(1994). The correspondence between James Hutton (1726–1797) and James Watt (1736–1819) with two letters from Hutton to George Clerk-Maxwell (1715–1784): Part I. Annals of Science: Vol. 51, No. 6, pp. 637-653.

There are eleven previously unpublished letters between James Hutton and James Watt in the Doldowlod collection, which Birmingham City Archives acquires from Lord Gibson-Watt in 1994. They were written between 1774 and 1795. Very little of Hutton's other correspondence survives, so these letters add significantly to our knowledge. The earliest letters together with two letters from Hutton to George Clerk-Maxwell , describe geological tours that Hutton made through Wales, the Midlands, and the south-west of England in 1774. The (...) correspondence after 1774 reveals Watt's expertise in geology, and also discusses meteorology, varnish making, Symington's steam engines, the first experiments with steam navigation, pneumatic medicine, and other topics.

Limited Aggregation is the view that when there are competing moral claims that demand our attention, we should sometimes satisfy the largest aggregate of claims, depending on the strength of the claims in question. In recent years, philosophers such as Patrick Tomlin and Alastair Norcross have argued that Limited Aggregation violates a number of rational choice principles such as Transitivity, Separability, and Contraction Consistency. Current versions of Limited Aggregation are what may be called Comparative Approaches because they involve assessing the (...) relative strengths of various claims. In this paper, we offer a non-comparative version of Limited Aggregation, what we call the Threshold Approach. It states that there is a non-relative threshold that separates various claims. We demonstrate that the Threshold Approach does not violate rational choice principles such as Transitivity, Separability, and Contraction Consistency, and we show that potential concerns regarding such a view are surmountable.

In lieu of an abstract, here is a brief excerpt of the content:RELIGION AND SYMBOLIC VIOLENCE Paul Ricoeur Université de Nanterre Paris X These are issues that I take very much to heart, so I will risk my own thoughts on the relation between religion and violence, not excluding the violence in and ofreligion. This is to say that I am not evading the objection made by Jean-Pierre Changeux in a recent discussion, namely, that religion as such produces violence. I (...) do not wish to evade the objection nor to hide behind the collateral explanation that it is when religion is detoured by politics that it produces violence. It is the presupposition that religion produces violence that brings me into discussion with René Girard. I encountered his work several decades ago and I have met him intermittently, with moments of distancing and rediscovery. This is the case for me again today regarding one of his later books, The Scapegoat. I cannot forget the dazzling excitement of 1972 when Violence and the Sacred first appeared. And then for me came a moment of hesitation, of doubt: isn't this explanation too psychologizing? Aren't the Gospels too easily exonerated ofthe accusation ofviolence? But I thereafter experienced disappointment with alternative accounts, principally sociological ones, and in particular with the one given by Maurice Bloch in La Violence du religieux. I am going to take the risk of a personal interpretation ofthe intimate relation between religion and violence. My own conviction, at bottom, is that I have been able, by broadening and deepening the issue, to discern the point where this very movement of going deeper bifurcates and branches out toward external violence. I have clarified my position in La Critique et la conviction and in my more recent debate with J.R Changeux, Ce quifait que nouspensons on this complicity between religion and violence. And it was in pursuing the direction opened up in La Critique et la conviction that I rediscovered an 2 Paul Ricoeur interest in The Scapegoat. I found his interpretation not only to be complementary to my own, but its necessary complement. I will now proceed to show how René Girard's thesis is necessary to my own thinking. So now I will go directly to my interpretive proposal, then I will turn to the position of Bloch in La Violence du religieux, a sociological interpretation, in order to come back in the end to Girard. It is by way of reflection on tolerance considered as a progressive initiation that I arrived at the interpretation I am going to present. At its minimal state, we find only the tolerance ofthe intolerant person, who states, "I don't agree with what you believe, I disapprove of it, but I cannot prevent it. I tolerate it in the sense of not being able to prevent it; I would like to prevent it, but I do not have the power to do so." At a second level, tolerance is more positive, saying, "I maintain the conviction that I am the one who has the truth, but I recognize, by way of being accommodating, that you have the right to profess what I hold as false, and I do this in the name ofjustice. That is to say, you certainly have the right, and it is one equal to mine, to profess what you believe, although I take it as false." I would say that the force of the principle ofjustice as thus expressed is this: any other life is worth as much as mine. Let us say that what I recognize here is the right to error. But at this stage I am torn within by the truth that I believe to be unilaterally mine and the justice that entails recognition ofthe other, which I place on another level from that oftruth. I make a further step in pursuing the issue, at a level farther advanced, when I say, "My adversary has perhaps a part ofthe truth but I don't know what it is." I would say that this is the perspectival version oftolerance: the other person sees a side of things, which I cannot see. But our positions cannot be substituted for each other. At this stage there is a... (shrink)

In a challenge to Basic Emotion theories, Ortony suggested in a recent article that the existence of affect-free surprise means that surprise is not necessarily valenced and therefore arguably not an emotion. In an article in response, Neta and Kim argued that surprise is always valenced and therefore is an emotion, with apparent cases of affect-free surprise actually being cases of the cognitive state of unexpectedness rather than surprise. We view Neta and Kim's position as resting on an idiosyncratic stipulation (...) of word usage. We further suggest that rejecting affect-free surprise by appealing to examples of affect-laden surprise has no bearing on whether surprise is always valenced, and propose that when surprise appears to be affect-laden the locus of the experienced valence is a co-occurring emotion.

Biodiversity is a valuable resource that supports sustainability within agricultural systems, yet in contradiction to this agriculture is recognised as a contributor to biodiversity loss. Agricultural advisory services are institutions that support sustainable agricultural development, employing a variety of approaches including farmer discussion groups in doing so. This study evaluates the impact of a farmland biodiversity management (FBM) communication strategy piloted within Irish farmer discussion groups. A sensemaking lens was applied in this objective to gain an understanding of how this (...) strategy could create an actionable space for FBM promotion amongst farmers. The strategy was piloted with six Irish dairy farmer discussion groups, after which focus groups were conducted with members of these groups. Additionally, baseline and endline surveys were completed by the members to determine their knowledge, attitude and on-farm practices relating to FBM. Analysis of the focus group data identified that the communication strategy supported the affordance of sensemaking with respect to FBM. Analysis of the data from the baseline and endline surveys relating to knowledge, attitudes and practices found that engaging with the communication strategy promoted farmers to improve their attitude in relation to FBM. Results from this study provide important lessons for agricultural advisory services to support farmers in incorporating FBM into the overall management of their farms and, in turn, to promote the improvement of farmland biodiversity and contribute to a sustainable future.

A History of Scottish Philosophy is a series of collaborative studies by expert authors, each volume being devoted to a specific period. Together they provide a comprehensive account of the Scottish philosophical tradition, from the centuries that laid the foundation of the remarkable burst of intellectual fertility known as the Scottish Enlightenment, through the Victorian age and beyond, when it continued to exercise powerful intellectual influence at home and abroad. The books aim to be historically informative, while at the same (...) time serving to renew philosophical interest in the problems with which the Scottish philosophers grappled and in the solutions they proposed. This is a companion volume to Scottish Philosophy in the Eighteenth Century, Volume I. Where Volume I covered Scottish Enlightenment contributions to morals, politics, art, and religion, this second volume covers philosophical method, metaphysics, and the philosophy of mind. It includes a comprehensive account of the teaching of philosophy in Scottish universities in the eighteenth century. Particular attention is given to Scottish achievements in the science of the mind in chapters on perception, the intellectual powers, the active powers, habit and the association of ideas, and language.

From Bishop Wilberforce in the 1860s to the advocates of "creation science" today, defenders of traditional mores have condemned Darwin's theory of evolution as a threat to society's values. Darwin's defenders, like Stephen Jay Gould, have usually replied that there is no conflict between science and religion--that values and biological facts occupy separate realms. But as James Rachels points out in this thought-provoking study, Darwin himself would disagree with Gould. Darwin, who had once planned on being a clergyman, was (...) convinced that natural selection overthrew our age-old religious beliefs. Created from Animals offers a provocative look at how Darwinian evolution undermines many tenets of traditional philosophy and religion. James Rachels begins by examining Darwin's own life and work, presenting an astonishingly vivid and compressed biography. We see Darwin's studies of the psychological links in evolution (such as emotions in dogs, and the "mental powers" of worms), and how he addressed the moral implications of his work, especially in his concern for the welfare of animals. Rachels goes on to present a lively and accessible survey of the controversies that followed in Darwin's wake, ranging from Herbert Spencer's Social Darwinism to Edward O. Wilson's sociobiology, and discusses how the work of such influential intellects as Descartes, Hume, Kant, T.H. Huxley, Henri Bergson, B.F. Skinner, and Stephen Jay Gould has contributed to--or been overthrown by--evolutionary science. Western philosophy and religion, Rachels argues, have been shaken by the implications of Darwin's work, most notably the controversial idea that humans are simply a more complex kind of animal. Rachels assesses a number of studies that suggest how closely humans are linked to other primates in behavior, and then goes on to show how this idea undercuts the work of many prominent philosophers. Kant's famous argument that suicide reduces one to the level of an animal, for instance, is meaningless if humans are, in fact, animals. Indeed, humanity's membership in the animal kingdom calls into question the classic notions of human dignity and the sacredness of human life. What we need now, Rachels contends, is a philosophy that does not discriminate between different species, one that addresses each being on an individual basis. With this sweeping survey of the arguments, the philosophers, and the deep implications surrounding Darwinism, Rachels lays the foundations for a new view of morality. Vibrantly written and provocatively argued, Created from Animals offers a new perspective on issues ranging from suicide to euthanasia to animal rights. (shrink)

Łukasiewicz implication algebras are {→,1}-subreducts of Wajsberg algebras (MV-algebras). They are the algebraic counterpart of Super-Łukasiewicz Implicational logics investigated in Komori, Nogoya Math J 72:127–133, 1978. The aim of this paper is to study the direct decomposability of free Łukasiewicz implication algebras. We show that freely generated algebras are directly indecomposable. We also study the direct decomposability in free algebras of all its proper subvarieties and show that infinitely freely generated algebras are indecomposable, while finitely free generated algebras can be (...) only decomposed into a direct product of two factors, one of which is the two-element implication algebra.

Former Google advertising strategist, now Oxford-trained philosopher James Williams launches a plea to society and to the tech industry to help ensure that the technology we all carry with us every day does not distract us from pursuing our true goals in life. As information becomes ever more plentiful, the resource that is becoming more scarce is our attention. In this 'attention economy', we need to recognise the fundamental impacts of our new information environment on our lives in order (...) to take back control. Drawing on insights ranging from Diogenes to contemporary tech leaders, Williams's thoughtful and impassioned analysis is sure to provoke discussion and debate. Williams is the inaugural winner of the Nine Dots Prize, a new Prize for creative thinking that tackles contemporary social issues. This title is also available as Open Access. (shrink)

Conformity is an often criticized feature of human belief formation. Although generally regarded as a negative influence on reliability, it has not been widely studied. This paper attempts to determine the epistemic effects of conformity by analyzing a mathematical model of this behavior. In addition to investigating the effect of conformity on the reliability of individuals and groups, this paper attempts to determine the optimal structure for conformity. That is, supposing that conformity is inevitable, what is the best way for (...) conformity effects to occur? The paper finds that in some contexts conformity effects are reliability inducing and, more surprisingly even when it is counterproductive, not all methods for reducing its effect are helpful. These conclusions contribute to a larger discussion in social epistemology regarding the effect of social behavior on individual reliability. (shrink)

In this book, James Gordon Finlayson examines the Habermas-Rawls debate in context and considers its wider implications. He traces their dispute from its inception in their earliest works to the 1995 exchange and its aftermath, as well as its legacy in contemporary debates. Finlayson discusses Rawls’s Political Liberalism and Habermas’s Between Facts and Norms, considering them as the essential background to the dispute and using them to lay out their different conceptions of justice, politics, democratic legitimacy, individual rights, and (...) the normative authority of law. He gives a detailed analysis and assessment of their contributions, assessing the strengths and weaknesses of their different approaches to political theory, conceptions of democracy, and accounts of religion and public reason, and he reflects on the ongoing significance of the debate. The Habermas-Rawls Debate is an authoritative account of the crucial intersection of two major political theorists and an explication of why their dispute continues to matter. (shrink)

Ludwig Wittgenstein's _Tractatus Logico-Philosophicus_ and _Philosophical Investigations_ are among the most influential philosophical books of the twentieth century, and also among the most perplexing. Wittgenstein warned again and again that he was not and would not be understood. Moreover, Wittgenstein's work seems to have little relevance to the way philosophy is done today. In _Wittgenstein in Exile_, James Klagge proposes a new way of looking at Wittgenstein -- as an exile -- that helps make sense of this. Wittgenstein's exile (...) was not, despite his wanderings from Vienna to Cambridge to Norway to Ireland, strictly geographical; rather, Klagge argues, Wittgenstein was never at home in the twentieth century. He was in exile from an earlier era -- Oswald Spengler's culture of the early nineteenth century. Klagge draws on the full range of evidence, including Wittgenstein's published work, the complete Nachlaß, correspondence, lectures, and conversations. He places Wittgenstein's work in a broad context, along a trajectory of thought that includes Job, Goethe, and Dostoyevsky. Yet Klagge also writes from an analytic philosophical perspective, discussing such topics as essentialism, private experience, relativism, causation, and eliminativism. Once we see Wittgenstein's exile, Klagge argues, we will gain a better appreciation of the difficulty of understanding Wittgenstein and his work. (shrink)

Democracy establishes relationships of political equality, ones in which citizens equally share authority over what they do together and respect one another as equals. But in today's divided public square, democracy is challenged by political thinkers who disagree about how democratic institutions should be organized, and by antidemocratic politicians who exploit uncertainties about what democracy requires and why it matters. Democratic Equality mounts a bold and persuasive defense of democracy as a way of making collective decisions, showing how equality of (...) authority is essential to relating equally as citizens. James Lindley Wilson explains why the US Senate and Electoral College are urgently in need of reform, why proportional representation is not a universal requirement of democracy, how to identify racial vote dilution and gerrymandering in electoral districting, how to respond to threats to democracy posed by wealth inequality, and how judicial review could be more compatible with the democratic ideal. What emerges is an emphatic call to action to reinvigorate our ailing democracies, and a road map for widespread institutional reform. Democratic Equality highlights the importance of diverse forms of authority in democratic deliberation and electoral and representative processes—and demonstrates how that authority rests equally with each citizen in a democracy.

An essay review of Joseph Harris, "Misanthropy in the Age of Reason".

John Locke's theory of property is perhaps the most distinctive and the most influential aspect of his political theory. In this book James Tully uses an hermeneutical and analytical approach to offer a revolutionary revision of early modern theories of property, focusing particularly on that of Locke. Setting his analysis within the intellectual context of the seventeenth century, Professor Tully overturns the standard interpretations of Locke's theory, showing that it is not a justification of private property. Instead he shows (...) it to be a theory of individual use rights within a framework of inclusive claim rights. He links Locke's conception of rights not merely to his ethical theory, but to the central arguments of his epistemology, and illuminates the way in which Locke's theory is tied to his metaphysical views of God and man, his theory of revolution and his account of a legitimate polity.

The purpose of this paper is to explore three alternative frameworks for understanding the nature of language and mentality, which accent syntactical, semantical, and pragmatical aspects of the phenomena with which they are concerned, respectively. Although the computational conception currently exerts considerable appeal, its defensibility appears to hinge upon an extremely implausible theory of the relation of form to content. Similarly, while the representational approach has much to recommend it, its range is essentially restricted to those units of language that (...) can be understood in terms of undefined units. Thus, the only alternative among these three that can account for the meaning of primitive units of language is one emphasizing the basic role of skills, habits, and tendencies in relating signs and dispositions.

What do the rules of logic say about the meanings of the symbols they govern? In this book, James W. Garson examines the inferential behaviour of logical connectives, whose behaviour is defined by strict rules, and proves definitive results concerning exactly what those rules express about connective truth conditions. He explores the ways in which, depending on circumstances, a system of rules may provide no interpretation of a connective at all, or the interpretation we ordinarily expect for it, or (...) an unfamiliar or novel interpretation. He also shows how the novel interpretations thus generated may be used to help analyse philosophical problems such as vagueness and the open future. His book will be valuable for graduates and specialists in logic, philosophy of logic, and philosophy of language. (shrink)

A novel account of virtue signaling and what makes it bad has recently been offered by Justin Tosi and Brandon Warmke. Despite plausibly vindicating the folk’s conception of virtue signaling as a bad thing, their account has recently been attacked by both Neil Levy and Evan Westra. According to Levy and Westra, virtue signaling actually supports the aims and progress of public moral discourse. In this paper, we rebut these recent defenses of virtue signaling. We suggest that virtue signaling only (...) supports the aims of public moral discourse to the extent it is an instance of a more general phenomenon that we call norm signaling. We then argue that, if anything, virtue signaling will undermine the quality of public moral discourse by undermining the evidence we typically rely on from the testimony and norm signaling of others. Thus, we conclude, not only is virtue signaling not needed, but its epistemological effects warrant its bad reputation. (shrink)

Throughout his career, Deleuze developed a series of original philosophies of time and applied them successfully to many different fields. Now James Williams presents Deleuze's philosophy of time as the central concept that connects his philosophy as a whole. Through this conceptual approach, the book covers all the main periods of Deleuze's philosophy: the early studies of Hume, Nietzsche, Kant, Bergson and Spinoza, the two great philosophical works, Difference and Repetition and Logic of Sense, the Capitalism and Schizophrenia works (...) with Guattari, and the late influential studies of literature, film and painting.The result is an important reading of Deleuze and the first full interpretation of his philosophy of time.

Through an ambitious and critical revision of Michel Foucault's investigation of ethics, James Faubion develops an original program of empirical inquiry into the ethical domain. From an anthropological perspective, Faubion argues that Foucault's specification of the analytical parameters of this domain is the most productive point of departure in conceptualizing its distinctive features. He further argues that Foucault's framework is in need of substantial revision to be of genuinely anthropological scope. In making this revision, Faubion illustrates his program with (...) two extended case studies: one of a Portuguese marquis and the other of a dual subject made up of the author and a millenarian prophetess. The result is a conceptual apparatus that is able to accommodate ethical pluralism and yield an account of the limits of ethical variation, providing a novel resolution of the problem of relativism that has haunted anthropological inquiry into ethics since its inception.

This reading makes connections to his ground-breaking work on literature, to his critical but also progressive relation to the sciences, and to (...) his controversial denial of the priority of standard logics, human values and 'meaning' in thinking.This book will open new debates and develop current ones around Deleuze's work in philosophy, politics, literature, linguistics, cultural studies and sociology.

The ancient philosophical school of Epicureanism tried to argue that death is "nothing to us." Were they right? James Warren provides a comprehensive study and articulation of the interlocking arguments against the fear of death found not only in the writings of Epicurus himself, but also in Lucretius' poem De rerum natura and in Philodemus' work De morte. These arguments are central to the Epicurean project of providing ataraxia (freedom from anxiety) and therefore central to an understanding of Epicureanism (...) as a whole. They also offer significant resources for modern discussions of the value of death--one which stands at the intersection of metaphysics and ethics. If death is the end of the subject, and the subject can not be benefited nor harmed after death, is it reasonable nevertheless to fear the ceasing-to-be? If the Epicureans are not right to claim that the dead can neither be benefited nor harmed, what alternative models might be offered for understanding the harm done by death and do these alternatives suffer from any further difficulties? The discussion involves consideration of both ethical and metaphysical topics since it requires analysis not only of the nature of a good life but also the nature of personal identity and time. A number of modern philosophers have offered criticisms or defences of the Epicureans' views. Warren explores and evaluates these in the light of a systematic and detailed study of the precise form and intention of the Epicureans' original arguments. Warren argues that the Epicureans also were interested in showing that mortality is not to be regretted and that premature death is not to be feared. Their arguments for these conclusions are to be found in their positive conception of the nature of a good and complete life, which divorce the completeness of a life as far as possible from considerations of its duration. Later chapters investigate the nature of a life lived without the fear of death and pose serious problems for the Epicureans being able to allow any concern for the post mortem future and being able to offer a positive reason for prolonging a life which is already complete in their terms.

This is the first volume in which an account of personal autonomy is developed that both captures the contours of this concept as it is used in social philosophy and bioethics, and is theoretically grounded in, and a part of, contemporary autonomy theory. James Stacey Taylor’s account is unique as it is explicitly a political one, recognizing that the attribution of autonomy to agents is dependent in part on their relationships with others and not merely upon their own mental (...) states. The volume is distinctive in its examples, which touch on the ethics of using inducements to encourage persons to participate in medical research, the ethical issues associated with the use of antibiotics, and the ethical basis for both patient confidentiality and informed consent.

Quentin Skinner is one of the leading thinkers in the social sciences and humanities today. Since the publication of his first important articles some two decades ago, debate has continued to develop over his distinctive contributions to contemporary political philosophy, the history of political theory, the philosophy of social science, and the discussion of interpretation and hermeneutics across the humanities and social sciences. Nevertheless, his most valuable essays and the best critical articles concerning his work have been scattered in various (...) journals and difficult to obtain. Meaning and Context includes five of the most widely discussed articles by Skinner, which present his approach to the study of political thought and the interpretation of texts. Following these are seven articles by his critics, five of these drawn from earlier publications and two, by John Keane and Charles Taylor, written especially for this volume. Finally, there appears a fifty-seven page reply by Skinner--a major new statement in which he defends and reformulates his method and lays out new lines of research. The editorial introduction provides a systematic overview of the evolution of Skinner's work and of the main reactions to it.Besides James Tully, John Keane, and Charles Taylor, the contributors include Joseph V.

A new process philosophy of signs, where process becomes primary, and fixed relation secondary'Behind Red Doors - Signs, Process and the Political' - a post by James Williams on the Edinburgh University Press blogWhat is a sign? We usually think that it is a fixed relation: a red light signifies 'Stop'. In his bold new book, James Williams now argues that signs are varying processes: seeing the red light triggers a creative response to the question, Should I stop?Williams (...) develops this new process philosophy of signs through a formal model, in contrast to earlier structuralist definitions. He draws on the philosophies of Deleuze and Whitehead, criticises earlier work on the sign in biology by Jakob von Uexküll, and connects to contemporary work on process in the philosophy of biology by John Dupré.The process model has wide applications in the arts, humanities and social sciences, and informs their critical debates with science. In defining the sign as essentially political, this radical definition of the sign opens up new possibilities for social and political critique.". (shrink)
