Hallucination: the perception of an impossible image. That which can never appear suddenly does so anyways - a private world that appears only to the eye of the one imagining it... until now. Ted Serios, psychic photographer, claimed he could project images directly from his mind onto photographic film. Under the sign of the psychic photograph, “Hallucinating Ted Serios” is a theorization of the dominant forms of uncertainty that persist in postmodern evaluations of representation, interpretation and identity. The central thesis (...) of this paper is that the imaginary and the real have collapsed into the spectral hallucination of one another, rendering impossible the rhetorical separation of hallucination from image. With the collapse of the boundary between the fictive and the real, the world of representation becomes intelligible only as an imaginary phenomenon; with the collapse between the object and the observer, interpretation is rendered deceptively magical; and, with the collapse between the self and its anonymous double, identity itself is relegated to a state of impossibility. Consequently, under the persisting signs of the imaginary, the magical and the impossible, “Hallucinating Ted Serios” asserts that in our contemporary world there no longer exists the possibility of failed performativity – psychic, imaginary or otherwise.

This is a review of the issue of randomness in quantum mechanics, with special emphasis on its ambiguity; for example, randomness has different antipodal relationships to determinism, computability, and compressibility. Following a philosophical discussion of randomness in general, I argue that deterministic interpretations of quantum mechanics are strictly speaking incompatible with the Born rule. I also stress the role of outliers, i.e. measurement outcomes that are not 1-random. Although these occur with low probability, their very existence implies that the no-signaling (...) principle used in proofs of randomness of outcomes of quantum-mechanical measurements should be reinterpreted statistically, like the second law of thermodynamics. In three appendices I discuss the Born rule and its status in both single and repeated experiments, review the notion of 1-randomness that in various guises was investigated by Kolmogorov and others and treat Bell’s Theorem and the Free Will Theorem with their implications for randomness.

I argue that Bohmian mechanics cannot reasonably be claimed to be a deterministic theory. If one assumes the “quantum equilibrium distribution” provided by the wave function of the universe, Bohmian mechanics requires an external random oracle in order to describe the algorithmic randomness properties of typical outcome sequences of long runs of repeated identical experiments. This oracle lies beyond the scope of Bohmian mechanics, including the impossibility of explaining the randomness property in question from “random” initial conditions. Thus the advantages (...) of Bohmian mechanics over other interpretations of quantum mechanics, if any, must lie at an ontological level, and in its potential to derive the quantum equilibrium distribution and hence the Born rule.

This book studies the foundations of quantum theory through its relationship to classical physics. This idea goes back to the Copenhagen Interpretation (in the original version due to Bohr and Heisenberg), which the author relates to the mathematical formalism of operator algebras originally created by von Neumann. The book therefore includes comprehensive appendices on functional analysis and C*-algebras, as well as a briefer one on logic, category theory, and topos theory. Matters of foundational as well as mathematical interest that are (...) covered in detail include symmetry (and its "spontaneous" breaking), the measurement problem, the Kochen-Specker, Free Will, and Bell Theorems, the Kadison-Singer conjecture, quantization, indistinguishable particles, the quantum theory of large systems, and quantum logic, the latter in connection with the topos approach to quantum theory.

Einstein's philosophy of physics (as clarified by Fine, Howard, and Held) was predicated on his Trennungsprinzip, a combination of separability and locality, without which he believed objectification, and thereby "physical thought" and "physical laws", to be impossible. Bohr's philosophy (as elucidated by Hooker, Scheibe, Folse, Howard, Held, and others), on the other hand, was grounded in a seemingly different doctrine about the possibility of objective knowledge, namely the necessity of classical concepts. In fact, it follows from Raggio's Theorem in algebraic (...) quantum theory that - within an appropriate class of physical theories - suitable mathematical translations of the doctrines of Bohr and Einstein are equivalent. Thus - upon our specific formalization - quantum mechanics accommodates Einstein's Trennungsprinzip if and only if it is interpreted a la Bohr through classical physics. Unfortunately, the protagonists themselves failed to discuss their differences in this constructive way, since their debate was dominated by Einstein's ingenious but ultimately flawed attempts to establish the "incompleteness" of quantum mechanics. This aspect of their debate may still be understood and appreciated, however, as reflecting a much deeper and insurmountable disagreement between Bohr and Einstein about the knowability of Nature. Using the theological controversy on the knowability of God as a analogy, we can say that Einstein was a Spinozist, whereas Bohr could be said to be on the side of Maimonides. Thus Einstein's off-the-cuff characterization of Bohr as a 'Talmudic philosopher' was spot-on. (shrink)

Beginning with Anderson, spontaneous symmetry breaking in infinite quantum systems is often put forward as an example of emergence in physics, since in theory no finite system should display it. Even the correspondence between theory and reality is at stake here, since numerous real materials show ssb in their ground states, although they are finite. Thus against what is sometimes called ‘Earman's Principle’, a genuine physical effect seems theoretically recovered only in some idealisation, disappearing as soon as the idealisation is (...) removed.We review the well-known arguments that no finite system can exhibit ssb, using the formalism of algebraic quantum theory in order to control the thermodynamic limit and unify the description of finite- and infinite-volume systems. Using the striking mathematical analogy between the thermodynamic limit and the classical limit, we show that a similar situation obtains in quantum mechanics versus classical mechanics.This discrepancy between formalism and reality is quite similar to the measurement problem, and hence we address it in the same way, adapting an argument of the Landsman and Reuvers that was originally intended to explain the collapse of the wave-function within conventional quantum mechanics. Namely, exponential sensitivity to perturbations of the dynamics as the system size increases causes symmetry breaking already in finite but very large quantum systems. This provides continuity between finite- and infinite-volume descriptions of quantum systems featuring ssb and hence restores Earman's Principle. (shrink)

The relationship between classical and quantum theory is of central importance to the philosophy of physics, and any interpretation of quantum mechanics has to clarify it. Our discussion of this relationship is partly historical and conceptual, but mostly technical and mathematically rigorous, including over 500 references. For example, we sketch how certain intuitive ideas of the founders of quantum theory have fared in the light of current mathematical knowledge. One such idea that has certainly stood the test of time is (...) Heisenberg's `quantum-theoretical Umdeutung (reinterpretation) of classical observables', which lies at the basis of quantization theory. Similarly, Bohr's correspondence principle (in somewhat revised form) and Schroedinger's wave packets (or coherent states) continue to be of great importance in understanding classical behaviour from quantum mechanics. On the other hand, no consensus has been reached on the Copenhagen Interpretation, but in view of the parodies of it one typically finds in the literature we describe it in detail. On the assumption that quantum mechanics is universal and complete, we discuss three ways in which classical physics has so far been believed to emerge from quantum physics, namely in the limit h -> 0 of small Planck's constant (in a finite system), in the limit N goes to infinity of a large system with $N$ degrees of freedom (at fixed h), and through decoherence and consistent histories. The first limit is closely related to modern quantization theory and microlocal analysis, whereas the second involves methods of C*-algebras and the concepts of superselection sectors and macroscopic observables. In these limits, the classical world does not emerge as a sharply defined objective reality, but rather as an approximate appearance relative to certain ``classical" states and observables. Decoherence subsequently clarifies the role of such states, in that they are ``einselected", i.e. robust against coupling to the environment. Furthermore, the nature of classical observables is elucidated by the fact that they typically define (approximately) consistent sets of histories. This combination of ideas and techniques does not quite resolve the measurement problem, but it does make the point that classicality results from the elimination of certain states and observables from quantum theory. Thus the classical world is not created by observation (as Heisenberg once claimed), but rather by the lack of it. (shrink)

Here Julie Landsman chronicles one year as a teacher in a program for students in such serious trouble they are asked to leave their middle schools and attend a special program for disruptive students. She allows her readers to get to know the students, their home and street situations, and how their stories develop over the year, and in doing so, shows the complexity of young people, their beauty, and their individuality.

We attempt to clarify the main conceptual issues in approaches to ‘objectification’ or ‘measurement’ in quantum mechanics which are based on superselection rules. Such approaches venture to derive the emergence of classical ‘reality’ relative to a class of observers; those believing that the classical world exists intrinsically and absolutely are advised against reading this paper. The prototype approach (K. Hepp, Helv. Phys. Acta45 (1972), 237–248) where superselection sectors are assumed in the state space of the apparatus is shown to be (...) untenable. Instead, one should couple system and apparatus to an environment, and postulate superselection rules for the latter. These are motivated by the locality of any observer or other (actual or virtual) monitoring system. In this way ‘environmental’ solutions to the measurement problem (H.D. Zeh, Found. Phys.1 (1970), 69–76; W. H. Zurek, Phys. Rev.D26 (1982), 1862–1880 and Progr. Theor. Phys.89 (1993), 281–312) become consistent and acceptable, too. Points of contact with the modal interpretation are briefly discussed. We propose a minimal value attribution to observables in theories with superselection rules, in which only central observables have properties. In particular, the eigenvector-eigenvalue link is dropped. This is mainly motivated by Ockham's razor. (shrink)

We are often uncertain how to behave morally in complex situations. In this controversial study, Ted Lockhart contends that moral philosophy has failed to address how we make such moral decisions. Adapting decision theory to the task of decision-making under moral uncertainly, he proposes that we should not always act how we feel we ought to act, and that sometimes we should act against what we feel to be morally right. Lockhart also discusses abortion extensively and proposes new ways to (...) deal with the ethical and moral issues which surround it. (shrink)

Growing Up White is for everyone who wants to know more about our schools, our community, our country, and ourselves. Julie Landsman takes the reader on an inventory of her life, pulling from events and scenes, a set of lessons learned. She discloses honestly and unflinchingly the privileges she has experienced as a white person and connects those to her presence in city classrooms where she taught for over 25 years. As a teacher Julie made mistakes, learned from them, (...) made more and concludes that understanding race in America is an ongoing process. Her book is rich with suggestions for working in our schools today, where we find a primarily white teaching force and an expanding population of students of color. She believes that these students make our schools rich and exciting places in which to work. Landsman also believes that white teachers can reach their students in deep and positive ways. Because she invites you to go along with her in revealing the basis of her upbringing and her choices, the story itself is engaging. Readers arrive at the final chapters with an appreciation not only for the complexity of our history as individuals around race, gender and class but with real hope in education as a way to create a place where all children get a fair chance at success.

We clarify the role of the Born rule in the Copenhagen Interpretation of quantum mechanics by deriving it from Bohr's doctrine of classical concepts, translated into the following mathematical statement: a quantum system described by a noncommutative C*-algebra of observables is empirically accessible only through associated commutative C*-algebras. The Born probabilities emerge as the relative frequencies of outcomes in long runs of measurements on a quantum system; it is not necessary to adopt the frequency interpretation of single-case probabilities (which will (...) be the subject of a sequel paper). Our derivation of the Born rule uses ideas from a program begun by Finkelstein (1965) and Hartle (1968), intending to remove the Born rule as a separate postulate of quantum mechanics. Mathematically speaking, our approach refines previous elaborations of this program - notably the one due to Farhi, Goldstone, and Gutmann (1989) as completed by Van Wesep (2006) - in replacing infinite tensor products of Hilbert spaces by continuous fields of C*-algebras. In combination with our interpretational context, this technical improvement circumvents valid criticisms that earlier derivations of the Born rule have provoked, especially to the effect that such derivations were mathematically flawed as well as circular. Furthermore, instead of relying on the controversial eigenvector-eigenvalue link in quantum theory, our derivation just assumes that pure states in classical physics have the usual interpretation as truthmakers that assign sharp values to observables.

Maurice Merleau-Ponty (1908-1961) has been hailed by many as the greatest French thinker of the twentieth century. As one of the founding members of the existentialist movement in the 1940s, he played a key role in introducing the work of Husserl and Heidegger into French thought and collaborated with Jean-Paul Sartre in the founding of Les Temps Modernes. His later work laid the foundation for the development of French thought in the direction of post-structuralism and post-modernism.

Merleau-Ponty: Critical (...) Assessments of Leading Philosophers gathers together the best critical writing on Merleau-Ponty’s work from the last half century. The collection includes early reviews of his work and the reactions of his contemporaries both during and after his life. Also covered are examinations of his relationship with Husserl, Sartre and the phenomenological tradition, investigations of key themes from his work on ontology, expression and politics, and the ongoing application of his thinking to such contemporary areas of interest as feminist theory, psychology and child development, environmental philosophy and cognitive science.

This book presents a multidisciplinary perspective on chance, with contributions from distinguished researchers in the areas of biology, cognitive neuroscience, economics, genetics, general history, law, linguistics, logic, mathematical physics, statistics, theology and philosophy. The individual chapters are bound together by a general introduction followed by an opening chapter that surveys 2500 years of linguistic, philosophical, and scientific reflections on chance, coincidence, fortune, randomness, luck and related concepts. A main conclusion that can be drawn is that, even after all this time, (...) we still cannot be sure whether chance is a truly fundamental and irreducible phenomenon, in that certain events are simply uncaused and could have been otherwise, or whether it is always simply a reflection of our ignorance. Other challenges that emerge from this book include a better understanding of the contextuality and perspectival character of chance (including its scale-dependence), and the curious fact that, throughout history (including contemporary science), chance has been used both as an explanation and as a hallmark of the absence of explanation. As such, this book challenges the reader to think about chance in a new way and to come to grips with this endlessly fascinating phenomenon. (shrink)

We propose a technical reformulation of the measurement problem of quantum mechanics, which is based on the postulate that the final state of a measurement is classical; this accords with experimental practice as well as with Bohr’s views. Unlike the usual formulation (in which the post-measurement state is a unit vector in Hilbert space), our version actually opens the possibility of admitting a purely technical solution within the confines of conventional quantum theory (as opposed to solutions that either modify this (...) theory, or introduce unusual and controversial interpretative rules and/or ontologies). To that effect, we recall a remarkable phenomenon in the theory of Schrödinger operators (discovered in 1981 by Jona-Lasinio, Martinelli, and Scoppola), according to which the ground state of a symmetric double-well Hamiltonian (which is paradigmatically of Schrödinger’s Cat type) becomes exponentially sensitive to tiny perturbations of the potential as ħ→0. We show that this instability emerges also from the textbook wkb approximation, extend it to time-dependent perturbations, and study the dynamical transition from the ground state of the double well to the perturbed ground state (in which the cat is typically either dead or alive, depending on the details of the perturbation). Numerical simulations show that adiabatically arising perturbations may (quite literally) cause the collapse of the wave-function in the classical limit. Thus, at least in the context of a simple mathematical model, we combine the technical and conceptual virtues of decoherence (which fails to solve the measurement problem but launches the key idea that perturbations may come from the environment) with those of dynamical collapse models à la grw (which do solve the measurement problem but are ad hoc), without sharing their drawbacks: single measurement outcomes are obtained (instead of merely diagonal reduced density matrices), and no modification of quantum mechanics is needed.

Offering clear and reliable guidance to the ideas of philosophers from antiquity to the present day and to the major philosophical systems around the globe, he Oxford Companion to Philosophy is the definitive philosophical reference work for readers at all levels. For ten years the original volume has served as a stimulating introduction for general readers and as an indispensable guide for students and scholars. A distinguished international assembly of 249 philosophers contributed almost 2,000 entries, and many of these have (...) now been considerably revised and updated in this major new edition; to these are added over 300 brand-new pieces on a fascinating range of current topics such as animal consciousness, cloning, corporate responsibility, the family, globalization, terrorism . Here is, indeed, a world of thought, with entries on idealism and empiricism, epicureanism and stoicism, passion and emotion, deism and pantheism. The contributors represent a veritable who's who of modern philosophy, including such eminent figures as Isaiah Berlin, Sissela Bok, Ronald Dworkin, John Searle, Michael Walzer, and W. V. Quine. We meet the great thinkers--from Aristotle and Plato, to Augustine and Aquinas, to Descartes and Kant, to Nietzsche and Schopenhauer, right up to contemporary thinkers such as Richard Rorty, Jacques Derrida, Luce Iragaray, and Noam Chomsky. There are short entries on key concepts such as personal identity and the mind-body problem, major doctrines from utilitarianism to Marxism, schools of thought such as the Heidelberg School or the Vienna Circle, and contentious public issues such as abortion, capital punishment, and welfare. In addition, the book offers short explanations of philosophical terms (qualia, supervenience, iff), puzzles (the Achilles paradox, the prisoner's dilemma), and curiosities (the philosopher's stone, slime). Almost every entry is accompanied by suggestions for further reading, and the book includes both a chronological chart of the history of philosophy and a gallery of portraits of eighty eminent philosophers. An indispensable guide and a constant source of stimulation and enlightenment, The Oxford Companion to Philosophy will appeal to everyone interested in abstract thought, the eternal questions, and the foundations of human understanding.

A collection of readings by modern philosophers presents an overview of current thought and trends in the areas of morality, aesthetics, epistemology, metaphysics, logic, and theology.

In this paper, we compare and contrast two methods for the revision of qualitative beliefs. The first method is generated by a simplistic diachronic Lockean thesis requiring coherence with the agent’s posterior credences after conditionalization. The second method is the orthodox AGM approach to belief revision. Our primary aim is to determine when the two methods may disagree in their recommendations and when they must agree. We establish a number of novel results about their relative behavior. Our most notable finding (...) is that the inverse of the golden ratio emerges as a non-arbitrary bound on the Bayesian method’s free-parameter—the Lockean threshold. This “golden threshold” surfaces in two of our results and turns out to be crucial for understanding the relation between the two methods. (shrink)

Until recently, the medical community assumed that placebos required either concealment in randomized controlled trials or deception in clinical practice to elicit placebo effects. Henry Beecher emphasized this orthodoxy, when he stated that placebo pills only work "as long as it is not detected as a placebo by the subject or the observer" and therefore, patients "believe it [is a drug] and consequently the expected results occurs".

This paper seeks to establish closer connections and spur dialogue between philosophers working on 4E cognition and aestheticians. In part, the aim is to offer a critical overview of the ways 4E research might inform our understandings of the arts. Yet it is also partly to flag some potential art-specific challenges to some of the theses found within the 4E literature. I start by examining the strongest extant claims regarding art and active externalism, and argue that it is hard to (...) see either how active externalism could square with our actual appreciative practices or that its explanatory value could be sufficient to pressure us to revise radically those practices. Furthermore, I argue, rejecting active externalism seems necessary to acknowledge adequately the important ways in which artistic creation often involves the application of embodied know-how or the execution of embodied skills. For this reason, I argue, embodied approaches to cognition are better positioned to complement and inform the humanistic methods traditionally employed in philosophical aesthetics and art theory. However, I conclude on a moderately sceptical note: the challenge still outstanding for these approaches is to yield new understandings of our artistic practices that have not been gleaned through traditional humanistic inquiry.

Reason and Explanation develops a new explanationist account of epistemic justification. Poston argues that the explanatory virtues provide a plausible account of necessary and sufficient conditions for justification. The justification of a subject's belief consists in the explanatory virtue of her entire beliefs compared with other sets of beliefs she could have. Poston's argument for coherentism involves a defense of the epistemic value of background beliefs, the development of a novel framework view of reasons, and the articulation of a mentalism (...) evidentialist account of coherentism. Poston argues against foundationalist views that ground justification in sense experience apart from supporting background beliefs. He extends the argument against foundationalism by examining a coherentist view of a priori knowledge. Finally, he articulates a compatiblist position regarding Bayesianism and inference to the best explanation. (shrink)

A diverse group of DNA‐binding regulatory proteins share a common structural domain which is homologous to the sequence of a highly conserved and abundant chromosomal protein, HMG‐1. Proteins containing this HMG‐1 box regulate various cellular functions involving DNA binding, suggesting that the target DNA sequences share a common structural element. Members of this protein family exhibit a dual DNA‐binding specificity: each recognizes a unique sequence as well as a common DNA conformation.

We examine the structural and functional relationships between the proteins, identify their signature† and describe common features of their target DNA elements. (shrink)

Three experiments investigating children's understanding of inference as a source of knowledge and beliefs were used to determine whether children use a theory in understanding the mind. A child watched while a sweet was placed in a box whereas a doll was merely given a message about which sweet had been transferred. Children were asked to judge whether the doll knew the colour of the sweet in the box and what colour the do6 would think the sweet was. The main (...) finding was that children tended to say the doll would hold a false belief about the colour of the sweet whenever the doll had not looked in the box. This result is easily reconciled with the theory view as a drive for coherence within the different aspects (knowledge and belier predictions) of the child's theory of mind. The result is contrary to the simulation view because children were generally good at‘inputting’or taking account of the relevant information (i.e. the doll's knowledge of the sweets’colours and the message to the doll), because children assessed their own beliefs quite differently from the doll's beliefs, and because contrary to the default assumptions set out by Harris (1991) children found it easier to assign a false belief to the doll than to assign a true belief.

Abe and his friend Sol are out for a walk together in a part of town they haven't been in before. Passing a Christian church, they notice a curious sign in front that says "$1,000 to anyone who will convert." "I wonder what that's about," says Abe. "I think I'll go in and have a look. I'll be back in a minute; just wait for me." Sol sits on the sidewalk bench and waits patiently for nearly half an hour. Finally, (...) Abe reappears. "Well," asks Sol, "what are they up to? Who are they trying to convert? Why do they care? Did you get the $1,000?" Indignantly Abe replies, "Money. That's all you people care about." Ted Cohen thinks that's not a bad joke. But he also doesn't think it's an easy joke. For a listener or reader to laugh at Abe's conversion, a complicated set of conditions must be met. First, a listener has to recognize that Abe and Sol are Jewish names. Second, that listener has to be familiar with the widespread idea that Jews are more interested in money than anything else. And finally, the listener needs to know this information in advance of the joke, and without anyone telling him or her. Jokes, in short, are complicated transactions in which communities are forged, intimacy is offered, and otherwise offensive stereotypes and cliches lose their sting—at least sometimes. _Jokes_ is a book of jokes and a book about them. Cohen loves a good laugh, but as a philosopher, he is also interested in how jokes work, why they work, and when they don't. The delight at the end of a joke is the result of a complex set of conditions and processes, and Cohen takes us through these conditions in a philosophical exploration of humor. He considers questions of audience, selection of joke topics, the ethnic character of jokes, and their morality, all with plenty of examples that will make you either chuckle or wince. _Jokes:_ more humorous than other philosophy books, more philosophical than other humor books. "Befitting its subject, this study of jokes is... light, funny, and thought-provoking....

The current dominant perspective on addiction as a brain disease has been challenged recently by Marc Lewis, who argued that the brain-changes related to addiction are similar to everyday changes of the brain. From this alternative perspective, addictions are bad habits that can be broken, provided that people are motivated to change. In that case, autonomous choice or “free will” can overcome bad influences from genes and or environments and brain-changes related to addiction. Even though we concur with Lewis that (...) there are issues with the brain disease perspective, we also argue that pointing to black swans can be important, that is: there can be severe cases where addiction indeed tips over into the category of brain disease, but obviously that does not prove that every case of addiction falls into the disease category, that all swans are black. We argue that, for example, people suffering from Korsakoff’s syndrome, can be described as having a brain disease, often caused by alcohol addiction. Moreover, the brain changes occurring with addiction are related to choice-behaviour, habit formation and insight, hence essential mental abilities to break the addiction. We argue for a more graded perspective, where both black swans and white swans are rare, and most cases of addiction come as geese in different shades of gray. (shrink)

Jason Stanley and Timothy Williamson's influential article "Knowing How" argues that knowledge-how is a species of knowledge-that. One objection to their view is that knowledge-how is significantly different than knowledge-that because Gettier cases afflict the latter but not the former. Stanley and Williamson argue that this objection fails. Their response, however, is not adequate. Moreover, I sketch a plausible argument that knowledge-how is not susceptible to Gettier cases. This suggests a significant distinction between knowledge-that and knowledge-how.

In this book, Ted Peters explores the fallacies of the "gene myth" and presents a resounding array of arguments against this kind of all-encompassing genetic determinism. On the scientific side, he correctly points out that genetic influences on behavior are in most instances relatively modest.

After dispatching some of the sweepingly deterministic conclusions of the "science" of evolutionary psychology with a particularly effective set of rebuttals, Peters (...) arrives at the conclusion that the nature of humanness is an interaction of three things- not one, not two, but three: genetics, environment, and free will. Neglecting any one of these three leads down a path of fuzzy thinking and dangerous consequences. (shrink)

In our time, Ted Toadvine observes, the philosophical question of nature is almost entirely forgotten—obscured in part by a myopic focus on solving "environmental problems" without asking how these problems are framed. But an "environmental crisis," existing as it does in the human world of value and significance, is at heart a philosophical crisis. In this book, Toadvine demonstrates how Maurice Merleau-Ponty’s phenomenology has a special power to address such a crisis—a philosophical power far better suited to the questions than (...) other modern approaches, with their over-reliance on assumptions drawn from the natural sciences. The book examines key moments in the development of Merleau-Ponty’s philosophy of nature while roughly following the historical sequence of his major works. Toadvine begins by setting out an ontology of nature proposed in Merleau-Ponty’s first book, _The Structure of Behavior. _He takes up the theme of the expressive role of reflection in _Phenomenology of Perception, _as it negotiates the area between nature’s own "self-unfolding" and human subjectivity. Merleau-Ponty’s notion of "intertwining" and his account of space provide a transition to Toadvine’s study of the philosopher’s later work—in which the concept of "chiasm," the crossing or intertwining of sense and the sensible, forms the key to Merleau-Ponty’s mature ontology—and ultimately to the relationship between humans and nature.

'Review from previous edition 'the arguments for free will and determinism are lucidly laid out... A primer that is serviceable, enjoyable and rather mischievous.'' - The Observer 1993 ''refreshing, provocative and original work'' - Times Literary Supplement 1994 ''a readable and engaging introduction to the determinism controversy... Honderich's book is well worth reading... the view he presents is provocative and he has written a very challenging and enlightening introduction to 'the determinism problem' that should be widely read.'' - Times Educational (...) Supplement 1994 ''If you feel strong enough read this book; if not be glad that it has been written; this is main stream philosophy and its conclusions are encouraging.'' -New Directions July 2002This second edition of the best-known and most translated introduction to the great philosophical problem of determinism and freedom has been fully revised and enlarged to take account of debates emerging since the first edition was published. In the first edition Ted Honderich went beyond two traditions of philosophical thought, whilst in this edition he indicates that the nature of the debate must change. (shrink)

This essay offers an account of the relationship between screenplay and film, and it does so by comparing this relationship to the relationships that hold between other sets of instructions and artworks: score and musical work, theatrical script and theatrical work, architectural plan and architectural work. I argue that musical scores and theatrical scripts are work-determinative documents—manuscripts whose existence entails the existence of musical works and theatrical works, respectively, and which determine the facts about what those works are like. On (...) the contrary, I argue that architectural plans and screenplays are not work-determinative because they alone do not entail the existence of any architectural work or film. Nevertheless, I conclude that this difference has no bearing upon art status: theatrical scripts are almost always artworks in their own right, musical scores almost never are, and architectural plans are in certain cases. This conclusion suggests that although the relationship between theatrical script and theatrical work is quite different from that between screenplay and film, there is no reason to think that screenplays cannot be literary artworks in their own right.

I want to suggest a point in metaphor which is independent of the question of its cognitivity and which has nothing to do with its aesthetical character. I think of this point as the achievement of intimacy. There is a unique way in which the maker and the appreciator of a metaphor are drawn closer to one another. Three aspects are involved: the speaker issues a kind of concealed invitation; the hearer expends a special effort to accept the invitation; and (...) this transaction constitutes the acknowledgement of a community. All three are involved in any communication, but in ordinary literal discourse their involvement is so persuasive and routine that they go unremarked. The use of metaphor throws them into relief, and there is a point in that. An appreciator of a metaphor must do two things: he must realize that the expression is a metaphor, and he must figure out the point of the expression. His former accomplishment induces him to undertake the latter. Realizing the metaphorical character of an expression is often easy enough; it requires only the assumption that the speaker is not simply speaking absurdly or uttering a patent falsehood. But it can be a more formidable task: not every figurative expression which can survive a literal reading is a mere play on words.
