What is truth? Michael Lynch defends a bold new answer to this question. Traditional theories of truth hold that truth has only a single uniform nature. All truths are true in the same way. More recent deflationary theories claim that truth has no nature at all; the concept of truth is of no real philosophical importance. In this concise and clearly written book, Lynch argues that we should reject both these extremes and hold that truth is a functional property. To understand truth we must understand what it does, its function in our cognitive economy. Once we understand that, we'll see that this function can be performed in more than one way. And that in turn opens the door to an appealing pluralism: beliefs about the concrete physical world needn't be true in the same way as our thoughts about matters -- like morality -- where the human stain is deepest.

Barry Stroud's work has had a profound impact on a very wide array of philosophical topics, including epistemological skepticism, the nature of logical necessity, the interpretation of Hume, the interpretation of Wittgenstein, the possibility of transcendental arguments, and the metaphysical status of color and value. And yet there has heretofore been no book-length treatment of his work. The current collection aims to redress this gap, with 13 essays on Stroud's work by a diverse group of contributors including some of his most distinguished interlocutors and promising recent students. All but one essay is new to this volume.
The essays cover a range of topics, with a particular focus on Stroud's treatments of skepticism and subjectivism. There are also chapters on Stroud's views on meaning and rule-following, on Hume on personal identity, and on the role of desires in the explanation of action. Despite the diversity, the essays are unified by the thematic unity in Stroud's own writings. Stroud approaches every philosophical problem by attempting to get as clear as possible on the nature and source of that problem. He aims to determine what kind of understanding philosophical questions are after, and what the prospects for achieving that understanding might be. This theme--of the nature and possibility of philosophical understanding--is introduced in the opening essay of this volume and recurs in different ways throughout the remaining chapters.
In recent years, there has been a renewed interest in the philosophy of philosophy. As these essays show, one important source of insight on this subject is the thought of Barry Stroud, for whom pursuit of the philosophy of philosophy has always been indistinguishable from pursuit of philosophy as such.

Doing and Being confronts the problem of how to understand two central concepts of Aristotle's philosophy: energeia and dunamis. While these terms seem ambiguous between actuality/potentiality and activity/capacity, Aristotle did not intend them to be so. Through a careful and detailed reading of Metaphysics Theta, Beere argues that we can solve the problem by rejecting both "actuality" and "activity" as translations of energeia, and by working out an analogical conception of energeia. This approach enables Beere to discern a hitherto unnoticed connection between Plato's Sophist and Aristotle's Metaphysics Theta, and to give satisfying interpretations of the major claims that Aristotle makes in Metaphysics Theta, the claim that energeia is prior in being to capacity (Theta 8) and the claim that any eternal principle must be perfectly good (Theta 9).

During the seventeenth century Francisco Suarez was considered one of the greatest philosophers of the age. He was the last great Scholastic thinker and profoundly influenced the thought of his contemporaries within both Catholic and Protestant circles. Suarez contributed to all fields of philosophy, from natural law, ethics, and political theory to natural philosophy, the philosophy of mind, and philosophical psychology, and-most importantly-to metaphysics, and natural theology. Echoes of his thinking reverberate through the philosophy of Descartes, Locke, Leibniz, and beyond. Yet curiously Suarez has not been studied in detail by historians of philosophy. It is only recently that he has emerged as a significant subject of critical and historical investigation for historians of late medieval and early modern philosophy. Only in recent years have small sections of Suarez's magnum opus, the Metaphysical Disputations, been translated into English, French, and Italian. The historical task of interpreting Suarez's thought is still in its infancy. The Philosophy of Francisco Suarez is one of the first collections in English written by the leading scholars who are largely responsible for this new trend in the history of philosophy. It covers all areas of Suarez's philosophical contributions, and contains cutting-edge research which will shape and frame scholarship on Suarez for years to come-as well as the history of seventeenth-century generally. This is an essential text for anyone interested in Suarez, the seventeenth-century world of ideas, and late Scholastic or early modern philosophy.

To what extent are meaning, on the one hand, and knowledge, on the other, determined by aspects of the 'outside world'? Internalism and Externalism in Semantics and Epistemology presents twelve specially written essays exploring these debates in metaphysics and epistemology and the connections between them. In so doing, it examines how issues connected with the nature of mind and language bear on issues about the nature of knowledge and justification (and vice versa). Topics discussed include the compatibility of semantic externalism and epistemic internalism, the variety of internalist and externalist positions (both semantic and epistemic), semantic externalism's implications for the epistemology of reasoning and reflection, and the possibility of arguments from the theory of mental content to the theory of epistemic justification (and vice versa).

Reference is a central topic in philosophy of language, and has been the main focus of discussion about how language relates to the world. R. M. Sainsbury sets out a new approach to the concept, which promises to bring to an end some long-standing debates in semantic theory. There is a single category of referring expressions, all of which deserve essentially the same kind of semantic treatment. Included in this category are both singular and plural referring expressions ('Aristotle', 'The Pleiades'), complex and non-complex referring expressions ('The President of the USA in 1970', 'Nixon'), and empty and non-empty referring expressions ('Vulcan', 'Neptune'). Referring expressions are to be described semantically by a reference condition, rather than by being associated with a referent. In arguing for these theses, Sainsbury's book promises to end the fruitless oscillation between Millian and descriptivist views. Millian views insist that every name has a referent, and find it hard to give a good account of names which appear not to have referents, or at least are not known to do so, like ones introduced through error ('Vulcan'), ones where it is disputed whether they have a bearer ('Patanjali') and ones used in fiction. Descriptivist theories require that each name be associated with some body of information. These theories fly in the face of the fact names are useful precisely because there is often no overlap of information among speakers and hearers. The alternative position for which the book argues is firmly non-descriptivist, though it also does not require a referent. A much broader view can be taken of which expressions are referring expressions: not just names and pronouns used demonstratively, but also some complex expressions and some anaphoric uses of pronouns. Sainsbury's approach brings reference into line with truth: no one would think that a semantic theory should associate a sentence with a truth value, but it is commonly held that a semantic theory should associate a sentence with a truth condition, a condition which an arbitrary state of the world would have to satisfy in order to make the sentence true. The right analogy is that a semantic theory should associate a referring expression with a reference condition, a condition which an arbitrary object would have to satisfy in order to be the expression's referent. Lucid and accessible, and written with a minimum of technicality, Sainsbury's book also includes a useful historical survey. It will be of interest to those working in logic, mind, and metaphysics as well as essential reading for philosophers of language.

Not all scientific explanations work by describing causal connections between events or the world's overall causal structure. Some mathematical proofs explain why the theorems being proved hold. In this book, Marc Lange proposes philosophical accounts of many kinds of non-causal explanations in science and mathematics. These topics have been unjustly neglected in the philosophy of science and mathematics. One important kind of non-causal scientific explanation is termed explanation by constraint. These explanations work by providing information about what makes certain facts especially inevitable - more necessary than the ordinary laws of nature connecting causes to their effects. Facts explained in this way transcend the hurly-burly of cause and effect. Many physicists have regarded the laws of kinematics, the great conservation laws, the coordinate transformations, and the parallelogram of forces as having explanations by constraint. This book presents an original account of explanations by constraint, concentrating on a variety of examples from classical physics and special relativity. This book also offers original accounts of several other varieties of non-causal scientific explanation. Dimensional explanations work by showing how some law of nature arises merely from the dimensional relations among the quantities involved. Really statistical explanations include explanations that appeal to regression toward the mean and other canonical manifestations of chance. Lange provides an original account of what makes certain mathematical proofs but not others explain what they prove. Mathematical explanation connects to a host of other important mathematical ideas, including coincidences in mathematics, the significance of giving multiple proofs of the same result, and natural properties in mathematics. Introducing many examples drawn from actual science and mathematics, with extended discussions of examples from Lagrange, Desargues, Thomson, Sylvester, Maxwell, Rayleigh, Einstein, and Feynman, Because Without Cause's proposals and examples should set the agenda for future work on non-causal explanation.

Gary Kemp presents a penetrating investigation of key issues in the philosophy of language, by means of a comparative study of two great figures of late twentieth-century philosophy. So far as language and meaning are concerned, Willard Van Orman Quine and Donald Davidson are usually regarded as birds of a feather. The two disagreed in print on various matters over the years, but fundamentally they seem to be in agreement; most strikingly, Davidson's thought experiment of Radical Interpretation looks to be a more sophisticated, technically polished version of Quinean Radical Translation. Yet Quine's most basic and general philosophical commitment is to his methodological naturalism, which is ultimately incompatible with Davidson's main commitments. In particular, it is impossible to endorse, from Quine's perspective, the roles played by the concepts of truth and reference in Davidson's philosophy of language: Davidson's employment of the concept of truth is from Quine's point of view needlessly adventurous, and his use of the concept of reference cannot be divorced from unscientific 'intuition'. From Davidson's point of view, Quine's position looks needlessly scientistic, and seems blind to the genuine problems of language and meaning. Gary Kemp offers a powerful argument for Quine's position, and in favour of methodological naturalism and its corollary, naturalized epistemology. It is possible to give a consistent and explanatory account of language and meaning without problematic uses of the concepts truth and reference, which in turn makes a strident naturalism much more plausible.

Is everything just as it should be, or is the world spiraling out of control and we must try to save it? Is life simple, once we understand how it works, or is it so complicated only a nuclear physicist could understand it? The authors claim that life is simple, but only if we accept what we encounter with equanimity and are willing to replace old ideas with new ones that make more sense. Attachment, resistance, and emotional reactions are what make life difficult. Is there a personal God? Does Satan exist? Do politics have a role in the spiritual development of our world? What part does sex play in our spiritual development? This is not a "safe" book. The authors have answers for all these questions and more, but not all readers will agree with them. And that is as it should be, according to them. Their concepts of how life works, based on Ancient Wisdom teachings, will make you analyze, ponder over, and re-assess your entire belief system. The overall message is one of assurance. As one reader said, "It gave me hope. I never considered myself a spiritual person until I read this book." "This book speaks in today's language to seekers of all ages. Whether a seasoned student or a beginner, it opens new doors and fresh vistas on the soul's journey to wisdom. It is indeed a practical guide, at the same time surveying all the principles necessary for understanding the wisdom-tradition we know as Theosophy. This book brings the Ancient Wisdom into the 21st century " - Joy Mills, author of Reflections on an Ancient Wisdom "Ancient Wisdom for a New Age provides some very important advice for those who want to live the spiritual life. The chapter on reincarnation is especially well-done. Hunt and Benedict are to be commended for making a noble effort to help spiritual pilgrims on their way. By far the most practical chapter in the book is 'Your Spiritual Practice'." - Quest Magazine

In this book Douglas Ehring shows the inadequacy of received theories of causation and, introducing conceptual devices of his own, provides a wholly new account of causation as the persistence over time of individual properties, or "tropes".

This renowned introduction - already a standard text in Europe - is translated here for the first time. Vattimo uses Heideggerean and cultural-critical perspectives to reassess the work and thought of Nietzsche.

Die Philosophie wurde von so unterschiedlichen Philosophen wie Wolff und Russell als Moglichkeitswissenschaft bezeichnet. Doch erwiesen sich die modalen Konzepte von Moglichkeit und Notwendigkeit als sperrig und vieldeutig, und ihr Verhaltnis zum Wirklichkeitsbegriff bleibt problematisch. Die vorliegende Sammlung beleuchtet die Metaphysik und Logik von Moglichkeit und Wirklichkeit aufs Neue und betrachtet sie aus unterschiedlichsten Perspektiven jenseits der Dichotomie von analytischer und kontinentaler Philosophie. Die Philosophiegeschichte (von der griechischen Antike bis zu David Lewis) kommt ebenso zu Wort wie die Semantik moglicher Welten; Logik, Mathematik und Computerwissenschaft ebenso wie Literatur und Neue Medien; Formen des wissenschaftlichen ebenso wie des fiktionalen Diskurses. Philosophy has been called the science of the possible by philosophers as diverse as Christian Wolff and Bertrand Russell. The modal concepts of possibility and necessity, however, have proved to be ambiguous and recalcitrant to analysis, and their relation to the concept of reality have remained problematic up to the present day. Transcending the worn-out dichotomy between analytic and continental philosophy, this collection of papers takes a fresh look at the metaphysics and logic of possibility and reality, and illuminates them from a great variety of perspectives. Topics include the history of philosophy (from Greek antiquity to David Lewis) as well as the semantics of possible worlds; logic, mathematics and computer science as well as literature and the new media; forms of scientific as well as fictional discourse."

Necessary Beings is concerned with two central areas of metaphysics: modality-the theory of necessity, possibility, and other related notions; and ontology-the general study of what kinds of entities there are. Bob Hale's overarching purpose is to develop and defend two quite general theses about what is required for the existence of entities of various kinds: that questions about what kinds of things there are cannot be properly understood or adequately answered without recourse to considerations about possibility and necessity, and that, conversely, questions about the nature and basis of necessity and possibility cannot be satisfactorily tackled without drawing on what might be called the methodology of ontology. Taken together, these two theses claim that ontology and modality are mutually dependent upon one another, neither more fundamental than the other. Hale defends a broadly Fregean approach to metaphysics, according to which ontological distinctions among different kinds of things (objects, properties, and relations) are to be drawn on the basis of prior distinctions between different logical types of expression. The claim that facts about what kinds of things exist depend upon facts about what is possible makes little sense unless one accepts that at least some modal facts are fundamental, and not reducible to facts of some other, non-modal, sort. He argues that facts about what is absolutely necessary or possible have this character, and that they have their source or basis, not in meanings or concepts nor in facts about alternative 'worlds', but in the natures or essences of things.

Many systems of logic diagrams have been offered both historically and more recently. Each of them has clear limitations. An original alternative system is offered here. It is simpler, more natural, and more expressively and inferentially powerful. It can be used to analyze not only syllogisms but arguments involving relational terms and unanalyzed statement terms.

This book is about normativity and reasons. By the end, however, the subject becomes the relation between self, thought, and world. If we understand normativity, we are on the road to understanding this relation.
John Skorupski argues that all normative properties are reducible to reason relations, so that the sole normative ingredient in any normative concept is the concept of a reason. This is a concept fundamental to all thought. It is pervasive (actions, beliefs, and sentiments all fall within its range), primitive (all other normative concepts are reducible to it), and constitutive of the idea of thought itself. Thinking is sensitivity to reasons. Thought in the full sense of autonomous cognition is possible only for a being sensitive to reasons and capable of deliberating about them.
In Part II of the book Skorupski examines epistemic reasons, and shows that aprioricity, necessity, evidence, and probability, which may not seem to be normative at all, are in fact normative concepts analysable in terms of the concept of a reason. In Part III he shows the same for the concept of a person's good, and for moral concepts including the concept of a right. Part IV moves to the epistemology and metaphysics of reasons. When we make claims about reasons to believe, reasons to feel, or reasons to act we are asserting genuine propositions: judgeable, truth-apt contents. But these normative propositions must be distinguished from factual propositions, for they do not represent states of affairs.
So Skorupski's ambitious theory of normativity has broad and deep implications for philosophy. It shows how reflection on the logic, epistemology, and ontology of reasons finally leads us to an account of the interplay of self, thought, and world.

Frank Arntzenius presents a series of radical new ideas about the structure of space and time. Space, Time, and Stuff is an attempt to show that physics is geometry: that the fundamental structure of the physical world is purely geometrical structure. Along the way, he examines some non-standard views about the structure of spacetime and its inhabitants, including the idea that space and time are pointless, the idea that quantum mechanics is a completely local theory, the idea that antiparticles are just particles travelling back in time, and the idea that time has no structure whatsoever. The main thrust of the book, however, is that there are good reasons to believe that spaces other than spacetime exist, and that it is the existence of these additional spaces that allows one to reduce all of physics to geometry. Philosophy, and metaphysics in particular, plays an important role here: the assumption that the fundamental laws of physics are simple in terms of the fundamental physical properties and relations is pivotal. Without this assumption one gets nowhere. That is to say, when trying to extract the fundamental structure of the world from theories of physics one ignores philosophy at one's peril!

This book brings together papers from a conference that took place in the city of L'Aquila, 4-6 April 2019, to commemorate the 10th anniversary of the earthquake that struck on 6 April 2009. Philosophers and scientists from diverse fields of research debated the problem that, on 6 April 1922, divided Einstein and Bergson: the nature of time. For Einstein, scientific time is the only time that matters and the only time we can rely on. Bergson, however, believes that scientific time is derived by abstraction, even in the sense of extraction, from a more fundamental time. The plurality of times envisaged by the theory of Relativity does not, for him, contradict the philosophical intuition of the existence of a single time. But how do things stand today? What can we say about the relationship between the quantitative and qualitative dimensions of time in the light of contemporary science? What do quantum mechanics, biology and neuroscience teach us about the nature of time? The essays collected here take up the question that pitted Einstein against Bergson, science against philosophy, in an attempt to reverse the outcome of their monologue in two voices, with a multilogue in several voices.

This volume brings together a number of original articles by leading Leibniz scholars to address the meaning and significance of Leibniz's notions of compossibility and possible worlds. In order to avoid the conclusion that everything that exists is necessary, or that all possibles are actual, as Spinoza held, Leibniz argued that not all possible substances are compossible, that is, capable of coexisting. In Leibniz's view, the compossibility relation divides all possible substances into disjoint sets, each of which constitutes a possible world, or a way that God might have created things. For Leibniz, then, it is the compossibility relation that individuates possible worlds; and possible worlds form the objects of God's choice, from among which he chooses the best for creation. Thus the notions of compossibility and possible worlds are of major significance for Leibniz's metaphysics, his theodicy, and, ultimately, for his ethics. Given the fact, however, that none of the approaches to understanding Leibniz's notions of compossibility and possible words suggested to date have gained universal acceptance, the goal of this book is to gather a body of new papers that explore ways of either refining previous interpretations in light of the objections that have been raised against them, or ways of framing new interpretations that will contribute to a fresh understanding of these key notions in Leibniz's thought.
