This paper gives two complete and elementary proofs that if the speed of light over closed paths has a universal value c, then it is possible to synchronize clocks in such a way that the one-way speed of light is c. The first proof is an elementary version of a recent proof. The second provides high precision experimental evidence that it is possible to synchronize clocks in such a way that the one-way speed of light has a (...) universal value. We also discuss an old incomplete proof by Weyl which is important from an historical perspective. (shrink)

The date of composition of King Horn has in recent years been moved from ca. 1225 to ca. 1250, or even as late as the 1270s, as more information about the three manuscripts of the poem has become available. Nevertheless, King Horn still seems to lie at, or at least very near, the beginning of the Middle English romance tradition, and it thus holds a special interest as a potential indicator of the way in which that tradition came into existence. (...) This paper explores one key element in King Horn as a step towards a better understanding of both the poem itself and its literary context. (shrink)

The convention that the one-way velocity of light is isotropic is shown to be independent of the postulates of relativity in a globally Minkowskian continuum, but not in a continuum which is only locally Minkowskian.

The Reichenbach-Grunbaum thesis of the conventionality of simultaneity is clarified and defended by developing the consequences of the Special Theory when assumptions are not made concerning the one-way speed of light. It is first shown that the conventionality of simultaneity leads immediately to the conventionality of all relative speeds. From this result, the general-length-contraction and time-dilation relations are then derived. Next, the place of time-dilation and length-contraction effects within the Special Theory is examined in the light of the conventionality (...) thesis. The slow-transport method of synchrony is then examined in the light of these results and is shown not to provide an adequate method of uniquely determining the one-way speed of light. Finally, the general ε -Lorentz transformations for events along the x-axis are derived from three principles: the round-trip light principle, the principle of equal passage times, and the linearity principle. These principles are shown to be independent of one-way velocity assumptions, and thus may form the basis of a Special Theory of Relativity without distant simultaneity assumptions. (shrink)

In this paper we describe a propagation experiment to measure the one-way velocity of electromagnetic radiation. The experiment utilizes the rotation of the earth to interchange the positions of two rubidium vapor frequency standards over12 h, thereby canceling initial clock phase differences. It is demonstrated that although the drift characteristics of modern rubidium atomic clocks may be large for long-term absolute timing requirements, the short-term random fluctuations are small. It is found that over a24-h period, the long-term drift can be (...) accurately parameterized in retrospect and removed, thereby permitting the detection of temporal variations less than1 nsec in magnitude. With coherent summing techniques this value may be significantly reduced, and it becomes realistic to consider an experiment where the clocks are separated by distances of the order of several hundreds of meters in order to detect velocities of the order of that of the solar system with respect to the center of the galaxy(≈10 5 m sec −1 ), thus ensuring that the rotational motion of the earth has a negligible effect in altering the relative inertial characteristics of the reference frames of each clock. It is demonstrated that under such conditions the measurement of the one-way speed of propagation of electromagnetic radiation is not only meaningful, but can be simply implemented with commercially available instrumentation.

Many philosophers have been attracted to the view that reasons are premises of good reasoning – that reasons to φ are premises of good reasoning towards φ-ing. However, while this reasoning view is indeed attractive, it faces a problem accommodating outweighed reasons. In this article, I argue that the standard solution to this problem is unsuccessful and propose an alternative, which draws on the idea that good patterns of reasoning can be defeasible. I conclude by drawing out implications for the (...) debate over pragmatic reasons for belief and other attitudes and for one influential form of reductionism about the normative. (shrink)

According to fitting-attitudes accounts of value, the valuable is what there is sufficient reason to value. Such accounts face the famous wrong kind of reason problem. For example, if an evil demon threatens to kill you unless you value him, it may appear that you have sufficient reason to value the demon, although he is not valuable. One solution to this problem is to deny that the demon’s threat is a reason to value him. It is instead a reason to (...) want to value the demon, and to bring it about that you value him. However, many proponents of the wrong kind of reason problem find this solution unmotivated. This paper thus offers a new argument for this solution. The argument turns on the ‘transmission’ of reasons – the familiar fact that there is often reason for one action or attitude because there is reason for another. I observe that putative reasons of the wrong kind transmit in a very different way to other reasons. I then argue that this difference is best explained by the hypothesis that putative reasons of the wrong kind are not reasons for the attitude in question, but are instead reasons to want and bring about that attitude.

In this paper, we claim that, if you justifiably believe that you ought to perform some act, it follows that you ought to perform that act. In the first half, we argue for this claim by reflection on what makes for correct reasoning from beliefs about what you ought to do. In the second half, we consider a number of objections to this argument and its conclusion. In doing so, we arrive at another argument for the view that justified beliefs (...) about what you ought to do must be true, based in part on the idea that the epistemic and practical domains are uniform, in a sense we spell out. We conclude by sketching possible implications of our discussion for the debates over what is wrong with akrasia and pragmatic encroachment on justified belief and knowledge. (shrink)

Perspectivists hold that what you ought to do is determined by your perspective, that is, your epistemic position. Objectivists hold that what you ought to do is determined by the facts irrespective of your perspective. This paper explores an influential argument for perspectivism which appeals to the thought that the normative is action guiding. The crucial premise of the argument is that you ought to φ only if you are able to φ for the reasons which determine that you ought (...) to φ. We show that this premise can be understood in different ways. On one reading, it provides no support for perspectivism. On another reading, the premise lacks support. So, the argument fails. An important upshot of the paper is that the objectivist can embrace the thought about guidance. (shrink)

Some irrational states can be avoided in more than one way. For example, if you believe that you ought to A you can avoid akrasia by intending to A or by dropping the belief that you ought to A. This supports the claim that some rational requirements are wide-scope. For instance, the requirement against akrasia is a requirement to intend to A or not believe that you ought to A. But some writers object that this Wide-Scope view ignores asymmetries between (...) the different ways of avoiding irrationality. In this paper I defend the Wide-Scope view against recent objections of this sort from Mark Schroeder and Niko Kolodny. I argue that once we are clear about what the Wide-Scope view is committed to—and, importantly, what it is not—we can see that Schroeder and Kolodny’s objections fail. (shrink)

During development one mechanism for generating different cell types is asymmetric cell division, by which a cell divides and contributes different factors to each of its daughter cells. Asymmetric cell division occurs through out the eukaryotic kingdom, from yeast to humans. Many asymmetric cell divisions occur in a defined orientation. This implies a cellular mechanism for sensing direction, which must ultimately lead to differences in gene expression between two daughter cells. In this review, we describe two classes of molecules: regulatory (...) factors that are differentially expressed upon asymmetric cell division, and components of a signal transduction pathway that may define cell polarity. The lin‐11 and mec‐3 genes of C. elegans, the Isl‐1 gene of mammals and the HO gene of yeast, encode regulatory factors that determine cell type of one daughter after asymmetric cell division. The CDC24 and CDC42 genes of yeast affect both bud positioning and orientation of mating projections, and thus may define a general cellular polarity. We speculate that molecules such as Cdc24 and Cdc42 may regulate expression of genes such as lin‐11, mec‐3, Isl‐1 and HO upon asymmetric cell division. (shrink)

Asymmetric cell division generates two cells that contain different regulatory proteins and express different fates. In an example of asymmetric cell division from B. subtilis, a site on the membrane of the dividing cell is chosen to establish the initial asymmetry. Recent results(1,2) show that a key regulatory protein, SpollE, is localized to one side of a sporulating B. subtilis cell, and subsequently functions in an asymmetric manner. SpollE is a phosphatase at the beginning of a regulatory cascade that leads (...) to activation of a cell fate‐determining transcription factor in only one daughter cell. (shrink)

What should I do? What should I think? Traditionally, ethicists tackle the first question, while epistemologists tackle the second. Philosophers have tended to investigate the issue of what to do independently of the issue of what to think, that is, to do ethics independently of epistemology, and vice versa. This collection of new essays by leading philosophers focuses on a central concern of both epistemology and ethics: normativity. Normativity is a matter of what one should or may do or think, (...) what one has reason or justification to do or to think, what it is right or wrong to do or to think, and so on. The volume is innovative in drawing together issues from epistemology and ethics and in exploring neglected connections between epistemic and practical normativity. It represents a burgeoning research programme in which epistemic and practical normativity are seen as two aspects of a single topic, deeply interdependent and raising parallel questions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Parenting Children With Autism Spectrum Disorders Through the Transition to AdulthoodAnonymous One, Anonymous Two, Lorri Centineo, Anonymous Three, Virginia Clapp, Catherine Cornell, Nancy Coughlin, David McDonald, Mark Osteen, Laura Shumaker, Julie Van der Poel, Anonymous FourMy Son's Life with Autistic Spectrum DisorderAnonymous OneThis is the story of how my son, David, has tried to become independent. David is now 25–years–old. His immediate family is his dad, a brother (age (...) 22) and myself (his mother). He was diagnosed with an autism spectrum disorder (ASD) when he was 13. We looked up all the information and decided not to make a big deal of it. Looking back, he displayed all the classic signs of a high functioning autistic disorder. Would he have been diagnosed with the new DSM 5 guidelines? He probably would have. His life would be much, much different if he had been diagnosed at an early age.I'll start with David at age 13 when he was able to harness his big interest in computer science into a career for himself. He was expelled from middle school for threatening some kid that had been picking on him all year. He had a meltdown and wasn't able to communicate his side of the story and that was it.During the summer of that year he took classes in computer engineering (Microsoft) and became an engineer when he was 13. At that time it was quite an accomplishment because he was the youngest person in the United States to do so at such a young age. (By the way, the administration of the school that expelled him sent him a congratulatory card when he was written up in the paper).His father and uncle are in business running a computer company so David had a ready–made job waiting for him when he graduated from high school and was able to keep it during difficult times. David finished high school (mainstreamed special education as emotionally disturbed) and he also received another engineering certification (Cisco).I have to mention here that I truly did not understand what it was like for my son until one day when he was in high school, as I was lecturing him again for some stupid reason, he said, "You don't know how hard it is for me to not sit in a corner and rock every day." Think about that. ASD individuals get up and keep going every day when they know they are going to be misunderstood and picked on. They all deserve a medal for bravery.David became really upset that he had never had a date and that girls were not even interested in talking to him. He started cutting himself and shaving his head. That got him some attention from the stoner group. He had someone to sit with at lunch anyhow. Parents, I think it's better to have no friends than the wrong friends. They introduced him to drugs.We did not mention any trouble David was having to any relatives. We had lived 800 miles from our families in a very unspoiled part of northern America. In hindsight this was not good either. [End Page 151]Another thing, and I think every parent will agree with this—teachers, school staff, health care industry staff, doctors and every one that comes into contact with an ASD individual—take the time to get to know them. It may be difficult and some may appear non–caring and rude. You must overlook this and look to the person underneath. They are great people. They have been through stuff and it means so much to them. Like I said—parents, you know this. Please remember it when times get tough.During David's senior year he started work release so he could start earning money to buy a car and move out as soon as he turned 18. Things were made easy for David since the company was owned by his father and his uncle and I worked there also. David enjoyed the work but had the occasional meltdown and had difficulties fitting in with other employees. He wasn't able to communicate... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:My Story:Evolving ObesitiesAnonymous OneI am a 66–year–old Caucasian woman. I have always had, either in perception or fact, a “weight problem.” In my childhood and early teens when my weight was within the normal range, I felt fat and was always trying to lose weight. After gaining weight in college, I had a weight problem in body as well as mind. Weight concerns have consumed much of my energy (...) over the years. I have spent most of my life evolving toward a healthy way to manage my weight.Act 1: Obesity as MetaphorI can’t remember ever not feeling fat. Growing up I felt humiliated and shamed by my body, even though I was not overweight, just bigger than my peers, with a pear shape and heavy legs, thighs, and ankles. In high school my BMI, although not used at the time as a measuring tool, was 22.8. Yet despite these facts, I was made to feel fat.In my family being overweight was tantamount to sin. My father and sister were tall and skinny; my mother was petite and shapely. I took after another genetic code—the dumpy ones with knocked knees—the grotesque branch of the family tree. Hand–me–downs from my sister were supposed to fit me, but we were too different, and the difference was not celebrated.Other things were at play, a perfect storm of conditions that contributed to my feelings of worthlessness. I really shouldn’t have been born. The earth should have opened up and swallowed me. Of course I was not conscious of reasons for these feelings at the time. That awareness came later. But these feelings of loss, grief, terror, and terrible wrongness were the context of my struggles over the years.I developed a pattern of binge eating, which satisfied two contradictory impulses: my need to nurture myself combined with my desire to punish myself. The intensity of a binge–eating episode was also an avenue for rage. I was young so the extra calories didn’t result in weight gain, but the behavior had begun to take root.Stepping on the scale was like the final judgment. The scale did not measure weight; it measured value. I would see the number, as would the person weighing me, and my failure, as a person, would be evident. My secret shame would become public. I would be declared guilty for the worthless grub that was me.Nothing else mattered: that I was an A student; that I was kind and compassionate; that I had friends. These facts had no bearing. All that counted was the number on the scale. That number sent a shudder of condemnation down to my very soul. That number threatened to hurl me into a bottomless abyss from which I could not escape.I avoided being weighed. I was a very obedient youth, with an exaggerated respect for authority drilled into me by my father. The one time I ever cut class was in high school. I skipped health class where I had heard we would be weighed.The situations when I could not avoid being weighed confirmed my worst fears. Before one gym class we were publicly weighed in [End Page 96] assembly–line fashion. As I stepped off the scale my gym teacher yelled out “Diet” for all to hear. Doctors who knew nothing about me, to whom I had been sent for various required physicals, told me to lose weight.In the mysterious and internally logical way that the mind works, my weight became a metaphor for all that was reprehensible in me. With no comprehension of why I was so unhappy, it was easy for me to fixate on my weight. It was too horrible to contemplate that I was the problem. The problem with me was my size, my body.As I look back now, I am angry that because of its shape, this perfectly wonderful body was judged as wrong, and that there was no compassionate voice loud enough to contradict this message. But at the time I felt no anger. To feel anger over being made to feel bad requires self–respect... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:What Power Do I Have? A Nursing Student’s Concerns Lead to a Passion for EthicsAnonymous OneThe day began like many in our ten–week rotation, around the large table in the brightly lit ICCU nurses’ station. Report, which was given by the night charge nurse, included information on all the patients on the unit. Since I had cared for A. G. the previous day, I was eager to know how (...) she had spent the night. She had a debilitating neuro–muscular disease known as myasthenia gravis. Placed on the ventilator days before, it was reported that she was likely to be dependent on the machine for life. In the late 1970’s there were very few facilities that accepted ventilator dependent patients. She might be with us for a long time.When I entered her room for the first time, I saw a frail older woman with kind eyes and a warm smile. She was breathing with the help of the ventilator through her tracheostomy tube. I learned through her chart that she had no known family. On the day I took care of her, no one came to see her and she had no visitors the previous evening. She lived in a local long–term care facility and was brought to the hospital after she developed respiratory distress. A. G. was unable to move in the bed due to her condition and required frequent suctioning along with turning and repositioning for comfort.Despite her weakness, A. G. was able to communicate silently by mouthing the words for what she wanted and by nodding and shaking her head. I found her to be quite skilled in non–verbal [End Page 93] communication since it took minimal effort to understand what she wanted, but the activity tired her easily. I had just completed A. G.’s morning care when her physician came in to examine her. After completing his assessment, he stopped and leaned in closely to speak with her. He began asking a number of questions about whether she wanted to spend the rest of her life in this way, on a ventilator. She shook her head. Continuing the line of questioning in different ways, she responded to him. I wondered why he was asking these questions. After seeing her response, the physician asked me to get 30 mg of morphine from the narcotics cabinet. Although I didn’t understand the implication of the request, I complied.While I was retrieving the medication from the narcotics cabinet, the charge nurse came to tell me I was being reassigned to a new admission. When I asked why, she told me she couldn’t discuss it, but asked me to please do what she said. I left her standing there, wondering what was going on. After assisting with the new admission, I went back to see A.G.; her door was closed. When I opened the door, the ventilator tubing hung over the side of the machine. Looking down at the bed, I was shocked to find A.G. had been disconnected. She was dead. In a state of disbelief and panic, I sought out the charge nurse to find out what happened. It was clear that I was not to know. I asked her a number of questions but she adeptly changed the subject and redirected me to other activities. By then it was lunchtime and my instructor had left the unit. I asked to be excused and went to seek her out.When I told my instructor what happened, a look of doubt came over her face. “You think Doctor M. killed your patient? That would never happen.” Although I tried to tell her the story, she too, dismissed me, telling me my story didn’t make sense. I was distraught. An overwhelming sense of dread came over me and I began to cry. She encouraged me to go home, which I did.Happily, I had the weekend to recover before returning to clinical. I never found out what happened to A. G. and neither my instructor nor the charge nurse ever spoke to me about my experience. In fact, it seemed no one believed my story... (shrink)

In this paper, I stress the utility of employing test-driven development (TDD) for conceiving logical systems. TDD, originally invented in the context of Extreme Programming, is a methodology widely used by software engineers to conceive and develop programs. Its main principle is to design the tests of the expected properties of the system before the development phase. I argue that this methodology is especially convenient in conceiving applied logics. Indeed, this technique is efficient with most decidable logics having a software (...) implementation. Having a clear list of the desired inferences right from the beginning makes it possible to refine the properties of the system step by step until its completion. I distinguish and detail seven advantages of the usage of TDD for the conception of a logical theory. Most importantly, this methodology increases the predictability of the inferential power of the theory. A second important benefit is that the time required for the conception of the logic goes down dramatically. This methodology will change both ideas and practices. Logic is no longer considered to be a formal science, but rather to be an empirical one. Research in the field is geared toward specific and concrete goals. Programs are considered tools used to verify the conformity of formal theories. To sum up, I defend the view that, in some situations, this way of designing a formal system brings significant benefits, and that the construction of new logics can be conducted similarly to the development of open source software.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 26.2 (2002) 334-345 [Access article in PDF] Philosophy After Joyce:Derrida and Davidson Reed Way Dasenbrock A GOOD DEAL OF ATTENTION has been paid to James Joyce's influence on literature. Few novelists in the twentieth century have escaped Joyce's influence one way or another, and Robert Martin Adams has even dedicated a book, AfterJoyce, 1 to the proposition that the history of prose fiction is most properly (...) divided into two eras, before and after Joyce. One suspects that Joyce would have appreciated Adams's quasi-blasphemous periodizing.My focus here is Joyce's influence on a different intellectual and cultural realm, philosophy. Joyce's impact on philosophy clearly has not been of the same magnitude. Joyce is not one of those rare figures who have spanned fields or been as important an influence in another field as in his own, unlike Nietzsche, say, or a figure of concern to us here, Jacques Derrida. Joyce's impact on philosophy, thus, is not epoch-changing or field-changing in the way his impact on literature is. Wittgenstein and Heidegger are the two philosophers in the twentieth century whose work have comparably been assessed as epoch-changing. It is worth noting that both men are close contemporaries of Joyce: Wittgenstein, in particular, with his multilingual, Austro-Hungarian, and pan-European character, orientation towards the arts, defiance of so many philosophical conventions, and self-awareness of language, offers a fascinating parallel with Joyce, a parallel already explored to [End Page 334] some extent in the literature. If Joyce, Stravinsky, Picasso, and Le Corbusier, for example, can be said to exemplify modernist literature, music, painting, and architecture, then Wittgenstein is the exemplification of modernist philosophy. But Modernism, or at least so we are told, is out of fashion and out of date, yet Joyce remains our contemporary in ways many of his fellow modernists may not. Nowhere is this more clearly shown than in his continuing presence in contemporary philosophy.The conventional way of writing the history of philosophy in the twentieth century is to divide it into two camps, one oriented towards mathematics, science and logical analysis, a school of philosophy called the analytic or Anglo-American school, the other oriented towards literature and culture and an engagement with the history of philosophy, called the Continental school. That there are a number of problems with this way of mapping the field is by now widely accepted, but no one has successfully replaced this division with anything generally seen to be more adequate, so we continue to use the terms, if as Derrida might say "under erasure." If contemporary analytic philosophy has a single leading figure, I would assign that position to Donald Davidson; continental philosophy has distinct German and French variants, but clearly foremost on the French side is Jacques Derrida. One of the factors leading to our awareness that this bipolar model of the history of twentieth-century philosophy doesn't work very well has been a body of work pointing out a number of similarities between the work of these two philosophers. 2 But what hasn't been pointed out is that both philosophers are interested in Joyce. Thus, the work of Joyce is one of the places the two currents of philosophy merge or at least come into contact. In my opinion, neither Derrida nor Davidson is or deserves to be a crucial figure in Joyce criticism, but looking at their interest in Joyce allows us to trace a neglected chapter in Joyce's influence on the culture and thought of our time and to assess the similarities and differences between the work of these two philosophers.Derrida's work on Joyce includes two essays on Joyce, one an address to the 1984 Joyce Symposium in Frankfurt, "Ulysses Gramophone: Hear say yes in Joyce," 3 an essay which Margot Norris included in A Companion to James Joyce's Ulysses (in abridged form) as one of five exemplary or representative pieces of theoretical approaches to Ulysses (representing deconstruction, of course), and an earlier essay on Finnegans Wake, "Two Words for Joyce...

This article uses the ‘Ticking Bomb Scenario’ as a starting point for a broader discussion of what I term the ‘liberal narrative of speed’, the argument within liberal thought that the accelerating pace of events in the world requires a transition of authority from slow-moving, democratic legislative bodies, to energetic, efficient and unitary executives. However, this article argues that the source of this transfer of power is not because of any structural misfit between democracy and acceleration . Instead, through (...) an investigation of the ontology of speed I argue that speed produces not a functional threat to democratic politics, but an existential one. Acceleration unsettles stable political identities, and produces a time of uncertainty, in which people are wary of engaging in democratic debate and compromise, preferring instead the certainty of unitary executive leadership. In this regards the anti-democratic tendency of acceleration is to be located in the way in which it inculcates a sense of ressentiment against a future that is contingent and uncertainty. (shrink)

The most recent attempt at factually establishing a "true" value for the one-way velocity of light is shown to be faulty. The proposal consists of two round-trip photons travelling first in vacuo and then through a medium of refractive index n before returning to their common point of origin. It is shown that this proposal, as well as a similar one considered by Salmon (1977), presupposes that the one-way velocities of light are equal to the round-trip value. Furthermore, experiments of (...) this type, involving regions of space with varying refractive indices, cannot "single out" any factual value for the Reichenbach-Grünbaum ε factor thus posing no threat to the conventionalist thesis.

In a previous work, we have shown that the null result of the Michelson–Morley experiment in vacuum is deeply connected with the notion of time. The same is true for the postulate of constancy of the two-way speed of light in vacuum in all frames independently of the state of motion of the emitting body. The argumentation formerly given is very general and has to be true not only within Special Relativity and its “equivalence” of all inertial frames, but (...) as well as in Lorentz-Poincaré scenario of a preferred reference frame. This paper is the second of a trilogy intending to revisit the foundations of Special Relativity, and addresses the question of the constancy of the one-way speed of light and of the differences and similarities between both scenarios. Although they manifestly differ in philosophy, it is debated why and how the assumption of a “special system of reference experimentally inaccessible” is indeed compatible with Einstein’s Special Relativity, as beautifully outlined and discussed by Bell [Speakable and Unspeakable in Quantum Mechanics (Cambridge University Press, Cambridge, 1988)]. This rather trivial statement is still astonishing nowadays to a big majority of scientists. The purpose of this work is to bring such assertion into perspective, widening the somewhat narrow view of Special Relativity often presented in textbooks and scientific papers. (shrink)

Problem solving can be readily described as one of the key activities regularly performed by professionals in any workplace setting. Despite its importance, however, there is relatively little linguistic research which looks at the complex ways in which problems are constructed in discourse. This article sees the enactment of a ‘problem’ as a discursive phenomenon with fluid boundaries. It draws on business meeting data recorded in multinational companies in Europe and focuses on excerpts identified by the participants as having a (...) PbS function. The data show that problem solving processes and practice are anchored to the structure of the organizations, the local history and employees’ shared perceptions of professional practices and hierarchies in their workplace. The analysis also shows two focal points in the PbS talk of the participants in this study, namely identification of a problem and its ownership. These, however, are not predetermined starting points but rather locally constructed in relation to the status, expertise and shared/past history of the interactants. (shrink)

The curvature of the earth is causing you to shift away from the pinpoint that you circled yesterday on a map, your eyes hazed. That was also a today, in a novel fashion—the today of days long gone, of clouds long transformed into rain, or else snow drifts. That’s okay, you know this: in cathedrals of bone we find arcs that keep us warm. In drift- wood we find the puzzles that madden us all night, Tetris dreaming. In from our past, deriving steam, straight lines, axes, branches, kindling. Attention! Does anyone here speak Spanish? Si? Bueno! Dream with me. Cry out in your sleep. Step fearfully out onto the ice and drift awhile, inside a massive Perspex speech-bubble dream. A massive bubble longing to become detergent. The louvres of a ribcage snapping shut. Awe. Curvature of the earth is a con job: ask a dervish. Hail an imaginary cab in a hail-struck avenue and wait for the popcorn to drop. Stop, drifter! In the pharmacies and in the alleys, popping rocks while money men drift by in stockings, purling and unfurling their ways, their means. Attention, people!ion hurts. Reading too much into things I know nothing about, the niceness of the void or else a philosopher’s mouth sewn shut. I know about that, at least: the madness of seeking asylum in antipodean dreams, drifting for weeks at a time on a boat more abstract than surreal. Oh, fuck Life of Pi! Heaven basks like a warm, square meal but I can’t get there from here. There is no shark travelling at speed X while I zoom at speed Y in the opposite direction. I can’t use a lasso. I no longer have fits. I am no, mad. Too bad. Attention! Ambient doom slash moon. Over! The curvature of a yawn, a dream sewn shut. This skin, that knows my dreams, forgets me. Fruit tingles, wet on the tongue: get me some analogue hits, expressways to frozen, lakeside moon-dream voiceovers. The narrator’s cues infuse the afternoon, the canoes, with nostalgia. Somewhere, out there, we become driftories. We lie down in atoms and the clinamina bore. We fight against our own handwritten lies, type marching letters into files and save. Awe. Fidelity is a kind of surveillance. Current A. Attention! It was never my intention to score cheap points at the expense of polar bears, of driftwood, shores. The cockatoos roar. Their explosive chatter could strip a pine tree raw. Implant in me some destructive grace, to drift. Planetoid lamps all along the turnpike’s busy arcs. Extreme emissions of things. Drift-rings. The target of my gaze, sewn shut. Your eyes rising slower than a star from what you read, condensed into steam, here, north of all music. Driftories, signal fires, smoke: disappear. Go back to sleep now. No, we were never here. (shrink)

Did the first men dream their voyages before making them? Or did they have to first take to the sea so as to be able to later embark on the ship of their imagination and thus embroider on accounts of their journeys? Is it the prestige of the dream that spurred them on to run the risk of translating it into a real experience? Or is it the account of authentic voyages that supported that of imaginary voyages? These are questions (...) that make one dream and that we continue to ask ourselves, even though we suspect that they are idle, since it is impossible to answer them with certitude. All that we know, or think we know, is that among the first written testimonies that have come down to us, real and imaginary voyages are mixed and confused in an alloy of a homogeneity that resists analysis and is perhaps an image of the reception they had from their original public. Who knows if the Greeks who listened in the middle of the first millennium B.C. to the poets singing the return of Ulysses to Ithaca, could, or wanted to, untangle the part of truth from that of poetry? Who knows if the Arabs who, at the end of the following millennium heard the enchanting tale of the voyages of Sinbad, distinguished, as the Western orientalists of the 19th century must have done, the real ports of call and the shipwrecks experienced in the dreamed places and fantastic adventures?

Humans and animals make inferences about the world under limited time and knowledge. In contrast, many models of rational inference treat the mind as a Laplacean Demon, equipped with unlimited time, knowledge, and computational might. Following H. Simon's notion of satisficing, the authors have proposed a family of algorithms based on a simple psychological mechanism: one-reason decision making. These fast and frugal algorithms violate fundamental tenets of classical rationality: They neither look up nor integrate all information. By computer simulation, the (...) authors held a competition between the satisficing "Take The Best" algorithm and various "rational" inference procedures. The Take The Best algorithm matched or outperformed all competitors in inferential speed and accuracy. This result is an existence proof that cognitive mechanisms capable of successful performance in the real world do not need to satisfy the classical norms of rational inference. (shrink)

Stephen Neale presents, in Facing Facts (Oxford: Clarendon Press, 2001), one convenient package containing his reasoned complaints against theories of facts and non-extensional connectives. The slingshot is a powerful argument (or better, it is a powerful family of arguments) which constrains theories of facts, propositions and non-extensional connectives by showing that some of these theories are rendered trivial. This book is the best place to find the state of the art on the slingshot and its implications for logic, language and (...) metaphysics. It provides a useful starting point for anyone who has wondered what all of the fuss about the slingshot amounts to. Neale shows that the fuss does amount to something, and that theories of facts must “face facts” and present an adequate response to the slingshot. However, Neale’s evaluation of the state of play for theories of facts is too pessimistic. As the book draws near to a close, Neale writes: As I have stressed, Russell’s Theory of Facts, according to which facts have properties as components, is safe. It is certainly tempting to draw the moral that if one wants non-collapsing facts one needs properties as components of facts. I have not attempted to prove this here, but I suspect it will be proved in due course. (page 210) Neale concludes that while theories which take facts to be structured entities are safe from slingshot arguments, and he suspects that this is the only kind of fact theory safe from slingshot-style collapse. If this were the case, then theories such as situation theories or accounts of truthmakers may well be threatened. However, Neale’s suspicion is ill-founded, as I shall soon show. Not only do Russellian theories of facts survive the slingshot unscathed, but so can theories of facts which take them to be unstructured entities. Furthermore, the way that this may be not only argued for, but proved can provide a new weapon in the armoury of the theorist investigating fact theories. (shrink)

After discussing in the first five sections the meaning and the difficulties of the principle of relativity we present a new sel of spacetime transformations between inertial systems (“inertial” transformations), based on three assumptions: (1) The two-way velocity of light is c in all inertial systems and in all directions; (2) Time dilation effects take place with the usual relativistic factor; (3) Clocks are synchronized in the way chosen by nature itself, e.g., in the Sagnac effect. We show that our (...) new transformation laws can explain the available experimental evidence in spite of the implied noninvariance of the one-way velocity of light. (shrink)

The article inquires into some of the most relevant current transformations of the idea of the social in contemporary European welfare capitalism. Some crucial institutional ideas — employability and activation — of EU welfare capitalism and their connections with the new spirit of capitalism — network capitalism — are discussed. In particular, the way these ideas contribute to enacting institutional regimes of justification, framing in this a new idea of the social, is explored. The features of the latter will be (...) deepened with particular concern for two constitutive elements of European societal self-representation — individualization (as a social ideal and project) and publicness (as a fundamental characteristic of the institutional programme) — and regarding emerging paradoxes characterizing their current development. Arguments will be advanced in order to show that the currently dominant institutional regime of justification does not have a univocal, one-way fate of development, and both ties and opportunities are reconfigured. The idea of the social, even if reframed according to the social and institutional logics the article explores, is a terrain of (cultural, political, social and institutional) conflict. In this, possible counter-factual interpretations of the emerging institutional devices and practices, already at work on the social stage, can be further developed and strengthened. (shrink)

Using Finsler brane solutions [see details and methods in: S. Vacaru, Class. Quant. Grav. 28:215001, 2011], we show that neutrinos may surpass the speed of light in vacuum which can be explained by trapping effects from gravity theories on eight dimensional (co) tangent bundles on Lorentzian manifolds to spacetimes in general and special relativity. In nonholonomic variables, the bulk gravity is described by Finsler modifications depending on velocity/momentum coordinates. Possible super-luminal phenomena are determined by the width of locally anisotropic (...) brane (spacetime) and induced by generating functions and integration functions and constants in coefficients of metrics and nonlinear connections. We conclude that Finsler brane gravity trapping mechanism may explain neutrino super-luminal effects and almost preserve the paradigm of Einstein relativity as the standard one for particle physics and gravity.

A realidade do mundo contemporâneo está marcada, em grande parte, pela fragilidade das opções pessoais, pela velocidade das conexões tecnológicas e pela superficialidade das relações sociais. Nesse contexto encontra-se a educação, que, mediada por uma diversidade de processos pedagógicos, busca contribuir com a formação pessoal e a transformação social. No processo educacional, a mística, como uma energia qualificada, pode aprofundar as singularidades vividas e as sociabilidades vivenciadas, tendo como suporte de entendimento a metáfora das tendas e caminhos. As tendas são (...) entendidas como espaços privilegiados para vivenciar a pertença qualificada, a presença relacional e a participação cooperativa, e os caminhos são movimentos para contemplar a realidade, peregrinar da companhia do outro e encontrar o sentido como horizonte do caminho. Com base nessa relação dialógica, a educação é convidada a seguir caminhos que locomovem nossos corpos e movem novas ações na direção de um projeto educacional mais significativo, bem como descobrindo pela educação que somos capazes de acolher, nas tendas, a ternura e a energia, a interioridade e a exterioridade, a singularidade e a diversidade. Palavras-chave: Educação. Mística. Tendas. Caminhos.The reality of the contemporary world is marked, in great part, by the fragility of personal options, by the speed of technological connections and by the superficiality of social relations. In this context there is education, which mediated by a diversity of pedagogic processes, looks to contribute to the personal formation and social transformation of the individual. In this educational process, the mystic as a qualified energy, can deepen the peculiarities that touch a life and the social experiences through which one passes. Here, we use as a support the tents and paths metaphor. The tents can be comprehended as privileged spaces in which to experience the membership qualified, the relational presence and the cooperative participation, and the paths are movements through which one may contemplate reality, wandering with the company of others and finding a path to the horizon. Based on this dialogic relationship, education is perceived as a tool by which to follow the ways in which our bodies move around and perform new actions in the direction of the most significant educational projects, as well as discovering through this education that we are able to welcome, in the tents, the gentleness and the energy, the interiority and the appearance, the peculiarity and the diversity. Key words: Education. Mystic. Tents. Ways. (shrink)

As is well know from Einstein the choice of a criterion for distant simultaneity is equivalent to stipulating one-way speeds for the transit of light. It is shown that any choice of non-standard synchrony is equivalent to a Lorentz local time boost. From this and considerations from the hole argument, it follows that there is a non-trivial sense in which distant simultaneity is conventional, at least to the extent that the “gauge freedom” arising in the hole argument is non-trivial.

This study provides the historical background to, and analysis and translations of, two seminal texts from the medieval Islamic world concerning the univocity of being/existence and a theory of “ambiguous predication” (tashkīk), which is similar to the Thomistic theory of analogy. The disputants are Fakhr al-Dīn al-Rāzī (1149–1210), who defended a theory of the univocity of being, and Naṣīr al-Dīn al-Ṭūsī (1201–1274), who defended the theory of ambiguous predication. While the purported issue is whether a quiddity can cause its own (...) existence, the debate extends further. Rāzī draws on several arguments that “existence” must be predicated univocally of God and creature and then concludes that, given the univocity of “existence,” God cannot be simple, but is a composite of the divine quiddity and distinct attributes. In contrast, Ṭūsī denies that “existence” is said univocally of God and creature and rather is predicated ambiguously/analogously, and then defends divine simplicity. (shrink)

Frost's claim that universal models of reading require linguistically diverse data is relevant and justified. We support it with evidence demonstrating the extent of the bias towards some Indo-European languages and alphabetic scripts in scientific literature. However, some of his examples are incorrect, and he neglects the complex interaction of writing system and language structure with history and cultural environment.
