Eating Goldstone Bosons in a Phase Transition: A Critical Review of Lyre’s Analysis of the Higgs Mechanism

In this note, I briefly review Lyre’s (2008) analysis and interpretation of the Higgs mechanism. Contrary to Lyre, I maintain that, on the proper understanding of the term, the Higgs mechanism refers to a physical process in the course of which gauge bosons acquire a mass. Since also Lyre’s worries about imaginary masses can be dismissed, a realistic interpretation of the Higgs mechanism seems viable. While it may remain an open empirical question whether the Higgs mechanism did actually occur in the early history of the universe and what the details of the mechanism are, I claim that the term can certainly refer to a physical process.     

What Do Powers Do When They Are Not Manifested?*

In the present paper, I offer a conceptual argument against the view that all properties are pure powers. I claim that thinking of all properties as pure powers leads to a regress. The regress, I argue, can be solved only if non‐powers are admitted. The kernel of my thesis is that any attempt to answer the title question in an informative way will undermine a pure‐power view of properties. In particular, I focus my critique on recent arguments in favour of pure powers by the Late George Molnar and Jennifer McKitrick. The lines of defence of the friends of powers converge on what I call ‘the ultimate argument for powers’, viz., that current physics entails (or supports) the view that the fundamental properties (spin, mass, charge) are ungrounded powers. I take issue with this argument and make a modest suggestion: that the evidence from current physics is inconclusive.     

Does the Higgs Mechanism Exist?

This paper explores the argument structure of the concept of spontaneous symmetry breaking in the electroweak gauge theory of the Standard Model: the so‐called Higgs mechanism. As commonly understood, the Higgs argument is designed to introduce the masses of the gauge bosons by a spontaneous breaking of the gauge symmetry of an additional field, the Higgs field. The technical derivation of the Higgs mechanism, however, consists in a mere reshuffling of degrees of freedom by transforming the Higgs Lagrangian in a gauge‐invariant manner. This already raises serious doubts about the adequacy of the entire manoeuvre. It will be shown that no straightforward ontic interpretation of the Higgs mechanism is tenable, since gauge transformations possess no real instantiations. In addition, the explanatory value of the Higgs argument will be critically examined.     

Children's judgments in theory choice tasks: scientific rationality in childhood.

The current research examined whether children could use certain metaconceptual criteria such as the range of explanation, non-ad hocness of explanation, empirical consistency, and logical consistency to choose between competing accounts of physical phenomena. The tasks were constructed so that the conceptual content of the explanations to be evaluated was either consistent, inconsistent, or neutral with regard to children's prior knowledge. It was found that even 7-year-olds could use metaconceptual criteria such as the range, empirical consistency, and logical consistency of theories when the theories did not violate their beliefs. However only older children (11-year-olds) showed a systematic preference for non-ad hoc theories over ad hoc ones. The findings are consistent with recent work in the philosophy of science showing that, in evaluating theoretical alternatives, scientists are influenced by their prior beliefs about the domain being considered. This research demonstrates that even young children share some of the cognitive underpinnings of scientific rationality that scientists do.     

Creativity and modelling the measurement process of the Higgs self-coupling at the LHC and HL-LHC

This paper provides an account of the nature of creativity in high-energy physics experiments through an integrated historical and philosophical study of the current and planned attempts to measure the self-coupling of the Higgs boson by two experimental collaborations (ATLAS and CMS) at the Large Hadron Collider (LHC) and the planned High Luminosity Large Hadron Collider (HL-LHC). A notion of creativity is first identified broadly as an increase in the epistemic value of a measurement outcome from an unexpected transformation, and narrowly as a condition for knowledge of the measurement of the self-coupling of the Higgs. Drawing upon Tal’s model-based epistemology of measurement (2012) this paper shows how without change to ‘readings’ (or ‘instrument indicators’) a transformation to the model of the measurement process can increase the epistemic value of the measurement outcome. Such transformations are attributed to the creativity of the experimental collaboration. Creativity, in this context, is both a product, a creative and improved model, and the distributed collaborative process of transformation to the model of the measurement process. For the case of the planned measurements at the HL-LHC, where models of the measurement process perform the epistemic function of prediction, creativity is included in the models of the measurement process, both as projected quantified creativity and as an assumed property of the future collaborations.

     

Possible influence of electrostatics in molecular bonding at supported metal nanoparticles

A mechanism is proposed for interaction between gas molecules and supported metal nanoparticles. Hot electrons that are formed via electron–hole pair excitations caused by exothermic reactions on the particles, enter into the insulating support, thereby leaving a positive charge that is distributed over the volume of the nanoparticle. The lifetime of the charge depends on the size of the metal particle and on the electronic and dielectric properties of the support, and may be too short for equilibrium to be established between the particle and its surroundings on the time scale of the chemical reaction. The electrostatic potential of the particle depends on its size, and therefore the position of the d-density of states of the particle, and thus the interaction with adsorbed molecules may be tuned by changing particle size. Thus, catalytic activity and selectivity may be affected for chemical reactions.     

Autonomy, Liberalism, and Anti-Perfectionism

John Christman has recently objected to substantive conceptions of autonomy on the grounds that they introduce unwanted perfectionism into political thinking. I defend substantive conceptions of autonomy against Christman’s critique on two fronts. First, I defend substantive conceptions of autonomy against the charge that their utilisation in political theory would result in the inappropriate exclusion from democratic respect of individuals in oppressive relations. Second, I defend substantive conceptions of autonomy from the charge that they fail the ‘endorsement constraint’, i.e. that incorporating a substantive conception of autonomy into the concept of the person at the heart of a political theory would be alienating for citizens.

Annihilating the Nothing: Hegel and Nishitani on The Self-Overcoming of Nihilism

In Nishitani’s The Self-Overcoming of Nihilism, Nishitani explores, among other related topics, the history of the problem of Nihilism in the West. Conspicuously absent from Nishitani’s historical analysis is the thought of Friedrich Heinrich Jacobi, who famously raised the charge of Nihilism against Fichte’s philosophy in 1799. As is evident from a variety of Hegel’s texts, Hegel explicitly responds to Jacobi’s charge against Speculative Idealism and designs his philosophy in part as a response to Jacobi’s charge of Nihilism. On the one hand, Nishitani fails to appreciate Hegel’s philosophy as a response to the problem of Nihilism because he has an incomplete possession of the history of the problem. On the other hand, Nishitani’s critique of Hegel begs the question. Nishitani’s dogmatic rejection of Hegel appears to be grounded in his methodological approach to the philosophy of history, which assumes the falsehood of Hegel’s account. Jacobi’s charge against Speculative Idealism consists in the Idealist’s failure to account for the very existence of the world. On his view, philosophy is Nihilism because the world disappears completely from philosophical speculation. Hegel attempts to overcome this charge of Nihilism by re-thinking the structure and content of reason.     

Pragmatic Unification, Observation and Realism in Astroparticle Physics

Astroparticle physics is a recent sub-discipline of physics that emerged from early cosmic ray studies, astrophysics, and particle physics. Its theoretical foundations range from quantum field theory to general relativity, but the underlying “standard models” of cosmology and particle physics are far from being unified. The paper explores the pragmatic strategies employed in astroparticle physics in order to unify a disunified research field, the concept of observation involved in these strategies, and their relations to scientific realism.     

MAN OF SCIENCE,MAN OF FAITH: PIERRE DUHEM'S “PHYSIQUE DE CROYANT”

The essay “Physique de croyant” is an important statement of Pierre Duhem's position on the relation between his science and his religion. Duhem trod a difficult path, some might say an impossible one, in Republican France because he was both a physicist and a devout Catholic. In this essay, using “Physique de croyant” as a touchstone, I explore the way in which he tried to reconcile his conflicting allegiances. There are several strands in Duhem's strategy that need to be teased out. First, Duhem sought to defend his science against the charge that it was materialist and atheist. He did this with his claim, usually called the autonomy thesis, that physics and metaphysics are fundamentally different enterprises—that physics, properly conducted, has no metaphysical implications and requires no metaphysical support. This did not deny metaphysics its rightful territory. Second, Duhem used his segregationist position to defend the Roman Catholic Church against the assaults of the positivist scientism then in favor with the Republicans. Third, he also sought to protect his science against fellow Catholics who wanted to use it for polemical purposes. I develop and evaluate these lines of defense.     

Space,time and memory: tales from a long road

Points, lines and surfaces are the basic elements of Euclidean geometry. In this paper, accompanying a keynote at ICSC 2018, we will explore how, in physics, cognition and our lived experience, it is often better to think in terms of interconnected threads than an evolving state of the world now. In physics ‘now’ is an illusion, merely a convenient construction, each particle and person is more like an independent strand in space–time, and similarly, in our minds, strands of memories from different roles and contexts flow almost independently. Paths create lines on the map and may be inscribed as signs in the landscape, but our journeys along paths create temporal threads that interweave as we meet along the way. This paper draws on my research over many years on time and user interaction and also my personal experiences during a thousand-mile walk around the periphery of Wales in 2013.     

Ad Hominem Fallacies, Bias, and Testimony

An ad hominem fallacy is committed when an individual employs an irrelevant personal attack against an opponent instead of addressing that opponent’s argument. Many discussions of such fallacies discuss judgments of relevance about such personal attacks, and consider how we might distinguish those that are relevant from those that are not. This paper will argue that the literature on bias and testimony can helpfully contribute to that analysis. This will highlight ways in which biases, particularly unconscious biases, can make ad hominem fallacies seem effective, even when the irrelevance is recognized.     

Aristotle’s Notion of ‘Place’ in the Context of Present-day Physics

The article deals with Aristotle’s conception of ‘place’, which is of cruсial importance for his theory of motion. It is shown that in the physics of Aristotle there is no concept of spасe; instead, there is the notion of ‘place’ of a body (topos). Aristotle considered ‘place’ as the first boundary of a body embracing (containing) the body in question. The author shows the incommensurability between the spatial ideas of the Stagirite and the similar ideas of Newtonian physics. The article states that in order to give an adequate reconstruction of Aristotle’s concept of ‘place’ we need to take into account two different levels of consideration: local and global. Places locally separable (from bodies) cannot be separated on the global level. In Newtonian physics, bodies are separable from places on both levels. The nature of parallelism of ideas between Aristotle’s conception of ‘place’ and the notions of space in present-day physics is analysed.     

Fans and Identity

ABSTRACT

This paper develops an understanding of the nature of sport fans that helps rebut the charge of nihilism leveled against identity anti-essentialism as represented in the work of Butler, Appiah, and Rorty. Through focusing on what Russell calls the ‘arbitrary’ yet committed nature of being a fan of sport (i.e. a fan’s fandom has a causal explanation not a reasoned justification but nonetheless deep meaning for the fan), I argue that we can see the anti-essentialist accounts of gender, race, and selfhood offered by Butler, Appiah, and Rorty respectively as claiming that this arbitrary, but at the same time meaningful, nature is consistent across all identities. Passionate commitment in the face of often self-consciously recognized arbitrary fandom exemplifies identity anti-essentialism, and it is in terms of it that the charge of nihilism against identity anti-essentialism (i.e. identity anti-essentialism makes identity insubstantial and politically ineffective) leveled by those such as Nussbaum, Habermas, and Rawls, is undercut. With that case made, I conclude on a political note. I observe that the rise and role of identity in contemporary politics, especially nativist, nationalist, and populist politics, can be both explained (at least in part) as well as defended against by seeing the growing acceptance among elites of identity anti-essentialism and its fan-like quality. Galvanizing many on the ‘right’ to fight elites by fighting against the identity anti-essentialism binding them together, it is by ‘doubling down’ on identity anti-essentialism and its embrace of the fan-like play of identity that hope lies in fighting against nativism, nationalism, and populism.     

Liberal Naturalism: The Curious Case of Hegel

Abstract

My aim in this paper is to defend the claim that the absolute idealism of Hegel is a liberal naturalist position against Sebastian Gardner’s claim that it is not genuinely naturalistic, and also to defend the position of ‘liberal naturalism’ from Ram Neta’s charge that there is no logical space for it to occupy. By ‘liberal naturalism’, I mean a doctrine which is a non-reductive form of philosophical naturalism. Like Fred Beiser, I take the thesis of liberal naturalism to find support in the idealism of Hegel. I begin by first explaining what philosophical naturalism amounts to. I then move on to show, using Finn Spicer’s and Alison Stone’s understandings of philosophical naturalism, how there is a stronger form of philosophical naturalism but also how there is a weaker form as well. Having established the distinction between stronger and weaker variants of philosophical naturalism, I discuss Sebastian Gardner’s recent objections to treating absolute idealism as a genuinely naturalist position. I argue that Gardner is incorrect to claim that absolute idealism is not a genuinely naturalist position on both historical and interpretive grounds, where to do so I bring in features of Hegel’s idealism to show that Hegel was committed to liberal naturalism. In the next section of the paper, I address Ram Neta’s charge that there is no logical space for liberal naturalism. To counter this claim, I offer an Hegelian diagnosis of Neta’s charge and argue that Neta’s concern about the possibility of liberal naturalism is illegitimately motivated.     

Sexism and the Effectiveness of Femvertising in China: A Corporate Social Responsibility Perspective

The present study draws on theories and prior research on corporate social responsibility (CSR) and gender attitudes (i.e., sexism) to understand young Chinese peoples’ responses toward women-empowering advertising (i.e., femvertising). We conducted two experiments in which male and female Chinese college students (232 in Study 1 and 231 in Study 2) were exposed to either women-empowering or control advertisements (traditional ad in Study 1 and gender-irrelevant ad in Study 2) and reported their attitudes about the ads as well as their purchase intentions toward the advertised products (shampoo and smartphone, respectively). In line with our predictions, both experiments showed that messaging about women’s empowerment in advertising can induce perceptions of CSR, thereby increasing favorable responses such as enhanced positive ad attitudes and increased purchase intentions toward the advertised products. Moreover, hostile sexism was negatively associated with consumer responses toward femvertising such that the lower participants’ hostile sexism, the more positive ad attitudes and stronger purchase intent participants they reported. However, benevolent sexism was not predictive of consumer responses toward femvertising. These results offer insights into people’s responses toward women-empowering advertisements and also have practical implications for advertisers and marketers who are interested in using such an advertising tactic to promote products and services.

     

Marx and Cohen on Exploitation and the labor theory of value

Gerald A. Cohen, in ‘The Labor Theory of Value and the Concept of Exploitation’, argues that, contrary to the traditional assumption, Marx's charge of exploitation against capitalism does not require the labor theory of value. However, there is a related but simpler basis for the charge. Hence Marx's criticism can stand even if the labor theory of value falls. Furthermore, he argues that the labor theory of value is false. It is argued here that Cohen is mistaken; the charge Marx makes against capitalism does require the labor theory of value. Cohen's conception of exploitation is weaker than Marx's both theoretically and morally. It is also argued that Cohen's criticisms of the labor theory of value rest on misunderstandings of the theory and Marx's methodology.     

Bloch's Paradox and the Nonlocality of Chance

I show how an almost exclusive focus on the simplest case—the case of a single particle—along with the commonplace conception of the single‐particle wave function as a scalar field on spacetime contributed to the perception, first brought to light by I. Bloch, that there existed a contradiction between quantum theory with instantaneous state collapses and special relativity. The incompatibility is merely apparent since treating wave‐function values as hypersurface dependent avoids the contradiction. After clarifying confusions which fueled the perception of a paradox, I elaborate on an analysis of the wave function due to Wayne Myrvold to show that nothing special, or ad hoc, is required in treating wave‐function values, even in the single‐particle case, as hypersurface–dependent; rather, the hypersurface dependence of these values is the natural development of nonlocal entanglement in the context of the relativity of simultaneity. Properly understood, what Bloch’s paradox reveals is that the combination of nonlocal entanglement together with a hypersurface‐dependent process of state collapse conflicts with the thesis of spatiotemporal separability and, in particular, with the idea that chances are local matters of fact.     

Non-Inferential Aspects of Ad Hominem and Ad Baculum

The aim of the paper is to explore the interrelation between persuasion tactics and properties of speech acts. We investigate two types of arguments ad: ad hominem and ad baculum. We show that with both of these tactics, the structures that play a key role are not inferential, but rather ethotic, i.e., related to the speaker’s character and trust. We use the concepts of illocutionary force and constitutive conditions related to the character or status of the speaker in order to explain the dynamics of these two techniques. In keeping with the research focus of the Polish School of Argumentation, we examine how the pragmatic and rhetorical aspects of the force of ad hominem and ad baculum arguments exploit trust in the speaker’s status to influence the audience’s cognition.
