A persuasion dialogue is a dialogue in which a conflict between agents with respect to their points of view arises at the beginning of the talk and the agents have the shared, global goal of resolving the conflict and at least one agent has the persuasive aim to convince the other party to accept an opposing point of view. I argue that the persuasive force of argument may have not only extreme values but also intermediate strength. That is, I wish (...) to introduce two additional types of the effects of persuasion in addition to successful and unsuccessful ones (cf. Van Eemeren and Houtlosser in Argumentation 14(3):293–305, 2000; Advances in pragma-dialectics. Sic Sat, Amsterdam, 2002; Walton in A pragmatic theory of fallacy. University of Alabama Press, Tuscaloosa, 1995; Walton and Krabbe in Commitment in dialogue: basic concepts of interpersonal reasoning. State University of New York Press, Albany, New York, 1995). I propose a model which provides for modified versions of the standpoint of an agent needed in order to bring about two possible outcomes of a persuasion dialogue. These two outcomes I label partially-successful and over-successful. I call the potential, not yet verbalised, standpoint of an agent here the original topic t. Based on some aspects of relevance theory (Sperber and Wilson in Relevance: communication and cognition. Blackwell, Oxford, 1986; Wilson and Sperber in The handbook of pragmatics. Blackwell Publishing, Malden, 2006), I explain that the modified version of the original topic t is an implicature created from the original topic t and from a specific mental topic which belongs to, what I call the beneficial cognitive model (hence BCM). I define BCMi,t as a set of topics which are within the area of agent i’s interest of persuasion with respect to t. (shrink)

After more than 15 years of study, the 1/f noise or complex-systems approach to cognitive science has delivered promises of progress, colorful verbiage, and statistical analyses of phenomena whose relevance for cognition remains unclear. What the complex-systems approach has arguably failed to deliver are concrete insights about how people perceive, think, decide, and act. Without formal models that implement the proposed abstract concepts, the complex-systems approach to cognitive science runs the danger of becoming a philosophical exercise in futility. The complex-systems (...) approach can be informative and innovative, but only if it is implemented as a formal model that allows concrete prediction, falsification, and comparison against more traditional approaches.

Statistical topic models provide a general data - driven framework for automated discovery of high-level knowledge from large collections of text documents. Although topic models can potentially discover a broad range of themes in a data set, the interpretability of the learned topics is not always ideal. Human-defined concepts, however, tend to be semantically richer due to careful selection of words that define the concepts, but they may not span the themes in a data set exhaustively. In this study, we (...) review a new probabilistic framework for combining a hierarchy of human-defined semantic concepts with a statistical topic model to seek the best of both worlds. Results indicate that this combination leads to systematic improvements in generalization performance as well as enabling new techniques for inferring and visualizing the content of a document.

Scientists have used models for hundreds of years as a means of describing phenomena and as a basis for further analogy. In Scientific Models in Philosophy of Science, Daniela Bailer-Jones assembles an original and comprehensive philosophical analysis of how models have been used and interpreted in both historical and contemporary contexts. Bailer-Jones delineates the many forms models can take (ranging from equations to animals; from physical objects to theoretical constructs), and how they are put to use. She examines early mechanical (...) models employed by nineteenth-century physicists such as Kelvin and Maxwell, describes their roots in the mathematical principles of Newton and others, and compares them to contemporary mechanistic approaches. Bailer-Jones then views the use of analogy in the late nineteenth century as a means of understanding models and to link different branches of science. She reveals how analogies can also be models themselves, or can help to create them. The first half of the twentieth century saw little mention of models in the literature of logical empiricism. Focusing primarily on theory, logical empiricists believed that models were of temporary importance, flawed, and awaiting correction. The later contesting of logical empiricism, particularly the hypothetico-deductive account of theories, by philosophers such as Mary Hesse, sparked a renewed interest in the importance of models during the 1950s that continues to this day. Bailer-Jones analyzes subsequent propositions of: models as metaphors; Kuhn's concept of a paradigm; the Semantic View of theories; and the case study approaches of Cartwright and Morrison, among others. She then engages current debates on topics such as phenomena versus data, the distinctions between models and theories, the concepts of representation and realism, and the discerning of falsities in models.

This paper outlines the demographic characteristics of the Baiga tribe, one of the most primitive of the aboriginal tribal groups of Central India. The Baiga population has grown steadily since the first anthropological study of the tribe in the 1930s. Age at menarche, age at marriage, breast-feeding, and time interval between marriage and first conception are natural. There are more females than males. Sub-tribe endogamy is common; consanguineous marriage is favoured (34% of marriages are between first cousins) and marital distance (...) is low (mean 7·1 km). Though the mean menarcheal age is high (15·2 years), mean age at first marriage is low (16·6 years), giving a long reproductive period. (shrink)

Research on natural and artificial brains is proceeding at a rapid pace. However, the understanding of the essence of consciousness has changed slightly over the millennia, and only the last decade has brought some progress to the area. Scientific ideas emerged that the soul could be a product of the material body and that calculating machines could imitate brain processes. However, the authors of this book reject the previously common dualism—the view that the material and spiritual-psychic processes are separate and (...) require a completely different substance as their foundation. -/- Reductive Model of the Conscious Mind is a forward-thinking book wherein the authors identify processes that are the essence of conscious thinking and place them in the imagined, simplified structure of cells able to memorize and transmit information in the form of impulses, which they call neurons. The purpose of the study is to explain the essence of consciousness to the degree of development of natural sciences, because only the latter can find a way to embed the concept of the conscious mind in material brains. The book is divided into three parts. Part 1 works to convince readers that the emergence of consciousness does not require detailed knowledge of the structure and morphology of the brain, with the exception of some specific properties of the neural network structure that the authors attempt to point out. Part 2 proves that the biological structure of many natural brains fulfills the necessary conditions for consciousness and intelligent thinking. Similarly, Part 3 shows the ways in which artificial creatures imitating natural brains can meet these conditions, which gives great hopes for building artificially intelligent beings endowed with consciousness. Covering topics that include cognitive architecture, the embodied mind, and machine learning, this book is ideal for cognitive scientists, philosophers of mind, neuroscientists, psychologists, researchers, academicians, and advanced-level students. The book can also help to focus the research of linguists, neurologists, and biophysicists on the biophysical basis of postulated information processing into knowledge structures. (shrink)

In this paper we discuss a view of the Machine Learning technique called Explanation-Based Learning (EBL) or Explanation-Based Generalization (EBG) as a process for the interpretation of vague concepts in logic-based models of law.The open-textured nature of legal terms is a well-known open problem in the building of knowledge-based legal systems. EBG is a technique which creates generalizations of given examples on the basis of background domain knowledge. We relate these two topics by considering EBG''s domain knowledge as corresponding to (...) statute law rules, and EBG''s training example as corresponding to a precedent case. (shrink)

: This paper contains the analysis of nine interviews with UK scientists on the topic of scientific models. Scientific models are an important, very controversially discussed topic in philosophy of science. A reasonable expectation is that philosophical conceptions of models ought to be in agreement with scientific practice. Questioning practicing scientists on their use of and views on models provides material against which philosophical positions can be measured.

We generalize two concepts from special cases of Polish group actions to the general case. The two concepts are elementary embeddability, from model theory, and analytic sets, from the usual descriptive set theory.

“Critical thinking in higher education” is a phrase that means many things to many people. It is a broad church. Does it mean a propensity for finding fault? Does it refer to an analytical method? Does it mean an ethical attitude or a disposition? Does it mean all of the above? Educating to develop critical intellectuals and the Marxist concept of critical consciousness are very different from the logician’s toolkit of finding fallacies in passages of text, or the practice of (...) identifying and distinguishing valid from invalid syllogisms. Critical thinking in higher education can also encompass debates about critical pedagogy, i.e., political critiques of the role and function of education in society, critical feminist approaches to curriculum, issues related to what has become known as critical citizenship, or any other education-related topic that uses the appellation “critical”. Equally, it can, and usually does, refer to the importance and centrality of developing general skills in reasoning—skills that we hope all graduates possess. Yet, despite more than four decades of dedicated scholarly work “critical thinking” remains as elusive as ever. As a concept, it is, as Raymond Williams has noted, a ‘most difficult one’ (Williams, 1976, p. 74). (shrink)

This research works within the framework of constructivist learning (based on constructivist epistemology) and examines learning as an activity of construction, and it posits that knowledge acquisition (and learning) are transformative through self-involvement in some subject matter. Thus it leads, through this constructivism to a pedagogical theory of learning. I will mainly focus on conceptual and epistemological analysis of humans’ conceptualisations based on their own mental objects (schemata). Subsequently, I will propose an analytical specification of humans’ conceptualisations and understandings over (...) their mental structures in the framework of constructivism, and I will clarify my logical [and semantic] conceptions of humans’ concept understandings. This research focuses on the philosophy of education and on logics of human learning. It connects with the topics ‘Cognition in Education’ and ‘Mental Models’. (shrink)

There is a rapidly growing interest in the topic of sustainability as it relates to long‐term business performance that optimizes the “triple bottom line”: economic, environmental, and social outcomes. This article articulates a multilevel conceptual model for executing a business strategy for sustainability primarily through the design and implementation of human resource management practices. The model builds on open systems theory, the resource based view of the firm, and the concept of line of sight to identify certain key (...) organizational capabilities, group competencies, and individual abilities and other characteristics that combine to drive organizational performance when pursuing a sustainability strategy. The article concludes with a discussion of implications of the model for theory, research, and practice. (shrink)

Computational models of meaning trained on naturally occurring text successfully model human performance on tasks involving simple similarity measures, but they characterize meaning in terms of undifferentiated bags of words or topical dimensions. This has led some to question their psychological plausibility (Murphy, 2002;Schunn, 1999). We present here a fully automatic method for extracting a structured and comprehensive set of concept descriptions directly from an English part‐of‐speech‐tagged corpus. Concepts are characterized by weighted properties, enriched with concept–property types that approximate (...) classical relations such as hypernymy and function. Our model outperforms comparable algorithms in cognitive tasks pertaining not only to concept‐internal structures (discovering properties of concepts, grouping properties by property type) but also to inter‐concept relations (clustering into superordinates), suggesting the empirical validity of the property‐based approach.

What is it to share the same concept? The question is an important one since sharing the same concept explains our ability to non-accidentally coordinate on the same topic over time and between individuals. Moreover, concept identity grounds key logical relations among thought contents such as samesaying, contradiction, validity, and entailment. Finally, an account of concept identity is crucial to explaining and justifying epistemic efforts to better understand the precise contents of our thoughts. The key question, then, is what psychological (...) and social facts could play these roles? Elsewhere, we have argued for a specific relational model of concept identity, the connectedness model (e.g. Schroeter 2012, Schroeter and Schroeter 2014, 2015). Our aim in this chapter is to further explain the motivations behind that account, to address worries about transitivity and vagueness, and to contrast our approach with closely related accounts of concept identity developed by François Recanati and Simon Prosser. -/- What’s distinctive of our approach is that we seek to vindicate the first-person epistemic perspective of concept users. Concepts, on our account, play a crucial normative role in setting regulative ideals for the representational practices in which individual subjects participate. This focus on the normative role of concepts – as opposed to a purely causal explanatory role – motivates our approach to concept identity and our toleration of vagueness and borderline cases.

Clinical musings on the nature of reality and "known experience." Therapists must rely on their clients' reporting of experience in order to assess, treat, and offer help. Yet we all experience the world through various filters of one sort or another, and our experiences are transformed through several nonconscious processes before reaching our conscious awareness. Science, philosophy, and wisdom traditions share the belief that our awareness is very restricted. How, then, can anyone accurately report their experience, let alone get help (...) with it? Neuropsychologist Aldrich Chan examines how our experience of reality is assembled and shaped by biological, psychological, sociocultural, and existential processes. Each chapter explores processes within these domains that may act as "veils." Topics in the book include: the default mode network, cognitive distortions, decision-making heuristics, the interconnected mind, memory, and cultural concepts of distress. By understanding the ways in which reality can be distorted, clinicians can more effectively help their clients reach their personal psychotherapeutic goals. (shrink)

Critique involves reflection, specifically self-reflection, and as such it is inherently linked with philosophy. Critique calls for change, awareness, liberation from false conceptions, and reshaping of spheres of action and belief. Consequently it is closely linked with the moral and the political. Critique aspires to enhance truth, beauty, and justice and is thus an integral part of science, art, and social action. The present volume tackles issues of critique through a selection of papers originally presented at the workshop on “Models (...) of Critique in the Sciences, Society, and the Arts,” held in Jerusalem and Tel Aviv during May 1996. As the full program indicates, this selection provides only a partial picture of the topics discussed at the workshop. A major consideration has been the publication policy of Science in Context, with its emphasis on science, which is reflected here. We wish to express our gratitude to all the participants for their presentations and contributions to a stimulating exchange of ideas. (shrink)

Questions about the structure and justification of theories, the interpretation of data, and the problem of realism have been in the forefront of debate in recent philosophy of science, and the topic of models and analogies is increasingly recognized as integral to this debate. Models of physical matter and motion ‐ for example, models of atoms and planetary systems ‐ were already familiar in Greek science, but serious analysis of “model” as a concept entered philosophy of science only in (...) the nineteenth century. This was largely the result of proliferation in classical physics of theoretical entities such as “atom,” “electro‐magnetic wave,” and “electron,” for which there appeared to be no directly observable evidence (see theoretical terms).

Thick moral concepts are a topic of particular disagreement in discussions of reasons holism. These concepts, such as justice, are called “thick” because they have both evaluative and descriptive aspects. Thin moral concepts, such as good, are purely evaluative. The disagreement concerns whether the fact that an action is, for example, just always a reason in favor of performing that action. The present argument follows Jonathan Dancy’s strategy of connecting moral reasons and concepts to those in other domains. If Dancy (...) is correct then we should expect holism about thick moral concepts to the same extent to which we find holism for other sorts of thick concepts. Using this strategy two claims are defended: that reasons holism is characteristic of non-moral thick concepts—specifically, of aesthetic, epistemic and prudential thick concepts—and that such non-moral concepts exemplify useful and heretofore unnoticed models for thick moral concepts.

The broad topic of this paper is the relationship between the theoretical notion of a concept and familiar types of cognitive structures (prototypes, exemplars, causal models, etc.) The discussion is organized around different ways that theorists about concepts can attempt to accommodate what has been dubbed the Heterogeneity Hypothesis (roughly: the claim that various types of structures with which concepts have been identified co-exist and form a heterogeneous class). The most general goal of the paper is to clarify the dialectical (...) geography when it comes to different ways of construing the relationship between concepts and familiar cognitive structures. A more focussed and more polemical goal of the paper is to raise problems for so-called pluralist approaches to concepts. This paper will not offer a comprehensive defense of any particular view about the relationship between concepts and cognitive structures, but the discussion will be a convenient venue in which to highlight some virtues of what I will call Higher-Level Unity approaches to concepts.

This unique volume introduces and discusses the methods of validating computer simulations in scientific research. The core concepts, strategies, and techniques of validation are explained by an international team of pre-eminent authorities, drawing on expertise from various fields ranging from engineering and the physical sciences to the social sciences and history. The work also offers new and original philosophical perspectives on the validation of simulations. Topics and features: introduces the fundamental concepts and principles related to the validation of computer simulations, (...) and examines philosophical frameworks for thinking about validation; provides an overview of the various strategies and techniques available for validating simulations, as well as the preparatory steps that have to be taken prior to validation; describes commonly used reference points and mathematical frameworks applicable to simulation validation; reviews the legal prescriptions, and the administrative and procedural activities related to simulation validation; presents examples of best practice that demonstrate how methods of validation are applied in various disciplines and with different types of simulation models; covers important practical challenges faced by simulation scientists when applying validation methods and techniques; offers a selection of general philosophical reflections that explore the significance of validation from a broader perspective. This truly interdisciplinary handbook will appeal to a broad audience, from professional scientists spanning all natural and social sciences, to young scholars new to research with computer simulations. Philosophers of science, and methodologists seeking to increase their understanding of simulation validation, will also find much to benefit from in the text. (shrink)

The topic of this thesis is the nature of human concepts understood as mental symbols or representations. ;Many discussions in this area presuppose an inferential model of concepts taken together with what I call the standard model of concept learning. An inferential model of concepts says that a concept's identity depends upon its participating in inferential dispositions linking it to certain other concepts. For example, one might think that part of what makes a mental symbol the concept (...) BIRD is that it participates in an inferential disposition linking it to the concept ANIMAL. The standard model of concept learning says that learning a concept involves assembling it from previously available concepts. For example, one might think that the concept BIRD is learned by putting together the concept ANIMAL with concepts like WING, FLIES, and so on, yielding a more complex structure. The standard model of concept learning presupposes a form of the inferential model of concepts. Thus one of the reasons many people endorse the inferential model is that they are committed to a broadly empiricist picture of the mind; they assume that most concepts are learned, so they must also assume that most concepts have the sort of structure that the model presupposes. ;My thesis challenges both of these points with respect to a class of concept that has been of central interest in philosophy and cognitive science, namely, the lexical concepts . I argue that the independent evidence for the inferential model in this case is no good and consequently that the standard model of concept learning doesn't work. Still, it remains plausible that many lexical concepts are learned. What we need are new learning models, ones that depart in significant ways from the standard model. I end the thesis by outlining a proposal that may work for the natural kind concepts. (shrink)

The first sophisticated wargames were developed between 1770 and 1830 and are models of military conflict. Designers of these early games experimented fruitfully with different concepts that were formulated in interaction with the external dynamics of the military systems that they tried to represent and the internal dynamics of the design process itself. The designers of early wargames were confronted with a problem that affects all models: the trade-off between realism and simplicity, which in the case of wargames amounts to (...) the trade-off between realism and playability. I try to show how different game concepts were developed as an answer to this problem, and how these seemingly arcane concepts form a relevant topic of investigation in the history of ideas. Moreover, a direct offshoot of this conceptual experimentation between 1770 and 1830 was the ‘free’ German wargame, which became an integral part of German operational planning in the nineteenth and twentieth centuries, thus adding another chapter to the story of the influence of ideas on human history.

This paper argues for a reinterpretation of Aristotle's concept of an enthymeme and also his wider informal logic in terms of arguments that are defeasible. They are represented by forms of argument that are called argumentation schemes, considered to be similar to forms of argument found in deductive logic, but different from the foregoing in virtue of their being defeasible. Indeed, the most interesting schemes have been put forward as a helpful way of characterizing structures of human reasoning that have (...) proved troublesome to model deductively. The paper sheds new light on Aristotle's topics and how to dene `enthymeme'. If the traditional denition of an enthymeme in logic accepted for over two thousand years is a misnomer, the question is raised whether we ought to redene it as a defeasible argumentations scheme or leave things as they are.

The subject of the research is a modern graphic and communicative design, in the context of changing existing and forming new roles of communicators, transforming the communication model, forming a semiotic communication format. The object of the research is modern graphic and communicative design, as well as their traditional, digital and generative subdirections. Design beginning to have digital, semiotic-interactive and artificially intelligent characteristics. The author examines in detail such aspects of the topic as: dialogical, semiotic-interactive qualities of design solutions; (...) digital, semiotic-interactive design-software expressive means; features of semiotic-deconstructivity (analyticity) and semiotic-synthetics (constructiveness) of design solutions in the context of design activity; the influence of technical and technological features of tools and design-environments (design systems) for the formation of automated and artificially intelligent qualities of design solutions. The study of the conceptual model of a semiotic-interactive design is carried out in the context of a semiotic-interactive methodology (a set of principles and strategies of design activity). The main conclusions of the study are the description of the conceptual model of a semiotic-interactive design solution, in the context of a semiotic-interactive methodology implemented in the conceptual-generative subdirection of modern graphic and communicative design. The author's main contribution to the research of the topic is to identify the main components of the conceptual model of a semiotic-interactive design solution and demonstrate their relationship with each other in the form of a holistic model. The novelty of the research lies in the description of the characteristics of the components, the conceptual model of a semiotic-interactive design solution: a dialogical semiotic-interactive format for creating invariant concepts and design solutions; versioning of design solutions based on the semiotic synthesis of design programs; semiotic deconstruction of design solutions at the macro and micro levels; semiotic synthesis of design and artistic design programs; application of design programs as decision tools; use of hyperconnected capabilities of the design environment: the history of actions, integrity and continuous change and development.

Metaphors are cognitive and linguistic tools that allow reasoning. They enable the understanding of abstract domains via elements borrowed from concrete ones. The underlying mechanism in metaphorical mapping is the manipulation of concepts. This article proposes another view on what concepts are and their role in metaphor and reasoning. That is, based on current neuroscientific and behavioural evidence, it is argued that concepts are grounded in perceptual and motor experience with physical and social environments. This definition of concepts is then (...) embedded in the Structure-Mapping Theory, a model for metaphorical processing and reasoning. The blended view of structure-mapping and embodied cognition offers an insight into the processes through which the target domain of a metaphor is embodied or realised in terms of its base domain. The implications of the proposed embodied SMT model are then discussed and future topics of investigation are outlined. (shrink)

Understanding the 'making-up' relations, to put things neutrally, posited in mechanistic explanations the sciences is finally an explicit topic of debate amongst philosophers of science. In particular, there is now lively debate over the nature of the so-called 'realization' relations between properties posited in such explanations. Despite criticism (Gillett, Analysis 62: 316-323, 2002a), the most common approach continues to be that of applying machinery developed in the philosophy of mind to scientific concepts in what is known as the 'Flat' or (...) 'Subset' model of 'realization' (Kim, Mind in a physical world, 1998; Shapiro, J Philos XCVII: 635-654, 2000; Clapp, J Philos XCVIII: 111-136,2001 ; Wilson, Philos Stud 145: 149-169,2009). My primary goal in this paper is to show in still more detail that the Subset model of realization is inadequate for the descriptive task of describing the 'making-up' relations posited between properties or their instances in mechanistic explanations in the higher sciences. And my secondary goal is to highlight why this critique of the Subset view as a first-order descriptive account also shows there are deep difficulties in using the Subset account to address second-order issues in the philosophy of science as well.

Nowadays “philosophy of biology” is taken to be the special study of a set of issues concerning selection, adaptation, and the characterization of a species. Though the reduction of biology to chemistry and physics remained a topic in the general philosophy of science syllabus through the 1970s, the concept of life subsequently lost even this marginal foothold in the curriculum.

Taking as starting point Kuhn’s analysis of science textbooks and its application to Sinnott and Dunn’s (1925), it will be discussed the problem of the existence of laws in biology. In particular, it will be showed, in accordance with the proposals of Darden (1991) and Schaffner (1980, 1986, 1993), the relevance of the exemplars, diagrammatically or graphically represented, in the way in which is carried out the teaching and learning process of classical genetics, inasmuch as the information contained in them, (...) indispensable for the right development of that process, exceeds the information contained in the “laws” linguistically articulated and presented in the textbooks. However, it will be maintained that the information is implicit in the law that according to the structuralist concept of fundamental law and the reconstruction of genetics presented by Balzer & Dawe (1990), and later developed by Balzer & Lorenzano (1997) and Lorenzano (1995, 2000, 2002a) could be considered the fundamental law of classical genetics,the law of matching, clearly identified in this paper.

Over the past few decades, cognitive science has identified several forms of reasoning that make essential use of conceptual knowledge. Despite significant theoretical and empirical progress, there is still no unified framework for understanding how concepts are used in reasoning. This paper argues that the theory of conceptual spaces is capable of filling this gap. Our strategy is to demonstrate how various inference mechanisms which clearly rely on conceptual information—including similarity, typicality, and diagnosticity-based reasoning—can be modeled using principles derived from (...) conceptual spaces. Our first topic analyzes the role of expectations in inductive reasoning and their relation to the structure of our concepts. We examine the relationship between using generic expressions in natural language and common-sense reasoning as a second topic. We propose that the strength of a generic can be described by distances between properties and prototypes in conceptual spaces. Our third topic is category-based induction. We demonstrate that the theory of conceptual spaces can serve as a comprehensive model for this type of reasoning. The final topic is analogy. We review some proposals in this area, present a taxonomy of analogical relations, and show how to model them in terms of distances in conceptual spaces. We also briefly discuss the implications of the model for reasoning with concepts in artificial systems. (shrink)

This paper is an attempt to advances research on walking, at a neighbourhood level of analysis for people with disabilities, by proposing a theoretical model that combines the knowledge of two disciplines: traffic planning and environmental psychology. The aim is to provide a guidance for a discussion and a planning of future interdisciplinary investigations, by proposing a model that accounts for the dynamic interaction between environmental characteristics, human processes, and walking experience among individuals with a disability. For this (...) purpose, traffic planners and environmental psychologists came together to discuss theories, concepts, and thematic of relevance in a series of focus group meetings. These meetings led to the selection of the Human Environment Interaction (HEI) model, originally developed from the field of environmental psychology, and operationalised to describe how walking experiences result from the interplay between individual abilities, emotional processes and physical and social characteristics of the environment (Küller, 1991). The proposed model aims to sustain interdisciplinary discussion and research planning around the topic of neighbourhood walking for people with disabilities. By operationalising each dimension in the model, a good fit between groups with disabilities and individual differences associated with walking experiences is assumed, which in turn will have the potential to provide a more conscious analysis of wellbeing-related outcomes such as, usability of the environment, frequency of mobility, and quality of life. However, to improve understanding of urban walking at a neighbourhood level for people with disabilities, empirical studies must be carried out to test the proposed model. (shrink)

In order to secure the limits of the critical use of reason, and to succeed in the critique of speculative metaphysics, Immanuel Kant (1724–1804) had to present a full account of human cognitive experience. Perception in Kant’s Model of Experience is a detailed investigation of this aspect of Kant’s grand enterprise with a special focus: perception. The overarching goal is to understand this common phenomenon both in itself and as the key to understanding Kant’s views of experience. In the (...) process, the author argues against any such reading of Kant that puts too much emphasis on concepts and understanding in perception. This means that claims of the sort that intuitions cannot play their role without concepts, that sensibility cannot bring anything to cognition without being mediated through the functions of understanding, or that there is no such thing as concept-independent perception, are shown to be either plainly false or misleading at best. Together with the contemporary topics examined by the end of the book, the findings suggest how the role of conceptual thinking in human cognition has been exaggerated partly because of a misplaced interpretation of Kant, which not only makes perception far more intellectual in character than what was intended by Kant himself, but distorts Kant’s account of cognition by overlooking what there is at the heart of his critical philosophy: the revaluation of sensible cognition.

We present a neural dynamic model that perceptually grounds nested noun phrases, that is, noun phrases that contain further (possibly also nested) noun phrases as parts. The model receives input from the visual array and a representation of a noun phrase from language processing. It organizes a search for the denoted object in the visual scene. The model is a neural dynamic architecture of interacting neural populations which has clear interfaces with perceptual processes. It solves a set (...) of theoretical challenges, including the problem of keeping a nested structure in short-term memory in a way that solves the problem of 2 and massive binding problem emphasized by Jackendoff. The model organizes a search for the objects that are referenced in that structure. We motivate the model, demonstrate simulation results, and discuss how it differs from related models. (shrink)

The ways in which Wittgenstein was directly influenced by William James (by his early psychological work as well his later philosophy) have been thoroughly explored and charted by Russell B. Goodman. In particular, Goodman has drawn attention to the pragmatist resonances of the Wittgensteinian notion of hinge propositions as developedand articulated in the posthumously edited and published work, On Certainty. This paper attempts to extend Goodman’s observation, moving beyond his focus on James (specifically, James’s Pragmatism) as his pragmatist reference point. (...) It aims to articulate the affinity between Wittgenstein’s thought on the topic of certainty and that of the neglected pragmatist thinker, George Santayana. -/- The paper draws on Duncan Pritchard’s recent reading of Wittgenstein’s On Certainty in order to articulate the concept of certainty involved in the notion of hinge propositions. It identifies two important and related points of affinity between this Wittgensteinian line of thought on certainty and the line of thought on the same topic articulated in Santayana’s Scepticism and Animal Faith. The paper argues, firstly, that, both lines of thought reflect a pragmatist concept of certainty, according to which our most fundamental certainties are not conceived as purely theoretical objects of belief or knowledge but rather as thearational presuppositions of beliefs and practical action. Secondly, it examines the way inwhich the pragmatist concept of certainty functions, for the two thinkers as a response to scepticism. It argues that although the two thinkers’ responses are very different, they are mutually compatible and, together, point towards the possibility of a distinctively pragmatist response to scepticism, which involves an anti-epistemological model of the intimate relation of the human self to the world.

The chief topics discussed in this carefully written book are the nature of definitions in science, the distinction between observational and theoretical terms, changes in scientific concepts and the role of analogies and models in science. The unifying theme is that of meaning in the sciences. Its treatment by Achinstein indicates a trend in recent philosophy of science toward finding a middle ground between two antithetical positions on the topic of the meaning of scientific terms. On the one side stands (...) the traditional positivist and logical empiricist account which distinguishes sharply between the meaning of observational and theoretical terms, and on the other side, the more recent views of Feyerabend, Kuhn, Hanson, Toulmin and others who stress the dependence of the meaning of observational terms on that of theoretical terms and the change of meaning of all terms connected with a theory when the theory changes. Achinstein argues cogently that the extreme versions of these positions will not work. Their main problem is that their treatment of meaning is too rigid and monolithic. His own discussion of meaning in the early chapters on definition bristles with distinctions, nuances, and concrete examples from the sciences. In terms of the distinctions of this part of the book he is later able to argue against Feyerabend and Kuhn that in changes of scientific concepts such as characterize scientific revolutions not all of the meaning connections of the various terms need be altered. He also argues that of the many ways proposed to distinguish between theoretical and observational terms, no one is fundamental, though each may be relevant to certain categories of questions one might want to raise about scientific terms. This book thus leads away from the simpler doctrinal statements of the past about the meaning of scientific terms toward a theory of meaning requiring more distinctions, qualifications, nuances, and more subtlety all around.--R.

Terms for consciousness, used with a cognitive meaning, emerged as count nouns in the 17th century. This transformation repeats an evolution that had taken place in late antiquity, when related vocabulary, used in the sense of conscience, went from being mass nouns designating states to count nouns designating faculties possessed by every individual. The reified concept of consciousness resulted from the rejection of the Scholastic-Aristotelian theory of mind according to which the mind is not a countable thing, but a pure (...) potentiality. This rejection was motivated by an acute sense of the mind’s fallible subjectivity. While conditioned by recent historical events, the 17th century’s pervasive sense of subjectivity also reveals a heavy debt to Hellenistic philosophy, which had been recently rediscovered. But whereas Hellenistic thought, mistrustful of theoria, only reifies conscience, early modern thinking, more mistrustful of praxis and seeking its grounding in theoria, goes a step further and reifies consciousness. Partly modeled on theological ideas, the resulting concept of consciousness is plagued by paradoxes that have becomes notorious for their intractability. But essentially the same model of consciousness underwrites contemporary theory, embroiling contemporary debates in the same controversies that dominated the 17th century. Sidestepping these difficulties by returning to the Scholastic-Aristotelian theory of mind would be a tall order, but it is not impossible. Alfred North Whitehead's theory of consciousness offers an example. His novel theory of time enables Whitehead to rehabilitate the Aristotelian concept of passive mind in a wholly naturalistic way.

An enlargement of a previous work by the author, this work is intended as a reference source for study in the theory of models of logical systems, and as a textbook; the latter aim is reached by including numerous problems, many of them of a high level of difficulty, at the end of each chapter. The sections deal with, respectively, the lower predicate calculus, the structure of algebraic theories, concepts from model theory, completeness of various systems, definability of concepts, (...) generalizations of algebraic concepts, the metamathematical theories of ideals and varieties, and various selected topics including non-standard analysis. Unfortunately, there are numerous misprints which mar an otherwise excellent presentation. Much of the material presented is new, or is presented in new form. Robinson's approach is mildly idiosyncratic and often at variance with more conventional presentations, and this may make for difficulty in relating it to these presentations. Nevertheless, for the reader with a working knowledge of algebra and no small perseverance, this book will be rewarding.—P. J. M. (shrink)

The topic of this dissertation is what thought must be like in order for the laws and generalizations of psychology to be true. I address a number of contemporary problems in the philosophy of mind concerning the nature and structure of concepts and the ontological status of mental content. Drawing on empirical work in psychology, I develop a number of new conceptual tools for theorizing about concepts, including a counterpart model of concepts' role in linguistic communication, and a deflationary (...) theory of concepts' formal features. I also suggest some new answers to old problems, arguing, for example, that content realism is not hostage to a naturalized semantics. This dissertation can, as a whole, be read as a sympathetic re-evaluation of the language of thought hypothesis (LOT). LOT claims that thoughts are sentences in a mental language of computation, and are composed of meaningful, atomic symbols—concepts—which are individuated entirely by their formal features. Each chapter either defends various components of LOT from recent criticism, or fills in gaps in the theory. I begin the dissertation by introducing the language of thought project, and motivating and explaining each of its central components. In chapter 2, I discuss a recent competitor to atomism—neo-empiricism—and argue that it fails to meet several key desiderata on theories of concepts, and defend atomism from similar charges. In chapter 3, I argue against a view common to both philosophy and psychology: that concepts must be shareable. If true, atomism is in jeopardy. I find shareability to be unmotivated, and suggest an alternative counterpart model of concepts that does a better job of explaining the things shareability was supposed to explain. Chapter 4 takes up the question of what formal features are and how mental symbols are individuated. I develop a reductive account, arguing that formal features are certain sorts of physical properties and symbol types are sets of these properties. I turn to the topic of content in chapter 5, and defend a very strong version of content realism against recent criticism. (shrink)

This paper means to demonstrate the theoretical-and- methodological potential of a particular pattern of thought about culture. Employing an end-means and absolute value plus concept of reality approach, the continuous model of culture aims to embrace from one holistic standpoint various concepts and debates of the modern human, social, and political sciences. The paper revisits the debates of fact versus value, nature versus culture, culture versus structure, agency versus structure, and economics versus politics and offers the concepts of the (...) rule of law, state capitalism, a dialectical model of progress, and interpretative qualitative research, as well as of cultural diffusion, autonomy, alienation, and individuality. This model distinguishes between the ideal-symbolical and the instrumental functions of culture, sees culture as being sewn from universal binaries, and provides a certain understanding of the cognitive function of a value judgment, with positivism so far vague about the topic. It, too, suggests an extra method for investigating culture : the comparative literature study of culture enables social science to view literature as its potential in-depth interviewee— a case for arguing for a certain conception of interdisciplinarity as well. In addition, it predicts that cultural particularism or individuality remains an essential factor of human existence. Analyzing the issue of Eurocentrism in social science, the model finds modernity ’s concept of reality to be involved in ” methodological ” intellectualistic reductionism, characterizing it since the empiricism/ rationalism origination. Systematically confusing the universal oppositions in a Eurocentric manner, intellectualism becomes a contributing factor in unfolding post- modernity. (shrink)

After the death of Prophet Muhammad (p.b.u.h), one of the most significant debated topics of Muslims was the institution of caliphate. This institution caused crucial argumentations through the ages from Abu Bakr to Abd-al-Majid who was the hundreth khalifa. Some prominent issues in that regard as follows: How khalifa comes to power, who becomes khalifa, whether he is descended from Quraysh or not, which kind of traits khalifa should have, and how khalifa should behave in certain circumstances. While these arguments (...) were going on, caliphate was maintained based on the reign under some certain dynasties’ responsibilities after the Rashidun (rightly guided) Caliphs. Umayyads, Abbasids and Ottoman Dynasties were the most well-known ones of these dynasties. Throughout history, even though caliphate passed in one another’s hands among aforementioned dynasties, none of them did attempt to abolish this position. However, Turkish Muslims who became defeated with European occupation of non-western territories decided to abolish caliphate for the sake of modernization activities within the period of transition from imperialism to nation state. This decision brought about a trauma, which was much more critical than former argumentation around the position in Muslim world. Many congresses were organized in Islamic world in order to recover from this trauma. While this kind of quests were continuing, Muhammad Hamīdullah proposed “High Caliphate Council” in relation to rearrangement of caliphate in accordance with the conditions of Islamic countries. This proposal offers an applicable model to today’s modern nation states by establishing unity among them and leaving aside their conflicts and differences. This proposal offers a resolution of much-discussed matters of the position within the limits of principals. It also draws attention by showing a possibility of Islamic union in contemporary Islamic thought. Summary: The matters of who undertakes the management of societies, how rulers come to power and in what manners the rulers maintain the management have been discussed throughout history. It is seen that rulers adopted kingdom as regime before the period of the Prophet Muhammad (p.b.u.h). There was also two-person management. The discussions about this matter were also seen around khalifas who were the rulers of Muslims after the death of Prophet Muhammad (p.b.u.h). Some debated issues in that regards as follows: Who becomes khalifa, how he is elected, which traits he should possess, and so on. Caliphate continued its existence despite the discussions until the first quarter of the 14th Hijra era. Abolition of caliphate was a trauma for Muslims undoubtedly. From Anatolia to Egypt and from India to the Balkans, many attempts were carried out to recover from this trauma. However, this matter was oversimplified in the conditions of that period since it became a topic which was hushed over in just congresses and conventions. One of the people who wrote on this topic, which maintains its vitality even today was Muhammad Hamīdullah. He was an important Islamic scholar, a lawyer and a historian in Indian geography. Hamīdullah did deal caliphate by indicating its history broadly. The distinctive feature of Hamīdullah from others who wrote on this topic is that he also presented a considerable offer to solve the matter. In this sense, Hamīdullah experienced the trauma in his own life as all muslims did it with the abolition of caliphate. Hence he mentioned this matter in his writings in the mood of care and dignity of a scientist and also in feeling of a heartbroken muslim. Hamīdullah made clear that the method of election of the ruler differed throughout history. Indeed, the verses of Holy Qur’ān, the applications of the Prophet Muhammad (p.b.u.h) and the differences of Four Great Chaliphs on coming to power testified this claim. According to Hamīdullah, it is quite normal that the method of regime can vary according to the conditions of societies. He recommended acting based on timeless rules rather than the changes that vary according to conditions and places. He also stated that the regime which Islam approves is a combination of kingdom and democracy in his lines dealing with methods of regime. To him, kingdom is the method of regime of empire. Empire is the regime in which various nationalities live together with all their differences and interact with one another intensely and in which the rulers rule over wide borders. On the other hand, Islamic world lost its edges of empire, changed its regime and divided to nation states after the decline of the Ottoman Empire and Mughal Empire which were established by Muslims. On the contrary, westerners attempted to establish a head empire several times after building nation states in Europe. Some of them are UN, NATO, EU, to name but a few. In our opinion, in the transition process of Muslim rulers from empire to nation state, Hamīdullah made an offer to accomodate Islamic law in state law, Islamic politic and administrative principles in politics and administration practices, Islamic education system in education system, and principles of Islamic economics in economic decisions of government using the Prophet Muhammed’s life as a base. He also explained to Muslims that the method of regime can be changed and the essential matter is to apply Islamic management principles in such a new situation. He played a role in clearing the way for Muslims by indicating that the method of Islamic regime can be changed according to conditions but the principles of Islam are unalterable. To the writer of these lines, Hamīdullah intimates that it is not so true to stick to the form of the process in Muslim territories in which a compulsory transition from the empires or multinational social structures to the nation state structures have been experienced for the last two ages. However, the first matter to dwell on should be whether the ruler of the government behaves in accoradance with the principles of Islam or not. To Hamīdullah, the second matter is that even though Muslim countries had to enter in the process of becoming nation states, Muslims should make an effort to establish supra-state associations as required by Islam. In this respect, Hamīdullah’s proposal is “High Caliphate Council”. This council is a considerable offer presented to Muslim countries in the age when a universal caliphate is not possible and Muslims head towards a unified state form all over the world. Today, this offer recommends countries of which great majority is Muslims and in which Muslims are minority to meet on a common ground rather than conflict because of differences among them. The High Caliphate Council is an institute consists of presidents or hereditary administrators as leading and regular members and so it avoids regional competition. It is established by Muslim presidents who shares the chair alternately. Based on this, all Muslim presidents play a role altogether in this council without need to be Sunni, Shia, or from Quraysh. The High Caliphate Council is a reflection of a dream, which started a century and half a century ago but is required more today. It is also a reflection of the discourse of “Islamic Union” in Contemporary Islamic Thought. The Caliphate Council and International Islamic Legists’ Association, which is the first practical step of the council can be seen as the theory of a new world order based on the unity principle of Islam. Hamīdullah does not consider this order not only in the range of belief but also with the aim of institutionalizing ‘ijmā (consensus of Islamic legists) and qiyās(legal analogy). He stated that International Islamic Legists’ Association, which is a scientific institution could not be established beforetime by Muslims spread on three continents due to lacking of communication among them. However, thanks to today’s possibilities, the establishment of such association is easier today. Hamīdullah found dynamic solutions such these two institutions for the realization of caliphate, which is a religious necessity. He marked an era for Muslims in the period of time when they are on a quest. (shrink)

The introductory personal remarks refer to my motivations for choosing research projects, and for moving from physics to molecular biology and then to development, with Hydra as a model system. Historically, Trembley’s discovery of Hydra regeneration in 1744 was the begin¬ning of developmental biology as we understand it, with passionate debates about preformation versus de novo generation, mechanisms versus organisms. In fact, seemingly conflicting bottom-up and top-down concepts are both required in combination to understand development. In modern terms, this (...) means analysing the molecules involved, as well as searching for physical principles underlying development within systems of molecules, cells and tissues. During the last decade, molecular biology has provided surprising and impressive evidence that the same types of mol¬ecules and molecular systems are involved in pattern formation in a wide range of organisms, including coelenterates like Hydra, and thus appear to have been “invented” early in evolution. Likewise, the features of certain systems, especially those of developmental regulation, are found in many different organisms. This includes the generation of spatial structures by the interplay of self-enhancing activation and “lateral” inhibitory effects of wider range, which is a main topic of my essay. Hydra regeneration is a particularly clear model for the formation of defined patterns within initially near-uniform tissues. In conclusion, this essay emphasizes the analysis of development in terms of physical laws, including the application of mathematics, and insists that Hydra was, and will continue to be, a rewarding model for understanding general features of embryogenesis and regeneration. -/- -/- .
