This much-needed book provides a thorough account of temporal logic, one of the most important areas of logic in computer science today. The book begins with a solid introduction to semantical and axiomatic approaches to temporal logic. It goes on to cover predicate temporal logic, meta-languages, general theories of axiomatization, many dimensional systems, propositional quantifiers, expressive power, Henkin dimension, temporalization of other logics, and decidability results. With its inclusion of cutting-edge results and unifying methodologies, this book is an indispensable reference (...) for both the pure logician and the theoretical computer scientist. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 38.2 (2004) 20-37 [Access article in PDF] Aesthetic Teaching Mark A. Pike I think aesthetic teaching is the highest of all teaching because it deals with life in its highest complexity. But if it ceases to be purely aesthetic — if it lapses anywhere from the picture to the diagram — it becomes the most offensive of all teaching.1George Eliot asserts that "the (...) highest of all teaching" which "deals with life in its highest complexity" is essentially aesthetic in character for it has features of the "picture" or work of art rather than the more straightforwardly instructional "diagram." Yet, George Eliot not only ascribes greatest worth to teaching that is aesthetic but considers teaching that is merely diagrammatic to be "the most offensive of all teaching." Evidently, there are similarities between pictures and diagrams but essential features present in the former are conspicuously absent from the latter. The current obsession with effectiveness in teaching and repeated attempts to reduce that which should be aesthetic and inspired to the wholly rational, diagrammatic and instrumental make George Eliot's views remarkably pertinent. Consequently, features of aesthetic teaching will be explored in this essay. In doing so it will be suggested that Martin Heidegger's ontology (theory of existence) offers a philosophical foundation for conceiving teaching in the arts as a form of engagement with students which is unreservedly aesthetic in character. As such, Heidegger provides us with a valuable position from which to counter forces that militate against the aesthetic in our schools and also provokes us to eschew all that is diagrammatic in our approach to that which is rightly aesthetic. Teaching: Drawing the Diagram or Painting the Picture? Teaching is currently being construed, in both the United Kingdom and the United States, as a technology with which to get something done or as a [End Page 20] vehicle which "delivers" a subject in an efficient or effective manner, or even as a science where the analytical approach is the method for problem solving. Even as I write, I find myself part of a proposed "delivery team" for literature education. It appears that this is the sort of language policy makers in a rational economy like to hear. Any dissenting voices, those subscribing to a view of teaching as an art itself, are considered dangerous as they jeopardize progress in our brave new world. For example, in their introduction to Effective Teaching — Evidence and Practice, Daniel Muijs and David Reynolds articulate the view that construing teaching as an art rather than a technology may be responsible for the lack of excellent teachers in our schools.2 In marked contrast to George Eliot, they suggest "the view that teaching is an 'art,' not a science" results in attention being devoted to "personal factors and qualities" which are "often idiosyncratic and difficult to influence by educational policies."3 Further, they suggest that the placing of education within the humanities tradition — is clearly wrong and probably condemns societies where it is prevalent to having only those small number of excellent teachers who inherit the "art," rather than the larger number who could acquire the applied science of a teaching methodology.4It is difficult to conceive of a position further removed from George Eliot's ideal of aesthetic teaching. There are, of course, a number of problems with reducing teaching to a technology, or an applied science, as Muijs and Reynolds prefer to call it. Such argument betrays the assumption that the world can be known in a rational, analytical and scientific way. The concomitant of this view is the misguided belief that teaching about such a world can be precisely planned, implemented and assessed. Elliot Eisner is surely more accurate when he explains that "teaching is a form of human action in which many of the ends achieved are emergent" and that these ends are often "found in the course of interaction with students rather than preconceived."5 Clearly, allowing "for the creation of ends in process" necessitates "a model of teaching akin to other arts."6 This is more...

In this paper we shall introduce a simple temporal logic suitable for reasoning about the temporal aspects of parallel universes, parallel processes, distributed systems, or multiple agents. We will use a variant of the mosaic method to prove decidability of this logic. We also show that the logic does not have the finite model property. This shows that the mosaic method is sometimes a stronger way of establishing decidability.

Modal logic is one of the most widely applied logical formalisms. Systems of modal logic are being used in many disciplines, ranging from artificial intelligence, computer science, mathematics, formal grammar and semantics to philosophy. This volume presents substantial recent advances in the relational and the algorithmic treatment of modal logics. It contains papers from the fifth conference on "Advances in Modal logic," held in Manchester (UK) in September 2004. Written by leading experts in the field, the present book is indispensable (...) for any advanced student and researcher in pure and applied modal logic. (shrink)

The Cambridge Handbook of Applied Psychological Ethics is a valuable resource for psychologists and graduate students hoping to further develop their ethical decision making beyond more introductory ethics texts. The book offers real-world ethical vignettes and considerations. Chapters cover a wide range of practice settings, populations, and topics, and are written by scholars in these settings. Chapters focus on the application of ethics to the ethical dilemmas in which mental health and other psychology professionals sometimes find themselves. Each chapter introduces (...) a setting and gives readers a brief understanding of some of the potential ethical issues at hand, before delving deeper into the multiple ethical issues that must be addressed and the ethical principles and standards involved. No other book on the market captures the breadth of ethical issues found in daily practice and focuses entirely on applied ethics in psychology. (shrink)

The design inference uncovers intelligent causes by isolating the key trademark of intelligent causes: specified events of small probability. Just about anything that happens is highly improbable, but when a highly improbable event is also specified (i.e., conforms to an independently given pattern) undirected natural causes lose their explanatory power. Design inferences can be found in a range of scientific pursuits from forensic science to research into the origins of life to the search for extraterrestrial intelligence.

We give a Hilbert style axiomatization for the set of formulas in the temporal language with Until and Since which are valid over the real number flow of time. The axiomatization, which is orthodox in the sense of only having the usual temporal rules of inference, is complete with respect to single formulas.

We present a Hilbert style axiomatisation for the set of formulas in the temporal language with F and P which are valid over non-transitive cyclical flows of time. We also give a simpler axiomatisation using the slightly controversial 'irreflexivity rule' and go on to prove the decidability of any temporal logic over cyclical time provided it uses only connectives with first-order tables.

We present an axiomatisation for the first-order temporal logic with connectives Until and Since over the class of all linear flows of time. Completeness of the axiom system is proved.We also add a few axioms to find a sound and complete axiomatisation for the first order temporal logic of Until and Since over rational numbers time.

We introduce a new way of defining metric temporal logic on a real-numbers flow of time. The idea is based on having semantics which allow us to refer to a single universal clock of arbitrary precision in order to impose metric constraints. This gives us a new metric temporal logic which is very expressive, is natural to use, can be applied in very general situations, affords a wide range of useful abbreviations and operators, has a PSPACE decision procedure, and has (...) the promise of being amenable to standard reasoning techniques. Thus it has many advantages over the existing metric temporal logics. We provide a decision procedure via conversion to a non-metric temporal logic, hence doing metric reasoning with no clocks.

Factors such as subsistence turnover, warfare, or interaction between different groups can be major sources of cultural change in human populations. Global demographic shifts such as the transition to agriculture during the Neolithic and more recently the urbanization and globalization of the twentieth century have been major catalysts for cultural change. Here, we test whether cultural traits such as patri/matrilocality and postmarital migration persist in the face of social upheaval and gene flow during the past 150 years in postcolonial South (...) Africa. The recent history of South Africa has seen major demographic shifts that resulted in the displacement and forced sedentism of indigenous Khoekhoe and San populations. During the expansion of the colonial frontier, the Khoe-San admixed with European colonists and enslaved individuals from West/Central Africa, Indonesia, and South Asia, introducing novel cultural norms. We conducted demographic interviews among Nama and Cederberg communities representing nearly 3,000 individuals across three generations. Despite the history of colonial expansion, and the subsequent incorporation of Khoe-San and Khoe-San-descendant communities into a colonial society with strong patrilocal norms, patrilocality is the least common postmarital residence pattern in our study populations today. Our results suggest that more recent forces of integration into the market economy are likely the primary drivers of change in the cultural traits examined in our study. Birthplace had a strong effect on an individual’s odds of migration, distance moved, and postmarital residence form. These effects are at least partially explained by the population size of the birthplace. Our results suggest that market factors local to birthplaces are important drivers of residence decisions, although the frequency of matrilocal residence and a geographic and temporal cline in migration and residence patterns also indicate the persistence of some historic Khoe-San cultural traits in contemporary groups.

Adequate epistemic justification is best conceived as the appearance, over time, of knowledge to the subject. ‘Appearance’ is intended literally, not as a synonym for belief. It is argued through consideration of examples that this account gets the extension of ‘adequately justified belief’ at least roughly correct. A more theoretical reason is then offered to regard justification as the appearance of knowledge: If we have a knowledge norm for assertion, we do our best to comply with this norm when we (...) express as assertions only beliefs that appear to us to be knowledge. If we are doing our best, there is little point in further sanctions. So a norm of knowledge for assertion would lead to a secondary norm of justified belief as the appearance of knowledge, marking a point at which our assertions may be corrected but should not be blamed.

This paper compares the recently proposed Robust Full Computational Tree Logic to model robustness in concurrent systems with other computational tree logic -based logics. RoCTL* extends CTL* with the addition of the operators Obligatory and Robustly, which quantify over failure-free paths and paths with one more failure respectively. This paper focuses on examining the succinctness and expressiveness of RoCTL* by presenting translations to and from RoCTL*. The core result of this paper is to show that RoCTL* is expressively equivalent to (...) CTL* but is non-elementarily more succinct. That is, RoCTL* does not add any expressive power over CTL*, but can represent some properties using vastly reduced formulae. We present a translation from RoCTL* into CTL* that preserves truth but may result in non-elementary growth in the length of the translated formula, as each nested Robustly operator may result in an extra exponential blowup. However, we show that this translation is optimal in the sense th.. (shrink)

Ludwig Wittgenstein and Martin Heidegger are arguably the two most influential philosophers of the twentieth century. Their work not only reshaped the philosophical landscape, but also left its mark on other disciplines, including political science, theology, anthropology, ecology, mathematics, cultural studies, literary theory, and architecture. Both sought to challenge the assumptions governing the traditions they inherited, to question the very terms in which philosophy’s problems had been posed, and to open up new avenues of thought for thinkers of all (...) stripes. And despite considerable differences in style and in the traditions they inherited, the similarities between Wittgenstein and Heidegger are striking. Comparative work of these thinkers has only increased in recent decades, but no collection has yet explored the various ways in which Wittgenstein and Heidegger can be drawn into dialogue. As such, these essays stage genuine dialogues, with aspects of Wittgenstein’s elucidations answering or problematizing aspects of Heidegger’s, and vice versa. The result is a broad-ranging collection of essays that provides a series of openings and provocations that will serve as a reference point for future work that draws on the writings of these two philosophers.

Mark Eli Kalderon's book boldly positions itself as a work in speculative metaphysics. Its point of departure is the familiar distinction between presentational and representational philosophies of perception. Kalderon notes that the latter has been more popular of late, as it is more amenable to "an account" explicating causal or counterfactual conditions on perception; but he wishes to rehabilitate the former, at least in part. One widely perceived disadvantage of presentationalism has been the way that understanding perception merely as (...) registering the presence of things might seem to leave us vulnerable to error about the nature of what is presented. Kalderon seeks to remedy this not by dealing at length with various disjunctivist positions concerning perception which may be friendly to his position, nor by spending much time criticising opposing views, but by explicating presentationalist perception through a series of tactile metaphors, thereby providing a radically new philosophical view. He claims that we do not just 'stand before' reality, we grasp it-the metaphor survives tellingly in ordinary language-and he thereby seeks to defend a form of realism which is robust, though he admits, "pre-modern". He draws on a remarkably rich variety of thinkers to defend this position, including pre-modern, modern, and various figures from both analytic and continental philosophy-however, although there is plenty of solid scholarship here, the book is aimed at metaphysics more than the history of ideas.

Body Integrity Identity Disorder (BIID) is a very rare condition describing those with an intense desire or need to move from a state of ability to relative impairment, typically through the amputation of one or more limbs. In this paper, I draw upon research in critical disability studies and philosophy of disability to critique arguments based upon the principle of nonmaleficence against such surgery. I demonstrate how the action-relative concept of harm in such arguments relies upon suspect notions of biological (...) and statistical normality, and I contend that each fail to provide normative guidance. I then propose a critical theory of harm, one marked by substantive engagement with both empirical and reflective inquiry across the sciences, social sciences, and humanities. I conclude by discussing the implications of this theory and how it might enrich ongoing debates in bioethics, philosophy of disability, and the health humanities. (shrink)

The Qur’an and Its Biblical Reflexes: Investigations into the Genesis of a Religion. By Mark Durie. Lanham, MD: Lexington Books, 2018. Pp. lvi + 337. $120.

The effects of the COVID-19 pandemic have rippled across the United States’ (US) agri-food system, illuminating considerable issues. US seed systems, which form the foundation of food production, were particularly marked by panic-buying and heightened safety precautions in seed fulfillment facilities which precipitated a commercial seed sector overwhelmed and unprepared to meet consumer demand for seed, especially for non-commercial growers. In response, prominent scholars have emphasized the need to support both formal (commercial) and informal (farmer- and gardener-managed) seed systems to (...) holistically aid growers across various contexts. However, limited attention to non-commercial seed systems in the US, coupled with a lack of consensus surrounding what exactly a resilient seed system looks like, first warrants an exploration into the strengths and vulnerabilities of existing seed systems. This paper seeks to examine how growers navigated challenges in seed sourcing and how this may reflect the resilience of the seed systems to which they belong. Using a mixed-methods approach which includes data from online surveys (n = 158) and semi-structured interviews (n = 31) with farmers and gardeners in Vermont, findings suggest that growers were able to adapt – albeit through different mechanisms depending on their positionality (commercial or non-commercial) within the agri-food system. However, systemic challenges emerged including a lack of access to diverse, locally adapted, and organic seeds. Insights from this study illuminate the importance of creating linkages between formal and informal seed systems in the US to help growers respond to manifold challenges, as well as promote a robust and sustainable stock of planting material.

This view of culture as a "cutting across" of boundaries, which can be found in many forms throughout his work, achieves a special significance for the study of subjectification in his discussion of "Spatial Practices" that comprises the third section of The Practice of Everyday Life. In an important essay on Certeau's theory of space, Ian Buchanan argues that "our understanding of culture must commence with an understanding of the formation of the subject," and that the latter is addressed by Certeau through his essays on space [129-30]. Following this assertion, we want to argue that Certeau's analyses of spatial practices in Heterologies, "The Gaze: Nicholas of Cusa," and The Practice of Everyday Life [particularly the chapter "Walking in the City" 91-110], outline a theory that describes subjectivity as what amounts to, as Certeau puts it in Culture in the Plural, "a composition of places and the innovation that modifies it by dint of moving and cutting across them" [146]. Furthermore, by articulating the close relationship between Certeau's spatial theory and our own work on "transversal movement," we will attempt to show that the method of analysis Certeau uses in "Walking in the City" (and describes in several other works) is itself marked by the "transversal" tactics that his theory describes. 1 By focusing in particular on Certeau's methodological critique of Foucault in both The Practice of Everyday Life and Heterologies, we will demonstrate the various ways in which he moves beyond what Bryan Reynolds and James Intriligator have labeled the "dissective-cohesive mode" of analysis, an analytical [End Page 63] [Begin Page 65] approach (characteristic of most dialectical argumentation) that breaks its subject matter into constituent parts and examines those parts with the goal of reassembling them into a unified and accountable whole (such as, say, the city or the human subject in "Walking in the City"). 2 Postmodern Space: Certeau and Jameson In his essay "Heterophenomenology, or Certeau's Theory of Space," Ian Buchanan situates Certeau's writings on the production of space within the postmodern debate over the autonomy of the subject, opposing Certeau's view to Fredric Jameson's "assumption that the subject takes his or her psychic bearings from the built environment and only has certain existence so long as he or she can cognitively 'map' this environment" [Buchanan 114]. Citing the example of the Westin Bonaventure hotel in Los Angeles, Jameson argues that "this latest mutation in space--postmodern hyperspace--has finally succeeded in transcending the capacities of the individual human body to locate itself, to organize its immediate surroundings perceptually, and cognitively to map its position in a mappable external world" [44]. The effect on cultural politics, according to Jameson, is that the subject "submerged" by this postmodern hyperspace is deprived of the "critical distance" that makes possible the "positioning of the cultural act outside of the massive Being of capital" [48]. Buchanan finds in "Walking in the City" the basis for a critique of this view though a conception of space stemming from "heterophe-nomenology," defined as "a phenomenology predicated by a heterogeneously constituted subject which does not take for granted the unity of the body" [112]. Focusing on Certeau's debt to Merleau-Ponty's theories of perception (which can best be seen in... (shrink)

In this paper I examine the role of tragedy in the ancient emergence of philosophical interiority and in the recent return of exteriority that marks the birth of theory. I argue that tragedy names a kind of epistemic threshold between systems of knowledge predicated on exteriority and interiority.

In Republic 8–9, Socrates describes four main kinds of vicious people, all of whose souls are “ruled” by an element other than reason, and in some of whom reason is said to be “enslaved.” What role does reason play in such souls? In this paper, I argue, based on Republic 8–9 and related passages, and in contrast to some common alternative views, that for Plato the “enslavement” of reason consists in this: instead of determining for itself what is good, reason (...) is forced to desire and pursue as good a goal determined by the soul’s ruler.

In De Anima II.6, Aristotle divides the objects of perception into three kinds: “special perceptibles" (idia aisthêta) such as colours, sounds and flavours, which can be perceived in their own right by only one sense; “common perceptibles" (koina aisthêta) such as shapes, sizes and movements, which can be perceived in their own right by multiple senses; and “incidental perceptibles,” such as the son of Diares, which can be perceived only “incidentally” (kata sumbebêkos). In this paper, I examine this division of (...) perceptibles and consider what it amounts to. First, I argue that Aristotle’s distinction between perceiving something in its own right (kath' hauto) and perceiving it incidentally marks a causal distinction: what is perceived in its own right causes perception as such, whereas what is perceived incidentally coincides with what is perceived in its own right. Second, I argue that for Aristotle special perceptibles, unlike common perceptibles, belong to homogeneous bodies on account of their chemical composition. Finally, I explain the primacy Aristotle assigns to special perceptibles and his claim that perception of them alone is free from error. I conclude with some brief remarks on Aristotle and the primary/secondary quality distinction. (shrink)

Aristotle is history’s most famous and influential proponent of the view that there are exactly five senses. But was he entitled to hold this view, given his other commitments? In particular, was he entitled to treat touch as a single sense, given the diversity of its correlated objects?

I also argue, contrary to what is (...) often supposed, that he was well-placed to do so, given his other commitments and views. (shrink)

Weak emergence is the view that a system’s macro properties can be explained by its micro properties but only in an especially complicated way. This paper explains a version of weak emergence based on the notion of explanatory incompressibility and “crawling the causal web.” Then it examines three reasons why weak emergence might be thought to be just in the mind. The first reason is based on contrasting mere epistemological emergence with a form of ontological emergence that involves irreducible downward (...) causation. The second reason is based on the idea that attributions of emergence are always a reflection of our ignorance of non-emergent explanations. The third reason is based on the charge that complex explanations are anthropocentric. Rather than being just in the mind, weak emergence is seen to involve a distinctive kind of complex, macro-pattern in the mind-independent objective micro-causal structure that exists in nature. The paper ends by addressing two further questions. One concerns whether weak emergence applies only or mainly to computer simulations and computational systems. The other concerns the respect in which weak emergence is dynamic rather than static. (shrink)

Weak emergence has been offered as an explication of the ubiquitous notion of emergence used in complexity science (Bedau 1997). After outlining the problem of emergence and comparing weak emergence with the two other main objectivist approaches to emergence, this paper explains a version of weak emergence and illustrates it with cellular automata. Then it explains the sort of downward causation and explanatory autonomy involved in weak emergence.

This paper describes and defends the view that minimal chemical life essentially involves the chemical integration of three chemical functionalities: containment, metabolism, and program (Rasmussen et al. in Protocells: bridging nonliving and living matter, 2009a ). This view is illustrated and explained with the help of CMP and Rasmussen diagrams (Rasmussen et al. In: Rasmussen et al. (eds.) in Protocells: bridging nonliving and living matter, 71–100, 2009b ), both of which represent the key chemical functional dependencies among containment, metabolism, and (...) program. The CMP model of minimal chemical life gains some support from the broad view of life as open-ended evolution, which I have defended elsewhere (Bedau in The philosophy of artificial life, 1996 ; Bedau in Artificial Life, 4:125–140, 1998 ). Further support comes from the natural way the CMP model resolves the puzzle about whether life is a matter of degree. (shrink)

An innocent form of emergence—what I call "weak emergence"—is now a commonplace in a thriving interdisciplinary nexus of scientific activity—sometimes called the "sciences of complexity"—that include connectionist modelling, non-linear dynamics (popularly known as "chaos" theory), and artificial life.1 After defining it, illustrating it in two contexts, and reviewing the available evidence, I conclude that the scientific and philosophical prospects for weak emergence are bright.
