The different interpretations of quark mixing involved in weak interaction processes in the Standard Model and the Generation Model are discussed with a view to obtaining a physical understanding of the Cabibbo angle and related quantities. It is proposed that hadrons are composed of mixed-quark states, with the quark mixing parameters being determined by the Cabibbo-Kobayashi-Maskawa matrix elements. In this model, protons and neutrons contain a contribution of about 5% and 10%, respectively, of strange valency quarks.

A textbook on modal logic, intended for readers already acquainted with the elements of formal logic, containing nearly 500 exercises. Brian F. Chellas provides a systematic introduction to the principal ideas and results in contemporary treatments of modality, including theorems on completeness and decidability. Illustrative chapters focus on deontic logic and conditionality. Modality is a rapidly expanding branch of logic, and familiarity with the subject is now regarded as a necessary part of every philosopher's technical equipment. Chellas here offers (...) an up-to-date and reliable guide essential for the student. (shrink)

Although the body has been the focus of much contemporary cultural theory, the models that are typically applied neglect the most salient characteristics of embodied existence—movement, affect, and sensation—in favor of concepts derived from linguistic theory. In _Parables for the Virtual_ Brian Massumi views the body and media such as television, film, and the Internet, as cultural formations that operate on multiple registers of sensation beyond the reach of the reading techniques founded on the standard rhetorical and semiotic models. (...) Renewing and assessing William James’s radical empiricism and Henri Bergson’s philosophy of perception through the filter of the post-war French philosophy of Deleuze, Guattari, and Foucault, Massumi links a cultural logic of variation to questions of movement, affect, and sensation. If such concepts are as fundamental as signs and significations, he argues, then a new set of theoretical issues appear, and with them potential new paths for the wedding of scientific and cultural theory. Replacing the traditional opposition of literal and figural with new distinctions between stasis and motion and between actual and virtual, _Parables for the Virtual _tackles related theoretical issues by applying them to cultural mediums as diverse as architecture, body art, the digital art of Stelarc, and Ronald Reagan’s acting career. The result is an intriguing combination of cultural theory, science, and philosophy that asserts itself in a crystalline and multi-faceted argument. _Parables for the Virtual_ will interest students and scholars of continental and Anglo-American philosophy, cultural studies, cognitive science, electronic art, digital culture, and chaos theory, as well as those concerned with the “science wars” and the relation between the humanities and the sciences in general.

When making substituted judgments for incapacitated patients, surrogates often struggle to guess what the patient would want if they had capacity. Surrogates may also agonize over having the (sole) responsibility of making such a determination. To address such concerns, a Patient Preference Predictor (PPP) has been proposed that would use an algorithm to infer the treatment preferences of individual patients from population-level data about the known preferences of people with similar demographic characteristics. However, critics have suggested that even if such (...) a PPP were more accurate, on average, than human surrogates in identifying patient preferences, the proposed algorithm would nevertheless fail to respect the patient’s (former) autonomy since it draws on the ‘wrong’ kind of data: namely, data that are not specific to the individual patient and which therefore may not reflect their actual values, or their reasons for having the preferences they do. Taking such criticisms on board, we here propose a new approach: the Personalized Patient Preference Predictor (P4). The P4 is based on recent advances in machine learning, which allow technologies including large language models to be more cheaply and efficiently ‘fine-tuned’ on person-specific data. The P4, unlike the PPP, would be able to infer an individual patient’s preferences from material (e.g., prior treatment decisions) that is in fact specific to them. Thus, we argue, in addition to being potentially more accurate at the individual level than the previously proposed PPP, the predictions of a P4 would also more directly reflect each patient’s own reasons and values. In this article, we review recent discoveries in artificial intelligence research that suggest a P4 is technically feasible, and argue that, if it is developed and appropriately deployed, it should assuage some of the main autonomy-based concerns of critics of the original PPP. We then consider various objections to our proposal and offer some tentative replies. (shrink)

Gossip is often serious business, not idle chitchat. Gossip allows those oppressed to privately name their oppressors as a warning to others. Of course, gossip can be in error. The speaker may be lying or merely have lacked sufficient evidence. Bias can also make those who hear the gossip more or less likely to believe the gossip. By examining the social functions of gossip and considering the differences in power dynamics in which gossip can occur, we contend that gossip may (...) be not only permissible but virtuous, both as the only reasonable recourse available and as a means of resistance against oppression.

More and more people would like to migrate, but find that every state places barriers in their way. At the same time, most governments not only permit but court foreign investment. Can this difference between the treatment of people and the treatment of money be justified? This book asks this question from the point of view of five different ethical perspectives: liberal egalitarianism, libertarianism, Marxism, natural law and political realism. -- FROM BOOK JACKET.

In _What Animals Teach Us about Politics_, Brian Massumi takes up the question of "the animal." By treating the human as animal, he develops a concept of an animal politics. His is not a human politics of the animal, but an integrally animal politics, freed from connotations of the "primitive" state of nature and the accompanying presuppositions about instinct permeating modern thought. Massumi integrates notions marginalized by the dominant currents in evolutionary biology, animal behavior, and philosophy—notions such as play, (...) sympathy, and creativity—into the concept of nature. As he does so, his inquiry necessarily expands, encompassing not only animal behavior but also animal thought and its distance from, or proximity to, those capacities over which human animals claim a monopoly: language and reflexive consciousness. For Massumi, humans and animals exist on a continuum. Understanding that continuum, while accounting for difference, requires a new logic of "mutual inclusion." Massumi finds the conceptual resources for this logic in the work of thinkers including Gregory Bateson, Henri Bergson, Gilbert Simondon, and Raymond Ruyer. This concise book intervenes in Deleuze studies, posthumanism, and animal studies, as well as areas of study as wide-ranging as affect theory, aesthetics, embodied cognition, political theory, process philosophy, the theory of play, and the thought of Alfred North Whitehead.

It is frequently claimed that we can learn very little, if anything, about the aesthetic character of an artwork on the basis of testimony. Such disparaging assessments of the epistemic value of aesthetic testimony contrast markedly with our acceptance of testimony as an important source of knowledge in many other areas. There have, however, been a number of challenges to this orthodoxy of late; from those who seek to deny that such a contrast exists as well as attempts by those (...) who accept the distinction to provide an explanation and defence of the contrast. In Section I, I outline a little of the nature and history of the debate over aesthetic testimony. Section II, focuses on the opposing positions on aesthetic testimony, optimism and pessimism, and takes steps to clarify what exactly is at issue between them. In Section III, I survey considerations which have been adduced in favour of pessimism ranging from brute appeal to intuition to complex argumentation before turning in Section IV, to look at motivations for optimism. Finally, in Section V, I consider some alternative views which claim that, for a variety of reasons, it is a mistake to construe the debate over aesthetic testimony as concerned with the epistemic standing of aesthetic beliefs formed on the basis of testimony.

Color coded terror alerts, invasion, drone war, rampant surveillance: all manifestations of the type of new power Brian Massumi theorizes in _Ontopower_. Through an in-depth examination of the War on Terror and the culture of crisis, Massumi identifies the emergence of preemption, which he characterizes as the operative logic of our time. Security threats, regardless of the existence of credible intelligence, are now felt into reality. Whereas nations once waited for a clear and present danger to emerge before using (...) force, a threat's felt reality now demands launching a preemptive strike. Power refocuses on what _may_ emerge, as that potential presents itself to feeling. This affective logic of potential washes back from the war front to become the dominant mode of power on the home front as well. This is ontopower—the mode of power embodying the logic of preemption across the full spectrum of force, from the “hard” to the "soft". With _Ontopower_, Massumi provides an original theory of power that explains not only current practices of war but the culture of insecurity permeating our contemporary neoliberal condition.

The nature of measurement is a topic of central concern in the philosophy of science and, indeed, measurement is the essential link between science and mathematics. Professor Ellis's book, originally published in 1966, is the first general exposition of the philosophical and logical principles involved in measurement since N. R. Campbell's Principles of Measurement and Calculation, and P. W. Bridgman's Dimensional Analysis. Professor Ellis writes from an empiricist standpoint. His object is to distinguish and define the basic concepts in measurement, (...) for example: scale, quantity, unit. dimension, number and probability. He discusses the problem of classifying scales of measurement and the special logical problems associated with each kind of scale. A translation of mach's Critique on the Concept of Temperature, which gives his views on the nature of measurement more fully than in any of his other works, is given as an appendix. (shrink)

How do we form aesthetic judgements? And how should we do so? According to a very prominent tradition in aesthetics it would be wrong to form our aesthetic judgements about a particular object on the basis of anything other than first-hand acquaintance with the object itself (or some very close surrogate) and, in particular, it would be wrong to form such judgements merely on the basis of testimony. Further this tradition presupposes that our actual practice of forming aesthetic judgements typically (...) meets, or at least approximates, this ideal. In this paper I target this descriptive claim and argue—by appeal to some empirical work concerning belief polarization and echo chambers in aesthetics—that our actual practice of forming aesthetic judgements is heavily dependent on social sources such as testimony. I then briefly consider what normative implications this descriptive claim may have. (shrink)

A common view among nontheists combines the de jure objection that theism is epistemically unacceptable with agnosticism about the de facto objection that theism is false. Following Plantinga, we can call this a “proper” de jure objection—a de jure objection that does not depend on any de facto objection. In his Warranted Christian Belief, Plantinga has produced a general argument against all proper de jure objections. Here I first show that this argument is logically fallacious (it makes subtle probabilistic fallacies (...) disguised by scope ambiguities), and proceed to lay the groundwork for the construction of actual proper de jure objections.

Unusability pessimism has recently emerged as an appealing new option for pessimists about aesthetic testimony—those who deny the legitimacy of forming aesthetic beliefs on the basis of testimony. Unusability pessimists argue that we should reject the traditional pessimistic stance that knowledge of aesthetic matters is unavailable via testimony in favour of the view that while such knowledge is available to us, it is unusable. This unusability stems from the fact that accepting such testimony would violate an important non-epistemic norm of (...) belief formation. In this article I present an objection to unusability pessimism and argue that Robert Hopkins, the view's most prominent defender, fails to motivate adequately the claim that there are such non-epistemic belief norms. The cases which putatively legitimize usability norms can be explained by appeal to more familiar norm types: epistemic norms of belief formation, and non-epistemic norms which govern action other than belief formation. The intent of this article is not primarily negative, however, and I will also argue that understanding why the unusability position fails helps us to identify a promising new direction for the pessimist's opponents who wish to defend the legitimacy of forming aesthetic beliefs on the basis of testimony.

The central thesis of this paper is that fake news and related phenomena serve as defeaters for knowledge transmission via journalistic channels. This explains how they pose a threat to democracy; and it points the way to determining how to address this threat. Democracy is both intrinsically and instrumentally good provided the electorate has knowledge (however partial and distributed) of the common good and the means of achieving it. Since journalism provides such knowledge, those who value democracy have a reason (...) to protect it. Hostile agents, however, can undermine both the effectiveness of democratic decision-making and faith in democracy itself, by deliberately promulgating fake news and hyper-partisan views; moreover, these effects can come about unintentionally on social media. I conclude that we may need to change, not just the way we process information online, but also the informational environment in which we operate. (shrink)

Safety-based theories of knowledge face a difficulty surrounding necessary truths: no subject could have easily falsely believed such a proposition. Failing to predict that ill-grounded beliefs in such propositions do not constitute knowledge, standard safety theories are therefore less informative than desired. Some have suggested that the subjects at issue could easily have believed some related false proposition; but they have given no indication as to what makes a proposition related. I suggest a solution to this problem: a belief is (...) safe iff its subject could not easily have believed a false answer to the same question. (shrink)

Events are always passing; to experience an event is to experience the passing. But how do we perceive an experience that encompasses the just-was and the is-about-to-be as much as what is actually present? In _Semblance and Event_, Brian Massumi, drawing on the work of William James, Alfred North Whitehead, Gilles Deleuze, and others, develops the concept of "semblance" as a way to approach this question. It is, he argues, a question of abstraction, not as the opposite of the (...) concrete but as a dimension of it: "lived abstraction." A semblance is a lived abstraction. Massumi uses the category of the semblance to investigate practices of art that are relational and event-oriented -- variously known as interactive art, ephemeral art, performance art, art intervention -- which he refers to collectively as the "occurrent arts." Each art practice invents its own kinds of relational events of lived abstraction, to produce a signature species of semblance. The artwork's relational engagement, Massumi continues, gives it a political valence just as necessary and immediate as the aesthetic dimension. (shrink)

What is the relationship between acquaintance and aesthetic judgement? Wollheim’s acquaintance principle (AP) is one answer. Amir Konigsberg—the most recent critic of AP—has produced a number of examples which he claims will require us to restrict AP even further than has previously been suggested. I argue that Konigsberg is mistaken and that his examples do not necessitate any further restrictions on AP. This failure, however, is not the result of some specific flaw in Konigsberg’s argument; rather it is an artefact (...) of a deeper problem at the heart of the current debate over AP (and its successors). I conclude by arguing that this problem—the absence of any satisfactory reformulation of AP itself—has far-reaching consequences for our theorizing in aesthetics. (shrink)

When we say that what two people feel for each other is 'true love,' we seem to be doing more than simply clarifying that it is in fact love they feel, as opposed to something else. That is, an experience or relationship might be a genuine or actual instance of love without necessarily being an instance of true love. But what criteria do people use to determine whether something counts as true love? This chapter explores three hypotheses. The first holds (...) that the ordinary concept of true love picks out love that is highly prototypical. The second, that it picks out love that is especially good or valuable. The third, that people distinguish between psychological states that are 'real' or not, and that it picks out love that is real. Two experiments provide evidence against the first hypothesis and in favor of the second and third. Implications for real-life disagreements about love are also discussed. (shrink)

This paper responds to a problem, raised by Martinez, for Millikan’s explanation of the interpretability of novel signs in terms of mapping functions. I argue that Martinez’s critique is a logically weakened version of Kripke’s skeptical argument about rule following. Responding to Martinez requires two things. First, we must correctly understand the role of simplicity and elegance in choosing the correct mapping function for a signaling system. Second, we need to understand that mapping functions are descriptions of the features that (...) determine the content of signs; they do not themselves determine the content of signs. Bearing these facts in mind, Martinez’s concern is assuaged. However, we find that this position on the role of mapping functions is not fully consistent with Millikan’s response to Kripke. I modify her response to Kripke and demonstrate that the alterations do not undermine her view. (shrink)

Ontologies formally represent reality in a way that limits ambiguity and facilitates automated reasoning and data fusion, but is often daunting to the non-technical user. Thus, many researchers have endeavored to hide the formal syntax and semantics of ontologies behind the constructs of Controlled Natural Languages (CNLs), which retain the formal properties of ontologies while simultaneously presenting that information in a comprehensible natural language format. In this paper, we build upon previous work in this field by evaluating prospects of implementing (...) International Technology Alliance Controlled English (ITACE) as a middleware for ontology editing. We also discuss at length a prototype of a natural language conversational interface application designed to facilitate ontology editing via the formulation of CNL constructs. (shrink)

Rational self-interest is often seen as being at the heart of liberal economic theory. In _The Power at the End of the Economy_ Brian Massumi provides an alternative explanation, arguing that neoliberalism is grounded in complex interactions between the rational and the emotional. Offering a new theory of political economy that refuses the liberal prioritization of individual choice, Massumi emphasizes the means through which an individual’s affective tendencies resonate with those of others on infra-individual and transindividual levels. This nonconscious (...) dimension of social and political events plays out in ways that defy the traditional equation between affect and the irrational. Massumi uses the Arab Spring and the Occupy Movement as examples to show how transformative action that exceeds self-interest takes place. Drawing from David Hume, Michel Foucault, Gilles Deleuze, Niklas Luhmann and the field of nonconsciousness studies, Massumi urges a rethinking of the relationship between rational choice and affect, arguing for a reassessment of the role of sympathy in political and economic affairs.

The foundational principles of representative democracy are under attack globally. What we desperately need are enlightened and persuasive public intellectuals who can help us see through the fog of our fear, anger, and disillusionment, to find our rational political commitments again. One of these public intellectuals is undoubtedly Yuval Noah Harari, the bestselling author of three recent books – Sapiens, Homo Deus, and 21 Lessons for the 21st Century. Harari is also a frequent contributor in the popular press, and a (...) guest on shows, podcasts, panels, and as a keynote speaker. Add to all this that Harari is acting on his lofty academic ideals through ‘Sapienship’, a multidisciplinary organization he cofounded that advocates for global responsibility, clarifies the global conversation, and focuses attention on the most important global challenges. I single out Harari because I presume many readers will be familiar with his work. He is certainly one of the fastest rising stars of public intellectualism. Unfortunately, his work is undercut by the philosophical positions he put forth in his first bestselling book, Sapiens. In this review/critique I wish to show that in order for Harari advance a coherent political or ideological argument, he must first shore up his philosophical commitments. (shrink)

In _Couplets_, Brian Massumi presents twenty-four essays that represent the full spectrum of his work during the past thirty years. Conceived as a companion volume to _Parables for the Virtual_, _Couplets_ addresses the key concepts of _Parables_ from different angles and contextualizes them, allowing their stakes to be more fully felt. Rather than organizing the essays chronologically or by topic, Massumi pairs them into couplets to encourage readers to make connections across conventional subject matter categories, to encounter disjunctions, and (...) to link different phases in the evolution of his work. In his analyses of topics ranging from art, affect, and architecture to media theory, political theory, and the philosophy of experience, Massumi charts a field on which a family of conceptual problems plays out in ways that bear on the potentials for acting and perceiving the world. As an essential guide to Massumi's oeuvre, _Couplets_ is both a primer for his new readers and a supplemental resource for those already engaged with his thought. (shrink)

There is growing consensus that reward plays an important role in the control of attention. Until recently, reward was thought to influence attention indirectly by modulating task-specific motivation and its effects on voluntary control over selection. Such an account was consistent with the goal-directed (endogenous) versus stimulus-driven (exogenous) framework that had long dominated the field of attention research. Now, a different perspective is emerging. Demonstrations that previously reward-associated stimuli can automatically capture attention even when physically inconspicuous and task-irrelevant challenge previously (...) held assumptions about attentional control. The idea that attentional selection can be value driven, reflecting a distinct and previously unrecognized control mechanism, has gained traction. Since these early demonstrations, the influence of reward learning on attention has rapidly become an area of intense investigation, sparking many new insights. The result is an emerging picture of how the reward system of the brain automatically biases information processing. Here, I review the progress that has been made in this area, synthesizing a wealth of recent evidence to provide an integrated, up-to-date account of value-driven attention and some of its broader implications.

Since the publication of Ruth Millikan's Language, Thought, and Other Biological Categories in 1984, a great deal of literature has discussed her so-called teleosemantic or biosemantic solution to the problem of intentionality. Only recently, though, has much attention been paid to her co-ordinated solution to the problem of productivity. This article, first, clearly describes the problems of intentionality, productivity, and compositionality, and describes their relationships and their relevance for the theory of meaning. It then describes Millikan's proposal with respect to (...) the problem of intentionality and shows how this buys her a novel solution to the problem of productivity. The article closes by discussing some alternative teleosemantic theories and some issues that will contribute to deciding between them. (shrink)

Even for one, individual, singular person, there are potential problelms with Utilitarianism. We must decide whether we go for pleasure, or try to avoid pain. Many other options are available. In addition to maximizing pleasure, we must also think of what the probabilistic likelihood to getting what we want. When weunderstand the problems, we also face the problem of making transitive decisions. Problems with Intransitive decisions take us out of Utilitarian theory. When we add additional people, the problems are still (...) there, but are now elevated. We see there are exact contradictions, and when we add the problems of evaluating,utilitarianism is more difficult than we had expected. Even Jeremy Bentham’s approach leaves us with problems that cut every way in different directions. This is only a start for Utilitarianism. (shrink)

It is necessarily true that water is H2O, but it is a contingent fact that there is any water at all. Water therefore seems ill suited to ground the necessary truth that water is H2O. One view traditionally attributed to Scotus and Henry of Ghent was that while water is contingent, the essence of water is necessary; hence, the essence of water can ground the so-called eternal truth that water is H2O. Francisco Suárez rejects this view on the grounds that (...) it contradicts the Christian doctrine of creation, according to which everything other than God was contingently created in time. Suárez’s own view of the eternal truths has proven elusive to commentators, but I argue that Suárez ultimately endorses a version of the view he rejects: essences ground the eternal truths. But this raises several puzzles: how is Suárez’s view distinct from the views traditionally ascribed to Scotus and Henry? How does Suárez’s view escape the argument from creation, which Suárez raises against his opponents? I argue that Suárez distinguishes between his view and his opponents’ view by saying that essences have “extrinsic being,” whereas his opponents claim that essences have “intrinsic being.” The distinction between intrinsic and extrinsic being has not received much attention, but I argue that it marks an important fault line in scholastic thinking about the ontological status of non-existents. I argue that the notion of extrinsic being can be explicated in terms of ontological pluralism and grounding. The notion of extrinsic being helps differentiate Suárez’s view from his Scotistic and Henrician opponents, and it allows Suárez to respond to the creation argument he raises against his opponents. On my reading, Suárez’s solution to the problem of eternal truths turns out to be both highly original and philosophically satisfying. (shrink)

In this paper I explore the relationship between the idea of possible worlds and the notion of the beauty of God. I argue that there is a clear contradiction between the idea that God is utterly and completely beautiful on the one hand and the notion that He contains within himself all possible worlds on the other. Since some of the possible worlds residing in the mind of the deity are ugly, their presence seems to compromise God's complete and utter (...) beauty. (shrink)
