: Results of a search for the electroweak associated production of charginos and next-to-lightest neutralinos, pairs of charginos or pairs of tau sleptons are presented. These processes are characterised by final states with at least two hadronically decaying tau leptons, missing transverse momentum and low jet activity. The analysis is based on an integrated luminosity of 20.3 fb−1 of proton-proton collisions at recorded with the ATLAS experiment at the Large Hadron Collider. No significant excess is observed with respect to the (...) predictions from Standard Model processes. Limits are set at 95% confidence level on the masses of the lighter chargino and next-to-lightest neutralino for various hypotheses for the lightest neutralino mass in simplified models. In the scenario of direct production of chargino pairs, with each chargino decaying into the lightest neutralino via an intermediate tau slepton, chargino masses up to 345 GeV are excluded for a massless lightest neutralino. For associated production of mass-degenerate charginos and next-to-lightest neutralinos, both decaying into the lightest neutralino via an intermediate tau slepton, masses up to 410 GeV are excluded for a massless lightest neutralino.[Figure not available: see fulltext.].

It is shown that the logical truth of instances of the T-schema is incompatible with the formal nature of logical truth. In particular, since the formality of logical truth entails that the set of logical truths is closed under substitution, the logical truth of T-schema instances entails that all sentences are logical truths.
In the 2005 Kitzmiller v Dover Area School Board case, a federal district court ruled that Intelligent Design creationism was not science, but a disguised religious view and that teaching it in public schools is unconstitutional. But creationists contend that it is illegitimate to distinguish science and religion, citing philosophers Quinn and especially Laudan, who had criticized a similar ruling in the 1981 McLean v. Arkansas creation-science case on the grounds that no necessary and sufficient demarcation criterion was possible and (...) that demarcation was a dead pseudo-problem. This article discusses problems with those conclusions and their application to the quite different reasoning between these two cases. Laudan focused too narrowly on the problem of demarcation as Popper defined it. Distinguishing science from religion was and remains an important conceptual issue with significant practical import, and philosophers who say there is no difference have lost touch with reality in a profound and perverse way. The Kitzmiller case did not rely on a strict demarcation criterion, but appealed only to a “ballpark” demarcation that identifies methodological naturalism as a “ground rule” of science. MN is shown to be a distinguishing feature of science both in explicit statements from scientific organizations and in actual practice. There is good reason to think that MN is shared as a tacit assumption among philosophers who emphasize other demarcation criteria and even by Laudan himself. (shrink)
My purpose in what follows is not so much to defend the basic principle of utilitarianism as to indicate the form of it which seems most promising as a basic moral and political position. I shall take the principle of utility as offering a criterion for two different sorts of evaluation: first, the merits of acts of government, social policies, and social institutions, and secondly, the ultimate moral evaluation of the actions of individuals. I do not take it as implying (...) that the individual should live his life on the basis of constant evaluations of this sort. For there are different levels of decision making each with its appropriate criteria. For example, we each inevitably make many of our decisions from the point of view of our own personal self-fulfilment and this cannot regularly take a directly utilitarian form, nor should the utilitarian want it to do so. His claim is at most that we should sometimes review our life from the point of view of a kind of impersonal moral truth of a universalistic utilitarian character. (shrink)
What is a natural kind ? As we shall see, the concept of a natural kind has a long history. Many of the interesting doctrines can be detected in Aristotle, were revived by Locke and Leibniz, and have again become fashionable in recent years. Equally there has been agreement about certain paradigm examples: the kinds oak, stickleback and gold are natural kinds, and the kinds table, nation and banknote are not. Sadly agreement does not extend much further. It is impossible (...) to discover a single consistent doctrine in the literature, and different discussions focus on different doctrines without writers or readers being aware of the fact. In this paper I shall attempt to find a defensible distinction between natural and non-natural kinds. (shrink)
Abstract I argue that the two primary motivations in the literature for positing seemings as sui generis mental states are insufficient to motivate this view. Because of this, epistemological views which attempt to put seemings to work don’t go far enough. It would be better to do the same work by appealing to what makes seeming talk true rather than simply appealing to seeming talk.

It is fortunate for my purposes that English has the two words ‘almighty’ and ‘omnipotent’, and that apart from any stipulation by me the words have rather different associations and suggestions. ‘Almighty’ is the familiar word that comes in the creeds of the Church; ‘omnipotent’ is at home rather in formal theological discussions and controversies, e.g. about miracles and about the problem of evil. ‘Almighty’ derives by way of Latin ‘omnipotens’ from the Greek word ‘ pantokratōr ’; and both this (...) Greek word, like the more classical ‘ pankratēs ’, and ‘almighty’ itself suggest God's having power over all things. On the other hand the English word ‘omnipotent’ would ordinarily be taken to imply ability to do everything; the Latin word ‘omnipotens’ also predominantly has this meaning in Scholastic writers, even though in origin it is a Latinization of ‘ pantocratōr ’. So there already is a tendency to distinguish the two words; and in this paper I shall make the distinction a strict one. I shall use the word ‘almighty’ to express God's power over all things, and I shall take ‘omnipotence’ to mean ability to do everything. (shrink)
Recent and puzzling experimental results suggest that people’s judgments as to whether or not an action was performed intentionally are sensitive to moral considerations. In this paper, we outline these results and evaluate two accounts which purport to explain them. We then describe a recent experiment that allegedly vindicates one of these accounts and present our own findings to show that it fails to do so. Finally, we present additional data suggesting no such vindication could be in the offing and (...) that, in fact, both accounts fail to explain the initial, puzzling results they were purported to explain.

Green agrees with Kant on the abstract character of moral law as categorical imperatives and that intentional dispositions are central to a moral justification of punishment. The central problem with Kant's account is that we are unable to know these dispositions beyond a reasonable estimate. Green offers a practical alternative, positing moral law as an ideal to be achieved, but not immediately enforceable through positive law. Moral and positive law are bridged by Green's theory of the common good through the (...) dialectic of morality. Thus, Green appears to offer an alternative that remains committed to Kantian morality whilst taking proper stock of our cognitive limitations. Unfortunately, Green fails to unravel fully Kant's dichotomy of moral and positive law that mirrors Green's solution, although Green offers a number of improvements, such as the importance of the community in establishing rights and linking the severity of punishment to the extent that a criminal act threatens the continued maintenance of a system of rights.

Ted T. Aoki, the most prominent curriculum scholar of his generation in Canada, has influenced numerous scholars around the world. Curriculum in a New Key brings together his work, over a 30-year span, gathered here under the themes of reconceptualizing curriculum; language, culture, and curriculum; and narrative. Aoki's oeuvre is utterly unique--a complex interdisciplinary configuration of phenomenology, post-structuralism, and multiculturalism that is both theoretically and pedagogically sophisticated and speaks directly to teachers, practicing and prospective. Curriculum in a New Key: The (...) Collected Works of Ted T. Aoki is an invaluable resource for graduate students, professors, and researchers in curriculum studies, and for students, faculty, and scholars of education generally. (shrink)
The world appears to conscious creatures in terms of experienced sensory qualities, but science doesn't find sensory experience in that world, only physical objects and properties. I argue that the failure to locate consciousness in the world is a function of our necessarily representational relation to reality as knowers: we won't discover the terms in which reality is represented by us in the world as it appears in those terms. Qualia -- arguably a type of representational content -- will therefore (...) not be found in the physical world as characterized in experience or science. Instead, consciousness constitutes a subjective, representational reality for cognitive systems such as ourselves, and the physical world is a represented objective reality. I suggest that naturalistic approaches to explaining consciousness should acknowledge the non-objectivity of experience, and be constrained by evidence that consciousness accompanies certain sorts of behaviour-controlling representational functions carried out by complex, physically instantiated mind-systems. I evaluate a variety of current hypotheses about consciousness, and suggest that a mature science of representation may help explain why, perhaps as matter of representational necessity, experience arises as a natural but not objectively discoverable phenomenon.

Agent-relative consequentialism is thought attractive because it can secure agent-centred constraints while retaining consequentialism's compelling idea—the idea that it is always permissible to bring about the best available outcome. We argue, however, that the commitments of agent-relative consequentialism lead it to run afoul of a plausibility requirement on moral theories. A moral theory must not be such that, in any possible circumstance, were every agent to act impermissibly, each would have more reason to prefer the world thereby actualized over the (...) world that would have been actualized if every agent had instead acted permissibly.

We introduce the notion T does not omit obstructions. If a stable theory does not admit obstructions then it does not have the finite cover property . For any theory T, form a new theory $T_{\rm Aut}$ by adding a new unary function symbol and axioms asserting it is an automorphism. The main result of the paper asserts the following: If T is a stable theory, T does not admit obstructions if and only if $T_{\rm Aut}$ has a model companion. (...) The proof involves some interesting new consequences of the nfcp. (shrink)
Originally published in 1949. This meticulously researched book presents a comprehensive outline and discussion of Aristotle’s mathematics with the author's translations of the greek. To Aristotle, mathematics was one of the three theoretical sciences, the others being theology and the philosophy of nature . Arranged thematically, this book considers his thinking in relation to the other sciences and looks into such specifics as squaring of the circle, syllogism, parallels, incommensurability of the diagonal, angles, universal proof, gnomons, infinity, agelessness of the (...) universe, surface of water, meteorology, metaphysics and mechanics such as levers, rudders, wedges, wheels and inertia. The last few short chapters address ‘problems’ that Aristotle posed but couldn’t answer, related ethics issues and a summary of some short treatises that only briefly touch on mathematics. (shrink)
Can a rule be followed by one person who has lived all his life in as complete isolation from other human beings as is consistent with his mere physical survival? This question divides philosophers as sharply today as it did over thirty years ago when, prompted by their reading of Wittgenstein, they first asked it. My aim here is to suggest a way of reconciling the two opposing sides in the current debate. I also hope to explain why it was (...) that Wittgenstein did not concern himself with the complexities I am about to discuss, which none the less are, I believe, at the root of the difficulties we experience when we try to understand what Wittgenstein said about following a rule and to think clearly about this question.

Various attempts have been made in recent years to present Christianity in such a way that no use is made of the traditional dichotomy between the ‘natural’ and the ‘supernatural’. Braithwaite, Hare, and van Buren, for instance, appear to have no use for the dichotomy; and I think that, without too much distortion, one can say the same of Bultmann, Tillich, and Robinson. I am not, however, concerned in this paper with the work of any one thinker as such, but (...) rather with a general climate of opinion. What I want to do is to examine the grounds on which it might be argued that belief in the supernatural is discredited. The issue seems to me of special importance at the present time, since, if these grounds are inadequate, programmes of reform under the general heading ‘Christianity without the supernatural’lose much of their point; if, on the other hand, the grounds are compelling, then reform of some kind is forced upon us whatever the accompanying difficulties.
