In this paper, we introduce the variety of |$I$|-modal ririgs. We characterize the congruence lattice of its members by means of |$I$|-filters, and we provide a description of |$I$|-filter generation. We also provide an axiomatic presentation for the variety generated by chains of the subvariety of contractive |$I$|-modal ririgs. Finally, we introduce a Hilbert-style calculus for a logic with |$I$|-modal ririgs as an equivalent algebraic semantics and we prove that such a logic has the parametrized local deduction-detachment theorem.

In this paper we introduce the class of weak Heyting–Brouwer algebras (WHB-algebras, for short). We extend the well known duality between distributive lattices and Priestley spaces, in order to exhibit a relational Priestley-like duality for WHB-algebras. Finally, as an application of the duality, we build the tense extension of a WHB-algebra and we employ it as a tool for proving structural properties of the variety such as the finite model property, the amalgamation property, the congruence extension property and the Maehara (...) interpolation property.

Let |$\textbf{A}$| be a |$BCK$|-algebra and |$f:A^{k}\rightarrow A$| a function. The main goal of this article is to give a necessary and sufficient condition for |$f$| to be compatible with respect to every relative congruence of |$\textbf{A}$|⁠. We extend this result in some related algebras, as e.g. in pocrims.

Este artículo presenta el concepto de derecho desde diferentes ópticas, cada una de ellas con sus particularidades y la influencia que tienen en la actualidad en los ordenamientos jurídicos. El derecho no es un concepto fácil de entender, pero la forma en que se debe aplicar hoy día debe cobijar no solo la aplicación de la norma o enunciados normativos, sino componentes de índole moral, como los principios, todos ellos en pie de igualdad. No se trata de establecer una jerarquía (...) en los elementos jurídicos y morales, sino un criterio en el cual la corrección del ordenamiento jurídico lleve a la Justicia. Este texto parte de un método hermenéutico dialéctico, y tiene como finalidad ir construyendo un concepto de derecho que cumpla con los estándares de la corrección y la razonabilidad, como principios básicos para cumplir con la igualdad y la justicia.

Inspired by the definition of tense operators on distributive lattices presented by Chajda and Paseka in 2015, in this paper, we introduce and study the variety of tense distributive lattices with implication and we prove that these are categorically equivalent to a full subcategory of the category of tense centered Kleene algebras with implication. Moreover, we apply such an equivalence to describe the congruences of the algebras of each variety by means of tense 1-filters and tense centered deductive systems, respectively.

The aim of this study was to analyze the association between physical activity and eating habits during the COVID-19 pandemic among Brazilian adults. A sample of 1,929 participants answered an online survey, however 1,874 were included in the analysis. The impact of the COVID-19 pandemic on eating habits was assessed inquiring about participants' intake of fruits, vegetables, fried foods, and sweets during the pandemic. Physical activity was assessed by asking participants about their weekly frequency, intensity and number of minutes/hours engaging (...) in structured physical activities per week. Participants were then stratified into categories based on moderate-to-vigorous intensity and into active or inactive. Increased sweets consumption was the most commonly reported change to eating habits, followed by an increase in the consumption of vegetables, fruits, and fried foods. Physical activity practice was related to lower consumption of fried foods and sweets. A cluster analysis revealed subjects with higher the level of physical activity was more likely to follow a healthy diet. Thus, physical activity was positively associated with healthier eating habits. Health authorities must recommend regular physical as a strategy to improve overall health during the COVID-19 pandemic. Future studies should address the physical activity interventions to improve health status during a pandemic. (shrink)

BackgroundThe outbreak of novel coronavirus disease 2019 has caused a global panic and public concern due to its mortality ratio and lack of treatments/vaccines. Reduced levels of physical activity have been reported during the outbreak, affecting the normal daily pattern.ObjectiveTo investigate the relationship of physical activity level with sleep quality and the effects of reduction physical activity levels on sleep quality.MethodsA Google form was used to address personal information, COVID-19 personal care, physical activity, and mental health of 1,907 adult volunteers. (...) Binary logistic regression was used to verify the association of physical activity parameters and sleep quality.ResultsInsufficient physical activity levels were a risk factor to have disturbed sleep pattern [OR: 1.28, 95% CI ]; however, when the BMI was added to the analysis, there was no more statistical difference [OR: 1.23, 95% CI ]. On the other hand, we found that the reduction of physical activity levels was associated with negative changes in sleep quality [OR: 1.73, 95% CI ], regardless all the confounders [OR: 1.30, 95% CI ], unless when feeling of depression was added in Model 6 [OR: 1.28, 95% CI ].ConclusionDisruption in daily physical activity routine, rather than physical activity level, negatively influences sleep quality during the COVID-19 quarantine.

In this paper, we will study Heyting algebras endowed with tense negative operators, which we call tense H-algebras and we proof that these algebras are the algebraic semantics of the Intuitionistic Propositional Logic with Galois Negations. Finally, we will develop a Priestley-style duality for tense H-algebras.

RESUMEN El artículo responde algunas críticas planteadas por Ignacio Ávila a mi interpretación de la epistemología davidsoniana. Presento argumentos en contra de: a) que sea necesario distinguir entre representaciones epistemológicamente “peligrosas”e “inofensivas”; b) que el empirismo mínimo sea un tipo de realismo directo; c) que mi uso de la expresión “evidencia distal” y el interés por la teoría de la correspondencia sean asuntos ajenos a Davidson. Finalmente, sostengo que la triangulación es un elemento fundamental de la epistemología davidsoniana, pues permite (...) sortear la ansiedad realista manteniéndose en una postura no representacionalista. ABSTRACT In this article, I respond to some of Ignacio Ávila's criticisms of my interpretation of Davidson’s epistemology. I argue against: a) the need to distinguish between epistemologically “dangerous” and “harmless” representations; b) the idea that minimal empiricism is a kind of direct realism; and c) the claim that my usage of the expression “distal evidence” and interest in the theory of correspondence are issues that do not pertain to Davidson. Finally, I claim that triangulation is a key element in Davidsonian epistemology since it allows us to deal with the realist anxiety while maintaining a non-representationalist viewpoint. (shrink)

Este trabajo cuestiona el supuesto carácter intuitivo o natural del escepticismo acerca del mundo externo. En §1 examinamos una versión del argumento escéptico que se sostiene a partir de dos principios: clausura del conocimiento e indiferencia. Para profundizar la postura que ha defendido Michael Williams, en §2 ofrecemos un examen novedoso de la argumentación escéptica cartesiana que nos permite establecer que en dos argumentos de esta estrategia argumentativa resulta claro que la presunta naturalidad que el escéptico reclama es falsa y (...) que, antes bien, para lograr su conclusión, necesita asumir compromisos con el realismo epistémico, es decir, con la tesis de que nuestras creencias se ubican al interior de una jerarquía epistemológica de acuerdo únicamente con su contenido y en abstracto. Finalmente, basados en argumentos de inspiración wittgensteiniana, en §3 mostramos cómo es que, en contra del realismo epistémico, cada creencia desempeña un papel justificativo según el contexto pertinente.

The purpose of the paper is to cast doubt on the alleged intuitive or natural character of the skeptical argument about the external world. In §1, we examine a version of the skeptical argument based on the epistemic closure principle and the indifference principle. In §2, in order to deepen the view defended by Michael Williams, we offer a novel examination of the Cartesian skeptical argumentation to show that it is clear that the alleged naturalness claimed by the skeptic is (...) nowhere to be found in two arguments which can be found in such argumentative strategy; moreover, to reach her conclusion, the skeptic needs to commit to epistemological realism, namely, the claim that each of our beliefs belongs to an epistemological hierarchy based solely on its content. In §3, based on arguments inspired by Wittgenstein, contra epistemological realism, we show how each belief has a justificatory role based on its context. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Machiavellian Rhetoric: From the Counter-Reformation to MiltonWilliam WalkerMachiavellian Rhetoric: From the Counter-Reformation to Milton, by Victoria Kahn; xv & 3l4 pp. Princeton: Princeton University Press, 1994, $29.95.The premise of this book is that the account of Machiavelli’s politics given by Quentin Skinner and J. G. A. Pocock is fundamentally inadequate. It is inadequate in that it fails to recognize that the Machiavelli of force and fraud—what Kahn calls (...) the “rhetorical Machiavel”—is inseparable from the republican, and that his politics “could be used not only pro and contra republicanism but pro and contra secular thought” (p. 12). This failure is answerable to a flawed methodology: reading Machiavelli’s texts for content, Skinner and Pocock neglect Machiavelli’s rhetorical techniques which “fragment, subvert, or otherwise qualify the literal sense” of his texts (p. 5). By paying attention to these rhetorical techniques, Kahn claims to correct Skinner and Pocock’s misunderstanding of Machiavelli as a virtuous, secular republican and “to provide a revised history of Renaissance Machiavellism, particularly in England” (p. 4).The main reason for the failure of this project is Kahn’s crude understanding of Skinner and Pocock. Rather than seeing Machiavelli assimilating virtù with classical virtue, Skinner observes that Machiavelli’s exclusion of justice from republican virtù is an epoch-making break with the classical republican analysis of the cardinal virtues as expounded in Cicero’s Of Duties. Pocock, too, clearly recognizes that Roman republican virtù as it is documented by Machiavelli includes what Kahn calls “the resources of the Machiavel” (p. 124). In addition, rather than equating Machiavellism with secular republicanism, Pocock observes that it was difficult for not just Machiavelli but everyone in the Renaissance to conceive the moment of recreating the republic without making recourse to the apocalyptic moment, the moment at which grace acted in history. And to think as Kahn does that Pocock needs to be told that Machiavellism could be “used for sectarian religious purposes” (p. 8) is simply to disregard Pocock’s own assertion of this fact and his tremendous meditation on how this actually occurred in the millennially oriented society of seventeenth-century England.The claims which Kahn makes on the basis of her perceptive close readings [End Page 370] of the rhetoric of Machiavelli’s The Prince and The Discourses, then, do not significantly revise Pocock and Skinner. Neither do her considerations of readings of Machiavelli by counter-Reformation thinkers such as Zuccolo, Caterino, and Botero, sixteenth-century Englishmen such as Starkey, Gardiner, Ralegh, Bacon, and Shakespeare, and the seventeenth-century Englishmen who were involved in civil war and Interregnum political debates. These considerations simply make the point that Machiavelli was read in very different ways and was used to support very different political agendas—an interesting point, and one which is entirely consistent with the views of Skinner and Pocock. Kahn’s revised history of English Machiavellism is further compromised by her construal, beginning in chapter five, of Machiavellism as “the Machiavellian topics of legitimacy and force, virtue and success, intention and effect, means and ends” (p. 156). Kahn seems to suppose that because Machiavelli writes about these topics, these topics are Machiavellian, and anyone who writes about them in English is therefore a subscriber to “English Machiavellism.” This move allows her to consider all kinds of texts which only seem remotely connected to Machiavelli—from sixteenth-century debates over things indifferent, to Coriolanus, to masques by Jonson and Carew, to Milton’s Areopagitica, Comus, and Paradise Lost—as cases of “English Machiavellism.” Kahn ends up defining Machiavellism so widely, that is, that she finds it everywhere. On the other hand, she ignores it where it is most conspicuous: she gives passing attention to Marchamont Nedham’s fully articulated republicanism and no attention whatsoever to the most comprehensive English reading of Machiavelli in the seventeenth century: James Harrington’s Oceana.A revised history of Renaissance Machiavellism, particularly in England?

William Jaworski shows how hylomorphism can be used to solve mind-body problems--the question of how thought, feeling, perception, and other mental phenomena fit into the physical world. Hylomorphism claims that structure is a basic ontological and explanatory principle, and is responsible for individuals being the kinds of things they are, and having the powers or capacities they have. From a hylomorphic perspective, mind-body problems are byproducts of a worldview that rejects structure, and which lacks a basic principle which distinguishes (...) the parts of the physical universe that can think, feel, and perceive from those that can't. Without such a principle, the existence of those powers in the physical world can start to look inexplicable and mysterious. But if mental phenomena are structural phenomena then they are uncontroversially part of the physical world. Hylomorphism thus provides an elegant way of solving mind-body problems. (shrink)

For this 1897 publication, the American philosopher William James brought together ten essays, some of which were originally talks given to Ivy League societies. Accessible to a broader audience, these non-technical essays illustrate the author's pragmatic approach to belief and morality, arguing for faith and action in spite of uncertainty. James thought his audiences suffered 'paralysis of their native capacity for faith' while awaiting scientific grounds for belief. His response consisted in an attitude of 'radical empiricism', which deals practically (...) rather than ideologically with real-world phenomena. When facing a 'momentous' decision about belief, he says, we both can and must choose the best hypothesis. The first four essays apply this principle to religious faith, and the rest explore the pragmatic approach to such topics as determinism, ethics and individual achievement. James developed his ideas further in The Varieties of Religious Experience and Pragmatism, both of which are reissued in this series. (shrink)

Philosophers of mind have long been interested in the relation between two ideas: that causality plays an essential role in our understanding of the mental; and that we can gain an understanding of belief and desire by considering the ascription of attitudes to people on the basis of what they say and do. Many have thought that those ideas are incompatible. William Child argues that there is in fact no tension between them, and that we should accept both. He (...) shows how we can have a causal understanding of the mental without having to see attitudes and experiences as internal, causally interacting entities and he defends this view against influential objections. The book offers detailed discussions of many of Donald Davidson's contributions to the philosophy of mind, and also considers the work of Dennett, Anscombe, McDowell, and Rorty, among others. Issues discussed include: the nature of intentional phenomena; causal explanation; the character of visual experience; psychological explanation; and the causal relevance of mental properties.

Several of William James' finest essays are brought together in this collection, including his spiritual masterwork The Will to Believe, and his famous lecture concerning immortality. The Will to Believe was first delivered as a lengthy lecture by William James in 1896. Following a strong reception, it was later published as a distinct book in its own right. Setting out to defend the right of individuals to be religious irrespective of pure logic and reason, the lecture highlights many (...) of the proven advantages conferred by the belief in a guiding divine force. The benefits of belief to the believer are thus noted. James deftly cites many real life examples to prove his points - noting that many tasks or duties require confidence, he notes how individuals can perform and surmount difficulties if they believe in the divine. For such persons to abandon faith would therefore be irrational, as their religious beliefs have helped them in life. This argument is closely aligned with James' personal philosophical alignment with pragmatism. The Will to Believe also contains arguments in favor of persons having their own free will. James contested simply that as he believed in his own free will, he had it. As well as this, we hear several philosophical arguments in which James discusses the merits of empiricism versus absolutism. Other essays in this compendium include 'Is Life Worth Living?' and 'The Dilemma of Determinism'. In these and other writings, James demonstrates a superb command of philosophical principles and theoretical daring, at various times explaining and refuting established discussions on the subjects. The final essay in this edition, Human Immortality, sees James object to the notion that humans cannot be immortal if their bodies and minds are separated due to death. He objects to the assertion that human thought is concluded if the brain ceases to function, noting that human consciousness exists with the world and may philosophically have a life of its own. Notable for both his psychological and philosophical ideas, William James would author numerous lectures and books surrounding both subjects. The importance of spiritualism to the human being, the permanence of the spirit, and its effects on the thought processes, is but one area in which James distinguished himself. (shrink)

One of the most influential men of his time, philosopher, psychologist, educator, and author William James (1842-1910) helped lead the transition from a predominantly European-centered nineteenth-century philosophy to a new "pragmatic" American philosophy. Helping to pave the way was his seminal book Pragmatism (1907), in which he included a chapter on "Truth," an essay which provoked severe criticism. In response, he wrote the present work, an attempt to bring together all he had ever written on the theory of knowledge, (...) including an article on the function of cognition, later polemic and expository contributions, and some replies to previous criticism. The result was a full and definitive expression of the pragmatist "epistemology" from James' point of view. In the book, he urges the reader to "turn away from abstractions, verbal solutions, fixed principles, and pretended absolutes and look for concreteness and facts, action and power," arguing that "the ultimate test for us of what a truth means is the conduct it dictates or inspires." For students, scholars--anyone interested in William James or the history of American philosophical thought--this book offers an in-depth exposition of the influential ideas of one of the greatest American thinkers.

The degradation of modern sport--its commercialization, trivialization, widespread cheating, cult of athletic stars and celebrities, and manipulation by the media--has led to calls for its transformation. William J. Morgan constructs a critical theory of sport that shores up the weak arguments of past attempts and points a way forward to making sport more humane, compelling, and substantive. Drawing on the work of social theorists, Morgan challenges scholars and fans alike to explore new spaces in sport culture and imagine the (...) rich cultural and political possibilities to be found in the pastimes we follow with such passion.

Over the past two decades, the renowned political theorist William E. Connolly has developed a powerful theory of pluralism as the basis of a territorial politics. In this concise volume, Connolly launches a new defense of pluralism, contending that it has a renewed relevance in light of pressing global and national concerns, including the war in Iraq, the movement for a Palestinian state, and the fight for gay and lesbian rights. Connolly contends that deep, multidimensional pluralism is the best (...) way to promote justice and inclusion without violence. He advocates a deep pluralism—in contrast to shallow, secular pluralism—that helps to create space for different groups to bring their religious faiths into the public realm. This form of deep pluralism extends far beyond faith, encompassing multiple dimensions of social and personal lives, including household organization and sexuality. Connolly looks at pluralism not only in light of faith but also in relation to evil, ethics, relativism, globalization, and sovereignty. In the process, he engages many writers and theorists—among them, Spinoza, William James, Henri Bergson, Marcel Proust, Gilles Deleuze, Giorgio Agamben, Talal Asad, Michael Hardt, and Antonio Negri. _Pluralism_ is the first book in which Connolly explains the relationship between pluralism and the experience of time, and he offers readings of several films that address how time is understood, including _Time Code_, _Far from Heaven_, _Waking Life_, and _The Maltese Falcon_. In this necessary book Connolly brings a compelling, accessible philosophical critique together with his personal commitment to an inclusive political agenda to suggest how we might—and why we must—cultivate pluralism within both society and ourselves.

William S. Robinson has for many years written insightfully about the mind-body problem. In Understanding Phenomenal Consciousness he focuses on sensory experience and perception qualities such as colours, sounds and odours to present a dualistic view of the mind, called Qualitative Event Realism, that goes against the dominant materialist views. This theory is relevant to the development of a science of consciousness which is now being pursued not only by philosophers but by researchers in psychology and the brain sciences. (...)

This article articulates and defends F. H. Bradley's regress argument against external relations using contemporary analytic techniques and conceptuality. Bradley's argument is usually quickly dismissed as if it were beneath serious consideration. But I shall maintain that Bradley's argument, suitably reconstructed, is a powerful argument, plausibly premised, and free of such obvious fallacies as petitio principii. Thus it does not rest on the question‐begging assumption that all relations are internal, as Russell, and more recently van Inwagen, maintain. Bradley does not (...) attack external relations in order to affirm a doctrine of internal relations, and his monism is not derived from the internality of all relations, but from the self‐contradictory nature of all relations. For Bradley, it is the “relational situation”as such that is ontologically defective. (shrink)

Now in its Third Edition, Philosophy of Language: A Contemporary Introduction introduces students to the main issues and theories in twentieth-century philosophy of language, focusing specifically on linguistic phenomena. Author William G. Lycan structures the book into four general parts. Part I, Reference and Referring, includes topics such as Russell's theory of descriptions (and its objections), Donnellan's distinction, problems of anaphora, the description theory of proper names, Searle's cluster theory, and the causal-historical theory. Part II, Theories of Meaning, surveys (...) the competing theories of linguistic meaning and compares their various advantages and liabilities. Part III, Pragmatics and Speech Acts, introduces the basic concepts of linguistic pragmatics and includes a detailed discussion of the problem of indirect force. Part IV, The Expressive and the Figurative, examines various forms of expressive language and what "metaphorical meaning" is and how most listeners readily grasp it. (shrink)

An Oxford philosopher argues that solving today's problems might require putting future generations ahead of ourselves The human story is just beginning. There are five thousand years of written history, but perhaps millions more to come. In What We Owe the Future, philosopher William MacAskill develops a perspective he calls longtermism to argue that this fact is of enormous moral importance. While we are comfortable thinking about the equal moral worth of humans alive today, we haven't considered the moral (...) weight of future generations. We have put them at grave risk, and not just with climate change. AI could lock humans into perpetual dystopia, or pandemics could end us. But the future could be wonderful: moral and technological progress could result in unimaginable human flourishing. The future is in our hands. As MacAskill shows, we can make the world better for billions of years to come. Perhaps even more importantly, he shows us just how much is at stake if we consign future generations to oblivion.

In About Time, William Friedman provides a new integrated look at research on the psychological processes that underlie the human experience of time.

Contemporary science presents us with the remarkable theory that the universe began to exist about fifteen billion years ago with a cataclysmic explosion called "the Big Bang." The question of whether Big Bang cosmology supports theism or atheism has long been a matter of discussion among the general public and in popular science books, but has received scant attention from philosophers. This book sets out to fill this gap by means of a sustained debate between two philosophers, William Lane (...) Craig and Quentin Smith, who defend opposing positions. Craig argues that the Big Bang that began the universe was created by God, while Smith argues that the Big Bang has no cause. Alternating chapters by the two philosophers criticize and attempt to refute preceding arguments. Their arguments are based on Einstein's theory of relativity and include a discussion of the new quantum cosmology recently developed by Stephen Hawking and popularized in A Brief History of Time.

How is a legitimate state possible? Obedience, coercion and intrusion are three ideas that seem inseparable from all government and seem to render state authority presumptively illegitimate. This book exposes three fallacies inspired by these ideas and in doing so challenges assumptions shared by liberals, libertarians, cultural conservatives, moderates and Marxists.

The dark matter problem in astrophysics exposes an underappreciated weakness in the evidential warrant for General Relativity (GR). The "dark matter double bind" entails that GR gets no differential evidential support from dynamical phenomena occurring at scales larger than our solar system, as compared to members of a significant class of rival gravitation theories. These rivals are each empirically indistinguishable from GR for phenomena taking place at solar system scales, but make predictions that may differ radically from GR's at larger (...) scales. Thus the typical confidence in the universal applicability of GR is insufficiently warranted in the present evidential context. (shrink)

This book explores how globalisation influences the understanding of law. Adopting a broad concept of law and a global perspective, it critically reviews mainstream Western traditions of academic law and legal theory. Its central thesis is that most processes of so-called 'globalisation' take place at sub-global levels and that a healthy cosmopolitan discipline of law should encompass all levels of social relations and the legal ordering of these relations. It illustrates how the mainstream Western canon of jurisprudence needs to be (...) critically reviewed and extended to take account of other legal traditions and cultures. Written by the one of the foremost scholars in the field, this important work presents an exciting alternative vision of jurisprudence. It challenges the traditional canon of legal theorists and guides the reader through a field undergoing seismic changes in the era of globalisation. This is essential reading for all students of jurisprudence and legal theory. (shrink)

Peter Kosso discusses the weak gravitational lensing observations of the Bullet Cluster and argues that dark matter can be detected in this system solely through the equivalence principle without the need to specify a full theory of gravity. This paper argues that Kosso gets some of the details wrong in his analysis of the implications of the Bullet Cluster observations for the Dark Matter Double Bind and the possibility of constructing robust tests of theories of gravity at galactic and greater (...) scales. Even the Bullet Cluster evidence is not sufficiently detailed to allow precision tests of General Relativity that would distinguish it from its rivals at galactic and greater scales. Taking into account the total evidence available, we cannot rule out “ugly” solutions to the dynamical discrepancy in astrophysics that involve both a large quantity of dark matter and a theory of gravity whose predictions differ significantly from those of General Relativity for interactions taking place at galactic and greater scales.

Does the cosmological argument (CA) depend on the ontological (OA)? That depends. If the OA is an argument “from mere concepts,” then no; if the OA is an argument from possibility, then yes.

Can beliefs to the effect that god is manifesting himself in a certain way to the believer ("m-beliefs") be justified by its seeming to the believer that he experiences god doing that? the issue is discussed in the context of several concepts of justification. on a "normative" concept of justification the answer will depend on what one's intellectual obligations are vis-a-vis practices of belief formation. on a rigorous view of such obligations one is justified in forming a m-belief on the (...) basis of experience only if one has adequate reasons for taking that practice to be reliable. on a more permissive view of such obligations, one is justified only if one lacks adequate reasons for taking the practice to be unreliable. it is suggested that neither this practice nor, e.g., the practice of forming perceptual beliefs on the basis of sense perception passes the stronger test, but that they both pass the weaker test.

What is intentionality? Intentionality is a distinguishing characteristic of states of mind : that they are about things outside themselves. About this book: William Lyons explores various ways in which philosophers have tried to explain intentionality, and then suggests a new way. Part I of the book gives a critical account of the five most comprehensive and prominent current approaches to intentionality. These approaches can be summarised as the instrumentalist approach, derived from Carnap and Quine and culminating in the (...) work of Daniel Dennett; the linguistic approach, derived from the work of Chomsky and exhibited most fully in the work of Jerry Fodor; the biological approach, developed by Ruth Garrett Millikan, Colin McGinn, and others; the information-processing approach which has been given a definitive form in the work of Fred Dretske; and the functional role approach of Brian Loar. In Part II, Professor Lyons sets out a multi-level, developmental approach to intentionality. Drawing upon work in neurophysiology and psychology, the author argues that intentionality is to be found, in different forms, at the levels of brain functioning, prelinguistic consciousness, language, and at the holistic level of `whole person performance' which is demarcated by our ordinary everyday talk about beliefs, desires, hopes, intentions, and the other `propositional attitudes'. Written in a direct, clear, and lively style, the extended survey of contemporary debate in Part I will be invaluable to the student of philosophy of mind or cognitive science as well as to the scholars and graduate students who will find an original new theory to contend with in Part II.

Hume says we never have grounds to believe in miracles. He’s right, but many commentators misunderstand his theory of probability and therefore his argument. This book shows that Humean probability descends from Roman law, and once properly contextualized historically and philosophically, Hume’s argument survives the criticisms leveled against it.

In lieu of an abstract, here is a brief excerpt of the content:What Do You Mean, Rhetoric Is Epistemic?William D. HarpineIn 1967, Robert L. Scott (1967) advocated that "rhetoric is epistemic." This concept has enriched the work of rhetorical theorists and critics. Scott's essay is founded in a concept of argumentative justification in rhetoric, viewed as an alternative to analytic logic. Other writers, including Brummett (1976), Railsback (1983), and Cherwitz and Hikins (1986), have offered variations on Scott's theme. The (...) thesis that rhetoric is epistemic has been controversial, however, and from the tone of the debate one may draw two conclusions: many rhetorical theorists feel that Scott was on to something important, and the thesis as it has been developed is flawed. Much of the dispute centers on what the thesis means. These discussions have not yet adequately clarified that issue.The philosopher's most fundamental obligation is to define terms with care. It is in precisely this respect that the rhetoric-is-epistemic theorists have fallen short. Some of the key terms in this literature include rhetoric, knowledge, certainty, and truth. In too many cases, the writers on rhetorical epistemology have not defined their key terms at all. In other cases, their definitions are inadequate or inconsistent. This essay undertakes to sort out the most important definitional problems, which center on the rhetoric-is-epistemic theorists' habit of equivocating about the meanings of "rhetoric" and "certainty." The result makes it possible to endorse the validity of Scott's essentially ethical conclusions, while dismissing a number of unnecessary complexities in the arguments made by rhetoric-as-epistemic theorists. Finally, a few alternatives that might lead to more robust foundations for the rhetoric-as-epistemic thesis are suggested.In 1978, after reviewing four distinct interpretations of the claim that rhetoric is epistemic, Leff concluded that clarification of what that claim means "deserves more disciplined treatment than it has received in the recent literature" (1978, 77). The same could still be said. After some [End Page 335] thirty years of active research and speculation on the topic, one now sees fewer publications specifically advocating that rhetoric is epistemic. The distinguished rhetorical theorist Barry Brummett (1990) has declared the thesis deceased (69-72).All the same, textbook authors treat the thesis as a given, despite their tendency to interpret it in wildly different ways. Foss, for example, puts forward a view that "in the field of communication, the idea that rhetoric creates reality is known as the notion that rhetoric is epistemic, which simply means that rhetoric creates knowledge; epistemology is the study of the origin and nature of knowledge" (1989, 122; emphasis in the original). This version of the thesis, claiming that rhetoric actually "creates reality," might be more ontological than it is epistemic.1 Herrick takes a dialectical view that "through rhetorical interaction, people come to accept some ideas as true and to reject others as false. Thus, rhetoric's epistemic function in society can be seen in some ways to be a result of its benefit of testing ideas." Herrick continues that "once an idea has been tested thoroughly by a group, community, and society, it becomes part of what these groups take to be knowledge." Herrick contrasts this with the rejected view that "knowledge is all objective in nature and comes to us by way of direct experience or education" (1997, 22). Both Herrick and Foss offer interesting theses, and both attribute their views to Scott, but their views are obviously very different. There can be no surer evidence of the failure to use terms precisely.Brummett (1990) attributes the demise of rhetoric-is-epistemic research to the failure of critics to employ the idea in rhetorical criticism. Brummett might be right to the extent that much of the rhetoric-is-epistemic literature is indeed exceptionally abstract. Specific discussions might clarify some issues. Nonetheless, some notable rhetorical critics have indeed employed a concept that rhetoric is epistemic (e.g., Scott and Klumpp 1984; Sullivan 1992). The issues remain unclear. Furthermore, rhetorical criticism per se cannot clarify the meanings of theoretical terms.
