various indigenous East Asian approaches. This volume includes four of Wonhyo’s works that are especially revelatory of his treatment of the complex flow of ideas in his generation: System of the Two Hindrances, Treatise on the Ten Ways of Resolving Controversies, Commentary on the Discrimination between the Middle and the Extremes, and the Critical Discussion on Inference.

Salutary reading for all philosophers, and not only for inductive logicians, philosophers of science and law, this important book presents an elaborate theory of inductive reasoning whose substantive features are as strikingly original as the approach is rare. First, the theory is based on concrete, real, actual, and significant instances of inductive reasoning, e.g., Karl von Frisch’s work on bees; that is, though its aim is genuinely theoretical in the sense that it engages in the proper amounts of idealization, (...) abstraction, systematization, precision, and rigor, it never loses sight of the fact that "theories in the philosophy of science, like theories in science itself, have to face up to the challenge of appropriately accredited experience within their appointed domains". Second, a central subject matter being analyzed is legal reasoning, that is, the types of proofs and arguments used by juries, judges, and lawyers in the Anglo-American system of jurisprudence, where criminal charges have to be proved beyond reasonable doubt and civil cases have to be argued on the balance of probability. Thus, in effect, Cohen’s synthesis of juridical and of scientific reasoning is an admirable example of the bridging of two "cultures." Third, and most importantly, the concept of "inductive probability," in terms of which Cohen makes sense out of his subject matter, is incommensurable with that of "mathematical probability," namely the classical calculus of chance according to which probability is measurable, additive, transitive, and obeys a multiplicational principle for conjunction and a complementational one for negation. This is not to say that "inductive probability" is a hazy, mysterious, or unstructured concept, and Cohen goes to great lengths to show that it is ordinal, modal, and formally analyzable; what it does mean is that essential types of reasoning in science and in law involve probable inferences whose probabilities are nonquantitative. Hence, though Cohen does not stress the qualitative nature of inductive probability, his book will be welcome by those who conceive of philosophy as scientia qualitatum. Specific conclusions reached by Cohen are that, in general, probability may be conceived as degree of provability, that differences in proof-rules generate different special cases of probability, that inductive probability may be viewed as the special case where the proof-rules are incomplete, that inductive probability is to inductive support as deducibility is to logical truth, and that some recent epistemological scepticism may be refuted by Cohen’s inductive logic. Finally, he sees himself in the British inductivist tradition, interpreting his predecessors as groping toward a logic of inductive support and probability rather than a methodology of discovery: from Bacon he develops the notion of eliminative induction but rejects that of induction by enumeration; Mill’s canons are analyzed as special cases of Cohen’s own "method of relevant variables," except for the method of residues, which is rejected as invalid ; he takes his critique of mathematical probability as a vindication of Hume’s thesis that "probability or reasoning from conjecture may be divided into two kinds, viz., that which is founded on chance and that which arises from causes" ; Whewell’s consilience of induction is justified ; and from Keynes, he develops the notion of the "weight" of evidence but rejects his mathematicist approach.—M.

This paper compares current ways of modeling the inferential structure of practical reasoning arguments, and proposes a new approach in which it is regarded in a modular way. Practical reasoning is not simply seen as reasoning from a goal and a means to an action using the basic argumentation scheme. Instead, it is conceived as a complex structure of classificatory, evaluative, and practical inferences, which is formalized as a cluster of three types of distinct and interlocked argumentation (...) schemes. Using two real examples, we show how applying the three types of schemes to a cluster of practical argumentation allows an argument analyst to reconstruct the tacit premises presupposed and evaluate the argumentative reasoning steps involved. This approach will be shown to overcome the limitations of the existing models of practical reasoning arguments within the BDI and commitment theoretical frameworks, providing a useful tool for discourse analysis and other disciplines. In particular, applying this method brings to light the crucial role of classification in practical argumentation, showing how the ordering of values and preferences is only one of the possible areas of deep disagreement.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Unmodern Philosophy and Modern Philosophy by John DeweyCharles A. HobbsJohn Dewey. Unmodern Philosophy and Modern Philosophy. Carbondale and Edwardsville: Southern Illinois University Press, 2012, 351 pp., index.John Dewey’s latest publication marks a watershed moment for scholarship in American philosophy, and, in addition to Dewey himself, we have editor Phillip Deen to thank for discovering it (among the Dewey papers in Special Collections at Morris Library of Southern Illinois (...) University) and editing it. We see Dewey late in life (early 1940s) engaged mainly in a critique of the modern, ancient, and (fragmentarily) medieval philosophical periods, which Dewey argues, are eras not nearly as distinct as traditional understanding admits. In the Introduction, Deen helpfully explains how we are now bequeathed incomplete but in most [End Page 122] cases quite robust chapter drafts that amount to another substantial work by Dewey. While published by Southern Illinois University Press, this volume is not itself part of The Collected Works of John Dewey. Still, the careful editing (of what are actually a number of manuscripts) is comparable in its excellence. There is also a well-done Index.The scope is twofold: retrospective and prospective. Chapters one through seven trace the development of so-called modern philosophy along with its central epistemological problem, with the aim being to demonstrate how thoroughly “unmodern” such philosophy has been. Then, chapters eight through fourteen constitute a genuinely modern approach that naturalistically and functionally undercuts the epistemic problem of subject/object and points to a revolution in the process of knowing.We turn to the retrospective, beginning in the first chapter with the acknowledgement that Dewey comes to philosophy itself as a kind of anthropologist, something we note as consistent with the influence of Franz Boas on Dewey (with whom Dewey was a colleague and intellectual ally at Columbia for about thirty-five years). This is further underscored by a lengthy quotation of anthropologist Bronislaw Malinowski on the meaning of culture (p. 290). The ongoing history of philosophy is itself a cultural activity. Indeed, citing James, Dewey declares that “The sickliest way in which a student of philosophy can approach his subject-matter is that of a search for ultimate impersonal revelation of truth.” (p. 16) Rather, let the philosopher have the pragmatic attitude of openness “... to truth from whatever source it comes” (ibid).With that, Dewey once again turns to the Greeks, who initiated “The Discovery of Rational Discourse” (Ch. III) as underscored by the Socratic means of cooperative discourse, with the dialogues—not lectures—being evidence of the Athenian philosophical revolution in turning “from discussing nature and giving an account of it to the examination of the nature and procedure of discussion and report” (p. 38). Yet this project, despite its initial promise, failed for lack of a genuine logic of experimentation or inquiry. Then philosophy focused on going beyond the natural, beginning with the medieval “Search for Salvation” (Ch. IV, a significantly less developed and unified chapter draft). “Modern” philosophers then rightly replaced grand cosmic schemes with a focus on human nature (Ch. V), but they went too far with their introspective methods, gradually resulting in the same consequence supernaturalism had produced: a dualism of mind and nature, as if human nature is somehow not a part of nature. As we recall from Human Nature and Conduct (1922), human nature is not independent of but rather interdependent (or, using Dewey’s later term, transactional) with the rest of nature. The key is to avoid hypostatizing mind and better to talk of culture as nature. [End Page 123]With the Renaissance onward, humans have been “Wandering between Two Worlds” (Ch. VI), and endless arguments between “rationalists” and “empiricists” overlook what these camps share, namely a psychology assuming a fundamental split between subjective/objective and assumptions about certainty as founded upon various first principles or substances. The result is the stagnation of philosophy while science flourishes. Dewey cites Bertrand Russell as an example of continued insistence on such a priori principles (p. 106).We find ourselves in an epoch split between scientism and moral and religious fundamentalism, the result of a lingering tenacious investment in bad elements from ancient and medieval...

This thesis constructs an Interactive Theory of Beauty to change the way we think about beauty and aesthetic form, in order to resolve the conceptual discrepancies between the features that characterize the traditional concept of beauty and the features of the phenomenology of beauty. The assumptions that underlie these discrepancies are identified. I hypothesize an alternative assumption that would need to be the case to resolve the tensions between the traditional concept and the phenomenology. This involves rejecting the idea that (...) beauty is an objective property of the object, and instead considering the possibility that beauty is an awareness of a certain aspect of the perceptual processing of the object. As such, beauty would be neither purely subjective nor purely objective; but a relational property. This hypothesis is mapped out in terms of a computational model of perception. The argument relies on the explanatory power of this conception of beauty. I employ my central hypothesis to explain how beauty can be both universal and subjective; an experience of the aesthetic form of the object which can, in some cases, supervene on representational content; and a property which is experienced as inferred from more basic properties, yet ineffable. While I focus mainly on visual beauty, I suggest applications for musical beauty and haptic beauty, particularly in non-sighted persons. This Interactive Theory of Beauty also accounts for the instrumentality of beauty, which is a feature of scientific and mathematical beauty. If my central hypothesis is correct, then the experience of beauty may offer insights into the nature of creativity in all fields of enquiry. (shrink)

Inference to the Best Explanation (IBE) is widely criticized for being an unreliable form of ampliative inference – partly because the explanatory hypotheses we have considered at a given time may all be false, and partly because there is an asymmetry between the comparative judgment on which an IBE is based and the absolute verdict that IBE is meant to license. In this paper, I present a further reason to doubt the epistemic merits of IBE and argue that (...) it motivates moving to an inferential pattern in which IBE emerges as a degenerate limiting case. Since this inferential pattern is structurally similar to an argumentative strategy known as Inferential Robustness Analysis (IRA), it effectively combines the most attractive features of IBE and IRA into a unified approach to non-deductive inference.

The question of the dimensionality of space has informed the development of physics since the beginning of the twentieth century in the quest for a unified picture of quantum processes and gravitation. Scientists have worked within various approaches to explain why the universe appears to have a certain number of spatial dimensions. The question of why space has three dimensions has a genuinely philosophical nature that can be shaped as a problem of justifying a contingent necessity of the world. (...) In contrast to explanations of three-dimensionality based on anthropic arguments, we support the search for a theory that provides a justification for the dimensionality of space based on a combination of deductive and inductive reasoning applied to science. In doing so, we argue that Kant correctly approached the question in “Thoughts on the true estimation of living forces” by connecting space dimensionality and the inverse square law. In expounding the strategy of Kant’s argument, we describe the main features of a general Kantian explanation of the dimensionality of space and discuss them with respect to current accounts of explanation in the philosophy of science, such as inference to the best explanation and the deductive-nomological model.

In this book we offer a theory of the self, whose core ideas are that the self is a process of self-representing, and this process aims mainly at defending the self-conscious subject against the threat of its metaphysical inconsistence. In other words, the self is essentially a repertoire of psychological manoeuvres whose outcome is a self-representation aimed at coping with the fundamental fragility of the human subject. Our picture of the self differs from both the idealist and the eliminative approaches (...) widely represented in contemporary discussion. Against the idealist approach, we deny that the self is something primitive and logically prior. Rather, we take it to be the result of a process of construction that starts with subpersonal unconscious processes. On the other hand, we also reject the anti-realistic, eliminative argument that, from the non-primary, derivative nature of the self, infers its status as an illusory by-product of real neurobiological events, devoid of any explanatory role.

In 1962 a mimeographed sheet of paper fell into my possession. It had been prepared by Ernest Adams of the Philosophy Department at Berkeley as a handout for a colloquim. Headed 'SOME FALLACIES OF FORMAL LOGIC' it simply listed eleven little pieces of reasoning, all in ordinary English, and all absurd. I still have the sheet, and quote a couple of the arguments here to give the idea. • If you throw switch S and switch T, the motor will start. (...) There fore, either if you throw switch S the motor will start, or, if you throw switch T the motor will start. • It is not the case that if John passes history he will graduate. Therefore, John will pass history. The disconcerting thing about these inferences is, of course, that under the customary truth-functional interpretation of and, or, not, and if-then, they are supposed to be valid. What, if anything, is wrong? At first I was not disturbed by the examples. Having at that time consider able personal commitment to rationality in general and formal logic in par ticular, I felt it my duty and found myself easily able (or so I thought) to explain away most of them. But on reflection I had to admit that my expla nations had an ad hoc character, varying suspiciously from example to example. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:In DialogueResponse to Roger Mantie, “Bands and/as Music Education: Antinomies and the Struggle for Legitimacy,” Philosophy of Music Education Review 20, no 1 (Spring 2012): 63–81Panagiotis A. KanellopoulosRoger Mantie’s paper “Bands and/as Music Education: Antinomies and the Struggle for Legitimacy,”1 looks at the educational band-world through a perspective informed, in his words, by “three concepts flowing from the work of Michel Foucault: power, truth, and discourse.” This is an (...) ambitious intention, and to my mind, it has to be carried through with courage, and by that I mean addressing the full consequences of the project at hand.Mantie argues that there is a break between the traditional musical practices of “American wind bands” and the contemporary institutionalization of banding that has induced the creation of the “pedagogical band world” within contemporary school and university contexts. Whereas the former aimed to promote music “of the people and for the people,” institutionalized music education band [End Page 191] practices sought to solve “the problem of their educational legitimacy in adopting the presentation of ‘art music’ as their raison d’etre.” Whereas, in the “old band world” what mattered most was “the here and now celebration of immanent time, space, and place,” contemporary approaches to band as a means for music education celebrate “the timeless and unassailable qualities of the music itself.” This break entailed the creation of “a schizophrenic creature that suffers a continual crisis of identity.”On IdealizationOne of the core issues that emerge out of Mantie’s text relates to a not uncommon tendency to regard a non-institutionalized form of musical practice as constituting the “true” instantiation of this very musical practice, as opposed to the subsequent contaminated version that is the inevitable result of institutionalization.2 Such an approach seems to me quite at odds with Foucault’s nominalism, with his emphasis on problematization and eventalization or eventialization [évènementialisation]—“the bringing to light of ‘ruptures of evidence,’”3 which is rooted in methodological individualism.4 For Foucault, eventalization entails a “breach of self evidence.... It means making visible a singularity at places where there is a temptation to invoke a historical constant, an immediate anthropological trait, or an obviousness which imposes itself uniformly on all.”5 Edward Said has noted Foucault’s “predilection for the analysis of discontinuous but actual spaces,”6 in other words, his tendency to adopt a spatial instead of temporal perspective, preferring to talk about places, fields, loci, topical institutions, events, their singularity and their discontinuities and fragmentations, instead of unified processes of temporal developments.Mantie’s text tends to take as granted issues that should be regarded as loci of problematization. In his account, “the American wind band” (and despite his cautious comment in a footnote) is regarded as a bounded cultural phenomenon that constitutes an enactment of democracy, based on openness, inclusiveness, informality, and plurality, elements that have, it is suggested, vanished from its contemporary pedagogical incarnations. One of the most important strengths of a Foucauldian approach is that it does not help us to easily take sides. Taking as an unquestionable fact that traditional band practices were an instance of practicing democracy masks active processes of exclusion, operating on the basis of racial and gender oppression and discrimination. A Foucauldian perspective might be important for developing multiple local micro-historical accounts of traditional wind band practices, emphasizing not only what these practices forefront (thus contrasting it with contemporary practices) but, most importantly, what they exclude or silence.7Instead of claiming that “bands were simply appropriated by schools,” an argument [End Page 192] that implies a uniform passage from an original form of the band world to its educational distortion, the aim could be “to fragment what was thought unified, and show the heterogeneity of consistency,”8 directing our attention to the microphysics of power/knowledge relationships as they emerge in different (educational or other) contexts and in the passage from older to more recent practices. A Foucauldian view of the relationships between old and contemporary band practices, as well as the position of the latter within larger music education discourses would not lead to a process of discovering “uncontaminated...

This article offers several contributions to the interdisciplinary project of responsible research and innovation in data science and AI. First, it provides a critical analysis of current efforts to establish practical mechanisms for algorithmic auditing and assessment to identify limitations and gaps with these approaches. Second, it provides a brief introduction to the methodology of argument-based assurance and explores how it is currently being applied in the development of safety cases for autonomous and intelligent systems. Third, it generalises this method (...) to incorporate wider ethical, social, and legal considerations, in turn establishing a novel version of argument-based assurance that we call ‘ethical assurance.’ Ethical assurance is presented as a structured method for unifying the myriad practical mechanisms that have been proposed. It is built on a process-based form of project governance that enlists reflective innovation practices to operationalise normative principles, such as sustainability, accountability, transparency, fairness, and explainability. As a set of interlocutory governance mechanisms that span across the data science and AI lifecycle, ethical assurance supports inclusive and participatory ethical deliberation while also remaining grounded in social and technical realities. Finally, this article sets an agenda for ethical assurance, by detailing current challenges, open questions, and next steps, which serve as a springboard to build an active (and interdisciplinary) research programme as well as contribute to ongoing discussions in policy and governance.

This book investigates the role of inference in argumentation, considering how arguments support standpoints on the basis of different loci. The authors propose and illustrate a model for the analysis of the standpoint-argument connection, called Argumentum Model of Topics. A prominent feature of the AMT is that it distinguishes, within each and every single argumentation, between an inferential-procedural component, on which the reasoning process is based; and a material-contextual component, which anchors the argument in the interlocutors’ cultural (...) and factual common ground. The AMT explains how these components differ and how they are intertwined within each single argument. This model is introduced in Part II of the book, following a careful reconstruction of the enormously rich tradition of studies on inference in argumentation, from the antiquity to contemporary authors, without neglecting medieval and post-medieval contributions. The AMT is a contemporary model grounded in a dialogue with such tradition, whose crucial aspects are illuminated in this book. (shrink)

In evolutionary biology, niche construction is sometimes described as a genuine evolutionary process whereby organisms, through their activities and regulatory mechanisms, modify their environment such as to steer their own evolutionary trajectory, and that of other species. There is ongoing debate, however, on the extent to which niche construction ought to be considered a bona fide evolutionary force, on a par with natural selection. Recent formulations of the variational free-energy principle as applied to the life sciences describe the properties of (...) living systems, and their selection in evolution, in terms of variational inference. We argue that niche construction can be described using a variational approach. We propose new arguments to support the niche construction perspective, and to extend the variational approach to niche construction to current perspectives in various scientific fields. (shrink)

The vast majority of contributions to the literature on spirituality in nursing make extravagant claims about transcendence, eternity, the numinous, higher powers, higher levels of existence, invisible forces, cosmic unity, the essence of humanity, or other supernatural concepts. Typically, these assertions are made without the support of argument or evidence; and, as a consequence, alternative ways of theorizing ‘spirituality’ have been closed off, while the lack of consistent scholarship has turned the topic into a metaphysical backwater. In this paper, I (...) adopt a different premise, rejecting unsupported claims, and surveying the ‘spirituality’ terrain from a naturalistic and reductionist perspective. I argue that, if we rid ourselves of non‐naturalistic assumptions, we will discover theoretical and clinical resources in health psychology, social psychology, neuropsychology, and pharmacopsychology – resources which confirm that it is possible to conceptualize the study of existential concerns, and how health professionals might respond to them, in a properly scientific manner. In order to illustrate the potential usefulness of these resources, I will take palliative care as an example. (shrink)

New omnivorism is a term coined by Andy Lamey to refer to arguments that – paradoxically – our duties towards animals require us to eat some animal products. Lamey’s claim to have identified a new, distinctive position in food ethics is problematic, however, for some of his interlocutors are not new (e.g., Leslie Stephen in the nineteenth century), not distinctive (e.g., animal welfarists), and not obviously concerned with eating animals (e.g., plant neurobiologists). It is the aim of this paper to (...) bolster Lamey’s argument that he has identified a novel, unified, and intriguing position (or set of positions) in animal ethics and the philosophy of food. We distinguish new omnivorism from four other non-vegan positions and then differentiate three versions of new omnivorism based on the kinds of animal products they propose we consume. We conclude by exploring a range of argumentative strategies that could be deployed in response to the new omnivore. (shrink)

The semantic paradoxes and the paradoxes of vagueness display remarkable family resemblances. In particular, the same non-classical logics have been applied to both kinds of paradoxes. These facts have been taken by some authors to suggest that truth and vagueness require a unified logical framework. Some authors go further, and argue that truth is itself a vague or indeterminate concept. Importantly, however, there currently is no identification of what the common features of semantic and soritical paradoxes exactly consist in. (...) This is what we aim to do in this work: we analyze semantic and soritical paradoxes, and develop our analysis into a theory of paradoxicality. The unification of the paradoxes of truth and vagueness we propose here has a wide scope, but for the sake of concreteness we focus on four three-valued logics. (shrink)

SummaryGene transcription is strictly controlled by the interplay of regulatory events at gene promoters and gene‐distal regulatory elements called enhancers. Despite extensive studies of enhancers, we still have a very limited understanding of their mechanisms of action and their restricted spatio‐temporal activities. A better understanding would ultimately lead to fundamental insights into the control of gene transcription and the action of regulatory genetic variants involved in disease. Here, I review and discuss pros and cons of state‐of‐the‐art genomics methods to localize (...) and infer the activity of enhancers. Among the different approaches, profiling of enhancer RNAs yields the highest specificity and may be superior in detecting in vivo activity. I discuss their apparent similarities to promoters, which challenge the established view of enhancers and promoters as distinct entities, and present a unifying model of regulatory elements in transcriptional regulation, in which activity, transcriptional output and regulatory function is context specific.

We examine metonymy at psycho- and neurolinguistic levels, seeking to adjudicate between two possible processing implementations. We compare highly conventionalized systematic metonymy to lesser-conventionalized circumstantial metonymy. Whereas these two metonymy types differ in terms of contextual demands, they each reveal a similar dependency between the named and intended conceptual entities. We reason that if each metonymy yields a distinct processing time course and substantially non-overlapping preferential localization pattern, it would not only support a two-mechanism view but would suggest that conventionalization (...) acts as a linguistic categorizer. By contrast, a similar behavior in time course and localization would support a one-mechanism view and the inference that conventionalization acts instead as a modulator of contextual felicitousness, and that differences in interpretation introduced by conventionalization are of degree, not of kind. Results from three paradigms: self-paced reading, event-related potentials, and functional magnetic resonance imaging, reveal the following: no main effect by condition for either metonymy type immediately after the metonymy trigger, and a main effect for only the Circumstantial metonymy one word post-trigger ; a N400 effect across metonymy types and a late positivity for Circumstantial metonymy ; and a highly overlapping activation connecting the left ventrolateral prefrontal cortex and the left dorsolateral prefrontal cortex. Altogether, the pattern observed does not reach the threshold required to justify a two-mechanism system. Instead, the pattern is more naturally understood as resulting from the implementation of a generalized referential dependency mechanism, modulated by degree of context dependence/conventionalization, thus supporting architectures of language whereby “lexical” and “pragmatic” meaning relations are encoded along a cline of contextual underspecification.

Inferences from scientific success to the approximate truth of successful theories remain central to the most influential arguments for scientific realism. Challenges to such inferences, however, based on radical discontinuities within the history of science, have motivated a distinctive style of revision to the original argument. Conceding the historical claim, selective realists argue that accompanying even the most revolutionary change is the retention of significant parts of replaced theories, and that a realist attitude towards the systematically retained constituents of our (...) scientific theories can still be defended. Selective realists thereby hope to secure the argument from success against apparent historical counterexamples. Independently of that objective, historical considerations have inspired a further argument for selective realism, where evidence for the retention of parts of theories is itself offered as justification for adopting a realist attitude towards them. Given the nature of these arguments from success and from retention, a reasonable expectation is that they would complement and reinforce one another, but although several theses purport to provide such a synthesis the results are often unconvincing. In this paper I reconsider the realist’s favoured type of scientific success, novel success, offer a revised interpretation of the concept, and argue that a significant consequence of reconfiguring the realist’s argument from success accordingly is a greater potential for its unification with the argument from retention.Keywords: Scientific realism; Pessimistic meta-induction; Success; Progress; Aether; Novelty.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.1 (2003) 121-122 [Access article in PDF] Harold Tarrant. Plato's First Interpreters. Ithaca, NY: Cornell University Press, 2000. Pp. viii + 263. Cloth, $55.00. This is Tarrant's third book on the ancient Platonist tradition, following his Scepticism or Platonism? (1985) and Thrasyllan Platonism (1993). In those earlier volumes his focus was on the first centuries bc and ad. Here his scope is much (...) wider. Stating that "Platonic interpretation is today at a crossroads," he has written a book that explores "ancient attempts to wrestle with this corpus," with the ultimate objective "to encourage a fresh, almost primitive reading of Plato himself" (vii).He begins engagingly by confronting the ancients with questions any modern reader of Plato must ask: What kind of text is this? Are there doctrines here? Where do I look for Plato's doctrines? The second part of his book is a historical survey, taking us from Plato, the early Academy and Aristotle, through the Hellenistic and early Roman Imperial period, and concluding with the principal Neoplatonist interpreters. In the third and longest part, he focuses on the interpretation of specific dialogues, giving most space to the Gorgias and Theaetetus, but also dealing in particular detail with the Meno, Parmenides, and Philebus. Something is said about every dialogue, but Tarrant writes only briefly about such major works as the Republic and Timaeus. He explains his selectivity (not very convincingly) as due to his wish to "discuss issues of meta-interpretation, with emphasis on the period before Plotinus" (198).Taking his book as a whole, one realizes that few strands of modern interpretation were not prefigured to quite a large extent in antiquity. The two most obvious exceptions are the chronological and developmental approach (Early, Middle, and Late), at present under strong attack from some quarters, and the theological, numerological, and allegorical readings practiced by Neoplatonists. Plato's ancient interpreters were doctrinal unitarians, but they implicitly anticipated our tendency to distinguish "Socratic dialogues," which some of them called "gymnastic" and "inquisitive," from such "canonical" works as the Phaedo,Republic, Symposium, and Timaeus, to which they applied the labels "dogmatic" and "expository." And they recognized that both types of characteristics could be found in the same dialogue, as in the Meno and Theaetetus. Plato himself, they proposed, spoke primarily through the voices of Socrates, Timaeus, and the Eleatic and Athenian strangers; but other characters, such as Pausanias in the Symposium, or Protagoras in the dialogue of that name, utter thoughts with some philosophical value. In explaining difficult passages of one dialogue, they would typically refer to passages from other parts of the corpus. An especially intriguing instance is the strategy of the Anonymous Commentator on the Theaetetus, who reads the Meno into the dialogue on which he is officially commenting.Ancient scholars, just like ourselves, asked questions about the unifying themes of complex dialogues. Hence the sub-titles given to certain works: "On the soul" for the Phaedo, and "On justice" for the Republic, etc. For Olympiodorus (whose commentary on the Gorgias Tarrant has recently co-edited [Leiden, 1998]), earlier interpreters have seriously erred by giving too limited an account of that dialogue's scope. It is not, he says, simply about rhetoric, nor about justice and injustice; nor is its theme the divine demiurge (as some Neoplatonists had strangely proposed, on the basis of the concluding myth). Rather, the subject of the Gorgias is "the ethical principles that lead to constitutional well-being" (125). [End Page 121] However, Olympiodorus's eminently "sensible" reading (as Tarrant calls it) is deeply embedded in the Neoplatonic contrast between the "purificatory virtues" of the Phaedo and the "constitutional virtues" of Republic4.Strong or weak scepticism, esotericism, unwritten doctrines, spurious versus genuine, a canon of central dialogues, dramatic considerations, and the philosophical importance or non-importance of the dialogues' prologues—all of these are interpretive approaches that Tarrant surveys in this immensely learned book, and all of them continue to resonate for us. Modern scholars, who emphasize the literary and philosophical unity of each dialogue, are walking... (shrink)

In this paper I defend a unified approach to knowledge and understanding. Both are achievements due to cognitive abilities or skills. The difference between them is a difference of aspects. Knowledge emphasizes the successful aspect of an achievement and the exclusion of epistemic luck, whereas understanding emphasizes the agent's contribution in bringing about an achievement through the exercise of one's cognitive skills. Knowledge and understanding cannot be separated. I argue against the claim that understanding is distinct from knowledge (...) because the former is compatible with environmental luck. Achievements rule out environmental luck because abilities can be exercised only in their proper environment. I also reject the intellectualist claim that understanding requires the ability to explain what one intends to understand. The understanding of an item is reflected in our ability to solve cognitive tasks using that item. The more tasks one can deal with by using an item, the deeper is one’s understanding of that item. Being able to explain why a claim holds is not necessary for possessing understanding, even though it may be necessary for accomplishing some very specific tasks. Neither understanding nor knowledge require any kind of second-order cognition by default. (shrink)

The goal of this paper is to propose a unified approach to the split scope readings of negative indefinites, comparative quantifiers, and numerals. There are two main observations that justify this approach. First, split scope shows the same kinds of restrictions across these different quantifiers. Second, split scope always involves low existential force. In our approach, following Sauerland, natural language determiner quantifiers are quantifiers over choice functions, of type <<,t>,t>. In split readings, the quantifier over choice (...) functions scopes above other operators (such as intensional verbs like must or can). Determiner quantifiers leave a choice-function trace when they move and this trace combines with the noun restriction, which is interpreted low. That split scope always involves low existential force is derived, without stipulation, from Kratzer’s idea that low existential force can be achieved via binding (into the noun restriction).

Formal models of argumentation have been investigated in several areas, from multi-agent systems and artificial intelligence (AI) to decision making, philosophy and law. In artificial intelligence, logic-based models have been the standard for the representation of argumentative reasoning. More recently, the standard logic-based models have been shown equivalent to standard connectionist models. This has created a new line of research where (i) neural networks can be used as a parallel computational model for argumentation and (ii) neural networks can (...) be used to combine argumentation, quantitative reasoning and statistical learning. At the same time, non-standard logic models of argumentation started to emerge. In this paper, we propose a connectionist cognitive model of argumentation that accounts for both standard and non-standard forms of argumentation. The model is shown to be an adequate framework for dealing with standard and non-standard argumentation, including joint-attacks, argument support, ordered attacks, disjunctive attacks, meta-level attacks, self-defeating attacks, argument accrual and uncertainty. We show that the neural cognitive approach offers an adequate way of modelling all of these different aspects of argumentation. We have applied the framework to the modelling of a public prosecution charging decision as part of a real legal decision making case study containing many of the above aspects of argumentation. The results show that the model can be a useful tool in the analysis of legal decision making, including the analysis of what-if questions and the analysis of alternative conclusions. The approach opens up two new perspectives in the short-term: the use of neural networks for computing prevailing arguments efficiently through the propagation in parallel of neuronal activations, and the use of the same networks to evolve the structure of the argumentation network through learning (e.g. to learn the strength of arguments from data).

Lifestyle diseases constitute an increasing proportion of health problems and this trend is likely to continue. A better understanding of the responsibility argument is important for the assessment of policies aimed at meeting this challenge. Holding individuals accountable for their choices in the context of health care is, however, controversial. There are powerful arguments both for and against such policies. In this article the main arguments for and the traditional arguments against the use of individual responsibility as a criterion for (...) the distribution of scarce health resources will be briefly outlined. It is argued that one of the most prominent contemporary normative traditions, liberal egalitarianism, presents a way of holding individuals accountable for their choices that avoids most of the problems pointed out by the critics. The aim of the article is to propose a plausible interpretation of liberal egalitarianism with respect to responsibility and health care and assess it against reasonable counter-arguments. (shrink)

Causality offers the first comprehensive coverage of causal analysis in many sciences, including recent advances using graphical methods. Pearl presents a unified account of the probabilistic, manipulative, counterfactual and structural approaches to causation, and devises simple mathematical tools for analyzing the relationships between causal connections, statistical associations, actions and observations. The book will open the way for including causal analysis in the standard curriculum of statistics, artificial intelligence, business, epidemiology, social science and economics.

The notions of inference and default are used in pragmatics with different meanings, resulting in theoretical disputes that emphasize the differences between the various pragmatic approaches. This paper is aimed at showing how the terminological and theoretical differences concerning the two aforementioned terms result from taking into account inference and default from different points of view and levels of analysis. Such differences risk making a dialogue between the theories extremely difficult. However, at a functional level of analysis the (...) different theories, definitions, and approaches to interpretation can be compared and integrated. At this level, the standardization of pragmatic inferences can be regarded as the development of a specific type of presumptions, used to draw prima-facie interpretations. (shrink)

The problems that arise from the presence of self-attacking ar- guments and odd-length cycles of attack within argumentation frameworks are widely recognized in the literature on defeasible argumentation. This paper introduces two simple semantics to capture different intuitions about what kinds of arguments should become justified in such scenarios. These semantics are modeled upon two extensions of argumentation frameworks, which we call sustainable and tolerant. Each one is constructed on the common ground of the powerful concept of (...) admissibility introduced by Dung in [10]. The novelty of this approach consists in viewing the admissibility of a subset of arguments as relative to potentially challenging subsets of arguments. Both sustainable and tolerant semantics are more credulous than preferred semantics (i.e. they justify at least the same arguments, and possibly more). Given certain sufficient conditions they coincide among them as well as with other semantics introduced by Dung. (shrink)

According to the Bayesian paradigm in the psychology of reasoning, the norms by which everyday human cognition is best evaluated are probabilistic rather than logical in character. Recently, the Bayesian paradigm has been applied to the domain of argumentation, where the fundamental norms are traditionally assumed to be logical. Here, we present a major generalisation of extant Bayesian approaches to argumentation that utilizes a new class of Bayesian learning methods that are better suited to modelling dynamic and conditional (...) inferences than standard Bayesian conditionalization, is able to characterise the special value of logically valid argument schemes in uncertain reasoning contexts, greatly extends the range of inferences and argumentative phenomena that can be adequately described in a Bayesian framework, and undermines some influential theoretical motivations for dual function models of human cognition. We conclude that the probabilistic norms given by the Bayesian approach to rationality are not necessarily at odds with the norms given by classical logic. Rather, the Bayesian theory of argumentation can be seen as justifying and enriching the argumentative norms of classical logic. (shrink)
