RAID-II is a high-bandwidth, network-attached storage server designed and implemented at the University of California at Berkeley. In this paper, we measure the performance of RAID-II and evaluate various architectural decisions made during the design process. We first measure the end-to-end performance of the system to be approximately 20 MB/s for both disk array reads and writes. We then perform a bottleneck analysis by examining the performance of each individual subsystem and conclude that the disk subsystem limits performance. By adding (...) a custom interconnect board with a high-speed memory and bus system and parity engine, we are able to achieve a performance speedup of 8 to 15 over a comparative system using only off-the-shelf hardware.

Comparative Political Theory and Cross-Cultural Philosophy explores new forms of philosophizing in the age of globalization by challenging the conventional border between the East and the West, as well as the traditional boundaries among different academic disciplines. This rich investigation demonstrates the importance of cross-cultural thinking in our reading of philosophical texts and explores how cross-cultural thinking transforms our understanding of the traditional philosophical paradigm.

The precise orchestration of two opposing protein complexes – one in the cytoplasm (β‐catenin destruction complex) and the other at the plasma membrane (LRP6 signaling complex) – is critical for controlling levels of the transcriptional co‐factor β‐catenin, and subsequent activation of the Wnt/β‐catenin signal transduction pathway. The Wnt pathway component Axin acts as an essential scaffold for the assembly of both complexes. How the β‐catenin destruction and LRP6 signaling complexes are modulated following Wnt stimulation remains controversial. A recent study in (...) Science by He and coworkers reveals an underlying logic for Wnt pathway control in which Axin phosphorylation toggles a switch between the active and inactive states. This mini‐review focuses on this and two other recent studies that provide insight into the initial signaling events triggered by Wnt exposure. We emphasize regulation of the β‐catenin destruction and LRP6 signaling complexes and propose a framework for future work in this area. (shrink)

In How to Talk to a Science Denier, Lee McIntyre tells the story of his own adventures in talking face to face with science deniers and their victims-including a Flat Earth convention in Denver, coal miners in rural Pennsylvania, and fishermen in the Maldives-and what he learned from the experience.

Conventional wisdom has it that truth is always evaluated using our actual linguistic conventions, even when considering counterfactual scenarios in which different conventions are adopted. This principle has been invoked in a number of philosophical arguments, including Kripke’s defense of the necessity of identity and Lewy’s objection to modal conventionalism. But it is false. It fails in the presence of what Einheuser (2006) calls c-monsters, or convention-shifting expressions (on analogy with Kaplan’s monsters, or context-shifting expressions). We show that c-monsters naturally (...) arise in contexts, such as metalinguistic negotiations, where speakers entertain alternative conventions. We develop an expressivist theory—inspired by Barker (2002) and MacFarlane (2016) on vague predications and Einheuser (2006) on counterconventionals—to model these shifts in convention. Using this framework, we reassess the philosophical arguments that invoked the conventional wisdom. (shrink)

We develop and defend a new approach to counterlogicals. Non-vacuous counterlogicals, we argue, fall within a broader class of counterfactuals known as counterconventionals. Existing semantics for counterconventionals, 459–482 ) and, 1–27 ) allow counterfactuals to shift the interpretation of predicates and relations. We extend these theories to counterlogicals by allowing counterfactuals to shift the interpretation of logical vocabulary. This yields an elegant semantics for counterlogicals that avoids problems with the usual impossible worlds semantics. We conclude by showing how this approach (...) can be extended to counterpossibles more generally. (shrink)

A thought-provoking comparative take on two seminal thinkers in Christian history In this book -- the first volume in the Kierkegaard as a Christian Thinker series -- Lee Barrett offers a novel comparative interpretation of early church father Augustine and nineteenth-century philosopher-theologian Soren Kierkegaard. Though these two intellectual giants have been paired by historians of Western culture, the exact nature of their similarities and differences has never before been probed in detail. Barrett demonstrates that on many essential theological levels Augustine (...) and Kierkegaard were more convergent than divergent. Most significantly, their parallels point to a distinctive understanding of the Christian life as a passion for self-giving love. Approaching Kierkegaard through the lens of Augustine, Barrett argues, enables the theme of desire for fulfillment in God to be seen as much more central to Kierkegaard's thought than previously imagined.

Both Watts and Beit-Hallahmi are enthusiastic about attachment theory as an important contribution to the psychology of religion, but they raise very different criticisms regarding other aspects of the book. I respond to Beit-Hallahmi by defending my assertion that a scientific approach to psychology of religion need not lead to the conclusion, nor rest on the premise, that the beliefs under study are ontologically false. I argue further that this "veridicality trap" has deep roots in prevailing, deeply mistaken assumptions about (...) how the mind/brain works, and show how an evolutionary approach clearly exposes such reasoning as fallacious and offers a powerful, alternative perspective on the problem. In response to Watts, I defend evolutionary psychology against the charge that it is not sufficiently empirical, and argue that the computational cognitive approach he prefers should be seen as complementary to an evolutionary approach rather than an alternative to it.

Cool Characters tells the story of American political irony from World War II to the present: how irony came to seem politically subversive for American countercultural rebels; how mainstream culture allegedly co-opted countercultural irony; how irony became part of major critical theories of postmodernism; and how -- starting in the late 1980s -- innovative writers developed an idea of "postirony" with the hope of overcoming the political limitations of postmodern irony. To chart the shift from irony to postirony, and show (...) what relationship culture has to politics, the book offers intensive analyses of important American countercultural figures: the hipster, the punk, a figure the author calls "the believer," the coolhunter, and the occupier; and new interpretations of important works by Ralph Ellison, Thomas Pynchon, William S. Burroughs, Kathy Acker, Michael Muhammad Knight, David Foster Wallace, Dave Eggers, Alex Shakar, William Gibson, Jennifer Egan, Jonathan Lethem, and Rachel Kushner."--Provided by publisher. (shrink)

Popper Proposed the criterion of falsifiability as a solution to the problem of demarcation i.e. of distinguishing science from pseudo-science and not, as many of his contemporaries in the Vienna Circle mistook it to be, a solution to the quite different problem with which they themselves were preoccupied, viz. of providing a criterion of meaning to distinguish the meaningful from the meaningless. While the positivists were concerned to damn metaphysics and exalt science, by identifying the empirically verifiable with the meaningful, (...) Popper was concerned to separate science from scientism, to damn astrology and to extol astronomy. In other words his preoccupation belongs not to the philosophy of language but to the philosophy of science. (shrink)

A concern central to virtually all full-blooded instances of religious ethics is how persuasively to represent a world central to our fulfillment that far exceeds our normal understanding. The treatment of three kinds of language in an early Daoist text, the Zhuangzi (Chuang Tzu), contains an especially profound discussion and expression of such persuasive presentations in religious ethics. This study examines it and concludes by viewing Dante's Commedia through the perspectives Zhuangzi's ideas and practices present.

ABSTRACTIn the Timaeus, Plato explicitly defines time as “the moving image of eternity”. This proposition affirms actually that time reflects the eternal that embodies the rational and lawful principle – namely the logos of proportionality – in the motion and change of visible objects in the universe. In other words,time determines the principle that every mutable being must follow to participate in the rational and nomological order of existence; the absolute logos which is given by God is hence intrinsic to (...) time. This idea of time is echoed by the theories of Augustine and Husserl. Both philosophers inherited some of Plato’s metaphysical views, and each of them developed a distinctive theory of the relations between Being, time, and the absolute logos. This paper attempts to compare their theories and to defend the following claim: Augustine fo-cuses on the immutable representation of time which is regarded as the image or reflection of God’s absolute logos, and explains temporal phenome...

In the following essay, I argue for an alternative anthropocentrism that, eschewing failed appeals to traditional moral principle, takes (a) as its point of departure the cognitive, perceptual, emotive, somatic, and epistemic conditions of our existence as members of Homo sapiens, and (b) one feature of our experience of/under these conditions particularly seriously as an avenue toward articulating this alternative, the capacity for aesthetic appreciation. To this end, I will explore, but ultimately reject philosopher Allen Carlson's ecological aesthetics, and I (...) will adopt with modification aspects of the work of Ronnie Hawkins, Val Plumwood, and Donna Haraway. My central claim is that, equipped with a better understanding of our interdependent relationship to/within human and nonhuman nature, an understanding made especially available to those who occupy situations imbued by subjugation, we can come to understand our human-centeredness not as a justification of entitlement, but as an opportunity for critical self-reflection upon those actions which endanger the ecological conditions of human and nonhuman being. I suggest, then, that developing criteria for an aesthetic appreciation ground in such a centeredness can make a vital contribution to a more ecologically defensible moral and political activism.

We examined the question—is the intention of completing a simulated motor action the same as the intention used in processing overt actions? Participants used motor imagery to estimate distance reachability in two conditions: Imagery-Only and Imagery-Execution . With IO only a verbal estimate using imagery was given. With IE participants knew that they would actually reach after giving a verbal estimate and be judged on accuracy. After measuring actual maximum reach, used for the comparison, imagery targets were randomly presented across (...) peripersonal- and extrapersonal space. Results indicated no difference in overall accuracy by condition, however, there was a significant distinction by space; participants were more accurate in peripersonal space. Although more research is needed, these findings support an increasing body of evidence suggesting that the neurocognitive processes driving motor imagery and overt actions are similar. (shrink)

Moral luck, until recently, has been understood either explicitly or implicitly through using a lack of control account of luck. For example, a case of resultant moral luck is a case where an agent is morally blameworthy or more morally blameworthy or praiseworthy for an outcome despite that outcome being significantly beyond that agent's control (Nagel ). Due to a shift in understanding the concept of luck itself in terms of modal robustness, however, other accounts of moral luck have surfaced. (...) Both Duncan Pritchard () and Julia Driver () have offered an alternative way of understanding moral luck by employing versions of a modal account of luck. This essay considers some problems with these accounts and attempts to resolve them. (shrink)

This paper deals with the semantics and meta-semantics for ordinary names in fiction. It has recently been argued by some philosophers that when ordinary names are used in fictional contexts, they change their semantic contents and work as fictional names in general. In this paper, I argue that there is no compelling reason to believe that such reference changes occur and defend the view that whether those names refer to real or fictional objects depends on which semantic intentions speakers have.

Long awaited after No Future, and making queer theory controversial again, Lee Edelman's Bad Education proposes a queerness without positive identity-a queerness understood as a figural name for the void, itself unnamable, around which the social order takes shape. Like Blackness, woman, incest, and sex, queerness, as Edelman explains it, designates the antagonism, the structuring negativity, preventing that order from achieving coherence. But when certain types of persons get read as literalizing queerness, the negation of their negativity can seem to (...) resolve the social antagonism and totalize community. By translating the nothing of queerness into the something of "the queer," the order of meaning defends against the senselessness that undoes it, thus mirroring, Edelman argues, education's response to queerness: its sublimation of irony into the meaningfulness of a world. Putting queerness in relation to Lacan's "ab-sens" and in dialogue with feminist and Afropessimist thought, Edelman reads works by Shakespeare, Jacobs, Almodovar, Lemmons, and Haneke, among others, to show why queer theory's engagement with queerness necessarily results in a bad education that is destined to teach us nothing.

For more than a century, scholars have believed that Italian humanism was predominantly civic in outlook. Often serving in communal government, fourteenth-century humanists like Albertino Mussato and Coluccio Saltuati are said to have derived from their reading of the Latin classics a rhetoric of republican liberty that was opposed to the "tyranny" of neighbouring signori and of the German emperors. In this ground-breaking study, Alexander Lee challenges this long-held belief. From the death of Frederick II in 1250 to the failure (...) of Rupert of the Palatinate's ill-fated expedition in 1402, Lee argues, the humanists nurtured a consistent and powerful affection for the Holy Roman Empire. Though this was articulated in a variety of different ways, it was nevertheless driven more by political conviction than by cultural concerns. Surrounded by endless conflict--both within and between city-states--the humanists eagerly embraced the Empire as the surest guarantee of peace and liberty, and lost no opportunity to invoke its protection. Indeed, as Lee shows, the most ardent appeals to imperial authority were made not by "signorial" humanists, but by humanists in the service of communal regimes. The first comprehensive, synoptic study of humanistic ideas of Empire in the period c.1250-1402, this volume offers a radically new interpretation of fourteenth-century political thought, and raises wide-ranging questions about the foundations of modern constitutional ideas. As such, it is essential reading not just for students of Renaissance Italy and the history of political thought, but for all those interested in understanding the origins of liberty. (shrink)

Our topic is the ontology and persistence conditions of material objects. One widely held doctrine is that identity-over-time has causal commitments. Another is that identity-over-time is just identity as it relates one object that exists at two times. We believe that a tension exists between these two apparently sensible positions: very roughly, if identity is the primary conceptual component of identity-over-time and—as is plausible—identity is noncausal, then the conceptual origins of the causal commitments of identity-over-time become a mystery. We will (...) begin by formulating the two widely held doctrines and our puzzle more fully and more carefully. Then, the remainder of the paper will be devoted to analyzing views one might adopt that could minimize the tension. (shrink)

Source code is a form of human communication, albeit one where the information shared between the programmers reading and writing the code is constrained by the requirement that the code executes correctly. Programming languages are more syntactically constrained than natural languages, but they are also very expressive, allowing a great many different ways to express even very simple computations. Still, code written by developers is highly predictable, and many programming tools have taken advantage of this phenomenon, relying on language model (...) surprisal as a guiding mechanism. While surprisal has been validated as a measure of cognitive load in natural language, its relation to human cognitive processes in code is still poorly understood. In this paper, we explore the relationship between surprisal and programmer preference at a small granularity—do programmers prefer more predictable expressions in code? Using meaning‐preserving transformations, we produce equivalent alternatives to developer‐written code expressions and run a corpus study on Java and Python projects. In general, language models rate the code expressions developers choose to write as more predictable than these transformed alternatives. Then, we perform two human subject studies asking participants to choose between two equivalent snippets of Java code with different surprisal scores (one original and transformed). We find that programmers do prefer more predictable variants, and that stronger language models like the transformer align more often and more consistently with these preferences. (shrink)

Teaching the nuances of ethical decision making is particularly challenging in fully online, asynchronous courses where real-time discussion is not an option. Digital simulations, in the context of an integrative online ethics course, can offer applied learning and assessment experiences. However, scholarship on the impact of digital simulations for teaching ethical decision making is limited. The purpose of this study is to explore whether digital simulation used as an assessment for ethical reasoning and complex decision making is effective in helping (...) business students heighten their awareness of values in tension and discern ethical paths to resolution. We conduct an exploratory analysis of two ethics simulations used in teaching nine graduate business ethics classes offered in an asynchronous, online format. We discuss the results in terms of the Markkula Center for Applied Ethics’ five-step ethical decision making framework and outline implications for teaching and future research on business ethics simulations.

Unlike natural agents, artificial agents are, to varying extent, designed according to sets of principles or assumptions. We argue that the designer’s philosophical position on truth, belief and knowledge has far reaching implications for the design and performance of the resulting agents. Of the many sources of design information and background we believe philosophical theories are under-rated as valuable influences on the design process. To explore this idea we have implemented some computer-based agents with their control algorithms inspired by two (...) strongly contrasting philosophical positions. A series of experiments on these agents shows that, despite having common tasks and goals, the behaviour of the agents is markedly different and this can be attributed to their individual approaches to belief and knowledge. We discuss these findings and their support for the view that epistemological theories have a particular relevance for artificial agent design. (shrink)

Without doubt, Weighing Lives, like its precursor, Weighing Goods, is an excellent and thought-provoking piece of work. In the first place, it addresses a question of the most fundamental importance, namely: how should we aggregate the well-being of past, present and future members of the human race under the various possible states of the world that may, in the event, prevail? This involves, amongst other things, dealing with questions of aggregation across time, people and different states of the world; the (...) issue of what constitutes a “neutral” state of well-being and what is, in fact, the value of continuing to survive.

In polite contexts, people find it difficult to perceive whether they can derive scalar inferences from what others say . Because this uncertainty can lead to costly misunderstandings, it is important to identify the cues people can rely on to solve their interpretative problem. In this article, we consider two such cues: Making a long Pause before the statement, and prefacing the statement with Well. Data from eight experiments show that Pauses are more effective than Wells as cues to scalar (...) inferences in polite contexts—because they appear to give a specific signal to switch expectations in the direction of bad news, whereas Well appears to give a generic signal to make extra processing effort. We consider the applied value of these findings for human–human and human–machine interaction, as well as their implications for the study of reasoning and discourse. (shrink)

What are the prospects for a linguistic approach to ontology? Given that it seems that there are true subject-predicate sentences containing empty names, traditional linguistic approaches to ontology appear to be flawed. I argue that in order to determine what there is, we need to determine which sentences ascribe properties (and relations) to objects, and that there does not appear to be any formal criterion for this. This view is then committed to giving an account of what predicates do in (...) sentences when they do not ascribe properties. I sketch an approach to the varieties of predication. (shrink)

I defend Kant’s moral psychology against John R. Silber’s argument that Kant cannot account for the radical evil of Hitler. Silber’s argument cannot be maintained, I argue, if Kant’s account of theological and moral fanaticism, and the personality of the moral fanatic, are taken into account. I contend that Kant’s writings support an analogy between the fanatical pursuit of religious and moral ideals and Hitler’s fanatical pursuit of an ideal of racial purity. I conclude that Kant’s account of moral fanaticism (...) is adequate to account for the actions and moral psychology of Hitler. (shrink)

It is well known that Hume gave a powerful skeptical argument against induction. Many philosophers think that even though Hume’s description of induction is inadequate in some respects, his skeptical argument is still irrefutable. However, Okasha argues that this cannot be right: Once we adequately describe what we are doing with induction, Hume’s skeptical argument cannot be applied to this adequate description of induction any more. In this paper, in opposition to Okasha, I will argue that Hume’s skeptical argument still (...) can be applied even on the ‘adequate’ description of induction. (shrink)
