This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

Graham Priest presents a ground-breaking account of the semantics of intentional language--verbs such as "believes," "fears," "seeks," or "imagines." Towards Non-Being proceeds in terms of objects that may be either existent or non-existent, at worlds that may be either possible or impossible. The book will be of central interest to anyone who is concerned with intentionality in the philosophy of mind or philosophy of language, the metaphysics of existence and identity, the philosophy of fiction, the philosophy of mathematics, or cognitive (...) representation in AI.

This two-volume work, first published in 1843, was John Stuart Mill's first major book. It reinvented the modern study of logic and laid the foundations for his later work in the areas of political economy, women's rights and representative government. In clear, systematic prose, Mill disentangles syllogistic logic from its origins in Aristotle and scholasticism and grounds it instead in processes of inductive reasoning. An important attempt at integrating empiricism within a more general theory of human knowledge, the work constitutes (...) essential reading for anyone seeking a full understanding of Mill's thought. Continuing the discussion of induction, Volume 2 concludes with Book VI, 'On the Logic of the Moral Sciences', in which Mill applies empirical reasoning to human behaviour. A crucial early formulation of his thinking regarding free will and necessity, this book establishes the centrality of 'the social science' to Mill's philosophy. (shrink)

Thomas Reid was a philosopher who founded the Scottish school of 'common sense'. Much of Reid's work is a critique of his contemporary, David Hume, whose empiricism he rejects. In this work, written after Reid's appointment to a professorship at the university of Glasgow, and published in 1785, he turns his attention to ideas about perception, memory, conception, abstraction, judgement, reasoning and taste. He examines the work of his predecessors and contemporaries, arguing that 'when we find philosophers maintaining that there (...) is no heat in the fire, nor colour in the rainbow … we may be apt to think the whole to be only a dream of fanciful men, who have entangled themselves in cobwebs spun out of their own brain'. Written by one of the Scottish Enlightenment's most important thinkers, this work brings to life the intellectual debates of the time. (shrink)

This second edition features a new 48-page Afterword--1980 updating Professor Beardsley's classic work.

The distinction between a type and its tokens is a useful metaphysical distinction. In §1 it is explained what it is, and what it is not. Its importance and wide applicability in linguistics, philosophy, science and everyday life are briefly surveyed in §2. Whether types are universals is discussed in §3. §4 discusses some other suggestions for what types are, both generally and specifically. Is a type the sets of its tokens? What exactly is a word, a symphony, a species? (...) §5 asks what a token is. §6 considers the relation between types and their tokens. Do the type and all its tokens share the same properties? Must all the tokens be alike in some or all respects? §7 explains some problems for the view that types exist, and some problems for the view that they don't. §8 elucidates a distinction often confused with the type-token distinction, that between a type (or token) and an occurrence of it. It also discusses some problems that occurrences might be thought to give rise to, and one way to resolve them. (shrink)

The mathematical theory of communication.

Written over the last two decades, John McDowell's papers, as a whole, deal with issues of philosophy. Specifically, separate groups of essays look at the ethical writings of Aristotle and Plato; moral questions regarding the Greek tradition; interpretations of Wittgenstein's work; and, finally, questions about personal identity and the character of first-person thought and speech.

Immanuel Kant was one of the leading lights of 18th-century philosophy; his work provided the foundations for later revolutionary thinkers such as Hegel and Marx. This work contains the keystone of his critical philosophy - the basis of human knowledge and truth.

The classic, influential essay in 'descriptive metaphysics' by the distinguished English philosopher.

Over 700,000 copies of the original hardcover and paperback editions of this stunningly popular book have been sold. Karen Armstrong's superbly readable exploration of how the three dominant monotheistic religions of the world—Judaism, Christianity, and Islam—have shaped and altered the conception of God is a tour de force. One of Britain's foremost commentators on religious affairs, Armstrong traces the history of how men and women have perceived and experienced God, from the time of Abraham to the present. From classical philosophy (...) and medieval mysticism to the Reformation, the Enlightenment, and the modern age of skepticism, Armstrong performs the near miracle of distilling the intellectual history of monotheism into one compelling volume.

Thomas S. Kuhn's classic book is now available with a new index.

This 1997 book was the first English translation of all of Kant's writings on moral and political philosophy collected in a single volume. No other collection competes with the comprehensiveness of this one. As well as Kant's most famous moral and political writings, the Groundwork of the Metaphysics of Morals, the Critique of Practical Reason, the Metaphysics of Morals, and Toward Perpetual Peace, the volume includes shorter essays and reviews, some of which have never been translated before. The volume has (...) been furnished with a substantial editorial apparatus including translator's introductions and explanatory notes to each text by Mary Gregor, and a general introduction to Kant's moral and political philosophy by Allen Wood. There is also an English-German and German-English glossary of key terms. (shrink)

This book tackles the issues that arise in connection with intensional logic -- a formal system for representing and explaining the apparent failures of certain important principles of inference such as the substitution of identicals and existential generalization -- and intentional states --mental states such as beliefs, hopes, and desires that are directed towards the world. The theory offers a unified explanation of the various kinds of inferential failures associated with intensional logic but also unifies the study of intensional contexts (...) and intentional states by grounding the explanation of both phenomena in a single theory. When an axiomatized realm of abstract entities is added to the metaphysical structure of the world, we can use them to identify and individuate the contents of directed mental states. The special abstract entities can be viewed as the objectified contents of mental files, and they play a crucial role in the analysis of truth conditions of the sentences involved in inferential failures.

In this book, Zalta attempts to lay the axiomatic foundations of metaphysics by developing and applying a (formal) theory of abstract objects. The cornerstones include a principle which presents precise conditions under which there are abstract objects and a principle which says when apparently distinct such objects are in fact identical. The principles are constructed out of a basic set of primitive notions, which are identified at the end of the Introduction, just before the theorizing begins. The main reason for (...) producing a theory which defines a logical space of abstract objects is that it may have a great deal of explanatory power. It is hoped that the data explained by means of the theory will be of interest to pure and applied metaphysicians, logicians and linguists, and pure and applied epistemologists. (shrink)

Sherlock Holmes is a fictional individual. So is his favorite pipe. Our pre-theoretical intuition says that neither of them is real. It says that neither of them really, or actually, exists. It also says that there is a sense in which they do exist, namely, a sense in which they exist “in the world of” the Sherlock Holmes stories. Our pre-theoretical intuition says in general of any fictional individual that it does not actually exist but exists “in the world of” (...) the relevant fiction. I wish to defend this pretheoretical intuition. To do so, I need to defend two claims: that fictional individuals do not actually exist, and that they exist “in the world of” the relevant fiction. The aim of this paper is to defend the first claim. (shrink)

A good phenomenological theory must be able to account equally well for our experiences of veridical perception and hallucination, for our thoughts about universities, colors, numbers, mythical figures and more. For all of these are characteristic mental acts, and a theory of intentionality should be a theory of conscious acts in general, not just of consciousness of a specific kind of thing or of a specific kind of consciousness. In so far as phenomenology purports to be a general study of (...) intentional acts of consciousness, it must be able to account for acts with all kinds of objects and with all kinds of thetic character. Any limitation of these features puts the theory in danger of being an explanation of only some kinds of mental act, and of mis-characterizing the nature of intentionality in general. (shrink)

I argue that the ontological status of fictional characters is determined by the beliefs and practices of those who competently deal with works of literature, and draw out three important consequences of this. First, heavily revisionary theories cannot be considered as ‘discoveries’ about the ‘true nature’ of fictional characters; any acceptable realist theory of fiction must preserve all or most of the common conception of fictional characters. Second, once we note that the existence conditions for fictional characters are extremely minimal, (...) it makes little sense to deny the existence of fictional characters, leaving anti-realist views of fiction unmotivated. Finally, the role of ordinary beliefs and practices in determining facts about the ontology of fictional characters explains why non-revisionary theories of fiction are bound to yield no determinate or precise answer to certain questions about fictional characters, demonstrating the limits of a theory of fiction.

By a `denoting phrase' I mean a phrase such as any one of the following: a man, some man, any man, every man, all men, the present King of England, the present King of France, the center of mass of the solar system at the first instant of the twentieth century, the revolution of the earth round the sun, the revolution of the sun round the earth. Thus a phrase is denoting solely in virtue of its form. We may distinguish (...) three cases: (1) A phrase may be denoting, and yet not denote anything; e.g., `the present King of France'. (2) A phrase may denote one definite object; e.g., `the present King of England' denotes a certain man. (3) A phrase may denote ambiguously; e.g. `a man' denotes not many men, but an ambiguous man. The interpretation of such phrases is a matter of considerably difficulty; indeed, it is very hard to frame any theory not susceptible of formal refutation. All the difficulties with which I am acquainted are met, so far as I can discover, by the theory which I am about to explain. (shrink)

Modern empiricism has been conditioned in large part by two dogmas. One is a belief in some fundamental cleavage between truths which are analytic, or grounded in meanings independently of matters of fact, and truth which are synthetic, or grounded in fact. The other dogma is reductionism: the belief that each meaningful statement is equivalent to some logical construct upon terms which refer to immediate experience. Both dogmas, I shall argue, are ill founded. One effect of abandoning them is, as (...) we shall see, a blurring of the supposed boundary between speculative metaphysics and natural science. Another effect is a shift toward pragmatism. (shrink)

In this fascinating autobiography from the foremost genius of twentieth-century physics, Max Planck tells the story of his life, his aims, and his thinking. Published posthumously, the papers in this volume were written for the general reader and make accessible his scientific theories as well as his philosophical ideals, including his thoughts on ethics and morals. Max (Karl Ernst Ludwig) Planck was a German physicist and philosopher known for his quantum theory, for which he won the Nobel Prize in Physics (...) in 1918. Planck was born in Kiel, Germany, in 1858 to an academic family, and he valued education from a young age. He attended the Universities of Munich and Berlin to study physics under the great scientific leaders Kirchhoff and Helmholtz. His early work mainly focused on the study of thermodynamics, and in 1900 he published a paper on his quantum theory that would change the face of modern physics. Planck worked as a professor at Berlin University his entire life, and he also served as the president of the Kaiser Wilhelm Society for the Promotion of Science. During World War II, Planck experienced great hardships while he remained in Germany but openly opposed the Nazi regime. One of his two sons was executed during this time for an unsuccessful attempt on Hitler's life, and Planck's home in Berlin was eventually bombed. He continued to write on physics and philosophy until his death in 1947. (shrink)

This book is in three sections, with two chapters in each. It begins with questions of psychology: questions to do with what it means to be an intentional agent and, in particular, what it means to be an agent with the capacity for thought. Having sketched an overall view of the intentional, thinking agent, it then goes on to explore the difference that social life makes to the mentality of such agents; in effect, it outlines a social ontology. And, having (...) developed a picture of the mind in society – of the common or social mind – it turns, finally, to the lessons of this picture for the pursuit of social and political theory: for the explanation of what happens on the social scene and for the evaluation of the different ways in which that scene may be structured.

Pettit presents a selection of essays touching upon metaphysics, philosophical psychology, and the theory of rational regulation. The first part of the book discusses the rule-following character of thought. The second considers how choice can be responsive to different sorts of factors, while still being under the control of thought. The third examines the implications of this view of choice and rationality for the normative regulation of social behavior.

In this book Terence Parsons revives the older tradition of taking such objects at face value. Using various modern techniques from logic and the philosophy of language, he formulates a metaphysical theory of nonexistent objects. The theory is given a formalization in symbolism rich enough to contain definite descriptions, modal operators, and epistemic contexts, and the book includes a discussion which relates the formalized theory explicitly to English.

The main puzzle about theoretical definitions is that nothing seems to decide which assumptions contribute to such definitions and which do not. I argue that theoretical definitions are indeed imprecise, but that this does not normally matter, since the definitional imprecision does not normally produce indeterminacy of referential value. Sometimes, however, the definitional imprecision is less benign, and does generate referential indeterminacy. In these special cases, but not otherwise, it is necessary to refine the term's definition.

In the first half of this book, I offer a theory of fictional content or, as it is sometimes known, ‘fictional truth’.The theory of fictional content I argue for is ‘extreme intentionalism’. The basic idea – very roughly, in ways which are made precise in the book - is that the fictional content of a particular text is equivalent to exactly what the author of the text intended the reader to imagine. The second half of the book is concerned with (...) showing how extreme intentionalism and the lessons learnt from it can illuminate cognate questions in the philosophy of fiction and imagination. For instance, I argue, my position helps us to explain how fiction can provide us with reliable testimony ; it helps explain the phenomenon of imaginative resistance ; and it fits with, and so supports, a persuasive theory of the nature of fiction itself. In my final chapter, I show how attending to intentionalist practices of interpreting fictional content can illuminate the nature of propositional imagining itself. (shrink)

This paper presents a novel explanandum for a theory of fictional truth. I explore a range of theoretical treatments of the data, and argue that it motivates the adoption of a distinctive style of relativism about truth-in-fiction.

In Art and intention Paisley Livingston develops a broad and balanced perspective on perennial disputes between intentionalists and anti-intentionalists in philosophical aesthetics and critical theory. He surveys and assesses a wide range of rival assumptions about the nature of intentions and the status of intentionalist psychology. With detailed reference to examples from diverse media, art forms, and traditions, he demonstrates that insights into the multiple functions of intentions have important implications for our understanding of artistic creation and authorship, the ontology (...) of art, conceptions of texts, works, and versions, basic issues pertaining to the nature of fiction and fictional truth, and the theory of art interpretation and appreciation. Livingston argues that neither the inspirationist nor rationalistic conceptions can capture the blending of deliberate and intentional, spontaneous and unintentional processes in the creation of art. Texts, works, and artistic structures and performances cannot be adequately individuated in the absence of a recognition of the relevant makers4intentions. The distinction between complete and incomplete works receives an action-theoretic analysis that makes possible an elucidation of several different senses of "fragment" in critical discourse. Livingston develops an account of authorship, contending that the recognition of intentions is in fact crucial to our understanding of diverse forms of collective art-making. An artist's short-term intentions and long-term plans and policies interact in complex ways in the emergence of an artistic oeuvre, and our uptake of such attitudes makes an important difference to our appreciation of the relations between items belonging to a single life-work. The intentionalism Livingston advocates is, however, a partial one, and accommodates a number of important anti-intentionalist contentions. Intentions are fallible, and works of art, like other artefacts, can be put to a bewildering diversity of uses. Yet some important aspects of art's meaning and value are linked to the artist's aims and activities. (shrink)

This book examines the complex and varied ways in which fictions relate to the real world, and offers a precise account of how imaginative works of literature can use fictional content to explore matters of universal human interest. While rejecting the traditional view that literature is important for the truths that it imparts, the authors also reject attempts to cut literature off altogether from real human concerns. Their detailed account of fictionality, mimesis, and cognitive value, founded on the methods of (...) analytical philosophy, restores to literature its distinctive status among cultural practices. The authors also explore metaphysical and skeptical views, prevalent in modern thought, according to which the world itself is a kind of fiction, and truth no more than a social construct. They identify different conceptions of fiction in science, logic, epistemology, and make-believe, and thereby challenge the idea that discourse per se is fictional and that different modes of discourse are at root indistinguishable. They offer rigorous analyses of the roles of narrative, imagination, metaphor, and "making" in human thought processes. Both in their methods and in their conclusions, Lamarque and Olsen aim to restore rigor and clarity to debates about the values of literature, and to provide new, philosophically sound foundations for a genuine change of direction in literary theorizing.

One of the cornerstone books of Western philosophy, Critique of Pure Reason is Kant's seminal treatise, where he seeks to define the nature of reason itself and builds his own unique system of philosophical thought with an approach known as transcendental idealism. He argues that human knowledge is limited by the capacity for perception and attempts a logical designation of two varieties of knowledge: a posteriori, the knowledge acquired through experience; and a priori, knowledge not derived through experience. This accurate (...) translation by J. M. D. Meiklejohn offers a simple and direct rendering of Kant's work that is suitable for readers at all levels. (shrink)
