A subtheory of the theory of self-referential truth known as FS is shown to be weak as a theory of truth but equivalent to full FS in its proof-theoretic strength.

We define a class of functions, the descent recursive functions, relative to an arbitrary elementary recursive system of ordinal notations. By means of these functions, we provide a general technique for measuring the proof-theoretic strength of a variety of systems of first-order arithmetic. We characterize the provable well-orderings and provably recursive functions of these systems, and derive various conservation and equiconsistency results.

Probably the two most famous examples of elementary embeddings between inner models of set theory are the embeddings of the universe into an inner model given by a measurable cardinal and the embeddings of the constructible universeLinto itself given by 0#. In both of these examples, the “target model” is a subclass of the “ground model”. It is not hard to find examples of embeddings in which the target model is not a subclass of the ground model: ifis a generic (...) ultrafilter arising from forcing with a precipitous ideal on a successor cardinalκ, then the ultraproduct of the ground model viacollapsesκ. Such considerations suggest a classification of how close the target model comes to “fitting inside” the ground model.Definition 1.1. LetMandNbe inner models of ZFC, and letj:M→Nbe an elementary embedding. Theco-critical pointofjis the least ordinalλ, if any exist, such that there isX⊆λ, X∈NbutX∉M.

In a modal system of arithmetic, a theory S has the modal disjunction property if whenever $S \vdash \square\varphi \vee \square\psi$ , either $S \vdash \square\varphi$ or $S \vdash \square\psi. S$ has the modal numerical existence property if whenever $S \vdash \exists x\square\varphi(x)$ , there is some natural number n such that $S \vdash \square\varphi(\mathbf{n})$ . Under certain broadly applicable assumptions, these two properties are equivalent.

This article examines the development of the concept of the value chain from the linear to the virtual conception of the chain, through the evolution of the literature from Michael Porter’s writings of the mid 1990s to the theorists of e-business and e-commerce in the later 1990s I argue that Porter’s account employs white metaphors and that writings on the virtual value chain both extend the white metaphors of Porter’s linear chain, and suggest a pronouncedly metaphysical system of thought (...) — one which has correlates in areas of thought, including Renaissance Neo-Platonism, cybernetics and the discourse of cyberspace. I suggest that this offers a model of the advance of metaphor — of its usure, as described by Derrida in his White Mythology — and that this model can be synthesised with the views of Ricoeur about the evolution of metaphor towards symbolism. When we apply these ideas of Derrida and Ricoeur to the development of the White Metaphor of the linear chain towards a progressive symbolism, we can see a correlation between the complex causality inferred as a feature of the virtual chain and the cosmological affinities of Renaissance notions of causation.

This paper compares the roles classical and intuitionistic logic play in restricting the free use of truth principles in arithmetic. We consider fifteen of the most commonly used axiomatic principles of truth and classify every subset of them as either consistent or inconsistent over a weak purely intuitionistic theory of truth.

The first attempt at a systematic approach to axiomatic theories of truth was undertaken by Friedman and Sheard (Ann Pure Appl Log 33:1–21, 1987). There twelve principles consisting of axioms, axiom schemata and rules of inference, each embodying a reasonable property of truth were isolated for study. Working with a base theory of truth conservative over PA, Friedman and Sheard raised the following questions. Which subsets of the Optional Axioms are consistent over the base theory? What are the (...) proof-theoretic strengths of the consistent theories? The first question was answered completely by Friedman and Sheard; all subsets of the Optional Axioms were classified as either consistent or inconsistent giving rise to nine maximal consistent theories of truth.They also determined the proof-theoretic strength of two subsets of the Optional Axioms. The aim of this paper is to continue the work begun by Friedman and Sheard. We will establish the proof-theoretic strength of all the remaining seven theories and relate their arithmetic part to well-known theories ranging from PA to the theory of ${\Sigma^1_1}$ dependent choice.

I develop an account of private property that preserves public participation and access. A focus on the initial state of common ownership, labour, and the proviso reveals that standard Lockean defences of property ignore important common interests. In consequence, property rights over environmentally significant goods must be less strong than full liberal rights, and I show how these will be designed.

Over recent years, considerable attention has been paid to the National Health Service research governance and ethics approvals process in the UK. New regulations mean that approval from the Medicines and Healthcare Products Regulatory Agency is now also needed for conducting all clinical trials. Practical experience of gaining MHRA and sponsorship approval has yet to be described and critically explored in the literature. Our experience, from start to finish, of applying for these four approvals for a multicentre randomised controlled trial (...) of two licensed drugs for opiate detoxification in the prison setting is described here. In addition, the implications of the approvals process for research projects, particularly clinical trials, in terms of time and funding, and also indirect implications for NHS patients are discussed. Inconsistencies are discussed and suggestions that could improve and streamline the overall process are made. The current approvals process could now be hindering non-commercial clinical trials, leading to a loss of important evidence-based medical information. (shrink)

In this paper I outline the PAIR account of joint attention as a perceptual-practical, affectively charged intentional relation. I argue that to explain joint attention we need to leave the received understanding of propositions and propositional attitudes and the picture of content connected to it behind and embrace the notions of subject mode and position mode content. I also explore the relation between joint attention and communication.

Morals from Motives develops a virtue ethics inspired more by Hume and Hutcheson's moral sentimentalism than by recently-influential Aristotelianism. It argues that a reconfigured and expanded "morality of caring" can offer a general account of right and wrong action as well as social justice. Expanding the frontiers of ethics, it goes on to show how a motive-based "pure" virtue theory can also help us to understand the nature of human well-being and practical reason.

COVID-19 is unique in that it is the first global pandemic occurring amidst a crowded information environment that has facilitated the proliferation of misinformation on social media. Dangerous misleading narratives have the potential to disrupt ‘official’ information sharing at major government announcements. Using an interrupted time-series design, we test the impact of the announcement of the first UK lockdown on short-term trends of misinformation on Twitter. We utilise a novel dataset of all COVID-19-related social media posts on Twitter from the (...) UK 48 hours before and 48 hours after the announcement. We find that while the number of tweets increased immediately post announcement, there was no evidence of an increase in misinformation-related tweets. We found an increase in COVID-19-related bot activity post-announcement. Topic modelling of misinformation tweets revealed four distinct clusters: ‘government and policy’, ‘symptoms’, ‘pushing back against misinformation’ and ‘cures and treatments’. (shrink)

Theories of discourse bring to realism new ideas about how knowledge develops and how representations of reality are influenced. We gain an understanding of the conceptual aspect of social life and the processes by which meaning is produced. This collection reflects the growing interest realist critics have shown towards forms of discourse theory and deconstruction. The diverse range of contributions address such issues as the work of Derrida and deconstruction, discourse theory, Eurocentrism and poststructuralism. What unites all of the contributions (...) is a sense that it is essential to provide a realist alternative to the hitherto dominance of social constructionism, hermeneutics and postmodernism, over many of the issues discussed. By developing a realist perspective the different authors attempt to embed discourse within the structured nature of the reality of the world. Realism can situate language, discourse and ideology within context specific, or 'causally efficacious' circumstances. Realism can help to uncover issues of power, representation, and subjectivity and how discursive and other social practices produce real effects. This can help us understand the manner in which social structures are reproduced through various forms of ideology and discourse. And by knowing this, we can start to address questions concerning human emancipation and how the world is to be transformed. (shrink)

In this article I look at CR (critical realism)1 as chiefly exhibited in the seminal theory of Ron Bhaskar – in particular, his early theory of transcendental realism. I examine its mechanisms of thought and pick out some difficulties with the theorisation relative to its deployment by OS theorists and relative to recent attempts to deploy CR as a theory which can bridge the fork in the constructivist and realist areas known as a form of ‘divide’ in the discipline (fault (...) line). I also try and attempt a more in-depth philosophical analysis of the ideas of CR to gain an insight into its nature and what it can offer both as an apodictic system of philosophical insights with aspects of a belief system – but also relative to its realist-related claims towards veridical knowledge of kinds. I make comparisons with other theorists and philosophers including Kant, Derrida, Hume and Aristotle. I close with insights into how a closer scrutiny of CR thought as it is entering OS is necessary to understand the evolving nature of the inter-relationship of ontology and the ontic, in relation to the fault line described.

Michael Quante focuses on what Hegel has to say about such central concepts as action, person and will, and then brings these views to bear on contemporary debates in analytic philosophy. This book enables professional analytic philosophers and their students to understand the significance of Hegel's philosophy to contemporary theory of action. As such, it will contribute to the ever-increasing erosion of the barrier between the continental and analytic approaches to philosophy.

The body of work pre s ented in this issue and the next (Volume 12, Issue 1) arose from a question both editors had separately harboured for some years, namely: what role can philosophy play in the practice and conceptualisation of management? Contemporary discourses within the academic discipline of management have tended to err on the side of science, either in the striving for replicative and iterative advancement in the proof-laden establishment of ‘facts’ or, what is worse perhaps, the iterative (...) and replicative containment of knowledge within languages or discourse that force the writer and the reader into narrow confines of thought â€" and thus narrow lanes by which to survey the field of enquiry. Indeed the extent of one’s vision itself becomes constrained such that only those fields readily open to view from the confines of the discourse’s perspective are ever regarded as legitimate; science has a remarkable degree of parochialism built into its very axiology. Unfortunately so too has logic, the ultimate science of philosophy. As the Cambridge mathematician and Harvard metaphysician A.N. Whitehead concluded, “the final outlook of Philosophic thought cannot be based upon the exact statements that form the basis of the special sciences. The exactness is a fake”. (1941: 700) Never has Whitehead’s assertion been more true and yet more disregarded. (shrink)

How do we weigh the claims of current and future people when current exercise of rights to property conflict with sustainability? Are property rights over theseresources more limited due to the claims of posterity? Lockean property rights allow no right to degrade resources when doing so threatens the basic needs offuture generations. A stewardship conception of property rights can be developed, providing a justification for sustainable management legislation even whensuch law conflicts with the rights an owner would have, were the (...) resource under more full-blown ownership. A protection indicator can be developed that is sensitive to a range of empirical factors such as scarcity, renewability, importance of the resource, and seriousness and reversibility of potential harm. The stewardship conception of rights over environmental resources can be applied in policy settings, for example, in decisions over emissions limits and land-use patterns. Such harnessing of Lockean intuitions to argue for environmental protection is in sharp contrast to Locke’s usual employment by those keen to show that such protection violates owners’ rights.

Divided into four parts, this treatise begins with well-known criticisms of nonreligious ethics and then develops an atheistic metaethics. In Part 2, Martin criticizes the Christian foundation of ethics, specifically the ’divine command theory’ and the idea of imitating the life of Jesus as the basis of Christian morality. Part 3 demonstrates that life can be meaningful in the absence of religious belief. Part 4 criticizes the theistic point of view in general terms as well as the specific Christian doctrines (...) of the atonement, salvation, and the resurrection. (publisher, edited). (shrink)

The guiding inspiration of this book is the attraction and distance that mark the relation between anthropology and philosophy. This theme is explored through encounters between individual anthropologists and particular regions of philosophy. Several of the most basic concepts of the discipline—including notions of ethics, politics, temporality, self and other, and the nature of human life—are products of a dialogue, both implicit and explicit, between anthropology and philosophy. These philosophical undercurrents in anthropology also speak to the question of what it (...) is to experience our being in a world marked by radical difference and otherness. In The Ground Between, twelve leading anthropologists offer intimate reflections on the influence of particular philosophers on their way of seeing the world, and on what ethnography has taught them about philosophy. Ethnographies of the mundane and the everyday raise fundamental issues that the contributors grapple with in both their lives and their thinking. With directness and honesty, they relate particular philosophers to matters such as how to respond to the suffering of the other, how concepts arise in the give and take of everyday life, and how to be attuned to the world through the senses. Their essays challenge the idea that philosophy is solely the province of professional philosophers, and suggest that certain modalities of being in the world might be construed as ways of doing philosophy.

This thought provoking book uncovers a crisis in the political imagination, a wide-spread failure to provide the passionate sense of community "in which our need for belonging can be met." Seeking the answers to fundamental questions, Michael Ignatieff writes vividly both about ideas and about the people who tried to live by them—from Augustine to Bosch, from Rosseau to Simone Weil. Incisive and moving, The Needs of Strangers returns philosophy to its proper place, as a guide to the art (...) of being human. (shrink)

The Oxford Handbook of Metaphysics offers the most authoritative and compelling guide to this diverse and fertile field of philosophy. Twenty-four of the world's most distinguished specialists provide brand-new essays about 'what there is': what kinds of things there are, and what relations hold among entities falling under various categories. They give the latest word on such topics as identity, modality, time, causation, persons and minds, freedom, and vagueness. The Handbook's unrivaled breadth and depth make it the definitive reference work (...) for students and academics across the philosophical spectrum. (shrink)

We ordinarily suppose that there is a difference between having and failing to exercise a rational capacity on the one hand, and lacking a rational capacity altogether on the other. This is crucial for our allocations of responsibility. Someone who has but fails to exercise a capacity is responsible for their failure to exercise their capacity, whereas someone who lacks a capacity altogether is not. However, as Gary Watson pointed out in his seminal essay ’Skepticism about Weakness of Will’, the (...) idea of an unexercised capacity is much more difficult to make sense of than it initially appears. The aim of ’Rational Capacities’ is to provide the needed explication of this idea. (shrink)

Eldred offers a remedy to the consequences of ancient Greek misconceptions of time that are also entrenched in today’s mathematized physics. Here time is spatialized as the one-dimensionally linear ‘arrow of time’ for the sake of predicting and controlling movement. But such spatialized time distorts the phenomenon of time itself. An alternative, hermeneutic-phenomenological path begins with a pre-spatial concept of time that is genuinely three-dimensional. This paves the way for recasting who we are as humans in belonging, first of all, (...) to the free openness of 3D-temporality. This belonging enables temporally 3D-vision of the psyche that empowers us to see movement at all and reconcile its inherent contradictoriness. We are then also able to conceive ourselves no longer merely as internally cogitating, self-conscious subjects, but as engaged existentially in temporally 3D-interplay, mutually estimating and esteeming who we are. This unpredictable interplay is constrained, however, by being played out in the sociating medium of thingified value, the accumulative movement of thingified value having gained the upper hand in dictating our life-movements as well as our interplay with the earth.

This will be the best way of explaining ‘Paris is the lover of Helen’, that is, ‘Paris loves, and by that very fact [et eo ipso] Helen is loved’. Here, therefore, two propositions have been brought together and abbreviated as one. Or, ‘Paris is a lover, and by that very fact Helen is a loved one’.

In this paper I debate a range of unnoticed presuppositions which are used by a selection of influential thinkers in organisation studies to adapt a theory of the irreal to the social realm. I first examine a selection of ‘Postmodern’ authors and focus on the ‘Process Metaphysics’ theories (especially those influenced by Bergson) present in excerpts of contemporary OS ‘Postmodernism’. I argue that ‘Process-Metaphysics’ is the theoretical movement which underpins these aspects of Postmodernism in organisation studies. This is evinced in (...) the writings of Chia, and Cooper which adopt a dualist view of language deployment and link this with both an anti-rationalist and anti-individualist perspective. I also examine this Postmodern thesis of Process Metaphysics in relation to its adoption of the device of the Identity Metaphor, which fastens its theories to the ‘real.’. (shrink)

Businesses interface with the natural world through rights to property. The shape of these rights and the responsibilities we assign to managers are important determinants of both patterns of resource use and pollutant levels. Consequently, conflicts have arisen between regulating bodies, indigenous groups, and corporations over the entitlements of businesses in the use of their property when that property is ecologically sensitive or significant. In this paper I develop an account of the ethical responsibilities of managers regarding their treatment of (...) the environment and their use of natural resources. This account is based on a philosophical examination of the nature of property rights. After a tour of traditional arguments employed to defend the institution of private property, I develop a new conception of property rights over objects that have a high natural resource component. I show that in today’s world, ethical concerns that motivated John Locke will yield property rights that are insufficiently strong to override a democratic say in overall use patterns and must be sensitive to factors such as need, scarcity, and the interests of stakeholders. I show a similar result for utilitarian arguments for property. On this foundation I develop a conception of property in key environmental resources that includes a stewardship element. To embody this, I suggest a set of ethical responsibilities for managers over certain natural resources that springs from it. I argue for obligations restricting harmful use patterns as a way of including the other goals (eg public participation, sustainability) that we care about, in a manner which clashes least with the liberty of owners and the efficiency of production. The outcome is a set of rights and responsibilities that take global environmental interests into account, but preserve the thrust of what is good about the institution of private property: that it rewards labour and facilitates a stable and efficient free exchange system. As a version of private property, it retains many of the advantages of global capitalism while attaching responsibilities to business decision makers. (shrink)

History is popular with health policymakers, if the regularity with which they invoke historical anecdotes to support policy change is used as an indicator. Yet the ways in which they ‘use’ history vary enormously, as does its impact. This paper explores, from the perspective of a UK academic historian, the development of ‘applied’ history in health policy. It draws on personal experience of different types and levels of engagement with policymakers, and highlights mechanisms through which this dialogue and partnership can (...) be made more efficient, effective, and intellectually rewarding for all involved.

This paper draws a correlation between the experience of consumerism portrayed in the critique of Alexander and Baudrillard and in the theory of plenitude derived from Renaissance literature. It draws parallels between features of the modern and antique sensibilities. It suggests that the e-commerce practitioner manipulates a modern economy informed by a cosmology which depicts imagery capable of interpretation in terms of conceptions derived from archaic themes. These are drawn from the High Renaissance and relate to Neoplatonism which is in (...) turn linked to Renaissance occult philosophy. Ecommerce metaphors display these aspects; and thereby both hook into, and valorise — rendering liminal — the experiential dimension of the consumer, and its incipient tensions between desire anticipated and that achieved. The article suggests how the populist magic of consumerism is not only facilitated by e-commerce but how that magic arose at a pre-modern, intellectualist level. From a philosophical perspective, readers will note the inter-relationship of earlier bodies of thought to contemporary management theories of e-commerce. Academics or practitioners interested in e-commerce or e-business are offered a fresh and radical interpretative perspective on these areas, which expresses a novel role for metaphor in terms of linking features of pre-modern and modern conceptions of reality, aslant the subjective absorption of figurative images of a textual derivation.
