We have two polynomial time results for the uniform word problem for a quasivariety Q: The uniform word problem for Q can be solved in polynomial time iff one can find a certain congruence on finite partial algebras in polynomial time. Let Q* be the relational class determined by Q. If any universal Horn class between the universal closure S and the weak embedding closure S̄ of Q* is finitely axiomatizable then the uniform word problem for Q is solvable in (...) polynomial time. This covers Skolem's 1920 solution to the uniform word problem for lattices and Evans' 1953 applications of the weak embeddability property for finite partial V algebras. (shrink)

We determine precisely those locally finite varieties of unary algebras of finite type which, when augmented by a ternary discriminator, generate a variety with a decidable theory.

In an earlier paper we proved that a universal Horn class generated by finitely many finite structures has a model companion. If the language has only finitely many fundamental operations then the theory of the model companion admits a primitive recursive elimination of quantifiers and is primitive recursive. The theory of the model companion is ℵ 0 -categorical iff it is complete iff the universal Horn class has the joint embedding property iff the universal Horn class is generated by a (...) single finite structure. In the last section we look at structure theorems for the model companions of universal Horn classes generated by functionally complete algebras, in particular for the cases of rings and groups.

This paper augments Hailperin's substantial efforts to place Boole's algebra of logic on a solid footing. Namely Horn sentences are used to give a modern formulation of the principle that Boole adopted in 1854 as the foundation for his algebra of logic—we call this principle The Rule of 0 and 1.

We present two conditions which are equivalent to having an almost χ0-categorical model companion.

Through the ages, many thinkers have worried that our death fears mar our lives. Sharing this worry, the Epicureans have argued that we can live well only if we see death for what it is: a mere “nothing” that it is ill-fitting to fear. I show how this argument depends on the assumption that a mental state theory of well-being is correct. If we give up this assumption, it can be fitting to fear death. Using my philosophical discussion of when (...) and how it is fitting to fear death, I formulate three strategies for keeping our death-related fears in check. In this way, my paper follows the therapeutic tradition in philosophy, whose potential I urge effective altruists to explore. (shrink)

Jason Stanley presents a startling and provocative claim about knowledge: that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests, i.e. by how much is at stake for that person at that time. In defending this thesis, Stanley introduces readers to a number of strategies for resolving philosophical paradox, making the book essential not just for specialists in epistemology but for all philosophers interested in philosophical methodology. (...) Since a number of his strategies appeal to linguistic evidence, it will be of great interest to linguists as well. (shrink)

"This collection is obviously a labor of love. Fortunately, it is also a labor of editorial care and precision.

Decisions in security contexts, including armed conflict, law enforcement, and disaster relief, often need to be taken under circumstances of limited information, stress, and time pressure. Since AI systems are capable of providing a certain amount of relief in such contexts, such systems will become increasingly important, be it as decision-support or decision-making systems. However, given that human life may be at stake in such situations, moral responsibility for such decisions should remain with humans. Hence the idea of “meaningful human (...) control” of intelligent systems. In this opinion paper, we outline generic configurations of control of AI and we present an alternative to human control of AI, namely the inverse idea of having AI control humans, and we discuss the normative consequences of this alternative.

Based on the author's ethnographic research in India, the book explores the psychology of Hinduism, and offers an innovative synthesis of psychoanylsis with modern anthropological theories of cultural difference. Stanley N. Kurtz offers a new interpretation of the multiple "mother goddesses" of Hinduism, and explores how this multiplicity is key to understanding early childhood experience in which a child is raised by many "mothers" in the Hindu joint family. Arguing that traditional psychoanalytic approaches to Indian culture have applied Western (...) models without regard to differing cultural circumstances, Kurtz suggests that immersion in a joint family plays a central role in the development of feelings and needs which are carried over into adult life. The book concludes with a briefr comparison of mothering in India and contemporary America. _All the Mothers Are One_ makes a significant contribution to the growing debate concerning the role of psychoanalysis in the interpretation of culture and the study of cross-cultural human development.

This article focuses on Barth's explication of Anselm's Proslogion 2-4 in his book on Anselm and attempts to show how Anselm helped clarify for Barth the ontological nature of his own early theology, in particular what he meant by the “is” in his affirmation “God is God.” My contention is that Barth's continual pointing to Anselm's Fides Quaerens Intellectum as a vital key to his own theology should not be overlooked. In fact, I argue that only by returning Barth to (...) Anselm in this way is it possible to understand more thoroughly Barth's relevance to contemporary onto-theological debates. (shrink)

In Truthfulness and Tragedy Stanley Hauerwas provides an account of moral existence and ethical rationality that shows how Christian convictions operate, or should operate, to form and direct lives. In attempting to conceptualize the basis of Christian ethics in a manner that will render Christian convictions morally intelligible, the author casts fresh light on traditional theoretical issues and articulates the distinctive Christian response to contemporary concerns such as suicide, medical ethics, and child care. The first section of the book (...) deals with methodological issues: the meaning and nature of practical reason, obligation claims, natural law, and self deception, and the affinity of story and ethics. It focuses on the relation of truthfulness and tragedy and the need for a story--a set of religious convictions or "grammar of theology"--that does justice to the tragic character of human existence. The second section addresses substantive issues: suicide, euthanasia, and the value of survival; the moral limits of population growth; the definition of "person" for medical reasons; and social involvement and Christian ethics. The overall theme is the need for a community in which truthfulness is a way of life. In the final section, devoted to the problem of how to care for retarded children, the implications of the author's ethical position are given concrete expression. He discusses the assumptions underlying the willingness to have children, criteria for humanness, medical ethics, and how truthful communities deal with suffering. In Truthfulness and Tragedy Stanley Hauerwas extends and clarifies the ethical position set forth in his earlier books Character and the Christian Life and Vision and Virtue. He is associate professor of theology at the University of Notre Dame. He was a senior fellow in Christian medical ethics at the Joseph and Rose Kennedy Institute for the Study of Reproduction and Bioethics, and taught medical ethics at the University of Texas medical branch in Galveston.

This reissue of an American philosophical classic includes a new preface by Cavell, in which he discusses the work's reception and influence. The work fosters a fascinating relationship between philosophy and literature both by augmenting his philosophical discussions with examples from literature and by applying philosophical theories to literary texts. Cavell also succeeds in drawing some very important parallels between the British analytic tradition and the continental tradition, by comparing skepticism as understood in Descartes, Hume, and Kant with philosophy of (...) language as practiced by Wittgenstein and Austin.

We propose a multi-step evaluation schema designed to help procurement agencies and others to examine the ethical dimensions of autonomous systems to be applied in the security sector, including autonomous weapons systems.

_Philosophy and Animal Life_ offers a new way of thinking about animal rights, our obligation to animals, and the nature of philosophy itself. Cora Diamond begins with "The Difficulty of Reality and the Difficulty of Philosophy," in which she accuses analytical philosophy of evading, or deflecting, the responsibility of human beings toward nonhuman animals. Diamond then explores the animal question as it is bound up with the more general problem of philosophical skepticism. Focusing specifically on J. M. Coetzee's _The Lives (...) of Animals_, she considers the failure of language to capture the vulnerability of humans and animals. Stanley Cavell responds to Diamond's argument with his own close reading of Coetzee's work, connecting the human-animal relation to further themes of morality and philosophy. John McDowell follows with a critique of both Diamond and Cavell, and Ian Hacking explains why Cora Diamond's essay is so deeply perturbing and, paradoxically for a philosopher, he favors poetry over philosophy as a way of overcoming some of her difficulties. Cary Wolfe's introduction situates these arguments within the broader context of contemporary continental philosophy and theory, particularly Jacques Derrida's work on deconstruction and the question of the animal. _Philosophy and Animal Life_ is a crucial collection for those interested in animal rights, ethics, and the development of philosophical inquiry. It also offers a unique exploration of the role of ethics in Coetzee's fiction. (shrink)

In this insightful and controversial book, the eminent philosopher Stanley Rosen takes a new look at the famous 'quarrel' that the moderns have with the ancients, analyzing and comparing ancient philosophers and modern Continental and analytical thinkers from Plato, Descartes, and Kant to Fichte, Nietzsche, and Rorty. He urges that we do not dismiss the classical heritage but appropriate it, for this appropriation is an indispensable step in the process of legitimizing our historical experience.

Stanley Rosen's book is the first full-length study of the Sophist in English and one of the most complete in any language. He follows the stages of the dialogue in sequence and offers an exhaustive analysis of the philosophical questions that come to light as Theaetetus and the Eleatic Stranger pursue the sophist through philosophical debate. Rosen finds the central problem of the dialogue in the relation between original and image; he shows how this distinction underlies all subsequent technical (...) themes and analyzes in detail such problems as non-being or negation and false statement. Arguing that the dialogue must be treated as a dramatic unity, he pays careful attention throughout to the setting, the events, the language used, and the relations between the natures of the speakers and the topics under discussion. (shrink)

The first part of my hypothesis, then, is simple enough, and would be accepted in principle by most students of Plato: the dramatic structure of the dialogues is an essential part of their philosophical meaning. With respect to the poetic and mathematical aspects of philosophy, we may distinguish three general kinds of dialogue. For example, consider the Sophist and Statesman, where Socrates is virtually silent: the principal interlocutors are mathematicians and an Eleatic Stranger, a student of Parmenides, although one who (...) is not always loyal to his master's teaching of what might be called monadic homogeneity. In these dialogues, the mathematical character of philosophy is not merely emphasized but exaggerated, and any attempt to interpret them must take this fact into account. Otherwise, we shall not be able to understand why the Stranger seems to classify the general's art in the same species of the genus hunting as the louse catcher. The significance of this step, which does not stem from humanitarian considerations, but rather illustrates how the human becomes invisible from the mathematical viewpoint, contributes its share to the obscurity of these two dialogues. Second, there are dialogues like the Phaedrus and Symposium, in which the style, the interlocutors, and even the subject-matter seem to be largely poetic and rhetorical. Here, the overwhelming impression is of enthusiasm, divine madness, and intoxication in speech and deed. Finally, there are dialogues like the Philebus and Republic, in which it is not so easy to say whether poetry or mathematics predominates, if indeed either may be said to do so. (shrink)

The former Queen of Science seems to be lacking both a specific subject and a particular method. Thus the need arises for intra- and metaphilosophical orientation – especially since the way philosophy sees itself stems from various influential schools and traditions whose mutual exchange is not as lively as one might have hoped. This volume of original essays brings together some of the protagonists of different metaphilosophical debates that have so far been led fairly independently of each other. The authors (...) discuss the question of both the possibility and the scope of philosophical knowledge under a variety of aspects, particularly: (1) a priori knowledge and the role of intuitions, (2) transcendental arguments, (3) analytic philosophy and its methods as well as (4) phenomenology and analytic philosophy.

A collection of 17 important readings provide those unfamiliar with Cavell's work with an overview of its strategic purpose, its central themes, and its argumentative development. The readings are taken from every one of the major fields in which Cavell has been involved--aesthetics, philosophy of religion, philosophy of Wittgenstein, Austin, Emerson, literary criticism, film theory, and psychoanalysis. Brief editorial introductions to each piece are included. A previously unpublished essay on Wittgenstein serves as an epilogue. Annotation copyright by Book News, Inc., (...) Portland, OR. (shrink)

In these three lectures, Cavell situates Emerson at an intersection of three crossroads: a place where both philosophy and literature pass; where the two traditions of English and German philosophy shun one another; where the cultures of America and Europe unsettle one another. "Cavell’s ’readings’ of Wittgenstein and Heidegger and Emerson and other thinkers surely deepen our understanding of them, but they do much more: they offer a vision of what life can be and what culture can mean.... These profound (...) lectures are a wonderful place to make [Cavell’s] acquaintance."—Hilary Putnam. (shrink)

This handsome new edition of Stanley Cavell's landmark text, first published 20 years ago, provides a new preface that discusses the reception and influence of his work, which occupies a unique niche between philosophy and literary studies.

This book offers philosophy in the key of life.

Some fourteen years after its initial publication, this important and influential book, with a new, substantial, and candid introduction by the author, is available in a reasonably priced paperback edition. In this volume Hauerwas assesses recent interest in the "ethics of character" and suggests areas in his own work that now call for some corrective and/or further work.

Quantification is a topic which brings together linguistics, logic, and philosophy. Quantifiers are the essential tools with which, in language or logic, we refer to quantity of things or amount of stuff. In English they include such expressions as no, some, all, both, many. Peters and Westerstahl present the definitive interdisciplinary exploration of how they work - their syntax, semantics, and inferential role.

In this book, controversial and world-renowned theologian, Stanley Hauerwas, tackles the issue of theology being sidelined as a necessary discipline in the modern university. It is an attempt to reclaim the knowledge of God as just that – knowledge. Questions why theology is no longer considered a necessary subject in the modern university, and explores the role it should play in the development of our “knowledge” Considers how theology is often excluded from the knowledges of the modern university because (...) these are constituted by an understanding of time necessary to make economic and state realities seem inevitable Argues that it is precisely this difference that makes Christian theology an essential resource for the university to achieve its task - that is, to form people who are able to imagine a different world through critical and disciplined reflection Challenges the domesticated character of much recent theology by suggesting how prayer and the love of the poor are essential practices that should shape the theological task Converses with figures as diverse as Luigi Giussani, David Burrell, Stanley Fish, Wendell Berry, Jeff Stout, Rowan Williams and Sheldon Wolin Published in the new and prestigious Illuminations series.

We frequently engage in activities that impose a risk of serious harm on innocent others in order to realise trivial benefits for ourselves or third parties. Many moral theories tie the evidence-relative permissibility of engaging in such activities to the size of the risk that an individual agent imposes. I argue that we should move away from such a reliance on quantified individual risks when conceptualising morally permissible risk imposition. Under most circumstances of interest, a conscientious reasoner will identify a (...) gap between the factors they deem potentially relevant to the riskiness of an agent’s behaviour, and the factors they are reasonably able to quantify. This then leads a conscientious reasoner to conclude that they cannot, in good faith, come up with a quantitative risk estimate that is genuinely tailored to the agent’s particular situation. Based on this, I argue that principles of morally permissible risk imposition fail to provide us with practical guidance if they ask us to take into account our agent-specific risks in a quantified manner. I also argue that principles of permissible risk imposition which appeal to quantified individual risks implausibly imply that it is frequently indeterminate whether engaging in some risky activity is morally permissible. For both of these reasons, I contend that principles of morally permissible risk imposition should make no reference to quantified individual risks. They should instead acknowledge that any quantitative estimates that an agent might usefully be able to consider will likely not be tailored to the agent’s idiosyncratic situation. (shrink)

This book is a major contribution to the study of the philosophy of action, moral philosophy, and political philosophy. Its central idea is a radically unorthodox theory of rational action. Most contemporary Anglo-American philosophers believe that action is motivated by desire. Professor Benn rejects the doctrine and replaces it with a reformulation of Kant's ethical and political theory, in which rational action can be determined simply by principles, regardless of consequences. The book analyzes the way in which value conflicts can (...) be rationally resolved, the objectivity of value, the concept of moral personality, the principles of non-interference and respect of persons, the ideals of autonomy and community and various aspects of individual rights - focusing on the rights to freedom, welfare, and privacy.
