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 the logics. 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 analysis of 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.

A team of leading experts investigate a range of philosophical issues to do with the self and self-knowledge. Self and Self-Knowledge focuses on two main problems: how to account for I-thoughts and the consequences that doing so would have for our notion of the self; and how to explain subjects' ability to know the kind of psychological states they enjoy, which characteristically issues in psychological self-ascriptions. The first section of the volume consists of essays that, by appealing to different considerations which range from the normative to the phenomenological, offer an assessment of the animalist conception of the self. The second section presents an examination as well as a defence of the new epistemic paradigm, largely associated with recent work by Christopher Peacocke, according to which knowledge of our own mental states and actions should be based on an awareness of them and of our attempts to bring them about. The last section explores a range of different perspectives-from neo-expressivism to constitutivism-in order to assess the view that self-knowledge is more robust than any other form of knowledge. While the contributors differ in their specific philosophical positions, they all share the view that careful philosophical analysis is needed before scientific research can be fruitfully brought to bear on the issues at hand. These thought-provoking essays provide such an analysis and greatly deepen our understanding of these central aspects of our mentality.

The correspondence between Leibniz and Samuel Clarke was the most influential philosophical exchange of the eighteenth century, and indeed one of the most significant such exchanges in the history of philosophy. Carried out in 1715 and 1716, the debate focused on the clash between Newtonian and Leibnizian world systems, involving disputes in physics, theology, and metaphysics. The letters ranged over an extraordinary array of topics, including divine immensity and eternity, the relation of God to the world, free will, gravitation, the existence of atoms and the void, and the size of the universe.
This penetrating book is the first to offer a comprehensive overview and commentary on the Leibniz-Clarke correspondence. Building his narrative around general subjects covered in the exchange--God, the soul, space and time, miracles and nature, matter and force--Ezio Vailati devotes special attention to a question crucial for Leibniz and Clarke alike. Both philosophers, worried by the advance of naturalism and its consequences for morality, devised complex systems to counter naturalism and reinforce natural religion. However, they not only deeply disagreed on how to answer the naturalist threat, but they ended up seeing in each other's views the germs of naturalism itself. Vailati rigorously tracks the twists and turns of this argument, shedding important new light on a critical moment in modern philosophy.
Lucid, taut, and energetically written, this book not only examines the Leibniz-Clarke debate in unprecedented depth but also situates the views advanced by the two men in the context of their principal writings. An invaluable reference to a fascinating exchange of ideas, Leibnizand Clarke makes vital reading for philosophers and historians of science and theology.

Randolph Clarke examines free will in the context of determinism on the one hand, and the notion that this choice may in fact be random and arbitrary on the other. In the first half of the book, he provides a careful, 'conceptual' assessment of the various libertarian theories that do not appeal to agent causation, and contends that they fail to provide an adequate account of the control required by free will. The second half is a development of his own theory of causation, where he suggests that a satisfactory account of this type of control is possible and necessary, constituting a significant advance in our understanding of free will and the moral responsibility that follows from it.

The capacity to represent things to ourselves as possible plays a crucial role both in everyday thinking and in philosophical reasoning; this volume offers much-needed philosophical illumination of conceivability, possibility, and the relations between them.

Collected in this 3-in-one omnibus edition are Kant's ground breaking critiques. The Critique of Pure Reason, The Critique of Practical Reason, and The Critique of Judgement. The Critique of Pure Reason is one of the most influential philosophy books of all times. Kant's influence on modern perception of reason cannot be over estimated. Here Kant redefines reason and gives us the tools to understand reason on two levels: the empirical and the metaphysical. The Critique of Practical Reason is the second of Immanuel Kant's three critiques and it deals with Kant's own moral philosophy and his views on free will. A masterpiece of philosophical writing. In The Critique of Judgement Kant states that "Philosophy may be said to contain the principles of the rational cognition that concepts afford us of things (not merely, as with logic, the principles of the form of thought in general irrespective of the objects), and, thus interpreted, the course, usually adopted, of dividing it into theoretical and practical is perfectly sound."

- Your true essence survives the physical death of your body - Your soul is the true essence of who you are; not your body - In all likelihood, you have lived before in a much different body - All souls originated from the same God-sourced energy - As humans living on Earth, we are "ONE" big, soul family This book combines science and spirituality in a unique way. It contains carefully documented descriptions by a trained research scientist of visions, which I received as a result of prayers and requests for information. Science of Prayer validates the usefulness of walking a path of spiritual wholeness. The author describes his search for answers to help explain his experiences. This journey takes us through the study of consciousness, psychic development classes, training in an energy healing modality, and much more. It describes what the author did, and suggests exercises to help put you in the best possible position to receive the guidance that you are given. Richard Rominger "This remarkable story gives us all a glimpse into what is possible when you allow your six sensory abilities to open up to Spirit." --Sonia Choquette, New York Times bestselling author

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.

This writing will be an examination of Muhammad and the Koran as the foundational sources of Muhammadism and whether their commands are compatible with the 21st Century. We will be comparing modern day spiritual/scientific eclecticism using most religions, sciences, common knowledge and reason with Muhammaden source materials and practice while seeking a bridge from archaic practice and barbarism to acceptable modern day morality.

Comparing the lived world with the ideal world, noted American philosophical naturalist, poet, and literary critic George Santayana (1863-1952) seeks in this influential compilation of his earlier works to outline the ancient ideal of a well-ordered life, one in which reason is the organizing force that recognizes the need to allocate science, religion, art, social concerns, and practical wisdom their proper role and appropriate emphasis within the fully developed human experience.

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".
