Dieser Band versammelt Texte aus dem Nachlass Moritz Schlicks über den Begriff und die Geschichte der Philosophie. Ein großer Teil davon gehört zum Spätwerk Schlicks, und er plante selbst, sie zu publizieren. Diese Edition macht darum erstmals und im Zusammenhang Texte zugänglich, die noch weitgehend unbekannt sind. Schlick zeichnete darin die Philosophiegeschichte als Geschichte eines Irrtums. Dieser Irrtum wurde von den Eleaten zuerst begangen, indem sie Schein und Sein unterschieden, und wird seither in wechselnder Terminologie wiederholt. Durch die moderne Logik kann dieser Irrtum nach Schlicks Ansicht beseitigt werden.

This book explores some of Kit Fine's outstanding contributions to logic, philosophy of language, philosophy of mathematics, and metaphysics, among others.Contributing authors address in-depth issues about truthmaker semantics, counterfactual conditionals, grounding, vagueness, non-classical consequence relations, and arbitrary objects, offering critical reflections and novel research contributions.Each chapter is accompanied by an extensive commentary, in which Kit Fine offers detailed responses to the ideas and themes raised by the contributors. The book includes a brief autobiography and exhaustive list of his publications to this date. This book is of interest to logicians of all stripes and to analytic philosophers more generally.

This monograph offers a comprehensive study of contingent a priori truths. Building onto a theoretical framework developed by the philosopher and logician Saul Kripke, the author also presents a new approach to these truths. The first part of the book details the many theories on contingent a priori truths. The coverage examines the cases of Kripke and David Kaplan, Donnellan and the de re requirement, Evans and weak contingency, as well as Plantinga, Salmon, Soames, and the pseudo a priori. Overall, it provides a systematic discussion and critical review of all these many positions. Next, the author develops an alternative approach. His working hypothesis is that performative verbs must play a central role in Kripke's examples, even if they do not show up at the surface structure of the corresponding sentences. This opens up an entirely new way of looking at Kripke's cases and of treating them by exploring some aspects of the theory of illocutionary acts. His discussion also examines brute facts and institutional facts, indexicals and performatives, as well as Frege's theory of definitions. Providing an authoritative exploration into contingent a priori truths, this book will be of interest to students, academics, and researchers in philosophy and logic.

This book examines the philosophical and scientific achievements of Sir Kenelm Digby, a successful English diplomat, privateer and natural philosopher of the mid-1600s. Not widely remembered today, Digby is one of the most intriguing figures in the history of early modern philosophers. Among scholars, he is known for his attempt to reconcile what perhaps seem to be irreconcilable philosophical frameworks: Aristotelianism and early modern mechanism.This contributed volume offers the first full-length treatment of Digby's work and of the unique position he occupied in early modern intellectual history. It explores key aspects of Digby's metaphysics, epistemology, and philosophical method, and offers a new appraisal of his contributions to early modern natural philosophy and mathematics.A dozen contributors offer their expert insight into such topics asBody, quantity, and measures in Digby's natural philosophyEcumenism and common notions in DigbyAristotelianism and accidents in Digby's philosophyDigby on body and soulDigby on method and experimentsThis book volume will be of benefit to a broad audience of scholars, educators, and students of the history of early modern science and philosophy.

This book presents a new nominalistic philosophy of mathematics: semantic conventionalism. Its central thesis is that mathematics should be founded on the human ability to create language – and specifically, the ability to institute conventions for the truth conditions of sentences.This philosophical stance leads to an alternative way of practicing mathematics: instead of “building” objects out of sets, a mathematician should introduce new syntactical sentence types, together with their truth conditions, as he or she develops a theory.Semantic conventionalism is justified first through criticism of Cantorian set theory, intuitionism, logicism, and predicativism; then on its own terms; and finally, exemplified by a detailed reconstruction of arithmetic and real analysis.Also included is a simple solution to the liar paradox and the other paradoxes that have traditionally been recognized as semantic. And since it is argued that mathematics is semantics, thissolution also applies to Russell's paradox and the other mathematical paradoxes of self-reference.In addition to philosophers who care about the metaphysics and epistemology of mathematics or the paradoxes of self-reference, this book should appeal to mathematicians interested in alternative approaches.

This book suggests that to know how Wittgenstein's post-Tractarian philosophy could have developed from the work of Kant is to know how they relate to each other. The development from the latter to the former is invoked heuristically as a means of interpretation, rather than a historical process or direct influence of Kant on Wittgenstein. Ritter provides a detailed treatment of transcendentalism, idealism, and the concept of illusion in Kant's and Wittgenstein's criticism of metaphysics. Notably, it is through the conceptions of transcendentalism and idealism that Wittgenstein's philosophy can be viewed as a transformation of Kantianism. This transformation involves a deflationary conception of transcendental idealism along with the abandonment of both the idea that there can be a priori'conditions of possibility'logically detachable from what they condition, and the appeal to an original ‘constitution'of experience. The closeness of Kant and post-Tractarian Wittgenstein does not exist between their arguments or the views they upheld, but rather in their affiliation against forms of transcendental realism and empirical idealism. Ritter skilfully challenges several dominant views on the relationship of Kant and Wittgenstein, especially concerning the cogency of Wittgenstein-inspired criticism focusing on the role of language in the first Critique, and Kant's alleged commitment to a representationalist conception of empirical intuition.

Sortal concepts are at the center of certain logical discussions and have played a significant role in solutions to particular problems in philosophy. Apart from logic and philosophy, the study of sortal concepts has found its place in specific fields of psychology, such as the theory of infant cognitive development and the theory of human perception. In this monograph, different formal logics for sortal concepts and sortal-related logical notions (such as sortal identity and first-order sortal quantification) are characterized. Most of these logics are intensional in nature and possess, in addition, a bidimensional character. That is, they simultaneously represent two different logical dimensions. In most cases, the dimensions are those of time and natural necessity, and, in other cases, those of time and epistemic necessity. Another feature of the logics in question concerns second-order quantification over sortal concepts, a logical notion that is also represented in thelogics. Some of the logics adopt a constant domain interpretation, others a varying domain interpretation of such quantification. Two of the above bidimensional logics are philosophically grounded on predication sortalism, that is, on the philosophical view that predication necessarily requires sortal concepts. Another bidimensional logic constitutes a logic for complex sortal predicates. These three sorts of logics are among the important novelties of this work since logics with similar features have not been developed up to now, and they might be instrumental for the solution of philosophically significant problems regarding sortal predicates. The book assumes a modern variant of conceptualism as a philosophical background. For this reason, the approach to sortal predicates is in terms of sortal concepts. Concepts, in general, are here understood as intersubjective realizable cognitive capacities. The proper features of sortal concepts are determined by an analysisof the main features of sortal predicates. Posterior to this analysis, the sortal-related logical notions represented in the above logics are discussed. There is also a discussion on the extent to which the set-theoretic formal semantic systems of the book capture different aspects of the conceptualist approach to sortals. These different semantic frameworks are also related to realist and nominalist approaches to sortal predicates, and possible modifications to them are considered that might represent those alternative approaches.

In this book, W. V. Quine's Immanuel Kant Lectures entitled Science and Sensibilia are published for the first time in English. These lectures represent an important stage in the development of Quine's later thought, where he is more explicit about the importance of physicalist constraints in his account of the steps from sensory stimulation to scientific theory, and in further using them to assess the extent to which mental vocabulary is defensible. Taken as a unit, these lectures fill an important gap in our understanding of his philosophical development from his 1973 work The Roots of Reference to his later work. The volume further contains an introduction that outlines the content and philosophical significance of the lectures. In addition, several essays written by leading scholars of Quine's philosophy provide further insight into the important issues raised in the lectures.

This edited collection of eight original essays pursues the aim of bringing the spotlight back on Anton Marty. It does so by having leading figures in the contemporary debate confront themselves with Marty's most significative contributions, which span from philosophy of mind, philosophy of language and ontology to meta-metaphysics and meta-philosophy. The book is divided in three parts. The first part is dedicated to themes in philosophy of language, which were at the centre of Marty's philosophical thinking throughout his life. The second part focuses on the problem of the objectivity and phenomenology of time and space, upon which Marty was working in the final years of his life. The final part turns to Marty's meta-metaphysical and meta-philosophical considerations. The intended audience of this book are primarily scholars and students interested in the relevant contemporary debates, as well as scholars working on the Austrian tradition.

This book marks a major new reassessment of Camus's writing investigating the nature and philosophical origins of Camus's thinking on'authenticity'and'the absurd'as these notions are expressed in The Myth of Sisyphus and The Outsider. It shows that these books are the product not only of a literary figure, but of a genuine philosopher as well. Moreover, McBride provides a complete English-language translation of Camus's Mtaphysique chrtienne et Noplatonisme and underlines the importance of this study for the understanding of the early Camus.

XIV The stability of a philosophical construction will depend not only upon the solidity of the blocks, of the pillars and architraves that make it up, but also upon the way in which all these parts are connected. Of course, it will not be possible to argue for every single part of a philosophical building: to do so would mean to embark in a virtually endless enterprise. Accordingly, some of the parts of a philosophical building will have to be taken from the literature on the subject as'ready made'or'semi-finished'elements, while others will be argued for in the course of building. This is what happened in my work too. In some cases (for in­ stance, in the case of epistemic relativism), my concern was to illustrate theses which I believed to be sufficiently consolidated, rather than to ar­ gue for them. In other cases - where I was directly engaged in building the theory that I want to fonnulate - I did exactly the opposite. This is what I have tried to achieve, for example, for those proper architraves of my construction, viz. the connection between scepticism and metaphysi­ cal realism. and the thesis of the nonnative value of the fundamental epistemological notions (truth, objectivity, and rationality).

This book is a historical investigation of the leading philosophical movement in England in the twentieth century. In seven chapters, the intellectual development of the most prominent representatives of analytic philosophy-Moore, Russell and Wittgenstein in Cambridge, and Ryle, Austin, Strawson and Dummett in Oxford-is traced. The book does not aim, however, at delivering a story. This means, above all, that generalisations and conclusions are reduced to a minimum-an approach adopted in an endeavour to avert the danger of subjectivism that interpreting the philosophers under scrutiny would impose. My hope is that by following this aproach, my inves­ tigation will stimulate readers to make their own generalisations and conclusions on the basis of the objectively presented data. Instead, my aim is to articulate a flawless, comprehensive description of the phil­ osophical texts of the seven most significant analytic philosophers in England in the twentieth century. For this purpose, all their articles and books have been sifted through in order to pick out the most representative parts. For obvious reasons, only the chapters on Russell and Wittgenstein, and-to a lesser extent-the chapter on Moore, are more theoretical.

In The Natural Background to Meaning Denkel argues that meaning in language is an outcome of the evolutionary development of forms of animal communication, and explains this process by naturalising the Locke-Grice approach. The roots of meaning are contained in observable regularities, which are manifestations of objective connections such as essences and causal relations. Denkel's particularistic ontology of properties and causation leads to a view of time that harmonises B-theory with transience. Time's passage, he argues, is a necessary condition of communication and meaning. The book connects some central topics in the philosophies of language, science and ontology, treating them within the framework of a single theory. It will interest not only professional philosophers doing research on meaning, universals, causation and time, but also students, who can consult it as a textbook examining Grice's theory of meaning.

This collection of essays presents a systematic and up-to-date survey of the main aspects of Georg Henrik von Wright's philosophy, tracing the general humanistic leitmotiv to be found in his vast, varied output. The analysis covers the developments in Von Wright's thought up to the end of the 1990s. The essays are arranged thematically to focus on the chief areas of Von Wright's interests: practical rationality; human action and determinism; philosophical logic and theories of norms; research in the analytical tradition; and Wittgenstein studies. Readership: Scholars and students of moral philosophy, logic, psychology, sociology, cognitive science and the history of contemporary philosophy.

Willard VanOrman Quine has probably been the most influential th American philosopher of the 20 century. His work spans over seven decades, and covers many domains in philosophy. He has made major contributions to the fields of logic and set theory, philosophy of logic and mathematics, philosophy of language, philosophy of science, epistemology and metaphysics. Quine's first work in philosophy was in the field of logic. His major contributions are the two set-theoretic systems NF (1936) and ML (1940). 1 These systems were alternatives to the type theory of Principia Mathematica or Zermelo's set theory, and are still being studied by 2 mathematicians. An indirect contribution to the field of logic is his strong resistance to moda110gic. Quine's objectIons to the notions of necessity and analyticity have influenced the development of moda110gic? Quine has had an enormous influence on philosophy of mathematics. When Quine entered philosophy there was a discussion on the foundations of mathematics between the schools of intuitionism, formalism, and conventionalism. Quine soon took issue with Carnap's conventionalism in'Truth by convention,,4 (1936). Quine has never joined one of the other schools, but has added new elements that are the basic ones of the 5 contemporary schools of nominalism, platonism, and structuralism. Quine has long been in the shadow of Benacerraf and Putnam in this field. At the moment there seems to be a renewed interest in Quine's work, and most philosophers explicitly refer to Quine's work.

1. HISTORICAL BACKGROUND The purpose of the book is to develop internal realism, the metaphysical-episte­ mological doctrine initiated by Hilary Putnam (Reason, Truth and History,'Introduction', Many Faces). In doing so I shall rely - sometimes quite heavily - on the notion of conceptual scheme. I shall use the notion in a somewhat idiosyncratic way, which, however, has some affinities with the ways the notion has been used during its history. So I shall start by sketching the history of the notion. This will provide some background, and it will also give opportunity to raise some of the most important problems I will have to solve in the later chapters. The story starts with Kant. Kant thought that the world as we know it, the world of tables, chairs and hippopotami, is constituted in part by the human mind. His cen­ tral argument relied on an analysis of space and time, and presupposed his famous doctrine that knowledge cannot extend beyond all possible experience. It is a central property of experience - he claimed - that it is structured spatially and temporally. However, for various reasons, space and time cannot be features of the world, as it is independently of our experience. So he concluded that they must be the forms of human sensibility, i. e. necessary ingredients of the way things appear to our senses.

Andrea Bottani Massimiliano Carrara Pierdaniele Giaretta What do we do when we do metaphysics? The aim of this introduction is to give a provisional answer to this question, and then to explain the subtitle of the volume. It is easy to observe that when we do meta­ physics we engage in a linguistic activity, mainly consisting of uttering declarative sentences that are not very clear to most people. That is true, but, of course, it is not very informative. What do we speak of when we do metaphysics? A traditional answer could be: we speak of what things really are, so suggesting that things can appear in a way that is different from the way they really are. So understood, meta­ physics is about the sense, or the senses, of'real being'. A question that immediately arises is whether the sense of being is unique or is different for different types of things. Another question is whether it is possible that something could appear to be, but really not be. Modem analytic metaphysicians usually answer that the sense of being is unique, while acknowledging that there are different kinds of things, and that to say that something could appear to be but really not be is a plain contradiction, unless what is understood is that it could appear to us that there is something having such and such features, but viii Individuals, Essence, and Identity really there is no such a thing.

Incommensurability and Related Matters draws together some of the most distinguished contributors to the critical literature on the problem of the incommensurability of scientific theories. It addresses all the various problems raised by the problem of incommensurability, such as meaning change, reference of theoretical terms, scientific realism and anti-realism, rationality of theory choice, cognitive aspects of conceptual change, as well as exploring the broader implications of incommensurability for cultural difference. While it offers new work, and new directions of discussion, on the topic of incommensurability, the book also recapitulates the history of the discussion of the topic that has taken place within the literature on incommensurability.

Many articles and books dealing with Donald Davidson's philosophy are dedicated to the papers and ideas Davidson put forward in the `sixties and `seventies. In the last two decades, however, Davidson has continued to work in many areas of philosophy, offering new contributions, many of which are highly regarded by philosophers working in the fields concerned. For instance, Davidson has considerably developed his ideas about interpretation, theory of meaning, irreducibility of the mental, causation, and action theory; he has proposed an innovative externalist conception of the mental content and a new analysis of the concept of truth; and he has partly modified his theses about event, and the supervenience of the mental on the physical. In Interpretations and Causes, some of the leading contemporary analytic philosophers discuss Davidson's new ideas in a lively, relevant, useful, and not always entirely sympathetic way. Davidson himself offers and original contribution.

Some time ago I wrote a book (Moral Language, 1982) in which I argued that moral judgments are capable of being true ('truth-apt,'to use a current phrase, or descriptive and having truth-value, to use a more traditional term), that the methods of discovering moral facts are fundamentally similar to those of discovering non-moral facts, and that moral judgments may be true. What I did not do at that time was to develop a moral theory which would demonstrate how the method of discovering moral truths would work and what the criteria of truth actually are. In a later work (Persons, Animals, and Fetuses, 1996) I did propose a moral theory as to what the criteria for moral truth are; however, I presented it primarily as an introduction to the discussion of several practical ethical issues and did not argue fully for that theory. It is high time that I did so, because without showing that such a theory can be developed my defense of moral realism is incomplete. It is all very well to say that we can discover what moral beliefs are true, but unless we can demonstrate just which beliefs are true, the thesis that we can discover this truth cannot be fully defended. For this reason the biggest (although not the only) challenge to showing that ethical objectivity is possible is the presence of moral disagreement - and the contention of many that such disagreement cannot be definitively resolved.

Wittgenstein was a faithful and passionate reader of Plato's Dialogues as confirmed by writings and witnesses. Here well-known scholars of Wittgenstein and Plato illuminate the relationship between the two philosophers both philologically and philosophically, and provide new interpretation keys of two of the leading figures of Western thought.

The subject of this book is the first person in thought and language. The main question concerns what we mean when we say'J'. Related to it are questions about what kinds of self-consciousness and self-knowledge are needed in order for us to have the capacity to talk about ourselves. The emphasis is on theories of meaning and reference for'J', but a fair amount of space is devoted to'I'-thoughts and the role of the concept of the self in cognition. The purpose is to give a picture of how we think and talk about ourselves in a wide range of circumstances. The topic has been discussed in numerous articles during the last decades, but rarely in the form of a monograph. I felt the need for a book of this kind while working on my dissertation. The manuscript is the result of many years of reflection on the self and indexicals. Some of the theories that I advance have developed as a result of my teaching an undergraduate course in the philosophy of language the last couple of years.
