This paper provides a method for characterizing space events using the framework of conceptual spaces. We focus specifically on estimating and ranking the likelihood of collisions between space objects. The objective is to design an approach for anticipatory decision support for space operators who can take preventive actions on the basis of assessments of relative risk. To make this possible our approach draws on the fusion of both hard and soft data within a single decision support framework. Contextual data is (...) also taken into account, for example data about space weather effects, by drawing on the Space Domain Ontologies, a large system of ontologies designed to support all aspects of space situational awareness. The framework is coupled with a mathematical programming scheme that frames a mathematically optimal approach for decision support, providing a quantitative basis for ranking potential for collision across multiple satellite pairs. The goal is to provide the broadest possible information foundation for critical assessments of collision likelihood. (shrink)

This paper describes an AFOSR-supported basic research program that focuses on developing a new framework for combining hard with soft data in order to improve space situational awareness. The goal is to provide, in an automatic and near real-time fashion, a ranking of possible threats to blue assets (assets trying to be protected) from red assets (assets with hostile intentions). The approach is based on Conceptual Spaces models, which combine features from traditional associative and symbolic cognitive models. While Conceptual Spaces (...) are revolutionary, they lack an underlying mathematical framework. Several such frameworks have attempted to represent Conceptual Spaces, but by far the most robust is the model developed by Holender. His model utilizes integer linear programming in order to obtain an overall similarity value between observations and concepts that support the formation of hypotheses. This paper will describe a method for building Conceptual Spaces models for threats that utilizes ontologies as a means to provide a clear semantic foundation for this inferencing process; in particular threat ontologies and space domain ontologies are developed and employed in this approach. A space situational awareness use-case is presented involving a kinetic kill scenario and results are shown to assess the performance of this fusion-based inferencing framework. (shrink)

The overall goal of the approach developed in this paper is to estimate the likelihood of a given kinetic kill scenario between hostile spacebased adversaries using the mathematical framework of Complex Conceptual Spaces Single Observation. Conceptual spaces are a cognitive model that provide a method for systematically and automatically mimicking human decision making. For accurate decisions to be made, the fusion of both hard and soft data into a single decision framework is required. This presents several challenges to this data (...) fusion framework. The first is the challenge involved in handling multiple complex terminologies, which is addressed by drawing on a set of Space Domain Ontologies. Another challenge is the complex combinatorics involved when considering all possible feature combinations. This can be mitigated by using integer linear programming optimization that is outlined by the Complex Conceptual Spaces Single Observation mathematical model framework. A third challenge is the complicated physics that is involved in a spacecraft collision that must be addressed to obtain a better understanding of threat assessment. Overcoming these various challenges allows for a quantitative ranking for the potential of a kinetic kill collision across multiple spacecraft pairs. In addition to overcoming these challenges this paper will break down threat assessment into four domains and identify a ranking of threat both for each individual domain and for the four domains combined. Simulation results are shown to verify the developed concepts. (shrink)

Previous work has shown that the Complex Conceptual Spaces − Single Observation Mathematical framework is a useful tool for event characterization. This mathematical framework is developed on the basis of Conceptual Spaces and uses integer linear programming to find the needed similarity values. The work of this paper is focused primarily on space event characterization. In particular, the focus is on the ranking of threats for malicious space events such as a kinetic kill. To make the Conceptual Spaces framework work, (...) the similarity values between the contents of observations on the one hand and the properties of the entities observed on the other needs to be found. This paper shows how to exploit Dempster-Shafer theory to implement a statistical approach for finding these similarities values. This approach will allow a user to identify the uncertainty involved in similarity value data, which can later be propagated through the developed mathematical model in order for the user to know the overall uncertainty in the observation-to-concept mappings needed for space event characterization.

Sometimes Always True aims to resolve, through a re-understanding of the nature of sense, three connected problems central to philosophical thought: that genuine pluralism must make room for outlooks that exclude pluralism, that philosophy ultimately explores sense as a whole and so must in some way step outside of sense, and that our experience of the deep questions of life therefore similarly involves suspensions of sense itself.

The paper argues that metaphysical thought, or thought in whose context our general framework of sense is under scrutiny, involves, legitimates, and requires a variety of informal analogues of the ‘true contradictions’ supported in some paraconsistent formal logics. These are what we can call informal ‘legitimate logical inadequacies’. These paradoxical logical structures also occur in deeply pluralist contexts, where more than one, conflicting general framework for sense is relevant. The paper argues further that these legitimate logical inadequacies are real or (...) inherent in sense itself rather than conventional, shows how they can feature in argumentative practice in these metaphysical and pluralist contexts, and discusses some of their implications for metaphysical truth and for philosophical inquiry and disagreement.

This article argues that there is ultimately a very close convergence between prominent conceptions of being in mainstream Anglo‐American philosophy and mainstream postmodern Continental philosophy. One characteristic idea in Anglo‐American or analytic philosophy is that we establish what is meaningful and so what we can say about what is, by making evident the limits of sense or what simply cannot be meant. A characteristic idea in Continental philosophy of being is that being emerges through contrast and interplay with what it (...) is not, with what has no being at all and so is beyond sense. The two traditions consequently conceive being in significantly related ways. As a result, what the Continental tradition gets at with “the meaning of being as such and in general,” and how it gets at it, has much in common with what the Anglo‐American tradition gets at, and how it gets at it, by establishing “what can be meaningfully said.”.

In The Crane's Walk, Jeremy Barris seeks to show that we can conceive and live with a pluralism of standpoints with conflicting standards for truth--with the truth of each being entirely unaffected by the truth of the others. He argues that Plato's work expresses this kind of pluralism, and that this pluralism is important in its own right, whether or not we agree about what Plato's standpoint is.The longest tradition of Plato scholarship identifies crucial faults in Plato's theory (...) of Ideas. Barris argues that Plato deliberately displayed those faults, because he wanted to demonstrate that basic kinds of error or illogic have dimensions that are crucial to the establishing of truth. These dimensions legitimate a paradoxical coordination of logically incompatible conceptions of truth. Connecting this idea with emerging currents of Plato scholarship, he emphasizes, in addition to the dialogues' arguments, the importance of their nonargumentative features, including drama, myths, fictions, anecdotes, and humor. These unanalyzed nonargumentative features function rigorously, as a lever with which to examine the enterprise of rational argument itself, without presupposing its standards or illegitimately assimilating any position to the standards of another.Today, communities are torn apart by conflicts within and between a host of different pluralist and absolutist commitments. The possibility developed in this book-a coordination of absolute and relative truth that allows an understanding of some relativist and some absolutist positions as being fully legitimate and as capable of existing in a relation to their opposites-may contribute to perspectives for resolving these conflicts.

Fogelin’s Wittgensteinian view of deep disagreement as allowing no rational resolution has been criticized from both argumentation theoretic and epistemological perspectives. These criticisms typically do not recognize how his point applies to the very argumentative resources on which they rely. Additionally, more extremely than Fogelin himself argues, the conditions of deep disagreement make each position literally unintelligible to the other, again disallowing rational resolution. In turn, however, this failure of sense is so extreme that it partly cancels its own meaning (...) as a failure of sense. Consequently, it paradoxically opens new possibilities for sense and therefore rationally unexpected resolutions. (shrink)

Paradox and the Possibility of Knowledge argues that psychoanalytic theory has certain mostly unnoticed features that bring out, with unusual clarity, a logic that is true of conceptual thought generally. This logic is paradoxical in that it is deliberately and productively self-canceling. The general relevance of this logic to conceptual thought and to theory offers a solution to some fundamental epistemological problems. First, it allows a solution to the problem of the ultimate circularity or infinite regress of knowledge, by showing (...) how the circle or regress eliminates itself in a variety of successful knowledge-grounding ways. Second, it offers some resulting insights into issues involving politically troublesome dimensions of knowledge, specifically into the procedure of ethical political dialogue. The book is written in the contexts of both Anglo-American philosophy and Continental or European philosophy. The argument is largely Wittgensteinian, and at the same time proceeds through detailed reference to Freud's and Lacan's work. On the way it addresses theory construction in general, including the claims of phenomenology and deconstruction. (shrink)

The paper proposes with Davidson that the talk of metaontology is literally meaningless, but with Wittgenstein that it is so in a way that grants a unique type of insight. More specifically, it argues both that Davidson’s arguments have a cogency that is hard to dismiss, and also that, since his own arguments are metaontological, they are self-referential, and consequently in turn undermine their own meaning as well. The paper argues further that metaontological statements cannot be avoided. Consequently, this kind (...) of statement constitutes an unavoidable self-referential paradox that means what it also excludes as capable of meaning. The result is a reinstatement of the meaning of ontological insight and in fact, the paper argues, a deep enrichment and also a particularly cogent justification of it. In addition, the logical peculiarity of the paradox involved has further useful consequences for the outcome of this justification, including a mutually illuminating commonality with some versions of metaethics.

What distinguishes philosophy is its attention to reality and sense as such, or what is traditionally called being and essence. As a result, philosophy as a way of life is, most fundamentally, not directly a matter of doing one kind of thing rather than another outside the classroom but instead of how we live with respect to our being. Enacting our being in one way rather than another inflects whatever it is we do. Consequently, even if we only study philosophy (...) in the conventional, apparently unlived way in the classroom, we are in active relation to our being and therefore fully living philosophy as a way of life.

The paper argues that dreams consist partly in an awareness or experience of the conceptual fabric of our existence. Since what we mean by reality is intimately tied to the concepts given in our experience, dreams are therefore also partly an awareness of the fabric of what we mean by being itself and in general, that is, by objective as well as subjective reality. Further, the paper argues that this characteristic of dreams accounts for several other, more specific aspects of (...) dreams and their possible interpretation, and that it allows us to see how these aspects are related to each other. These more specific aspects are the peculiar types of conceptual or logical relations and transitions that occur within dreams, dreams’ distinctive feeling texture, and some dimensions of the grounds and nature of suitable methods of interpreting dreams.

The paper tries to show that when the deepest or foundational aspects of truth are at issue, both consequentially logical argument and rhetoric that aims to establish truth or justified conviction must engage with the being, or the irreplaceable particularity, of its audience’s members and also that of the arguer, what we refer to in ordinary language as who the person is. Beyond the existing discussion of existential rhetoric, the paper argues that this engagement with being is necessary to establish (...) not only truth that directly concerns or turns on the arguer’s and audience’s being, but also truth or justification about fundamental aspects of things and issues in general. Further, the address of being requires us to suspend both our own and our addressees’ familiar conceptual frameworks in order to allow being to emerge in its own terms. As a result, in contrast with our usual understanding of argumentation, the rhetorician’s initial aim and procedure will be to achieve a genuine suspension of conviction and even of the appropriate concepts under which to proceed, and so to produce a fundamental confusion. The paper then outlines some consequences for rhetoric and reasoning and also the structure of the process of working with this fundamental confusion. (shrink)

We want to propose a conception of wisdom with a view to exploring what insights it can give us into some basic dimensions of teaching in contemporary higher education. We hope to show that this conception allows us, on the one hand, to see some crucial inadequacies of existing approaches to critical thinking, multiculturalism, and global awareness or internationalism. On the other hand, we believe that it also gives us some insight into the existentially or spiritually meaningful dimensions of learning. (...) In this way, it bridges the most contemporary and practical foci of teaching and its most fundamental and timeless concerns. In the later part of the paper, we shall explore some of the characteristics of this conception further through the teachings of some of the longstanding wisdom traditions, including what they say about teaching itself.

If we accept that at least some kinds of nonhuman animals are persons, a variety of paradoxes emerge in our ethical relations with them, involving apparently unavoidable disrespect of their personhood. We aim to show that these paradoxes are legitimate but can be illuminatingly resolved in the light of an adequate understanding of the nature of persons. Drawing on recent Western, Daoist, and Zen Buddhist thought, we argue that personhood is already paradoxical in the same way as these aspects of (...) our ethical relations with nonhuman animals, and in fact is the source of their paradoxical character. In both contexts, depth and shallowness turn out to be internal to or crucial parts of each other, with logically anomalous consequences. We try to show that the character of this paradoxical relation between depth and shallowness in the nature of personhood involves a crucial inflection in the case of nonhuman animal persons that allows us to make sense of and resolve these ethical paradoxes.

Philosophy often at least implicitly includes and depends on a logical structure which is also that of jokes. This is the case when philosophy involves questioning or establishing concepts in their own right, and when it involves the kinds of metaphysics which ask about reality and the world as a whole or as such. Taking this humour-like structure into account in presenting philosophy helps, among other things, to lay open part of the character of philosophy itself, to underscore the radical (...) self-perspective that is constitutive of philosophy, and to contextualise the often confusing experience of coming to grips with an unfamiliar philosophical framework.

It is a challenge in teaching early modern philosophy to balance historical faithfulness to the arguments and concerns of early modern philosophers and interpreting them as relevant to the kinds of thinking that contemporary undergraduate students find plausible. Early modern philosophy is unique, however, in applying modern scientific method directly to problems concerning nonphysical aspects of reality that our contemporary scientific thought, and with it mainstream contemporary culture, no longer find amenable in their own, independent right to reliable reasoned approaches. (...) At the same time, early modern philosophy often also takes seriously purely conceptual or logically consequential thought in the investigation of these topics, as our mainstream contemporary culture does not. This kind of thought, we argue, is distinctive of philosophy in general and appropriate to nonphysical aspects of reality. Early modern philosophy, then, offers a bridge between the kind of reasoned, objective thought our mainstream culture finds plausible and thought about nonphysical reality or, in general, the thought that characterizes philosophy.

Abstract: This article considers how the formal structure of metaphysical thought is displayed in Oscar Wilde's Importance of Being Earnest . One frequent aim of metaphysics is to understand the world as a whole. We cannot gain such a global vantage point without separating ourselves from all the particular meanings things have for us within the world. But we start within the world, and so can only proceed on the basis of those particular meanings. Consequently we can only separate ourselves (...) from them if they work to cancel themselves in favor of the global understanding. When the separate range of meanings is established, however, it and the world it aims to understand no longer have any meaning for each other. Metaphysics therefore succeeds by establishing and canceling its relevant meaning, all at once. This self-canceling moment or process of thought constitutes a grasp of the world as a whole. It also allows different understandings of reality as a whole to recognize and so enter into dialogue with each other. The climactic moments of The Importance of Being Earnest are structured as a map of this insight-granting process of the self-cancellation of a global range of meanings. That is, they express the formal structure of metaphysical thought. (shrink)

The article proposes an analogue of conceptual change in the context of comprehensive or deep emotional change and growth, and explores some aspects of its logic in that context. This is not to reduce emotions to concepts, but to say that concepts express the sense that is already inherent in experience and reality. When emotional states change so thoroughly that their applicable concepts become completely different, they shift from one logical structure to another. At the moment or phase when one (...) conceptual structure transforms into another, two logically incompatible descriptions both apply to the same state at the same time. As a result, the correct description of this moment and its development involves conceptual confusion, non sequitur, and logical contradiction. In these contexts, the sense itself of the emotional experience and process is partly characterized by what are otherwise violations of sense. Failure of sense is part of how these experiences make sense. The article explores some of the consequences of this paradox of sense for the nature and experience of deep emotional change and for the meaning of change itself in this context. (shrink)

The article argues that there is a central problem with the concept of public philosophy, in that philosophy is partly defined by questioning reflection on its own sense, while public or popular culture characteristically relies unreflectively on its ultimate givens, and these are mutually exclusive modes of thought. The article proposes, however, that because of philosophy’s reflection on and potential questioning of its own sense it has a paradoxical structure of foundational and comprehensive conflict with itself and its own procedure, (...) and that this self-divergence allows a genuinely philosophical role for public philosophy. In the public context, acknowledged failure to understand beyond a certain point makes room for a limitation of sense that incompletely but effectively substitutes for the properly philosophical explicit and questioning reflection on the nature of sense as such and on the possibility that even what we do understand about the relevant issues fails to have sense.

The parceling of land into real estate is more than a simple geometrical affair. Real estate is a historical product of interaction between human beings, political, legal and economic institutions, and the physical environment. And while many authors, from Jeremy Bentham to Hernando de Soto, have drawn attention to the ontological (metaphysical) aspect of property in general, no comprehensive analysis of landed property has been attempted. The paper presents such an analysis and shows how landed property differs from other (...) types of property in a way which implies a special role for political and economic philosophy of property rights in land. This is the Chinese translation of "The Metaphysics of Real Estate", Topoi, 20: 2 (September 2001), 161–172. (shrink)

Author Jeremy Waldron has thoroughly revised thirteen of his most recent essays in order to offer a comprehensive critique of the idea of the judicial review of legislation. He argues that a belief in rights is not the same as a commitment to a Bill of Rights. This book presents legislation by a representative assembly as a form of law making which is especially apt for a society whose members disagree with one another about fundamental issues of principle.

Proponents of the rule of law argue about whether that ideal should be conceived formalistically or in terms of substantive values. Formalistically, the rule of law is associated with principles like generality, clarity, prospectivity, consistency, etc. Substantively, it is associated with market values, with constitutional rights, and with freedom and human dignity. In this paper, I argue for a third layer of complexity: the procedural aspect of the rule of law; the aspects of rule-of-law requirements that have to do with (...) "natural Justice" or "procedural due process." These I believe have been neglected in the jurisprudential literature devoted specifically to the idea of the rule of law and they deserve much greater emphasis. Moreover procedural values go beyond elementary principles like the guarantee of an unbiased tribunal or the opportunity to present and confront evidence. They include the right to argue in a court about what the law is and what its bearing should be on one's situation. The provision that law makes for argument is necessarily unsettling, and so this emphasis on the procedural aspect highlights the point predictability should not be regarded as the be-all and end-all of the rule of law. (shrink)

Political theorist Jeremy Waldron makes a bracing case against identifying rule of law with predictability. Seeing the rule of law as just one value to which democracies aspire, he embraces thoughtfulness rather than rote rule-following, flexibility even at the cost of vagueness, and emphasizing procedure and argument over predictable outcomes.

This volume collects two lectures by Jeremy Waldron that were originally given as Berkeley Tanner Lectures along with responses to the lectures from Wai Chee Dimock, Don Herzog, and Michael Rosen; a reply to the responses by Waldron; and an introduction by Meir Dan-Cohen.

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)

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.

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.

How is what we believe related to how we act? That depends on what we mean by ‘believe’. On the one hand, there is what we're sure of: what our names are, where we were born, whether we are sitting in front of a screen. Surety, in this sense, is not uncommon — it does not imply Cartesian absolute certainty, from which no possible course of experience could dislodge us. But there are many things that we think that we are (...) not sure of. For example, you might think that it will rain sometime this month, but not be sure that it will. Both what we're sure of and what we think have important normative connections to action. But the connections are quite different. This paper explores these issues with respect to assertion, inquiry, and decision making. We conclude by arguing that there is no theoretically significant notion of ‘full belief’ intermediate in strength between thinking and being sure. (shrink)

Consider the sentence “Lois knows that Superman flies, but she doesn’t know that Clark flies”. In this paper we defend a Millian contextualist semantics for propositional attitude ascriptions, according to which ordinary uses of this sentence are true but involve a mid-sentence shift in context. Absent any constraints on the relevant parameters of context sensitivity, such a semantics would be untenable: it would undermine the good standing of systematic theorizing about the propositional attitudes, trivializing many of the central questions of (...) epistemology, the philosophy of mind, and the philosophy of action. In response to this problem, we prove a series of tenability results. We show that, given certain constraints on the parameters of context sensitivity, there is a broad class of principles of propositional attitude psychology whose good standing follows from corresponding claims about people’s mental representations. But these constraints also have some surprising consequences: they are jointly incompatible with coarse-grained theories of propositions, and they are in tension with a natural picture of how speakers and hearers coordinate on the interpretation of attitude ascriptions. In light of these consequences we explore different ways in which the contextualist picture might be developed, and argue that our preferred way compares favorably with Fregeanism and neo-Russellianism.
