Prawitz proved a theorem, formalising ‘harmony’ in Natural Deduction systems, which showed that, corresponding to any deduction there is one to the same effect but in which no formula occurrence is both the consequence of an application of an introduction rule and major premise of an application of the related elimination rule. As Gentzen ordered the rules, certain rules in Classical Logic had to be excepted, but if we see the appropriate rules instead as rules for Contradiction, then we can (...) extend the theorem to the classical case. Properly arranged there is a thoroughgoing ‘harmony’, in the classical rules. Indeed, as we shall see, they are, all together, far more ‘harmonious’ in the general sense than has been commonly observed. As this paper will show, the appearance of disharmony has only arisen because of the illogical way in which natural deduction rules for Classical Logic have been presented. (shrink)

Despite the volume of discussion on the Liar Paradox recently, there is one stream of largely British thought on the matter which is hardly represented in the wider literature. This paper points out salient aspects of the history of this tradition, from its origin in forms of propositional quantification found in Ramsey, through to more precise symbolisations which have emerged more recently. But its purpose is to exposit, with respect to a number of contested cases, the ensuing results. Thus it (...) goes on to apply the analysis to several other well known paradoxes, including one rarely discussed, which reveals more fully the consequent consistency and completeness of natural language.

A paradox is generally a puzzling conclusion we seem to be driven towards by our reasoning, but which is highly counterintuitive, nevertheless. There are, amongst these, a large variety of paradoxes of a logical nature which have teased even professional logicians, in some cases for several millennia. But what are now sometimes isolated as 'the logical paradoxes' are a much less heterogeneous collection: they are a group of antinomies centered on the notion of self-reference, some of which were known in (...) Classical times, but most of which became particularly prominent in the early decades of last century. Quine distinguished amongst paradoxes such antinomies. He did so by first isolating the 'veridical' and 'falsidical' paradoxes, which, although puzzling riddles, turned out to be plainly true, or plainly false, after some inspection. In addition, however, there were paradoxes which 'produce a self-contradiction by accepted ways of reasoning', and which, Quine thought, established 'that some tacit and trusted pattern of reasoning must be made explicit, and henceforward be avoided or revised' (Quine 1966, p7). We will first look, more broadly, and historically, at several of the main conundrums of a logical nature which have proved difficult, some since antiquity, before concentrating later on the more recent troubles with paradoxes of self-reference. They will all be called 'logical paradoxes'. (shrink)

We present a novel methodology for calculating the improvements obtained in successive versions of biomedical ontologies. The theory takes into account changes both in reality itself and in our understanding of this reality. The successful application of the theory rests on the willingness of ontology authors to document changes they make by following a number of simple rules. The theory provides a pathway by which ontology authoring can become a science rather than an art, following principles analogous to those that (...) have fostered the growth of modern evidence-based medicine. Although in this paper we focus on ontologies, the methodology can be generalized to other sorts of terminology-based artifacts, including Electronic Patient Records. (shrink)

In this accessible book, Barry Hallen discusses the major ideas, figures, and schools of thought in African philosophy. While drawing out critical issues in the formation of African philosophy, Hallen focuses on the recent scholarship, current issues, and relevant debates that have made African philosophy an important key to understanding the rich and complex cultural heritage of Africa. Hallen builds upon Africa's connections with Western philosophical traditions and explores African contributions to cultural universalism, cultural relativism, phenomenology, hermeneutics, and Marxism. (...) Hallen also examines African challenges to Western conceptions of philosophy by taking on questions such as whether philosophy can exist in cultures that are significantly based in oral traditions and what may or may not constitute philosophical texts. Among the figures whose work is discussed are Ptah-hotep, Zar'a Ya'aqob, Anton Wilhelm Amo, Paulin Hountondji, V. Y. Mudimbe, Oyeronke Oyewumi, Kwame Anthony Appiah, and Kwasi Wiredu. This clearly written, highly readable, and concise work will be essential for students and scholars of African philosophy as well as readers with a wide range of interests in African studies.

The idea that research should become more interdisciplinary has become commonplace. According to influential commentators, the unprecedented complexity of problems such as climate change or the social implications of biomedicine demand interdisciplinary efforts integrating both the social and natural sciences. In this context, the question of whether a given knowledge practice is too disciplinary, or interdisciplinary, or not disciplinary enough has become an issue for governments, research policy makers and funding agencies. Interdisciplinarity, in short, has emerged as a key political (...) preoccupation; yet the term tends to obscure as much as illuminate the diverse practices gathered under its rubric. This volume offers a new approach to theorising interdisciplinarity, showing how the boundaries between the social and natural sciences are being reconfigured. It examines the current preoccupation with interdisciplinarity, notably the ascendance of a particular discourse in which it is associated with a transformation in the relations between science, technology and society. Contributors address attempts to promote collaboration between, on the one hand, the natural sciences and engineering and, on the other, the social sciences, arts and humanities. From ethnography in the IT industry to science and technology studies, environmental science to medical humanities, cybernetics to art-science, the collection interrogates how interdisciplinarity has come to be seen as a solution not only to enhancing relations between science and society, but the pursuit of accountability and the need to foster innovation. Interdisciplinarity is essential reading for scholars, students and policy makers across the social sciences, arts and humanities, including anthropology, geography, sociology, science and technology studies and cultural studies, as well as all those engaged in interdisciplinary research. It will have particular relevance for those concerned with the knowledge economy, science policy, environmental politics, applied anthropology, ELSI research, medical humanities, and art-science.

It is plausible that there are epistemic reasons bearing on a distinctively epistemic standard of correctness for belief. It is also plausible that there are a range of practical reasons bearing on what to believe. These theses are often thought to be in tension with each other. Most significantly for our purposes, it is obscure how epistemic reasons and practical reasons might interact in the explanation of what one ought to believe. We draw an analogy with a similar distinction between (...) types of reasons for actions in the context of activities. The analogy motivates a two-level account of the structure of normativity that explains the interaction of correctness-based and other reasons. This account relies upon a distinction between normative reasons and authoritatively normative reasons. Only the latter play the reasons role in explaining what state one ought to be in. All and only practical reasons are authoritative reasons. Hence, in one important sense, all reasons for belief are practical reasons. But this account also preserves the autonomy and importance of epistemic reasons. Given the importance of having true beliefs about the world, our epistemic standard typically plays a key role in many cases in explaining what we ought to believe. In addition to reconciling (versions of) evidentialism and pragmatism, this two-level account has implications for a range of important debates in normative theory, including the interaction of right and wrong reasons for actions and other attitudes, the significance of reasons in understanding normativity and authoritative normativity, the distinction between ‘formal’ and ‘substantive’ normativity, and whether there is a unified source of authoritative normativity.

The orphaned son of an Anglican clergyman, David Hartley (1705–57) was originally destined for holy orders. Declining to subscribe to the Thirty-Nine Articles, he turned to medicine and science yet remained a religious believer. This, his most significant work, provides a rigorous analysis of human nature, blending philosophy, psychology and theology. First published in two volumes in 1749, Observations on Man is notable for being based on the doctrine of the association of ideas. It greatly influenced scientists, theologians, social (...) reformers and poets: Samuel Taylor Coleridge, who named his eldest son after Hartley, had his portrait painted while holding a copy. In Volume 1, Hartley utilises Newtonian science in his observations. He presents a theory of 'vibrations', explaining how the elements of the nerves and brain interact as a result of stimulation, creating 'associations' and emotions. (shrink)

Joseph Gikatilla's early works, composed during the 1270s, have been understood by many scholars as a fusion of Kabbalah and philosophy—an approach that he abandoned in his later compositions. This paper argues that Gikatilla's early works are in fact consistent with his later works, and that the differences between the two can be explained by the polemical engagement during his early period with Jewish philosophy and Christian missionizing. By subtly drawing Jewish students of philosophy away from Aristotelian speculation and towards (...) Kabbalah, Gikatilla sought in his early works to lay the foundation for an understanding of Judaism based on kabbalistic mytho-poesis and ecstatic mystical experience. (shrink)

A dogma of contemporary ethical theory maintains that the nature of normative support for affective attitudes is the very same as the nature of normative support for actions. The prevailing view is that normative reasons provide the support across the board. I argue that the nature of normative support for affective attitudes is importantly different from the nature of normative support for actions. Actions are indeed supported by reasons. Reasons are gradable and contributory. The support relations for affective attitudes are (...) neither. So-called reasons of the right kind for affective attitudes are facts that make those very attitudes fitting. Unlike reasons, fit-making facts for affective attitudes do not conflict with each other or combine in the explanation of further normative facts. More fit-making facts just make a more complex set of reactions fitting. This result undermines various analyses and unity theses in the philosophy of normativity. (shrink)

Barry Dainton presents a fascinating new account of the self, the key to which is experiential or phenomenal continuity. Provided our mental life continues we can easily imagine ourselves surviving the most dramatic physical alterations, or even moving from one body to another. It was this fact that led John Locke to conclude that a credible account of our persistence conditions - an account which reflects how we actually conceive of ourselves - should be framed in terms of mental (...) rather than material continuity. But mental continuity comes in different forms. Most of Locke's contemporary followers agree that our continued existence is secured by psychological continuity, which they take to be made up of memories, beliefs, intentions, personality traits, and the like. Dainton argues that that a better and more believable account can be framed in terms of the sort of continuity we find in our streams of consciousness from moment to moment. Why? Simply because provided this continuity is not lost - provided our streams of consciousness flow on - we can easily imagine ourselves surviving the most dramatic psychological alterations. Phenomenal continuity seems to provide a more reliable guide to our persistence than any form of continuity. The Phenomenal Self is a full-scale defence and elaboration of this premise. The first task is arriving at an adequate understanding of phenomenal unity and continuity. This achieved, Dainton turns to the most pressing problem facing any experience-based approach: losses of consciousness. How can we survive them? He shows how the problem can be solved in a satisfactory manner by construing ourselves as systems of experiential capacities. He then moves on to explore a range of further issues. How simple can a self be? How are we related to our bodies? Is our persistence an all-or-nothing affair? Do our minds consist of parts which could enjoy an independent existence? Is it metaphysically intelligible to construe ourselves as systems of capacities? The book concludes with a novel treatment of fission and fusion. (shrink)

Whether we're buying a pair of jeans, ordering a cup of coffee, selecting a long-distance carrier, applying to college, choosing a doctor, or setting up a 401(k), everyday decisions ; both big and small ; have become increasingly complex due to the overwhelming abundance of choice with which we are presented. As Americans, we assume that more choice means better options and greater satisfaction. But beware of excessive choice: choice overload can make you question the decisions you make before you (...) even make them, it can set you up for unrealistically high expectations, and it can make you blame yourself for any and all failures. In the long run, this can lead to decision-making paralysis, anxiety, and perpetual stress. And, in a culture that tells us that there is no excuse for falling short of perfection when your options are limitless, too much choice can lead to clinical depression. In The Paradox of Choice, Barry Schwartz explains at what point choice ; the hallmark of individual freedom and self-determination that we so cherish ; becomes detrimental to our psychological and emotional well-being. In accessible, engaging, and anecdotal prose, Schwartz shows how the dramatic explosion in choice ; from the mundane to the profound challenges of balancing career, family, and individual needs ; has paradoxically become a problem instead of a solution. Schwartz also shows how our obsession with choice encourages us to seek that which makes us feel worse. By synthesizing current research in the social sciences, Schwartz makes the counter intuitive case that eliminating choices can greatly reduce the stress, anxiety, and busyness of our lives. He offers eleven practical steps on how to limit choices to a manageable number, have the discipline to focus on those that are important and ignore the rest, and ultimately derive greater satisfaction from the choices you have to make."--provided by publisher.

International migration poses a dilemma for capitalist welfare states. This paper considers the ethical dimensions of that dilemma. It begins by addressing two questions associated with the provision of social rights for migrants: first, the extent to which differential forms of social citizenship may be associated with processes of civic stratification; second, the ambiguous nature of the economic, social and cultural rights components of the international human rights framework. It then proceeds to discuss, on the one hand, existing attempts to (...) classify or taxonomise different kinds of immigration/incorporation and welfare regime and, on the other, the different ways in which migrants may be socially constructed. Building on this analysis the paper develops an alternative taxonomy that is concerned with the different ethical premises from which the social rights of migrants may be constructed or justified. The paper concludes by applying the ideal of ?Migration without Borders? as a means to critique existing constructions of social rights. (shrink)

This paper develops the Value-Based Theory of Reasons in some detail. The central part of the paper introduces a number of theoretically puzzling features of normative reasons. These include weight, transmission, overlap, and the promiscuity of reasons. It is argued that the Value-Based Theory of Reasons elegantly accounts for these features. This paper is programmatic. Its goal is to put the promising but surprisingly overlooked Value-Based Theory of Reasons on the table in discussions of normative reasons, and to draw attention (...) to a number of areas for fruitful further research.

To Priestley, who founded his Unitarianism on the Observations, it seemed that Hartley was the greatest of human beings with the single exception of Jesus. Coleridge adopted his associationist theology in the mid 1790s, naming his eldest son David Hartley Coleridge, and passing on to Wordsworth the theory of mind that underlies 'Tintern Abbey', the (...) early Prelude and the 1800 Preface to Lyrical Ballads.

The idea of public reason is central to political liberalism's aim to provide an account of the possibility of a just and stable democratic society comprised of free and equal citizens who nonetheless are deeply divided over fundamental values. This commitment to the idea of public reason reflects the normative core of political liberalism which is rooted in the principle of democratic legitimacy and the idea of reciprocity among citizens. Yet both critics and defenders of political liberalism disagree over whether (...) or not the idea of public reason permits citizens to appeal to their comprehensive conceptions of the good in public deliberation over matters of basic justice. Our aim in this paper is to provide a defense of an exclusive idea of public reason, and at the same time we aim to dispel the underlying concerns of two prominent criticisms of the idea of public reason—the concern of alienation from the political process, as expressed by religiously oriented critics, and the concern over women's equality, as expressed by feminist critics. We argue that inclusive accounts of the idea of public reason are not consistent with political liberalism's core commitments. Further, we claim, inclusive accounts of the idea of public reason deepen feminist concerns. We think that, properly understood, an exclusive account of the idea of public reason can address feminist concerns about political liberalism and avoid alienating (reasonable) religious persons in an unacceptable way. Thus, we conclude that an exclusive account of the idea of public reason is our best hope for reconciliation. (shrink)

The truthmaker theory rests on the thesis that the link between a true judgment and that in the world to which it corresponds is not a one-to-one but rather a one-to-many relation. An analogous thesis in relation to the link between a singular term and that in the world to which it refers is already widely accepted. This is the thesis to the effect that singular reference is marked by vagueness of a sort that is best understood in supervaluationist terms. (...) In what follows we show that the supervaluationist approach to singular reference, when wedded to the truthmaker idea, yields a framework of surprising power, which offers a uniform set of solutions to a range of problems regarding identity, reference and knowledge, problems which have hitherto been dealt with on an ad hoc basis.

This book is a defense of political liberalism as a feminist liberalism. A novel and restrictive account of public reason is defended. Then it is argued that political liberalism's core commitments restrict reasonable conceptions of justice to those that secure genuine, substantive equality for women and other marginalized groups.

This article considers the implications for film analysis of the presence or absence of a manual crank. More specifically, it looks at the 16 mm Time and Motion Study Projector as used in behavioral research in the 1960s and 1970s. The controversial concept of ‘interactional synchrony’, or the dance-like coordination of people in conversation, emerged from the use of this hand-turned projector. William S. Condon developed the concept along with the technique of microanalysis. Starting with the projector manufactured by Bell (...) & Howell, he made numerous improvements to facilitate observation—‘sweeping’ over segments of very short duration to discover the rhythmic synchrony of all filmed participants. It led him to a theory of ‘process’ in communication, and in the reception of speech in particular. People always ‘danced’ to the tune of their own voice, and their listeners ‘danced’ to the tune of the speaker—at intervals of one-sixth or one-eighth of a second. This also led Condon to an epistemology of discovery derived partly from philosophy but mostly from his machinery. The universe, he said, is a ‘continuum of order’ whose structures are preserved through translations of order: of thought into speech, speech into vibrations, vibrations into neurons, and back into behavior. The only exceptions are people with disabilities, like the autistics Condon studied from the 1970s onward. But the very distinction of normal and pathological was epiphenomenal to his scanning technique; it was rooted in material and formal qualities of film and of the projector whose crank he turned often.

The appeal of materialism lies precisely in this, in its claim to be natural metaphysics within the bounds of science. That a doctrine which promises to gratify our ambition (to know the noumenal) and our caution (not to be unscientific) should have great appeal is hardly something to be wondered at. (Putnam (1983), p.210) Materialism says that all facts, in particular all mental facts, obtain in virtue of the spatio- temporal distribution, and properties, of matter. It was, as Putnam says, (...) “metaphysics within the bounds of science”, but only so long as science was thought to say that the world is made out of matter.1 In this century physicists have learned that there is more in the world than matter and, in any case, matter isn’t quite what it seemed to be. For this reason many philosophers who think that metaphysics should be informed by science advocate physicalism in place of materialism. Physicalism claims that all facts obtain in virtue of the distribution of the fundamental entities and properties –whatever they turn out to be- of completed fundamental physics. Later I will discuss a more precise formulation. But not all contemporary philosophers embrace physicalism. Some- and though a minority not a small or un-influential one- think that physicalism is rather the metaphysics for an unjustified scientism; i.e. it is scientistic metaphysics. Those among them that think that physicalism can be clearly formulated think that it characterizes a. (shrink)

Faced with the paradox of undermining futures, Humeans have resigned themselves to accounts of chance that severely conflict with our intuitions. However, such resignation is premature: The problem is Humean supervenience (HS), not Humeanism. This paper develops a projectivist Humeanism on which chance claims are understood as normative, rather than fact stating. Rationality constraints on the cotenability of norms and factual claims ground a factual-normative worlds semantics that, in addition to solving the Frege-Geach problem, delivers the intuitive set of possibilia (...) for each chance law. Hence, the account does not entail HS, and the paradox does not arise. A confirmation theory is developed, and the 'principal principle' is justified. (shrink)

Historically, philosophers have had little to say about justice and disability. However, in recent years and in response to disability rights movements, philosophers have started to consider the claims to justice of persons with mental and physical impairments. Importantly, some have charged that without extensive revision, social contract accounts of justice – which enjoy immense popularity among political philosophers – cannot address the needs and interests of persons with disabilities. In this article, I explain why social contract accounts are thought (...) to flounder when it comes to justice for persons with disabilities. Then I assess the merits of recent attempts to construct theories of justice inclusive of persons with disabilities. In particular, I consider Nussbaum’s capabilities approach, Kittay’s justice as caring, and various restatements of the social contract. (shrink)

Henri Bergson (1859-1941) was once the most famous philosopher in the world, but his reputation waned in the latter half of the 20th century. Barry Allen here makes the case for Bergson as a great philosopher, one whose thought has much to contribute to contemporary philosophical questions. Living in Time presents chapters on each of Bergson's four major works, explaining his theories of time, perception, memory, and panpsychic consciousness, his innovative concept of virtual existence, his objection to Darwin, his (...) controversy with Einstein, his philosophy of creative evolution, and his social philosophy of closed and open society. In particular Allen focusses on Bergson's powerful ideas on time. Classical arguments for determinism fallaciously apply spatial concepts to consciousness; once we take time seriously, which means acknowledging its reality as duration and its difference from space, Bergson showed that the arguments for determinism become insupportable. Bergson's ideas on time and evolution offer a comparison with Nietzsche, which Allen develops, exposing both philosophical concurrence and systematic difference. The book's conclusion discusses the question of Bergson and naturalism and summarizes the ontology of the virtual that emerges as a core part of Bergson's thought. (shrink)

We argue that a particular approach to satisfying the broad predictive ambitions of the sciences demands law confirmation. On this approach we confirm non-nomic generalizations by confirming there are no actually realized ways of causing disconfirming cases. This gives causal generalizations a crucial role in prediction. We then show how rational judgements of relevant causal similarity can be used to confirm that causal generalizations themselves have no actual disconfirmers, providing a distinctive and clearly viable methodology for inductively confirming them. Finally, (...) we argue that for agents in our epistemic position using this methodology to confirm causal generalizations of adequate breadth will commonly demand law confirmation. We make a prima facie assessment of the methodology’s fit with scientific practice and briefly consider the prospects for an associated analysis of laws. (shrink)

We use normative reasons in a bewildering variety of different ways. And yet, as many recent theorists have shown, one can discern systematic distinctions underlying this complexity. This paper is a contribution to this project of constructive normative metaphysics. We aim to bring a black sheep back into the flock: the balancing model of weighing reasons. This model is threatened by a variety of cases in which distinct reasons overlap, in the sense that they do not contribute separate weight for (...) or against an option. Our response is to distinguish between derivative reasons and load-bearing reasons, only the latter of which contribute non-overlapping weight to an option. This distinction is close at hand for analyses of reasons in terms of the promotion of significant outcomes. But we also develop an account of this distinction for fundamentalist theories of normative reasons. (shrink)

A novel motivation for a Humean projectivist construal of our concept of scientific law is provided. The analysis is partially developed and used to explain intuitions that are problematic for a Humean reductionist construal of lawhood. A possible non-Humean rejoinder is discussed and rejected. In an appendix, further intuitions that are problematic for Humean reductionists are explained projectively.
