I have little to say on this passage, where it seems necessary to maintain the vulgate notwith standing its obvious defects. My only reason for discussing it is to call attention to the strangeness of Jebb's proceeding when seeking to support Hermann's conjecture παλλλοιν which he admits into the text. The objection to Hermann's view is that, as he himself admits, there is no evidence that πáλληλος could be used in the sense of λληλιφóνος. For that, I suppose, is the (...) meaning of ‘mutual hands,’ which both Jebb and Campbell suggest as a translation, although ‘mutual violence’ would be better. But the chief purpose of this note is to protest against the mode of interpretation applied to Philo de Mose 3. 36. II. p. 175 M. διà τàς ν δασι καí πνρì γνιμéνας συνχς καì παλλλονς φθορáς Turnebu s rightl yrenders ‘alternas interneciones,’ and why Jebb supposes him to have meant ‘mutual’ I do not know. Anyhow he admits that Philo used the word in its ordinary sense of successive, and proceeds to paraphrase ‘owing to the continuous and rapid succession of calamities by flood and fire’ . All this is quite beside the mark, for the reference is to the alternate destruction of the world at the κπρωσις by fire and at the ξγρωσιςby water. I must take leave to refer to the evidence collected in my book on Zeno and Cleanthes, p. 253, to which should be added a most instructive passage of Origen : περì τν κακν λóγος ο μνóντων ì ν τατᾦ διà τν τοι τηροσαν τà πì γ$$$ς πρóνοιαν κατακλνσμο καì κπνρ03CE;σσι καθαíρονσαν.Add the passages from Lucan quoted by Mr. Heitland in his Introduction, p. xliii.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Ludwig Wittgenstein (1889-1951) was an extraordinarily original thinker, whose influence on twentieth-century thinking far outside the bounds of philosophy alone. In this engaging Introduction, A.C. Grayling makes Wittgenstein's thought accessible to the general reader by explaining the nature and impact of Wittgenstein's views. He describes both his early and later philosophy, the differences and connections between them, and gives a fresh assessment of Wittgenstein's continuing influence on contemporary thought.

The so-called quantum Zeno effect is essentially a consequence of the projection postulate for ideal measurements. To test the effect, Itanoet al. have performed an experiment on an ensemble of atoms where rapidly repeated level measurements were realized by means of short laser pulses. Using dynamical considerations, we give an explanation why the projection postulate can be applied in good approximation to such measurements. Corrections to ideal measurements are determined explicitly. This is used to discuss how far the experiment of (...) Itanoet al. can be considered as a test of the quantum Zeno effect. We also analyze a new possible experiment on a single atom where stochastic light and dark periods can be interpreted as manifestation of the quantum Zeno effect. We show that the measurement point of view gives a quick and intuitive understanding of experiments of the above type, although a finer analysis has to take the corrections into account. (shrink)

There are good reasons to think there is a universal, fundamental length, specifically, at the order of the Planck length. If this holds, we then have an empirical answer for Zeno’s paradox of Achilles and the tortoise, a potential impasse in the second premise of the kalam cosmological argument, and creation ex nihilo. In this paper, I establish metaphysical, empirical, and epistemic reasons suggesting there is a universal, fundamental length. Along the way, I propose a “contingent necessity” for such a (...) notion. I then detail how a universal, fundamental length is a preferred solution for issues –. (shrink)

The propagation of causal influences through space-time seems to play a fundamental role in scientific explanation. Taking as a point of departure a basic distinction between causal interactions (which are localized in space-time) and causal processes (which may extend through vast regions of space-time), this paper attempts an analysis of the concept of causal propagation on the basis of the ability of causal processes to transmit "marks." The analysis rests upon the "at-at" theory of motion which has figured prominently in (...) the resolution of Zeno's arrow paradox. It is argued that this explication does justice to the concept of the ability of causal processes to transmit causal influence without invoking anti-Humean "powers" or "necessary connections.".

This comprehensive new collection is designed as a complete introduction to philosophy for students and general readers. Consisting of eleven extended essays, specially commissioned for this volume from leading philosophers, the book surveys all of the major areas of philosophy and offers an accessible but sophisticated guide to the main debates. An extended introduction provides general context and explains how the different subjects are related. The first part of the book deals with the foundations of philosophical inquiry: epistemology, philosophical logic, (...) methodology, metaphysics, and the philosophy of mind. The second part offers historical chapters, two on ancient philosophy and two on modern philosophy. Finally, two chapters deal with questions of value, ethics and aesthetics. Each chapter has a full bibliography. The contributors include Bernard Williams, Roger Scruton, Martin Davies, David Wiggins, Christopher Janaway, David Papineau, and Mark Sainsbury. Designed to be as useful to the third-year student as to the beginner, this exciting new text will give each reader a unique sense of involvement in philosophy as it is practiced today. (shrink)

Bertrand Russell (1872-1970) is one of the most famous and important philosophers of the twentieth century. In this account of his life and work A.C. Grayling introduces both his technical contributions to logic and philosophy, and his wide-ranging views on education, politics, war, andsexual morality. Russell is credited with being one of the prime movers of Analytic Philosophy, and with having played a part in the revolution in social attitudes witnessed throughout the twentieth-century world. This introduction gives a clear survey (...) of Russell's achievements across their wholerange. (shrink)

The 1981 Dahlem conference was a catalyst for contemporary evolutionary developmental biology (Evo-devo). This introductory chapter rehearses some of the details of the history surrounding the original conference and its associated edited volume, explicates the philosophical problem of conceptual change that provided the rationale for a workshop devoted to evaluating the epistemic revisions and transformations that occurred in the interim, explores conceptual change with respect to the concept of evolutionary novelty, and highlights some of the themes and patterns in the (...) different contributions to the present volume, Conceptual Change in Biology: Scientific and Philosophical Perspectives on Evolution and Development.

'The unconsidered life is not worth living' - Socrates. Thinking about life, what it means and what it holds in store does not have to be a despondent experience, but rather can be enlightening and uplifting. A life truly worth living is one that is informed and considered so a degree of philosophical insight into the inevitabilities of the human condition is inherently important and such an approach will help us to deal with real personal dilemmas. This book is an (...) accessible, lively and thought-provoking series of linked commentaries, based on A. C. Grayling's 'The Last Word' column in the Guardian. Its aim is not to persuade readers to accept one particular philosophical point of view or theory, but to help us consider the wonderful range of insights which can be drawn from an immeasurably rich history of philosophical thought. Concepts covered include courage, love, betrayal, ambition, cruelty, wisdom, passion, beauty and death. This will be a wonderfully stimulating read and act as an invaluable guide as to what is truly important in living life, whether facing success, failure, justice, wrong, love, loss or any of the other profound experience life throws out.

In this benchmark five-volume study, originally published between 1922 and 1955, Surendranath Dasgupta examines the principal schools of thought that define Indian philosophy. A unifying force greater than art, literature, religion, or science, Professor Dasgupta describes philosophy as the most important achievement of Indian thought, arguing that an understanding of its history is necessary to appreciate the significance and potentialities of India's complex culture. Volume I offers an examination of the Vedas and the Brahmanas, the earlier Upanisads, and the six (...) systems of Indian philosophy. (shrink)

"A distinctive voice somewhere between Mark Twain and Michel Montaigne" is how Psychology Today described A.C. Grayling. In Life, Sex, and Ideas: The Good Life Without God, readers have the pleasure of hearing this distinctive voice address some of the most serious topics in philosophy--and in our daily lives--including reflections on guns, anger, conflict, war; monsters, madness, decay; liberty, justice, utopia; suicide, loss, and remembrance. A civilized society, says Grayling, is one which never ceases having a discussion with itself about (...) what human life should best be. In this book, Grayling adds to this discussion a series of short informal essays about ethics, ideas, and culture. A recurring theme is religion, of which he writes "there is no greater social evil." He argues, for instance, that liberal education is better than religion for inculcating moral values. "Education in literature, history, and appreciation of the arts," he says, "opens the possibility for us to live more reflectively and knowledgeably, especially about the nature and variety of human experience. That in turn increases our capacity for understanding others better, so that we can treat them with respect and sympathy, however different their outlook on life." Thought provoking rather than definitive, these essays don't tell readers what to think, but only note what has been thought about how it is best to live. A person who does not think about life, the author reminds us, is like a stranger mapless in a foreign land. These brief and suggestive essays offer us the outlines of a map, with avenues of thought that are a pleasure to wander down. (shrink)

A traditional approach to teaching medical ethics aims to provide knowledge about ethics. This is in line with an epistemological view on ethics in which moral expertise is assumed to be located in theoretical knowledge and not in the moral experience of healthcare professionals. The aim of this paper is to present an alternative, contextual approach to teaching ethics, which is grounded in a pragmatic-hermeneutical and dialogical ethics. This approach is called moral case deliberation. Within moral case deliberation, healthcare professionals (...) bring in their actual moral questions during a structured dialogue. The ethicist facilitates the learning process by using various conversation methods in order to find answers to the case and to develop moral competencies. The case deliberations are not unique events, but are a structural part of the professional training on the work floor within healthcare institutions. This article presents the underlying theory on ethics and illustrates this approach with an example of a moral case deliberation project in a Dutch psychiatric hospital. The project was evaluated using the method of responsive evaluation. This method provided us with rich information about the implementation process and effects the research process itself also lent support to the process of implementation. (shrink)

In mathematics, the deductive method reigns. Without proof, a claim remains unsolved, a mere conjecture, not something that can be simply assumed; when a proof is found, the problem is solved, it turns into a “result,” something that can be relied on. So mathematicians think. But is there more to mathematical justification than proof?The answer is an emphatic yes, as I explain in this chapter. I argue that non-deductive justification is in fact pervasive in mathematics, and that it is in (...) good epistemic standing. (shrink)

This paper investigates the view that digital hypercomputing is a good reason for rejection or re-interpretation of the Church-Turing thesis. After suggestion that such re-interpretation is historically problematic and often involves attack on a straw man (the ‘maximality thesis’), it discusses proposals for digital hypercomputing with Zeno-machines , i.e. computing machines that compute an infinite number of computing steps in finite time, thus performing supertasks. It argues that effective computing with Zeno-machines falls into a dilemma: either they are specified such (...) that they do not have output states, or they are specified such that they do have output states, but involve contradiction. Repairs though non-effective methods or special rules for semi-decidable problems are sought, but not found. The paper concludes that hypercomputing supertasks are impossible in the actual world and thus no reason for rejection of the Church-Turing thesis in its traditional interpretation. (shrink)

This reflective work wants to disclose the intention moving early Greek philosophy, which, as the title hints, sought to lay bare the ground for "the way things are." The failure of the physiologoi to discover in nature an intelligible Gegenwart in which nature as a whole could appear led Heraclitus and Parmenides, to whom most of the book is devoted, to examine the ground of logos, and therewith, of truth and opinion. Commensurate with his intention to emphasize those elements of (...) early Greek philosophy common to its greatest representatives, Boeder concludes by pursuing his theme into Zeno's development of dialectic.--H. C. (shrink)

Discussions range from the paradoxes of Zeno to Heidegger's conception of truth, with greatest emphasis on Hegel. The questioning is always meticulous without being pedantic. Whether dealing with an individual thinker or a problem in the history of ideas, Koyre enters into a dialogue which brings his subject to life in a compelling way.--W. H. C.

Philosopher Roger Scruton offers a wide-ranging perspective on philosophy, from logic to aesthetics, written in a lively and engaging way that is sure to stimulate debate. Rather than producing a survey of an academic discipline, Scruton reclaims philosophy for worldly concerns.

Several interesting themes emerge from G. E. Moore’s previously unpub­lished review of _The Principles of Mathematics_. These include a worry concerning whether mathematical notions are identical to purely logical ones, even if coextensive logical ones exist. Another involves a conception of infinity based on endless series neglected in the Principles but arguably involved in Zeno’s paradox of Achilles and the Tortoise. Moore also questions the scope of Russell’s notion of material implication, and other aspects of Russell’s claim that mathematics reduces (...) to logic. (shrink)

This a general account of the school of Mo-tzu, its social basis as a movement of craftsmen, its isolated place in the Chinese tradition, and the nature of its later contributions to logic, ethics, and science. It assesses the relation of Mohist thinking to the structure of the Chinese language, and grapples with the textual dynamics of later Mohist writings, particularly in regard to grammar and style, technical terminology, the use and significance of stock examples, and overall organization. Includes edited (...) and annotated Chinese text with an English translation and commentary, a glossary, and a photographic reproduction of the unemended text from the Taoist Patrology. (shrink)

Cutting across boundaries of art and science, evolution is a fundamental process that has beguiled thinkers through the ages. This collection draws together world renowned thinkers and communicators with their own intriguing insights. In these essays they offer a feast of dazzling thoughts and ideas to challenge and enthrall the reader. Why and how do civilisations and societies change over time? Why do our cells develop the way they do? Why are some villages still villages while others have grown into (...) vast cities? Can we learn from our evolutionary past to plan a better future for our health and society? Tracing a line from the history of biological evolution, through the evolution of cultures, society, science and the universe, Evolution brings together intriguing parallels from all levels of life. From the evolution of the developing embryo to the evolution of a developing star, common threads develop into a fascinating story. (shrink)

A Gedanken experiment is presented where an excited and a ground-state atom are positioned such that, within the former’s half-life time, they exchange a photon with 50% probability. A measurement of their energy state will therefore indicate in 50% of the cases that no photon was exchanged. Yet other measurements would reveal that, by the mere possibility of exchange, the two atoms have become entangled. Consequently, the “no exchange” result, apparently precluding entanglement, is non-locally established between the atoms by this (...) very entanglement. This quantum-mechanical version of the ancient Liar Paradox can be realized with already existing transmission schemes, with the addition of Bell’s theorem applied to the no-exchange cases. Under appropriate probabilities, the initially-excited atom, still excited, can be entangled with additional atoms time and again, or alternatively, exert multipartite nonlocal correlations in an interaction free manner. When densely repeated several times, this result also gives rise to the Quantum Zeno effect, again exerted between distant atoms without photon exchange. We discuss these experiments as variants of interaction-free-measurement, now generalized for both spatial and temporal uncertainties. We next employ weak measurements for elucidating the paradox. Interpretational issues are discussed in the conclusion, and a resolution is offered within the Two-State Vector Formalism and its new Heisenberg framework. (shrink)

In the light of increasing public mistrust, there is an urgent need to clarify the moral status of the medical profession and of the relationship of the clinician to his/her patients. In addressing this question, I first establish the coherence, within moral philosophy generally, of the concept of supererogation . I adopt the notion of an act of “unqualified” supererogation as one that is non-derivatively good, praiseworthy, and freely undertaken for others' benefit at the risk of some cost to the (...) agent. I then argue that committing oneself to the profession of clinical medicine is an act of this kind. This is the case, not because the aim of medicine is to help patients, but because of the open ended commitment of time and the vulnerability to the consequences of failure that the clinician must accept.
