In this work Ockham proposes a theory of simple predication, which he uses in explicating the truth conditions of progressively more complicated kinds of propositions. His discussion includes what he takes to be the correct semantic treatment of quantified propositions, past tense and future tense propositions, and modal propositions, all of which are receiving much attention from contemporary philosophers. He also illustrates the use of exponential analysis to deal with propositions that prove troublesome in both semantic theory and (...) other disciplines, such as metaphysics, physics, and theology. This type of analysis plays an essential role in his substantive philosophical and theological works, and in many cases then can hardly be understood without a prior acquaintance with this section of the Summa. An introduction by Alfred J. Freddoso clarifies and summarizes Ockham's theory, discusses certain philosophical problems which it engenders, and proposes new interpretations for parts of it. The essay will be helpful both to those interested in Ockham as a historical figure and to those interested in his substantive systematic contributions to logical theory. (shrink)

The most remarkable fact about the universe is that certain parts of it are conscious. Somehow nature has managed to pull the rabbit of experience out of a hat made of mere matter. Making its own contribution to the current, lively debate about the nature of consciousness, Theories of Consciousness introduces variety of approaches to consciousness and explores to what extent scientific understanding of consciousness is possible. Including discussion of key figures, such as Descartes, Foder, Dennett and Chalmers, the book (...) covers identity theories, representational theories, intentionality, externalism, and the new information-based theories.

The present article locates the figurative character of the hermeneutics in the thinking of Neitzsche. For this, it is necessary to have a particular perspective that makes a character (a real, literary, historical or philosophical one, etc.) a figure of interpretation that neither shows things metaphysically nor it is directed towards them by means of a phenomena. Instead, it revives them symbolically, inspiring a new wave of hermeneutics for interpretation and a new angle for comprehension. The main function is its (...) relatedness as a background on which the imperceptible connection stands out. That makes a hermeneutic figure the center or an axis of vibrations that move its discursive and critical components, crossing with impertinence the boundaries of the interpreted and the imaginary.

Kant’s early work The False Subtlety of the Four Syllogistic Figures is typically considered a narrow, technical work still embedded in the tradition of Wolffian logic. I argue instead that it needs to be considered in light of Kant’s developing theory of cognition and his corresponding criticism of the Wolffian single faculty theory. Whereas the mature Kant criticizes the rationalists for misrepresenting the nature of sensibility, the urgent task facing him at this stage seems to have been a (...) proper determination of the nature of the understanding. On the Wolffian framework, the latter is defined in a merely nominal manner, in terms of a generic cognitive task: the distinct representation of the possible. On Kant’s view, however, distinctness entails a capacity to relate representations, which only happens in the act of judgment. Thus, the stated aim of the False Subtlety notwithstanding, the work attempts to reorganize the logical operations around the capacity to judge. In turn, by defining the higher faculty of cognition in terms of an act of relating representations, Kant wants to show that this faculty cannot stem from a power of representation that we share with non-rational animals and must instead rest on a different fundamental power, which at the time he alternatively calls “inner sense” or “consciousness”.

In this case report, we studied Theory of Mind and figurative language comprehension in a 7.2-year-old child, conventionally named RJ, with isolated and complete agenesis of the corpus callosum, a rare malformation due to the absence of the corpus callosum, the major tract connecting the two brain hemispheres. To study ToM, which is the capability to infer the other’s mental states, we used the classical false belief tasks, and to study figurative language, i.e., those linguistic usages involving non-literal meanings, (...) we used tasks assessing metaphor and idiom comprehension. RJ’s intellectual level and his phonological, lexical, and grammatical abilities were all adequate. In both the ToM false belief tasks and novel sensory metaphor comprehension, RJ showed a delay of 3 years and a significant gap compared to a typically developing control group, while in idioms, his performance was at the border of average. These outcomes suggest that RJ has a specific pragmatic difficulty in all tasks where he must interpret the other’s communicative intention, as in ToM tasks and novel sensory metaphor comprehension. The outcomes also open up interesting insights into the relationships between ToM and figurative language in children with isolated and complete ACC. (shrink)

The term 'systems theory' is used to characterize a set of disparate yet related approaches to fields as varied as information theory, cybernetics, biology, sociology, history, literature, and philosophy. What unites each of these traditions of systems theory is a shared focus on general features of systems and their fundamental importance for diverse areas of life. Yet there are considerable differences among these traditions, and each tradition has developed its own methodologies, journals, and forms of anaylsis. This (...) book explores this terrain and provides an overview of and guide to the traditions of systems theory in their considerable variety. The book draws attention to the traditions of systems theory in their historical development, especially as related to the humanities and social sciences, and shows how from these traditions various contemporary developments have ensued. It provides a guide for strains of thought that are key to understanding 20th century intellectual life in many areas. (shrink)

Theories of Consciousness provides an introduction to a variety of approaches to consciousness, questions the nature of consciousness, and contributes to current debates about whether a scientific understanding of consciousness is possible. While discussing key figures including Descartes, Fodor, Dennett and Chalmers, the book incorporates identity theories, representational theories, intentionality, externalism and new information-based theories.

We can make a good prima facie case for the inconsistency of Reid's theory of perception with his rejection of the Ideal Theory. Most scholars believe Reid adopts a theory on which the immediate object of perception is a physical body. Reid is thought to do this in order to avoid problems generated by the veil of perception in the Ideal Theory, a conjunction of commitments Reid closely associates with Hume and Locke. Reid explains that the (...) Ideal Theory "leans with its whole weight upon a hypothesis...[t]hat nothing is perceived but what is in the mind which perceives it". Reid attributes to the Ideal Theory thesis. (shrink)

This book is a major contribution to the history of philosophy in the later medieval period (1250-1350). It focuses on cognitive theory, a subject of intense investigation during these years. In fact many of the issues that dominate philosophy of mind and epistemology today - intentionality, mental representation, scepticism, realism - were hotly debated in the later medieval period. The book offers a careful analysis of these debates, primarily through the work of Thomas Aquinas, John Olivi, and William Ockham. (...) Each of these figures attempts to reconceptualise cognition along direct realist lines, criticising in the process the standard Aristotelian account. Though of primary interest to medieval philosophers, the book presupposes no background knowledge of the medieval period, and will therefore interest a broader community of philosophers concerned with the origins of contemporary cognitive theory.

Reid maintained that the perceptions that we obtain from the senses of smell, taste, hearing, and touch are ‘suggested’ by corresponding sensations. However, he made an exception for the sense of vision. According to Reid, our perceptions of the real figure, position, and magnitude of bodies are suggested by their visible appearances, which are not sensations but objects of perception in their own right. These visible appearances have figure, position, and magnitude, as well as ‘colour,’ and the standard view among (...) Reid scholars has been that Reid maintained that our perceptions of visible figure, position, and magnitude are also not suggested by any sensation. They are instead suggested by the material impression on the retina. Gideon Yaffe challenges the standard interpretation. According to Yaffe, Reid believed that our perceptions of visible figure are suggested by corresponding sensations, by sensations of colour. We defend the standard interpretation of Reid. According to Reid, there is no “local sign” in our sensations of colour. The same colour sensation can be associated with different positions on the visual field, and different colour sensations can be associated to the same position on the visual field. According to Reid, we only have evidence for a correlation between the image on the retina and the perception of visible figure. (shrink)

Aristotle's illustrations of the fallacy of Figure of Speech (or Form of Expression) are none too convincing. They are tied to Aristotle's theory of categories and to peculiarities of Greek grammar that fail to hold appeal for a contemporary readership. Yet, upon closer inspection, Figure of Speech shows many points of contact with views and problems that inhabit 20th-century analytical philosophy. In the paper, some Aristotelian examples will be analyzed to gain a better understanding of this fallacy. The case (...) of the Third Man argument and some modern cases lend plausibility to the claim that Figure of Speech is of more interest as a type of fallacy than has generally been assumed. Finally, a case is made for the view that Figure of Speech, though listed among the fallacies dependent upon language, is not properly classified as a fallacy of ambiguity. More likely, it should be looked upon as a type of non sequitur. This has important consequences for the profile of dialogue associated with this fallacy. (shrink)

"What is at stake in this book is nothing less than a dramatically new way of approaching literature, one which in its unostentatious, low key way scandalously smashes a whole range of liberal humanist icons." --Terry Eagleton Who is more important: the reader, or the writer? Originally published in French in 1966, Pierre Macherey's first and most famous work, A Theory of Literary Production dared to challenge perceived wisdom, and quickly established him as a pivotal figure in literary (...) class='Hi'>theory. In this provocative work, Macherey puts the focus as much on the reader as the writer, stating that the very act of reading is a form of production in its own right, generating interpretation and meanings which are beyond the control of the author. Part of the birth of a whole new branch of post-structuralist theory, Macherey's work also influenced a new generation of critics among them Jacques Derrida, his contemporary, and Terry Eagleton. His ideas have also led some observers to claim that he announced the death of the author fully two years before Roland Barthes' famous essay. The reissue of this work as a Routledge Classic brings some radical ideas to a new audience, and argues persuasively for a totally new way of reading. As such, it is an essential work for anyone interested in the development of literary theory. (shrink)

In this book two of the leading figures in argumentation theory present a view of argumentation as a means of resolving differences of opinion by testing the acceptability of the disputed positions. Their model of a 'critical discussion' serves as a theoretical tool for analysing, evaluating and producing argumentative discourse. They develop a method for the reconstruction of argumentative discourse that takes into account all aspects that are relevant to a critical assessment. They also propose a practical code of (...) behaviour for discussants who want to resolve their differences in a reasonable way. This is a major contribution to the study of argumentation and will be of particular value to professionals and graduate students in speech communication, informal logic, rhetoric, critical thinking, linguistics, and philosophy.

Figurative communication (the use of metaphor, metonymy, hyperbole and irony) provides economy of expression, clarity, persuasiveness, politeness, evaluation, and communication of emotions. However, it also increases the potential for misunderstanding in situations when people lack shared background knowledge. This book combines theoretical frameworks with empirical studies that measure the effectiveness of different approaches to the use of figurative language in advertisements, to show how to maximise the benefits of creative metaphor and metonymy in global advertising. It highlights how subtle differences (...) in colour, layout, and combinations of different kinds of figurative language affect the reception and appreciation of creative advertising, shedding new light on the nature of figurative communication itself. With a balance between theory, experiments and practical case studies, this book is accessible for academics in linguistics and communication studies, as well as advertising and marketing professionals.

This chapter compares rationalist theories of sense perception to previously held theories of perception (especially of vision) and examines rationalist accounts of sensory qualities and sensory representation, of the role of the sense-based passions in guiding behavior, of the epistemological benefits and dangers of sense perception, and of mind–body relations. Each section begins with Descartes, the first major rationalist of the seventeenth century. The other major rationalists, Malebranche, Spinoza, and Leibniz, and also lesser known figures such as Pierre Regis, Jacques (...) Rohault, and Antoine Le Grand, were well acquainted with Descartes' work. Indeed, the first three were each deeply influenced by Descartes in their early years before developing their own philosophical systems, and the latter three were all advocates of Descartes' philosophy (perhaps with slight revision). Each of the major rationalists, while sharing some positions in common, developed a distinctive metaphysics of perception and of the mind–body relation. Earlier sections chart these differences and a final section sums up common features and touches on the continuing significance of their views. (shrink)

Semiotic Theory of Learning asks what learning is and what brings it about, challenging the hegemony of psychological and sociological constructions of learning in order to develop a burgeoning literature in semiotics as an educational foundation. Drawing on theoretical research and its application in empirical studies, the book attempts to avoid the problematization of the distinction between theory and practice in semiotics. It covers topics such as signs, significance and semiosis; the ontology of learning; the limits of learning; (...) ecosemiotics; ecology and sexuality. -/- The book is written by five of the key figures in the semiotics field, each committed to the belief that living is a process of interaction through acts of signification with a signifying environment. While the authors are agreed on the value of semiotic frameworks, the book aims not to present an entirely coherent line in every respect, but rather to reflect ongoing scholarship and debates in the area. In light of this, the book offers a range of possible interpretations of major semiotic theorists, unsettling assumptions while offering a fresh, and still developing, series of perspectives on learning from academics grounded in semiotics. -/- Semiotic Theory of Learning is a timely and valuable text that will be of great interest to academics, researchers and postgraduates working in the fields of educational studies, semiotics, psychology, philosophy, applied linguistics and media studies.

What is the relation between science and ideology? Are they incompatible, complementary or the same thing? Should science avoid “contamination” from ideology? Is there an only way to do science? Does anyone of them lead to the same results and give us the same worldview? We will focus on the figure of Alexander Bogdanov, Russian physician and philosopher, in order to discuss these and other relevant topics. His theories gave birth to what may be called later “the theory of (...) two sciences”, which entitles this work. (shrink)

This article sketches a theory of objective probability focusing on nomic probability, which is supposed to be the kind of probability figuring in statistical laws of nature. The theory is based upon a strengthened probability calculus and some epistemological principles that formulate a precise version of the statistical syllogism. It is shown that from this rather minimal basis it is possible to derive theorems comprising (1) a theory of direct inference, and (2) a theory of induction. (...) The theory of induction is not of the familiar Bayesian variety, but consists of a precise version of the traditional Nicod Principle and its statistical analogues. (shrink)

Whistleblowing” has entered the scholarly and the public debate as a way of describing the exposure by the member of an organization of episodes of corruption, fraud, or general abuses of power within the organization. We offer a critical survey of the main normative theories of whistleblowing in the current debate in political philosophy, with the illustrative aid of one of the epitomic figures of a whistleblower of our time: Edward Snowden. After conceptually separating whistleblowing from other forms of wrongdoing (...) disclosures, we introduce and discuss two families of normative views of this practice: the “Extrema Ratio” and the “Deontic” views. We show how the two views can be usefully considered in tandem to offer an all-round assessment of the moral justification of whistleblowing either as an extraordinary individual conscientious act of indictment or as an ordinary dutiful organizational practice of answerability that enables the capacity of self-correction of an organization.

This thesis is an examination and critique of naturalistic representational theories of phenomenal character. Phenomenal character refers to the distinctive quality that perceptual and sensational experiences seem to have; it is identified with 'what it is like' to undergo experiences. The central claims of representationalism are that phenomenal character is identical with the content of experience and that all representational states, bearing appropriate relations to the cognitive system, are conscious experiences. These claims are taken to explain both how conscious experiential (...) states arise and their nature. After examining the desiderata for naturalistic explanations, I argue that theories which ascribe nonconceptual content to experiences are the most plausible versions of representationalism. Further, causal covariation and teleological theories yield distinctive and interesting representationalist positions, hence, they become the focus of this study. To assess representationalism, I investigate whether all differences in phenomenal character can be correlated with differences in content. I claim that a useful distinction can be drawn between implicit and explicit content, which allows one to best describe the phenomena of perfect and relative pitch. I then argue that ambiguous figures show that two experiences can have the same content but different phenomenal character. I explicate the Inverted Earth hypothesis and claim that to identify content and phenomenal character, representationalists either have to condone the possibility of philosophical zombies, or hold that people lack authoritative first-person knowledge of their current experiences. Both these positions are unpalatable. Finally, I argue that representationalists cannot ascribe contents to experiences of novel colours to account for their phenomenal character. I also question, in light of dissociation phenomena, whether there is one distinctive relationship that all experiences bear to the cognitive system. I conclude that phenomenal character cannot be identical with the type of content under investigation, and that naturalistic representationalist theories cannot fully explain conscious experience.

What is depiction? This is a venerable question that has received many different answers throughout the whole history of philosophy, especially in contemporary times. A Syncretistic Theory of Depiction elaborates a new account on this matter by providing a theory of depiction that tries to combine the merits of the previous theories while dropping their defects. It is argued that a picture is a representation in a pictorial or figurative mode, and its 'figurativity' is given by a special (...) perception, perceiving-in, whose nature is reconceived. Such a perception inter alia grasps some properties which the picture's vehicle has in common with what is perceived in it; by so doing, that perception provides the picture with a figurative content. In contrast, the picture's representational value, its subject or its pictorial content, is given by a conventionally or causally based selection out of that figurative content. (shrink)

John P. Lizza has long been a major figure in the scholarly literature on criteria for death. His searching and penetrating critiques of the dominant biological paradigm, and his defense of a theory of death of the person as a psychophysical entity, have both significantly advanced the literature. In this special issue, Lizza reinforces his critiques of a strictly biological approach. In my commentary, I take up Lizza’s challenge regarding a biological concept of death. He is certainly right to (...) point out that science is not value-free; however, this does not imply that there cannot be a characterization of biological death that can be shown to be superior to other concepts. After characterizing and justifying such a theory of biological death, I show that patients who meet the diagnostic criteria for brain death are unequivocally biologically alive. However, with respect to concepts of personhood and related ideas, I urge the acceptance of a pluralism of such concepts for matters of public policy. (shrink)

This book explores the idea of human nature and the many understandings of it put forward by such diverse figures as Aristotle, Rousseau, Marx, Freud, Darwin, and E.O. Wilson.

Some chapters deal with the ideas of only one thinker, while others (such as the chapters on liberalism and feminism) present a variety of different positions. A clear (...) distinction is made between theories of human nature and the political theories which so often follow from them. For the new edition, Loptson has addressed the new developments in the rapidly expanding genetic and paleontological record, as well as expanded the discussion of the Christian theory of human nature by incorporating the ideas of the Marx scholar and social theorist G.A. Cohen. The new edition has also been substantively revised and updated throughout. (shrink)

The causal theory of action is widely recognized in the literature of the philosophy of action as the "standard story" of human action and agency -- the nearest approximation in the field to a theoretical orthodoxy. This volume brings together leading figures working in action theory today to discuss issues relating to the CTA and its applications, which range from experimental philosophy to moral psychology. Some of the contributors defend the theory while others criticize it; some draw (...) from historical sources while others focus on recent developments; some rely on the tools of analytic philosophy while others cite the latest empirical research on human action. All agree, however, on the centrality of the CTA in the philosophy of action. The contributors first consider metaphysical issues, then reasons-explanations of action, and, finally, new directions for thinking about the CTA. They discuss such topics as the tenability of some alternatives to the CTA; basic causal deviance; the etiology of action ; teleologism and anticausalism; and the compatibility of the CTA with theories of embodied cognition. Two contributors engage in an exchange of views on intentional omissions that stretches over four essays, directly responding to each other in their follow-up essays. As the action -oriented perspective becomes more influential in philosophy of mind and philosophy of cognitive science, this volume offers a long-needed debate over foundational issues.

The most accessible expression of François Laruelles non-philosophical, or non-standard, thought, _General Theory of Victims_ forges a new role for contemporary philosophers and intellectuals by rethinking their relation to victims. A key text in recent continental philosophy, it is indispensable for anyone interested in the debates surrounding materialism, philosophy of religion, and ethics. Transforming Joseph de Maistres adage that the executioner is the cornerstone of society, _General Theory of Victims_ instead proposes the victim as the cornerstone of humanity (...) and the key figure for contemporary thought. Laruelle condemns philosophy for participating in and legitimating the great persecutions of the twentieth century, and lays out a new vision of victim-oriented ethics. To do this, he engages the resources of both quantum physics and theology in order to adapt a key concept of non-philosophy, Man-in-person, for a new understanding of the victim. As Man-in-person, the victim is no longer exclusively defined by suffering, but has the capacity to rise up against the worlds persecution. Based on this, Laruelle develops a new ethical role for the intellectual in which he does not merely represent the victim, but imitates or clones it, thereby assisting the victims uprising within thought.

Grelet's solitary sailor is a radical theoretical figure, herald angel of an existential rebellion against the world and against philosophy's world-thought. Over a decade ago, Gilles Grelet left the city to live permanently on the sea, in silence and solitude, with no plans to return to land, rarely leaving his boat Théorème. An act of radical refusal, a process of undoing one by one the ties that attach humans to the world, for Grelet this departure was also inseparable from an (...) ongoing campaign of anti-philosophy. Like François Laruelle's "ordinary man" or Rousseau's "solitary walker," Grelet's solitary sailor is a radical theoretical figure, herald angel of an existential rebellion against the world and against philosophy's world-thought, point zero of an anti-philosophy as rigorous gnosis, and apprentice in the herethics of navigation. More than a set of scattered reflections, less than a system of thought, Theory of the Solitary Sailor is a gnostic device. It answers the supposed necessity of realizing the world-thought that is philosophy (or whatever takes its place) with a steadfast and melancholeric refusal. As indifferently serene and implacably violent as the ocean itself, devastating for the sufficiency of the world and the reign of semblance, this is a lived anti-philosophy, a perpetual assault waged from the waters off the coast of Brittany, amid sea and wind.

This essay develops a joint theory of rational (all-or-nothing) belief and degrees of belief. The theory is based on three assumptions: the logical closure of rational belief; the axioms of probability for rational degrees of belief; and the so-called Lockean thesis, in which the concepts of rational belief and rational degree of belief figure simultaneously. In spite of what is commonly believed, this essay will show that this combination of principles is satisfiable (and indeed nontrivially so) and that (...) the principles are jointly satisfied if and only if rational belief is equivalent to the assignment of a stably high rational degree of belief. Although the logical closure of belief and the Lockean thesis are attractive postulates in themselves, initially this may seem like a formal “curiosity”; however, as will be argued in the rest of the essay, a very reasonable theory of rational belief can be built around these principles that is not ad hoc and that has various philosophical features that are plausible independently. In particular, this essay shows that the theory allows for a solution to the Lottery Paradox, and it has nice applications to formal epistemology. The price that is to be paid for this theory is a strong dependency of belief on the context, where a context involves both the agent's degree of belief function and the partitioning or individuation of the underlying possibilities. But as this essay argues, that price seems to be affordable. (shrink)

The topic of truth has long been thought to be connected to scientific realism and its opposition. In this essay, I discuss the various ways that truth might be related to realism. First, I consider how truth might be of use when defining scientific realism and its opposition. Second, I consider whether various stances regarding realism require specific stances on the nature of truth. I survey "neutralist" views that argue that one's stance on realism is independent of one's view on (...) truth, and partisan positions that claim that one's attitude on realism is, in part, determined by one's theory of truth. Though partisan views have been popular, and defended by seminal figures such as Thomas Kuhn, Richard Rorty, Hilary Putnam, and Arthur Fine, I raise a number of objections for them. (shrink)

This essay seeks to illuminate the changing nature of experimental physics in the 1860s and 1870s by analysing the creation of dust tubes and dust figures by the German experimentalist August Kundt, and by showing how Kundt and his associate Emil Warburg used the ‘Kundt tube’ to test the new kinetic theory of gases. In so doing, the essay seeks to show how Kundt came to revise the vision of experimental physics that he had learned from his teacher Heinrich (...) Gustav Magnus, a vision in which the experimentalist's goal was to establish ‘the facts’. Kundt, by contrast, came to envision experimental physics as being in the service of theory: to confirm or disconfirm theory, or to provide theorists with new phenomena to theorize about. Kundt's vision, it is argued, is emblematic of the changing nature of experimental physics and reflective of the rise of the new subdisciplines of theoretical and experimental physics. (shrink)

The aim of this study was to examine the predictions of three theories of human logical reasoning, (a) mental model theory, (b) formal rules theory (e.g., PSYCOP), and (c) the probability heuristics model, regarding the inferences people make for extended categorical syllogisms. Most research with extended syllogisms has been restricted to the quantifier “All” and to an asymmetrical presentation. This study used three-premise syllogisms with the additional quantifiers that are used for traditional categorical syllogisms as well as additional (...) syllogistic figures. The predictions of the theories were examined using overall accuracy as well as a multinomial tree modelling technique. The results demonstrated that all three theories were able to predict response selections at high levels. However, the modelling analyses showed that the probability heuristics model did the best in both Experiments 1 and 2. (shrink)

Although the theory of the assertoric syllogism was Aristotle's great invention, one which dominated logical theory for the succeeding two millenia, accounts of the syllogism evolved and changed over that time. Indeed, in the twentieth century, doctrines were attributed to Aristotle which lost sight of what Aristotle intended. One of these mistaken doctrines was the very form of the syllogism: that a syllogism consists of three propositions containing three terms arranged in four figures. Yet another was that a (...) syllogism is a conditional proposition deduced from a set of axioms. There is even unclarity about what the basis of syllogistic validity consists in. Returning to Aristotle's text, and reading it in the light of commentary from late antiquity and the middle ages, we find a coherent and precise theory which shows all these claims to be based on a misunderstanding and misreading.
