Earth-shaping catastrophic events have long focused the attention of the geographical and geological sciences, and captured the public imagination. During the past 40 years, neocatastrophism has emerged as a key paradigm that reflects widespread changes involving cultural, scientific, political and technological spheres. Nonetheless, the extent, chronology and origin of this trend are equivocal. Here, we use Google Ngram to quantitatively explore the recent development of catastrophism. We elucidate a discernable rise in neocatastrophic thinking during the last quarter of the twenty-first (...) century that can be linked to the environmental awakening of the 1960s. It is suggested that these discourses of ‘shock’ and ‘fear’ partly correspond to a media-driven dramatization of natural hazards, exploited by scientists and journalists to attract wider readership.

This paper details the ways that gender structures our senses of agency on an enactive framework. While it is common to discuss how gender influences higher, narrative levels of cognition, as with the formulation of goals and in considerations about our identities, it is less clear how gender structures our more immediate, embodied processes, such as the minimal sense of agency. While enactivists often acknowledge that gender and other aspects of our socio-cultural situatedness shape our cognitive processes, there is little (...) work on how this shaping takes place. In order to provide such an account, I will first look at the minimal and narrative senses of agency (Gallagher 2012), a distinction that draws from work on minimal and narrative selves (Zahavi 2010). Next I will explain the influence of the narrative sense of agency on the minimal sense of agency through work on intention-formation (Pacherie 2007). After a discussion of the role of gender in the narrative sense of agency, I’ll expand on work by Haslanger (2012) and Young (1980) to offer three ways in which gender influences the minimal sense of agency, showing the effect that gender has on how we perceive our possibilities for interaction in a phenomenologically immediate, pre-reflective manner.

Scientific and technological progress might change people’s capabilities or incentives in ways that would destabilize civilization. For example, advances in DIY biohacking tools might make it easy for anybody with basic training in biology to kill millions; novel military technologies could trigger arms races in which whoever strikes first has a decisive advantage; or some economically advantageous process may be invented that produces disastrous negative global externalities that are hard to regulate. This paper introduces the concept of a vulnerable world: (...) roughly, one in which there is some level of technological development at which civilization almost certainly gets devastated by default, i.e. unless it has exited the “semi-anarchic default condition”. Several counterfactual historical and speculative future vulnerabilities are analyzed and arranged into a typology. A general ability to stabilize a vulnerable world would require greatly amplified capacities for preventive policing and global governance. The vulnerable world hypothesis thus offers a new perspective from which to evaluate the risk-benefit balance of developments towards ubiquitous surveillance or a unipolar world order. (shrink)

This paper investigates the significance of T-duality in string theory: the indistinguisha- bility with respect to all observables, of models attributing radically different radii to space – larger than the observable universe, or far smaller than the Planck length, say. Two interpretational branch points are identified and discussed. First, whether duals are physically equivalent or not: by considering a duality of the familiar simple harmonic oscillator, I argue that they are. Unlike the oscillator, there are no measurements ‘outside’ string theory (...) that could distinguish the duals. Second, whether duals agree or disagree on the radius of ‘target space’, the space in which strings evolve according to string theory. I argue for the latter position, because the alternative leaves it unknown what the radius is. Since duals are physically equivalent yet disagree on the radius of target space, it follows that the radius is indeterminate between them. Using an analysis of Brandenberger and Vafa (1989), I explain why – even so – space is observed to have a determinate, large radius. The conclusion is that observed, ‘phenomenal’ space is not target space, since a space cannot have both a determinate and indeterminate radius: instead phenomenal space must be a higher-level phenomenon, not fundamental.

The notion of more truth, or of more truth and less falsehood, is central to epistemology. Yet, I argue, we have no idea what this consists in, as the most natural or obvious thing to say—that more truth is a matter of a greater number of truths, and less falsehood is a matter of a lesser number of falsehoods—is ultimately implausible. The issue is important not merely because the notion of more truth and less falsehood is central to epistemology, but (...) because an implicit, false picture of what this consists in underpins and gives shape to much contemporary epistemology.

"Ethical thought has no chance of being everything it seems." Bernard Williams offered this cryptic remark in Ethics and the Limits of Philosophy, and in this chapter I argue that understanding it is the key to understanding Williams' skepticism about moral theory and about systematization in ethics. The difficulty for moral philosophy, Williams believed, is that ethics looks one way to embodied, active agents, but looks entirely different when considered from the standpoint of theory. This, in turn, means that following (...) a moral theory is a sure route to practical alienation. I argue that once we see it for what it is, we can see that Williams own skepticism undermines his later attempts to vindicate Truthfulness. Moreover, given the pervasiveness of reflective practical alienation in ordinary life, it leaves us with a difficult question: what would a non-alienated ethical existence even look like for us?

ABSTRACTPolitical rule depends upon public discourse as it requires negotiation and compromise of conflicting interests. Public discourse includes activities that can be described as cause lawyering, lobbying, and rule entrepreneurship. The rule of law supports public discourse through, inter alia, the right to petition. The right to petition requires identification of those engaged in public discourse through petition. This requirement reflects a principle of general application. Solicitors owe an ethical duty to support the rule of law, including the right to (...) petition. Lawyers without a specific duty to uphold the rule of law have ethical duties to maintain the reputation of the legal system and their legal profession. Lawyers, including solicitors, are frequent contributors to public discourse. Lawyers sometimes resist identifying the clients or client groups they represent in public discourse on the ground of the need to protect client confidentiality. This resistance is not ethically well reasoned, a... (shrink)

Weyl symmetry of the classical bosonic string Lagrangian is broken by quantization, with profound consequences described here. Reimposing symmetry requires that the background space-time satisfy the equations of general relativity: general relativity, hence classical space-time as we know it, arises from string theory. We investigate the logical role of Weyl symmetry in this explanation of general relativity: it is not an independent physical postulate but required in quantum string theory, so from a certain point of view it plays only a (...) formal role in the explanation.

A version of relationism that takes spatiotemporal structures—spatial geometry and a standard of inertia—to supervene on the history of relations between bodies is described and defended. The account is used to explain how the relationist should construe models of Newtonian mechanics in which absolute acceleration manifestly does not supervene on the relations; Ptolemaic and Copernican models for example. The account introduces a new way in which a Lewis-style ‘best system’ might capture regularities in a broadly Humean world; a defence is (...) given against a charge of indeterminism that applies to any such approach to laws.

We review the various factors that limit adaptation by natural selection. Recent discussion of constraints on selection and, conversely, of the factors that enhance “evolvability”, have concentrated on the kinds of variation that can be produced. Here, we emphasise that adaptation depends on how the various evolutionary processes shape variation in populations. We survey the limits that population genetics places on adaptive evolution, and discuss the relationship between disparate literatures. BioEssays 22:1075–1084, 2000. © 2000 John Wiley & Sons, Inc.

I want to review some ways in which Quantum Mechanics seems to affront our “common-sense” notions of identity. Let’s start with a list.

Hyman (1999, 2006) argues that knowledge is best conceived as a kind of ability: S knows that p iff S can φ for the reason that p. Hyman motivates this thesis by appealing to Gettier cases. I argue that it is counterexampled by a certain kind of Gettier case where the fact that p is a cause of the subject’s belief that p. One can φ for the reason that p even if one does not know that p. So knowledge (...) is not best conceived as an ability of this kind. (shrink)

Much apprehension has been expressed by philosophers about the method of renormalisation in quantum field theory, as it apparently requires illegitimate procedure of infinite cancellation. This has lead to various speculations, in particular in Teller (1989). We examine Teller's discussion of perturbative renormalisation of quantum fields, and show why it is inadequate. To really approach the matter one needs to understand the ideas and results of the renormalisation group, so we give a simple but comprehensive account of this topic. With (...) this in hand, we explain how renormalisation can and should be understood. One thing that is revealed is that apparently very successful theories such as quantum electro-dynamics cannot be universally true; resolving the tension between success and falsity leads to a picture in which any theory may be viewed as irreducibly phenomenological. We explain how, and argue that the support for this view is tenuous at best. (shrink)

There is a familiar teleological picture of epistemic normativity on which it is grounded in the goal or good of belief, which is taken in turn to be the acquisition of truth and the avoidance of error. This traditional picture has faced numerous challenges, but one of the most interesting of these is an argument that rests on the nearly universally accepted view that this truth goal, as it is known, is at heart two distinct goals that are in tension (...) with one another. This paper will look more closely at the standard way of understanding the truth goal, drawing out both its explicit and implicit features. My aim will be to show that this conception of the truth goal is deeply mistaken, to propose and defend an alternative model, and to show how this alternative model restores the unity of the goal and its potential to ground and explain the normative dimensions of belief.

I develop a broadly reliabilist theory of non-ideal epistemic rationality and argue that if it is correct we should reject the recently popular idea that the standards of non-ideal epistemic rationality are mere social conventions.

Heikki Patomäki claims, in ‘After Critical Realism?’, that Roy Bhaskar's early critical realism is inadequate to the contemporary natural and social sciences. He claims that Bhaskar defends anthropomorphic conceptions of causality; fails to recognise real change; and fails to underlabour for futures studies. These claims are based on a series of misunderstandings, notably about the nature and implications of underlabouring. Underlabouring is discussed in terms of the disclosure and transformation of the deep categorial structures of science and theory.

This paper considers the implications for the relational-substantival debate of observations of parity nonconservation in weak interactions, a much neglected topic. It is argued that 'geometric proofs' of absolute space, first proposed by Kant (1768), fail, but that parity violating laws allow 'mechanical proofs', like Newton's laws. Parity violating laws are explained and arguments analogous to those of Newton's Scholium are constructed to show that they require absolute spacetime structure--namely, an orientation--as Newtonian mechanics requires affine structure. Finally, it is considered (...) how standard relationist responses to Newton's argument might respond to the new challenge of parity nonconservation. (shrink)

It is widely thought that moral obligations are necessarily guidance giving. This supposed fact has been put to service in defence of the ‘ought-implies-can’ principle according to which one cannot be morally obligated to do the impossible, since impossible-to-satisfy obligations would not give guidance. It is argued here that the supposed fact is no such thing; moral obligations are not necessarily guiding giving, and so the ‘guidance argument’ for ought-implies-can fails. This is the result of no non-trivial condition being ‘luminous’.

ABSTRACTIn ‘The Principles of Art’, R. G. Collingwood argues that art is the imaginative expression of emotion. So much the worse, then, for Collingwood. The theory seems hopelessly inadequate to the task of capturing art’s extension: of encompassing all the works we generally suppose should be rounded up under the concept. A great number of artworks, and several art forms, have nothing to do with emotion. But it would be surprising were Collingwood philistine enough to think that art is only (...) ever concerned with communicating quotidian affective states, like anger, fear or love. Surely he has some more sophisticated notion of emotion in mind, and quite probably of expression too. And it turns out that those sophisticated notions can be pushed towards a version of the expression theory that meets the extensional challenge. If we interpret Collingwood as saying that expression is a particular application of imagination, and that imagination is the faculty that refines ideas of emotions, and that ‘emotions’... (shrink)

I defend extreme formalism about the aesthetics of inorganic nature. I outline the general issue over aesthetic formalism as it manifests itself in the visual arts. The main issue is over whether we need to know about the history of artworks in order to appreciate them aesthetically. I then turn to nature and concede that with organic nature we need to know a thing's biological kinds if we are fully to appreciate it. However, with in organic nature I deny that (...) we need to know the deeper nature of the things we experience. What is important, I argue, are the appearances of those things not their real natures. I consider the beauty of clouds, which depends on an illusion of solidity, and I argue that scientific knowledge does not reveal beauty that is not available to the ignoramous. There is only the beauty of appearances, and it does not matter whether those appearances are accurate or illusory. (shrink)

This is the introduction to the special issue of Studies in the History and Philosophy of Modern Physics on the emergence of spacetime in quantum theories of spacetime.

In this paper we critically review the various attempts that have been made to understand quantum field theory. We focus on Teller's (1990) harmonic oscillator interpretation, and Bohm et al.'s (1987) causal interpretation. The former unabashedly aims to be a purely heuristic account, but we show that it is only interestingly applicable to the free bosonic field. Along the way we suggest alternative models. Bohm's interpretation provides an ontology for the theory--a classical field, with a quantum equation of motion. This (...) too has problems; it is not Lorentz invariant. (shrink)

There has been considerable recent philosophical debate over the implications of many particle quantum mechanics for the metaphysics of individuality (cf. Huggett [1997]). In this paper I look at things from a rather different perspective: by investigating the significance of permutation symmetry. I consider how various philosophical positions link up to the physical postulate of the indistinguishability of permuted states-permutation invariance-and how this postulate is used to explain quantum statistics. I offer an explanation of the statistics that relies on the (...) neglected parallel between permutations and covariant spatial transformation. And I explore the parallel, showing that a further kind of symmetry explains why permutations are invariant when spatial symmetries are not. (shrink)

The modeling of black holes is an important desideratum for any quantum theory of gravity. Not only is a classical black hole metric sought, but also agreement with the laws of black hole thermodynamics. In this paper, we describe how these goals are achieved in string theory. We review black hole thermodynamics, and then explicate the general stringy derivation of classical spacetimes, the construction of a simple black hole solution, and the derivation of its entropy. With that in hand, we (...) address some important philosophical and conceptual questions: the confirmatory value of the derivation, the bearing of the model on recent discussions of the so-called ‘information paradox’, and the implications of the model for the nature of space.

It is often argued that the requirement that moral obligations be ‘action guiding’ motivates the claim that one can be obligated to ϕ only if one can ϕ. I argue that even on its most plausible interpretation, this argument fails, since the reasoning behind it leads to the absurd conclusion that one is permitted to ϕ if one cannot ϕ.

Philosophy for Children (P4C) is an approach to learning and teaching that aims to develop reasoning and judgement. Students learn to listen to and respect their peers' opinions, think creatively and work together to develop a deeper understanding of concepts central to their own lives and the subjects they are studying. With the teacher adopting the role of facilitator, a true community develops in which rich and meaningful dialogue results in enquiry of the highest order. Each chapter is written by (...) a leading P4C expert and provides an introduction to the relationship between P4C and the subject area, lesson stimuli and activities for extending and deepening students' thinking. The book includes: • guidance on how to embed P4C in curriculum subjects in a crowded and demanding secondary curriculum timetable • troubleshooting advice for the teacher-turned-facilitator • a companion website containing useful links, downloadable resources and material to display on your interactive whiteboard. Edited and collated by the UK's leading P4C organisation, this book introduces a rationale for using and adapting P4C in the secondary curriculum. (shrink)

Public acceptance is often seen as a key reason why water-recycling technology is rejected. A common assumption is that projects fail because the general public is unable to comprehend specialist information about risk and the belief that if the public were better informed, they would accept change more readily. This article suggests that rhetoric about acceptance is counterproductive in progressing sustainability as it does not address issues relating to institutional arrangements and reinforces a dichotomy between expert and lay groups. Instead, (...) it is argued that institutional change is needed to build opportunities for constructive public engagement. The failure to implement sustainable water use through recycling can be understood as the result of several factors including present cost structures for water, institutional conservatism, administrative fragmentation, and inadequate involvement of communities in planning. Achieving sustainable water use through recycling may require better coordination between agencies and integrated government policies. (shrink)

Several authors have made the argument that because blind evolutionary processes produced human intelligence on Earth, it should be feasible for clever human engineers to create human-level artificial intelligence in the not-too-distant future. This evolutionary argument, however, has ignored the observation selection effect that guarantees that observers will see intelligent life having arisen on their planet no matter how hard it is for intelligent life to evolve on any given Earth-like planet. We explore how the evolutionary argument might be salvaged (...) from this objection, using a variety of considerations from observation selection theory and analysis of specific timing features and instances of convergent evolution in the terrestrial evolutionary record. We find that, depending on the resolution of disputed questions in observation selection theory, the objection can either be wholly or moderately defused, although other challenges for the evolutionary argument remain.

This article proposes that a general theory of assessment of historical testimony should do justice to the long tradition of adjudication in accordance with maxims of reliability and competence. I argue that an explanatory genealogical theory (along lines first adumbrated by Charles Seignobos) satisfies this condition, and that it has further notable virtues: respect for the strengths of rival theories, regard for the links between adjudication of testimony and other basic procedures of historical inquiry, and the promise of profitable lines (...) of investigation.

In recent years, the responsibility of corporations has been widely discussed. However, there is no general agreement as regards what CSR is exactly. Due to the indefinite nature of CSR, the term actually embraces several ideas and different contents. A very widespread understanding of CSR defines the subject as (strategic) corporate philanthropy, including operations such as corporate giving, corporate volunteering, corporate foundations, etc. The philanthropic approach to CSR implies that corporations must take responsibility beyond their core business activities. This article (...) argues that a philanthropic approach to CSR is problematic. Moreover, such a conceptualisation strengthens the perception that making Profits is immoral; therefore, it endangers the basis of corporations' license-to-operate in the long run. (shrink)

Escalation of commitment causes people to continue a failing course of action. We study the role of construal level in such escalation of commitment. Consistent with the widely held view of construal level as a primed effect, we employed a commonly used prime for manipulating this construct in a laboratory experiment. Our findings revealed that the prime failed to produce statistically significant differences in construal level, which was measured using the Behavior Identification Form. Furthermore, there was no effect of the (...) prime on escalation of commitment, or on constructs that have previously been linked to construal level such as the perceived importance of feasibility considerations relative to desirability considerations, and the number of pros and cons that subjects can think of.Interestingly, however, subjects’ actual construal level scores on the BIF were found to significantly affect escalation. Specifically, our findings show that people with a low construal level are less willing to continue a failing project. This relation is mediated by the perceived importance of the feasibility of the project relative to its desirability. For people with a low construal level, the perceived importance of feasibility relative to desirability is higher, which in turn makes escalation of commitment less likely.Our findings are consistent with prior research suggesting that priming construal level may not always be effective. Thus, while construal level has typically been regarded as a state-like variable that can be primed, in this study, we show that construal level may also be considered as a trait. (shrink)

Mark Pennington’s Robust Political Economy is a systematic exposition of a framework for analyzing institutional performance. The Robust Political Economy framework evaluates institutions according to their ability to solve knowledge and incentive problems. On grounds of robustness, Pennington combines insights from Austrian market-process theory and public-choice theory to defend classical liberalism from several compelling critiques. These include theories of market failure in economics; communitarian, deliberative-democratic, and liberal-egalitarian theories of justice; and concerns with social capital, domestic and international poverty, and ecology.

Consider a toothache, or a feeling of intense pleasure, or the sensation you would have if you looked impassively at an expanse of colour. In each case, the experience can easily be thought to fill time by being present throughout a period. This way of thinking of conscious experience is natural enough, but it is in deep conflict with the view that physical processes are ultimately responsible for experience. The problem is that physical processes are related to durations in a (...) very different way—not by being wholly present at each instant or sub-period, but by having temporal parts that are. There is a choice to be made, therefore, between preserving this common way of thinking of experience and preserving the fundamentality of processes. The first option holds fixed the view of experiences as occurring throughout time and takes this to constrain the category of entity to which they are identical, or upon which they supervene. The second option abandons this common view of experience by taking up a perspective on which we experience things in the world and their properties as existing or occurring a certain way, and mistakenly ascribe this ontological character to our experience as well. The second option is ultimately the better option, however, since only it can make sense of the facts of our experience. (shrink)

Paul Teller's new book, “An Interpretive Introduction to Quantum Field Theory”, is a pioneering work. To the best of our knowledge it is the first book by a philosopher devoted not only to explaining what quantum field theory is, but to clarifying the conceptual issues and puzzles to which the theory gives rise. As such it is an important book, which we hope will greatly stimulate work in the area as other philosophers and physicists react to it.

I discuss a model inspired from the string/brane framework, in which our Universe is represented (after perhaps appropriate compactification) as a three brane, propagating in a bulk space time punctured by D0-brane (D-particle) defects. As the D3-brane world moves in the bulk, the D-particles cross it, and from an effective observer on D3 the situation looks like a “space-time foam” with the defects “flashing” on and off (“D-particle foam”). The open strings, with their ends attached on the brane, which represent (...) matter in this scenario, can interact with the D-particles on the D3-brane universe in a topologically non-trivial manner, involving splitting and capture of the strings by the D0-brane defects. Such processes are consistently described by logarithmic conformal field theories on the world-sheet of the strings. Physically, they result in effective decoherence of the string matter on the D3 brane, and as a result, of CPT Violation, but of a type that implies an ill-defined nature of the effective CPT operator. Due to electric charge conservation, only electrically neutral (string) matter can exhibit such interactions with the D-particle foam. This may have unique, experimentally detectable (in principle), consequences for electrically-neutral entangled quantum matter states on the brane world, in particular the modification of the pertinent Einstein-Podolsky-Rosen (EPR) Correlation in neutral mesons in an appropriate meson factory. For the simplest scenarios, the order of magnitude of such effects might lie within the sensitivity of upgraded φ-meson factories. (shrink)
