The word "modem" in the title of this book refers primarily to post-medieval discussions, but it also hints at those medieval mo dal theories which were considered modem in contradistinction to ancient conceptions and which in different ways influenced philosophical discussions during the early modem period. The me dieval developments are investigated in the opening paper, 'The Foundations of Modality and Conceivability in Descartes and His Predecessors', by Lilli Alanen and Simo Knuuttila. Boethius's works from the early sixth century (...) belonged to the sources from which early medieval thinkers obtained their knowledge of ancient thought. They offered extensive discus sions of traditional modal conceptions the basic forms of which were: (1) the paradigm of possibility as a potency striving to realize itself; (2) the "statistical" interpretation of modal no tions where necessity means actuality in all relevant cases or omnitemporal actuality, possibility means actuality in some rel evant cases or sometimes, and impossibility means omnitemporal non-actuality; and (3) the "logical" definition of possibility as something which, being assumed, results in nothing contradic tory. Boethius accepted the Aristotelian view according to which total possibilities in the first sense must prove their met tle through actualization and possibilities in the third sense are assumed to be realized in our actual history. On these presump tions, all of the above-mentioned ancient paradigms imply the Principle of Plenitude according to which no genuine possibility remains unrealized. (shrink)

Modality: A History provides readers a sweeping study of the history of philosophical work on modal concepts. Everyday discourse is saturated with appeals to what might be the case or to what must be true or to what cannot happen. Possibility, necessity, and impossibility are modal terms, and philosophers have long wondered how to best understand them. This volume traces the history of some of the most prominent and important contributions to our understanding of possibility and (...) necessity over the past two and half millennia of western philosophy, from ancient Greek philosophers through current debates in the 21st century. Over the course of nine chapters from prominent scholars, this volume traces a history of modal theorizing that begins with extended discussions of Aristotle and the Stoics. Several chapters discuss insights and disagreements among Latin, Arabic, and Jewish medieval scholastics, such as Al-Ghazâlî, Scotus, and Crescas. Three chapters center on early modern philosophers, whose modal views were deeply shaped by this conceptual inheritance but also departed from it in significant ways: Descartes, Malebranche, Locke, Spinoza, Leibniz, and Hume. Kant and Hegel's modal contributions are presented in their own chapter, and another chapter traces the legacy of Kant's account on early-to-mid 20th century modal views, including Husserl, Heidegger, Russell, and Quine. The revival of modal metaphysics in the more recent work of Kripke, Marcus, and Lewis has led to a new flourishing of modal theories, including in recent debates among neo-Aristotelians, as the final chapter illustrates. Although modal concepts are interesting and important on their own, theories of modality often intersect with other significant philosophical topics, such as time, freedom, and God. Modal concepts also extend beyond metaphysics. To illustrate the role of modality in other domains, several small-scale studies, or Reflections, are dispersed among these main chapters on modality in cosmology, religion, music, literature, and logic. Readers will learn how a seemingly timeless and changeless cluster of modal concepts have undergone significant revisions and enjoy a rich developmental history. (shrink)

Interest in the metaphysics and logic of possible worlds goes back at least as far as Aristotle, but few books address the history of these important concepts. This volume offers new essays on the theories about the logical modalities held by leading philosophers from Aristotle in ancient Greece to Rudolf Carnap in the twentieth century. The story begins with an illuminating discussion of Aristotle's views on the connection between logic and metaphysics, continues through the Stoic and mediaeval traditions, and (...) then moves to the early modern period with particular attention to Locke and Leibniz. The views of Kant, Peirce, C. I. Lewis and Carnap complete the volume. Many of the essays illuminate the connection between the historical figures studied, and recent or current work in the philosophy of modality. The result is a rich and wide-ranging picture of the history of the logical modalities. (shrink)

The Actual and the Possible presents new essays by leading specialists on modality and the metaphysics of modality in the history of modern philosophy from the seventeenth to the twentieth centuries. It revisits key moments in the history of modern modal doctrines, and illuminates lesser-knownmoments of that history. The ultimate purpose of this historical approach is to contextualise and even to offer some alternatives to dominant positions within the contemporary philosophy of modality. Hence the (...) volume contains not only new scholarship on the early-modern doctrines of Baruch Spinoza,G. W. F. Leibniz, Christian Wolff and Immanuel Kant, but also work relating to less familiar nineteenth-century thinkers such as Alexius Meinong and Jan Lukasiewicz, together with essays on celebrated nineteenth- and twentieth-century thinkers such as G. W. F. Hegel, Martin Heidegger and BertrandRussell, whose modal doctrines have not previously garnered the attention they deserve. The volume thus covers a variety of traditions, and its historical range extends to the end of the twentieth century, addressing the legacy of W. V. Quine's critique of modality within recent analyticphilosophy. (shrink)

Greek, Indian and Arabic Logic marks the initial appearance of the multi-volume Handbook of the History of Logic. Additional volumes will be published when ready, rather than in strict chronological order. Soon to appear are The Rise of Modern Logic: From Leibniz to Frege. Also in preparation are Logic From Russell to Gödel, The Emergence of Classical Logic, Logic and the Modalities in the Twentieth Century, and The Many-Valued and Non-Monotonic Turn in Logic. Further volumes will follow, including Mediaeval (...) and Renaissance Logic and Logic: A History of its Central. In designing the Handbook of the History of Logic, the Editors have taken the view that the history of logic holds more than an antiquarian interest, and that a knowledge of logic's rich and sophisticated development is, in various respects, relevant to the research programmes of the present day. Ancient logic is no exception. The present volume attests to the distant origins of some of modern logic's most important features, such as can be found in the claim by the authors of the chapter on Aristotle's early logic that, from its infancy, the theory of the syllogism is an example of an intuitionistic, non-monotonic, relevantly paraconsistent logic. Similarly, in addition to its comparative earliness, what is striking about the best of the Megarian and Stoic traditions is their sophistication and originality. Logic is an indispensably important pivot of the Western intellectual tradition. But, as the chapters on Indian and Arabic logic make clear, logic's parentage extends more widely than any direct line from the Greek city states. It is hardly surprising, therefore, that for centuries logic has been an unfetteredly international enterprise, whose research programmes reach to every corner of the learned world. Like its companion volumes, Greek, Indian and Arabic Logic is the result of a design that gives to its distinguished authors as much space as would be needed to produce highly authoritative chapters, rich in detail and interpretative reach. The aim of the Editors is to have placed before the relevant intellectual communities a research tool of indispensable value. Together with the other volumes, Greek, Indian and Arabic Logic, will be essential reading for everyone with a curiosity about logic's long development, especially researchers, graduate and senior undergraduate students in logic in all its forms, argumentation theory, AI and computer science, cognitive psychology and neuroscience, linguistics, forensics, philosophy and the history of philosophy, and the history of ideas.

Modality - the question of what is possible and what is necessary - is a fundamental area of philosophy and philosophical research. The Routledge Handbook of Modality is an outstanding reference source to the key topics, problems and debates in this exciting subject and is the first collection of its kind. Comprising thirty-five chapters by a team of international contributors the Handbook is divided into seven clear parts: worlds and modality essentialism, ontological dependence, and modality modal (...) anti-realism epistemology of modality modality in science modality in logic and mathematics modality in the history of philosophy. Within these sections the central issues, debates and problems are examined, including possible worlds, essentialism, counterfactuals, ontological dependence, modal fictionalism, deflationism, the integration challenge, conceivability, a priori knowledge, laws of nature, natural kinds, and logical necessity. The Routledge Handbook of Modality is essential reading for students and researchers in epistemology, metaphysics and philosophy of language. It will also be very useful for those in related fields in philosophy such as philosophy of mathematics, logic and philosophy of science. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Avicenna's Theory of Science: Logic, Metaphysics, Epistemology by Riccardo StrobinoThérèse-Anne DruartRiccardo Strobino. Avicenna's Theory of Science: Logic, Metaphysics, Epistemology. Oakland: University of California Press, 2021. Pp. xvi + 428. Hardback, $95.00.Strobino's remarkable book does not simply present Avicenna's theory of science; it also highlights the importance of demonstration not only for logic but also for metaphysics and epistemology. Hence, Strobino's work is essential to appreciate (...) and better understand Avicenna's philosophy as a whole.Strobino grounds his research on Avicenna's theory of science in his Book of Demonstration in the Shifā', which focuses on Aristotle's Posterior Analytics. Taking into account the lack of any translation into English or any other main modern language as well as the lack of a full medieval Latin translation (only chapter 7 of book 3 exists in a medieval Latin version) of Avicenna's text, Strobino kindly provides in appendix C (357–71) a detailed "map" of this text, useful not only to readers who cannot handle Arabic but even to those who can, as the [End Page 326] text is so rich and complex. A simple but careful look at this map confirms what Strobino makes clear and insists upon: Avicenna greatly develops, enriches, completes, and even outgrows some of Aristotle's views. The Book of Demonstration is far more than a commentary on the Posterior Analytics; it is a complete reworking of it.Strobino shows that Avicenna grounds his theory of demonstration and science on two basic notions—conception (tasawwur) and assertion (tasdīq, which some other scholars translate as "assent")—and so gives a unified approach to his theory. Scientific conceptions require better understanding of definition and description. Avicenna builds definitions and descriptions on essentialism and, therefore, grounds them in metaphysics. As for scientific assertions, in contradistinction to nonscientific ones, they must be necessary and give the cause. Therefore, Avicenna places great importance on modality and develops modal syllogisms, whereas Aristotle focused on categorical syllogisms and neglected hypothetical and disjunctive syllogisms. Avicenna also elaborates a sophisticated account of modality and its metaphysical implications. Furthermore, he broadens and enriches the appreciation of causality and explanation. These developments, according to Strobino, lead Avicenna to set forth an intricate division and hierarchy of the sciences under metaphysics, which provides their ultimate principles and allows for a unified understanding of the sciences while respecting their particularities.According to Strobino, Avicenna is keen to develop a theory of science that gives a good account of science as it is practiced. Strobino carefully shows how Avicenna's theory better reflects this practice than does Aristotle's.Strobino does not simply highlight how much Avicenna distances himself from Aristotle and goes far beyond what the Posterior Analytics yields, but also shows how much Avicenna relies on points adumbrated by his predecessor al-Fārābī in his own Book of Demonstration.The way Strobino through his analysis of demonstration links Avicenna's understanding of logic, epistemology, and metaphysics underscores the coherence and unity of Avicenna's philosophy. Scholars were aware of the importance of demonstration for Avicenna in various philosophical fields, but until the release of this book, they seemed not to have fully grasped the centrality and essential role played by the Avicennian understanding and focus on demonstration.Of course, Strobino does not limit himself to an analysis of passages in the Book of Demonstration. He has an encompassing knowledge of Avicenna's texts and uses them well to flesh out and enrich what remains terse in the Book of Demonstration. He even takes into account the way one of his successors, al-Tūsī, reads him. He also shows an extensive and wide-ranging knowledge of Aristotle's texts and of Aristotelian scholarship, as well as an interest in the Greek commentators and Galen and their relevance for interpreting Avicenna.Avicenna's Theory of Science is not an easy book to read, as it is often very technical, particularly when dealing with purely logical points or issues, but reading it is rewarding if one does so slowly and meditatively. The author, in fact, illuminates difficult matters but does not waste words. From... (shrink)

What is possible and why? What is the difference between the merely possible and the actual? In Kants Modal Metaphysics Nicholas Stang examines Kants lifelong engagement with these questions and their role in his philosophical development. This is the first book to trace Kants theory of possibility all theway from the so-called pre-Critical writings of the 1750s and 1760s to the Critical system of philosophy inaugurated by the Critique of Pure Reason in 1781. Stang argues that the key to (...) understanding both the change and the continuity between Kants pre-Critical and Critical theory of possibility is his transformation of the ontological question about possibility-what is it for a being to be possible?-into a question in transcendental philosophy-what is it to represent an object as possible?

Examining afresh the 16th-century style of mannerism, Sjoerd van Tuinen synthesises philosophy and aesthetics to demonstrate not only the contemporary relevance of mannerism but its broader significance as a form of modal thinking. Beyond a style of art that spurned the balance and proportion of earlier Renaissance painting in favour of compositional instability and tension, this book looks a-historically at mannerism to investigate what it can tell us about continental modal metaphysics, focusing in particular on its artificial and what Van (...) Tuinen calls 'secondary' nature. In three main parts, Van Tuinen first explores the ontology, aesthetics and ethics of mannerism. He then develops this through an extended study of Leibniz as a modal and indeed mannerist philosopher, before outlining in the final part a (neo)-mannerist aesthetics that incorporates diagrammatics, alchemy and contemporary technologies of speculative design. Drawing on Bergson, Simondon, Deleuze, Stengers and Agamben, together with artworks from Lomazzo to Arcimboldo, The Philosophy of Mannerism uncovers the rich new pathways created by the combination of philosophy, art history and contemporary theory.

Forensic authorship analysis is based on two assumptions: that every individual has a unique idiolect, and that features characteristic of that idiolect will recur with a relatively stable frequency. Yet, a speaker’s language can change with age, affective states, according to audience, or genre. Thus, studies on authorship analysis should adopt the theory that while some linguistic parameters of an idiolect can remain stable, others can change depending on various circumstances. This investigation, which takes a constructional and functional-based approach (...) to discourse-level phenomena in idiolectal stability, analyzes cross-genre data produced by nine Mexican participants throughout a twelve-year time span. This study contributes to a greater understanding of the linguistic elements that survive genre effects and are potentially useful in both investigative and evidential forensic linguistic work. We provide a detailed description of linguistic features, their specific values, and context-dependent interpretation, keeping in mind the context of expert linguistic testimony, with its preference for methods which “employ linguistically motivated analyses in combination with quantitative tools” (Solan & Tiersma, 2004, p.463). Our findings show that idiolectal style tends to remain stable across genres and communication modes in epistemic modality constructions. Epistemic markers —specifically, markers indicating low commitment by the speaker (e.g., _no sé_ ‘I don’t know’) or expressing indirectness when introducing the illocutionary force (e.g., _la verdad [es que]_ ‘the truth [is that]’)— display idiolectal stability, as these markers seem to be the most effective in terms of allowing speakers to strategically manifest the extent of their knowledge regarding what is said.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 29, Number 1, April 2003, pp. 43-61 Conceivability and Modality in Hume: A Lemma in an Argument in Defense of Skeptical Realism PETER KAIL Introduction: A Realist View of Necessity and the Key Objection Those who seek to defend a skeptical realist reading of Hume on causal necessity have a number of textual and philosophical hurdles to clear. This paper attempts to clear one and (...) only one hurdle. So one should not look here for a complete case in favor of a skeptical realist reading: I merely attempt to dispose of what looks like a decisive objection to a conception of objective necessary connection which, I believe, Hume endorses. The skeptical realist Hume, as I and others read him, is a Hume who wishes to deny that human beings have the cognitive wherewithal to perceive or grasp the necessary connection which relates the objects of genuine causal relations. His "skeptical conclusion" is that we cannot grasp in re necessity, nor that there is no necessity. That bald statement, of course, leaves us with a whole host of questions: why should we think that Hume believes that there really is causal necessity? Is this position compatible with his positive account of our idea of necessary connection, or his theory of belief (and of ideas in general)? What of Hume's talk of "necessity in the objects" lacking a meaning? And how does Peter Kail is Lecturer in the Department of Philosophy, The University of Edinburgh, David Hume Tower, George Square, Edinburgh ΕΗ8 9JX, United Kingdom, e-mail: [email protected] 44 Peter Kail such a skeptical realist reading mesh with Hume's general philosophical project (or, indeed, what does it tell us about that)? None of these questions can be addressed here.1 Instead, as I said, I want to defend a conception of necessary connection that seems vulnerable to a decisive objection. First, then, I need to spell out what that conception is. Hume takes acquaintance with necessary connection (the "power, force or efficacy") to entail certain conceptual-cum-epistemological consequences. Roughly, acquaintance with necessary connection would entail (a) the possibility of a priori knowledge of the relevant cause's effect and (b) the impossibility of conceiving the cause without its effect. He tells us that: From the first appearance of an object, we can never conjecture what effect will result from it. But were the power or energy of any cause discoverable by the mind, we could foresee the effect, even without experience; and might, at first, pronounce with certainty concerning it, by the mere dint of thought and reasoning. (EHU 7.1.7; SBN 63) A similar claim is made in the Treatise: We must distinctly and particularly conceive the connection betwixt cause and effect, and be able to pronounce, from a simple view of the one, that it must be follow'd or preceded by the other. This is the true manner of conceiving a particular power in a particular body. (T 1.3.14.13; SBN 161) These aspects of Hume's treatment of necessity constitute what Galen Strawson has called the "AP Property."2 Notice that the AP Property furnishes a thin, but nevertheless contentful, specification of that of which we are ignorant when Hume says we are ignorant of necessary connection. Necessary connection is that feature, acquaintance with which, would yield what is specified in the AP Property. One can go further by suggesting that what the AP Property picks out are unknown (and, for reasons of deep contingency, unknowable) essences.3 This thought is intimated by a number of things Hume says: 'Tis easy to observe, that in tracing this relation, the inference we draw from cause to effect, is not deriv'd merely from a survey of these particular objects, and from such a penetration into their essences as may discover the dependence of the one upon the other. (T 1.3.6.1; SBN 86 (my emphasis)) Hume Studies Conceivability and Modality 45 And: It has been observ'd already, that in no single instance the ultimate connexion of any objects is discoverable, either by our senses or reason, and that we can never penetrate...

We want to consider anew the question, which is recurrent along the history of philosophy, of the relationship between rationality and mathematics, by inquiring to which extent the structuration of rationality, which ensures the unity of its function under a variety of forms (and even according to an evolution of these forms), could be considered as homeomorphic with that of mathematical thought, taken in its movement and made concrete in its theories. This idea, which is as old as philosophy (...) itself, although it has not been dominant, has still been present to some degree in the thought of modern science, in Descartes as well as in Kant, Poincaré or Einstein (and a few other scientists and philosophers). It has been often harshly questioned, notably in the contemporaneous period, due to the failure of the logistic programme, as well as to the variety of “empirical” knowledges, and, in a general way, to the character of knowledges that show them as transitory, evolutive and mind-built. However, the analysis of scientific thought through its inventive and creative processes leads to characterize this thought as a type of rational form whose configurations can be detailed rather precisely. In this work we shall propose, first, a quick sketch of some philosophical requirements for such a research programme, among which the need for an harmonization, and even a conciliation, between the notions of rational (or rationality), of intuitive grasp and of creative thought. Then we shall examine some processes of creative scientific thought bearing on the knowledge and the understanding of the world, distinct from mathematics although keeping tight relations with them. Contemporary physical theories are privileged witnesses in this respect, for in them the rational thought of phenomena makes an intrinsic use of mathematical thought, which contributes to the structuration of the formers and to the expression of their concepts (which entails the physical contents of the latter). The General Theory of Relativity and the Quantum Theory are exemplar to this, as they directly reveal what can be called the “drag of physical thought par the mathematical form”, which makes possible to overcome the limitations of the physical knowledge previously adquired. This process is tightly related to the modalities and to the stucture of the rational thought underlying it. This is what we would like to show. DOI:10.5007/1808-1711.2011v15n2p303. (shrink)

The aim of this thematically unified anthology is to track the history of epistemic logic, to consider some important applications of these logics of knowledge and belief in a variety of fields, and finally to discuss future directions of research with particular emphasis on 'active agenthood' and multi-modal systems. It is accessible to researchers and graduate students in philosophy, computer science, game theory, economics and related disciplines utilizing the means and methods of epistemic logic.

This monograph explores the logical systems of early logicians in the Arabic tradition from a theoretical perspective, providing a complete panorama of early Arabic logic and centering it within an expansive historical context. By thoroughly examining the writings of the first Arabic logicians, al-Fārābī, Avicenna and Averroes, the author analyzes their respective theories, discusses their relationship to the syllogistics of Aristotle and his followers, and measures their influence on later logical systems. Beginning with an introduction to the writings of the (...) most prominent Arabic logicians, the author scrutinizes these works to determine their categorical logic, as well as their modal and hypothetical logics. Where most other studies written on this subject focus on the Arabic logicians’ epistemology, metaphysics, and theology, this volume takes a unique approach by focusing on the actual technical aspects and features of their logics. The author then moves on to examine the original texts as closely as possible and employs the symbolism of modern propositional, predicate, and modal logics, rendering the arguments of each logician clearly and precisely while clarifying the theories themselves in order to determine the differences between the Arabic logicians’ systems and those of Aristotle. By providing a detailed examination of theories that are still not very well-known in Western countries, the author is able to assess the improvements that can be found in the Arabic writings, and to situate Arabic logic within the breadth of the history of logic. This unique study will appeal mainly to historians of logic, logicians, and philosophers who seek a better understanding of the Arabic tradition. It also will be of interest to modern logicians who wish to delve into the historical aspects and progression of their discipline. Furthermore, this book will serve as a valuable resource for graduate students who wish to complement their general knowledge of Arabic culture, logic, and sciences. (shrink)

In ”Formal Problems about Knowledge,” Roy Sorensen examines epistemological issues that have logical aspects. He uses Fitch's proof for unknowables and the surprise test paradox to illustrate the hopes of the modal logicians who developed epistemic logic, and he considers the epistemology of proof with the help of the knower paradox. One solution to this paradox is that knowledge is not closed under deduction. Sorensen reviews the broader history of this maneuver along with the relevant alternatives model (...) of knowledge which assumes that ”know” is an absolute term like ”flat.” Sorensen argues that the difference between epistemic absolute terms and extensional absolute terms gives rise to an asymmetry that undermines recent claims that there is a structural parallel between the supervaluational and epistemicist theories of vagueness, and he suggests that we have overestimated the ability of logical demonstration to produce knowledge.

In a career extending over almost six decades, Nicholas Rescher has conducted researches in almost every principal area of philosophy, historical and systematic alike. In this extraordinary volume, two dozen scholars join in offering penetrating discussions of various facets of Rescher s investigations. The result is an instructively critical panorama of the many-faceted contributions of this important American philosopher. Born in Germany in 1928, Nicholas Rescher came to the U.S. at the age of nine. He is University Professor of Philosophy (...) at the University of Pittsburgh where he has also served as Chairman of the Philosophy Department and as director (and currently chairman) of the Center for Philosophy of Science. In a productive research career extending over six decades, he has established himself as a systematic philosopher of the old style. His work represents a many-sided approach to fundamental philosophical issues that weaves together threads of thought from continental idealism and American pragmatism. And apart from this larger program Rescher has made various specific contributions to logic (the conception autodescriptive systems of many-sided logic), the history of logic (the medieval Arabic theory of modal syllogistic), to the theory of knowledge (epistemetrics as a quantitative approach in theoretical epistemology), and to the philosophy of science (the theory of a logarithmic retardation of scientific progress). Rescher has also worked in the area of futuristics, and along with Olaf Helmer and Norman Dalkey is co-inaugurator of the so-called Delphi method of forecasting. Ten books about Rescher s philosophy have been published in four languages. Rescher earned his doctorate at Princeton in 1951 while still at the age of twenty-two a record for Princeton s Department of Philosophy. He has served as a President of the American Philosophical Association, of the American Catholic Philosophy Association, of the American G. W. Leibniz Society, of the C. S. Peirce Society, and of the American Metaphysical Society. He was the founder of the American Philosophical Quarterly. An honorary member of Corpus Christi College, Oxford, he has been elected to membership in the European Academy of Arts and Sciences (Academia Europaea), the Royal Society of Canada, the Institut International de Philosophie, and several other learned academies. Having held visiting lectureships at Oxford, Constance, Salamanca, Munich, and Marburg, he has been awarded fellowships by the Ford, Guggenheim, and National Science Foundations. Author of some hundred books ranging over many areas of philosophy, over a dozen of them translated from English into other languages, he is the recipient of eight honorary degrees from universities on three continents. He was awarded the Alexander von Humboldt Prize for Humanistic Scholarship in 1984, the Belgian Prix Mercier in 2005, and the Aquinas Medal of the American Catholic Philosophical Association in 2007.".

Some of the most eminent and enduring philosophical questions concern matters of priority: what is prior to what? What 'grounds' what? Is, for instance, matter prior to mind? Recently, a vivid debate has arisen about how such questions have to be understood. Can the relevant notion or notions of priority be spelled out? And how do they relate to other metaphysical notions, such as modality, truth-making or essence? This volume of new essays, by leading figures in contemporary metaphysics, is (...) the first to address and investigate the metaphysical idea that certain facts are grounded in other facts. An introduction introduces and surveys the debate, examining its history as well as its central systematic aspects. The volume will be of wide interest to students and scholars of metaphysics.

I offer you some theories of intellectual obligations and rights (virtue Ethics): initially, RBT (a Right to Believe Truth, if something is true it follows one has a right to believe it), and, NDSM (one has no right to believe a contradiction, i.e., No right to commit Doxastic Self-Mutilation). Evidence for both below. Anthropology, Psychology, computer software, Sociology, and the neurosciences prove things about human beliefs, and History, Economics, and comparative law can provide evidence of value about theories of (...) rights. However, insofar as we have methods within Philosophy to help us formulate precise concepts of 'belief' and 'rights', methods that also help us to prove links (or absence thereof) amongst families of concepts of rights and belief, our discipline is in and of itself capable of sound reasoning about issues as puzzling as the following. Suppose a Jane who does not believe in God yet who believes she ought to so believe: Jane is undergoing doxastic moral regret (moral regret for lack of faith). We have all known such Janes and perhaps at one time or another even been one. Paradox: given RBT and NDSM, Jane as described not only does not exist, Jane cannot exist. Thus, to enrich the ways in which Philosophy need not get all its evidence from other academic disciplines, I present a brief introduction to what I call Neutral Universal Frames (NUFs). NUFs solve hard puzzles about interactions among modal concepts of belief and rights, concepts that occur in RBT, NDSM and the description of our Janes. NUFs for theories precisely articulated via any two or more modal concepts are a powerful and immensely general set of tools enabling us to define rich theories of truth ("models on frames") to test philosophical theories for internal consistency and to prove the existence of connections (or absence thereof) amongst alternative articulations of philosophical theories. NUFs thereby add to the constructive knowledge producing way Logics intersect with Philosophy of Religion. And we will soon see why Jane, be she named 'Jane' or known simply as you: cannot exist.

Clare, the titular character of The Time Traveller's Wife, reflects that "Everything seems simple until you think about it." This might well be a mantra for the whole of philosophy, but a fair few terms tend to stick out. "Knowledge", "goodness" and "happiness" for example, are all pervasive everyday terms that undergo significant philosophical analysis. "Luck", I think, is another one of these terms. Wishing someone good luck in their projects, and cursing our bad luck when success seems so (...) close to our reach or failure could have so easily been otherwise, happens so often that we rarely stop to reflect on what we really mean. Philosophical reflection on the nature of luck has a rich tradition, that is by no stretch confined to the Western philosophical canon. However, it has only very recently become one of the goals of philosophy to provide a clear account of what luck actually amounts to. This, in part, is the goal of this thesis. The thesis has two primary motivations. The first is to offer and defend a general account of luck that overcomes the problems faced by the current accounts of luck that are available in the current philosophical literature. The second is to apply this general account of luck to the areas of metaethics and epistemology where luck has been a pervasive and problematic concept, and demonstrate how this account of luck may resolve or further illuminate some of the problems that the notion has generated. The thesis is roughly split into two parts. The first half of the thesis focuses on the former objective of offering an account of luck. Chapter 1 offers a selected history of the philosophy of luck that spans from the Ancient Greeks to the present day, so that we might properly situate the current work on luck as part of the broader historical importance of the concept. Chapter 2 will set out the major rival to the theory of luck that I will offer - the lack of control account of luck. LCAL has various iterations across the literature, but is most clearly articulated by Wayne Riggs and E.J. Coffman. Both Coffman and Riggs add and adapt their own conditions to LCAL specifically so that the account may overcome several problems that have been levied against it. These further conditions are not incompatible so, to provide the strongest lack of control account possible, I have combined them to form a lack of control account I have called Combined LCAL - LCAL. The latter part of the chapter pits LCAL against some of the problems that have been raised against LCAL. However, despite the efforts of both Riggs and Coffman, even LCAL fails to counter some of these objections. For these reasons I have rejected LCAL has a viable candidate for an account of luck. Chapter 3 sets out a modal account of luck, as argued for by Pritchard, where an event is lucky only if it occurs in the actual world, but not in a relevant set of nearby possible worlds. Here I further elaborate on how we should understand the modal distances using Lewisian possible world semantics, and what worlds should be taken into consideration when fixing the relevant set of nearby possible worlds. I argue that these relevant sets of worlds should be fixed according to the domain of inquiry of which the luck is being applied - this I call the type of luck. Examples of this is the current literature are resultant luck - the type of luck concerned with the results of our actions, and veritic luck - the type of luck concerned with the modal safety of our belief formation. Due to the multitude of types of luck across disciplinary areas, a general modal account of luck requires flexibility in what factors should fix the relevant sets of possible worlds. I achieve this by providing a [TYPE] function for the general modal account of luck, which is used as a mean of inserting the relevant fixing conditions for any domain of inquiry. Chapter 3, in a similar vein to Chapter 2, pits the general modal account of luck against some of the problems that have been levied against MAL, specifically the Buried Treasure problem raised by Lackey and the agent causation problem as raised by Levy. More successfully, the modal account offered stands up against these criticisms. For these reasons, the modal condition understood with the [TYPE] function and Lewisian semantics concerning modal distances, will be adopted to make up one half of the conditions for my account of luck. Chapter 4 will look at the second condition for an account of luck - the significance condition. The chapter will set out the reasons for adopting a significance condition at all, and some of the ways in which the condition has been articulated by Rescher, Pritchard and Ballantyne. All of these current views of the significance condition will be found wanting due to their inability to make sense of certain kinds of luck in specific normative domains. For example, Ballantyne's account of significance focuses on the interests of an agent, yet for certain types of moral luck, the interests of the agent are irrelevant. Instead, I propose a relativised significance condition, where the value of the event is relative to the value of the normative domain in which the luck is being ascribed. Epistemic luck requires a focus on the epistemic significance of the event for the agent, moral luck requires a focus on the moral or ethical significance of the event for the agent, and so on. This I call the kind of luck. Similar to the [TYPE] function for the modal condition for luck, the significance condition requires a [NORMATIVE DOMAIN] function where the relevant normative domain can be inserted depending on the kind of luck. This version of the significance condition will be conjoined with the modal condition as set out in Chapter 3 to form the correct general account of luck. Chapter 5 is the first chapter of the second half of the thesis that concerns applying the account of luck set out in part 1 to more specific domains of inquiry. Chapter 5 concerns moral luck, more specifically, resultant moral luck. Moral luck has traditionally been understood in terms of lack of control. This chapter looks at how Pritchard and Driver have attempted to understand moral luck using modal conditions. However, it is argued that these attempts would be more successful if we adopted the account of luck that I have offered in previous chapters. The chapter will go on to look at two possible problems that may be faced by this modal account of luck, and how it may resolve these problems. Chapter 6, the final chapter, looks at epistemic luck, specifically how the adoption of the modal account I have offered resolves a particular problem targeted at anti-luck epistemology by Ballantyne. The problem, Ballantyne argues, is that given that luck requires a significance condition, the degree of significance affects the degree of luck and that the degree of luck involved in our belief formation affects whether we are in a position to know the target proposition, that the result is that degree of significance affects our ability to know. For at least some instances of this - such as the aesthetic significance that we assign to the target proposition - the result will be that non-epistemic factors that have no relevance at all whether an agent is in a position to know will affect that agent's position to know. The resolution to this problem can be found in a two part solution. The first part is to demonstrate that any degree of veritic epistemic luck results in the agent failing to know. The second is that through the relativisation of the significance condition, any type of value will not affect an agent's position to know, only the epistemic value. With these two considerations in mind, the latter of which that can only be held through the adoption of the modal account of luck I have offered, the problem may be resolved. (shrink)

somewhat like Henkin's nonstandard interpretation of higher-order logics, while the right semantics [or logical modalities is an analogue to the standard of type theory in Henkin's sense. interpretation Another possibility would be to follow W.V.

This (...) looks in fact like one of the most interesting possible theories I have dreamt of developing but undoubtedly never will. Its kinship with Kant's way of thinking should be obvious. Besides putting the entire enterprise of possible-worlds semantics into a perspective, we can also see that the actual history of possible-worlds seman­ tics is more complicated than it might first appear to be. For the standard in­ terpretation of modal logics has reared its beautiful head repeatedly in the writings of Stig Kanger, Richard Montague the pre-Montague-semantics theorist, and Nino Cocchiarella.

This is the first comprehensive study of Michael Oakeshott as a philosopher rather than a political theorist, which is how most commentators have regarded him. Indeed, the careful reading of his published and unpublished writings that Terry Nardin provides here shows that Oakeshott's concerns have been primarily philosophical, not political. These writings go far beyond politics to offer a critical philosophy of human activity and of the disciplines that interpret and explain it. Oakeshott argues that inquiry can be independent of (...) practical concerns, even when its subject is the thought and action of human beings. Although the book considers Oakeshott's views on morality, law, and government, it is primarily concerned with his ideas about the character of knowledge, especially knowledge of intelligent human conduct, and focuses attention on the concepts of modality, contingency, and civility that are central to Oakeshott's philosophy as a whole. Nardin seeks to show how Oakeshott's critique of scientism and other forms of foundationalism supports a powerful version of the argument that history is the proper mode for understanding human choice and action. The book thus provides the fullest discussion available of Oakeshott's antifoundationalist view of epistemology, metaphysics, and the philosophy of history and the human sciences. It examines his arguments concerning the criteria of truth, the forms of knowledge, the relationship between theory and practice, the place of interpretation in the social sciences, the nature and importance of historical explanation, and the definition of philosophy itself. And it is the first study to look at Oakeshott's relationship to phenomenology, hermeneutics, and other movements in twentieth-century Continental philosophy. (shrink)

Michael Oakeshott is widely recognised to be one of the most original political philosophers of the twentieth century. He also developed a very influential interpretation of the ideas of the great seventeenth century philosopher Thomas Hobbes. While many commentators have noted the importance of Hobbes for understanding Oakeshott’s thought itself, this is the first book to provide a systematic interpretation of Oakeshott’s philosophy by paying close attention to all facets of Oakeshott’s reading of Hobbes. On the surface, Oakeshott, the philosophical (...) idealist and critic of rationalism in politics, would seem to have little in common with Hobbes, who is often regarded as a classic materialist and rationalist philosopher. This work shows, however, that despite appearances, there are many basic affinities between the two thinkers and that Oakeshott brought to the surface aspects of Hobbes’s thought that had previously been overlooked by Hobbes scholars. The development of Oakeshott’s own theory is shown to mirror changes in his reading of Hobbes and many of the distinctive features of Oakeshott’s thought including the modal and sceptical conception of human knowledge, the ‘morality of individuality’, the theory of civil association, and the critique of rationalism all find a fascinating focal point in his writings on Hobbes. Some attention is also paid to Oakeshott’s religious ideas, indicating what they share with Hobbes’s philosophy of religion. The book situates Oakeshott’s reading in relation to some other important twentieth century interpretations of Hobbes and examines its significance for broader debates in political theory and the history of ideas.

Perception is the ultimate source of our knowledge about contingent facts. It is an extremely important philosophical development that starting in the last quarter of the twentieth century, philosophers have begun to change how they think of perception. The traditional view of perception focussed on sensory receptors; it has become clear, however, that perceptual systems radically transform the output of these receptors, yielding content concerning objects and events in the external world. Adequate understanding of this process requires that we (...) think of perception in new ways—how it operates, the differences among the modalities, and integration of content provided by the individual senses. Philosophers have developed new analytic tools, and opened themselves up to new ways of thinking about the relationship of perception to knowledge. The Oxford Handbook of the Philosophy of Perception is a collection of entries by leading researchers that reviews these new directions in philosophical thought. The Introduction to the Handbook reviews the history of the subject from its beginnings in ancient Greece to the nineteenth century, and the way that science and philosophy have together produced new conceptions during the last hundred years. It shows how the new thinking about perception has led to a complex web of theories. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:HUMAN NATURE AND POLITICS: A MIMETIC READING OF CRISIS AND CONFLICT IN THE WORK OF NICCOLÒ MACHIAVELLI 1 Harald Wydra Universität Regensberg Perhaps more than any other political philosopher2, Machiavelli's writings have given rise to extremely controversial and emotionally charged interpretations.3 Ifone were to pinpoint the guiding lines ofdispute in Machiavelli scholarship, one could argue that his "foes" are convinced of his amorality and the tyrannical bias, while his (...) "friends" stress the liberal and republican basis ofhis teaching. This debate between good and the evil in Machiavelli's teaching has accompanied the conflict on the tyrannical and the republican character of his work ever since.4 While the essence of his prescriptions continues to be contested, most interpreters concur on Machiavelli 's realism or political pragmatism defined in The Prince 25 as effectual 1 I am grateful to Anthony J. Parel, Arpad Szakolczai, and AdolfTrägler for comments on an earlier draft of this essay. 2Perhaps with the exception of Marx who shares with Machiavelli the heritage of an inflationary and contentious scholarship. Despite this resemblance, there are fundamental differences when it comes to declare oneself a follower of Machiavelli or follower of Marx. See Aron (256-259). 3In his extensive overview, Berlin estimates the totality of the bibliography at more than 3,000 titles. Needless to say that is has considerably increased since then. The recent wave of new translations into English (Mansfield and Tarcov, or Codevilla) and several new approaches provide for the richness of debate. This debate sometimes acquires a heated intensity, such as in the exchange on Strauss's Machiavelli between Mansfield and Pocock in Political Theory, 3:4 (1975), 372-405. 4See for a recent update the introduction to a new translation ofthe Discourses in Mansfield and Tarcov. Harald Wydra37 truth (verità ejfetuale). In this stress on factual reality as opposed to imagination many have seen the sources of Machiavelli's advocacy of technicity, rationality and reason of state. Such a viewpoint is supported by Machiavelli's pure and emotionless style ofwriting. Machiavelli's effectual truth is essentially about the mastery over conflict and contingency in politics. Yet, there are hardly systematic studies on the status and role ofpolitical conflict and its consequences for political order in Machiavelli's work.5 Most classical studies include analysis of conflict (Pocock; Lefort; Sasso), but they do so by sticking to the natural textual division ofhis major works. This article sets out to elaborate some guidelines ofa Machiavellian theory ofconflict by linking it to René Girard's theory of mimetic conflict. It aims to achieve two things: first, to analyze the nature of political conflict in Machiavelli's work. Second, to reexamine some widespread assumption on the autonomy of politics. The Affinity of Machiavelli and Girard: Crisis and Conflict Methodologically, a reading ofMachiavelli through Girard has a status different from that of orthodox comparisons oftwo thinkers.6 This can be illustrated by considering Raymond Aron's comparison between Machiavelli and Marx. On the one hand, Machiavelli's political philosophy is marked by a stress on cyclical repetition and permanent instability. His realism maintains that the more things change the more they remain the same. On the other hand, Marx's economic philosophy of history envisages long-term progress and as such reflects upon change by its confidence in Providence. Yet, essentially both works are concerned with the contingent modalities of collective conflict over time. While for Machiavelli the struggle for power unfolds between political groups such as nobles and the people, Marx suggests the social and economic roots ofconflicts in social formations. Against this background, a reading of Machiavelli through Girard diverges from conventional comparisons. Machiavelli's work emanates from his experience as a practitioner ofpolitics who aims to be the counsellor of Princes. A trained historian and literary critic, Girard analyzes fundamental 5To my knowledge, by far the most balanced and detailed treatment is given by Sasso.

The paper posits a relationship between the sensory modality of touch, including a sense of active movement, and early modern knowledge of active powers in nature. It seeks to appreciate the strength and appeal of knowledge built on the active-passive distinction, including that which was retrospectively labeled animist. Using statements by Descartes, Hobbes, Locke, Spinoza, Leibniz, and Stahl, rather than detailed new readings of texts, the paper asks whether scholars drew on phenomenal, or conscious, awareness of activity (...) as effort encountering resistance when they reasoned about activity in the world. How were there relations and analogies between descriptions of psyche’s relation to body, of the relation of living forces to matter, of relations among material objects, of God’s relationship to His creation, and of relations involving causal agency generally? It is possible to understand what were later called animistic theories as belonging to the mainstream of the new natural philosophy, not to a residue of unscientific argument. Early modern theories of active and vital powers cannot be dismissed because they were based, in error, on mere analogy to human action. Rather, they had a central position in reasoning grounded in phenomenal awareness of action-resistance when a person is “in touch.”. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Possibility and Necessity in the Time of Peter Abelard by Irene BininiWolfgang LenzenIrene Binini. Possibility and Necessity in the Time of Peter Abelard. Investigating Medieval Philosophy Series. Leiden: Brill, 2021. Pp. xii + 326. Hardback, $166.00.This book is an impressive work written by a young Italian scholar who received her PhD only five years ago in Pisa. It is divided into three parts. Part 1 gives a survey (...) of "Early 12th-Century Debates on Modal Propositions"; part 2 is devoted to "Abelard's Modal Logic"; [End Page 327] part 3 deals with the views of "Abelard on the Metaphysics and Epistemology of Modalities." The author displays a profound knowledge of the relevant literature. The primary sources comprise twenty manuscripts preserved in various European libraries, plus forty-eight printed works (from Abelard to William of Sherwood). The list of secondary sources contains altogether 136 items from A (Astroh) to Z (Zagzebski), but, interestingly, it does not mention a monograph that, by its very title, claims to give an exposition of Abelard's logic, namely Maria Teresa Beonio-Brocchieri Fumagalli's La Logica di Abelardo (Firenze: La Nuova Italia, 1964).As far as I can judge (as a nonnative English-speaker), the linguistic quality of Binini's book is quite good. The explanations in the main text, including the translations from Latin sources, are easily comprehensible, and the many quotations (distributed over no less than 655 footnotes) are almost without any fault. Thus, the book rightly deserves inclusion in the prestigious series Investigating Medieval Philosophy. Yet, at least according to my taste, the book contains many redundancies. Again and again, the author first explains a certain issue at some length, then confirms the correctness of her interpretation by means of a longer (English) quotation, and finally reconfirms it by fully quoting the Latin text in the footnotes.As Binini explains in the book's concluding chapter, her aim is to present "an all-encompassing reflection on [Abelard's] works on modalities" and "a comparison between these works and the parallel reflections advanced by other masters and logicians in the early 12th century" (308). She undoubtedly achieves this goal. The comparison of Abelard's views on possibility and necessity with the views of other logicians is mainly carried out in chapters 1–3. Ancient and early medieval logicians such as, in particular, the Stoics and Boethius favored the basic idea that "something," p, is necessary if and only if p is always the case (or true). Accordingly, p is possible if and only if p is at least sometime the case. Abelard, however, was not willing to accept that each possibility has to become realized at some time. He instead offered a "nature-based characterization of possibility" that can "account for unrealized, past, counterfactual, and even unactualizable possibilities" (308). Abelard's idea is that something, x, is possibly a P if and only if the property of being P is compatible with the nature of x. Hence this view basically amounts to a de re conception of possibility that attributes modalities to things, while the temporal view attributes modal properties primarily to propositions (or states of affairs) and hence can be labeled de dicto (or de sensu).Let us now turn to Binini's twofold aim (as formulated on the back cover of her book) to present a "uniform and consistent" reassessment of Abelard's theory of modalities and of his modal logic. The former task is tackled in chapters 8–10. After summarizing, in chapter 8, Abelard's general views on "Nature and Modalities," chapter 9 is devoted to a detailed discussion of the "Many Senses of Possibility." In five consecutive sections, Binini investigates the conception of (1) possibility as "non-repugnancy with nature" (illustrated by the thesis that "any man can be a bishop" [235]); (2) unrealizable but "conceivable" possibilities (such as the existence of humans lacking the ability to laugh [240]); (3) determinate potencies (like that of an amputee who nevertheless "can walk" [248]); (4) past and counterfactual potencies (like that of a blind person who might be able to see); and (5) other puzzling de re possibilities (such as "irrational humans" [261]).The final...

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Socratic Virtue: Making the Best of the Neither-Good-Nor-BadJ. Clerk ShawNaomi Reshotko. Socratic Virtue: Making the Best of the Neither-Good-Nor-Bad. Cambridge-New York: Cambridge University Press, 2006. Pp. xiv + 204. Cloth, $68.00.In this engaging and provocative book, Naomi Reshotko advances a naturalistic interpretation of Socratic philosophy, i.e., of those views expressed by Plato’s Socrates that best comport with Aristotle’s descriptions of Socrates. She contrasts her reading with those that (...) project foreign commitments onto the text, including: (i) moralism, or the separation of ethics from empirical science; (ii) two-dimensional semantics, or theories of meaning that distinguish the semantic contribution to a psychological state made by its subject’s conception of its objects from that made by its actual objects; and (iii) privileged access, or psychological theories that grant human beings incorrigibility concerning some aspect of their own psyches.Part I reviews and synthesizes views that the author shares with Terry Penner: that all desire is for one’s own real (not apparent) good, so that an agent’s belief about what is overall best for her invariably guides her actions; that all human virtue is identical to wisdom; and that virtue, so understood, guarantees the greatest possible satisfaction of the desire for one’s own real good, and so makes one live as well as possible.Part II places the distinction among the good, the bad, and the neither-good-nor-bad (NGNB) at the center of Socratic ethics. On Reshotko’s reading, the only goods are virtue and happiness, and the only bads vice and misery. She does not adequately explain why all actions are NGNB (16, 173), even though actions are individuated by their actual consequences (34–36), so that every action is either good or bad (98). Virtue’s goodness is due to its stable nomological (not conceptual or logical) connection to happiness. This makes virtue the only unconditional, other-generated good, while happiness is the only unconditional, self-generated good—its goodness does not depend on any nomological relation it enters into.Part III provides more detail about virtue and happiness. First, Reshotko explains that virtue is wisdom because it is the science of human happiness, and that this science is identical to every other science. Strictly speaking, nobody knows anything without knowing everything, although some people do grasp “some parts of knowledge” (160). Reshotko advocates this view as a solution to the closing puzzles of the Charmides. Socrates and Critias cannot figure out how temperance benefits, first because they assume that it is knowledge [End Page 132] of all things except good and bad, and then because they assume that it is knowledge of good and bad in isolation from other sciences (173a–175a). But if Socratic wisdom is the structured grasp of everything, then their puzzle is resolved. Second, Reshotko claims that happiness is a life maximally composed of pleasures. While she is sympathetic with the view that happiness is composed of modal pleasures (see G. Rudebusch, Socrates, Pleasure, and Value, Oxford 1999), she concludes that sensate pleasures can also be parts of happiness (185n7).The book’s major flaw is its limited engagement with textual evidence that seems to tell against the author’s readings and its limited coverage of alternative interpretations from the secondary literature. I mention three striking examples here.First, Reshotko argues that harming others is inconsistent with self-benefit because of the likelihood of reciprocal harm (65–71). She then notes passages where Socrates speaks as though harming others harms one’s soul simply by making it more unjust, which makes vice sound like a self-generated bad. Gorgias 472c–481b is particularly problematic in this respect, since Socrates claims there that doing injustice is less painful (but worse) than suffering it. Reshotko tries to make such passages conform with her initial explanation: harming others tends to entrench false beliefs that harming others is consistent with self-benefit, which leads to more harm of others and so more reciprocal harm (71–72, 174). This may be workable, but absent more extensive argument, it seems like an ad hoc maneuver.Second, Reshotko wants to avoid giving... (shrink)

W. V. Quine is one of the most eminent philosophers alive today. Now in his mid-eighties he has produced a sharp, sprightly book that encapsulates the whole of his philosophical enterprise, including his thinking on all the key components of his epistemological stance--especially the value of logic and mathematics. New readers of Quine may have to go slowly, fathoming for themselves the richness that past readers already know lies between these elegant lines. For the faithful there is much to ponder. (...) In this short book, based on lectures delivered in Spain in 1990, Quine begins by locating his work historically. He provides a lightning tour of the history of philosophy (particularly the history of epistemology), beginning with Plato and culminating in an appreciative sketch of Carnap's philosophical ambitions and achievements. This leads, in the second chapter, to an introduction to Quine's attempt to naturalize epistemology, which emphasizes his continuities with Carnap rather than the differences between them. The next chapters develop the naturalistic story of the development of science to take account of how our conceptual apparatus is enhanced so that we can view the world as containing re-identifiable objects. Having explained the role of observation sentences in providing a checkpoint for assessing scientific theories, and having despaired of constructing an empirical criterion to determine which sentences are meaningful, Quine in the remaining chapters takes up a variety of important issues about knowledge. He concludes with an extended treatment of his views about reference and meaning and his attitudes toward psychological and modal notions. The presentation is distinctive, and the many small refinements of detail and formulation will fascinate all who know Quine's philosophy. (shrink)

_An enlightening introduction to the study of logic: its history, philosophical foundations, and formal structures_ _Logic: Inquiry, Argument, and Order_ is the first book of its kind to frame the study of introductory logic in terms of problems connected to wider issues of knowledge and judgment that arise in the context of racial, cultural, and religious diversity. With its accessible style and integration of philosophical inquiry and real-life concerns, this book offers a novel approach to the theory (...) of logic and its relevance to questions of meaning and value that arise in the world around us. The book poses four problems for logic: Is logic separate from experience? Does logic require dualisms? Can logic reconcile opposed ways of understanding the world? And when things are divided, does the boundary have a logic? The author begins the exploration of these questions with a discussion of the process of analyzing and constructing arguments. Using the logical theories of C. S. Peirce, John Dewey, and Josiah Royce to frame the investigation, subsequent chapters outline the process of inquiry, the concept of communicative action, the nature of validity, categorical reasoning through the theory of the syllogism, and inductive reasoning and probability. The book concludes with a presentation of modal logic, propositional logic, and quantification. Logic is presented as emerging from the activities of inquiry and communication, allowing readers to understand even the most difficult aspects of formal logic as straightforward developments of the process of anticipating and taking action. Numerous practice problems use arguments related to issues of diversity and social theory, and the book introduces methods of proving validity that include Venn diagrams, natural deduction, and the method of tableaux. _Logic: Inquiry, Argument, and Order_ is an ideal book for courses on philosophical methods and critical reasoning at the upper-undergraduate and graduate levels. It is also an insightful reference for anyone who would like to explore a cross-cultural approach to the topic of logic. (shrink)

Any study of the 'Scientific Revolution' and particularly Descartes' role in the debates surrounding the conception of nature (atoms and the void v. plenum theory, the role of mathematics and experiment in natural knowledge, the status and derivation of the laws of nature, the eternality and necessity of eternal truths, etc.) should be placed in the philosophical, scientific, theological, and sociological context of its time. Seventeenth-century debates concerning the nature of the eternal truths such as '2 + 2 (...) = 4' or the law of inertia turn on the question of whether these truths were created along with nature, or were uncreated and subsisting in God's mind. One's answer to that question has direct consequences for conceptions of the necessity/contingency of mathematical and natural knowledge, how knowledge of such truths is accomplished by humans, and what grounds these truths. In this paper, I review the positions of four successors to Descartes' philosophy on the question of the eternal truths to illustrate how in specific ways that question with its theological, metaphysical, modal, and epistemological dimensions concerned the objectivity and certainty of the discoveries of the new science.

Focus Questions Weekly questions can be used to focus the readings. This can be done in a web or e-mail discussion thread, as a weekly assignment, or for in class discussion. I require students to post a short paragraph in response to the question or some posting by a classmate on the question. Students are required to post by 10 a.m. the day before we meet for class on a course website. Week 1: According to Descartes, what role does skepticism play in scientific reasoning? Week 2: Comment on the following: 'But I am supposing this machine to be made by the hands of God, and so I think you may reasonably think it capable of a greater variety of movements than I could possibly imagine in it, and of exhibiting more artistry than I could possibly ascribe to it' [ Treatise on Man ; ATXI 120]. Week 3: What is Descartes' conception of the relation between the metaphysics and physics of nature? Week 4: Critically discuss the positions of Descartes, Malebranche, and Leibniz on what provides the foundation for the certitude of natural knowledge? Week 5: Explain why both Malebranche and Leibniz consider moral sin to be analogous to natural defect? Seminar/Project Idea Hold a debate on the question of the status of the eternal truths. The proposition will be Descartes' position: 'Eternal truths must be both created and necessary if certainty in science is to be possible'. Format: 1. At the beginning of the 5-week module, students will be assigned to one of three roles: Team A, Team B, and judge's panel. Students will be given the debate proposition, but will not be told which team will take the affirmative and which team the negative until the time of the debate. 2. Recommend a variation on the Classic Debate Format to encourage the development of argument: sequence begins with affirmative construction (8 minutes), negative construction (8 minutes), second affirmative construction (8 minutes), second negative construction (8 minutes), first negative rebuttal (4 minutes), first affirmative rebuttal (4 minutes), final negative rebuttal (4 minutes) and final affirmative rebuttal (4 minutes). 3. Judges Panel: will consist of 3–4 judges who will assess the performance of Teams A and B. Judgment should be based on the persuasiveness of the team position. 4. Debate will be held at the end of the fifth week, or semester, whichever makes most sense given the course length and structure.

Further development of the research on the fourteenth-century logic of iterated modalities leads to further exploration in fifteenth- and sixteenth-century Italian scholasticism, in particular, the contributions of Paul of Venice and his followers. The research confirms the well-established notion of “British logic in Italy”, as the major logical strategies used in the analysed works can be traced back to earlier British authors. Logically speaking, the problem of iterated epistemic modalities was framed as debate on the consistency of the hypothesis that (...) an agent doubts whether she knows φ and the hypothesis that an agent knows φ and doubts whether she knows φ, in which the principles of positive and negative introspection play a major part. Philosophically speaking, the debate on the possibility of doubting one’s own knowledge utilised theories of evidence and scientific proof and philosophy of the mind. (shrink)

What if gravity satisfied the Klein-Gordon equation? Both particle physics from the 1920s-30s and the 1890s Neumann-Seeliger modification of Newtonian gravity with exponential decay suggest considering a "graviton mass term" for gravity, which is _algebraic_ in the potential. Unlike Nordström's "massless" theory, massive scalar gravity is strictly special relativistic in the sense of being invariant under the Poincaré group but not the 15-parameter Bateman-Cunningham conformal group. It therefore exhibits the whole of Minkowski space-time structure, albeit only indirectly concerning volumes. (...) Massive scalar gravity is plausible in terms of relativistic field theory, while violating most interesting versions of Einstein's principles of general covariance, general relativity, equivalence, and Mach. Geometry is a poor guide to understanding massive scalar gravity: matter sees a conformally flat metric due to universal coupling, but gravity also sees the rest of the flat metric in the mass term. What is the 'true' geometry, one might wonder, in line with Poincaré's modal conventionality argument? Infinitely many theories exhibit this bimetric 'geometry,' all with the total stress-energy's trace as source; thus geometry does not explain the field equations. The irrelevance of the Ehlers-Pirani-Schild construction to a critique of conventionalism becomes evident when multi-geometry theories are contemplated. Much as Seeliger envisaged, the smooth massless limit indicates underdetermination of theories by data between massless and massive scalar gravities---indeed an unconceived alternative. At least one version easily could have been developed before General Relativity; it then would have motivated thinking of Einstein's equations along the lines of Einstein's newly re-appreciated "physical strategy" and particle physics and would have suggested a rivalry from massive spin 2 variants of General Relativity. The Putnam-Grünbaum debate on conventionality is revisited with an emphasis on the broad modal scope of conventionalist views. Massive scalar gravity thus contributes to a historically plausible rational reconstruction of much of 20th-21st century space-time philosophy in the light of particle physics. An appendix reconsiders the Malament-Weatherall-Manchak conformal restriction of conventionality and constructs the 'universal force' influencing the causal structure. Subsequent works will discuss how massive gravity could have provided a template for a more Kant-friendly space-time theory that would have blocked Moritz Schlick's supposed refutation of synthetic _a priori_ knowledge, and how Einstein's false analogy between the Neumann-Seeliger-Einstein modification of Newtonian gravity and the cosmological constant \Lambda generated lasting confusion that obscured massive gravity as a conceptual possibility.

The paper deals with the main contribution of the Finnish logician Jaakko Hintikka: epistemic logic, in particular the 'static' version of the system based on the formal analysis of the concepts of knowledge and belief. I propose to take a different look at this philosophical logic and to consider it from the opposite point of view of the philosophy of logic. At first, two theories of meaning are described and associated with two competing theories of linguistic competence. In a (...) second step, I draw the conclusion that Hintikka's epistemic logic constitutes a sort of internalisation of meaning, by the introduction of epistemic modal operators into an object language. In this respect, to view meaning as the result of a linguistic competence makes epistemic logic nothing less than a logic of unified meaning and understanding. (shrink)

The article ‘A Note on Strict Implication’ was submitted for publication by C.I. Lewis and C.H. Langford but withdrawn in proof. The paper is, according to notes and letters by both Lewis and Langford, largely by Lewis. It constitutes an early attempt by Lewis to give meanings for the modal connectives using abstract objects. To be necessary, for example, is for a statement to have the same intension as a truth-functional tautology. This theory prefigures the view of Lewis's 1946 (...) book, Analysis of Knowledge and Valuation. This introduction to the article looks at the historical background of the piece in addition to its argument and examines why it was withdrawn. (shrink)

Um dos aspectos característicos da fundamentação epistemológica da etologia de Konrad Lorenz é a tentativa de síntese entre a teoria darwiniana e a gnosiologia kantiana. A partir dessa premissa, delinearemos, antes de tudo, uma breve história da tradição transcendentalista, focalizando a atenção em alguns elementos que seus críticos consideraram insustentáveis. Em segundo lugar, analisaremos a tentativa de Lorenz de implantar a estrutura transcendental em suas pesquisas etológicas, com uma consequente naturalização do conceito de "a priori". Em terceiro lugar, veremos como (...) a atribuição de a priori próprios das espécies particulares abre a possibilidade de interpretar a epistemologia de Lorenz de duas maneiras distintas, aparentemente conflitantes. Finalmente, preferiremos uma dessas interpretações e mostraremos como ela permite o entendimento das distintas modalidades de conhecimento animal e humano. One of the main features of Konrad Lorenz's epistemological foundation of ethology is the attempt of synthesis between Darwinian theory and Kantian gnosiology. Starting from this premise I will outline, first of all, a brief history of transcendentalist tradition, focusing attention on some elements that its critics have regarded as untenable. Secondly, I will analyze Lorenz's attempt to implant the transcendental structure in his ethological researches as being a consequence of the naturalization of the concept of "a priori". Thirdly, I will see how the attribution of a priori proper to single species opens the possibility of interpreting the epistemology of Lorenz in two apparently conflicting ways. Finally, I will prefer one of these interpretations and I will show that it enables us to understand the distinct modalities of animal and human knowledge. (shrink)
