We propose a domain-level ontology of plays for the facilitation of play-based collaborative autonomy among unmanned and manned-unmanned aircraft teams in the Army’s Unmanned Aircraft System (UAS) mission domain. We define a play as a type of plan that prescribes some pattern of intentional acts that are intended to reliably result in some goal in some competitive context, and which specifies one or more roles that are realized by those prescribed intentional acts. The ontology is well suited to be extended (...) to other types of military and nonmilitary unmanned vehicle operations. (shrink)
Applied ontologies have been used more and more frequently to enhance systems engineering. In this paper, we argue that adopting principles of ontological realism can increase the benefits that ontologies have already been shown to provide to the systems engineering process. Moreover, adopting Basic Formal Ontology (BFO), an ISO standard for top-level ontologies from which more domain specific ontologies are constructed, can lead to benefits in four distinct areas of systems engineering: (1) interoperability, (2) standardization, (3) testing, and (4) data (...) exploitation. Reaping these benefits in a model-based systems engineering (MBSE) context requires utilizing an ontology’s vocabulary when modeling systems and entities within those systems. If the chosen ontology abides by the principles of ontological realism, a semantic standard capable of uniting distinct domains, using BFO as a hub, can be leveraged to promote greater interoperability among systems. As interoperability and standardization increase, so does the ability to collect data during the testing and implementation of systems. These data can then be reasoned over by computational reasoners using the logical axioms within the ontology. This, in turn, generates new data that would have been impossible or too inefficient to generate without the aid of computational reasoners. (shrink)
In this reprint of Law's Empire,Ronald Dworkin reflects on the nature of the law, its given authority, its application in democracy, the prominent role of interpretation in judgement, and the relations of lawmakers and lawgivers to the community on whose behalf they pronounce. For that community, Law's Empire provides a judicious and coherent introduction to the place of law in our lives.Previously Published by Harper Collins. Reprinted by Hart Publishing.
The word "truth" retains, in common use, traces of origins that link it to trust, troth, and truce, connoting ideas of fidelity, loyalty, and authenticity. The word has become, in contemporary philosophy, encased in a web of technicalities, but we know that a true image is a faithful portrait; a true friend a loyal one. In a novel or a poem, too, we have a feel for what is emotionally true, though we are not concerned with the actuality of events (...) and characters depicted. To have emotions is to care about certain things: we can wonder whether those things are really worth caring about. We can wonder whether our passions reflect who we are, and whether they constitute fitting responses to the vicissitudes of life. So there are two aspects to emotional truth: how well an emotion reflects the threats and promises of the world, and how well it reflects our own individual nature. That is the starting point of this book, which looks first at the analogies and disanalogies between strict propositional truth and a looser, "generic" sense of truth. As applied to emotions, generic truth is closer to those original meanings: as in a portrait's fidelity or friend's loyalty. Taken in this sense, the notion of emotional truth opens up large vistas on areas of life essential to our existence as social beings, and to our concerns with beauty, morality, love, death, sex, knowledge, desire, coherence, and happiness. Each of those topics illustrates some facet of the dominant theme of the book: the crucial but often ambivalent role of our emotions in grounding and yet also sometimes undermining our values. Emotions act, in holistic perspective, as ultimate arbiters of values where different and independently justified standards of value compete. (shrink)
Professor Narveson's comments about my papers on equality are both penetrating and comprehensive. I cannot hope to discuss all the issues he raises in any detail. But there is a special problem: his main question is about what I have not said. He asks how I might defend equality of resources other than simply by describing a version of it, and of course this question will require some extended discussion. But he is right to say that this is his most (...) important question, and I should hate to lose the opportunity of encouraging discussion of it. So I shall begin with some general remarks about the defence of the idea of equality and then take up, in a very hasty and summary way, the other problems he discusses or raises. Please allow me, however, this apology and caution. I know that what I shall say about the defense of equality is at many points dogmatic and at others unmindful of very natural objections and replies. I want to answer Narveson only by showing in a rough and general way how far I think a defense of equality is possible, what kind of defense this can be, and what form it should take. (shrink)
Many people assume that the claims of scientists are objective truths. But historians, sociologists, and philosophers of science have long argued that scientific claims reflect the particular historical, cultural, and social context in which those claims were made. The nature of scientific knowledge is not absolute because it is influenced by the practice and perspective of human agents. Scientific Perspectivism argues that the acts of observing and theorizing are both perspectival, and this nature makes scientific knowledge contingent, as Thomas Kuhn (...) theorized forty years ago. Using the example of color vision in humans to illustrate how his theory of “perspectivism” works, Ronald N. Giere argues that colors do not actually exist in objects; rather, color is the result of an interaction between aspects of the world and the human visual system. Giere extends this argument into a general interpretation of human perception and, more controversially, to scientific observation, conjecturing that the output of scientific instruments is perspectival. Furthermore, complex scientific principles—such as Maxwell’s equations describing the behavior of both the electric and magnetic fields—make no claims about the world, but models based on those principles can be used to make claims about specific aspects of the world. Offering a solution to the most contentious debate in the philosophy of science over the past thirty years, Scientific Perspectivism will be of interest to anyone involved in the study of science.

Debate over the nature of science has recently moved from the halls of academia into the public sphere, where it has taken shape as the "science wars." At issue is the question of whether scientific knowledge is objective and universal or socially mediated, whether scientific truths are independent of human values and beliefs. Ronald Giere is a philosopher of science who has been at the forefront of this debate from its inception, and Science without Laws offers a much-needed mediating (...) perspective on an increasingly volatile line of inquiry. Giere does not question the major findings of modern science: for example, that the universe is expanding or that inheritance is carried by DNA molecules with a double helical structure. But like many critics of modern science, he rejects the widespread notion of science--deriving ultimately from the Enlightenment--as a uniquely rational activity leading to the discovery of universal truths underlying all natural phenomena. In these highly readable essays, Giere argues that it is better to understand scientists as merely constructing more or less abstract models of limited aspects of the world. Such an understanding makes possible a resolution of the issues at stake in the science wars. The critics of science are seen to be correct in rejecting the Enlightenment idea of science, and its defenders are seen to be correct in insisting that science does produce genuine knowledge of the natural world. Giere is utterly persuasive in arguing that to criticize the Enlightenment ideal is not to criticize science itself, and that to defend science one need not defend the Enlightenment ideal. Science without Laws thus stakes out a middle ground in these debates by showing us how science can be better conceived in other ways. (shrink)
Very often moral disagreements can be resolved by appealing to factual considerations because in these cases the parties to the dispute agree as to which factual considerations are relevant. They agree, that is, with respect to their basic moral standards. Hence, when their disagreement about the non-moral facts is resolved, so is their moral disagreement. But sometimes moral disagreement persists in spite of agreement on factual considerations. When this happens, and when neither party is guilty of illogical thinking, we have (...) a case of moral deadlock. (shrink)
Virtue ethics is now widely recognized as an alternative to Kantian and consequentialist ethical theories. However, moral philosophers have been slow to bring virtue ethics to bear on topics in applied ethics. Moreover, environmental virtue ethics is an underdeveloped area of environmental ethics. Although environmental ethicists often employ virtue-oriented evaluation and appeal to role models for guidance, environmental ethics has not been well informed by contemporary work on virtue ethics. With _Character and Environment_, Ronald Sandler remedies each of these (...) deficiencies by bringing together contemporary work on virtue ethics with contemporary work on environmental ethics. He demonstrates the many ways that any ethic of character can and should be informed by environmental considerations. He also develops a pluralistic virtue-oriented environmental ethic that accommodates the richness and complexity of our relationship with the natural environment and provides effective and nuanced guidance on environmental issues. These projects have implications not only for environmental ethics and virtue ethics but also for moral philosophy more broadly. Ethical theories must be assessed on their theoretical and practical adequacy with respect to all aspects of the human ethical situation: personal, interpersonal, and environmental. To the extent that virtue-oriented ethical theory in general, and Sandler's version of it in particular, provides a superior environmental ethic to other ethical theories, it is to be preferred not just as an environmental ethic but also as an ethical theory. _Character and Environment_ will engage any reader with an interest in environmental ethics, virtue ethics, or moral philosophy.

When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: identification of changes becomes extremely difficult, even when changes are large and made repeatedly. Identification is much faster when a verbal cue is provided, showing that poor visibility is not the cause of (...) this difficulty. Identification is also faster for objects mentioned in brief verbal descriptions of the scene. These results support the idea that observers never form a complete, detailed representation of their surroundings. In addition, results also indicate that attention is required to perceive change, and that in the absence of localized motion signals it is guided on the basis of high-level interest. (shrink)
Review text: "Ronald W. Langacker is universally acclaimed as one of the founding fathers of the cognitive linguistics movement. His pioneering efforts towards developing a meaning-oriented, usage-based theory of grammar have given cognitive linguistics many of its key concepts, and his theory of Cognitive Grammar is not only one of the cornerstones of cognitive linguistics, it is also a magnificent achievement in its own right." Dirk Geeraerts, January 2009.
This book explores a much-neglected area of moral philosophy--the typology of immorality. Ronald D. Milo questions the adequacy of Aristotle's suggestion that there are two basic types of immorality--wickedness and moral weakness--and argues that we must distinguish between at least six different types of immoral behavior. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts (...) of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Aristotle's De Anima is the first systematic philosophical account of the soul, which serves to explain the functioning of all mortal living things. In his commentary, Ronald Polansky argues that the work is far more structured and systematic than previously supposed. He contends that Aristotle seeks a comprehensive understanding of the soul and its faculties. By closely tracing the unfolding of the many-layered argumentation and the way Aristotle fits his inquiry meticulously within his scheme of the sciences, Polansky answers (...) questions relating to the general definition of soul and the treatment of each of the soul's principal capacities: nutrition, sense perception, phantasia, intellect, and locomotion. The commentary sheds light on every section of the De Anima and the work as a unit. It offers a challenge to earlier and current interpretations of the relevance and meaning of Aristotle's highly influential treatise. (shrink)

In some recent theological writing, imagination is presented as a power of the mind with crucial importance for religion, but one whose role has often suffered neglect. Its fuller acknowledgment has become a live issue today. ‘Theologians’, wrote Professor J. P. Mackey, ‘have recently taken to symbol and metaphor, poetry and story, with an enthusiasm which contrasts very strikingly with their all-but-recent avoidance of such matters’ . As well as relevant writings by Eliade and Ricoeur, there have been treatments of (...) religious imagination by Professor John Mclntyre in his Faith, Theology and Imagination and in J. P. Mackey's composite volume entitled Religious Imagination. (shrink)
I shall mean by ‘cosmic imagination’, first, the mental appropriating of objects, events, processes or patterns perceived in nature-atlarge , so as to apply them in articulating our own scheme of values , and in our quest for self-understanding. I shall apply the phrase also to the synthesising activity of the mind in our appraising of items in wider nature itself or as a whole – whether we believe nature to have no value save what we choose to confer or (...) project on it, or take it to have a value that sets limits on our appropriation, benign or exploitative.

"The Constitution is America's moral sail, and we must hold to the courage of the conviction that fills it, a conviction that we can all be equal citizens of a moral republic. That is a noble faith, and only optimism can redeem it." So writes Ronald Dworkin in the introduction to this characteristically robust and provocative new book in which Dworkin argues the fidelity to the constitution and to law demands that judges make contemporary judgements backed on political morality, (...) and why it encourages, or ought to encourage, an open display of the true grounds of judgement. The book discusses almost all of the great constitutional issues of the last two decades including abortion, affirmative action, pornography, race, homosexuality, euthanasia and free-speech and in doing so consistently offers a liberal view of the American Constitution. Dworkin's "moral reading" proposes that we all, judges, lawyers, citizens - interpret and apply the abstract language of the Constitution on the understanding that they invoke moral principles about political decency and justice. The "moral reading" therefore brings political morality into the heart of constitutional law. The various chapters of this book were first published seperately; now drawn together they bear all the hallmarks of Dworkin's legal and philosophical sophistication, his acute understanding of political process and his understanding of history. principles.

Large changes that occur in clear view of an observer can become difficult to notice if made during an eye movement, blink, or other such disturbance. This change blindness is consistent with the proposal that focused visual attention is necessary to see change, with a change becoming difficult to notice whenever conditions prevent attention from being automatically drawn to it. -/- It is shown here how the phenomenon of change blindness can provide new results on the nature of visual attention, (...) including estimates of its capacity and the extent to which it can bind visual properties into coherent descriptions. It is also shown how the resultant characterization of attention can in turn provide new insights into the role that it plays in the perception of scenes and events. (shrink)
Large changes in a scene often become difficult to notice if made during an eye movement, image flicker, movie cut, or other such disturbance. It is argued here that this _change blindness_ can serve as a useful tool to explore various aspects of vision. This argument centers around the proposal that focused attention is needed for the explicit perception of change. Given this, the study of change perception can provide a useful way to determine the nature of visual attention, and (...) to cast new light on the way that it is?and is not?involved in visual perception. To illustrate the power of this approach, this paper surveys its use in exploring three different aspects of vision. The first concerns the general nature of _seeing_. To explain why change blindness can be easily induced in experiments but apparently not in everyday life, it is proposed that perception involves a _virtual representation_, where object representations do not accumulate, but are formed as needed. An architecture containing both attentional and nonattentional streams is proposed as a way to implement this scheme. The second aspect concerns the ability of observers to detect change even when they have no visual experience of it. This _sensing_ is found to take on at least two forms: detection without visual experience (but still with conscious awareness), and detection without any awareness at all. It is proposed that these are both due to the operation of a nonattentional visual stream. The final aspect considered is the nature of visual attention itself?the mechanisms involved when _scrutinizing_ items. Experiments using controlled stimuli show the existence of various limits on visual search for change. It is shown that these limits provide a powerful means to map out the attentional mechanisms involved. (shrink)
We are causing species to go extinct at extraordinary rates, altering existing species in unprecedented ways and creating entirely new species. More than ever before, we require an ethic of species to guide our interactions with them. In this book, Ronald L. Sandler examines the value of species and the ethical significance of species boundaries and discusses what these mean for species preservation in the light of global climate change, species engineering and human enhancement. He argues that species possess (...) several varieties of value, but they are not sacred. It is sometimes permissible to alter species, let them go extinct and invent new ones. Philosophically rigorous, accessible and illustrated with examples drawn from contemporary science, this book will be of interest to students of philosophy, bioethics, environmental ethics and conservation biology.

Lev Vygotsky has acquired the status of one of the grand masters in psychology. Following the English translation and publication of his Collected Works there has been a new wave of interest in Vygotsky, accompanied by a burgeoning of secondary literature. Ronald Miller argues that Vygotsky is increasingly being 'read' and understood through secondary sources and that scholars have claimed Vygotsky as the foundational figure for their own theories, eliminating his most distinctive contributions and distorting his theories. Miller peels (...) away the accumulated layers of commentary to provide a clearer understanding of how Vygotsky built and developed his arguments. In an in-depth analysis of the last three chapters of Vygotsky's book Thinking and Speech, Miller provides a critical interpretation of the core theoretical concepts that constitute Vygotsky's cultural-historical theory, including the development of concepts, mediation, the zone of proximal development, conscious awareness, inner speech, word meaning and consciousness.

In the second of his three prefaces to On Authority and Revelation , Kierkegaard writes: ‘“My reader”, may I simply beg you to read this book, for it is important for my main effort, wherefore I am minded to recommend it’ The question I will put to myself to begin my reflections on the book is: why should Kierkegaard recommend it so strongly? What is Kierkegaard doing in this book? One notices in his recommendation that it is addressed to his (...) reader who, presumably, is not simply the reader of this book but the reader of his other books as well. The Concluding UnscientUc Postscript was being published about the same time , and so the reader may well have been familiar with most of Kierkegaard's main philosophical works. The recommendation then is set in this context. The book is, on the face of it, so unlike the other works, concerned with certain odd claims to a revelation by a Danish pastor named Adler. Much of the book discusses the details of a deposition of Adler given to the local bishop and some details of later defences which Adler gave of his revelation in several works and sermons. It appears to be a local squabble of no general interest and certainly not the sort of thing that had occupied Kierkegaard's philosophical attention to this point. The book, then, stands in need of a recommendation to Kierkegaard's reader who is not otherwise prepared for this genre. But the recommendation does not say, ‘Try this, though quite different, you may like it.’ It says rather that the reader should read it, and later he adds read it carefully, because it is ‘important for my main effort’. So the book is to be seen as of a piece with the other main works of Kierkegaard. This is what I should like to understand in the following discussion: how is this book important for Kierkegaard's main effort? (shrink)
It has long been recognized that Soren Kierkegaard's Fear and Trembling is a cryptogram. Encoded within a series of reflections and commentaries on Genesis 22 is a deeper message directed at a reader or readers presumably capable of deciphering the hidden meaning. That this is true is suggested by the book's epigraph: ‘What Tarquinius Superbus said in the garden by means of the poppies, the son understood but the messenger did not.’.
One of the more powerful impressions created by vision is that of a coherent, richly-detailed world where everything is present simultaneously. Indeed, this impression is so compelling that we tend to ascribe these properties not only to the external world, but to our internal representations as well. But results from several recent experiments argue against this latter ascription. For example, changes in images of real-world scenes often go unnoticed when made during a saccade, flicker, blink, or movie cut. This "change (...) blindness" provides strong evidence against the idea that our brains contain a picture-like representation of the scene that is everywhere detailed and coherent. (shrink)
This book develops a theory of existential security. It demonstrates that the publics of virtually all advanced industrial societies have been moving toward more secular orientations during the past half century, but also that the world as a whole now has more people with traditional religious views than ever before. This second edition expands the theory and provides new and updated evidence from a broad perspective and in a wide range of countries. This confirms that religiosity persists most strongly among (...) vulnerable populations, especially in poorer nations and in failed states. Conversely, a systematic erosion of religious practices, values and beliefs has occurred among the more prosperous strata in rich nations. (shrink)
The university has lost its way. The world needs the university more than ever but for new reasons. If we are to clarify its new role in the world, we need to find a new vocabulary and a new sense of purpose. The university is faced with supercomplexity, in which our very frames of understanding, action and self-identity are all continually challenged. In such a world, the university has explicitly to take on a dual role: firstly, of compounding supercomplexity, so (...) making the world ever more challenging; and secondly, of enabling us to live effectively in this chaotic world. Internally, too, the university has to become a new kind of organization, adept at fulfilling this dual role. The university has to live by the uncertainty principle: it has to generate uncertainty, to help us live with uncertainty, and even to revel in our uncertainty. Ronald Barnett offers nothing less than a fundamental reworking of the way in which we understand the modern university. Realizing the University is essential reading for all those concerned about the future of higher education. (shrink)
Five aspects of visual change detection are reviewed. The first concerns the concept of change itself, in particular the ways it differs from the related notions of motion and difference. The second involves the various methodological approaches that have been developed to study change detection; it is shown that under a variety of conditions observers are often unable to see large changes directly in their field of view. Next, it is argued that this “change blindness” indicates that focused attention is (...) needed to detect change, and that this can help map out the nature of visual attention. The fourth aspect concerns how these results affect our understanding of visual perception—for example, the implication that a sparse, dynamic representation underlies much of our visual experience. Finally, a brief discussion is presented concerning the limits to our current understanding of change detection. (shrink)
We show that early vision can use monocular cues to rapidly complete partially-occluded objects. Visual search for easily detected fragments becomes difficult when the completed shape is similar to others in the display; conversely, search for fragments that are difficult to detect becomes easy when the completed shape is distinctive. Results indicate that completion occurs via the occlusion-triggered removal of occlusion edges and linking of associated regions. We fail to find evidence for a visible filling-in of contours or surfaces, but (...) do find evidence for a "functional" filling-in that prevents the constituent fragments from being rapidly accessed. As such, it is only the completed structures—and not the fragments themselves—that serve as the basis for rapid recognition. (shrink)
It has often been assumed that when we use vision to become aware of an object or event in our surroundings, this must be accompanied by a corresponding visual experience (i.e., seeing). The studies reported here show that this assumption is incorrect. When observers view a sequence of displays alternating between an image of a scene and the same image changed in some way, they often feel (or sense) the change even though they have no visual experience of it. The (...) subjective difference between sensing and seeing is mirrored in several behavioral differences, suggesting that these are two distinct modes of conscious visual perception. (shrink)
