Lloyd Gerson offers an original new study of Plato's account of persons, a topic of continuing interest to philosophers. His book locates Plato's psychology within his two-world metaphysics, showing that embodied persons are images of a disembodied ideal, and that they reflect many of the conflicting states of the sensible world. For Plato, Gerson argues, philosophy is the means to recognizing one's true identity.

Metaphysics has often held that laws of nature, if legitimate, must be time-independent. Yet mounting evidence from the foundations of science suggests that this constraint may be obsolete. This book provides arguments against this atemporality conjecture, which it locates both in metaphysics and in the philosophy of science, drawing on developments in a range of fields, from the foundations of physics to the philosophy of finance. It then seeks to excavate an alternative philosophical lineage which reconciles time-dependent laws with determinism, converging in the thought of Immanuel Kant.

Aristotle on Method and Metaphysics is a collection of new and cutting-edge essays by prominent Aristotle scholars and Aristotelian philosophers on themes in ontology, causation, modality, essentialism, the metaphysics of life, natural theology, and scientific and philosophical methodology. Though grounded in careful exegesis of Aristotle's writings, the volume aims to demonstrate the continuing relevance of Aristotelian ideas to contemporary philosophical debate. The contributors are Robert Bolton, Stephen Boulter, David Charles, Edward Feser, Lloyd Gerson, Gyula Klima, Kathrin Koslicki, E. J. Lowe, Fred D. Miller, Jr., David S. Oderberg, Christopher Shields, Allan Silverman, Tuomas Tahko, and Stephen Williams

This is the only commentary on Aristotle's theological work, Metaphysics, Book 12, to survive from the first six centuries CE - the heyday of ancient Greek commentary on Aristotle. Though the Greek text itself is lost, a full English translation is presented here for the first time, based on Arabic versions of the Greek and a Hebrew version of the Arabic. In his commentary Themistius offers an extensive re-working of Aristotle, confirming that the first principle of the universe is indeed Aristotle's God as intellect, not the intelligibles thought by God. The identity of intellect with intelligibles had been omitted by Aristotle in Metaphysics 12, but is suggested in his Physics 3.3 and On the Soul 3, and later by Plotinus. Laid out here in an accessible translation and accompanied by extensive commentary notes, introduction and indexes, the work will be of interest for students and scholars of Neoplatonist philosophy, ancient metaphysics, and textual transmission.

An investigation into Aristotle's metaphysics of nature as expounded in the Physics. It focuses in particular his conception of change, a concept which is shown to possess a unique metaphysical structure, with implications that should engage the attention of contemporary analysis. First published in hardback in 1982, the book is now available for the first time in paperback. 'A powerful and appealing explanatory scheme which succeeds on the whole in drawing together a great many seemingly disparate elements in the Physics into a neat unitary stucture.' Canadian Philosophical Review

In this brief and accessible introduction, Russell guides the reader through his famous 1910 distinction between "knowledge by acquaintance and knowledge by description" and introduces important theories of Plato, Aristotle, Descartes, Hume, Locke, Kant, Hegel and others. He lays the foundation for philosophical inquiry for general readers and scholars.There are sixteen chapters: Appearance and Reality, The Existence of Matter, The Nature of Matter, Idealism, Knowledge by Acquaintance and Knowledge by Description, On Induction, On Our Knowledge Of General Principles, How A Priori Knowledge Is Possible, The World of Universals, On Our Knowledge of Universals, On Intuitive Knowledge, Truth and Falsehood, Knowledge, Error, and Probable Opinion, The Limits of Philosophical Knowledge, The Value of Philosophy. Russell also provides a short supplementary reading list.

This volume explores the inadequacies of the two standard conceptions of space or spacetime, substantivalism and relationism, and in the process, proposes a new historical interpretation of these physical theories. This book also examines and develops alternative ontological conceptions of space, and explores additional historical elements of seventeenth century theories and other metaphysical themes. The author first discusses the two main opposing theories of the ontology of space. One, known as substantivalism, proposes space to be an entity that can exist independently of material things. The other, relationism, contends that space is a relation among material things. Readers will learn about specific problems with this dichotomy. First, Newton and Leibniz are often upheld as the retrospective forerunners of substantivalism and relationism. But, their work often contradicts the central tenets of these views. Second, these theories have proven problematic when transferred to a modern setting, especially with regards to general relativity and the recent quantum gravity hypotheses. The author details an alternative set of concepts that address these problems. The author also develops a new classificational system that provides a more accurate taxonomy for the elements of all spatial ontologies. This classification obtains successful analogies between Newton, Leibniz, and other natural philosophers with contemporary physical theories.

The fullest account ever written of the fascinating nexus between Islam and Time, this is a major contribution to the wider history of ideas and religion. Night and day, and the twelve lunar months of the year, are'appointed times for the believing people'. Reading the sky for the prayers of the hour has thus for Muslims been a constant reminder of God's providence and power. In her absorbing and illuminating new book, the late Barbara Freyer Stowasser examines the various ways in which Islam has structured, ordered and measured Time. Drawing on examples from Judaism and Christianity, as well as the ancient world, the author shows that while systems of time facilitate the orderly function of vastly different civilizations, in Islam they have always been fundamental. Among other topics, she discusses the Muslim lunar calendar; the rise of the science of astronomy; the remarkable career of al-Biruni, greatest authority in Muslim perceptions of Time; and the impact of technologies like the astrolabe, Indian numerals and paper. The fullest account ever written of the fascinating nexus between Islam and Time, this is a major contribution to the wider history of ideas and religion.

Dynamic Thought or the Law of Vibrant Energy, written in 1906 by W.W. Atkinson, takes relatively modern science alongside ancient occult teachings to discuss subjects often presented in Atkinson's magazine New Thought, and in many of the other books Atkinson authored. Dynamic Thought presents the ideas of a higher level of thinking and functioning, separate planes of the mind, and how forces in nature and the law of attraction can affect our actions, or the way others act toward us. Like much of his work, this book is designed for the student of psychological and philosophical thought. American writer WILLIAM WALKER ATKINSON (1862-1932) was editor of the popular magazine New Thought from 1901 to 1905, and editor of the journal Advanced Thought from 1916 to 1919. He authored dozens of New Thought books under numerous pseudonyms, including "Yogi," some of which are likely still unknown today.

The old philosophical discipline of metaphysics - after having been pronounced dead by many - has enjoyed a significant revival within the last thirty years, due to the application of the methods of analytic philosophy. One of the major contributors to this revival is the outstanding American metaphysician Peter van Inwagen. This volume brings together twenty-two scholars, who, in commemoration of Prof. van Inwagen's 75th birthday, ponder the future prospects of metaphysics in all the richness to which it has now returned. It is only natural that logical and epistemological reflections on the significance of metaphysics - sometimes called "meta-metaphysics" - play a considerable role in most of these papers. The volume is further enriched by an interview with Peter van Inwagen himself.

Hud Hudson offers a fascinating examination of philosophical reasons to believe in hyperspace. He begins with some stage-setting discussions, offering his analysis of the term 'material object', noting his adherence to substantivalism, confessing his sympathies regarding principles of composition and decomposition, identifying his views on material simples, material gunk, and the persistence of material objects, and preparing the reader for later discussions with introductory remarks on eternalism, modality and recombination, vagueness, bruteness, and the epistemic role of intuitions. The subsequent chapters are loosely organized around the theme of hyperspace. Hudson explores nontheistic reasons to believe in hyperspace in chapter 1 (e.g. reasons arising from reflection on incongruent counterparts and fine-tuning arguments), theistic reasons in chapter 7 (e.g. reasons arising from reflection on theistic puzzles known as the problem of the best and the problem of evil), and some distinctively Christian reasons in chapter 8 (e.g. reasons arising from reflection on traditional Christian themes such as heaven and hell, the Garden of Eden, angels and demons, and new testament miracles). In the intervening chapters, Hudson inquires into a variety of puzzles in the metaphysics of material objects that are either generated by the hypothesis of hyperspace, focusing on the topics of mirror determinism and mirror incompatibilism, or else informed by the hypothesis of hyperspace, with discussions of receptacles, boundaries, contact, occupation, and superluminal motion. Anyone engaged with contemporary metaphysics will find much to stimulate them here.

The Multiple States of the Being is the companion to, and the completion of, The Symbolism of the Cross, which, together with Man and His Becoming according to the Vedanta, constitute Reni Guinon's great trilogy of pure metaphysics. In this work, Guinon offers a masterful explication of the metaphysical order and its multiple manifestations-of the divine hierarchies and what has been called the Great Chain of Being-and in so doing demonstrates how jqana, intellective or intrinsic knowledge of what is, and of That which is Beyond what is, is a Way of Liberation. Guinon the metaphysical social critic, master of arcane symbolism, comparative religionist, researcher of ancient mysteries and secret histories, summoner to spiritual renewal, herald of the end days, disappears here. Reality remains.

There are few more unsettling philosophical questions than this: What happens in attempts to reduce some properties to some other more fundamental properties? Reflection on this question inevitably touches on very deep issues about ourselves, our own interactions with the world and each other, and our very understanding of what there is and what goes on around us. If we cannot command a clear view of these deep issues, then very many other debates in contemporary philosophy seem to lose traction - think of causation, laws of nature, explanation, consciousness, personal identity, intentionality, normativity, freedom, responsibility, justice, and so on. Reduction can easily seem to unravel our world.
Here, an eminent group of philosophers helps us answer this question. Their novel contributions comfortably span a number of current debates in philosophy and cognitive science: what is the nature of reduction, of reductive explanation, of mental causation? The contributions range from approaches in theoretical metaphysics, over philosophy of the special sciences and physics, to interdisciplinary studies in psychiatry and neurobiology. The authors connect strands in contemporary philosophy that are often treated separately and in combination the chapters allow the reader to see how issues of reduction, explanation and causation mutually constrain each other. The anthology therefore moves the debate further both at the level of contributions to specific debates and at the level of integrating insights from a number of debates.

what makes a property intrinsic? What exactly does the intrinsic/extrinsic distinction rest upon, and how can we reasonably justify this distinction? These questions bear great importance on central debates in such diverse philosophical fields as ethics (What is the nature of intrinsic value?), philosophy of mind (Does mental content supervene on internal bodily features?), epistemology (Can intrinsic duplicates differ in the justification of their beliefs?) and philosophy of science (Do the causal powers of an object depend on its extrinsic features?) - to only name a few. Given the central relevance of the intrinsic/extrinsic distinction to philosophical research, a collection of pertinent essays on the topic is an essential addition to the literature. It helps to identify more clearly the problems and arguments that are at stake. The anthology provides a comprehensive overview of central facets of the debates, including both crucial earlier and important new contributions by leading philosophers. As such it constitutes an indispensable component of any serious study of the topic.

This book explores the thought of Alexius Meinong, a philosopher known for his unconventional theory of reference and predication. The chapters cover a natural progression of topics, beginning with the origins of Gegenstandstheorie, Meinong's theory of objects, and his discovery of assumptions as a fourth category of mental states to supplement his teacher Franz Brentano's references to presentations, feelings, and judgments. The chapters explore further the meaning and metaphysics of fictional and other nonexistent intended objects, fine points in Meinongian object theory are considered and new and previously unanticipated problems are addressed. The author traces being and non-being and aspects of beingless objects including objects in fiction, ideal objects in scientific theory, objects ostensibly referred to in false science and false history and intentional imaginative projection of future states of affairs. The chapters focus on an essential choice of conceptual, logical, semantic, ontic and more generally metaphysical problems and an argument is progressively developed from the first to the final chapter, as key ideas are introduced and refined. Meinong studies have come a long way from Bertrand Russell's off-target criticisms and recent times have seen a rise of interest in a Meinongian approach to logic and the theory of meaning. New thinkers see Meinong as a bridge figure between analytic and continental thought, thanks to the need for an adequate semantics of meaning in philosophy of language and philosophy of mind, making this book a particularly timely publication.

Truth Through Proof defends an anti-platonist philosophy of mathematics derived from game formalism. Classic formalists claimed implausibly that mathematical utterances are truth-valueless moves in a game. Alan Weir aims to develop a more satisfactory successor to game formalism utilising a widely accepted, broadly neo-Fregean framework, in which the proposition expressed by an utterance is a function of both sense and background circumstance. This framework allows for sentences whose truth-conditions are not representational, which are made true or false by conditions residing in the circumstances of utterances but not transparently in the sense.
Applications to projectivism and fiction pave the way for the claim that mathematical utterances are made true or false by the existence of concrete proofs or refutations, though these truth-making conditions form no part of their sense or informational content.
The position is compared with rivals, an account of the applicability of mathematics developed, and a new account of the nature of idealisation proffered in which it is argued that the finitistic limitations Godel placed on proofs are without rational justification. Finally a non-classical logical system is provided in which excluded middle fails, yet enough logical power remains to recapture the results of standard mathematics.

The nine original essays collected in this volume explore the themes of philosophical progress, ultimate explanation, the metaphysics of free will, and the relation of sciences and religion. These essays exemplify Nicholas Rescher's characteristic mode of combining historical perspectives with analytical elucidation on philosophically contested issues and utilize this methodology to address some of the salient problems of the field.

Over recent decades, Spinoza scholarship has significantly developed in both France and the United States, shedding new light on the work of this major philosopher. Spinoza in Twenty-First-Century American and French Philosophy systematically unites for the first time American and French Spinoza specialists in conversation with each other, illustrating the fecundity of bringing together diverse approaches to the study of Early Modern philosophy. Spinoza in Twenty-First-Century American and French Philosophy gives readers a unique opportunity to discover the most consequential and sophisticated aspects of American and French Spinoza research today. Featuring chapters by American scholars with French experts responding to these, the book is structured according to the themes of Spinoza's philosophy, including metaphysics, philosophy of mind, moral philosophy and political philosophy. The contributions consider the full range of Spinoza's philosophy, with chapters addressing not only the Ethics but his lesser-known early works and political works as well. Issues covered include Spinoza's views on substance and mode, his conception of number, his account of generosity as freedom, and many other topics.
