The standard assumptions that underlie many conceptual and quantitative frameworks do not hold for many complex physical, biological, and social systems. Complex systems science clarifies when and why such assumptions fail and provides alternative frameworks for understanding the properties of complex systems. This review introduces some of the basic principles of complex systems science, including complexity profiles, the tradeoff between efficiency and adaptability, the necessity of matching the complexity of systems to that of their environments, multiscale (...) analysis, and evolutionary processes. Our focus is on the general properties of systems as opposed to the modeling of specific dynamics; rather than provide a comprehensive review, we pedagogically describe a conceptual and analytic approach for understanding and interacting with the complex systems of our world. This paper assumes only a high school mathematical and scientific background so that it may be accessible to academics in all fields, decision-makers in industry, government, and philanthropy, and anyone who is interested in systems and society.

ABSTRACT: This article addresses two main concerns: first, the relation between the truth/falsehood and purity/impurity criteria as applied to pleasure, and, second, the status of our pleasures of learning. In addressing the first, I argue that Plato keeps the truth/falsehood and purity/impurity criteria distinct in his assessment of pleasures and thus leaves room for the possibility of hybrid pleasures in the form of true impure pleasures and false pure pleasures. In addressing the second issue, I show that Plato's view is (...) perfectly able to accommodate an understanding of our pleasures of learning as pure pleasures even if such pleasures are preceded by awareness of a lack (ignorance).RÉSUMÉ: Cet article aborde deux concepts principaux: premièrement, la relation entre les critères de vérité/fausseté et de pureté/impureté appliqués au plaisir, et deuxièmement, le statut de notre plaisir d'apprendre. En abordant le premier concept, j'argumente que Platon tient distincts les critères de vérité/fausseté et de'pureté Iimpureté dans son évaluation du plaisir, laissant ouverte la possibilité de plaisirs hybrides sous forme de vrais plaisirs impurs et faux plaisirs purs. En abordant le deuxième concept, je montre que le point de vue de Platon est parfaitement capable d'accommoder la compréhension de nos plaisirs d'apprendre comme plaisirs purs si de tels plaisirs sont précédés par la conscience d'un manque (ignorance).

The fundamental relations that underlie cognitive comparisons—“same” and “different”—can be defined at multiple levels of abstraction, which vary in relational complexity. We compared response times to decide whether or not two sequentially‐presented patterns, each composed of two pairs of colored squares, were the same at three levels of abstraction: perceptual, relational, and system (higher order relations). For both 150 ms and 5 s inter‐stimulus intervals (ISIs), both with and without a masking stimulus, decision time increased with level of abstraction. Sameness (...) at lower complexity levels contributed to decisions based on the higher levels. The pattern of comparison times across levelswas not predictable solely from encoding times. The results indicated that relations at multiple levels of complexity can be abstracted and compared in working memory, with higher complexity levels requiring more processing time. We simulated the impact of relational complexity on response time using Learning and Inference with Schemas and Analogies (LISA), a computational model of relational comparisons based on dynamic binding of elements into roles in a relational working memory.

The main goal of this paper is to investigate whether humans are unique in using tools and artifacts. Non-human animals exhibit some impressive instances of tool and artifact-use. Chimpanzees use sticks to get termites out of a mound, beavers build dams, birds make nests, spiders create webs, bowerbirds make bowers to impress potential mates, etc. There is no doubt that some animals modify and use objects in clever and sophisticated ways. But how does this relate to the way in which (...) humans make and use objects to achieve their goals? To answer this question, this paper first presents a taxonomy of artifacts, identifying four overlapping categories, namely embodied, perceptual, cognitive, and affective artifacts. It then discusses definitions of animal tool-use, arguing that we need a more liberal approach, one that goes beyond the use of tools that are embedded in occurrent perception-action cycles. This paper ends by analysing how instances of animal tool and artifact-use can be classified according to the four identified categories, concluding that some animals use embodied, perceptual, cognitive, and affective artifacts. In this sense, humans are thus not unique in the kinds of tools and artifacts we use. What is unique, however, is our unprecedented flexibility and openness to deeply incorporate a large variety of complex tools and artifacts into our embodied, perceptual, cognitive, and affective systems.

Containing selected papers on the fundamentals and applications of Complexity Science, this multi-disciplinary book presents new approaches for resolving complex issues that cannot be resolved using conventional mathematical or software models. Complex Systems problems can occur in a variety of areas such as physical sciences and engineering, the economy, the environment, humanities and social and political sciences. Complexity Science problems, the science of open systems consisting of large numbers of diverse components engaged in rich interaction, can occur (...) in a variety of areas such as physical sciences and engineering, the economy, the environment, humanities and social and political sciences. The global behaviour of these systems emerges from the interaction of constituent components and is unpredictable but not random. The key attribute of Complex Systems is the ability to self-organise and adapt to unpredictable changes in their environment. (shrink)

This book explores the idea that self-knowledge comes in many varieties. We “know ourselves” through many different methods, depending on whether we attend to our propositional attitudes, our perceptions, sensations or emotions. Furthermore, sometimes what we call “self-knowledge” is not the result of any substantial cognitive achievement and the characteristic authority we grant to our psychological self-ascription is a conceptual necessity, redeemed by unravelling the structure of several interlocking concepts. This book critically assesses the main contemporary positions held on the (...) epistemology of self-knowledge. These include robust epistemic accounts such as inner sense views and theory-theories; weak epistemic accounts such as transparency theories and rational internalism and externalism; as well as expressivist and constitutivist approaches. The author offers an innovative “pluralist” position on self-knowledge, emphasizing the complexity of the phenomenon and its resistance to any “monistic” treatment, to pose new and intriguing philosophical challenges.

This is a comprehensive discussion of complexity as it arises in physical, chemical, and biological systems, as well as in mathematical models of nature. Common features of these apparently unrelated fields are emphasised and incorporated into a uniform mathematical description, with the support of a large number of detailed examples and illustrations. The quantitative study of complexity is a rapidly developing subject with special impact in the fields of physics, mathematics, information science, and biology. Because of the variety of (...) the approaches, no comprehensive discussion has previously been attempted. This book will be of interest to graduate students and researchers in physics (nonlinear dynamics, fluid dynamics, solid-state, cellular automata, stochastic processes, statistical mechanics and thermodynamics), mathematics (dynamical systems, ergodic and probability theory), information and computer science (coding, information theory and algorithmic complexity), electrical engineering and theoretical biology.

Increasingly in economics what had been considered to be unusual and unacceptable has come to be considered usual and acceptable, if not necessarily desirable. Whereas it had been widely believed that economic reality could be reasonably described by sets of pairs of linear supply and demand curves intersecting in single equilibrium points to which markets easily and automatically moved, now it is understood that many markets and situations do not behave so well. Economic reality is rife with nonlinearity, discontinuity, and (...) a variety of phenomena that are not so easily predicted or understood. At the same time the broad coherence of economic systems is more impressive than ever in the face of such phenomena. The order of the economy appears to emerge from the complex interactions that constitute the evolutionary process of the economy. These phenomena have come to be labeled as complexity in economics. Even what seems simple in economics generally arises from behavior not reflecting rational expectations; we live in a world that reflects the enormous variety and diversity of humanity in their knowledge, attitudes, and behaviors, interacting with each other in an enormous range of institutional frameworks. What emerges in the aggregate may have little to do with what happens at the individual level. But this aggregate cannot be simply described by some set of aggregate equations. It emerges out of the soup of the individual and particular with all its multiform interactions and peculiarities. (shrink)

“What does it mean to say that we live in a secular age?” This apparently simple question opens into the massive, provocative, and complex A Secular Age, where Charles Taylor positions secularism as a defining feature of the modern world, not the mere absence of religion, and casts light on the experience of transcendence that scientistic explanations of the world tend to neglect. -/- In Varieties of Secularism in a Secular Age, a prominent and varied group of scholars chart (...) the conversations in which A Secular Age intervenes and address wider questions of secularism and secularity.

We introduce a new Turing machine based concept of time complexity for functions on computable metric spaces. It generalizes the ordinary complexity of word functions and the complexity of real functions studied by Ko [19] et al. Although this definition of TIME as the maximum of a generally infinite family of numbers looks straightforward, at first glance, examples for which this maximum exists seem to be very rare. It is the main purpose of this paper to prove that, nevertheless, the (...) definition has a large number of important applications. Using the framework of TTE [40], we introduce computable metric spaces and computability on the compact subsets. We prove that every computable metric space has a c-proper c-admissible representation. We prove that Turing machine time complexity of a function computable relative to c-admissible c-proper representations has a computable bound on every computable compact subset. We prove that computably compact computable metric spaces have concise c-proper c-admissible representations and show by examples that many canonical representations are of this kind. Finally, we compare our definition with a similar one by Labhalla et al. [22]. Several examples illustrate the concepts. By these results natural and realistic definitions of computational complexity are now available for a variety of numerical problems such as image processing, integration, continuous Fourier transform or wave propagation.

Although much research on emotion and morality has treated emotion as a relatively undifferentiated construct, recent work shows that moral transgressions can evoke a variety of distinct emotions. To accommodate these results, we propose a multiple-appraisal model in which distinct appraisals lead to different moral emotions. The implications of this model for our understanding of the relationship between appraisals, emotions and judgments are discussed. The complexity of moral emotional experience presents a methodological challenge to researchers, but we submit that (...) a complete understanding of human morality must acknowledge the differentiated nature of moral emotions.

Using the work of Robert A. Kagan's intellectual contribution on the intensification of law, leading authorities in the study of the politics of regulation and litigation examine the consequences of the expansion and intensification of law, both in the United States and the rest of the world. Part One considers bureaucratic legalism, a terrain in which popular and political discourse often conceives as a pitched battle between business and government, and in which claims about quantity—"too much" and "too little"—take center (...) stage. Here, the contributors examine the many ways in which regulators and the regulated cooperate, and the extent to which regulated entities internalize norms and practices associated with bureaucratic. Part Two considers adversarial legalism, a term that even among academics is often reduced to "litigiousness." The chapters in this section show that adversarial legalism is a much more complex, contingent, and multi-sided phenomenon than the popular debate over litigiousness suggests. Part III examines Kagan's core concepts in a comparative framework. Although some sometimes treat adversarial legalism as an American disease, scholars are increasingly finding it proliferating elsewhere, and debating whether it can take a prominent role in nations quite different in tradition and political structure from the United States. Across the globe, law and legalism in all its forms, bureaucratic and adversarial, is becoming more intense, and thus more central to politics, public policy and everyday life. The consequences are profound. Yet commentary is often stuck on old questions. Does the intensification of law reflect the withering of other social institutions? Is it a sign of moral decay? Or is it, on another account, signaling a new era of respect for universal human rights? The Politics of Legalism takes us instead in directions relatively unexplored by both scholars and popular commentators on law. Like Kagan's scholarship, it moves beyond stale debates about litigiousness and overregulation, and invites us to think more imaginatively about how the rise of law and legalism will shape politics and social life in the 21st Century.

A great deal has been written over the past decade defending ‘higher-level’ causes by arguing that overdetermination is more complex than many philosophers initially thought. Although two shooters overdetermine the death of a firing squad victim, a baseball and its parts do not overdetermine the breaking of a window. But while these analyses of overdetermination have no doubt been fruitful, the focus on overdetermination—while ignoring other varieties of causal relation—has limited the discussion. Many of the cases of interest resemble (...) joint causes or a cause necessitating a simultaneous epiphenomenon as much as they resemble overdeterminers. If we are to fully understand higher-level causation, we need to distinguish it from these causal relations as well. This paper is dedicated to the task, focusing especially on the ‘threat’ that higher-level causes are epiphenomena necessitated by lower-level causes. (shrink)

Roger Koppl (2009, p. 1) argues that “Austrian economics is a school of thought within the broader complexity movement in economics.” Is he correct? While there are many who have argued for some overlapping between the two, I shall argue that this is probably an overly strong statement. The main reason is that there are substantial elements and strands within Austrian economics that do not fit in with any of the multiple varieties of complexity theory, even though there are some (...) that clearly do. While I have some disagreements with Koppl’s argument, I think that he does a good job of identifying some of the main strands of Austrian economics that are consistent with complexity thought. The most important of these are associated with the work of Friedrich A. Hayek, who.. (shrink)

Ecosystems, the human brain, ant colonies, and economic networks are all complex systems displaying collective behaviour, or emergence, beyond the sum of their parts. Complexity science is the systematic investigation of these emergent phenomena, and stretches across disciplines, from physics and mathematics, to biological and social sciences. This introductory textbook provides detailed coverage of this rapidly growing field, accommodating readers from a variety of backgrounds, and with varying levels of mathematical skill. Part I presents the underlying principles of (...) complexity science, to ensure students have a solid understanding of the conceptual framework. The second part introduces the key mathematical tools central to complexity science, gradually developing the mathematical formalism, with more advanced material provided in boxes. A broad range of end of chapter problems and extended projects offer opportunities for homework assignments and student research projects, with solutions available to instructors online. Key terms are highlighted in bold and listed in a glossary for easy reference, while annotated reading lists offer the option for extended reading and research. (shrink)

The picture of synthetic biology as a kind of engineering science has largely created the public understanding of this novel field, covering both its promises and risks. In this paper, we will argue that the actual situation is more nuanced and complex. Synthetic biology is a highly interdisciplinary field of research located at the interface of physics, chemistry, biology, and computational science. All of these fields provide concepts, metaphors, mathematical tools, and models, which are typically utilized by synthetic biologists (...) by drawing analogies between the different fields of inquiry. We will study analogical reasoning in synthetic biology through the emergence of the functional meaning of noise, which marks an important shift in how engineering concepts are employed in this field. The notion of noise serves also to highlight the differences between the two branches of synthetic biology: the basic science-oriented branch and the engineering-oriented branch, which differ from each other in the way they draw analogies to various other fields of study. Moreover, we show that fixing the mapping between a source domain and the target domain seems not to be the goal of analogical reasoning in actual scientific practice. (shrink)

Recently, the effort to counter Fake News faced a counter attack: academic »postmodernism « and »social constructivism« it was said—because they say that facts are soaked in prior interpretations—are either purveyors of Fake News or set the cultural context in which it flourishes. They do so by undermining confidence in inquiry governed by simple facts. That is erroneous, argues William E. Connolly, because postmodernism never said that facts or objectivity are ghostly, subjective or »fake«. However, that what was objective at (...) one time may become less so at a later date through the combination of a paradigm shift in theory, new powers of perception, new tests with refined instruments, and changes in natural processes such as species evolution. But the emergence of new theories and tests does not reduce objectivity to subjective opinion. Facts are real. Objectivity is important. But as you move up the scale of complexity with respect to facts and objectivity, it becomes clear that what was objective at one time may become subjective at another. Not because of Fake News or postmodernism. But because the complex relationships between theory, evidence and conduct periodically open up new thresholds. Colin Lang in turn rhetorically asks if »fake news« or »alternative facts« are a new carnival and Trump its dog and pony show? The idea of »fake news« and »alternative facts« as a carnival could not only help to see the constructedness of the media spectacle, but also provides a new perspective on Trump as an actor who is playing a particular role in this carnival, and that role is not one that any of us would describe as presidential. Many in the popular press have assumed it is just what it looks like, an infantilized narcissist, a parody of some Regan-era New York real estate tycoon straight out of a Bret Easton Ellis novel. The problem is that this description is all too obvious, and misses something fundamental about alternative facts, and the part that Trump is playing. A central assumption is, then, that the creation of alternative facts is one symptom of a more structural, paradigmatic shift in the persona of a president, one which has few correlates in the annals of political history. The closest analogy for his kind of performance is actually hinted at in the title of Trump’s greatest literary achievement: The Art of the Deal. Trump is playing the part of an artist, pilfering from the tactics of the avant-garde and putting them to very different ends. (shrink)

We study algebras whose elements are relations, and the operations are natural “manipulations” of relations. This area goes back to 140 years ago to works of De Morgan, Peirce, Schröder . Well known examples of algebras of relations are the varieties RCAn of cylindric algebras of n-ary relations, RPEAn of polyadic equality algebras of n-ary relations, and RRA of binary relations with composition. We prove that any axiomatization, say E, of RCAn has to be very complex in the following (...) sense: for every natural number k there is an equation in E containing more than k distinct variables and all the operation symbols, if 2 < n < ω. Completely analogous statement holds for the case n ω. This improves Monk's famous non-finitizability theorem for which we give here a simple proof. We prove analogous nonfinitizability properties of the larger varieties SNrnCAn + k. We prove that the complementation-free subreducts of RCAn do not form a variety. We also investigate the reason for the above “non-finite axiomatizability” behaviour of RCAn. We look at all the possible reducts of RCAn and investigate which are finitely axiomatizable. We obtain several positive results in this direction. Finally, we summarize the results and remaining questions in a figure. We carry through the same programme for RPEAn and for RRA. By looking into the reducts we also investigate what other kinds of natural algebras of relations are possible with more positive behaviour than that of the well known ones. Our investigations have direct consequences for the logical properties of the n-variable fragment Ln of first order logic. The reason for this is that RCAn and RPEAn are the natural algebraic counterparts of Ln while the varieties SNrnCAn + k are in connection with the proof theory of Ln. This paper appears in two parts. The first part contains the non-finite axiomatizability results. The present second part contains finite axiomatizations of some fragments together with a figure summarizing the finite and non-finite axiomatizability results in this area and the problems left open.

The theme of this book is formed by a pair of concepts: the concept of formal language as carrier of the precise expression of meaning, facts and problems, and the concept of algorithm or calculus, i.e. a formally operating procedure for the solution of precisely described questions and problems. The book is a unified introduction to the modern theory of these concepts, to the way in which they developed first in mathematical logic and computability theory and later in automata theory, (...) and to the theory of formal languages and complexity theory. Apart from considering the fundamental themes and classical aspects of these areas, the subject matter has been selected to give priority throughout to the new aspects of traditional questions, results and methods which have developed from the needs or knowledge of computer science and particularly of complexity theory. It is both a textbook for introductory courses in the above-mentioned disciplines as well as a monograph in which further results of new research are systematically presented and where an attempt is made to make explicit the connections and analogies between a variety of concepts and constructions.

Although much recent social science and humanities work has been a revolt against simplification, this volume explores the contrast between simplicity and complexity to reveal that this dichotomy, itself, is too simplistic. John Law and Annemarie Mol have gathered a distinguished panel of contributors to offer—particularly within the field of science studies—approaches to a theory of complexity, and at the same time a theoretical introduction to the topic. Indeed, they examine not only ways of relating to complexity but complexity _in (...) practice._ Individual essays study complexity from a variety of perspectives, addressing market behavior, medical interventions, aeronautical design, the governing of supranational states, ecology, roadbuilding, meteorology, the science of complexity itself, and the psychology of childhood trauma. Other topics include complex wholes in the sciences, moral complexity in seemingly amoral endeavors, and issues relating to the protection of African elephants. With a focus on such concepts as multiplicity, partial connections, and ebbs and flows, the collection includes narratives from Kenya, Great Britain, Papua New Guinea, the Netherlands, France, and the meetings of the European Commission, written by anthropologists, economists, philosophers, psychologists, sociologists, and scholars of science, technology, and society. _Contributors._ Andrew Barry, Steven D. Brown, Michel Callon, Chunglin Kwa, John Law, Nick Lee, Annemarie Mol, Marilyn Strathern, Laurent Thévenot, Charis Thompson. (shrink)

Psychoanalytic Complexity is the application of a multidisciplinary, explanatory theory to clinical psychoanalysis and psychotherapy. It carries with it incisive and pivotal attitudes that aim to transform our understanding of therapeutic action and the change process. Here, William Coburn offers a revolutionary and far-reaching counterpoint to the remnants of Cartesianism and scientism, respecting and encouraging human anomaly rather than pathologizing or obliterating the uniqueness of the individual person. In Psychoanaltyic Complexity, William Coburn explores the value of complexity theory previously understood (...) as an explanatory framework with which clinicians can better understand, retrospectively, therapeutic action and the change process. He further extends this sensibility by examining the ways in which such a rich theoretical framework can inform what clinicians can do, prospectively, to effect positive change within the therapeutic relationship. He persuasively argues that the medium of bringing to light new ways of relating, emotional experiencing, and meaning making resides in the fundamental attitudes derived from a complexity theory sensibility as applied to psychoanalysis and psychotherapy. Using a variety of clinical illustrations throughout, Psychoanalytic Complexity is a radical corrective to reductionism and the more traditional presumption that the problem lies with the patient and the cure lies with the therapist. It offers a new language, vocabulary, way of thinking, and a new way of being with others that are pivotal in arriving at affirmative therapeutic change. This book is intended for psychoanalysts, clinical psychologists, therapists, mental health counsellors, academics and teachers who are interested in new trends in psychoanalysis and psychotherapy.

The existence of complex predicates seems to support an abundant conception of properties. Specifically, the application conditions for complex predicates seem to be explained by the distribution of a sparser base of predicates. This explanatory link might suggest that the existence and distribution of properties expressed by complex predicates are explained by the existence and distribution of a sparser base of properties. Thus, complex predicates seem to legitimize the assumption of a wide array of properties. The (...) additional properties are no explanatory addition to the sparse base. I argue, however, that construing complex predicates as expressing properties undermines the explanatory links between simple and complex predications. The argument explores a variety of accounts of complex predicates currently on offer and develops a number of themes from the work of Herbert Hochberg. (shrink)

We use tools of mathematical logic to analyse the notion of a path on a complex algebraic variety, and are led to formulate a “rigidity” property of fundamental groups specific to algebraic varieties, as well as to define a bona fide topology closely related to etale topology. These appear as criteria for ℵ1-categoricity, or rather stability and homogeneity, of the formal countable language we propose to describe homotopy classes of paths on a variety, or equivalently, its universal (...) covering space.Technically, for a variety A defined over a finite field extension of the field Q of rational numbers, we introduce a countable language L describing the universal covering space of A, or, equivalently, homotopy classes of paths in A. Under some assumptions on A source we show that the universal covering space of A is an analytic Zariski structure [26]), and present an Lω1ω)-sentence axiomatising the class containing the structure and that is stable and homogeneous over elementary submodels. The “rigidity” condition on fundamental groups says that projection of the fundamental group of a variety is the fundamental group of the projection, up to finite index and under some irreducibility assumptions, and is used to prove that the projection of an irreducible closed set is closed in the analytic Zariski structure.In particular, we define an analytic Zariski structure on the universal covering space of an Abelian variety defined over a finite extension of the field Q of rational numbers.

The asymptotic limit theorems of information and control theories permit exploration of a surprising number of temperature-like measures and symmetry-breaking dynamics associated with cognition. Each of several markedly different perspectives produces a distinct temperature-analog, capturing a rich and highly-punctuated behavioral landscape across the complex, hierarchical cognitive phenomena that characterize life at every scale and level of organization. Theories of cognition may be confronted by canonical conundrums similar to those plaguing the study of consciousness and its regulation. In short, there (...) may be a spectrum of interacting cognitive ‘temperatures’ for organisms, social structures, institutions, information processing machines, and their composite entities, that varies across different systems, and between similar systems having undergone different individual developmental trajectories. The complexities of cognitive failure—leading to a vast array of pathologies—may be far stranger than generally recognized. (shrink)

We demonstrate a method for optimizing desired functionality in real complex chemical systems, using a genetic algorithm. The chemical systems studied here are mixtures of amphiphiles, which spontaneously exhibit a complex variety of self-assembled molecular aggregations, and the property optimized is turbidity. We also experimentally resolve the fitness landscape in some hyper-planes through the space of possible amphiphile formulations, in order to assess the practicality of our optimization method. Our method shows clear and significant progress after testing (...) only 1 % of the possible amphiphile formulations. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy called 'complex question (CQ)'. The fallacy of the CQ appears in two varieties. The implicit form distracts an interlocutor by assuming the truth of an unproven premise and shifting the focus of the argument in an unfounded direction. While the explicit form collapses two distinct questions into a single question such that a single answer would appear to satisfy both inquiries. The possibility that an undetected CQ might (...) lead a speaker to affirm additional, unspoken premises unintentionally makes this a popular tactic in police interrogations and debate cross‐examinations. Avoiding this rhetorical trap is only possible either by rejecting the question as posed and extemporaneously clarifying the situation on one's own terms or by remaining silent. (shrink)

We consider the varieties and directions of influence that the source and target domains involved in a conceptual metaphor can have on each other during the course of understanding metaphorical utterances based on the metaphor. Previous studies have been restricted both as to direction of influence and as to type of influence. They have been largely confined to the “forward” (source to target) direction of influence, and they have concentrated on the transfer of features or propositions and (to some extent) (...) the highlighting of aspects of a domain. By contrast, this article stresses the importance both of other varieties of influence (e.g., transfer of queries and uncertainty effects) and of “reverse” influence (target to source). We seek to curb the natural tendency to think that, because metaphor involves an overall move from source to target, therefore all inter-domain influences in the course of understanding go in that direction. The bulk of the article explores the theoretical issues involved. These issues have arisen out of a reasoning-based approach to metaphor, seeking to make best use of information from metaphorical utterance, context, source and target domains, and known metaphorical mappings, by applying a complex overall reasoning process. The article briefly explains the thorough implementation of reverse influence in a computer program for metaphorical reasoning called ATT-Meta, although the theoretical considerations are relevant to all disciplines concerned with metaphor. We make some suggestions for further computational and psychological research on metaphor. (shrink)

We consider the problem of recognizing important properties of logical calculi and find complexity bounds for some decidable properties. For a given logical system L, a property P of logical calculi is called decidable over L if there is an algorithm which for any finite set Ax of new axiom schemes decides whether the calculus L + Ax has the property P or not. In [11] the complexity of tabularity, pre-tabularity, and interpolation problems over the intuitionistic logic Int and over (...) modal logic S4 was studied, also we found the complexity of amalgamation problems in varieties of Heyting algebras and closure algebras. In the present paper we deal with positive calculi. We prove NP-completeness of tabularity, DP-hardness of pretabularity and PSPACE-completeness of interpolation problem over Int + . In addition to above-mentioned properties, we consider Beth's definability properties. Also we improve some complexity bounds for properties of superintuitionistic calculi. (shrink)

Steven Rose's book is essentially a plea for considering the variety and complexity of life and against simplistic reductions of human and animal behavioral phenomena to single genetic causes.

The concept of bias is pervasive in both popular discourse and empirical theorizing within philosophy, cognitive science, and artificial intelligence. This widespread application threatens to render the concept too heterogeneous and unwieldy for systematic investigation. This article explores recent philosophical literature attempting to identify a single theoretical category—termed ‘bias’—that could be unified across different contexts. To achieve this aim, the article provides a comprehensive review of theories of bias that are significant in the fields of philosophy of mind, cognitive science, (...) machine learning, and epistemology. It focuses on key examples such as perceptual bias, implicit bias, explicit bias, and algorithmic bias, scrutinizing their similarities and differences. Although these explorations may not conclusively establish the existence of a natural theoretical kind, pursuing the possibility offers valuable insights into how bias is conceptualized and deployed across diverse domains, thus deepening our understanding of its complexities across a wide range of cognitive and computational processes.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Varieties of Atheism: Connecting Religion and Its Critics ed. by David NewheiserPaul K. MoserThe Varieties of Atheism: Connecting Religion and Its Critics. Edited by David Newheiser. Chicago: University of Chicago Press, 2022. 216 pp. $32.50 paper; $99.00 hardcover.There are two general ways to approach a controversial topic. The first way defines the key terms for the topic as clearly as possible, in order to give contributors a (...) common focus. This manner of approach keeps participants on the same page, with a shared topic of conversation and debate. The second way does not bother to formulate shared definitions of key terms. Instead, it notes multiple uses of key terms in history, and it allows contributors to proceed with their preferred uses, despite considerable variation in uses.This book, emerging from a 2018 conference on religion and its critics, opts for the second way, leaving readers with a wide range of understandings of “atheism.” Its eight essays therefore often treat different topics, with little sense of a common query. Editor Newheiser looks for a common feature as follows: “These essays explore the complex relations of sympathy and resistance that connect particular atheisms with particular religious traditions” (2). He hopes that “the collection opens new possibilities for conversation between those who are religious and those who are not” (2).We naturally might ask what the hoped-for conversation is about. If it is about the truth of theism, we are faced with a potential belief about whether God exists. Many people are concerned about that matter, even if atheism includes components beyond a mere belief about God’s existence. Atheism, Newheiser proposes, “is a polyphonic assemblage that develops in conversation with religious traditions” (8). He also claims that the collection is helpful in “bracketing the timeworn debate over the existence of God” (9). Even if the debate is “timeworn,” it still could be vital to understanding many religious traditions, theistic and nontheistic. In addition, it could be central to an adequate understanding of atheism even if atheism includes many noncognitive features. Such important prospects deserve more attention than Newheiser and his contributors suggest.An Afterword by Constance M. Furey, “The Drama of Atheism,” tries to find some unity in the book’s essays. She reports that the contributors are “united in our interest in atheism’s diversity, and intrigued by the possibility that new studies of atheism might unravel the single thread linking religion to belief” (200). She adds that the book’s authors “collectively confirm that [End Page 94] atheism’s multifaceted drama has often been overshadowed by the huckster out front, luring passersby with a simple cry, ‘God! Alive or Dead? True or False?’” (201). I fail to see why the latter questions should be associated with a “huckster.” That seems to assign guilt by association, without needed good reasons.I cannot recall anyone, philosopher or theologian, arguing that historical atheists hold only that it is false that God exists. Interest in the issue of “True or False?” is prominent among philosophers and theologians, because they are interested in the nature of reality, with respect to the existence of a divine being. Such interests, however, are no threat to other areas of commitment and practice among atheists. Those other areas can get due attention while one maintains a keen interest in the question of God’s existence. I suggest, then, that the book has a misplaced emphasis in its (attempt at) jettisoning issues about the existence of God in connection with atheism. Such issues are central to historical atheism, even though other concerns and features accompany it.Furey looks for a special kind of “hope” in the collection’s essays. She cites the book’s editor in endorsing “a commitment to thoughtful life and living thought that holds ‘affirmation and negation together in tension,’... in ‘an ethical practice of openness to the unexpected’” (202). She exclaims: “What better place to find this hope, the holding of affirmation and negation together, than in a volume devoted to open inquiry and unexpected conclusions about atheism” (202). She does not say, however, what the praised “negation” consists in. Is this the negation of God’s existence... (shrink)

The control of floral organ identity has received much attention since the first homeotic genes were isolated five years ago. The homeotic factors may be subject to a bewildering variety of control mechanisms including spatial and temporal transcriptional regulation, autoregulation, mutual protein stabilization, specific heterodimerization, post‐transcriptional modification and interaction with accessory factors. Now another level of complexity has been added by the recent discovery that the ‘B function factors’ depend on each other for nuclear localization(1) and can act non‐cell‐autonomously (...) in a polar fashion(2).

This contribution offers reflections about Chilean Cybersyn, 50 years ago. In recent years, Cybersyn, has received significant attention. It was the brainchild of Stafford Beer, who conceived it to support the transformation of the Chilean economy from its bureaucratic history to hopefully create a vibrant and modern society, driven by cybernetic tools. These aspects have received much attention in recent times; however, in this contribution, I want to discuss how working in Cybersyn influenced my work after the coup of 1973. (...) Perhaps, for me, its major influence was in the management of complexity, through what I refer here as variety engineering and through the Viable System Model VSM as a paradigm to the management of relationships with implications to enterprises, society and the economy. After the 1973 coup major interest was in technological aspects of Cybersyn such as real-time management and its contribution to decision support and executive information systems. In the late 70s I was personally influenced by information management, but by the early 1980s my work moved towards methodological aspects of how to use the VSM. By 1989 I had created the VIPLAN method. Key questions I attempted to answer were, how to model the complexity of enterprises and their interactions with environmental agents. Later on, in the 1990s and 2000s, the main direction of my work was epistemological, ontological and methodological towards second-order cybernetics and relationships. Only in recent decades the political transformations proposed by Cybersyn have captured the imagination of many commentators. The confluence of social and cultural changes with information technology, data models, artificial intelligence, algorithms and several additional technological developments have challenged the excesses of capitalism, particularly after the banking crisis of 2008–2009. The purpose in this paper is discussing this evolution in the light of those early days in Chile. (shrink)

A variety V of Boolean algebras with operators is singleton-persistent if it contains a complex algebra whenever it contains the subalgebra generated by the singletons. V is atom-canonical if it contains the complex algebra of the atom structure of any of the atomic members of V.This paper explores relationships between these "persistence" properties and questions of whether V is generated by its complex algebras or its atomic members, or is closed under canonical embedding algebras or completions. (...) It also develops a general theory of when operations involving complex algebras lead to the construction of elementary classes of relational structures. (shrink)

The study of how languages differ in their portrayal of motion events has received much attention since Talmy provided the first detailed account of the phenomenon. Interest has extended from real, or factive motion, to imagined or fictive motion, and from there to metaphorical motion, in which experience in one sensory domain is understood in terms of motion. Studies of metaphorical motion have, however, concentrated so far on a limited number of sensory domains, principally vision, and drawn data from a (...) limited number of textual genres. The aim of this study is to identify the extent to which motion expressions are employed to express organoleptic sensory experiences, that is experiences of taste and smell. Drawing on analytical categories put forward by Talmy in his treatment of Satellite- and Verb-framed languages and on treatments based on Cognitive Metaphor Theory, and particularly the concept of ‘embodiment’, we investigate the variety and complexity of organoleptic Paths evidenced in two self-built corpora of craft beer reviews, one in Spanish, the other in English. We also compare the level of complexity evident in these sensory Path types with those of another, closely related, sensory domain: vision. The study finds, in line with related studies, that English has greater variety and complexity of sensory Paths than Spanish. A more unexpected result is the finding that organoleptic Paths are more varied and complex than visual Paths. This finding, then, may encourage us to reconsider Path complexity differences in sensory domains as a multifactorial issue and not simply as a cognitive-linguistic phenomenon. It is proposed here that external factors such as genre, or specifically, its communicative functions and linguistic constraints, coupled with the unique ‘perceptual landscapes’ created by each sensory modality, may transcend perceived physical boundaries of a Figure’s trajectory.

In recent years, (autonomy-centered) enactivism has been used to provide an integrative and relational account of mental conditions. A significant advancement lies in its naturalized and pluralistic treatment of normativity, which transcends traditional objectivist and normativist dichotomies. This article explores the varieties of normativity within this paradigm and their implications for understanding mental conditions. We address purported challenges associated with the integration of social normativity into the enactive naturalistic framework of cognition, particularly concerning mental conditions. Drawing upon the distinction between (...) the constitution problem and the status problem, we conceptualize mental conditions as intersubjectively constituted with an intersubjectively negotiated status. Adopting a participatory sense-making perspective, we address three challenges posed by social movements: (1) Hermeneutical dilemmas related to the ontological openness of mental health categories. (2) The difficulties and urgency to mitigate epistemic injustices. (3) The complex attribution of (social) responsibility in psychological wellbeing. In conclusion, this perspective prompts a reevaluation of epistemological assumptions, advocating for a second-person and engaged perspective on mental conditions. (shrink)

The purpose of this paper is to show an application of variety engineering in the social realm. It focuses on reducing environmental complexity by catalysing self-organizing processes. This catalysis is based on the use of Sen and Nussbaum’s capabilities approach. By doing this an organization may improve the quality of the relations with their clients by transforming environmental agents into new suppliers. This approach opens a new dimension of social responsibility for organizations. A particular case is presented in which (...) a regional university in Colombia faces the challenge of attending low-income students coming from small municipalities. They designed a strategy to offer low-cost housing and a daily balanced meal without using the university's own resources. Instead, they managed to involve some agents of the community by developing their capabilities. This kind of variety engineering shows the possibility of new forms of social responsibility in universities by incorporating the capabilities approach into their managerial practices. This is something that is currently under study in other universities. (shrink)

Helmut Reich’s theory of relational and contextual reasoning is a courageous initiative for the resolution of cognitive conflicts between apparently incompatible or incommensurable views. Built upon Piagetian logico-mathematical reasoning, cognitive complexity theory, and dialectical and analogical reasoning, it includes the development of a both/and logic inclusive of binary either/or logic. Reich provides philosophic, theoretical, and even initial empirical support for the development of this form of reasoning along with a heuristic for its application. A valuable step beyond the limits of (...) binary, static, and formal reasoning, it takes relationship, context, and perspectival variations seriously in an explicitly reflective and iterative system. We can and do address conflicts not resolvable by conventional appeals to logic or evidence, including those at epistemic boundaries or produced by belief-commitment differences. Although this form of reasoning has real promise, including stepping beyond complementarity in the religion-science dialogue, it seems better directed to causally explanatory theories than to other forms of rendering meaning. Finally, its coextension requirement may render it problematic where functionally coherent explananda cannot be identified or are themselves produced or constituted by a belief system. (shrink)

This article demonstrates how instructors of professionalism and ethics training programs can integrate a professional decision-making tool in training curricula. This tool can help trainees understand how to apply professional decision-making strategies to address the threats posed by a variety of psychological and environmental factors when they are faced with complex professional and ethical situations. We begin by highlighting key decision-making frameworks and discussing factors that may undermine the use of professional decision-making strategies. Then, drawing upon findings from (...) past research, we present the “SMART” professional decision-making framework: seeking help, managing emotions, anticipating consequences, recognizing rules and context, and testing assumptions and motives. Next, we present a vignette that poses a complex ethical and professional challenge and illustrate how each professional decision-making strategy could or should be used by characters in the case. To conclude, we review a series of educational practices and pedagogical tools intended to help trainers facilitate trainee learning, retention, and application of “SMART” decision-making strategies.

Social media is an endless source of texts and images about almost everything. Accordingly, the number of analyses based on this source increases daily. Among the numerous methods social media can be analysed by, our attention focusses on discourse analysis. DA is a complex approach which makes it possible to capture not only the linguistic characteristics of given texts, but also their socially constructive and socially constructed features. Therefore, we carried out a systematic examination of the articles at one (...) of the largest academic databases, EBSCO available in 2019 which used DA in social media research. Our investigation studies not only the geographical distribution of this corpus, but the different self-proclaimed DA approaches. Furthermore, we developed a three-level scale in order to capture the methodological complexity of the collected articles. At one end of the scale there are those research papers where discourse appears only as a label for the textual material gathered, without further indication of any DA theories or methodologies. The other end, however, refers to those research projects which applied DA both in their theoretical and methodological frameworks, providing complex discourse analytical investigations of social media texts. This way we were able to demonstrate the wide array of DA perspectives employed in social media research. (shrink)

Network analysis views complex systems as networks with well-defined structural properties that account for their complexity. These characteristics, which include scale-free behavior, small worlds and communities, are not to be found in networks such as random graphs and lattices that do not correspond to complex systems. They provide therefore a robust ground for claiming the existence of “complex networks” as a non-trivial subset of networks. The theory of complex networks has thus been successful in making systematically (...) explicit relevant marks of complexity in the form of structural properties, and this success is at the root of its current popularity. Much less systematic has been, on the other hand, the definition of the properties of the building components of complex networks. The obvious assumption is that these components must be nodes and links. Generally, however, the internal structure of nodes is not taken into account, and links are serendipitously identified by the perspective with which one looks at the network to be analyzed. For instance, if the nodes are Web pages that contain information about scientific papers, one point of view will match the relevant links with hyperlinks to similar Web pages, and another with citations of other articles. We intend to contribute here a systematic approach to the identification of the components of a complex network that is based on information theory. The approach hinges on some recent results arising from the convergence between the theory of complex networks and probabilistic techniques for content mining. At its core there is the idea that nodes in a complex network correspond to basic information units from which links are extracted via methods of machine learning. Hence the links themselves are viewed as emergent properties, similarly to the broader structural properties mentioned above. Indeed, beside rounding up the theory, this approach based on learning has clear practical benefits, in that it makes networks emerge from arbitrary information domains. We provide examples and applications in a variety of contexts, starting from an information-theoretic reconstruction of the well-known distinction between “strong links” and “weak links” and then delving into specific applications such as business process management and analysis of policy making.

The concept of inreducible complexity is central to the origins controversy. Ineducible complexity (IC) may be defined as any machine or system that requires two or more parts in order to function. Examples range from molecules to mousetraps, organelles, and organisms such as humans. This essay explores the relationship between IC and complexity, clarifying the levels of IC such as the irreducible core and its mode of function. IC has been used in a wide variety of disciplines for over (...) a century. Objections to irreducibte complexity include co-option, the "junk DNA" theory, and the scaffolding argument. Co-option, a major argument against IC, attempts to explain how IC can be achieved through natural means by utilizing existing parts to construct a new biological machine or structure. Yet examples of IC in both the biological and non-biological wortds show that such common objections do not invalidate the concept. IC is firmly established. (shrink)

The last of Hume's five requirements of the ‘‘true judge in the finer arts’’, is that he be ‘‘cleared of all prejudice……'. I argue here that, lurking in this innocuous-sounding requirement of the true judge, is a complexity that reveals a significant tension in Hume's argument. It is that tension that I want briefly to explore.
