It is shown that both classical and intuitionistic propositional logics of an associative binary modality are undecidable. The proof is based on the deduction theorem for these logics.

Developing a boundary-crossing ethics by paying attention to our stories, myths, and moral intuition.

It is shown that the expressive power of second-order propositional modal logic whose modalities are S4.2 or weaker is the same as that of second-order predicate logic.

History is useful when it is used properly: to understand why we and those we must deal with think and react in certain ways. It can offer examples to inform our decisions and guesses about the consequences of our actions. But we should be wary of looking to history for dogmatic lessons.We should distrust those who abuse history when they call on it to justify unreasonable claims to land, for example, or restitution. MacMillan illustrates how dangerous history can be in (...) the hands of nationalistic or religious or ethnic leaders who use it to foster a sense of grievance and a desire for revenge. (shrink)

Humanity and the very notion of the human subject are under threat from postmodernist thinking which has declared not only the 'Death of God' but also the 'Death of Man'. This book is a revindication of the concept of humanity, rejecting contemporary social theory that seeks to diminish human properties and powers. Archer argues that being human depends on an interaction with the real world in which practice takes primacy over language in the emergence of human self-consciousness, thought, emotionality and (...) personal identity - all of which are prior to, and more basic than, our acquisition of a social identity. This original and provocative new book from leading social theorist Margaret S. Archer builds on the themes explored in her previous books Culture and Agency (CUP 1988) and Realist Social Theory (CUP 1995). It will be required reading for academics and students of social theory, cultural theory, political theory, philosophy and theology. (shrink)

How is it possible to think new thoughts? What is creativity and can science explain it? And just how did Coleridge dream up the creatures of The Ancient Mariner? When The Creative Mind: Myths and Mechanisms was first published, Margaret A. Boden's bold and provocative exploration of creativity broke new ground. Boden uses examples such as jazz improvisation, chess, story writing, physics, and the music of Mozart, together with computing models from the field of artificial intelligence to uncover the (...) nature of human creativity in the arts. The second edition of The Creative Mind has been updated to include recent developments in artificial intelligence, with a new preface, introduction and conclusion by the author. It is an essential work for anyone interested in the creativity of the human mind. (shrink)

Intention is one of the masterworks of twentieth-century philosophy in English. First published in 1957, it has acquired the status of a modern philosophical classic. The book attempts to show in detail that the natural and widely accepted picture of what we mean by an intention gives rise to insoluble problems and must be abandoned. This is a welcome reprint of a book that continues to grow in importance.

A timely and penetrating investigation, this book seeks to transform moral philosophy. In the face of continuing disagreement about which general moral principles are correct, there has been a resurgence of interest in the idea that correct moral judgements can be only about particular cases. This view--moral particularism --forecasts a revolution in ordinary moral practice that has until now consisted largely of appeals to general moral principles. Moral particularism also opposes the primary aim of most contemporary normative moral theory that (...) attempts to show that either one general principle, or a set of general principles, is superior to all its rivals.

We motivate and formalize the idea of sameness by default: two objects are considered the same if they cannot be proved to be different. This idea turns out to be useful for a number of widely different applications, including natural language processing, reasoning with incomplete information, and even philosophical paradoxes. We consider two formalizations of this notion, both of which are based on Reiter’s Default Logic. The first formalization is a new relation of indistinguishability that is introduced by default. We (...) prove that the corresponding default theory has a unique extension, in which every two objects are indistinguishable if and only if their non-equality cannot be proved from the known facts. We show that the indistinguishability relation has some desirable properties: it is reflexive, symmetric, and, while not transitive, it has a transitive “flavor.” The second formalization is an extension (modification) of the ordinary language equality by a similar default: two objects are equal if and only if their non-equality cannot be proved from the known facts. It appears to be less elegant from a formal point of view. In particular, it gives rise to multiple extensions. However, this extended equality is better suited for most of the applications discussed in this paper. (shrink)

The central problem of social theory is 'structure and agency'. How do the objective features of society influence human agents? Determinism is not the answer, nor is conditioning as currently conceptualised. It accentuates the way structure and culture shape the social context in which individuals operate, but it neglects our personal capacity to define what we care about most and to establish a modus vivendi expressive of our concerns. Through inner dialogue, 'the internal conversation', individuals reflect upon their social situation (...) in the light of current concerns and projects. On the basis of a series of unique, in-depth interviews, Archer identifies three distinctive forms of internal conversation. These govern agents' responses to social conditioning, their individual patterns of social mobility and whether or not they contribute to social stability or change. Thus the internal conversation is seen as being the missing link between society and the individual, structure and agency. (shrink)

Recognition of Hannah Arendt's contribution to the history of western philosophy is long overdue. Arendt was a 'political thinker', but this book highlights the importance of her ontological preoccupations for an understanding of her work.

Involuntary psychiatric commitment for suicide prevention and physician aid-in-dying (PAD) in terminal illness combine to create a moral dilemma. If PAD in terminal illness is permissible, it should also be permissible for some who suffer from nonterminal psychiatric illness: suffering provides much of the justification for PAD, and the suffering in mental illness can be as severe as in physical illness. But involuntary psychiatric commitment to prevent suicide suggests that the suffering of persons with mental illness does not justify ending (...) their own lives, ruling out PAD. Since both practices have compelling underlying justifications, the most reasonable accommodation might seem to be to allow PAD for persons with mental illness whose suffering is severe enough to justify self-killing, but prohibit PAD for persons whose suffering is less severe. This compromise, however, would require the articulation of standards by which persons’ mental as well as physical suffering could be evaluated. Doing so would present a serious philosophical challenge. (shrink)

Cognitive science is the project of understanding the mind by modelling its workings. Its development is one of the most remarkable and fascinating intellectual achievements of the modern era. Mind as Machine is a masterful history of cognitive science, told by one of its most eminent practitioners.

Entscheidungen verweisen in einem begrifflichen Sinne auf Gründe. Entscheidungssysteme bieten eine probabilistische Verlässlichkeit als Rechtfertigung von Empfehlungen an. Doch nicht für alle Situationen mögen Verlässlichkeitsgründe auch angemessene Gründe sein. Damit eröffnet sich die Idee, die Güte von Gründen von ihrer Angemessenheit zu unterscheiden. Der Aufsatz betrachtet an einem Beispiel, einem KI-Lügendetektor, die Frage, ob eine (zumindest aktuell nicht gegebene) hohe Verlässlichkeit den Einsatz rechtfertigen kann. Gleicht er nicht einem Richter, der anhand einer Statistik Urteile fällen würde?

This paper argues that there is a distinctive vice of hypocrisy, which is Janus-faced. The vice of hypocrisy is the self-excepting avoidance of a particular pain, namely, the pain associated with being an object of blame one believes deserved. One can self-exceptingly avoid this pain attitudinally or behaviorally. With “attitudinal” hypocrisy, a person avoids it at the level of her beliefs: she avoids forming the belief that she is blameworthy for some act, while blaming others for their comparable acts. With (...) “behavioral” hypocrisy, by contrast, a person avoids it at the level of her behavior. She shields herself from the blame she believes her acts merit (e.g. by hiding what she has done), while blaming others for their comparable acts. The paper argues that both forms of hypocrisy are objectionable and explains how they are in tension, such that a given instance of the vice will typically involve only one or the other. Though both attitudinal and behavioral hypocrisy selectively spare the hypocrite the same pain, they require incongruous moral-psychological states: the attitudinal hypocrite avoids blaming herself, while the behavioral hypocrite proceeds on the assumption she is blameworthy.

For those open to the possibility that philosophical thought can improve life, David Hume's Essays: Moral, Political, and Literary have something to say. In the first comprehensive study of the Essays, Margaret Watkins engages closely with these neglected texts and shows how they provide important insights into Hume's perspective on the breadth and depth of human life, arguing that the Essays reveal his continued commitment to philosophy as a discipline that can promote both social and individual progress. Addressing topics (...) such as politics, war, slavery, the priesthood, the development of industry, aesthetics, emotional disorders, egoism, friendship, sexuality, gender relations, and the nature of philosophy itself, the volume examines Hume's purposes and aims against the backdrop of the eighteenth century society in which he lived. It will be of interest to scholars of modern thought in philosophy, politics, history, and economics. (shrink)

Margaret Whitford's study provides the ideal introduction to Irigaray's thought, offering a sustained interpretation of her whole corpus, including previously untranslated French texts. Whitford suggests that Irigaray's work should be seen as "philosophy in the feminine," actively opposing the complicity of philosophy with other social practices which exclude or marginalize women.

Margaret Canovan argues in this book that much of the published work on Arendt has been flawed by serious misunderstandings, arising from a failure to see her work in its proper context. The author shows how such misunderstanding was possible, and offers a fundamental reinterpretation, drawing on Arendt's unpublished as well as her published work, which sheds new light on most areas of her thought.
