Kevin Scharp proposes an original theory of the nature and logic of truth on which truth is an inconsistent concept that should be replaced for certain theoretical purposes. He argues that truth is best understood as an inconsistent concept, and proposes a detailed theory of inconsistent concepts that can be applied to the case of truth. Truth also happens to be a useful concept, but its inconsistency inhibits its utility; as such, it should be replaced with consistent concepts that (...) can do truth's job without giving rise to paradoxes. To this end, Scharp offers a pair of replacements, which he dubs ascending truth and descending truth, along with an axiomatic theory of them and a new kind of possible-worlds semantics for this theory. He goes to develop Davidson's idea that truth is best understood as the core of a measurement system for rational phenomena, and offers a semantic theory that treats truth predicates as assessment-sensitive and solves the problems posed by the liar and other paradoxes.

We are grateful to the commentators for taking the time to respond to our article. Too many interesting and important points have been raised for us to tackle them all in this response, and so in the below we have sought to draw out the major themes. These include problems with both the term ‘ultimate causation’ and the proximate-ultimate causation dichotomy more generally, clarification of the meaning of reciprocal causation, discussion of issues related to the nature of development and phenotypic (...) plasticity and their roles in evolution, and consideration of the need for an extended evolutionary synthesis.

Bayesian reasoning has been applied formally to statistical inference, machine learning and analysing scientific method. Here I apply it informally to more common forms of inference, namely natural language arguments. I analyse a variety of traditional fallacies, deductive, inductive and causal, and find more merit in them than is generally acknowledged. Bayesian principles provide a framework for understanding ordinary arguments which is well worth developing.

The Lottery Paradox has been thought to provide a reductio argument against probabilistic accounts of inductive inference. As a result, much work in artificial intelligence has concentrated on qualitative methods of inference, including default logics, which are intended to model some varieties of inductive inference. It has recently been shown that the paradox can be generated within qualitative default logics. However, John Pollock's qualitative system of defeasible inference, does avoid the Lottery Paradox by incorporating a rule designed specifically for that (...) purpose. I shall argue that Pollock's system instead succumbs to a worse disease: it fails to allow for induction at all. (shrink)

In this paper a look is taken at the relatively new area of culturing neural tissue and embodying it in a mobile robot platform—essentially giving a robot a biological brain. Present technology and practice is discussed. New trends and the potential effects of and in this area are also indicated. This has a potential major impact with regard to society and ethical issues and hence some initial observations are made. Some initial issues are also considered with regard to the potential (...) consciousness of such a brain. (shrink)

ABSTRACT In a series of papers read to the Cambridge Philosophical Society through the 1820s, the Cambridge mathematician George Peacock laid the foundation for a natural history of arithmetic that would tell a story of human progress from counting to modern arithmetic. The trajectory of that history, Peacock argued, established algebraic analysis as a form of universal reasoning that used empirically warranted operations of mind to think with symbols on paper. The science of counting would suggest arithmetic, arithmetic would suggest (...) arithmetical algebra, and, finally, arithmetical algebra would suggest symbolic algebra. This philosophy of suggestion provided the foundation for Peacock's “principle of equivalent forms,” which justified the practice of nineteenth-century English symbolic algebra. Peacock's philosophy of suggestion owed a considerable debt to the early Cambridge Philosophical Society culture of natural history. The aim of this essay is to show how that culture of natural history was constitutively significant to the practice of nineteenth-century English algebra. (shrink)

I have applied a fairly general, learning theoretic perspective to some questions raised by Reichenbach's positions on induction and discovery. This is appropriate in an examination of the significance of Reichenbach's work, since the learning-theoretic perspective is to some degree part of Reichenbach's reliabilist legacy. I have argued that Reichenbach's positivism and his infatuation with probabilities are both irrelevant to his views on induction, which are principally grounded in the notion of limiting reliability. I have suggested that limiting reliability is (...) still a formidable basis for the formulation of methodological norms, particularly when reliability cannot possibly be had in the short run, so that refined judgments about evidential support must depend upon measure-theoretic choices having nothing to do in the short run with the truth of the hypothesis under investigation. To illustrate the generality of Reichenbach's program, I showed how it can be applied to methods that aim to solve arbitrary assessment and discovery problems in various senses. In this generalized Reichenbachian setting, we can characterize the intrinsic complexity of reliable inductive inference in terms of topological complexity. Finally, I let Reichenbach's theory of induction have the last say about hypothetico-deductive method. (shrink)

Emerging cybertechnologies, such as social digibots, bend epistemological conventions of life and culture already complicated by human and animal relationships. Virtually-augmented niches of machines and organic life promise new free-energy-governed selection of intelligent digital life. These provocative eco-evolutionary contexts demand a theory of (natural and artificial) minds to characterize and validate the immersive social phenomena universally-shaping cultural affordances.

Wittgenstein was centrally concerned with the puzzling nature of the mind, mathematics, morality and modality. He also developed innovative views about the status and methodology of philosophy and was explicitly opposed to crudely "scientistic" worldviews. His later thought has thus often been understood as elaborating a nuanced form of naturalism appealing to such notions as "form of life", "primitive reactions", "natural history", "general facts of nature" and "common behaviour of mankind". And yet, Wittgenstein is strangely absent from much of the (...) contemporary literature on naturalism and naturalising projects. This is the first collection of essays to focus explicitly on the relationship between Wittgenstein and naturalism. The volume is divided into four sections, each of which addresses a different aspect of naturalism and its relation to Wittgenstein's thought. The first section considers how naturalism could or should be understood. The second section deals with some of the main problematic domains—consciousness, meaning, mathematics—that philosophers have typically sought to naturalise. The third section explores ways in which the conceptual nature of human life might be continuous in important respects with animals. The final section is concerned with the naturalistic status and methodology of philosophy itself. This book thus casts a fresh light on many classical philosophical issues and brings Wittgensteinian ideas to bear on a number of current debates-for example experimental philosophy, neo-pragmatism and animal cognition/ethics-in which naturalism is playing a central role.

We further develop the mathematical theory of causal interventions, extending earlier results of Korb, Twardy, Handfield, & Oppy, (2005) and Spirtes, Glymour, Scheines (2000). Some of the skepticism surrounding causal discovery has concerned the fact that using only observational data can radically underdetermine the best explanatory causal model, with the true causal model appearing inferior to a simpler, faithful model (cf. Cartwright, (2001). Our results show that experimental data, together with some plausible assumptions, can reduce the space of viable explanatory (...) causal models to one. (shrink)

A finite data set is consistent with infinitely many alternative theories. Scientific realists recommend that we prefer the simplest one. Anti-realists ask how a fixed simplicity bias could track the truth when the truth might be complex. It is no solution to impose a prior probability distribution biased toward simplicity, for such a distribution merely embodies the bias at issue without explaining its efficacy. In this note, I argue, on the basis of computational learning theory, that a fixed simplicity bias (...) is necessary if inquiry is to converge to the right answer efficiently, whatever the right answer might be. Efficiency is understood in the sense of minimizing the least fixed bound on retractions or errors prior to convergence. (shrink)

In this paper, I examine the terms on which John Simmons rejects all arguments for a moral obligation to obey the law and so defends “philosophical anarchism.” Although I accept his rejection of several criteria on which others might and often do insist, I criticize his reliance on the conditions of “generality” and “particularity.” In doing so, I propose an alternative to his influential conception of legitimacy.

This research contributes to emergent theories on subject formation by showing how community garden participants in a small rural town in Northern Peru came to embrace a set of ideas and practices related to organic agriculture. Most CG scholarship describes the myriad benefits for participants and their communities, as well as individuals’ motivations for wanting to grow their own food. Relatively little research has explored how various kinds of gardens and their organizers produce subjects. Drawing from scholarship on community gardens (...) and subject formation, I examine the emergence of what I call an “organic subjectivity” among garden participants. Based on interviews and fieldwork conducted in Peru, I argue that the making of organic subjects in the CG is the result of three primary influences: the changing agrarian context in the community marked by the adoption of conventional farming practices, the influence of the garden organizer as the agent of an organic ideology, and the material practices associated with CG participation. This case study reinforces the notion that CGs produce subjects and that such subjects could well be oriented towards an agenda of progressive agrarian change that promotes environmental awareness and ecological farming practices, key elements of emerging alternative food networks in the global North and South.

Kevin Gray,Kafumu Kalyalya | : In this paper we challenge the role of consent in the global order by discussing current modes of international law making in the global order. We contend that the features of state consent in international law depart substantially from those assumed by theorists of the liberal order, who subscribe, in most cases, to the realist conception of state action. We argue, against those theorists, that state consents to coercive measures, and the state’s role in (...) carrying them out, has ceased to be central to an account of global law. We conclude that international law—often thought of as law beyond the state—now has expanded its scope to reach individuals and corporations, and that this change has important ramifications for theories of global justice. | : Dans cet article, nous interrogeons le rôle de l’accord dans l’ordre global en discutant les modes courants de constitution des lois internationales au sein de cet ordre. Nous prétendons que les fonctions de l’accord étatique en loi internationale s’écartent substantiellement de celles assumées par les théoriciens de l’ordre libéral, qui souscrivent, dans la plupart des cas, à la conception réaliste de l’action étatique. Contre ces théoriciens, nos posons que l’État consent à des mesures coercitives, et que le rôle de l’État d’effectuer celles-ci a cessé d’être central dans l’explication de la loi globale. Nous concluons que la loi internationale – souvent pensée comme une loi hors de l’État – a maintenant étendu son spectre jusqu’aux individus et corporations, et que ce changement a d’importantes ramifications que les théories globales de la justice devraient considérer.

Intensive care units are challenging and technologically advanced environments. Dealing with situations that have an ethical dimension is an intrinsic part of working in such a milieu. When a moral dilemma emerges, it can cause anxiety and unease for all staff involved with it. Theoretical and abstract papers reveal that having to confront situations of ethical difficulty is a contributory factor to levels of poor morale and burnout among critical care staff. Despite this, there is a surprising dearth of published (...) nursing research in the UK that investigates how staff deal with ethical issues in intensive care units. The purpose of this paper is to explore and discuss the development of a research framework designed to explore how staff deal with moral dilemmas in a British inten sive care unit. (shrink)

This essay explores Thomas Browne's Pseudodoxia epidemica, with its lengthy book on 'errors' in animal lore. In the limited critical literature on Browne's natural history, this author is generally seen as stumbling towards a zoological idiom and clearing away the emblematic 'clutter' of earlier writers on natural history—Gesner, Aldrovandi, Topsell or Franzius. This essay proposes that Browne is working with a more complex set of co-ordinates in his thought, beyond his experimental inclinations and his Aristotelian assumptions. It will explore the (...) extent to which his studies of animals emerge from, and duplicate, the presumptions of his biblical hermeneutics, and it will suggest that Browne regularly exports terms from scriptural exegesis—the categories of the literal, the figurative, and the emblematic—into his investigations of the natural world.

This article is based on an analysis of two types of argument, called utilitarian and educational respectively, which are commonly used to justify the teaching of modern/foreign languages in schools. Serious flaws are identified in the utilitarian arguments often employed to defend the teaching of modern languages and different educational arguments which might be offered as justification for their inclusion in the school curriculum are distinguished and appraised. The paper concludes with a consideration of the implications of the foregoing analysis (...) for the place of modern languages in the school curriculum. (shrink)

Presburger arithmetic is the first-order theory of the natural numbers with addition. We characterize sets that can be defined by a Presburger formula as exactly the sets whose characteristic functions can be represented by rational generating functions; a geometric characterization of such sets is also given. In addition, ifp= are a subset of the free variables in a Presburger formula, we can define a counting functiong to be the number of solutions to the formula, for a givenp. We show that (...) every counting function obtained in this way may be represented as, equivalently, either a piecewise quasi-polynomial or a rational generating function. Finally, we translate known computational complexity results into this setting and discuss open directions. (shrink)

This article examines Śāntarakṣita’s and Kamalaśīla’s understandings of svatantra and prasaṅga proofs in the attempt to clarify how and why Tibetan Prāsaṅgikas came to portray svatantra inference as an instance of the very thing Madhyamaka rejects. The article proceeds in four parts. A brief comparison of Patsap Nyimadrak’s portrayal of svatantra inference with Bhāviveka’s and Candrakīrti’s employment of this expression shows that Patsap expanded the meaning of it, charging its users with embracing a realism at odds with Madhyamaka emptiness. Patsap’s (...) arguments against Śāntarakṣita’s “neither one nor many” proof lead us consider the latter’s and Kamalaśīla’s understanding of svatantra and prasaṅga proofs, which turns out to be consistent with, if more sophisticated than, Bhāviveka’s and Candrakīrti’s usage. An exploration of Kamalaśīla’s development of the proof of the naturelessness of all things, real and imagined, calls into question the svatantra-prasaṅga distinction but still leaves us without a source for Patsap’s characterization. A consideration of Śāntarakṣita’s and Kamalaśīla’s use of svatantra to characterize Mīmāṃsā conceptions of an authorless Veda and “intrinsic validity,” as well as their own view of “self-awareness,” offers potential sources for characterizing valid cognition and, by extension, inference as “autonomous.”.

Some think of art as opposed to philosophy and science, and indeed sometimes opposed to morality. Here, Wall explores the fundamental ways of pursuing aesthetics, speculation, science, mathematics, and morality. Conceptually these are not opposed. He illustrates the ideas with reference to an array of ancient and modern thinkers.

'This volume will make a lasting contribution to how we address the dilemmas that human rights theory and practice encounter - for instance, between democracy and human rights, negative and positive rights, or individual and group rights. Philosophers have become indispensable to lawyers' arguments about why human rights matter, and how they must be interpreted: this book superbly illustrates why.' - Olivier De Schutter, University of Louvain, Belgium and United Nations Special Rapporteur on the right to food.

This paper concerns automorphisms of the computably enumerable sets. We prove two results relating semilow sets and prompt degrees via automorphisms, one of which is complementary to a recent result of Downey and Harrington. We also show that the property of effective simplicity is not invariant under automorphism, and that in fact every promptly simple set is automorphic to an effectively simple set. A major technique used in these proofs is a modification of the Harrington-Soare version of the method of (...) Harrington-Soare and Cholak for constructing Δ 0 3 automorphisms; this modification takes advantage of a recent result of Soare on the extension of "restricted" automorphisms to full automorphisms.

Bioethics evolved from traditional physician ethics and theological ethics. It has become important in contemporary discussions of Medicine and ethics. But in contemporary secular societies the foundations of bioethics are minimal in their content and often rely on procedural ethics. The bioethics of particular communities, particularly religious communities, are richer than the procedural ethics of a secular society. Religious bioethics, situated within religious communities, are richer in content in general and in the lived reality.
